如何檢測傳出呼叫連接android

Question

如何檢測傳出呼叫連接。我的代碼如下，但有incomingcall若在該得到，如果（intent.getStringExtra（TelephonyManager.EXTRA_STATE）.equals（TelephonyManager.EXTRA_STATE_RINGING））

時，沒有活動就在這個

得到否則如果（intent.getStringExtra（TelephonyManager.EXTRA_STATE）.equals（TelephonyManager.EXTRA_STATE_IDLE））

當incomingcall是回答它會得到這個和它的呼叫它會得到這個。

否則，如果（intent.getStringExtra（TelephonyManager.EXTRA_STATE）.equals（TelephonyManager.EXTRA_STATE_OFFHOOK））

，現在當outgoingcall它的狀態是摘機我怎麼能知道我的outgoingcall連接時。

謝謝

@Override 
public void onReceive(Context context, Intent intent) { 
    // TODO: This method is called when the BroadcastReceiver is receiving 
    // an Intent broadcast. 
    if(intent.getStringExtra(TelephonyManager.EXTRA_STATE).equals(TelephonyManager.EXTRA_STATE_RINGING)){ 
     String incomingNumber = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER); 
     Toast.makeText(context, "Call From : " + incomingNumber, Toast.LENGTH_LONG).show(); 

    } 
    else if (intent.getStringExtra(TelephonyManager.EXTRA_STATE).equals(TelephonyManager.EXTRA_STATE_IDLE)){ 
     Toast.makeText(context,TelephonyManager.EXTRA_STATE_IDLE,Toast.LENGTH_LONG).show(); 
    } 
    else if (intent.getStringExtra(TelephonyManager.EXTRA_STATE).equals(TelephonyManager.EXTRA_STATE_OFFHOOK)){ 
     Toast.makeText(context,TelephonyManager.EXTRA_STATE_OFFHOOK,Toast.LENGTH_LONG).show(); 
    } 
}

在Android清單文件中添加這一點。聲明廣播接收器。

<receiver 
     android:name=".OutCallLogger" 
     android:enabled="true" 
     android:exported="true" > 
      <intent-filter> 
       <action android:name="android.intent.action.PRECISE_CALL_STATE" /> 
       <action android:name="android.intent.action.NEW_OUTGOING_CALL" /> 
      </intent-filter> 
    </receiver> 

在Android清單文件中添加以下權限。

<uses-permission android:name="android.permission.READ_PHONE_STATE" /> 
<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS" /> 
<uses-permission android:name="android.permission.READ_PRECISE_PHONE_STATE" /> 

也在清單文件中添加此行。

<uses-feature android:name="android.hardware.telephony"> 
</uses-feature> 

這是您的班級，將用於獲取撥出呼叫的精確呼叫狀態。
