How to filter from list view items containing image and text in custom adapter by entering text in edittext view

Question

My motive is to filter and show items entered by user in edit textview from the list view items containing image and textview.But I am not able to filter properly (implementation is not correct i guess + newbie to Android)

I want to filter it by textview which is attached in adapter.I am able to list items properly in list view (image + text). Only thing I want is in the edit text, if I enter any words, it should filter the list view items. I have searched for the same and tried,but not successful. For now I am referring this tutorial: http://www.androidbegin.com/tutorial/android-search-filter-listview-images-and-texts-tutorial/

Any help would be appreciated. Thanks

1. Displaylist.java

   YouTubeAdapter you;
   ArrayList<String> VideoURL=new ArrayList<String>();
   ArrayList<String> VideoID=new ArrayList<String>();
   ArrayList<String> VideoTitle=new ArrayList<String>();
   ArrayList<String> VideoThumb=new ArrayList<String>();
   protected void onCreate(Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);
   setContentView(R.layout.activity_display_list_view);
   lv=(ListView)findViewById(R.id.lv);
   you=new YouTubeAdapter(DisplayListView.this,VideoURL,VideoTitle);
   lv.setAdapter(you);
   et_search = (EditText) findViewById(R.id.et_search);
   
   et_search.addTextChangedListener(new TextWatcher() {
       @Override
       public void beforeTextChanged(CharSequence s, int start, int count, int after) {
   
       }
   
       @Override
       public void onTextChanged(CharSequence s, int start, int before, int count) {
   
       }
   
       @Override
       public void afterTextChanged(Editable s) {
           String text = et_search.getText().toString().toLowerCase(Locale.getDefault());
           you.filter(text);
       }
   });
   }
   

2. Adapter.java

   ArrayList<String> mVideo=new ArrayList<String>();
   ArrayList<String> mTitle=new ArrayList<String>();
   ArrayList<String> mThumb=new ArrayList<String>();
   List<String> orig;
   // Filter Class
   public void filter(String charText) {
    charText = charText.toLowerCase(Locale.getDefault());
    orig.clear();
   Log.i(TAGYTAdap,"charText:"+charText);
   if (charText.length() == 0) {
       orig.addAll(mTitle);
   } else {
       for (String wp : mTitle) {
           Log.i(TAGYTAdap,"wp:"+wp);
          if (wp.toLowerCase(Locale.getDefault())
                   .contains(charText)) {
               orig.add(wp);
           }
        }
     }
       notifyDataSetChanged();
   }

Search View and Edittext both can be use for this filter thing but Search view is better one.!

here you go now this will work fine.! hope so

I have done same thing here is my code.!

 // Filter Function
    public void filter(String charText) {
        charText = charText.toLowerCase(Locale.getDefault());
        worldpopulationlist.clear();
        if (charText.length() == 0) {
            worldpopulationlist.addAll(arraylist);
        }
        else
        {
            for (Words wp : arraylist)
            {
                if (wp.getName().toLowerCase(Locale.getDefault()).contains(charText))
                {
                    worldpopulationlist.add(wp);
                }
            }
        }
        notifyDataSetChanged();
    }

}

And called it in Main.!

 // Capture Text in EditText
        editsearch.addTextChangedListener(new TextWatcher() {

            @Override
            public void afterTextChanged(Editable arg0) {
                // TODO Auto-generated method stub
                String text = editsearch.getText().toString().toLowerCase(Locale.getDefault());
                adapter.filter(text);
            }

            @Override
            public void beforeTextChanged(CharSequence arg0, int arg1,
                                          int arg2, int arg3) {
                // TODO Auto-generated method stub
            }

            @Override
            public void onTextChanged(CharSequence arg0, int arg1, int arg2,
                                      int arg3) {
                // TODO Auto-generated method stub
            }
        });
