android - 需要在PhoneStateListener中调用 Activity

当电话状态从振铃转为空闲时，我需要打电话给活动。但是它说构造函数Intent（MyPhoneStateListener，Class）是未定义的。如何调用活动。

    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;
                }
              }
    }

最佳答案

您可以这样调用活动：

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