Colorizing the Title Bar

It’s very interesting if we can do some customizing over title bar on screen, like this:

Colorizing Title Bar

Here the tricks:

package pete.android.study;

import android.app.Activity;
import android.graphics.Color;
import android.os.Bundle;
import android.view.View;
import android.view.ViewParent;
import android.widget.TextView;

public class MainActivity extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        // load title bar from Android layout
        TextView titleBar = (TextView)getWindow().findViewById(android.R.id.title);
        if (titleBar != null) {
            // set text color, YELLOW as sample
            titleBar.setTextColor(Color.YELLOW);
            // find parent view
            ViewParent parent = titleBar.getParent();
            if (parent != null && (parent instanceof View)) {
                // set background on parent, BRICK as sample
                View parentView = (View)parent;
                parentView.setBackgroundColor(Color.rgb(0x88, 0x33, 0x33));
            }
        }
    }
}

If you want to do some customization on default Android screen layout by re-construct the framework, then refer to this file: platforms/android-2.3.3/data/res/layout/screen.xml, whereas replace 2.3.3 by your version.

Have fun
