Android L的波紋觸摸效果?

[英]Android L ripple touch effect on shape?


I have a rounded rectangle with elevation that casts a shadow, just like in the example here: http://developer.android.com/preview/material/views-shadows.html#shadows

我有一個圓形的矩形,它的高程投射陰影,就像這里的例子:http://developer.android.com/preview/material/views-shadows.html#陰影。

Here is my shape:

這是我的形狀:

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <solid android:color="@android:color/white" />
    <corners android:radius="6dp" />
</shape>

I want to get the nice "ripple" touch effect that everything else has, but when that's set as the view's background, no touch feedback is given. The shape stays white.

我想要得到所有其他東西都具有的“波紋”觸摸效果,但是當它被設置為視圖的背景時,就不會給出觸摸反饋。形狀保持白色。

So, I made it into a layer-list:

所以,我把它做成了一個層次列表:

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <shape xmlns:android="http://schemas.android.com/apk/res/android"
            android:shape="rectangle">
            <solid android:color="@android:color/white" />
            <corners android:radius="6dp" />
        </shape>
    </item>
    <item android:drawable="?android:selectableItemBackground" />
</layer-list>

Now I get nice touch feedback when I tap it, but there's a problem.

當我點擊它時,我得到了很好的觸摸反饋,但是有一個問題。

The outline of the rounded rectangle shape was lost. It still draws the white rounded rectangle fine, but the shadow is cast as a non-rounded rectangle (square edges), and the ripple goes all the way out past the corners:

圓角矩形的輪廓丟失了。它仍然把白色圓角矩形畫得很好,但是陰影被投射成一個非圓角矩形(正方形的邊緣),漣漪一直延伸到角落:

Bad corners

It doesn't look too horrible on here, but on the device it's pretty ugly and off-putting.

它在這里看起來不太可怕,但在設備上它是相當丑陋和令人討厭的。

Is there a way to fix this? The Outline section of the first link seems to be what I want, but I can't figure out how to implement it.

有辦法解決這個問題嗎?第一個鏈接的Outline部分似乎是我想要的,但是我不知道如何實現它。

Try that one:

試試這個:

ripple.xml

ripple.xml

<?xml version="1.0" encoding="utf-8"?>
<ripple android:color="@color/COLOR_WHILE_PRESSING" xmlns:android="http://schemas.android.com/apk/res/android">
 <item android:drawable="@drawable/background"></item>
</ripple>

background.xml

background.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
 <solid android:color="@color/BACKGROUND_COLOR" />
 <corners android:radius="6dp" />
</shape>

Or maybe this post will help you: Android L FAB Button shadow

或者這篇文章可以幫助你:Android L FAB按鈕陰影

I explained there, how to implement the new FAB button, I also used the outline for that.

我在那里解釋了,如何實現新的FAB按鈕,我也使用了大綱。

Create button.xml in drawable folder

創建按鈕。xml在可拉的文件夾

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true" android:drawable="@color/colorPrimaryDark"/>
    <item android:drawable="@color/colorPrimary"/>
</selector>

Create button.xml in drawable-v21 folder

創建按鈕。xml drawable-v21文件夾中

<ripple xmlns:android="http://schemas.android.com/apk/res/android"
    android:color="?android:colorControlHighlight">
    <item android:drawable="@color/colorPrimary" />
</ripple>

you can set button.xml as background of your view.

你可以設置按鈕。xml作為視圖的背景。

<TextView android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginTop="8dp"
    android:background="@drawable/button"
    android:clickable="true"
    android:gravity="center"
    android:padding="16dp"
    android:text="Android Ripple Effect Custom"
    android:textColor="#fff"
    android:textSize="18sp" />

if you want custom color for ripple effect instead of default gray, then you can archive it by adding colorControlHighlight in your style.

如果您想要為紋波效果定制顏色,而不是默認的灰色,那么您可以通過在樣式中添加colorControlHighlight來存檔它。

<resources>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
        <item name="colorControlHighlight">@color/colorPrimaryDark</item>
    </style>

</resources>
