Simply code in Andoid Mode

In this code bellow i tried to load different texts(defferent names) from a list after touching the "Details" button on my device..The problem is that it shows me the name only fore some seconds but i want to stay there invariably..

    import ketai.ui.*;
    import android.view.MotionEvent;

    Button on_button;  // the button
    int clk = 1;  

    KetaiGesture gesture;

    KetaiList klist;

    KetaiList selectionlist;
    ArrayList<String> textlist = new ArrayList<String>();

    void setup() {  
      size(1000,600);
      orientation(LANDSCAPE);
      textSize(28);
      textAlign(CENTER);
      gesture = new KetaiGesture(this);
       on_button = new Button("Details", 820, 420, 100, 50);
      textlist.add("Patient 1");
      textlist.add("Patient 2");
      textlist.add("Patient 3");
      textlist.add("Patient 4");
      textlist.add("Patient 15");
    }



    void mousePressed()
    {
      if (on_button.MouseIsOver()) {
        selectionlist = new KetaiList(this,textlist); 
      }
    }  
     void onKetaiListSelection(KetaiList klist)
    {
      String selection = klist.getSelection();
      if (selection == "Patient 1")
      fill(150);
         text("Kathy Smith",30,40);


       if (selection == "Patient 2")
         fill(150);
         text("John Doe",30,40);


       if (selection == "Patient 3")

         fill(150);

         text("Sue White",30,40);

       // if (selection == "Patient 4")



    }
    void draw() {  
     background(255);
        on_button.Draw();



    }
    // ==========================================================
     class Button {
      String label; // button label
      float x;      // top left corner x position
      float y;      // top left corner y position
      float w;      // width of button
      float h;      // height of button

      // constructor
      Button(String labelB, float xpos, float ypos, float widthB, float heightB) {
        label = labelB;
        x = xpos;
        y = ypos;
        w = widthB;
        h = heightB;
      }

      void Draw() {
        fill(150);
        stroke(141);
        rect(x, y, w, h, 10);
        textAlign(CENTER, CENTER);
        fill(0);
        text(label, x + (w / 2), y + (h / 2));
      }

      boolean MouseIsOver() {
        if (mouseX > x && mouseX < (x + w) && mouseY > y && mouseY < (y + h)) {
          return true;
        }
        return false;
      }
      public boolean surfaceTouchEvent(MotionEvent event) {
      // Call to keep mouseX and mouseY constants updated
      //super.surfaceTouchEvent(event);
      // Forward events
      return gesture.surfaceTouchEvent(event);
    }
    }
