1. 方法1：AndroidManifest.xml 里，Activity的 android:theme指定为" @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>

2. 方法2： 在onCreate()里指定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);
