As you are using AsyncTask, you can use a ProgressDialog with a message "searching" in onPreExecute method and dismiss it when you are done (in onPostExecute).

In this way, your ListView will also be disabled.

@Override
protected void onPreExecute() {     
    super.onPreExecute();       
    mProgressDialog = ProgressDialog.show(mContext, message, "Please wait...");
    mProgressDialog.setCancelable(false);
}

@Override
protected void onPostExecute(String result) {
    super.onPostExecute(result);
    if(mProgressDialog != null && mProgressDialog.isShowing())
        mProgressDialog.dismiss();

   // set data for listview     
}

While you load, search and get data you can display a header view or/and a footer view in your ListView. Simply add these views before setting the adapter. When you search for a word, call setClickable(false) on the ListView and enable your header/footer view by, for example, calling addFooterView(mFooterView) to show your message.

Notice that you have to add the views before setting the adapter.

Example:

LayoutInflater inflater = getLayoutInflater();
mFooterView = inflater.inflate(R.layout.footer, null, false);
mListView.addFooterView(mFooterView);       
mListView.setAdapter(mAdapter);

After this, feel free to call addFooterView() to show your message and call removeFooterView() to hide your message.

I don't know any direct solution (which there must be), but my way to do this would be:

onPreExecute:

  1. Make your ListView setEnabled(false) so that its not click-able.
  2. Set the visibility of your custom layout (containing searching message) to setVisibility(View.VISIBLE) in order to make it visible on top of your ListView. For that you need to combine your ListView and custom Layout in a FrameLayout.

onPostExecute:

  • Simply reverse the process after you have altered ListView contents

By doing this way, you can show a transparent/translucent area covering your entire ListView with a message on top or center of it.

I've used this approach in one of my project and it looks pretty much nice :)

Why not using the notification to show that the query is executing ?

Because it can ensure the searching continues even you go out to the other apps.

The question you have asked implies the user of your apps waiting a long time to search a word and do nothing else, which is undesirable for the design of Apps for humans
