add buttons at the end of selected listview item in android dynamically?

Question

I have a listview in which my list contain textview,means I have a list of text where user can select the text, read it and set margin note at the end of that text and a button is created over there. So when next time the user read that text then the button/buttons is there and when click on that button a popup is open where he can see his margin note. Now the problem is that he can create more than one margin note at the end. In this case I have to create one or more button dynamically at the end of that selected textview. So please help me I am unable to create more than one button dynamically.

Answer 1

There are a couple of ways to do it.

1) Create the buttons (max the user will require) already in the xml file of the list item element and set their visibility to invisible or gone. When the user selects it you can set the visibility to visible. The visibility can be set dynamically.

2) The other way is to add buttons programatically. List views do reuse views for performance purposes. this could explain as to why you are having trouble with the button moving positions. in this case you have identify the id of the list item and add and remove buttons every time the view is created in your getView method of your list adapter.

• Remember to chk the condition on your getView method and set visibility or add/remove button.

      lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        public void onItemClick(AdapterView<?> list, View v, int pos, long id) {
            System.out.println("I clicked row item");
            button1= (Button)v.findViewById(R.id.button1);
            button1.setVisibility(button1.isShown() ? View.GONE : View.VISIBLE);}
