Answer 1

自定义窗口标题.xml

public class CustomWindowTitle extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);

        setContentView(R.layout.main);

        getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.window_title);
    }
}

window_title.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal"
    android:layout_width="fill_parent"
    android:layout_height="35dip"
    android:gravity="center_vertical"
    android:paddingLeft="5dip"
    android:background="#323331">

    <ImageView
        android:id="@+id/header"
        android:src="@drawable/header"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"/>

</LinearLayout>
