方法一：使用系统服务
PowerManager pm= (PowerManager) mContext.getSystemService(Context.POWER_SERVICE);
if(!pm.isScreenOn())
{
//熄屏状态
}
方法二：使用广播
public class ScreenReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(Intent.ACTION_SCREEN_OFF)) {
//收到亮屏广播
} else if (intent.getAction().equals(Intent.ACTION_SCREEN_ON)) {
//收到熄屏广播
}
}
}
//注册广播
ScreenReceiver sOnBroadcastReciver=new ScreenReceiver();
IntentFilter recevierFilter=new IntentFilter();
recevierFilter.addAction(Intent.ACTION_SCREEN_ON);
recevierFilter.addAction(Intent.ACTION_SCREEN_OFF);
registerReceiver(sOnBroadcastReciver, recevierFilter); //取消注册
if(sOnBroadcastReciver!=null)
{
unregisterReceiver(sOnBroadcastReciver);
}
注意：亮屏和熄屏广播只能通过动态注册才能收到。
