在android上得到确认电话回答

Question

我正在处理android手机号码，您可以知道是否拨打了电话，即确认电话被接听。使用以下代码进行调用:

Intent callIntent = new Intent (Intent.ACTION_CALL, Uri.parse (number));
startActivity (callIntent);

当你结束对我的应用程序的呼叫时，这时我想知道呼叫是否被应答，以及呼叫的持续时间

是的，你可以，为此你需要创建BroadCastReceiver与意图例如

 <receiver android:name=".broadcast.DontMissReceiver" >
            <intent-filter>
                <action android:name="android.intent.action.PHONE_STATE" />
            </intent-filter>
  </receiver>

，然后是Receiver

    @Override
    public void onReceive(final Context context, Intent intent) {
        String action = intent.getAction();
        if (action.equalsIgnoreCase(PHONE_ACTION)) {
            this.receivePhoneCall(context, intent);
            }
     }
     private void receivePhoneCall(Context context, Intent intent) {
        String curState = intent.getExtras().getString("state");
        if (curState.equalsIgnoreCase("RINGING")) {
        } else
        if (curState.equalsIgnoreCase("IDLE") && state.length() > 0) {
            if (!state.equalsIgnoreCase("OFFHOOK")) {
            }
        }
    }
