@ Dhina : I think you are nor read my question. Please read first and then write the comment.I know what is Shared Preferences and how to use. I want to know how to get button click event in boolean values in true or false whenever go to that page.This is my issue. — p. ld, Dec 18 '15 at 07:26
@p. ld : Please clarify what you exactly want to do ? When you click on button this already set preference "strUserName" as true. Then what is the problem please clarify so that can help you in better way. — Hitesh Bhalala, Dec 18 '15 at 07:32
See , whenever i go to that particular Activity , i want to save value in true if i pressed button and if not then save false. So how i want to know i click the button or not . — p. ld, Dec 18 '15 at 07:39
use shared preference in common class as static field, so easy you can edit as well as get data from it. — prakash, Dec 18 '15 at 07:47

As simple you can do like this,

Filter_Screen:

imgBtn_LogOut.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) 
{
SharedPreferences sharedPreferences = PreferenceManager.getDefaultSharedPreferences(getApplicationContext());
SharedPreferences.Editor editor = sharedPreferences.edit();
editor.putBoolean("strUserName", true);
editor.commit();
Intent i = new Intent(Filter_Screen.this, Login_Screen.class);
startActivity(i);
finish();
}
});

Login_Screen:

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.layout_activity);
SharedPreferences sharedPreferences = PreferenceManager.getDefaultSharedPreferences(getApplicationContext());
sharedPreferences.getBoolean("strUserName",false);
}

:But when i comeback on Filter_Screen then call onResume (). — p. ld, Dec 18 '15 at 07:43
@p.ld you can use sharedPreferences.getBoolean("strUserName",false); method on create — hugerde, Dec 18 '15 at 07:45

you can create,,

Toast.makeText(this,"button select!",Toast.LENGTH_LONG).show();

for all the buttons, it could notify you which button you have selected. OR try using a print in, if and else statements,, may be it work.
