【问题描述】：

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。

【解决方案1】：

将依赖项添加到 yourbuild.gradle（将 <version-number> 替换为您想要的版本，例如，Gradle, Please）：

compile "com.google.android.gms:play-services-places:<version-number>"

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"/>

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;

        }
    }
}

最后，这是打开PlacePicker的代码

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();
}

在 Button clicklistner 或您要打开 PlacePicker 的地方调用此方法：

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();
        }
    }

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));

            }
        }
    }
