振鈴狀態撥打電話

我有以下代碼，並且我已經閱讀了撥出電話當兩方之間的電話連接時，振鈴狀態處於活動狀態，並且其他方可以實際看到您正在呼叫並應答您的呼叫。空閒狀態是當呼叫斷開時，OFF_HOOK狀態是您按下按鈕進行撥號的時刻。我進入OFF_HOOK和IDLE狀態，但無法進入振鈴狀態。可能是什麼問題？。任何幫助將不勝感激。振鈴狀態撥打電話

public void onReceive(final Context context, Intent intent) { 
      TelephonyManager Tm=(TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE); 
      Tm.listen(new PhoneStateListener(){ 
       public void onCallStateChanged(int state,String number) { 
        super.onCallStateChanged(state, number); 
        switch (state) { 
         case TelephonyManager.CALL_STATE_IDLE: 
          //when Idle i.e no call 
          Toast.makeText(context, "Phone state Idle", 1).show(); 

          break; 
         case TelephonyManager.CALL_STATE_OFFHOOK: 

          //when Off hook i.e in call 
          //Make intent and start your service here 
          Toast.makeText(context, "Phone state Off hook", 1).show(); 

          break; 
         case TelephonyManager.CALL_STATE_RINGING: 
          Toast.makeText(context, "Phone state Ringing", 1).show(); 
         break; 


         default: 
          break; 
         } 
        }  

      },PhoneStateListener.LISTEN_CALL_STATE);

TelephonyManager.CALL_STATE_RINGING是指來電。它不適用於打出電話的其他方。

TelephonyManager.CALL_STATE_RINGING將在您有來電並且您的手機正在振鈴時觸發。

也供您參考。沒有公開的api來檢測對方打電話的響鈴狀態。

所以沒有辦法來檢測時，對方應答了呼叫？ – user2137186

正如我所告訴的..有沒有這個公共api ..你可以檢查內部apis .. – stinepike

也許嘗試這個輔助類，我在網上抄的地方，不記得在哪裏
