如何根据不同的屏幕尺寸设置按钮

标签： java android xml button layout

伙计们，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，但是每当我在6.0或更高版本中打开我的应用程序时，然后在底部显示额外的空间，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。

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

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

您将拥有两个不同的垂直链（每列一个）：

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

这是xml：
