Android programming method to implement Listview click expansion and hidden

This article describes the method of Android programming to implement the click expansion and hidden of Listview. Share it for your reference, as follows:

There are many codes, so I find key points and post them. I believe that you will easily understand after reading them.

In listview activity

List&lt;Map&lt;String, Object&gt;&gt; listItems = new ArrayList&lt;Map&lt;String, Object&gt;&gt;()
myAdapter = new MyAdapter(getApplicationContext(), listItems);
(myAdapter);
(new OnItemClickListener() {
 @Override
 public void onItemClick(AdapterView&lt;?&gt; arg0, View arg1, int arg2,
   long arg3) {
   //Set the selected number when clicking, and set the property selectItem in the custom adapter   (arg2);
   //Refresh listView   ();
 }
});

In the custom myAdapter getView, what I need to hide and display is that the TableLayout is hidden by default, and the default values of the int-type selectItem and sign are both -1.

TableLayout info = (TableLayout)(.tableLayout1);
if(position == selectItem){//The selected element  if(sign == selectItem){// When selected again, it will be hidden and the mark position will be initialized     ();
     //The transparent color is not selected   (("#00000000"));
   sign = -1;
  }else{//It will be displayed when selected and marked with this position     ();
     //Selected to set background color   (("#B0E2FF"));
   sign = selectItem;
 }
}else {//Unselected elements  ();
  (("#00000000"));
}

You can click to display, click to hide again, click to display only one element will be displayed.

I hope this article will be helpful to everyone's Android programming design.
