Question

我在android XML布局中遇到问题，我在下面的xml布局中将自定义工具栏放在顶部，但有些工具栏如何被工具栏布局下方的Linarlayout重叠，因此我无法单击工具栏按钮，因为它位于另一个布局后面，请帮助我将其置于顶部，而不会影响XML设计的整体布局。

上述布局的设计看起来像这样。

非常感谢任何帮助。感谢您的阅读！

Answer 1

试试这个：

 Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
 toolbar.bringToFront();

Answer 2

如果你没有正确地布置它们，RelativeLayout会将它的所有子节点叠加在一起。

将包含工具栏的第一个LinearLayout设为id，例如机器人：ID =＆＃34; @ + ID /报头＆＃34;并添加android：layout_below =＆＃34; @ + id / header＆＃34;到RelativeLayout中的第二个LinearLayout。

RelativeLayout重叠
