android 动画 fleep

从右向左滑动,tab页切换后的效果

主要代码1:继承TabHost覆写setCurrentTab(int index)方法

@Override
	public void setCurrentTab(int index) {
		//index为要切换到的tab页索引，currentTabIndex为现在要当前tab页的索引
		int currentTabIndex = getCurrentTab();
		
		//设置当前tab页退出时的动画
		if (null != getCurrentView()){//第一次进入MainActivity时，getCurrentView()取得的值为空
			if (currentTabIndex == (tabCount - 1) && index == 0) {//处理边界滑动
				getCurrentView().startAnimation(slideLeftOut);
			} else if (currentTabIndex == 0 && index == (tabCount - 1)) {//处理边界滑动
				getCurrentView().startAnimation(slideRightOut);
			} else if (index > currentTabIndex) {//非边界情况下从右往左fleep
				getCurrentView().startAnimation(slideLeftOut);
			} else if (index < currentTabIndex) {//非边界情况下从左往右fleep
				getCurrentView().startAnimation(slideRightOut);
			}
		}
		
		super.setCurrentTab(index);
		
		//设置即将显示的tab页的动画
		if (currentTabIndex == (tabCount - 1) && index == 0){//处理边界滑动
			getCurrentView().startAnimation(slideLeftIn);
		} else if (currentTabIndex == 0 && index == (tabCount - 1)) {//处理边界滑动
			getCurrentView().startAnimation(slideRightIn);
		} else if (index > currentTabIndex) {//非边界情况下从右往左fleep
			getCurrentView().startAnimation(slideLeftIn);
		} else if (index < currentTabIndex) {//非边界情况下从左往右fleep
			getCurrentView().startAnimation(slideRightIn);
		}
	}

2:实现OnGestureListener接口，覆写onFling()方法

@Override
	public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX,float velocityY) {
		if (e1.getX() - e2.getX() <= (-FLEEP_DISTANCE)) {//从左向右滑动
			currentTabID = tabHost.getCurrentTab() - 1;
			if (currentTabID < 0) {
				currentTabID = tabHost.getTabCount() - 1;
			}
		} else if (e1.getX() - e2.getX() >= FLEEP_DISTANCE) {//从右向左滑动
			currentTabID = tabHost.getCurrentTab() + 1;
			if (currentTabID >= tabHost.getTabCount()) {
				currentTabID = 0;
			}
		}
		tabHost.setCurrentTab(currentTabID);
		return false;
	}
