Android - ViewPager
ViewPager (视图滑动切换工具)
<android.support.v4.view.ViewPager
android:id="@+id/viewPager"
android:layout_centerHorizontal="true"
android:layout_width="230dp"
android:layout_height="150dp">
</android.support.v4.view.ViewPager>
PagerAdapter 适配器
class MyPagerAdapter extends PagerAdapter {
public List<View> vieLists;
public MyPagerAdapter(List<View> vieLists) {
this.vieLists = vieLists;
}
@Override
public int getCount() {
return vieLists.size();
}
@Override
public boolean isViewFromObject(View view, Object object) {
return view==object;
}
@Override
public void destroyItem(ViewGroup container, int position, Object object) {
container.removeView(vieLists.get(position)); 、
}
@Override
public Object instantiateItem(ViewGroup container, int position) {
container.addView(vieLists.get(position)); //每次滑动返回一个View
return vieLists.get(position);
}
}
为ViewPager设置适配器:
//ViewPget
ViewPager viewPager = (ViewPager) findViewById(R.id.viewPager);
List<View> list=new ArrayList<>();
ImageView iv1 = new ImageView(this);
Glide.with(this).load(R.drawable.shanghai1).into(iv1);
ImageView iv2 = new ImageView(this);
Glide.with(this).load(R.drawable.shanghai2).into(iv2);
ImageView iv3 = new ImageView(this);
Glide.with(this).load(R.drawable.shanghai3).into(iv3);
// 直接添加ImageView
list.add(iv1);
list.add(iv2);
list.add(iv3);
// 添加布局View
// LayoutInflater li=getLayoutInflater();
// list.add(li.inflate(R.layout.tab1_layout,null,false));
// list.add(li.inflate(R.layout.tab2_layout,null,false));
//设置适配器
MyPagerAdapter adapter=new MyPagerAdapter(list);
viewPager.setAdapter(adapter);
