在不导航到设置页面的情况下打开位置服务

120

与提示用户进入设置页面并启用位置服务并再次返回的传统方法相反，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。

参考下面的屏幕截图，它会提示用户一个对话框，只需单击一下即可启用位置服务，并且可以在这些应用中使用。

我怎样才能做到这一点？

此对话框是由Google Play服务中的LocationSettingsRequest.Builder创建的。

您需要向您的应用添加依赖项build.gradle：

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

然后，您可以使用以下最小示例：

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;
            }
        }
    });
}

请遵循以下步骤

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）LocationSettingsResponse Task使用以下代码获取

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

注意： LocationServices.SettingsApi已弃用，请改用SettingsClient代替。

4）添加一个OnCompleteListener以从任务中获取结果。Task完成后，客户端可以通过查看LocationSettingsResponse对象的状态码来检查位置设置。

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，但是我们可以要求用户通过对话框（通过调用startResolutionForResult）打开该位置来启用该位置。

Google Map位置设置请求

情况2：： LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE不满足位置设置。但是，我们无法修复设置，因此不会显示该对话框。

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。

谢谢！如果您在片段中使用此代码，请参见stackoverflow.com/a/39579124/2914140：而不是rae.startResolutionForResult(activity, REQUEST_CHECK_SETTINGS)call startIntentSenderForResult(rae.getResolution().getIntentSender(), REQUEST_CHECK_SETTINGS, null, 0, 0, 0, null)，否则onActivityResult()不会被调用。

@CoolMind谢谢可能用于需要碎片的人

@CoolMind，是否可以使用类似于startIntentSenderForResult该方法的方法openGpsEnableSetting()？
— Aliton Oliveira
@AlitonOliveira，您能详细描述一下吗？在代码中，openGpsEnableSetting()只需启动一个对话框即可启用GPS设置。完成后，用onActivityResult()调用requestCode == REQUEST_ENABLE_GPS。

onActivityResult()是从Activity调用的，我想知道是否有可能将结果返回给Fragmentlike startIntentSenderForResult。

就足够了。这样可以防止您的应用包含不必要的库，并有助于减少方法数量。

Kotlin解决方案

加 build.gradle(Module:app)

implementation 'com.google.android.gms:play-services-location:17.0.0'
implementation 'com.google.android.gms:play-services-maps:17.0.0'

之后创建此功能

fun enablegps() {

    val mLocationRequest = LocationRequest.create()
        .setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY)
        .setInterval(2000)
        .setFastestInterval(1000)

    val settingsBuilder = LocationSettingsRequest.Builder()
        .addLocationRequest(mLocationRequest)
    settingsBuilder.setAlwaysShow(true)

    val result = LocationServices.getSettingsClient(this).checkLocationSettings(settingsBuilder.build())
    result.addOnCompleteListener { task ->

        //getting the status code from exception
        try {
            task.getResult(ApiException::class.java)
        } catch (ex: ApiException) {

            when (ex.statusCode) {

                LocationSettingsStatusCodes.RESOLUTION_REQUIRED -> try {

                    Toast.makeText(this,"GPS IS OFF",Toast.LENGTH_SHORT).show()

                    // Show the dialog by calling startResolutionForResult(), and check the result
                    // in onActivityResult().
                    val resolvableApiException = ex as ResolvableApiException
                    resolvableApiException.startResolutionForResult(this,REQUEST_CHECK_SETTINGS
                    )
                } catch (e: IntentSender.SendIntentException) {
                    Toast.makeText(this,"PendingIntent unable to execute request.",Toast.LENGTH_SHORT).show()

                }

                LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE -> {

                    Toast.makeText(
                        this,
                        "Something is wrong in your GPS",
                        Toast.LENGTH_SHORT
                    ).show()

                }


            }
        }



    }

使用最新的棉花糖更新，即使打开“位置”设置，您的应用也将需要明确请求许可。推荐的方法是显示应用程序的“权限”部分，其中用户可以根据需要切换权限。执行此操作的代码段如下：

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
    
    if (this.checkSelfPermission(Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
    
        final AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setTitle("Location Permission");
        builder.setMessage("The app needs location permissions. Please grant this permission to continue using the features of the app.");
        builder.setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialogInterface, int i) {
                requestPermissions(new String[]{Manifest.permission.ACCESS_COARSE_LOCATION}, PERMISSION_REQUEST_COARSE_LOCATION);
    
            }
        });
        builder.setNegativeButton(android.R.string.no, null);
        builder.show();
    }
} else {
    // do programatically as show in the other answer 
}

并重写以下onRequestPermissionsResult方法：

@Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
        switch (requestCode) {
            case PERMISSION_REQUEST_COARSE_LOCATION: {
                if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                    Log.d(TAG, "coarse location permission granted");
                } else {
                    Intent intent = new Intent();
                    intent.setAction(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
                    Uri uri = Uri.fromParts("package", getPackageName(), null);
                    intent.setData(uri);
                    startActivity(intent);
                }
            }
        }
    }

另一种方法是，您还可以使用SettingsApi来查询启用了哪些位置提供程序。如果未启用任何设置，则可以提示对话框以从应用程序内更改设置。
