Android衛星菜單：android-satellite-menu

android-satellite-menu實現點擊主按鈕，會彈出多個圍繞着主按鈕排列的子按鈕，從而造成一個衛星彈出式菜單。子按鈕彈出和消失的動畫效果都很棒。這種彈出式菜單按鈕應用在Path2.0中。

用法

在你的view xml中添加組件定義，以下示例：

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout
    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.view.ext.SatelliteMenu
        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"/>
 
</FrameLayout>

屬性有：

• 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.

當在你的View XML定義以後，可按如下代碼添加子菜單：

SatelliteMenu menu = (SatelliteMenu) findViewById(R.id.menu);
List<SatelliteMenuItem> items = new ArrayList<SatelliteMenuItem>();
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);
  }
});
