Android全屏显示

全屏显示
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();
}
