Android 設置Activity 全屏的方法

1、代碼實現

public void onCreate(Bundle savedInstanceState)
	{
		super.onCreate(savedInstanceState);
		//==============注意要在加載setContentView(R.layout.main)之前設置，不然程序崩潰===============
		 //無title     
          requestWindowFeature(Window.FEATURE_NO_TITLE);   
		//全屏
		getWindow().setFlags(WindowManager.LayoutParams. FLAG_FULLSCREEN ,                
          WindowManager.LayoutParams. FLAG_FULLSCREEN);  
		//==============注意要在加載setContentView(R.layout.main)之前設置，不然程序崩潰===============
		setContentView(R.layout.main);
	}

2、在AndroidManifest.xml的Activity 屬性中設置

android:theme="@android:style/Theme.NoTitleBar.Fullscreen"

<activity android:name="com.dapai178.chesshall.ExpandableListViewTest"
            	  android:theme="@android:style/Theme.NoTitleBar.Fullscreen" >
        </activity>
