问题

我正在尝试在我的应用程序中使用Google Places Android库，它运行得非常好。问题在于，当用户在“AutocompleteSupportFragment”中选择地点/地址或按返回按钮时，会结束当前的活动并返回到主活动。

我的活动是作为“Receiver”的结果打开的活动。

活动调用的代码
```java
Intent requestDriverIntent = new Intent(receiverContext, RequestDeliveryActivity.class);
requestDriverIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); // 广播接收器所需
requestDriverIntent.putExtra("line", lineItemId);
requestDriverIntent.putExtra("order", orderId);
receiverContext.startActivity(requestDriverIntent);

以下是我如何使用Places响应

private class AddressSelectionListener implements PlaceSelectionListener {
    @Override
    public void onPlaceSelected(@NonNull Place place) {
      deliveryAddress = place.getAddress();
      deliveryLat = place.getLatLng().latitude;
      deliveryLng = place.getLatLng().longitude;
    }

    @Override
    public void onError(@NonNull Status status) {
        errorAlertDialog.show();
    }
}

I&#39;m trying to use Google Places android lib in my app, It works very well. The problem, when user select the place/address in `AutocompleteSupportFragment` or when press the back button, this finish my current activity and returns to the main activity.

My activity is an activity that opens as result of a `Receiver`.

Code of activity invocation
```java
Intent requestDriverIntent = new Intent(receiverContext, RequestDeliveryActivity.class);
requestDriverIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); // required by the app who broadcast
requestDriverIntent.putExtra(&quot;line&quot;, lineItemId);
requestDriverIntent.putExtra(&quot;order&quot;, orderId);
receiverContext.startActivity(requestDriverIntent);

And here how I use the Places response

private class AddressSelectionListener implements PlaceSelectionListener {
    @Override
    public void onPlaceSelected(@NonNull Place place) {
      deliveryAddress = place.getAddress();
      deliveryLat = place.getLatLng().latitude;
      deliveryLng = place.getLatLng().longitude;
    }

    @Override
    public void onError(@NonNull Status status) {
        errorAlertDialog.show();
    }
  }

在你的 RequestDeliveryActivity 中重写 onBackPressed 方法，不要调用 super，而是留空（Activity 不会在返回键按下时关闭），或者根据需要启动另一个 Activity，然后调用 finish(); 来关闭当前的 Activity。

    @Override
    public void onBackPressed() {
        // 留空或者启动新的操作
    }

@Override
public void onBackPressed() {
    // leave empty or start smth new
}

使用重写 onBackPressed() 方法在活动中。

尝试这样做：

@Override
public void onBackPressed() {
    finish();
}

@Override
public void onBackPressed() {
    finish();
}

好的，我找到了错误。我只是从清单文件中移除了 android:noHistory="true"。
