打开位置服务而不导航到设置页面

Question

对于提示用户转到设置页面并启用位置服务并再次返回的传统方法,我注意到在一些最新的应用程序中执行相同操作的更简单方法.

参考下面的截图,它会提示一个对话框,用户只需点击一下鼠标,使定位服务,它在这些应用程序的工作原理.

我怎样才能实现同样的目标？

Answer 1

此对话框由Google Play服务中提供的LocationSettingsRequest.Builder创建.

您需要为您的应用添加依赖项build.gradle:

compile 'com.google.android.gms:play-services-location:10.0.1'

然后你可以使用这个最小的例子:

private void displayLocationSettingsRequest(Context context) {
    GoogleApiClient googleApiClient = new GoogleApiClient.Builder(context)
            .addApi(LocationServices.API).build();
    googleApiClient.connect();

    LocationRequest locationRequest = LocationRequest.create();
    locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
    locationRequest.setInterval(10000);
    locationRequest.setFastestInterval(10000 / 2);

    LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder().addLocationRequest(locationRequest);
    builder.setAlwaysShow(true);

    PendingResult<LocationSettingsResult> result = LocationServices.SettingsApi.checkLocationSettings(googleApiClient, builder.build());
    result.setResultCallback(new ResultCallback<LocationSettingsResult>() {
        @Override
        public void onResult(LocationSettingsResult result) {
            final Status status = result.getStatus();
            switch (status.getStatusCode()) {
                case LocationSettingsStatusCodes.SUCCESS:
                    Log.i(TAG, "All location settings are satisfied.");
                    break;
                case LocationSettingsStatusCodes.RESOLUTION_REQUIRED:
                    Log.i(TAG, "Location settings are not satisfied. Show the user a dialog to upgrade location settings ");

                    try {
                        // Show the dialog by calling startResolutionForResult(), and check the result
                        // in onActivityResult().
                        status.startResolutionForResult(MainActivity.this, REQUEST_CHECK_SETTINGS);
                    } catch (IntentSender.SendIntentException e) {
                        Log.i(TAG, "PendingIntent unable to execute request.");
                    }
                    break;
                case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE:
                    Log.i(TAG, "Location settings are inadequate, and cannot be fixed here. Dialog not created.");
                    break;
            }
        }
    });
}

你可以在这里找到完整的例子.

请按照以下步骤操作

1)LocationRequest根据您的意愿创建一个

LocationRequest mLocationRequest = LocationRequest.create()
           .setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY)
           .setInterval(10 * 1000)
           .setFastestInterval(1 * 1000);

2)创建一个LocationSettingsRequest.Builder

LocationSettingsRequest.Builder settingsBuilder = new LocationSettingsRequest.Builder()
               .addLocationRequest(mLocationRequest);
settingsBuilder.setAlwaysShow(true);

3)获取LocationSettingsResponse Task使用以下代码

Task<LocationSettingsResponse> result = LocationServices.getSettingsClient(this)
              .checkLocationSettings(settingsBuilder.build());

注意: LocationServices.SettingsApi不推荐使用,请使用SettingsClient相反.

4)添加a OnCompleteListener以从Task获取结果.Task完成后,客户端可以通过查看LocationSettingsResponse对象的状态代码来检查位置设置.

result.addOnCompleteListener(new OnCompleteListener<LocationSettingsResponse>() {
    @Override
    public void onComplete(@NonNull Task<LocationSettingsResponse> task) {
    try {
        LocationSettingsResponse response = 
                          task.getResult(ApiException.class);
        } catch (ApiException ex) {
            switch (ex.getStatusCode()) {
                case LocationSettingsStatusCodes.RESOLUTION_REQUIRED:
                    try {
                        ResolvableApiException resolvableApiException = 
                                 (ResolvableApiException) ex;
                            resolvableApiException
                                   .startResolutionForResult(MapsActivity.this, 
                                         LOCATION_SETTINGS_REQUEST);
                    } catch (IntentSender.SendIntentException e) {

                    }
                    break;
                case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE:

                    break;
            }
        }
    }
});  

情况1 :: LocationSettingsStatusCodes.RESOLUTION_REQUIRED位置未启用但是,我们可以通过提示用户打开位置(通过调用startResolutionForResult)来要求用户启用该位置.

案例2 :: LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE不满足位置设置.但是,我们无法修复设置,因此我们不会显示对话框.

5) OnActivityResult我们可以在位置设置对话框中获取用户操作.RESULT_OK=>用户打开了位置.RESULT_CANCELLED - 用户拒绝了位置设置请求.

变量声明

private SettingsClient mSettingsClient;
private LocationSettingsRequest mLocationSettingsRequest;
private static final int REQUEST_CHECK_SETTINGS = 214;
