我需要做一個活動，允許用戶點擊getLocation按鈕，該按鈕又根據可能性分數返回地點列表。來自FindCurrentPlaceResponse的響應返回20個項目，我希望它們以列表或卡片視圖的形式出現，用戶最終從中選擇最合適的位置。如何使響應返回可放入可點擊列表中的各個位置？我已經遵循并完全使用谷歌地點文檔 https://github.com/googlemaps/android-places-demos 我的活動這是文檔中將列表轉換為單個字符串的確切代碼@RequiresPermission(allOf = {ACCESS_FINE_LOCATION, ACCESS_WIFI_STATE})private void findCurrentPlaceWithPermissions() {setLoading(true); FindCurrentPlaceRequest currentPlaceRequest = FindCurrentPlaceRequest.newInstance(getPlaceFields()); Task<FindCurrentPlaceResponse> currentPlaceTask = placesClient.findCurrentPlace(currentPlaceRequest); currentPlaceTask.addOnSuccessListener( (response) -> responseView.setText(StringUtil.stringify(response, isDisplayRawResultsChecked()))); currentPlaceTask.addOnFailureListener( (exception) -> { exception.printStackTrace(); responseView.setText(exception.getMessage()); }); currentPlaceTask.addOnCompleteListener(task -> setLoading(false)); }

字符串化就是這樣做的?；貞旧硪呀浭恰盎貞?。你可能需要一個帶有回調的接口才能將結果添加到磁貼列表中。
// The callback interface
interface MyCallback {
void callbackCall(List<String> response);
}
// The class that takes the callback
class Worker {
MyCallback callback;
void onEvent(List<String> response) {
callback.callbackCall(response);
}
}
// Option 1: MainActivity or where the list is
class Callback implements MyCallback {
void callbackCall() {
// callback code goes here
// update your adaptor
}
}
worker.callback = new Callback();
// Option 2:
worker.callback = new MyCallback() {
void callbackCall(List<String> results ) {
// callback code goes here
}
};
