How Can I Reduced The Padding of My Toolbar - android-studio

Good day, can you help me with this one?
I add icons on my toolbar, the problem is, it took too much space.
How can I reduced them? To look Like this one below
minTarget is - 15 to 23 present.
Here's my code:
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:elevation="4dp"
android:layout_margin="0dp"
android:padding="0dp"
android:minHeight="?android:attr/actionBarSize"
android:background="#color/colorPrimary"
app:layout_scrollFlags="scroll|enterAlways"
app:contentInsetLeft="0dp"
app:contentInsetStart="0dp" />

GridLayout with variable row height in Xamarin

I have a fairly simple Xamarin app with a primary interface that consists of two ImageViews, one overlayed on the other. The images are the same size, and I want them to expand to fill the screen. Except that I want the bottom 100 pixels (about) reserved for a banner ad.
Without the ad, I found this simple. I used a RelativeLayout, set the layout_height and layout_width to match_parent, put both images in it, and set layout_CenterInParent to true for both of them. It works great.
And then I went to put the banner in. I tried using a GridLayout with one column and two rows, putting the prior RelativeLayout inside the top cell and the banner inside the bottom cell. But unless I restrict the height of the RelativeLayout to a fixed height, it expands until the banner is invisible. And I don't want to restrict it to a fixed height, because I want to expand it to the full height minus the banner height.
I realize that there's a basic contradiction between filling a space and restricting the height, but I'm hoping that there's some solution for this.
In css, I can use heights like wh-100 to be the full window height minus 100 pixels. Is there anything similar in Xamarin? Failing that, is there any trick I can use to achieve what I'm trying to do?

Thanks for any help.
At first, if you use the GridLayout , you can set the control's height as the parent's - 100 in the xml. But you can use the row height to set the control's height such as:
<GridLayout
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:minWidth="25px"
android:minHeight="25px"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:rowCount="2"
android:columnCount="1"
android:id="#+id/gridLayout1">
<RelativeLayout
android:minWidth="25px"
android:minHeight="25px"
android:id="#+id/relativeLayout1"
android:layout_width="wrap_content"
android:layout_height="400px"
android:layout_row="0"
android:layout_rowWeight="3"
android:background="#ffff44">
<ImageView
android:id="#+id/img1"
android:src="#drawable/img1"
android:layout_centerInParent="true"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
<ImageView
android:id="#+id/img2"
android:src="#drawable/img2"
android:layout_centerInParent="true"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
</RelativeLayout>
<RelativeLayout
android:minWidth="100px"
android:minHeight="100px"
android:layout_height="100px"
android:layout_row = "1"
android:layout_rowWeight="3"
android:id="#+id/relativeLayout2"
android:layout_width="wrap_content"
android:background="#ccff44">
<ImageView
android:id="#+id/banner_placeholder"
android:src="#drawable/banner_placeholder"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
</RelativeLayout>
This will set the first RelativeLayout's height as 3/4 of the parent and the second as the 1/4.
If you still want to set the first RelativeLayout's height as parent's - 100, you can use the ConstraintLayout instead of the GridLayout. And you need to install the package named Xamarin.AndroidX.ConstraintLayout at first.
And then:
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto">
<RelativeLayout
android:id="#+id/layout1"
app:layout_constraintBottom_toBottomOf="parent"
android:layout_width="match_parent"
android:layout_height="100dp"/>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="0dp" // in the ConstraintLayout the odp means use the rest area in the parent
app:layout_constraintBottom_toTopOf="#+id/layout1"
app:layout_constraintTop_toTopOf="parent"/>
</androidx.constraintlayout.widget.ConstraintLayout>
In addition, the ConstraintLayout is the most using layout in the native android, it can design many effects which is hard for the other layouts to implement.

I have a layout that contains relative layout with two vertical linear layouts that displays on a zebra MC67

But the same activity blows up loading on a zebra m6000. Let me state that I am a novice using Android Studio and Java. I have been a VB programmer for many years.
The XML has 2 includes. One foe each vertical linear layout. I can add the XML's for them if needed.
What could cause the rendering to work on one android device (which is running an earlier version of OS ) but fail on newer device.
Here is XML
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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="#color/colorBackgroundGray"
tools:context="com.procatdt.stockright.activities.PutAwayAreaActivity">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
>
<include
android:id="#+id/include2"
layout="#layout/frm1"
android:layout_width="wrap_content"
android:layout_height="0dp"
android:layout_weight="1"
android:layout_gravity="left" />
</LinearLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:paddingLeft="5dp"
android:orientation="vertical">
<include
android:id="#+id/include"
layout="#layout/layout_numpad5"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_marginStart="220dp"
android:layout_weight="1"
android:layout_gravity="right"
/>
</LinearLayout>
</RelativeLayout>
Here is how it is rendering on MC67
Found Issue. One of the Buttons in my include was the culprit. KitKat didn't care but lollipop didn't like the backgroundtint value.
Looking through logcat I saw culprit was a button and from there it was process of elimination.

Android Keyboard, custom popuplayout in Nougat

i developed a keyboard that works without issue on MM and lower. By the way on Nougat i have a layout issue, check this images to understand better: http://imgur.com/a/IHfeZ.
The 1st image is on Nougat ( the popup isn't showed completely) the 2nd is like appeared on MM ( all the lines are showed correctly ).
I used this xml to customize the popup:
<?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="wrap_content"
android:orientation="horizontal"
android:background="#color/aosp_pressed">
<android.inputmethodservice.KeyboardView
android:layout_gravity="bottom"
android:id="#android:id/keyboardView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:keyPreviewLayout="#layout/preview"
android:keyBackground="#drawable/key_background"
android:keyTextColor="#fff"
android:background="#color/aosp_background"
android:keyTextSize="25sp"/>
<ImageButton android:id="#android:id/closeButton"
android:background="#color/aosp_pressed"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_marginStart="8dp"
android:layout_marginEnd="8dp"
android:clickable="true"
android:src="#drawable/ic_close_black" />
</LinearLayout>
As you can see the issue is caused by the position of the popup that isn't showed outside the keyboard. How can i solve this issue?
Thanks in advance to everyone.
What is your #layout/preview like?
My theory is that in between Android 6 and 7, the time when wrap_content chooses it's size changed.
Before when using
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal">
<TextView
android:id="#+id/xxxxx"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1">
</LinearLayout> //PARTIAL CODE!
there were no problems in 6.0. The text view would expand to fit the text and then be centered.
However, in 7, the text gets displayed completely vertically suggesting that the initial LinearLayout was getting set to a width of 0 and not adjusting.
Try playing with the height in your #layout/preview, or in your closeButton. Set them to manual heights and see if things change accordingly!

android layout: constant size of bottom view

I just started learning Android and got a problem implementing a special layout. I read a lot about layouts and tried everything that crossed my mind, but i couldnt solve it. Probably its very easy and I would be very grateful for your help!
I need a simple layout, having a bigger view at the top and a smaller one at the bottom. The lower view should have a constant size of 150dp, the upper view should be variable in height and fill the rest . It is no problem giving the upper one a constant size and the lower one the rest - but thats not the way i need it...
Thats a simplified screenshot how it should look like:
Screenshot
Thanks a lot!
Here you go:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<RelativeLayout
android:id="#+id/rl_layout_one"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#android:color/holo_blue_light"
android:layout_above="#+id/rl_layout_two">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ic_launcher"
android:layout_centerInParent="true"/>
</RelativeLayout>
<RelativeLayout
android:id="#+id/rl_layout_two"
android:layout_width="match_parent"
android:layout_height="150dp"
android:background="#android:color/darker_gray"
android:padding="15dp"
android:layout_alignParentBottom="true">
</RelativeLayout>
</RelativeLayout>
This matches your expectation. Howerev, i would like to point out that generally, layout height or width are not specified.It is bad practice. I would suggest another option, using LinearLayouts with weights, find the code below.
<?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="1">
<RelativeLayout
android:id="#+id/rl_layout_one"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#android:color/holo_blue_light"
android:layout_weight="0.4">
</RelativeLayout>
<RelativeLayout
android:id="#+id/rl_layout_two"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#android:color/darker_gray"
android:padding="15dp"
android:layout_weight="0.6">
</RelativeLayout>
</LinearLayout>
Hope these help.
EDIT 1:
Check the 1st solution, it was missing the layout_above attribute, that is why it took the whole screen space and centered the image according to the whole screen space. Now, it will not, since layout one is above layout two, it will center your image according to layout one.

Change position of Fragment in DrawerLayout dynamically when openDrawer and closeDrawer

I used a lot of time to solve my problem, but I can't find a way to do it.
My problem is something like the picture in link: http://goo.gl/dffOhJ
(Sorry, I do not have reputation enough to post image)
My main_layout.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="end"
android:background="#F78B1E"
android:minHeight="?attr/actionBarSize" />
<android.support.v4.widget.DrawerLayout
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center_vertical">
<!-- The main content view -->
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<!-- The navigation drawer -->
<ListView
android:id="#+id/left_drawer"
android:layout_width="210dp"
android:layout_marginLeft="5dp"
android:layout_marginTop="5dp"
android:layout_height="wrap_content"/>
</android.support.v4.widget.DrawerLayout>
My question is how can I dynamically change position of Fragment when Drawer open or close?
Can anyone help me.
Thank in advance :)
Implement DrawerListener and in its callback: onDrawerSlide(View drawerView, float slideOffset) change position of content_frame (translate horizontally).
