自定义listview适配器行选择

Question

I have listview with custom adapter. In each row i have 2 textviews and a button. I want when I click on an item to highlight it and to stay highlighted until i click another item. I tried to do it with list selector but didn't succeed. Then I tried to do it like this:

public void onClick(View v) {
    ListView lvItems = context.lvLists;
    for (int i=0; i < lvItems.getChildCount(); i++) 
    {
        lvItems.getChildAt(i).setBackgroundColor(Color.BLACK);        
    }
    v.setBackgroundColor(Color.parseColor("#555555"));

This is the onclick of each row of the listview. It works but I saw that when I scroll down there are more items selected (which I didn't select). Solution for this?

Answer 1

If you want to save some properties of your ListView items you can't rely on Views themselves. You have to store them in your data so that your Adapter knows which item's state has changed. See the answer to this question for more details:

Answer 2

您应该实现视图持有人模式，然后在您的持有人代码中，可以有一个（布尔值）变量，该变量保存该项目的当前状态（突出显示或未突出显示），并相应地更改背景颜色。
