1、这个方法是实现锁屏状态下唤醒手机,亮屏并解锁屏幕:
public static void wakeUpAndUnlock(Context context){
//屏锁管理器
KeyguardManager km= (KeyguardManager) context.getSystemService(Context.KEYGUARD_SERVICE);
KeyguardManager.KeyguardLock kl = km.newKeyguardLock("unLock");
//解锁
kl.disableKeyguard();
//获取电源管理器对象
PowerManager pm=(PowerManager) context.getSystemService(Context.POWER_SERVICE);
//获取PowerManager.WakeLock对象,后面的参数|表示同时传入两个值,最后的是LogCat里用的Tag
PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.ACQUIRE_CAUSES_WAKEUP | PowerManager.SCREEN_DIM_WAKE_LOCK,"bright");
//点亮屏幕
wl.acquire();
//释放
wl.release();
}
加入权限:
<uses-permission android:name="android.permission.WAKE_LOCK"/>
<uses-permission android:name="android.permission.DISABLE_KEYGUARD"/>
2、这个收集的:
//锁屏、唤醒相关
private KeyguardManager km;
private KeyguardLock kl;
private PowerManager pm;
private PowerManager.WakeLock wl;
private void wakeAndUnlock(boolean b)
{
if(b)
{
//获取电源管理器对象
pm=(PowerManager) getSystemService(Context.POWER_SERVICE);
//获取PowerManager.WakeLock对象,后面的参数|表示同时传入两个值,最后的是调试用的Tag
wl = pm.newWakeLock(PowerManager.ACQUIRE_CAUSES_WAKEUP | PowerManager.SCREEN_BRIGHT_WAKE_LOCK, "bright");
//点亮屏幕
wl.acquire();
//得到键盘锁管理器对象
km= (KeyguardManager)getSystemService(Context.KEYGUARD_SERVICE);
kl = km.newKeyguardLock("unLock");
//解锁
kl.disableKeyguard();
}
else
{
//锁屏
kl.reenableKeyguard();
//释放wakeLock,关灯
wl.release();
}
}
说明:
getSystemService取不到就获取上下文对象getActivity().getSystemService()。
