以title控件为例
1.创建一个类继承LinearLayout
2.在activity.xml中引用:
<com.firstlinetestapp.ui.view.TitleLayout android:layout_width="match_parent" android:layout_height="wrap_content" />
3.编辑toolbar的控件事件:
class TitleLayout(context: Context, attrs: AttributeSet) : LinearLayout(context, attrs) { init { LayoutInflater.from(context).inflate(R.layout.title,this) title_back.onClick { val c = getContext() as Activity c?.finish() } title_edit.onClick { Toast.makeText(getContext(), "Clicked Edit button", Toast.LENGTH_SHORT).show() } } }
