最近也在做下载平台，仿91做了个挖宝功能，现在就来说下浮动金币效果
先实现GoldApplication继承Application
View Code public class GoldApplication extends Application { private WindowManager.LayoutParams wmParams=new WindowManager.LayoutParams(); public WindowManager.LayoutParams getWmParams(){ return wmParams; } } 再实现金币类，可以拖动，自动靠边。如果程序结束或Home键回到桌面，就调用dismiss，不然的话金币会一直在桌面上哦。
View Code public class GoldIcon extends LinearLayout { private float mTouchRawX; private float mTouchRawY; private GestureDetector gestureDetector; private ImageButton gold; private WindowManager wm = (WindowManager) getContext().getApplicationContext().getSystemService(Context.WINDOW_SERVICE); //此wmParams变量为获取的全局变量，用以保存悬浮窗口的属性 private WindowManager.LayoutParams wmParams = ((GoldApplication)getContext().getApplicationContext()).getWmParams(); private int width=0,height=0;//控件宽高 private int DW=0,DH=0,MW=0;//屏幕宽高，屏幕宽的一半 public GoldIcon(Context context) { super(context); init(context); DW=BitmapTools.WH[0]; DH=BitmapTools.WH[1]; MW=DW/2; } private void init(Context context) { gestureDetector = new GestureDetector(context, gestureListener); View view = View.inflate(context,R.layout.gold_floatlayout,null); gold=(ImageButton) view.findViewById(R.id.gold); gold.setOnClickListener(onClick); gold.setOnTouchListener(frameOnTouchListener); this.addView(view); } final static int MESSAGE_MOVE = 0x1001; final static int MESSAGE_DOWN = 0x1002; final static int MESSAGE_UP = 0x1003; Handler mHandler = new Handler() { @Override public void handleMessage(Message msg) { switch (msg.what) { case MESSAGE_MOVE: updateViewPosition(); break; case MESSAGE_DOWN: break; case MESSAGE_UP: updateUpViewPosition(); break; default: } } }; // 点击Listener OnTouchListener frameOnTouchListener = new OnTouchListener() { float x,y; @Override public boolean onTouch(View v, MotionEvent event) { if (null == gestureDetector || null == event) { return false; } switch(event.getAction()) { case MotionEvent.ACTION_DOWN: x=event.getRawX(); y=event.getRawY(); break; case MotionEvent.ACTION_UP://松手时候靠边 if(Math.abs(x-event.getRawX())>10&&Math.abs(y-event.getRawY())>10) { new Thread(new Run()).start(); return true; } else { return false; } } return gestureDetector.onTouchEvent(event); } }; // 手势识别 GestureDetector.OnGestureListener gestureListener = new GestureDetector.OnGestureListener() { @Override public boolean onDown(MotionEvent e) { mTouchRawX = e.getX(); mTouchRawY = e.getY(); // mHandler.sendEmptyMessage(MESSAGE_MOVE); return false; } @Override public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) { return true; } @Override public void onLongPress(MotionEvent e) { // TODO Auto-generated method stub // Log.d("OnGestureListener", "onLongPress"); } @Override public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX, float distanceY) { mTouchRawX = e2.getRawX(); mTouchRawY = e2.getRawY(); mHandler.sendEmptyMessage(MESSAGE_MOVE); return true; } @Override public void onShowPress(MotionEvent e) { // Log.d("OnGestureListener", "onShowPress"); } @Override public boolean onSingleTapUp(MotionEvent e) { return false; } }; public void show() { gold.setVisibility(View.VISIBLE); } public void dismiss() { gold.setVisibility(View.GONE); } private void updateUpViewPosition() { wm.updateViewLayout(this, wmParams); } private void updateViewPosition() { // 更新浮动窗口位置参数 getWH(); wmParams.x = (int) mTouchRawX-(width); wmParams.y = (int) mTouchRawY-(height); wm.updateViewLayout(this, wmParams); } class Run implements Runnable { @Override public void run() { while(wmParams.x>=0&&wmParams.x+width<=DW) { setWelt(); try { Thread.sleep(3); } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); } } mHandler.sendEmptyMessage(MESSAGE_UP); } } private void setWelt() { if(wmParams.x+width/2 在要程序启动的首个Activity中
