My Flutter app uses Google Pay as a payment method. Following these guidelines, they provide XML buttons (which I have never dealt with).
How can I add one of these button to a flutter widget using dart?
There are different implementations for laying out content for Android versus Flutter.
The layout/googlepay_button.xml layout effectively describes the way the button appears, and drawable/googlepay_button_content.xml contains VectorDrawable file for the Google Pay button. flutter_svg should help you render the contents of the image.
To get this to work with Flutter, you would need to reproduce the xml layout as a Flutter widget tree.
Sample layout black/res/layout/googlepay_button.xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:clickable="true"
android:focusable="true"
android:layout_width="match_parent"
android:layout_height="48sp"
android:background="#drawable/googlepay_button_no_shadow_background"
android:paddingTop="2sp"
android:contentDescription="#string/googlepay_button_content_description">
<LinearLayout
android:duplicateParentState="true"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:weightSum="2"
android:gravity="center_vertical"
android:orientation="vertical">
<ImageView
android:layout_weight="1"
android:layout_width="match_parent"
android:layout_height="0dp"
android:scaleType="fitCenter"
android:duplicateParentState="true"
android:src="#drawable/googlepay_button_content"/>
</LinearLayout>
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="fitXY"
android:duplicateParentState="true"
android:src="#drawable/googlepay_button_overlay"/>
</RelativeLayout>
It looks like SVG. Try to open all these XML files like SVG, and add it to assets folder in your project.

I'm new in android. I want to show activity by moving up and down. (We can see it in many music players). But I don't know how to do it. Please give me some solutions, examples or suggestions.
Как дела?
Suggestion: You may find all crazy animation, including 2D and 3D animation in the following link. I did not have enough time find the exact one but I am sure they exist in this following collection.

Advice: You can easily achieve it with Animation APIs in Android SDK. Or you may find some relevant answers here
Make activity animate from top to bottom
Good luck.
Finally, I decided to use Android Bottom Sheet. Here is code example:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/bottom_sheet"
android:layout_width="match_parent"
android:layout_height="340dp"
android:background="#android:color/darker_gray"
android:orientation="vertical"
app:behavior_hideable="true"
app:behavior_peekHeight="80dp"
app:layout_behavior="android.support.design.widget.BottomSheetBehavior">
<TextView
android:layout_width="match_parent"
android:layout_height="80dp"
android:background="#color/colorAccent"
android:gravity="center"
android:text="#string/bottom_sheet_peek"
android:textColor="#android:color/white" />
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:text="#string/bottom_sheet_content"
android:textColor="#android:color/white" />
</LinearLayout>
I want to drag and drop elements into the Design View but I just can't. I can't even see the attributes aside when click into the screen or the default TextView that says 'Hello World!'. I tried restarting Android Studio, rebuild the project, and I still have the problem.
The code below is from my file 'activity_main.xml'.
How did happened?
I just tried to add a 'GridLayout' into the screen design, but to use it I had to install a library to use that grid layout and since I did that, I can't use the design view anymore.
Even I get an 'IDE Fatal Error' (screenshot below).

<?xml version="1.0" encoding="utf-8"?>

Remove
implementation 'com.android.support.constraint:constraint-layout:+'
from your build.gradle (app)

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.
I am new to both Stack Overflow and Android Studio and learning to code now.
I did a basic user and password layout in Android Studio like this:
When I ran this on emulator, it displays the widgets like this:
I tried to change the width of the EditText fields, buttons, but nothing I have tried seems to be working.
How do I solve this?
What am I missing or am I doing something wrong ?

Your layout's parent is a ConstraintLayout, but it's lacking every constraint. ConstraintLayout is characterised by the ability to set constraints to every view, forcing its behaviour across screens of different sizes and orientations.
If you really want to use a ConstraintLayout I suggest taking a look at the ConstraintLayout Documentation. Once you've properly set the constraints, you should have an xml like this (note the constraint* attributes in my Views.
So, your layout has no constraints, it's likely it will end at "random" positions. Moreover, you've set the views coordinates with tools, which is valid only for the layout preview, not for runtime. And moreover, the use of absolute coordinates is very not recommended, since it can cause problems across different screen sizes.
If ConstraintLayout is an optional choice for you, you can change the layout parent to a LinearLayout with vertical orientation, I think it's more suitable for the layout you're building (I'm assuming this by your screenshots).Hope I helped, let me know. Good luck and happy coding!
Please see below:
I tried using Absolute layout, but that's deprecated. I appreciate your help, thanks.
RelativeLayout is a great option.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<ImageView
android:id="#+id/icon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="5dp"
android:scaleType="centerCrop"
android:src="#drawable/iconImage" />
<ImageView
android:id="#+id/badge"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignRight="#+id/icon"
android:layout_alignTop="#+id/icon"
android:src="#drawable/badge" />
If you actually want a badge with a dynamic number/text, then you can make the second ImageView a TextView (or a ViewGroup such as LinearLayout or RelativeLayout) and give it a background drawable and set the text to what you want.
Have a look at the ViewBadger project on github(but keep in mind that you shouldn't try to copy other platforms UI elements in android apps).
