Android线性布局未按预期扩展

Question

我在下面的代码中创建了一个带有图像，textview和2个图像按钮的正方形。

看起来像这样：

我想要它，以便文本总是在1行。方块的宽度需要扩展，因此它包含全文。在图像中，文本被裁剪。两个小按钮（信息和设置）需要在广场的角落。还有另一个问题，文本不是垂直居中的，应该是。

我无法让它看起来正确。有谁知道如何解决这个问题？

    TextView nametv = createNameView(context, fish.getName());

对于文字，请尝试以下答案：https://stackoverflow.com/a/2142968/2629065它会缩小文字范围，直到它符合您提供的参数。

你填充了顶部，增加了物品的高度，抵消了重力对齐。移除顶部衬垫并使用边距，或填充底部。
