个人认为ViewPager
类似于Listview
首先。在xml中定义ViewPager控件
1.ViewPager可以通过addView（layout）将制定的layout适配到ViewPager中
例如一下方式
mViews =
new ArrayList<View>();
mViews.add(getLayoutInflater().inflate(R.layout.layout_0,
null));
mViews.add(initView(listdoc));
mViews.add(initView2());
mViews.add(getLayoutInflater().inflate(R.layout.layout_0,
null));
mViewPager.setAdapter(new MyPagerAdapter());//
设置ViewPager的适配器
2.然后在类中将要用到控件通过Adapter适配到ViewPager中
for (int i = 0; i <
imageResId.length; i++) {
ImageView imageView = new ImageView(this);
imageView.setImageResource(imageResId[i]);
imageView.setScaleType(ScaleType.CENTER_CROP);
finalint t = i;
imageView.setOnClickListener(new OnClickListener() {
@Override
publicvoid onClick(View v) {
// TODO Auto-generated method stub
Toast.makeText(HomePage.this,
""+t, Toast.LENGTH_SHORT).show();
}
});
imageViews.add(imageView);
}
其实原理是一样的，定义一个List，然后将要部署到ViewPager中的View添加到List中
然后通过Adapter适配到ViewPager中
privateclass MyAdapter
extends PagerAdapter {
@Override
publicvoid destroyItem(View arg0,
int arg1, Object arg2) {
//
TODO Auto-generated method stub
((ViewPager) arg0).removeView((View) arg2);
//该方法在ViewPager滑动以后调用，
}
@Override
publicvoid finishUpdate(View arg0) {
//
TODO Auto-generated method stub
}
@Override
publicint getCount() {
//
TODO Auto-generated method stub
returnimageResId.length;
}
@Override
public Object instantiateItem(View arg0,
int arg1) {
//
TODO Auto-generated method stub
//ViewPager初始化时调用，将要部署的控件arg1（既List当中的position），部署到View中的arg0视图（positiion）中
((ViewPager) arg0).addView(imageViews.get(arg1));
returnimageViews.get(arg1);
}
@Override
publicvoid restoreState(Parcelable arg0, ClassLoader arg1) {
//
TODO Auto-generated method stub
}
@Override
public Parcelable saveState() {
//
TODO Auto-generated method stub
returnnull;
}
@Override
publicvoid startUpdate(View arg0) {
//
TODO Auto-generated method stub
}
@Override
publicboolean isViewFromObject(View arg0, Object arg1) {
return arg0 == arg1;
}
}
