Android实现自定义的卫星式菜单(弧形菜单)详解-编程学习网

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;

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();
   }
  });
 }
}
