如何显示 Google 地图之类的启用位置对话框？

Question

我使用最新版本的 Google Play Services (7.0) 并按照他们的指南中给出的步骤进行操作，我启用了如下所示的位置对话框，其中有一个 "never" 按钮。我的应用程序强制需要位置，所以我不想向用户显示 "never"，因为一旦用户点击 "never"，我就根本无法获取位置或再次请求位置。

因为 Google 地图只有是和没有按钮而没有从不按钮，知道如何实现相同的吗？

LocationSettingsRequest.Builder 有一个方法 setAlwaysShow(boolean show)。 ~~虽然文档表明它当前什么都不做~~（更新于 2015-07-05：更新的 Google 文档已删除此措辞），设置 builder.setAlwaysShow(true); 将启用 Google 地图行为：

这是让它工作的代码：

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;
            }
        }
    });
}

我想为那些正在寻找处理 Yes/No 按钮的人添加对 kai 的回答的一些更改。

在您的 activity

中声明此常量

protected static final int REQUEST_CHECK_SETTINGS = 0x1;

在您的 onStart()

中调用 settingsrequest()

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>() {
            @Override
            public void onResult(LocationSettingsResult result) {
                final Status status = result.getStatus();

Answer 6

您还可以为 Builder 添加多个 LocationRequests 以实现 "Use GPS, Wi-Fi and mobile networks for location" 对话框而不是 "Use GPS for location"

LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder()
                .addLocationRequest(createLocationRequest(LocationRequest.PRIORITY_BALANCED_POWER_ACCURACY))
                .addLocationRequest(createLocationRequest(LocationRequest.PRIORITY_HIGH_ACCURACY))
                .setAlwaysShow(true);

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

Answer 7

LocationServices.SettingsApi 现在已弃用，所以我们使用 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());

然后添加监听器

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.

已添加 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;

GoogleApiClient 已弃用。 Kotlin 中的新实现可以如下所示。

依赖项

// 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)

这是我的 Kotlin 示例-

  private fun enableLocation() {
    val locationRequest = LocationRequest.create()
    locationRequest.apply {
        priority =LocationRequest.PRIORITY_HIGH_ACCURACY
        interval = 30 * 1000.toLong()
        fastestInterval = 5 * 1000.toLong()
    }
    val builder = LocationSettingsRequest.Builder()
            .addLocationRequest(locationRequest)
    builder.setAlwaysShow(true)
    val result=
            LocationServices.getSettingsClient(requireContext()).checkLocationSettings(builder.build())
    result.addOnCompleteListener {
        try {
            val response: LocationSettingsResponse = it.getResult(ApiException::class.java)
            println("location>>>>>>> ${response.locationSettingsStates.isGpsPresent}")
            if(response.locationSettingsStates.isGpsPresent)
                //do something
        }catch (e: ApiException){
            when (e.statusCode) {
                LocationSettingsStatusCodes.RESOLUTION_REQUIRED -> try {
                    val intentSenderRequest =
                        IntentSenderRequest.Builder(e.status.resolution).build()
                    launcher.launch(intentSenderRequest)
                } catch (e: IntentSender.SendIntentException) {
                }
            }
        }
    }
}

并使用下面的获取结果方法

 private var launcher=  registerForActivityResult(ActivityResultContracts.StartIntentSenderForResult()){ result->
  if (result.resultCode == Activity.RESULT_OK) {
      Log.d(TAG, "OK")
      
  } else {
      Log.d(TAG, "CANCEL")
      requireContext().toast("Please Accept Location enable for use this App.")
  }
}
