Changing Background Color of the Layout on a Button Click in Android

Change layout background color on button click

Shared preferences could be your solution. Oncreate of every activity check for the variable and set the color.

public void onClick(View v){
        switch (v.getId()){
        case R.id.blue:
            backgroundColor("blue");
            break;
 }
}


private void backgroundColor(String color) {
        // TODO Auto-generated method stub
        SharedPreferences prefs = getSharedPreferences("BackgroundColor", MODE_PRIVATE);
          SharedPreferences.Editor editor = prefs.edit();
          editor.clear();
          editor.putString("Color", color);
          editor.commit();
    }

In other Activities

SharedPreferences prefs = getSharedPreferences("BackgroundColor",
                  MODE_PRIVATE); 
String bgcolor = prefs.getString("Color","Anydefaultcolor");

now you can set your layout to bgcolor

Android Change background color when clicked

This is because by default when the button is touched it will take click instead of focus.If you want button to be focused and change its color when pressed add this to your button in xml.

android:focusableInTouchMode="true"

Button - Change background color on click

Create a shape named button_pressed.xml

<shape xmlns:android="http://schemas.android.com/apk/res/android">

    <solid android:color="@color/blue" />

    <stroke
        android:width="4dp"
        android:color="@color/blue" />

    <padding
        android:bottom="1dp"
        android:left="1dp"
        android:right="1dp"
        android:top="1dp" />

</shape>

Suppose, you have two buttons whose IDs are R.id.btn and R.id.btn1

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <Button
        android:id="@+id/btn"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_margin="12dp"
        android:background="@drawable/button_pressed"
        android:onClick="onClick"
        android:text="Press Me 1" />

    <Button
        android:id="@+id/btn2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_margin="12dp"
        android:background="@drawable/button_pressed"
        android:onClick="onClick"
        android:text="Press Me 2" />

</LinearLayout>

Write the onClick() method which will allow you to retain the changed color until another button is pressed.

Button button;

public void onClick(View v) {

    Drawable dr = getResources().getDrawable(R.drawable.button_pressed);
    dr.setColorFilter(Color.parseColor("#FF0000"), PorterDuff.Mode.SRC_ATOP);

    switch (v.getId()) {
    case R.id.btn:

        if (button == null) {
            button = (Button) findViewById(v.getId());
        } else {
            button.setBackgroundResource(R.drawable.button_pressed);
            button = (Button) findViewById(v.getId());
        }
        button.setBackgroundDrawable(dr);

        break;

    case R.id.btn2:
        if (button == null) {
            button = (Button) findViewById(v.getId());
        } else {
            button.setBackgroundResource(R.drawable.button_pressed);
            button = (Button) findViewById(v.getId());
        }
        button.setBackgroundDrawable(dr);

        break;

    default:
        break;
    }
}

I think, now you will get What you wanted to do.

Unable to change button background color on click

When I click the button the color changes and disappears I want it to stay until user press any other button

You have no code to do that. A Button does not have a durable state that changes when the use clicks on it. You will have to do something yourself, in Java/Kotlin code, to do that.

For example, you could toggle the activated state via setActivated() on the Button. Then, in your btn_selector resource, you could have different drawables for android:state_activated="true" than for android:state_activated="false".

Android button background color

If you want to keep the general styling (rounded corners etc.) and just change the background color then I use the backgroundTint property

android:backgroundTint="@android:color/holo_green_light"

How to change background of a button in android and retain it after few seconds

This works fine with me you need to make view final so you can access it inside handler body

buyNow.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(final View view) {
            view.setBackgroundColor(Color.RED); //set the color to red
            // Delay of 2 seconds (200 ms) before changing back the color to black
            final Handler handler = new Handler();
            handler.postDelayed(new Runnable() {
                @Override
                public void run() {
                    view.setBackgroundColor(Color.BLACK); //set the color to black
                }
            }, 200);
        }
    });
