New Google Now and Google+ card interface
提问by HBG
Google Now and Google+ (Android) both make use of a card-like interface.
Google Now 和 Google+ (Android) 都使用类似卡片的界面。
I was wondering if anyone had any idea how this interface can be replicated on Android.
我想知道是否有人知道如何在 Android 上复制此界面。
They both have quite interesting animations for displaying new cards too; any thoughts would be great.
它们都有非常有趣的动画来展示新卡片；任何想法都会很棒。

Heres a code snippet
这是一个代码片段
@Override
public void onGlobalLayout() {
getViewTreeObserver().removeGlobalOnLayoutListener(this);
final int heightPx = getContext().getResources().getDisplayMetrics().heightPixels;
boolean inversed = false;
final int childCount = getChildCount();
for (int i = 0; i < childCount; i++) {
View child = getChildAt(i);
int[] location = new int[2];
child.getLocationOnScreen(location);
if (location[1] > heightPx) {
break;
}
if (!inversed) {
child.startAnimation(AnimationUtils.loadAnimation(getContext(),
R.anim.slide_up_left));
} else {
child.startAnimation(AnimationUtils.loadAnimation(getContext(),
R.anim.slide_up_right));
}
inversed = !inversed;

Take a look at http://ryanharter.com/blog/2013/01/31/how-to-make-an-android-card-list/
看看http://ryanharter.com/blog/2013/01/31/how-to-make-an-android-card-list/
Copy of the example:
示例副本：
/res/drawable/bg_card.xml:
/res/drawable/bg_card.xml：
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle"
android:dither="true">
<corners android:radius="2dp"/>
<solid android:color="#ccc" />
</shape>
</item>
<item android:bottom="2dp">
<shape android:shape="rectangle"
android:dither="true">
<corners android:radius="2dp" />
<solid android:color="@android:color/white" />
<padding android:bottom="8dp"
android:left="8dp"
android:right="8dp"
android:top="8dp" />
</shape>
</item>
</layer-list>
Use it as the background of your layout:
将其用作布局的背景：
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="?android:attr/listPreferredItemHeight"
android:padding="12dp">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginLeft="6dp"
android:layout_marginRight="6dp"
android:layout_marginTop="4dp"
android:layout_marginBottom="4dp"
android:background="@drawable/bg_card">
<!-- Card Contents go here -->
</LinearLayout>
</FrameLayout>

Use the CardView from the Google Compatibility library (from Android 2.1+):
使用 Google 兼容性库中的 CardView（来自 Android 2.1+）：
<!-- A CardView that contains a TextView -->
<android.support.v7.widget.CardView
xmlns:card_view="http://schemas.android.com/apk/res-auto"
android:id="@+id/card_view"
android:layout_gravity="center"
android:layout_width="200dp"
android:layout_height="200dp"
card_view:cardCornerRadius="4dp">
<TextView
android:id="@+id/info_text"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</android.support.v7.widget.CardView>

The card look and feel shouldn't be hard. You just need a ListView without dividers and your list view items should have a margin.
卡片的外观和感觉应该不难。您只需要一个没有分隔符的 ListView 并且您的列表视图项应该有一个边距。
Like this:
像这样：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_margin="16dp"
android:layout_height="wrap_content"
android:background="@android:color/background_light">
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:paddingTop="16dp"
android:paddingRight="16dp"
android:paddingLeft="16dp"
android:text="Title"
android:textSize="18dp"
android:textColor="@android:color/primary_text_holo_light"
/>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:paddingRight="16dp"
android:paddingLeft="16dp"
android:text="Subtitle"
android:textSize="14dp"
android:textColor="@android:color/primary_text_holo_light"
/>
<ImageView android:layout_marginTop="16dp"
android:layout_marginBottom="16dp"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="@drawable/background"/>
</LinearLayout>

Have the same need, and have started investigating a bit. I've been looking at the apktool output I've been able to get from the com.google.android.googlequicksearchbox apk. (no sources only the res xmls)
有同样的需求，已经开始研究了一下。我一直在查看能够从 com.google.android.googlequicksearchbox apk 获得的 apktool 输出。（没有来源只有 res xmls）
This layout (at_place_card.xml) is used for displaying a location. It has three text lines and two actions buttons (details and checkin) on the right and an image on the left.
此布局 (at_place_card.xml) 用于显示位置。它的右侧有三个文本行和两个操作按钮（详细信息和签到），左侧有一个图像。
Unfortunately, I am not able to get any style information out from the apk, so the font size, dimensions and colors are just guesses.
不幸的是，我无法从 apk 中获取任何样式信息，因此字体大小、尺寸和颜色只是猜测。

Update: Was able to get some style information also now. If you're interested here is a zip file with the information I have currently (some resource files from google now). https://dl.dropbox.com/u/4379928/android/googlenow2.zip
更新：现在也可以获得一些样式信息。如果您有兴趣，这里有一个 zip 文件，其中包含我目前拥有的信息（现在来自 google 的一些资源文件）。 https://dl.dropbox.com/u/4379928/android/googlenow2.zip
