一、前言
Android 实现卫星式菜单也叫弧形菜单，主要要做的工作如下：
1.动画的处理
2.自定义ViewGroup来实现卫星式菜单View
（1）自定义属性
a. 在attrs.xml中定义属性
b. 在布局中使用自定义属性
c. 在自定义View中读取布局文件中的自定义属性
（2）onMeasure 测量 child 即测量主按钮以及菜单项
（3）onLayout 布局 child 即布局主按钮以及菜单项
（4）设置主按钮的选择动画
a.为菜单项menuItem添加平移动画和旋转动画
b.实现菜单项menuItem的点击动画

二、实现
上面介绍了原理和效果图，下面来看看卫星菜单类的实现：
1.布局文件的实现

3.使用卫星式菜单类
package com.xc.xcskin;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Toast;
import com.xc.xcskin.view.XCArcMenuView;
import com.xc.xcskin.view.XCArcMenuView.OnMenuItemClickListener;
import com.xc.xcskin.view.XCGuaguakaView;
import com.xc.xcskin.view.XCGuaguakaView.OnCompleteListener;
/**
* 使用并测试自定义卫星式菜单View
* @author caizhiming
*
*/
public class XCArcMenuViewDemo extends Activity{
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.xc_arcmenu_view_demo);
XCArcMenuView view = (XCArcMenuView) findViewById(R.id.arcmenu);
view.setOnMenuItemClickListener(new OnMenuItemClickListener() {
@Override
public void onClick(View view, int pos) {
// TODO Auto-generated method stub
String tag = (String) view.getTag();
Toast.makeText(XCArcMenuViewDemo.this, tag, Toast.LENGTH_SHORT).show();
}
});
}
}
三、总结
Android实现自定义的卫星式菜单(弧形菜单)的内容到这就基本结束了，感兴趣的朋友们可以动手操作起来，只有自己实践了才能更深的理解，希望本文对大家能有所帮助。
