android-satellite-menu实现点击主按钮，会弹出多个围绕着主按钮排列的子按钮，从而形成一个卫星弹出式菜单。子按钮弹出和消失的动画效果都很棒。这种弹出式菜单按钮应用在Path2.0中。

用法

在你的view xml中添加组件定义，如下示例：

xmlns:android="http://schemas.android.com/apk/res/android"

xmlns:sat="http://schemas.android.com/apk/res/android.view.ext"

android:layout_width="fill_parent"

android:layout_height="fill_parent"

android:orientation="vertical" >

android:id="@+id/menu"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_gravity="bottom|left"

android:layout_margin="8dp"

sat:satelliteDistance="170dp"

sat:mainImage="@drawable/ic_launcher"

sat:totalSpacingDegree="90"

sat:closeOnClick="true"

sat:expandDuration="500"/>

属性有：

satelliteDistance  The distance of items from the center button

totalSpacingDegree  The degree between the first and the last item.

closeOnClick  Defines if the menu shall collapse after clicking on a menu item.

expandDuration  The duration of expand and collapse operations in milliseconds.

当在你的View XML定义之后，可按以下代码添加子菜单：SatelliteMenu menu = (SatelliteMenu) findViewById(R.id.menu);

List items = new ArrayList();

items.add(new SatelliteMenuItem(4, R.drawable.ic_1));

items.add(new SatelliteMenuItem(4, R.drawable.ic_3));

items.add(new SatelliteMenuItem(4, R.drawable.ic_4));

items.add(new SatelliteMenuItem(3, R.drawable.ic_5));

items.add(new SatelliteMenuItem(2, R.drawable.ic_6));

items.add(new SatelliteMenuItem(1, R.drawable.ic_2));

Each menu item takes the ID of the item and the drawable resource for the item.

In order to listen clicks on items:

menu.setOnItemClickedListener(new SateliteClickedListener() {

public void eventOccured(int id) {

Log.i("sat", "Clicked on " + id);

}

});
