我想将imageview和textview显示为图库中的Verticle项目，但不显示textview，并且在第一个项目和最后一个项目包含空格之前，如何删除此空间？
这是我的代码。

如何在图库的每个图像下方显示文字，我还想删除每个图库项目前后的空间。
答案 0 :(得分：0)
实际上在activity_filter.xml布局中，Gallery小部件的父布局（此处为LinearLayout）具有40dp的固定高度，如果增加它或使用权重处理它，它将显示{ {1}}。你可以看到，我把这个高度增加到TextView，它清楚地显示了100dp。这个空间即将到来，因为你已经TextView作为horizontalSpacing，如果你不想要列之间的空格，那就试着减少它。
<强>更新 -
我已更新我的答案以删除5dp周围的空格，此处我Gallery，现在RelativeLayout和Prev按钮与图库重叠。希望它能解决你的问题。
