Android 安卓GPS按钮点击时启用

这是我的密码。（它使alertdialog移动设置） 但我只想在点击“启用GPS”按钮时启用GPS。 当我运行应用程序而不是只运行一次时，android是否总是启用按钮点击

AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setMessage("Your GPS is disabled! Would you like to enable it?")
.setCancelable(false)
.setPositiveButton("Enable GPS",
new DialogInterface.OnClickListener() {
    public void onClick(DialogInterface dialog, int id) {
        moveConfigGPS();
    }
}).setNegativeButton("Do nothing",
new DialogInterface.OnClickListener() {
    public void onClick(DialogInterface dialog, int id) {
        dialog.cancel();
    }
});

AlertDialog alert = builder.create();
alert.show();

您不能仅启用GPS，您只能出于以下目的打开GPS设置：

Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
startActivity(intent);

更新：

  /**
 * Check if GPS enabled or not
 * and request dialog to enable GPS.
 */
private void checkWhetherLocationSettingsAreSatisfied() {

    LocationRequest mLocationRequest = LocationRequest.create()
            .setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY)
            .setInterval(1000)
            .setNumUpdates(2);

    final LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder().addLocationRequest(mLocationRequest);
    builder.setAlwaysShow(true);
    builder.setNeedBle(true);
    SettingsClient client = LocationServices.getSettingsClient(this);
    Task<LocationSettingsResponse> task = client.checkLocationSettings(builder.build());
    task.addOnSuccessListener(this, new OnSuccessListener<LocationSettingsResponse>() {
        @Override
        public void onSuccess(LocationSettingsResponse locationSettingsResponse) {
            Log.d(TAG, "onSuccess() called with: locationSettingsResponse = [" + locationSettingsResponse + "]");
            hasLocationPermission();

        }
    });
    task.addOnFailureListener(this, new OnFailureListener() {
        @Override
        public void onFailure(@NonNull Exception e) {
            Log.d(TAG, "onSuccess --> onFailure() called with: e = [" + e + "]");
            if (e instanceof ResolvableApiException) {
                // Location settings are not satisfied, but this can be fixed
                // by showing the user a dialog.
                try {
                    // Show the dialog by calling startResolutionForResult(),
                    // and check the result in onActivityResult().
                    ResolvableApiException resolvable = (ResolvableApiException) e;
                    resolvable.startResolutionForResult(BaseActivity.this,
                            Constants.REQUEST_CHECK_SETTINGS);
                } catch (IntentSender.SendIntentException e) {

                    e.printStackTrace();
                }

        }

            hasLocationPermission();

        } else {
            //User clicks No
        }

我想你想像谷歌一样，只需点击一下就可以打开GPS定位

要提示用户修改位置设置的权限，请调用startResolutionForResult（Activity，int）。此方法将打开一个对话框，请求用户允许修改位置设置

嘿，有没有一种方法可以检测用户何时从上面的对话框中单击“否”按钮？？？是的。您将在活动中获得resultCode多次尝试，但无论如何都无法获得。感谢您的回复。谢谢，为我工作
