Android全屏设置及取消全屏设置

1、//在onCreat方法中setContentView（）之前插入

requestWindowFeature(Window.FEATURE_NO_TITLE);//取消标题栏

getWindow().setFlags(WindowManager.LayoutParams. FLAG_FULLSCREEN ,

              WindowManager.LayoutParams. FLAG_FULLSCREEN);//全屏

注：这种方法在启动activity时会闪现状态栏之后再全屏

2、在manifest里面配置：<activity android:theme="@android:style/Theme.NoTitleBar.Fullscreen" />只在当前Activity内显示全屏

<application  android:theme="@android:style/Theme.NoTitleBar.Fullscreen"  />为整个应用配置全屏显示

3、/**

 * 全屏切换

 */

public void fullScreenChange() {

SharedPreferences mPreferences = PreferenceManager.getDefaultSharedPreferences(this);

boolean fullScreen = mPreferences.getBoolean("fullScreen", false);

WindowManager.LayoutParams attrs = getWindow().getAttributes(); 

System.out.println("fullScreen的值:" + fullScreen);

if (fullScreen) {

attrs.flags &= (~WindowManager.LayoutParams.FLAG_FULLSCREEN); 

getWindow().setAttributes(attrs); 

//取消全屏设置

getWindow().clearFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);

mPreferences.edit().putBoolean("fullScreen", false).commit() ;

} else {

attrs.flags |= WindowManager.LayoutParams.FLAG_FULLSCREEN; 

getWindow().setAttributes(attrs); 

getWindow().addFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS); 

mPreferences.edit().putBoolean("fullScreen", true).commit();

}

}
