我有一个ViewPager设置,包含3个片段类和一个pageadapter类。
MainActivity类
package com.example.swipeview;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentManager;
import android.support.v4.view.PagerAdapter;
import android.support.v4.view.ViewPager;
public class MainActivity extends FragmentActivity {
ViewPager viewpager;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
viewpager = (ViewPager) findViewById(R.id.viewpagers);
com.example.swipeview.PagerAdapter padapter = new com.example.swipeview.PagerAdapter(getSupportFragmentManager());
viewpager.setAdapter(padapter);
}
}
PageAdapter类
package com.example.swipeview;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
public class PagerAdapter extends FragmentPagerAdapter {
public PagerAdapter(FragmentManager fm) {
super(fm);
// TODO Auto-generated constructor stub
}
@Override
public Fragment getItem(int arg0) {
// TODO Auto-generated method stub
switch(arg0){
case 0:
return new FragmentOne();
case 1:
return new FragmentTwo();
case 2:
return new FragmentThree();
default:
break;
}
return null;
}
@Override
public int getCount() {
// TODO Auto-generated method stub
return 3;
}
}
和我的第一个FragmentClass作为例子
package com.example.swipeview;
import com.example.swipeview.R;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
public class FragmentOne extends Fragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState){
return inflater.inflate(R.layout.fragment_one_layout, container, false);
}
}//end of class
我已尝试过我常用的方法在Activity类中创建一个listview,但这并不适用于片段类。我想知道是否有人可以告诉我如何将listview编码成片段类。
答案 0 :(得分:0)
使用自定义适配器(使用List作为源)的示例:
public class ItemsFragment extends Fragment {
/* Must be populated later. */
private final List<Item> items = new ArrayList<>();
private ItemAdapter adapter;
private ListView listView = null;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View layout = inflater.inflate(R.layout.fragment_items_list, container, false);
adapter = new ItemAdapter(this.getActivity(), items);
listView = (ListView) layout.findViewById(R.id.listview_items);
return layout;
}
@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
listView.setAdapter(adapter);
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Item currentItem = adapter.getItem(position);
// (...)
}
});
}
/* (...) */
}
