调用BroadcastReceiver时如何解锁屏幕？

<receiver android:name=".MyBroadcastReceiver">
    <intent-filter>
        <action android:name="android.intent.action.USER_PRESENT" />
    </intent-filter>
</receiver>

public class MyBroadcastReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();
        if (action.equals(Intent.ACTION_USER_PRESENT)) {
            // 在这里处理解锁屏幕事件
            // 可以执行一些操作，如启动一个Activity、发送通知等
        }
    }
}

Intent unlockIntent = new Intent(Intent.ACTION_USER_PRESENT);
context.sendBroadcast(unlockIntent);
