如何通过多个包含将 onclick 侦听器设置为线性布局中的所有项目
How to set onclick listeners to all items in linearlayout through multiple include's
我们正在构建 android 警报应用程序，并且对移动开发了解不多。所以问题是：我们有 days_of_the_week.xml 线性布局和水平星期几，included 在 days_pick.xml版式，此版式包含在activity_add_page.xml中。
我们希望能够以某种方式选择并突出显示用户在该组件中选择的日期。
不写这样的东西可以做到吗:
one_week.monday_tv.setOnClickListener{
it.setBackgroundColor(getColor(R.color.purple_active))
}

如您所见，我尝试使用 forEach 但没有用
您可以在 AddPageActivity.kt 中声明一个通用方法。如下所示：
fun onClickDayOfWeek(view: View) {
Log.d("TAG", "View Clicked having ID= " + view.id)
view.setBackgroundColor(getColor(R.color.purple_active))
}
然后像下面这样处理每个 view 的点击：
<TextView
android:id="@+id/monday_tv"
android:padding="5dp"
android:layout_margin="5dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/monday"
android:onClick="onClickDayOfWeek" /> <!-- handling click-->
<TextView
android:id="@+id/tuesday_tv"
android:padding="5dp"
android:layout_margin="5dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/tuesday"
android:onClick="onClickDayOfWeek" /> <!-- handling click-->

如您所见，我尝试使用 forEach 但没有用
您可以在 AddPageActivity.kt 中声明一个通用方法。如下所示：
fun onClickDayOfWeek(view: View) {
Log.d("TAG", "View Clicked having ID= " + view.id)
view.setBackgroundColor(getColor(R.color.purple_active))
}
然后像下面这样处理每个 view 的点击：
<TextView
android:id="@+id/monday_tv"
android:padding="5dp"
android:layout_margin="5dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/monday"
android:onClick="onClickDayOfWeek" /> <!-- handling click-->
<TextView
android:id="@+id/tuesday_tv"
android:padding="5dp"
android:layout_margin="5dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/tuesday"
android:onClick="onClickDayOfWeek" /> <!-- handling click-->
