How to show loading message in recyclerview


How to show loading message in recyclerview

To fix the issue you can do Add ProgressBar to your class and layout (near your recicleView). If you want text: add LinearLayout and place there ProgressBar and TextView (trigger visibility on linearLayout):
code :
ProgressBar bar;
bar.setVisibility(VISIBLE);
recicleView.setVisibility(GONE);     
service.getComenzileMele(user).enqueue(listener);
Callback<List<CustomObject>> listener = new Callback<List<CustomObject>>() {

    @Override
    public void onResponse(Call<List<CustomObject>> call, Response<List<CustomObject>> response) {
        bar.setVisibility(GONE);
        recicleView.setVisibility(VISIBLE);
    }

    @Override
    public void onFailure(Call<List<CustomObject>> call, Throwable t) {
        bar.setVisibility(GONE);
        recicleView.setVisibility(VISIBLE);         
    }
};

show loading message while loading contents in asp using jquery ajax

show loading message while loading contents in asp using jquery ajax

I think the issue was by ths following , Simple form of AJAX is the .get() method which should be enough for your needs.
First of all, add a placeholder in your HTML where the loading image will appear then when you have the contents loaded, those contents will be placed instead of the image.
code :
<div id="ContentsPlaceholder"></div>
$(function() {
    $("#ContentsPlaceholder").html("<img src='Loading.gif' />");
    $.get("GetData.asp", function(contents) {
        $("#ContentsPlaceholder").html(contents);
    });
});

like below fixes the issue Instead of using the FileContentResult directly to the end browser, I would return a standard View telling the user that the file is being generated. Then fire an AJAX POST to the server which triggers the file generation, and saves the result to the server. Once the server has generated the file, notify the user that it is available to download, or have the browser navigate to the file download.
How do i show the progress bar while recyclerview is loading and hide it when done?

To fix this issue Call stopProgressbar() from onResponse() and onErrorResponse() method.
Here is an example:
code :
public void loadData()
{
    JsonObjectRequest jsonObjReq = new JsonObjectRequest(Method.GET,
            url, null,
            new Response.Listener<JSONObject>() {

                @Override
                public void onResponse(JSONObject response) {
                    Log.d(TAG, response.toString());

                    // Parse JSON data and add to list
                    ...........
                    ...........................

                    // Hide progressbar
                    stopProgressbar();
                }
            }, new Response.ErrorListener() {

                @Override
                public void onErrorResponse(VolleyError error) {
                    VolleyLog.d(TAG, "Error: " + error.getMessage());

                    // Hide progressbar
                    stopProgressbar();                    
                }
            });

fixed the issue. Will look into that further With the help of the answer of written by azizbekian, I found the answer to my question.
As mentioned in that answer, this is the procedure;
code :
 int loadedPercentage = 0;
 boolean loaded = false;
 mathView.setWebChromeClient(new WebChromeClient(){
     public void onProgressChanged(WebView view, int newProgress) {
         super.onProgressChanged(view, newProgress);
         loadedPercentage = newProgress;
         if(newProgress==100) {
             //When the loading is 100% completed; todo
             loaded = true;
             Toast.makeText(getContext(), newProgress + "LOADED COMPLETELY", Toast.LENGTH_SHORT).show();
         }
     }
 });
public class MyMathView extends WebView {
    private String TAG = "KhanAcademyKatexView";
    private static final float default_text_size = 18;
    private String display_text;
    private int text_color;
    private int text_size;
    private boolean clickable = false;

    private boolean loaded = false;

Show Toast Message if RecyclerView is empty

wish of those help You can check isEmpty() for Array List you are using.
isEmpty() Returns true if list contains no elements.
code :
current.add(entry);
if(current.isEmpty()){
  Toast.makeText(YourActivity.this,"No data", Toast.LENGTH_LONG).show();
}else{
  adapter = new CurrentAdapter(current, getActivity().getApplicationContext());
  recyclerView.setAdapter(adapter);
}
