2. Make button for different states Normal, focused and pressed state. You can also choose a different button for just any one of the states. Here i have created just two buttons. For focused state it will be the same as Normal state.
Focused – Displays when button is focused using keypad or otherwise.
Normal – Displays normally
Pressed – Displays when button is pressed
3. This is the important part, here we will be making XML file (custom_button.xml) in res/drawable folder.
You can make different files and keep according to the device resolution in drawable-hdpi, drawable-mdpi, drawable-ldpi.
The custom_button.xml file-
<?xml version=”1.0″ encoding=”utf-8″?>
<selector xmlns:android=”http://schemas.android.com/apk/res/android”>
<item android:drawable=”@drawable/pressed”
android:state_pressed=”true” />
<item android:drawable=”@drawable/focused”
android:state_focused=”true” />
<item android:drawable=”@drawable/normal” />
</selector>
Remember that this must be the order of the different states of buttons, otherwise it will not work. This custom_button.xml file must be set as background to android:button, we’ve already done it in the main layout.
android:background=”@drawable/selector_button” />
4. Now in the MainActivity.java just add the button and the layout and you are done.
I have not used a focusable mode, but if you want a different respone for focusable then you will need to set if focusable like this imageButton1.setFocusableInTouchMode(true);
public class MainActivity extends Activity {
Button imageButton;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
imageButton = (Button) findViewById(R.id.imageButtonSelector);
}
}
