here, how to print ss value from Activity's oncreate() method?

    MainActivity extends Activity {

      public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        this.setContentView(R.layout.activity_main);
        view1 = (TextView)findViewById(R.id.ss_View);

        //view.setText(String.valueOf(ss)); 
      }

      private class x {
        @Override
        public void func() {
         int ss = 3;
        }
      }
    }

Answer 1

Make ss an instance variable of the x class and add a getter method:

public class InnerActivity extends Activity {

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        this.setContentView(R.layout.activity_main);
        TextView view = (TextView) findViewById(R.id.clickableButtonWithBorder);

        x xInstance = new x();
        xInstance.func();
        view.setText(String.valueOf(xInstance.getSS()));

    }

    private class x {
        int ss;

        public void func() {
            ss = 3;
        }

        public Integer getSS()
        {
            return ss;
        }
    }

}

Answer 2

You can't do this. SS variable is only created locally in your method. Create ss variable as field of class and generate getter. Then you can get your variable.
