Answer 1

May be you should check that the edit text is not empty before calling getText().toString()..

 if(uname_ET.getText() != null) String nameToInsert = (String) uname_ET.getText().toString();
 if(dname_ET.getText() != null) String drugnameToInsert = (String) dname_ET.getText().toString();

Answer 2

i think problem is this u have set button ,edittext etc ...object this way

 Button Savebutton=(Button)findViewById(R.id.savebutton);  

for custome dialog u have to set object as shown below

 Button Savebutton=(Button)dialog.findViewById(R.id.savebutton);    

where dialog is a object as

  Dialog dialog = new Dialog(YourActivity.this);
