Android的使用PlaceAutoCompleteActivity（谷歌Places API的） [英] Android using PlaceAutoCompleteActivity (Google Places API)
本文介绍了Android的使用PlaceAutoCompleteActivity（谷歌Places API的）的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我已经我与 PlaceAutoCompelteActivity 遇到的问题的一个很简单的例子。我的地图上会显示在屏幕上，与上面的两个文本搜索栏一起。问题是，一旦我在TextView的点击，键盘会弹出，光标将在TextView中闪烁（如预期），但之后我键入的第一个字母（如果我快速输入我可以得到2个字母）时，键盘就会消失，搜索框会一片空白，光标就会消失（返回到pclicked状态的$ p $）。下面是该文档的链接：

在code为简单的活动和XML文件是如下：

解决方案
您可能需要插入自己的API密钥（如果你还没有这样做的话），可以通过谷歌开发者控制台进行收购。
详细信息在这里：

此外，在谷歌开发者控制台，添加谷歌Places API所为启用API的名单在您的项目。
I have made a very simple example of the issue I am having with the PlaceAutoCompelteActivity. My map will show on the screen, along with 2 text search bars on top. The issue is that once I click in the textview, a keyboard will come up and a cursor will blink in the textview (as expected), however after I type the first letter (if i type quickly I can get 2 letters in), the keyboard will go away and the search box will blank out and the cursor will go away (return to the preclicked on state.) Here is a link to the documentation:
https://developers.google.com/places/android-api/autocomplete?hl=en
The code for the simple activity and the xml file are below:
java activity:
package com.blah.android.backseatbuddy;
import android.support.v4.app.FragmentActivity;
import android.os.Bundle;
import android.util.Log;
import com.google.android.gms.common.api.Status;
import com.google.android.gms.location.places.Place;
import com.google.android.gms.location.places.ui.PlaceAutocompleteFragment;
import com.google.android.gms.location.places.ui.PlaceSelectionListener;
import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.OnMapReadyCallback;
import com.google.android.gms.maps.SupportMapFragment;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;
public class RouteActivity extends FragmentActivity implements OnMapReadyCallback {
private GoogleMap mMap;
// private EditText beginningDestination;
// private EditText endingDestination;
PlaceAutocompleteFragment beginningDestination;
PlaceAutocompleteFragment endingDestination;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_route);
beginningDestination = (PlaceAutocompleteFragment) getFragmentManager().findFragmentById(R.id.beginning_destination);
beginningDestination.setOnPlaceSelectedListener(new PlaceSelectionListener() {
@Override
public void onPlaceSelected(Place place) {
// TODO: Get info about the selected place.
Log.i("beginningDestination ", "Place: " + place.getName());
}
@Override
public void onError(Status status) {
// TODO: Handle the error.
Log.i("beginningDestination ", "An error occurred: " + status);
}
});
endingDestination = (PlaceAutocompleteFragment) getFragmentManager().findFragmentById(R.id.ending_destination);
endingDestination.setOnPlaceSelectedListener(new PlaceSelectionListener() {
@Override
public void onPlaceSelected(Place place) {
// TODO: Get info about the selected place.
Log.i("endingDestination ", "Place: " + place.getName());
}
@Override
public void onError(Status status) {
// TODO: Handle the error.
Log.i("endingDestination ", "An error occurred: " + status);
}
});
// beginningDestination = (EditText) findViewById(R.id.beginning_destination);
// endingDestination = (EditText) findViewById(R.id.ending_destination);
// Obtain the SupportMapFragment and get notified when the map is ready to be used.
SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
}
@Override
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
// Add a marker in Sydney and move the camera
LatLng sydney = new LatLng(-34, 151);
mMap.addMarker(new MarkerOptions().position(sydney).title("Marker in Sydney"));
mMap.moveCamera(CameraUpdateFactory.newLatLng(sydney));
}
}
and xml layout file:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout android:id="@+id/relativeLayoutFragment"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<fragment
android:id="@+id/beginning_destination"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:name="com.google.android.gms.location.places.ui.PlaceAutocompleteFragment"
/>
<fragment
android:id="@+id/ending_destination"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:name="com.google.android.gms.location.places.ui.PlaceAutocompleteFragment"
/>
<fragment
android:id="@+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:map="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.greg.android.backseatbuddy.RouteActivity"/>
</LinearLayout>
解决方案
You may need to insert your own API key (if you haven't done so already) that can be acquired through the Google developers console. Details here: https://developers.google.com/places/android-api/signup?hl=en Also, in the Google developers console, add Google Places API to the list of enabled API's in your project.
