java.lang.RuntimeException: Unable to start activity ComponentInfo{com.symplycode.newloginregister/com.symplycode.newloginregister.UserAreaActivity}: java.lang.ClassCastException: android.support.v7.widget.AppCompatTextView cannot be cast to android.widget.EditText

Answer 1

 final EditText etUsername=(EditText) findViewById(R.id.etUsername);
        final EditText etAge=(EditText) findViewById(R.id.etAge);

must be

 final TextView etUsername=(TextView) findViewById(R.id.etName);
        final TextView etAge=(TextView) findViewById(R.id.etAge);

You are trying to cast an TextView widget to a EditText widget. Either change it like my example or change the TextView inside your xml layout to EditText

By the way, there is no view with the id etUsernameinside your layout, maybe it´s a typo and you mean etName ? Be sure you are using the correct layout xml...

The layout that you set with setContentView(R.layout.activity_user_area); must be the layout where both views are inside...
