ListView events

First, click on the event setOnItemClickListener

Activity interfaces need to achieve AdapterView.OnItemClickListener

And calls lv.setOnItemClickListener (this) in OnCreate method

    //i代表position
    @Override
    public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
        Toast.makeText(this, "点击"+i, Toast.LENGTH_SHORT).show();
    }

Second, long press event setOnItemLongClickListener

Activity interfaces need to achieve AdapterView.OnItemLongClickListener

And calls lv.setOnItemLongClickListener (this) in OnCreate method

    // Why here we need to return value it? true representatives digest event, we will not continue to pass.
    // false off event on behalf of indigestion, will continue to pass. Long press to be triggered, after the click event triggers 
    @Override
     public  boolean onItemLongClick (AdapterView <?> AdapterView, View View, int i, Long L) { 
        Toast.makeText ( the this , "long press" + i, Toast.LENGTH_SHORT) the .Show ();
         return  to true ; 
    }
