[英]Different layouts in a viewpager
I am trying to do something like the android market to show products from different categories. 我正在尝试像Android市场那样展示来自不同类别的产品。 I have implemented that behavior with this library, and it's all running good. 我已经使用这个库实现了这种行为,并且它运行良好。
What I want to do now is to have a list view in the page of the categories, and in each one of the others a grid view. 我现在要做的是在类别的页面中有一个列表视图,在其他每个列表中都有一个网格视图。 Of course, each one of them will have different sources of data. 当然,他们每个人都有不同的数据来源。
How can I achieve that ? 我怎样才能做到这一点? Does it have anything to do with adapters? 它与适配器有什么关系吗?

Else hope this code will be Helpful to you. 另外希望这段代码对您有所帮助。
@Override
public Object instantiateItem(View collection, int position) {
View v = new View(PatientView.this.getApplicationContext());
final LayoutInflater inflater = (LayoutInflater) PatientView.this
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
switch (position) {
case 0:
v = inflater.inflate(R.layout.patientp1,
(ViewGroup) null, false);
((Button) v.findViewById(R.id.pp1btnbck)).setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
finish();
}
});
break;
case 1:
v = inflater.inflate(R.layout.patientp2, null, false
);
break;
default:
TextView tv = new TextView(PatientView.this.context);
tv.setText("Page " + position);
tv.setTextColor(Color.WHITE);
tv.setTextSize(30);
v = tv;
break;
}
((ViewPager) collection).addView(v, 0);
return v;
}
I think you want extend FragmentPagerAdapter , override getItem
, and return the proper Fragment object (or ListFragment) depending on the index/position in the ViewPager. 我想你需要扩展FragmentPagerAdapter ,覆盖getItem
,并根据ViewPager中的索引/位置返回正确的Fragment对象(或ListFragment)。
In the layout xml for your Activity you should include a ViewPager
( <android.support.v4.view.ViewPager>
), and in your Activity onCreate
use the setAdapter
method of ViewPager
to assign your FragmentPagerAdapter
. 在你的活动布局XML,你应该包括ViewPager
( <android.support.v4.view.ViewPager>
并在活动onCreate
使用setAdapter
方法ViewPager
分配你的FragmentPagerAdapter
。
