如何检测android中的拨出呼叫到特定的号码？

Question

我们可以轻松检测用户是否正在通话。我需要添加一个过滤器，即用户是否对特定号码进行了任何调用。有可能吗？

Answer 1

创建一个BroadcastReceiver类并在清单文件中注册它。并检查拨出电话意图。

前：

public class DialCallListener extends BroadcastReceiver {
private static final String OUTGOING_CALL_INTENT = "android.intent.action.NEW_OUTGOING_CALL";

//Inside onReceive method, check the call state
@Override
public void onReceive(Context context, Intent intent) {
    int callState = TelephonyManager.CALL_STATE_IDLE;
    try {
        String stateStr = intent.getExtras().getString(TelephonyManager.EXTRA_STATE);

      //Check if call state is OFFHook
      if (stateStr.equals(TelephonyManager.EXTRA_STATE_OFFHOOK)) {
            callState = TelephonyManager.CALL_STATE_OFFHOOK;

            //Call the listener interface when call state change. And handle this state change inside PhoneListener class.
    MyPhoneStateListener PhoneListener = new MyPhoneStateListener(context);
    PhoneListener.onCallStateChanged(callState, number);
      }

     }catch (Exception err) {
        err.printStackTrace();
    }

} }

//如果呼叫状态改变（拨打任何号码）

，现在创建一个监听器

private class MyPhoneStateListener extends PhoneStateListener implements ICallReceiver {


public void onCallStateChanged(int state, String dialing_number) {

         switch (state) {
         case TelephonyManager.CALL_STATE_OFFHOOK:
                //Handle Call dial
                mPresenter.handleCallOffHook(incomingNumber);
                break;
         }

} }
