android - android中调用结束过程的 Action 事件

Question

我正在开发一个应用程序，我想在其中跟踪拨出电话及其持续时间。例如，如果手机用户调用电话，我使用了 Intent.ACTION_NEW_OUTGOING_CALL。*当他挂断电话时，要实现什么操作？*我引用了所有教程，他们建议使用设备调用日志 URI。但我想在广播接收器中执行此操作。提前致谢。

  public class MyCallReceiver extends BroadcastReceiver{
      public void onReceive(Context context, Intent intent) {

    if (intent.getAction().equals(Intent.ACTION_NEW_OUTGOING_CALL)) {

        String number = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);

       }    

    }
  }

Answer 1

试试这个:

Boolean wasnumberdialed=false;
Boolean callpicked=false;

//if dialed below is called
if (intent.getAction().equals(Intent.ACTION_NEW_OUTGOING_CALL)) {
        String number = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
        wasnumberdialed=true;
}

//if the call is received by the recipient then this is executed and its an 
//outgoing call,(wasnumberdialed is set to true only for outgoing calls) we 
//need to  ignore incoming calls. If wedont check this an incoming call 
//would also execute this.
if (intent.getAction().equals(Intent.CALL_STATE_OFFHOOK && wasnumberdialed)) {
        //start your timer to count the time of call
        //long start_time = System.currentTimeMillis();
        callpicked=true;
 }

//after the call is disconnected and was received which is an outgoing call below is 
//executed
if (intent.getAction().equals(Intent.EXTRA_STATE_IDLE && callpicked)) {
        //end your timer here
        //long end_time = System.currentTimeMillis();
}

Log.v("myapp","Total call time is "+TimeUnit.MILLISECONDS.toMinutes(end_time-start_time)+" mins);
