java - 放置选择器自动关闭

Question

我正在 Android 中制作一个简单的地点选择器程序，问题是当我单击按钮时，地点选择器会打开并在 2 - 3 秒后自动关闭...请帮忙!

public class MainActivity extends ActionBarActivity implements View.OnClickListener {

    Button b;
    private static final int PLACE_PICKER_REQUEST = 1;
    private static final LatLngBounds BOUNDS_MOUNTAIN_VIEW = new LatLngBounds(
            new LatLng(37.398160, -122.180831), new LatLng(37.430610, -121.972090));


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        b = (Button) findViewById((R.id.bOpenMap));
        b.setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {
            try {
                PlacePicker.IntentBuilder intentBuilder =
                        new PlacePicker.IntentBuilder();
                intentBuilder.setLatLngBounds(BOUNDS_MOUNTAIN_VIEW);
                Intent intent = intentBuilder.build(getApplicationContext());
                startActivityForResult(intent, PLACE_PICKER_REQUEST);
            } catch (GooglePlayServicesRepairableException e) {
                e.printStackTrace();
            } catch (GooglePlayServicesNotAvailableException e) {
                e.printStackTrace();
            }

        if (requestCode == PLACE_PICKER_REQUEST) {
            if (resultCode == RESULT_OK) {
                Place place = PlacePicker.getPlace(data, this);
                String toastMsg = String.format("Place: %s", place.getName());
                Toast.makeText(this, toastMsg, Toast.LENGTH_LONG).show();
            }
        }
    }
}

我运行了您的代码和配置，并看到了与您所看到的相同的行为。

将您的配置与我正在使用的配置进行比较后，我意识到问题在于您的 AndroidManifest.xml 中，您需要更改以下内容:

android:name="com.google.android.maps.v2.API_KEY"

对此:

android:name="com.google.android.geo.API_KEY"

我回去对这两种配置进行了多次测试，只是为了确保这就是导致您出现问题的原因。使用第一个配置，PlacePicker 每次都会立即关闭。

使用com.google.android.geo.API_KEY，每次都能完美运行。

这也是the documentation说明您需要使用 Places API。

使用您的代码进行测试的结果，以及使其工作所需的一项修改:
