如何显示Google地图等启用位置对话框？

Question

我使用最新版本的Google Play服务(7.0)并按照其指南中给出的步骤操作,并启用了如下所示的位置对话框,其中包含"从不"按钮.我的应用程序强制要求位置,所以我不想向用户显示永远不会,因为一旦用户点击"从不",我就无法再获取位置或请求位置.

谷歌地图只有是和没有按钮没有从不按钮,任何想法如何实现相同？

LocationSettingsRequest.Builder有一个方法setAlwaysShow(boolean show).虽然该文档表明它目前无效(更新2015-07-05:更新的Google文档已删除此措辞),但设置builder.setAlwaysShow(true);将启用Google地图行为:

这是让它运作的代码:

if (googleApiClient == null) {
    googleApiClient = new GoogleApiClient.Builder(getActivity())
            .addApi(LocationServices.API)
            .addConnectionCallbacks(this)
            .addOnConnectionFailedListener(this).build();
    googleApiClient.connect();

    LocationRequest locationRequest = LocationRequest.create();
    locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
    locationRequest.setInterval(30 * 1000);
    locationRequest.setFastestInterval(5 * 1000);
    LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder()
            .addLocationRequest(locationRequest);

    //**************************
    builder.setAlwaysShow(true); //this is the key ingredient
    //**************************

    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();
            final LocationSettingsStates state = result.getLocationSettingsStates();
            switch (status.getStatusCode()) {
                case LocationSettingsStatusCodes.SUCCESS:
                    // All location settings are satisfied. The client can initialize location
                    // requests here.
                    break;
                case LocationSettingsStatusCodes.RESOLUTION_REQUIRED:
                    // Location settings are not satisfied. But could be fixed by showing the user
                    // a dialog.
                    try {
                        // Show the dialog by calling startResolutionForResult(),
                        // and check the result in onActivityResult().
                        status.startResolutionForResult(
                                getActivity(), 1000);
                    } catch (IntentSender.SendIntentException e) {
                        // Ignore the error.
                    }
                    break;
                case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE:
                    // Location settings are not satisfied. However, we have no way to fix the
                    // settings so we won't show the dialog.
                    break;
            }
        }
    });
}

对于那些正在寻找处理是/否按钮的人,我想对kai的答案添加一些更改.

在您的活动中声明此常量

protected static final int REQUEST_CHECK_SETTINGS = 0x1;

打电话给settingsrequest()你的onStart()

public void settingsrequest()
    {
        LocationRequest locationRequest = LocationRequest.create();
        locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
        locationRequest.setInterval(30 * 1000);
        locationRequest.setFastestInterval(5 * 1000);
        LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder()
                .addLocationRequest(locationRequest);
        builder.setAlwaysShow(true); //this is the key ingredient

        PendingResult<LocationSettingsResult> result =
                LocationServices.SettingsApi.checkLocationSettings(mGoogleApiClient, builder.build());
        result.setResultCallback(new ResultCallback<LocationSettingsResult>() {

Answer 3

LocationServices.SettingsApi现在已弃用,因此我们使用SettingsClient

    LocationRequest mLocationRequest = new LocationRequest();
        mLocationRequest.setInterval(10);
        mLocationRequest.setSmallestDisplacement(10);
        mLocationRequest.setFastestInterval(10);
        mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
        LocationSettingsRequest.Builder builder = new 
        LocationSettingsRequest.Builder();
        builder.addLocationRequest(mLocationRequest);

然后检查是否满足当前位置设置.创建LocationSettingsResponse任务:

        Task<LocationSettingsResponse> task=LocationServices.getSettingsClient(this).checkLocationSettings(builder.build());

然后添加Listener

task.addOnCompleteListener(new OnCompleteListener<LocationSettingsResponse>() {
            @Override
                    public void onComplete(Task<LocationSettingsResponse> task) {
                        try {
                            LocationSettingsResponse response = task.getResult(ApiException.class);
                            // All location settings are satisfied. The client can initialize location
                            // requests here.

                        } catch (ApiException exception) {
                            switch (exception.getStatusCode()) {
                                case LocationSettingsStatusCodes.RESOLUTION_REQUIRED:
                                    // Location settings are not satisfied. But could be fixed by showing the
                                    // user a dialog.
                                    try {
                                        // Cast to a resolvable exception.
                                        ResolvableApiException resolvable = (ResolvableApiException) exception;
                                        // Show the dialog by calling startResolutionForResult(),
                                        // and check the result in onActivityResult().
                                        resolvable.startResolutionForResult(
                                                HomeActivity.this,
                                                101);
                                    } catch (IntentSender.SendIntentException e) {
                                        // Ignore the error.
                                    } catch (ClassCastException e) {
                                        // Ignore, should be an impossible error.
                                    }
                                    break;
                                case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE:
                                    // Location settings are not satisfied. However, we have no way to fix the
                                    // settings so we won't show the dialog.
                                    break;
                            }
                        }
                    }
                });

添加了onActivityResult

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        final LocationSettingsStates states = LocationSettingsStates.fromIntent(data);
        switch (requestCode) {
            case 101:
                switch (resultCode) {
                    case Activity.RESULT_OK:
                        // All required changes were successfully made
                        Toast.makeText(HomeActivity.this,states.isLocationPresent()+"",Toast.LENGTH_SHORT).show();
                        break;
                    case Activity.RESULT_CANCELED:
                        // The user was asked to change settings, but chose not to
                        Toast.makeText(HomeActivity.this,"Canceled",Toast.LENGTH_SHORT).show();
                        break;
                    default:
                        break;
                }
                break;
        }
    }

Ola Cabs正在使用新发布的Settings API来实现此功能.根据新API,用户无需导航到设置页面即可启用位置服务,从而实现无缝集成.请阅读以下内容了解更多详情:

GoogleApiClient 已弃用。Kotlin 中的新实现如下。

依赖关系

// Google Maps Location Services
implementation 'com.google.android.gms:play-services-location:17.1.0'
implementation 'com.google.android.gms:play-services-maps:17.0.0'

代码

val locationRequest = LocationRequest.create()
    .setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY)
    .setInterval(30 * 1000)
    .setFastestInterval(5 * 1000)

val builder = LocationSettingsRequest.Builder()
    .addLocationRequest(locationRequest)
    .setAlwaysShow(true)

val pendingResult = LocationServices
    .getSettingsClient(activity)
    .checkLocationSettings(builder.build())

pendingResult.addOnCompleteListener { task ->
    if (task.isSuccessful.not()) {
        task.exception?.let {
            if (it is ApiException && it.statusCode == LocationSettingsStatusCodes.RESOLUTION_REQUIRED) {
                // Show the dialog by calling startResolutionForResult(),
                // and check the result in onActivityResult().
                (it as ResolvableApiException).startResolutionForResult(activity,
                    MainActivity.REQUEST_CODE_LOCATION)
            }
        }
    }
}
