推荐答案

首先，你必须设置通过进入手动设置模式锁定。
那么你就可以得到低于使用code的事件。

First you have to setup the Pattern Lock by going into setting manually . then you can receive the events using code below . `

import android.app.admin.DeviceAdminReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
import android.widget.Toast;


public class DemoDeviceAdminReceiver extends DeviceAdminReceiver {
        static final String TAG = "DemoDeviceAdminReceiver";

        /** Called when this application is approved to be a device administrator. */
        @Override
        public void onEnabled(Context context, Intent intent) {
                super.onEnabled(context, intent);
                Toast.makeText(context, R.string.device_admin_enabled,
                                Toast.LENGTH_LONG).show();
                Log.d(TAG, "onEnabled");
        }

        /** Called when this application is no longer the device administrator. */
        @Override
        public void onDisabled(Context context, Intent intent) {
                super.onDisabled(context, intent);
                Toast.makeText(context, R.string.device_admin_disabled,
                                Toast.LENGTH_LONG).show();
                Log.d(TAG, "onDisabled");
        }

        @Override
        public void onPasswordChanged(Context context, Intent intent) {
                super.onPasswordChanged(context, intent);
                Log.d(TAG, "onPasswordChanged");
        }

        @Override
        public void onPasswordFailed(Context context, Intent intent) {
                super.onPasswordFailed(context, intent);
                Log.d(TAG, "onPasswordFailed");
        }

        @Override
        public void onPasswordSucceeded(Context context, Intent intent) {
                super.onPasswordSucceeded(context, intent);
                Log.d(TAG, "onPasswordSucceeded");
        }



}
