The two textviews are both wrap_content. and they will show dynamic characters. how can I put the picture between them. and make the edge of picture have the same distance to both of them. I am a new of English and android developer. has anyone can understand me and do me a favor? thanks a lot.
To make the edge of picture have the same distance to two textviews, You can use the LinearLayout with layout_weight. Here is developer link for LinearLayout
Try below code:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#android:color/white"
tools:context=".MainActivity"
android:orientation="vertical"
android:padding="10dp"
android:gravity="center">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:gravity="center">
<LinearLayout
android:layout_weight=".35"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:gravity="end|right|center_vertical">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Text One"/>
</LinearLayout>
<LinearLayout
android:layout_weight=".3"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:gravity="center">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#mipmap/ic_launcher"/>
</LinearLayout>
<LinearLayout
android:layout_weight=".35"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:gravity="center_vertical">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Text Two"
android:gravity="center_vertical"/>
</LinearLayout>
</LinearLayout>
</LinearLayout>
Output for above code like below:
I hope this helps you

How do I make my items visible when running the application?
In your simple layout code, there are many problems. For example:
1.
android:layout_width="409dp"
android:layout_height="729dp"
such android screen size is hard to get. And in Android layout principal, you'd better use relative layout rather than such hard code size. Here you can replace it with match_parent or wrap_content.
In the same way.
android:layout_height="638dp"
totally over screen height ,make no space for hllsend to show.
I suggest you learn some android layout principal before write android app.
It's not a good practice to add LinearLayout in ConstraintLayout and I think it's the issue with your code you just need to make you LinearLayout as a parent and remove your ConstraintLayout.
NOTE: please do necessary adjustment.
Please check quick example for your code I didn't run this.

put all your xml codes in LinearLayout and remove ConstraintLayout . thats may helps.
I have implemented a persistent bottom sheet in my layout - one that cannot be completely hidden but always peeks from the bottom.
But it covers the last RecyclerView item.
How can I set the layout in such a way the peek doesn't hide the last item?

Just needed to add android:paddingBottom attribute to the RecyclerView.

I am very new to android designing and have some basic problems setting up a
simple layout:
Here are my goals:
I would like to have two buttons at the end of the Screen, each having the same size, filling the width of the screen.
A second LinearLayout should fill the rest of the screen, but all its content should be vertically centred.
I tried my best, but sometimes my bottom LinearLayout completely disappears, sometimes the bottom one looks fine, but the other layouts content isn't centred. I just don't know what to try out anymore. Here is what I got so far:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center">
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:id="#+id/editTableName"
android:hint="#string/TableNameHint" />
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:id="#+id/editTableDescripion"
android:hint="#string/TableDescriptionHint" />
<EditText
android:inputType="textPassword"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:hint="#string/TablePasswordHint"
android:id="#+id/TablePassword"
android:fontFamily="sans-serif" />
</LinearLayout>
<LinearLayout
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom">
<Button
android:id="#+id/BtnAddTable"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="#string/BtnAddTable" />
<Button
android:id="#+id/BtnCancelAddTable"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="#string/BtnCancelAddTable"
/>
</LinearLayout>
</LinearLayout>
I tried my best, but sometimes my bottom LinearLayout completely disappears, sometimes the bottom one looks fine, but the other layouts content isn't centred.
Your button is sometimes disappearing because your top sub Linearlayout's height is match_parent, which makes it fill the parent's height and cover the below views.
What you need is a layout structure like below:
Description:
So like the description in the picture, you can set weightsum to your parent layout and set the weight percentage to your sub layout. And wrap your button's Linearlayout using Relativelayout, so that you can get the buttons centered.
Codes:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:weightSum="4">
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:layout_gravity="center">
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:id="#+id/editTableName"
android:hint="#string/TableNameHint" />
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:id="#+id/editTableDescripion"
android:hint="#string/TableDescriptionHint" />
<EditText
android:inputType="textPassword"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:hint="#string/TablePasswordHint"
android:id="#+id/TablePassword"
android:fontFamily="sans-serif" />
</LinearLayout>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="3">
<LinearLayout
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:layout_gravity="bottom">
<Button
android:id="#+id/BtnAddTable"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="#string/BtnAddTable" />
<Button
android:id="#+id/BtnCancelAddTable"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="#string/BtnCancelAddTable" />
</LinearLayout>
</RelativeLayout>
</LinearLayout>
Update:
RelativeLayout has restrictions, it can only contain one child. So if you want to add more widgets in the bottom region then the best option for you is to use ConstraintLayout.
For Xamarin, you can follow the below steps:
Open Android SDK Manager in your VS:
Tools->Other->Check below versions of Constraintlayout and solver for Android like below and apply changes:
Install Xamrin.Android.Support.Constraint.Layout to your project through nuget package:
Then use the following xml codes:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">
<EditText
android:id="#+id/editText"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Name" />
<EditText
android:id="#+id/editText2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Name"
app:layout_constraintTop_toBottomOf="#+id/editText" />
<EditText
android:id="#+id/editText3"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_constraintTop_toBottomOf="#+id/editText2" />
<android.support.constraint.Guideline
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/guideline"
app:layout_constraintGuide_percent="0.6"
android:orientation="horizontal"/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_constraintBottom_toBottomOf="#id/guideline"
android:orientation="horizontal">
<Button
android:id="#+id/button"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="Button"/>
<Button
android:id="#+id/button2"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="Button"/>
</LinearLayout>
</android.support.constraint.ConstraintLayout>
Short Explaination:
use android.support.constraint.Guideline with app:layout_constraintGuide_percent="0.6" to draw an invisible line to help position the buttons.(guideline will be 60% from the top screen). Then let buttons' stacklayout to be bottom of the guideline.
For detail usage of ConstraintLayout, please refer to Build responsive UI with ConstraintLayout.
Well, what you are trying to do is more achievable by just adding a Relative layout to the mix:
What you have to do is this:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="6"
android:layout_gravity="center">
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:id="#+id/editTableName"
android:hint="#string/TableNameHint" />
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:id="#+id/editTableDescripion"
android:hint="#string/TableDescriptionHint" />
<EditText
android:inputType="textPassword"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:hint="#string/TablePasswordHint"
android:id="#+id/TablePassword"
android:fontFamily="sans-serif" />
</LinearLayout>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true">
<LinearLayout
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
>
<Button
android:id="#+id/BtnAddTable"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="#string/BtnAddTable" />
<Button
android:id="#+id/BtnCancelAddTable"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="#string/BtnCancelAddTable"
/>
</LinearLayout>
</RelativeLayout>
</LinearLayout>
RelativeLayout:
The Official Android developer website says :
RelativeLayout is a view group that displays child views in relative positions. The position of each view can be specified as relative to sibling elements (such as to the left of or below another view) or in positions relative to the parent RelativeLayout area (such as aligned to the bottom, left or centre).
I wish to make 2 by 2 image using LinearLayout with you equal weight. Can someone please assist me thanks. Your help will be appreciated thanks
I am trying to get my xml for my Android app working but I have some problems. I am trying to display to equal sized 2 images side by side in a linear layout. There has to be a margin between them, on both sides right and left, and on top.
MY code can only give me 3 images but I need 4 images.
I'd appreciate any help solving this problem
This is my code:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horiztontal"
android:weightSum="2">
<ImageView
android:id="#+id/imageView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
/>
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1"
android:weightSum="2">
<ImageView
android:id="#+id/imageView2"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1" />
<LinearLayout

<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/imageView3"
android:layout_weight="1" />
</LinearLayout>
</LinearLayout>
use following layout
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent"

android:weightSum="2">
<ImageView
android:layout_margin="10dp"
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="match_parent" />
<ImageView
android:layout_margin="10dp"
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="match_parent" />
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:orientation="horizontal"
android:weightSum="2">
<ImageView

<ImageView
android:layout_margin="10dp"
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="match_parent" />
</LinearLayout>
</LinearLayout>
Note:further you can optimize this layout using Relative or ConstrainLayout.
Use the Code split 4 images equally
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_weight="1">
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:layout_margin="5dp"
android:id="#+id/imageview"/>
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:layout_margin="5dp"
android:id="#+id/imageview1"/>
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/linear2"
android:orientation="horizontal"
android:layout_weight="1">
<ImageView

<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:layout_margin="5dp"
android:id="#+id/imageview14"/>
</LinearLayout>
Each Image View Set the Scaletype property to set as FitXY
I've been making my way through thenewboston's android tutorials and I'm stuck on number 35. There is supposed to be a scroll bar that takes up a weight of 30 at the top of the app. There are 6 textview/edittext field groups in the code, but I deleted 5 for simplicity. My problem is that all of the text and text boxes appear on the page and are not confined to the given weight (they all just show up on the page). Has anyone else had this problem or know how to fix it?
Please, I'm new to stackoverflow. If you think this is a stupid question, please explain to me why and how I can ask it better.

Welcome to StackOverflow!
Couple of things,
TheNewBoston made a mistake. Whenever you use weights you need
to set the height (or width) of that element to 0dp. I've changed
that in your code.
You shouldn't rely on the xml tool that eclipse has, you should always try to launch your app to some type of a device (emulator or preferably hardware)
I think by ScrollBar, you mean ScrollView? Because you're not doing anything to control the appearance of the scroll bar right now.
The parent of your layout (in this case) should match_parent, not wrap. (this is your main issue)
Also, you don't really need weightSum, android will just sum all the weights anyway.
<ScrollView
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="30" >

You need to set the height of the views to 0dp if you are using weight. match_parent is causing problems. Also set the height of root view to match_parent. Try this, if I add many EditText's to the LinearLayout in the ScrollView it seems to give the effect you are after:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:weightSum="100">
<ScrollView
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="40">

android:text="TextView"/>
<EditText
android:id="#+id/editText1"

android:layout_height="wrap_content"
