如何顯示像谷歌地圖這樣的啟用位置對話框？

Question

我使用最新版本的 Google Play 服務 (7.0) 並按照他們的指南中給出的步驟進行操作，我啟用了如下所示的位置對話框，其中有一個“從不”按鈕。 我的應用程序強制需要位置，所以我不想向用戶顯示“從不”，因為一旦用戶點擊“從不”，我就根本無法獲取位置或再次請求位置。

谷歌地圖只有 yes 和 no 按鈕而沒有 never 按鈕，知道如何實現嗎？

LocationSettingsRequest.Builder有一個方法setAlwaysShow(boolean show) 。 雖然該文檔表明它目前什么都不做（更新 2015-07-05：更新的 Google 文檔已刪除此措辭），但設置builder.setAlwaysShow(true); 將啟用谷歌地圖行為：

這是讓它工作的代碼：

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;
            }
        }
    });
}

對於那些正在尋找處理是/否按鈕的人，我想對 kai 的答案進行一些更改。

在您的活動中聲明此常量

protected static final int REQUEST_CHECK_SETTINGS = 0x1;

在 onStart() 中調用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) {

Answer 3

LocationServices.SettingsApi 現在已棄用，因此我們使用 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);

然后檢查是否滿足當前位置設置。 創建 LocationSettingsResponse 任務：

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

然后添加監聽器

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.
                                    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;
        }
    }

Answer 7

您還可以為 Builder 添加多個 LocationRequests 以實現“使用 GPS、Wi-Fi 和移動網絡進行定位”對話框，而不僅僅是“使用 GPS 定位”

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());

在 Kotlin 中，使用以下代碼：

import android.app.Activity
import android.content.Intent
import android.content.IntentSender
import android.os.Bundle
import android.util.Log
import androidx.appcompat.app.AppCompatActivity
import com.google.android.gms.common.api.GoogleApiClient
import com.google.android.gms.common.api.PendingResult
import com.google.android.gms.common.api.Status
import com.google.android.gms.location.*

class MainActivity : AppCompatActivity() {
    private var googleApiClient: GoogleApiClient? = null
    private val REQUESTLOCATION = 199
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        enableLoc()
    }
    private fun enableLoc() {
        googleApiClient = GoogleApiClient.Builder(this)
            .addApi(LocationServices.API)
            .addConnectionCallbacks(object : GoogleApiClient.ConnectionCallbacks {
                override fun onConnected(bundle: Bundle?) {}
                override fun onConnectionSuspended(i: Int) {
                    googleApiClient?.connect()
                }
            })
            .addOnConnectionFailedListener {
            }.build()
        googleApiClient?.connect()
        val locationRequest = LocationRequest.create()
        locationRequest.priority = LocationRequest.PRIORITY_HIGH_ACCURACY
        locationRequest.interval = 30 * 1000.toLong()
        locationRequest.fastestInterval = 5 * 1000.toLong()
        val builder = LocationSettingsRequest.Builder()
            .addLocationRequest(locationRequest)
        builder.setAlwaysShow(true)
        val result: PendingResult<LocationSettingsResult> =
            LocationServices.SettingsApi.checkLocationSettings(googleApiClient, builder.build())
        result.setResultCallback { result ->
            val status: Status = result.status
            when (status.statusCode) {
                LocationSettingsStatusCodes.RESOLUTION_REQUIRED -> try {
                    status.startResolutionForResult(
                        this@MainActivity,
                        REQUESTLOCATION
                    )
                } catch (e: IntentSender.SendIntentException) {
                }
            }
        }
    }
    override fun onActivityResult(
        requestCode: Int,
        resultCode: Int,
        data: Intent?
    ) {
        super.onActivityResult(requestCode, resultCode, data)
        when (requestCode) {
            REQUESTLOCATION -> when (resultCode) {
                Activity.RESULT_OK -> Log.d("abc","OK")
                Activity.RESULT_CANCELED -> Log.d("abc","CANCEL")

這是我的 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) {
                }
            }
        }
    }
}

並使用下面的 get Result 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.")
  }
}

Answer 11

GoogleApiClient 已棄用。 Kotlin 中的新實現如下。

依賴關系

// 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'

代碼

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)
            }
        }
    }
}
