现在很多软件都有悬浮框功能，比如Facebook，体验效果极佳。

先下载体验下悬浮窗吧，apk地址：  http://download.csdn.net/detail/zz7zz7zz/6454107

其他不说，直接步入正题看看具体的实现吧。

一、效果图：

二、实现知识点：

1.     WindowManager

addView(View view, LayoutParams params) ，添加一个悬浮窗

updateViewLayout(View view, LayoutParams params)，要使悬浮窗做出改变，需通过改变params的属性，并调用此方法更新。

removeView()移除一个悬浮窗。

2.  WindowManager.LayoutParams属性的设置。

WindowManager.LayoutParams mParams=new WindowManager.LayoutParams();

mParams.type=WindowManager.LayoutParams.TYPE_PHONE;//悬浮窗的类型

mParams.format= PixelFormat.RGBA_8888;  //效果为透明

mParams.flags=

WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL|WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE; //悬浮窗的行为，比如说不可聚焦，不可触摸，全屏对等

mParams.width=100;//指定悬浮窗的宽度

mParams.height=100;//指定悬浮窗的高度。

mParams.gravity=Gravity.LEFT|Gravity.TOP; //悬浮窗的对齐方式

mParams.x=0;  //悬浮窗的横坐标

mParams.y=0;//悬浮窗的纵坐标

3.  其他一些动画效果，通过重写View或者使用
SurfaceView作为补间动画。

public interface IAnimation
{
	public abstract void onAnimStart();
	public abstract void onAnimDraw(SurfaceHolder holder);
	public abstract void onAnimEnd();
}

具体的动画见com.open.tooltip.anim包下的具体实现类

4. 用Service 来控制动画

三、具体代码

1.  AndroidManifest.xml中的配置

权限：
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>
<uses-permission android:name="android.permission.GET_TASKS"/>

其他配置：
<!-- 悬浮框 开始 -->
<meta-data android:name="tooltipdata" android:value="com.open.MainActivity" />
<service android:name="com.open.tooltip.TooltipService"  android:exported="false">
</service>
<!-- 悬浮框 接收 -->

2.ChatBall，悬浮的小球

package com.open.tooltip;

import android.content.Context;
import android.graphics.Rect;
import android.os.Bundle;
import android.util.AttributeSet;
import android.view.MotionEvent;
import android.view.View;
import android.widget.ImageView;

/**
 * 小球
 * @author DexYang
 *
 */
public class ChatBall extends ImageView{
	
	private final String TAG="ChatBall";

	public ChatBall(Context context, AttributeSet attrs, int defStyle) {
		super(context, attrs, defStyle);
		init(context);
	}

	public ChatBall(Context context, AttributeSet attrs) {
		super(context, attrs);
		init(context);
	}

	public ChatBall(Context context) {
		super(context);
		init(context);		
	}
	
	private void init(Context context)
	{
		this.setImageResource(R.drawable.tooltip_icon_f);
		this.setOnTouchListener(onTouchListener);
	}
	
	private OnTouchListener onTouchListener=new OnTouchListener() {

		private boolean isMove=false;
		private Rect mViewRect=new Rect();
		
		@Override
		public boolean onTouch(View v, MotionEvent event) {

			switch(event.getAction())
			{
				case MotionEvent.ACTION_DOWN:
					isMove=false;
					
					//有些机子上调用下面代码无效
//					int[] location = new int[2];
//					v.getLocationOnScreen(location);
//					mViewRect.set(location[0], location[1], location[0]+TooltipMgr.getInstance().getBallWidth(), location[1]+TooltipMgr.getInstance().getBallHeight());
					
					int left=TooltipMgr.getInstance().src[0]-TooltipMgr.getInstance().getBallWidth()/2;
					int top=TooltipMgr.getInstance().src[1]-TooltipMgr.getInstance().getBallHeight()/2;
					mViewRect.set(left, top, left+TooltipMgr.getInstance().getBallWidth(), top+TooltipMgr.getInstance().getBallHeight());
					
					break;
					
				case MotionEvent.ACTION_MOVE:
					if(!isMove)
					{
						int _lastX = (int) event.getRawX();
						int _lastY = (int) event.getRawY()-TooltipMgr.getInstance().getStatusBarHeight(getContext());
						if(!mViewRect.contains(_lastX, _lastY))
						{
							isMove=true;
							
							if(ToolTipConfig.isUseSurfaceView)
							{
								Bundle mBundle=new Bundle();
								mBundle.putIntArray("data", new int[]{_lastX,_lastY});
								TooltipMgr.getInstance().updateUI(getContext(), TooltipMgr.STATUS_BALL_DRAG, mBundle);
							}
							TooltipMgr.getInstance().updataChatBall(event);
						}
					}
					else
					{
							TooltipMgr.getInstance().updataChatBall(event);
					}
					break;
					
				case MotionEvent.ACTION_UP:
				case MotionEvent.ACTION_CANCEL:
					
					if(isMove)
					{
						TooltipMgr.getInstance().updataChatBall(event);
					}
					else
					{
						TooltipMgr.getInstance().updateUI(getContext(), TooltipMgr.STATUS_CHATWINDOW_OPEN, null);
					}
					break;
			}
			return true;
		}
	};
}

			}
		}

	}
	
	/**

	};
	
	private boolean isContain()
	{

	}
	
	@Override
	public void onConfigurationChanged(Configuration newConfig) {
