Android app开发：息屏状态下唤醒屏幕

方式1：申请wake_lock唤醒屏幕

//权限：
<uses-permission android:name="android.permission.WAKE_LOCK" />


@SuppressLint("InvalidWakeLockTag")
private void wakeUp() {
    PowerManager powerManager = (PowerManager) getSystemService(POWER_SERVICE);
    Log.d(TAG, "wjz debug wakeUp: screen is on ? == " + powerManager.isInteractive());
    if (!powerManager.isInteractive()) {
        //屏锁管理器
//            KeyguardManager km = (KeyguardManager) getSystemService(Context.KEYGUARD_SERVICE);
//            KeyguardManager.KeyguardLock kl = km.newKeyguardLock("unLock");
//            //解锁
//            kl.disableKeyguard();

        PowerManager.WakeLock wakeLock = powerManager.newWakeLock(PowerManager.ACQUIRE_CAUSES_WAKEUP | PowerManager.SCREEN_DIM_WAKE_LOCK, "cyg_wake");

        //点亮屏幕
        wakeLock.acquire(1000L);
        //释放
        wakeLock.release();
    }
}

方式2：代码模拟按下power键唤醒屏幕

PowerManager powerManager = (PowerManager) getSystemService(POWER_SERVICE);
Log.d(TAG, "wjz debug openCamera: screen is on ? == " + powerManager.isInteractive());
if (!powerManager.isInteractive()) {
    mThreadPool.execute(new Runnable() {
        @Override
        public void run() {
            try {
                Instrumentation inst = new Instrumentation();
                inst.sendKeyDownUpSync(KEYCODE_POWER);
                Log.d(TAG, "wjz debug openCamera: 唤醒屏幕!!!!!!!!!!!!!!!!!!!!!!!!");
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    });
}
