Question

How to show the alert dialog for the empty list view when there are no listview items. Please find the below image having three text fields. I have to implement the empty list view when there are no records/unmatched records in the list.

The list view is implemented as below:

ListView empListView; 
empListView = (ListView)findViewById(R.id.list1 );

I have to show the alert dialog box for the empListView. Please help me with the samplecode/links.

It all depends on how you implement the setAdapter method etc. But here is an example:

if(cdata.getCount()==0) {
  //empty, show alertDialog
  AlertDialog.Builder builder = new AlertDialog.Builder(this);
  builder.setMessage("Search is empty")
   .setCancelable(true)
   .setPositiveButton("Ok", new DialogInterface.OnClickListener() {
       public void onClick(DialogInterface dialog, int id) {
            dialog.cancel();
       }
   });
  AlertDialog alert = builder.create();
} 
else {
  //Not empty, set the adapter or do what you want. 
  empListview.setAdapter(new MyCursorAdapter( getApplicationContext(), R.layout.listview, cdata, fields, names));
}

The code above havent been tested. But should work with minor adjustments, I might have forgotten something.
