Google Place Picker Android Studio
提问by Justin Luna
Does anyone know how to implement Google Place Picker API in Android Studio? Tried tutorials, unsuccessful. I want a working AutoComplete Text Field that has places show up and when you click on the place it will display in the Google Map Fragment.
有谁知道如何在 Android Studio 中实现 Google Place Picker API？试过教程，不成功。我想要一个显示位置的工作自动完成文本字段，当您单击该位置时，它将显示在 Google 地图片段中。

Add the dependency to yourbuild.gradle:
将依赖项添加到您的build.gradle：
compile "com.google.android.gms:play-services-places:10.2.0"
Add your key to your AndroidManifest.xml:
将您的密钥添加到您的AndroidManifest.xml：
<meta-data
android:name="com.google.android.geo.API_KEY"
android:value="@string/map_api_key"/>
Your Activity/Fragment needs these attributes and methods:
您的 Activity/Fragment 需要这些属性和方法：
private final static int PLACE_PICKER_REQUEST = 999;
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
checkPermissionOnActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
switch (requestCode){
case PLACE_PICKER_REQUEST:
Place place = PlacePicker.getPlace(this, data);
String placeName = String.format("Place: %s", place.getName());
double latitude = place.getLatLng().latitude;
double longitude = place.getLatLng().longitude;
}
}
}
finally, this is the code to open a PlacePicker
最后，这是打开一个的代码 PlacePicker
PlacePicker.IntentBuilder builder = new PlacePicker.IntentBuilder();
try {
// for activty
startActivityForResult(builder.build(this), PLACE_PICKER_REQUEST);
// for fragment
//startActivityForResult(builder.build(getActivity()), PLACE_PICKER_REQUEST);
} catch (GooglePlayServicesRepairableException e) {
e.printStackTrace();
} catch (GooglePlayServicesNotAvailableException e) {
e.printStackTrace();
}

call this method on Button clicklistner or where you want to open PlacePicker:
在 Button clicklistner 或要打开 PlacePicker 的位置调用此方法：
private final static int PLACE_PICKER_REQUEST = 111;
private void openPlacePicker() {
PlacePicker.IntentBuilder builder = new PlacePicker.IntentBuilder();
try {
// for activty
startActivityForResult(builder.build(this), PLACE_PICKER_REQUEST);
// for fragment
//startActivityForResult(builder.build(getActivity()), PLACE_PICKER_REQUEST);
} catch (GooglePlayServicesRepairableException e) {
e.printStackTrace();
} catch (GooglePlayServicesNotAvailableException e) {
e.printStackTrace();
}
}
and fetch the result onActivityResult:
并在 ActivityResult 上获取结果：
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
switch (requestCode) {
case PLACE_PICKER_REQUEST:
Place place = PlacePicker.getPlace(this, data);
String placeName = String.format("Place: %s", place.getName());
double latitude = place.getLatLng().latitude;
double longitude = place.getLatLng().longitude;
LatLng coordinate = new LatLng(latitude, longitude);
MarkerOptions markerOptions = new MarkerOptions();
markerOptions.position(coordinate);
markerOptions.title(placeName); //Here Total Address is address which you want to show on marker
mGoogleMap.clear();
markerOptions.icon(
BitmapDescriptorFactory
.defaultMarker(BitmapDescriptorFactory.HUE_BLUE));
markerOptions.getPosition();
mCurrLocationMarker = mGoogleMap.addMarker(markerOptions);
mGoogleMap.moveCamera(CameraUpdateFactory.newLatLng(coordinate));
mGoogleMap.animateCamera(CameraUpdateFactory.zoomTo(15));
}
}
}
