Trying to clear the edittext1  with appIdStrVal.setText(""); but it is not working . initally it will take the old value if one click the button twice it is working.

dj_alikCommented:
Let's make some clean for code:
can you work with public reference of  EditTextStrVal  not in click event.
Save the reference Oncreate for performance issue.

Did you mean that  text is changed (empty) only on second click all time or in first time?

roy_sanuAuthor Commented:
it works on the second click only not on the first click

dj_alikCommented:
Why you need this lines:
 appIdStrVal.setText("");

it always will be empty
appIdStr = appIdStrVal.getEditableText().toString
