如何根据不同的屏幕尺寸设置按钮

Question

大家好，请检查我的代码，我无法设置具有不同屏幕尺寸的按钮，我在xml中设置按钮，但是每当我在5.0屏幕尺寸上启动应用程序时，它的效果都很好，但是每当我以6.0或更高版本打开应用程序时，在底部显示了额外的空间，我尝试了所有可能的解决方案，但仍然没有解决方案。 因此，请检查我的代码并查看屏幕截图，并为此提供正确的解决方案。

Answer 1

您应该删除LinearLayouts，并且应该为每个视图创建链。 您将具有三个不同的水平链（每行一个）：

• 父<-> imageButton <-> imageButton1 <->父
• 父<-> imageButton2 <-> imageButton3 <->父
• 父<-> imageButton4 <-> imageButton5 <->父

您将拥有两个不同的垂直链（每列一个）：

• 父<-> imageButton <-> imageButton2 <-> imageButton4 <->父
• 父<-> imageButton1 <-> imageButton3 <-> imageButton5 <->父

这是xml：
