Android Studio用代码唤醒手机屏幕并解锁

试过几个方案，只有这个好用。

public static Context context;
    /**
     * 唤醒手机屏幕并解锁
     */
    public static void wakeUpAndUnlock() {
        // 获取电源管理器对象
        PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
        boolean screenOn = pm.isInteractive();
        if (!screenOn) {
            // ScreenOn是LogCat里用的Tag
            PowerManager.WakeLock wl = pm.newWakeLock(
                    PowerManager.ACQUIRE_CAUSES_WAKEUP |
                            PowerManager.SCREEN_BRIGHT_WAKE_LOCK, "ScreenOn");
            wl.acquire(1000); // 点亮屏幕
            wl.release(); // 释放
        }
        // 屏幕解锁
        KeyguardManager keyguardManager = (KeyguardManager) context.getSystemService(KEYGUARD_SERVICE);
        KeyguardManager.KeyguardLock keyguardLock = keyguardManager.newKeyguardLock("unLock");
        // 屏幕锁定
        keyguardLock.reenableKeyguard();
        keyguardLock.disableKeyguard(); // 解锁
    }

在onCreate()中加入：

context = this;
