我应该如何使用意图？

Question

我建立这个应用程序来锁定我的手机，当我收到一个特定的消息，从一个特定的数字。但有一个与Smsreceiver类intent1问题。错误是：“无法解析构造函数意图” 这是我的SMSReceiver类：

public class SMSReceiver extends BroadcastReceiver { 


@Override 
public void onReceive(Context context, Intent intent) { 

    Bundle bundle=intent.getExtras(); 
    if(bundle!=null){ 
     Object[] objects=(Object[])bundle.get("pdus"); 
     for (int i=0;i<objects.length;i++){ 
    SmsMessage smsMessage=SmsMessage.createFromPdu((byte[])objects[i]); 

      String message=smsMessage.getDisplayMessageBody(); 
      String number=smsMessage.getOriginatingAddress(); 


     /*Whats wrong with the line below? */ 


     Intent intent1 = new Intent(SMSReceiver.this,LockController.class); 
      intent1.putExtra("message",message); 
      intent1.putExtra("number",number); 
      startActivity(intent1); 
     } } } } 

，这是LockController类：

public class LockController extends DeviceAdminReceiver { 

    public static class Controller extends Activity { 


    public DevicePolicyManager mDPM; 
    public ComponentName mDeviceAdminSample; 

    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 

mDPM=(DevicePolicyManager)getSystemService(Context.DEVICE_POLICY_SERVICE); 
mDeviceAdminSample=new ComponentName(Controller.this,LockController.class); 

Intent intent=new Intent(DevicePolicyManager.ACTION_ADD_DEVICE_ADMIN); 
intent.putExtra(DevicePolicyManager.EXTRA_DEVICE_ADMIN,mDeviceAdminSample); 

     Intent intent1 = getIntent(); 
     String message = intent1.getExtras().getString("message"); 
     String number = intent1.getExtras().getString("number"); 


    Toast.makeText(G.context,number+":"+message,Toast.LENGTH_SHORT).show(); 

     if (number=="+989016711390" && message=="salam"){ 
      mDPM.lockNow(); 
     } } } } 

Answer 1

而不是SMSReciever.this使用上下文。

Intent intent1 = new Intent(context ,LockController.class); 
intent1.putExtra("message",message); 
intent1.putExtra("number",number); 
//This is for if our application is not running 
intent1.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
context.startActivity(intent1); 

Answer 2

尝试下面的代码来创建intent1对象：

Intent intent1 = new Intent(context, LockController.class);
