Android(安卓)页面手势滑动

用了android-support-v4 架包里面功能很强大,还没怎么仔细研究,如有所需去研究官方文档吧,下面上截图

xml中使用架包里的ViewPager组件

<android.support.v4.view.ViewPager        android:id="@+id/viewPager"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_gravity="center" />

绑定ViewPater之前需要一个List用来存放多个页面的View

Activity中对ViewPater进行适配器绑定

PagerAdapter apdter = new PagerAdapter() {@Overridepublic boolean isViewFromObject(View arg0, Object arg1) {return arg0 == arg1;}@Overridepublic int getCount() {return mViewArr.size();}@Overridepublic void destroyItem(ViewGroup container, int position,Object object) {((ViewPager) container).removeView(mViewArr.get(position));}@Overridepublic Object instantiateItem(ViewGroup container, int position) {((ViewPager) container).addView(mViewArr.get(position));return mViewArr.get(position);}};viewPager.setAdapter(apdter);

然后就大功告成了

如需捕获页面滑动事件对ViewPater设置setOnPageChangeListener事件在onPageSelected方法中调用即可

viewPager.setOnPageChangeListener(new OnPageChangeListener() {@Overridepublic void onPageSelected(int arg0) {}
