如何使在一个线性布局的连锁反应，没有覆盖其子项上的背景色？ [英] How to make a ripple effect over a linear layout, without overriding the background color on its children?

问题描述

我有一个LinearLayout中，看起来像这样。

I have a LinearLayout that looks like this.

我希望每个行点击。在的LinearLayout code为行看起来是这样的：

I want each row to be clickable. The LinearLayout code for a row looks like this:

    <LinearLayout
        style="@style/home_menu_item_container"
        android:id="@+id/home_menu_acronyms_button"
        >
        <ImageView
            style="@style/home_menu_item_left"
            android:background="@color/greyLight"

            />
        <TextView
            style="@style/home_menu_item_right"
            android:text="@string/home_menu_option_2"
            android:background="@color/grey"
            />
    </LinearLayout>

我怎样才能添加在整个行扩展（父）产生连锁反应 - 该行不只是一个孩子的看法？这里最棘手的部分是让纹波去了两个彩色一行。

How can I add a ripple effect that expands over the entire row (parent) - not just one child view in the row? The tricky part here is to let the ripple go over the two colored row.

推荐答案

这是一个有点复杂，那是你需要的，但我不认为还有另一种方式，...

你需要把你的ImageView成的ListView 让每一个 ImageView的是一个列表项，然后你可以设置纹波，但你还需要设置 drawSelectorOnTop =真正的否则将无法正常工作

It is a little bit complicated for that what you need but I don't think there is another way,...
You need to put your ImageView's into a ListView so that every ImageView is a ListItem and then you can set the ripple but you also need to set drawSelectorOnTop="true" otherwise it won't work correctly
