SphereLayout

a layout which supports 3d rotate and enable its childview has z-depth for android

the effect is shown as below

I	II

Usage

XML

1. 在布局中配置SphereLayout, 设置半径"radius"和对齐方向"snapOrientation" (属性说明见XML attributes);

2. 添加childview, SphereLayout可以包含任意个childview ,每个childview都需要设置"layout_depth"属性,取值范围在 SphereLayout的"radius"正负范围内[ -radius , radius ] , 布局未旋转时,depth越大的childview视觉上越接近用户, depth 为负的childview一开始处于背面.

3. childview默认位于SphereLayout在x,y轴构建的平面上的中间位置，可添加margin使它相对中间位置进行偏移.

    <!-- sample -->
<com.thunderpunch.spherelayoutlib.layout.SphereLayout
    android:id="@+id/sl"
    android:layout_width="match_parent"
    android:layout_height="400dp"
    app:radius="90dp"
    app:snapOrientation="horizontal">

    <View
        android:id="@+id/v0"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@drawable/shape_oval_grey"
        app:layout_depth="30dp"
        app:layout_fitBounds="true" />

    <View
        android:id="@+id/v1"
        android:layout_width="50dp"
        android:layout_height="50dp"
        android:background="@drawable/shape_oval_black"
        app:layout_depth="-70dp" />

    <LinearLayout
        android:layout_width="90dp"
        android:layout_height="wrap_content"
        android:layout_marginRight="55dp"
        android:layout_marginTop="40dp"
        android:orientation="vertical"
        android:paddingBottom="5dp"
        android:paddingLeft="8dp"
        android:paddingRight="8dp"
        android:paddingTop="5dp"
        app:layout_depth="40dp">

    </LinearLayout>
</com.thunderpunch.spherelayoutlib.layout.SphereLayout>

Code

4. 使SphereLayout朝某个方向旋转一定的角度

SphereLayout sl = (SphereLayout) findViewById(R.id.sl);
sl.rotate(-40, 30);//朝x轴正方向逆时针旋转40度的方向，向内翻转30度

5. 反转 SphereLayout

sl.reverse(true);

XML attributes

• SphereLayout自身属性

<declare-styleable name="SphereLayout">
    <!-- 标记位于背面的视图是以Y轴水平翻转可到达正面，或是以X轴竖直翻转可到达正面 -->
    <attr name="snapOrientation">
        <enum name="horizontal" value="0" />
        <enum name="vertical" value="1" />
        <enum name="none" value="9" />
    </attr>
    <!-- 球体半径-->
    <attr name="radius" format="dimension|reference" />
    <!--是否隐藏位于背面的视图 -->
    <attr name="hideBack" format="boolean" />
</declare-styleable>    

• SphereLayout 直系子视图的布局参数

<declare-styleable name="SphereLayout_Layout">
   	<!--Z轴位置，必需设置-->
    <attr name="layout_depth" format="dimension|reference" /> 
  
  	<!--为true时，子视图会宽高适配当前所处depth的圆直径且无视自身margin属性-->
    <attr name="layout_fitBounds" format="boolean" /> 
</declare-styleable>

Extras

• 使SphereLayout和用户进行手势交互

SphereLayout sl = (SphereLayout) findViewById(R.id.sl);
sl.setOnTouchListener(new SLTouchListener(sl));

• 使SphereLayout依附于另一个SphereLayout的中心进行翻转 (待完善)

/**
 * @param sphereLayout 翻转依赖
 */
public void rotateDependsOn(SphereLayout sphereLayout) {
    mDependency = sphereLayout;
    mCheckedDependencyOffset = false;
    mDependency.mRotateListener = new OnRotateListener() {
        @Override
        public void onRotate(int direction, int degree) {
            rotate(direction, degree);
        }
    };
}
