Android(安卓)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">
