GPS 定位已启用，但无法找到设备位置

Question

应用程序卡在白色对话框中，即使在启用位置后也是如此。 如下所述，有两个文件用于定位责任。

1. RemindActivity.java：

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.remind_activity);
  locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
.
.
.
        LocationPremissionCheck();
        GooglePlayServiceCheck();
        GPSLocationServiceCheck();
.
.
.
}

 private void GPSLocationServiceCheck() {
        if (!locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER)) {

            final AlertDialog.Builder builder = new AlertDialog.Builder(this);
            builder.setMessage("Your GPS seems to be disabled, enable it to use this app?")
                    .setCancelable(false)
                    .setPositiveButton("Yes", new DialogInterface.OnClickListener() {
                        public void onClick(@SuppressWarnings("unused") final DialogInterface dialog, @SuppressWarnings("unused") final int id) {
                            startActivity(new Intent(android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS));
                        }
                    })
                    .setNegativeButton("No", new DialogInterface.OnClickListener() {
                        public void onClick(final DialogInterface dialog, @SuppressWarnings("unused") final int id) {
                            dialog.cancel();
                            Intent intent = new Intent(RemindActivity.this, StartActivity.class);
                            intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
                            startActivity(intent);
                            finish();

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

上面同样的东西写在RemindActivity.java中如下：

1. RemindActivity.java：

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.remind_activity);
  locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
.
.
.
        LocationPremissionCheck();
        GooglePlayServiceCheck();
        GPSLocationServiceCheck();
.
.
.
}

 private void GPSLocationServiceCheck() {
        if (!locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER)) {

            final AlertDialog.Builder builder = new AlertDialog.Builder(this);
            builder.setMessage("Your GPS seems to be disabled, enable it to use this app?")
                    .setCancelable(false)
                    .setPositiveButton("Yes", new DialogInterface.OnClickListener() {
                        public void onClick(@SuppressWarnings("unused") final DialogInterface dialog, @SuppressWarnings("unused") final int id) {
                            startActivity(new Intent(android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS));
                        }
                    })
                    .setNegativeButton("No", new DialogInterface.OnClickListener() {
                        public void onClick(final DialogInterface dialog, @SuppressWarnings("unused") final int id) {
                            dialog.cancel();
                            Intent intent = new Intent(RemindActivity.this, StartActivity.class);
                            intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
                            startActivity(intent);
                            finish();

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

这是一个注册屏幕，此位置适用于某些设备，但不适用于所有设备（正如我测试的那样）。 应用程序卡在白色对话框中，即使在启用位置后也是如此。

如何解决此问题。 提前致谢。

如果您只是想检查应用程序在前台时是否启用了位置，请使用以下方法。

一旦您启动位置源设置，关闭对话框并在您的活动中显示一些刷新按钮。当您点击刷新按钮时，再次重新创建活动。

     public void onClick(@SuppressWarnings("unused") final DialogInterface dialog, @SuppressWarnings("unused") final int id) {
                            startActivity(new Intent(android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS));
                             finish();
                        }

     //in your activity
        public void onRefresh() {
             reCreate();
            }
    }
