Google最近更新了他们的Places SDK for android，所以现在我也在更新我的代码。我正在尝试使用AutocompleteSupportFragment来允许用户设置他们的地址。
这是我的代码：
mAddressEditText = (AutocompleteSupportFragment) getSupportFragmentManager().findFragmentById(R.id.address);
mAddressEditText.setPlaceFields(Arrays.asList(Place.Field.ADDRESS, Place.Field.LAT_LNG));
mAddressEditText.setHint("Address");
mAddressEditText.setText("Test1"); // Works fine at the beginning, disappears after selecting a place and shows only the hint
mAddressEditText.setOnPlaceSelectedListener(new PlaceSelectionListener() {
@Override
public void onPlaceSelected(Place place) {
Log.d(TAG, "Place Selected");
// Other Stuff
mAddressEditText.setText("Test2"); // Doesn't Work, all I can see is the hint
mAddressEditText.setText(place.getAddress()); // Doesn't Work, all I can see is the hint
}
@Override
public void onError(Status status) {
Log.e(TAG, "An error occurred: " + status);
invalidAddressDialog.show();
}
});
在之前的SDK中，片段会自动将文本设置为所选地址。这在新SDK中不起作用（不确定是否有意）。所以我试图手动设置它。正如您在我的代码中的注释中所看到的，使用setText在侦听器之外工作正常。在听众里面他们没有。
我做错了什么或这是一个错误？
编辑：这么久，我仍然无法得到适当的解决方案。要非常清楚，我可以从片段中正确地获取地址，唯一不起作用的是setText。
但是，由于一些答案表明他们没有遇到同样的问题，我开始认为它可能与我正在使用的库版本有关？
这些是我在build.gradle中的库：
api 'com.android.support:appcompat-v7:28.0.0'
api 'com.android.support:support-annotations:28.0.0'
api 'com.android.support:multidex:1.0.3'
api 'com.google.firebase:firebase-core:16.0.8'
api 'com.google.firebase:firebase-auth:16.2.1'
api 'com.google.firebase:firebase-firestore:18.2.0'
api 'com.google.firebase:firebase-storage:16.1.0'
api 'com.google.android.libraries.places:places:1.1.0'
setText给了我同样的问题 - 它一定是我认为的错误。但是我发现了一些提示。在onPlaceSelected中，您可以输入以下内容：
Java的
EditText etPlace = (EditText) autocompleteFragment.getView().findViewById(R.id.places_autocomplete_search_input);
etPlace.setHint(place.getAddress())
科特林
val etPlace = autocompleteFragment.view?.findViewById(R.id.places_autocomplete_search_input) as EditText
etPlace.hint = place.address
我相信这是一个错误，因为让它像这样工作是没有意义的。什么工作设置其他自动完成的文本，但不是自己的。这必须是一个错误。
这是我正在使用的代码，它工作得非常好。
对build.gradle（应用程序级别）进行一些更改
将其添加到build.gradle：
android{
...
ext {
googlePlayServicesVersion = "15.0.1"
}
}
添加这些依赖项：
dependencies {
...
//Also if you're using any firebase dependencies make sure that the are up to date
implementation 'com.google.android.gms:play-services-places:16.0.0'
implementation 'com.google.android.libraries.places:places:1.1.0'
}
apply plugin: 'com.google.gms.google-services'
在xml布局中：
<fragment
android:id="@+id/autocomplete_fragment"
android:name="com.google.android.libraries.places.widget.AutocompleteSupportFragment"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
活动中的代码：
private void initGooglePlacesApi() {
// Initialize Places.
Places.initialize(getApplicationContext(), "YOUR_API_KEY");
// Create a new Places client instance.
PlacesClient placesClient = Places.createClient(getApplicationContext());
// Initialize the AutocompleteSupportFragment.
AutocompleteSupportFragment autocompleteFragment = (AutocompleteSupportFragment)
getSupportFragmentManager().findFragmentById(R.id.autocomplete_fragment);
autocompleteFragment.setHint(getString(R.string.select_location_search_bar));
// autocompleteFragment.setLocationRestriction(RectangularBounds.newInstance(
// new LatLng(34.7006096, 19.2477876),
// new LatLng(41.7488862, 29.7296986))); //Greece bounds
autocompleteFragment.setCountry("gr");
// Specify the types of place data to return.
autocompleteFragment.setPlaceFields(Arrays.asList(Place.Field.ADDRESS, Place.Field.ADDRESS_COMPONENTS));
autocompleteFragment.setTypeFilter(TypeFilter.ADDRESS);
// Set up a PlaceSelectionListener to handle the response.
autocompleteFragment.setOnPlaceSelectedListener(new PlaceSelectionListener() {
@Override
public void onPlaceSelected(Place place) {
if(place.getAddressComponents().asList().get(0).getTypes().get(0).equalsIgnoreCase("route")){
binding.textViewLocation.setText(place.getAddress()); //Works well
location = place.getAddress();
}else{ //If user does not choose a specific place.
AndroidUtils.vibratePhone(getApplication(), 200);
TastyToast.makeText(getApplicationContext(),
getString(R.string.choose_an_address), TastyToast.DEFAULT, TastyToast.CONFUSING);
}
Log.i(TAG, "Place: " + place.getAddressComponents().asList().get(0).getTypes().get(0) + ", " + place.getId() + ", " + place.getAddress());
}
@Override
public void onError(Status status) {
Log.i(TAG, "An error occurred: " + status);
}
});
}
编辑：这是我更新的答案
# When you are using AutocompleteSupportFragment or AutocompleteActivity
# in Fragments, do this:
public class YourFragment extends Fragment {
/.../
@Override
public void onActivityResult (int requestCode,int resultCode,
@Nullable Intent data){
# AUTOCOMPLETE_REQUEST_CODE is just a unique constant, define it
if (requestCode == AUTOCOMPLETE_REQUEST_CODE) {
if (resultCode == AutocompleteActivity.RESULT_OK) {
Place place = Autocomplete.getPlaceFromIntent(data);
// when resultcode is RESULT_OK
mAddressEditText.setText(place.getName());
// Notice this line, update your editText up here
}else if (resultCode == AutocompleteActivity.RESULT_ERROR) {
Status status = Autocomplete.getStatusFromIntent(data);
// Handle error
} else if (resultCode == AutocompleteActivity.RESULT_CANCELED) {
// Handle results if canceled
}
super.onActivityResult(requestCode, resultCode, data);
}
}
/.../
}
# If you are extending AppCompatActivity, you might want to do this
# ONLY when you are already doing something in onActivityResult
public class YourActivity extends AppCompatActivity{
/.../
@Override
public void onActivityResult (int requestCode,int resultCode,@Nullable Intent data){
# your logic here.
/.../
# if you are already overriding onActivityResult,
# do not forget to put this line
super.onActivityResult(requestCode, resultCode, data);
}
/.../
}
我也遇到了这个问题。原来你无论如何都必须覆盖它并实现它，无论是使用AutocompleteSupportFragment还是AutocompleteActivity，如果你在Fragments中工作。
如果你正在使用AppCompatActivity你不必实现它，但如果你已经超越onActivityResult做某事，不要忘记调用基本方法super.onActivityResult
