Android全屏設置及取消全屏設置

• 1、//在onCreat方法中setContentView（）之前插入
• requestWindowFeature(Window.FEATURE_NO_TITLE);//取消標題欄
• getWindow().setFlags(WindowManager.LayoutParams. FLAG_FULLSCREEN ,
•               WindowManager.LayoutParams. FLAG_FULLSCREEN);//全屏
• 注：這種方法在啟動activity時會閃現狀態欄之后再全屏
• 2、在manifest里面配置：<activity android:theme="@android:style/Theme.NoTitleBar.Fullscreen" />只在當前Activity內顯示全屏
• <application  android:theme="@android:style/Theme.NoTitleBar.Fullscreen"  />為整個應用配置全屏顯示
• 3、/**
•  * 全屏切換
•  */
• 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); 
• //取消全屏設置
• 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();
• }
• }
