java - 如何为android 3.0以上版本定义广播接收器？

Question

这是我的phonestate 类，我在其中检查手机状态更改

public class CustomPhoneStateListener extends PhoneStateListener 
{

  private static final String TAG = "CustomPhoneStateListener";

  Context context; //Context to make Toast if required 
  public CustomPhoneStateListener(Context context) 
  {
    super();
    this.context = context;
  }
  public void onCallStateChange(int state, String incomingNumber)
  {

        Log.v(TAG, "WE ARE INSIDE!!!!!!!!!!!");
        Log.v(TAG, incomingNumber);

        switch(state){
                case TelephonyManager.CALL_STATE_RINGING:
                        Log.d(TAG, "RINGING");
                        Toast.makeText(context, "Incoming number :"+incomingNumber, Toast.LENGTH_LONG).show();
                        break;
        }        }

这是我的广播接收器类，其中与广播连接

    public class CustomBroadcastReceiver extends BroadcastReceiver {

private static final String TAG = "CustomBroadcastReceiver";

@Override
public void onReceive(Context context, Intent intent) {
        Log.v(TAG, "WE ARE INSIDE!!!!!!!!!!!");
    TelephonyManager telephony = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);
        CustomPhoneStateListener customPhoneListener = new CustomPhoneStateListener();

    telephony.listen(customPhoneListener, PhoneStateListener.LISTEN_CALL_STATE);


    Bundle bundle = intent.getExtras();
    String phoneNr= bundle.getString("incoming_number");
        Log.v(TAG, "phoneNr: "+phoneNr);
}

我有一些在java文件中定义 Intent 的想法，bcz Android版本 3.0以上的需求 定义 Intent 。

Intent intent = new Intent();
      intent.setAction("com.example.SendBroadcast");
      intent.addFlags(Intent.FLAG_INCLUDE_STOPPED_PACKAGES);
      sendBroadcast(intent);

我不知道如何以及在哪里定义这部分代码是否在 广播类或phonestate类。

显然!!将此代码调用到自定义 PhoneStateListener 类中，否则永远不会调用广播。
