用activity做菜单

利用Activity做一个弹出式菜单

实现长按item弹出菜单
话不多说，看源码

	// 实现onTouchEvent触屏函数但点击屏幕时销毁本Activity

Item.java

package com.bjyz.test;

public class Item {

	private Boolean checkBox;
	public Item(Boolean checkBox){
		this.checkBox=checkBox;
	}

	public Boolean getCheckBox() {
		return this.checkBox;
	}


	public void setCheckBox(Boolean checkBox) {
		this.checkBox = checkBox;
	}
	
	
}
 

activity_main.xml

item.xml

menu.xml

注意要在AndroidManifest.xml文件中对MenuWindow Activity文件进行注册

在values 中的styles.xml添加Activity样式

同时添加进出动画

在res下新建anim文件夹，放入动画文件
push_bottom_in.xml

push_buttom_out.xml
