I have a button inside the included layout, how can I access the button? I don't know the id! How can I define the OnClickListener...?

请帮忙...

推荐答案

包含标签的 id 被分配给包含布局的根视图.首先使用 findViewByid 获取对该视图的引用.然后您可以在该特定视图上调用 findViewById 以获取对布局内视图的引用.所以:

The id you have with the include tag is assigned to the root View of the included layout. First get a reference to that View using findViewByid. Then you can call findViewById on that specific View to get a reference to a View inside the layout. So:

View myLayout = findViewById( R.id.cell1 ); // root View id from that link
View myView = myLayout.findViewById( R.id.someinnerview ); // id of a view contained in the included file
