Android 自定义窗口标题

1>提供自定义标题界面，如： R.layout.title
2>在Activity的onCreate()方法中添加如下代码：

public class MainActivity 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.title);
    }
    
    public void add(View v){
    	Toast.makeText(this, "按钮被点击", 1).show();
    }
}

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal"
	>

    <TextView 
        android:layout_width="wrap_content"
    	android:layout_height="match_parent"
    	android:textColor="#FF0000"
        android:text="自定义标题"
        />
    
    <Button
        android:layout_width="wrap_content"
    	android:layout_height="wrap_content"
    	android:text="添加"
    	android:onClick="add"
        />
</LinearLayout>

3>为Activity设置主题，修改系统默认标题样式：

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="testTheme" parent="android:Theme">
         <item name="android:windowContentOverlay">@drawable/nonecolor</item>
		 <item name="android:windowTitleSize">44dp</item>
		 <item name="android:windowTitleBackgroundStyle">@style/testbg</item>
    </style>
    
    <style name="testbg">
        <item name="android:background">@drawable/rectangle</item>
    </style>
</resources>

AndroidManifest.xml

<activity android:name=".MainActivity" android:theme="@style/testTheme">
