如何获得使用 Google 地方信息自动填充功能的意向?

Question

你能告诉我我需要做什么才能让我的意图起作用吗？当用户单击mEditInit时，将显示地点下拉菜单。

当用户单击菜单中的位置时，我想将其发送回mEditInit

我以前使用过意图，但在这种情况下不起作用。

public class MyActivity extends AppCompatActivity  {
String stuff;
private EditText mEditInit;
public static final int AUTOCOMPLETE_REQUEST_CODE = 1;

@Override
protected void onCreate (Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_my);
mEditInit = (EditText) findViewById(R.id.edit_message);
mEditInit.setX(0);
mEditInit.setY(250);
//Get the bundle
Bundle bundle = getIntent().getExtras();

if (stuff != null && !stuff.isEmpty())
//Extract the data…
{ stuff = bundle.getString("stuff");
mEditInit.setText(stuff);
}
Places.initialize(this, getString(R.string.places_api_key));
mEditInit.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(MyActivity.this, "bowwow", Toast.LENGTH_SHORT).show();
List<Place.Field> fields = Arrays.asList(Place.Field.ID, Place.Field.NAME);
// Start the autocomplete intent.
Intent intent = new Autocomplete.IntentBuilder(AutocompleteActivityMode.OVERLAY, fields).build(MyActivity.this);
startActivityForResult(intent, AUTOCOMPLETE_REQUEST_CODE);
//setResult(RESULT_OK, intent);
}
});
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == AUTOCOMPLETE_REQUEST_CODE) {
if (resultCode == RESULT_OK) {
Place place = Autocomplete.getPlaceFromIntent(data);
//Toast.makeText(MyActivity.this, place.getName(), Toast.LENGTH_SHORT).show();
Toast.makeText(MyActivity.this, place.getName(), Toast.LENGTH_SHORT).show();
Intent i = new Intent(this, MyActivity.class);
String getrec= place.getName();
//Create the bundle
Bundle bundle = new Bundle();
//Add your data to bundle
bundle.putString("stuff", getrec);
//Add the bundle to the intent
i.putExtras(bundle);
// Log.i(TAG, "Place: " + place.getName() + ", " + place.getId());
} else if (resultCode == AutocompleteActivity.RESULT_ERROR) {
// TODO: Handle the error.
Status status = Autocomplete.getStatusFromIntent(data);
// Log.i(TAG, status.getStatusMessage());
} else if (resultCode == RESULT_CANCELED) {
// The user canceled the operation.
}
//  super.onActivityResult(requestCode, resultCode, data);
}
}
}

在您的onActivityResult方法中，您不需要任何额外的内容。

只需在EditText上调用方法setText()：

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == AUTOCOMPLETE_REQUEST_CODE) {
if (resultCode == RESULT_OK) {
Place place = Autocomplete.getPlaceFromIntent(data);
//Toast.makeText(MyActivity.this, place.getName(), Toast.LENGTH_SHORT).show();
mEditInit.setText(place.getName());
} else if (resultCode == AutocompleteActivity.RESULT_ERROR) {
// TODO: Handle the error.
Status status = Autocomplete.getStatusFromIntent(data);
// Log.i(TAG, status.getStatusMessage());
} else if (resultCode == RESULT_CANCELED) {
// The user canceled the operation.
}
//  super.onActivityResult(requestCode, resultCode, data);
}
}
