Child Click Listener 上的 android Expandable ListView 不起作用

Question

我有一个ExpandableListView 列表运行良好，但我想当我点击 Childs 时，时钟图标改变颜色并做某事并保存，但是当我点击孩子时，第一个时钟第一个孩子做这项工作，但是当我向下滚动一个随机孩子或其中 2 o 3 个也会改变颜色时，如果我关闭应用程序这个操作系统我的适配器代码，它将被保存

这是我的片段代码，时钟类是时钟图标

这个屏幕截图 firstsecond只点击第一个孩子然后滚动几次然后这个黑色是默认颜色

Answer 1

当您在适配器的 getView 方法中工作并且您在其中使用 IF 条件时，请尝试同时使用“else”。 在你的情况下，我可以看到 'if' 和 'else if'，而

其他

不见了。

if (b ==true)
{
             editor.putBoolean("time"+id,false);
             editor.commit();
             clock.setClockColor(R.color.material_brown_700);
}
else if (b == false)
{
          editor.putBoolean("time"+id,true);
          editor.commit();
          clock.setClockColor(R.color.material_green_700);
}

可以转换成

 if (b)
    {
                 editor.putBoolean("time"+id,false);
                 editor.commit();
                 clock.setClockColor(R.color.material_brown_700);
    }
    else 
    {
              editor.putBoolean("time"+id,true);
              editor.commit();
              clock.setClockColor(R.color.material_green_700);
    }
