Question

我尝试使用google places api使用PlaceDetectionApi检测设备的当前位置。我希望如果未启用所需的设置来检测当前位置，则启动解决方案应提示用户启用位置服务，而无需构建LocationSettings对象并明确调用它以进行解析。我错过了什么吗？

您可以手动检查位置模式是否已禁用，如果禁用，您可以直接打开设置以启用它，如图所示：

 public static boolean isLocationServicesAvailable(Context context) {
        int locationMode = 0;
        String locationProviders;
        boolean isAvailable = false;

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
            try {
                locationMode = Settings.Secure.getInt(context.getContentResolver(), Settings.Secure.LOCATION_MODE);
            } catch (Settings.SettingNotFoundException e) {
                e.printStackTrace();
            }

            isAvailable = (locationMode != Settings.Secure.LOCATION_MODE_OFF);
        } else {
            locationProviders = Settings.Secure.getString(context.getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED);
            isAvailable = !TextUtils.isEmpty(locationProviders);
        }

        // boolean coarsePermissionCheck = (ContextCompat.checkSelfPermission(context, Manifest.permission.ACCESS_COARSE_LOCATION) == PackageManager.PERMISSION_GRANTED);
        // boolean finePermissionCheck = (ContextCompat.checkSelfPermission(context, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED);

        return isAvailable;
    }

在禁用的情况下

打开设置：

if(!isLocationServicesAvailable(this)) {
            // notify user
            AlertDialog.Builder dialog = new AlertDialog.Builder(this);
            dialog.setMessage("enabled");
            dialog.setPositiveButton("open GPS", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface paramDialogInterface, int paramInt) {
                    // TODO Auto-generated method stub
                    Intent myIntent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
                    startActivity(myIntent);
                    //get gps
                }
            });
            dialog.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {

                @Override
                public void onClick(DialogInterface paramDialogInterface, int paramInt) {
                    // TODO Auto-generated method stub

                }
            });
            dialog.show();
        }

Google的LocationSettings将api置于检测当前位置
