在 Fragment 中使用 GoogleApiClient 执行 PendingTransactions 的递归条目

Question

我正在尝试在我的应用中使用 Place Autocomplete API。我有一个主要的Activity。我有一个Fragment，它是MainActivity 的一部分。在OnViewCreated() 这个Fragment.

 private void rebuildGoogleApiClient() {
    // When we build the GoogleApiClient we specify where connected and connection failed
    // callbacks should be returned and which Google APIs our app uses.
    mGoogleApiClient = new GoogleApiClient.Builder(getActivity())
            .enableAutoManage(activity, 0 /* clientId */, this)
            .addConnectionCallbacks(this)
            .addApi(Places.GEO_DATA_API)
            .build();
}

堆栈跟踪：

我们将不胜感激。

Answer 1

不要在onViewCreated() 中调用rebuildGoogleApiClient()，而是尝试在片段的onActivityCreated() 方法中调用它。

有关片段生命周期的更多信息，请参阅http://developer.android.com/reference/android/app/Fragment.html#Lifecycle。

如果这仍然不起作用，您可以删除 enableAutoManage(...) 并在 GoogleApiClient 实例上显式调用 connect() 和 disconnect()。

详情请见https://developers.google.com/places/android/start#connect-client。

这有帮助吗？

为我工作：

public class TestActivity extends Fragment {

@Override
public void onActivityCreated(Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);
    mGoogleApiClient = new GoogleApiClient.Builder(getActivity())
            .addApi(Places.GEO_DATA_API)
            .build();
}

@Override
public void onStart() {
    super.onStart();
    mGoogleApiClient.connect();
}

@Override
public void onStop() {
    super.onStop();
    mGoogleApiClient.disconnect();
}
}
