android - 需要在 PhoneStateListener 中调用一个 Activity

Question

我需要在电话状态从响铃变为空闲时调用一个 Activity 。但它说 构造函数 Intent(MyPhoneStateListener, Class) 未定义。如何调用 Activity 。

    public class MyPhoneStateListener extends PhoneStateListener {
        //static String org="";

        public void onCallStateChanged(int state,String incomingNumber){
              switch(state){
                case TelephonyManager.CALL_STATE_IDLE:
                  Log.d("DEBUG", "IDLE");
                 // MissedCall ms=new MissedCall();

                 Intent missintent=new Intent(this,MissedCall.class);
                 startActivity(missintent);

                break;
                case TelephonyManager.CALL_STATE_OFFHOOK:
                  Log.d("DEBUG", "OFFHOOK");
                break;
                case TelephonyManager.CALL_STATE_RINGING:
                  Log.d("DEBUG", "RINGING");
                break;
                }
              }
    }

您可以这样调用 Activity :

Intent missintent= new Intent(context, MissedCall.class);
missintent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(missintent);
