Android基于ViewPager Fragment实现选项卡

} public class MyOnPageChangeListener implements OnPageChangeListener{

private int one = offset *2 +bmpW;//两个相邻页面的偏移量 @Override

public void onPageScrolled(int arg0, float arg1, int arg2) { // TODO Auto-generated method stub

} @Override

public void onPageScrollStateChanged(int arg0) { // TODO Auto-generated method stub

} @Override

public void onPageSelected(int arg0) { // TODO Auto-generated method stub

Animation animation = new TranslateAnimation(currIndex*one,arg0*one,0,0);//平移动画 currIndex = arg0;

animation.setFillAfter(true);//动画终止时停留在最后一帧，不然会回到没有执行前的状态 animation.setDuration(200);//动画持续时间0.2秒

image.startAnimation(animation);//是用ImageView来显示动画的 int i = currIndex + 1;

Toast.makeText(MainActivity.this, "您选择了第"+i+"个页卡", Toast.LENGTH_SHORT).show(); }

} @Override

public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present.

getMenuInflater().inflate(R.menu.main, menu); return true;

} }
