方法1：AndroidManifest.xml
裡，Activity的 android:theme 指定為" @android:style/Theme.NoTitleBar.Fullscreen"
示例:
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme=" @android :style/Theme.NoTitleBar.Fullscreen">
<activity
android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
方法2： 在onCreate()裡指定No title
要加入：
/*set it to be no title*/
requestWindowFeature(Window.FEATURE_NO_TITLE);
/*set it to be full screen*/
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
示例：
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
/*set it to be no title*/
requestWindowFeature(Window.FEATURE_NO_TITLE);
/*set it to be full screen*/
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_main);

<application
