Android实现隐藏状态栏和标题栏

隐藏标题栏需要使用预定义样式：android:theme=”@android:style/Theme.NoTitleBar”.
隐藏状态栏：android:theme=”@android:style/Theme.NoTitleBar.Fullscreen”.

         <action android:name="android.intent.action.MAIN" />
         <category android:name="android.intent.category.LAUNCHER" />
       </intent-filter>
     </activity>

</manifest> 

 

 

@Override
public void onCreate(Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);
   // hide titlebar of application
   // must be before setting the layout
   requestWindowFeature(Window.FEATURE_NO_TITLE);
   // hide statusbar of Android
   // could also be done later
   getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
       WindowManager.LayoutParams.FLAG_FULLSCREEN);
   setContentView(R.layout.main);
   text = (EditText) findViewById(R.id.EditText01);
    }
