锁屏以及解锁监听

锁屏以及解锁监听

屏幕锁屏以及解锁时会分别发送SCREEN_ON和SCREEN_OFF广播，但是这两个广播只能通过代码的形式注册才能被监听到，在AndroidManifest.xml中注册根本监听不到。

public class ScreenActionReceiver extends BroadcastReceiver {
    private boolean isRegisterReceiver = false;

    @Override
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();
        if (action.equals(Intent.ACTION_SCREEN_ON)) {
            Logcat.d(TAG, "屏幕解锁广播...");
        } else if (action.equals(Intent.ACTION_SCREEN_OFF)) {
            Logcat.d(TAG, "屏幕加锁广播...");
        }
    }

    public void registerScreenActionReceiver(Context mContext) {
        if (!isRegisterReceiver) {
            isRegisterReceiver = true;

            IntentFilter filter = new IntentFilter();
            filter.addAction(Intent.ACTION_SCREEN_OFF);
            filter.addAction(Intent.ACTION_SCREEN_ON);
            Logcat.d(TAG, "注册屏幕解锁、加锁广播接收者...");
            mContext.registerReceiver(ScreenActionReceiver.this, filter);
        }
    }

    public void unRegisterScreenActionReceiver(Context mContext) {
        if (isRegisterReceiver) {
            isRegisterReceiver = false;
            Logcat.d(TAG, "注销屏幕解锁、加锁广播接收者...");
            mContext.unregisterReceiver(ScreenActionReceiver.this);
        }
    }
}
