Question

yesterday I noticed the possibility to integrate Fragments in older API Levels through the Compatibility package, but thats not really essential for the question. 🙂

I have a Button with an OnClickListener

Button button = (Button) findViewById(R.id.button);
button.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
        doSomething();
        button.setPressed(true);
    }
});

Because of the actual clicking, it is shown as pressed and after releasing the click, the button state is not pressed and stays that way.

Is there a simple way that keeps the button state pressed after releasing?
First thing I can think of would be some sort of timer, but that seems unreasonable.

You can keep the button states in xml file under drawable folder, then used as background for button.
For example:

 android:background="@drawable/buttonstate"

buttonstate.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true" android:drawable="@drawable/back_focused" />
    <item android:drawable="@drawable/back" /> <!-- default -->
</selector>
