Button - Change background color on click

use this selector & put it in drawable folder & set button background to this selector.

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

<item android:drawable="@color/blue" android:state_pressed="true"/>
<item android:drawable="@color/AliceBlue" android:state_focused="true"/>  
<item android:drawable="@color/Azure"/>

 </selector>

OR You can use Color instead of Background. hope it helps.

I suggest you this selector.

Just create a simple selector.xml file in drawable folder and then add the selector to your button as android:background="@drawable/selector" or by code like this: yourButton.setBackground(getResources().getDrawable(R.drawable.selector));

selector.xml:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_enabled="true"
        android:state_pressed="true" android:drawable="@android:color/holo_blue_light" />
    <item android:state_enabled="true"
        android:state_focused="true" android:drawable="@android:color/holo_green_dark" />
    <item android:state_enabled="true"
        android:state_selected="true" android:drawable="@android:color/holo_purple" />
    <item
        android:drawable="@drawable/yourdrawable" />
</selector>

The first item is for pressed, the second for focused and the last is for selected state.

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.
