自定义控件事件

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()

        }
    }

}
