android – Spinner在选择项目后向下移动布局

2019-07-06 16:23:38  阅读：165  来源： 互联网

标签：android android-layout android-spinner


我有一个奇怪的问题.我在布局中添加了一个微调器.当我在微调器中选择一个项目时,微调器在布局中向下移动,导致页面中的垂直滚动.我不希望发生这种情况,因为这会导致我的页面上的按钮在滚动之前显示在屏幕上较少.

这里我在代码中使用微调器

            }
        }
    }
}

正如您在上面的屏幕截图中看到的那样,我指的是“添加礼物到包”按钮被隐藏.

解决方法:

你只需要指定微调器的高度,
