将操作栏更改为透明颜色，以在Android 2和Android 3上均可使用

Question

I get this nice piece of code from http://developer.android.com/resources/samples/ActionBarCompat/index.html , which able to make ActionBar GUI on both Android 2 and Android 3 platform.

However, I was wondering, had anyone tried to change the color of ActionBar . Note that, the following code will make crash at Android 2, as in Android 2, it doesn't have ActionBar .

public void onCreate(Bundle savedInstanceState) {           
    ...
    getActionBar().setBackgroundDrawable(getResources().getDrawable(R.drawable.ad_action_bar_gradient_bak));        
}

Answer 1

使用ActionBarSherlock就像魅力一样:)
