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>

ORYou can use Color instead of Background.hope it helps.

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.

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.
