Android如何使Activity全屏

1. public class FullScreen extends Activity {  
2.     @Override  
3.     public void onCreate(Bundle savedInstanceState) {  
4.         super.onCreate(savedInstanceState);  
5.   
6.         requestWindowFeature(Window.FEATURE_NO_TITLE);  
7.         getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,   
8.                                 WindowManager.LayoutParams.FLAG_FULLSCREEN);  
9.   
10.         setContentView(R.layout.main);  
11.     }  
12. }  

Alternatively you can add

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

to AndroidManifest.xml under <activity>

 

但是经过尝试，发现还需要在AndroidMainfest里设置：

 <uses-sdk android:minSdkVersion="?"

，否则无法正确全屏，原因不清楚。折腾了好久。
