I achieved multiple header scenario using custom Section Adapter which is originally coded by CommonsWare, you can make section within listivew, like Books, Games and etc. check out below code.
Section Adapter:
package com.medplan.db;
import java.util.ArrayList;
import java.util.List;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Adapter;
import android.widget.BaseAdapter;
abstract public class SectionedAdapter extends BaseAdapter {
String TAG = "========SectionedAdapter============";
abstract protected View getHeaderView(String caption,
int index,
View convertView,
ViewGroup parent);
private List<Section> sections=new ArrayList<Section>();
private static int TYPE_SECTION_HEADER=0;
public SectionedAdapter() {
super();
sections.clear();
}
public void addSection(String caption, Adapter adapter) {
sections.add(new Section(caption, adapter));
}
public void clear() {
sections.clear();
notifyDataSetChanged();
}
public Object getItem(int position) {
for (Section section : this.sections) {
if (position==0) {
return(section);
}
int size=section.adapter.getCount()+1;
if (position<size) {
return(section.adapter.getItem(position-1));
}
position-=size;
}
return(null);
}
public int getCount() {
int total=0;
for (Section section : this.sections) {
total+=section.adapter.getCount()+1; // add one for header
}
return(total);
}
public int getViewTypeCount() {
int total=1; // one for the header, plus those from sections
for (Section section : this.sections) {
total+=section.adapter.getViewTypeCount();
}
return(total);
}
public int getItemViewType(int position) {
int typeOffset=TYPE_SECTION_HEADER+1; // start counting from here
for (Section section : this.sections) {
if (position==0) {
return(TYPE_SECTION_HEADER);
}
int size=section.adapter.getCount()+1;
if (position<size) {
return(typeOffset+section.adapter.getItemViewType(position-1));
}
position-=size;
typeOffset+=section.adapter.getViewTypeCount();
}
return(-1);
}
public boolean areAllItemsSelectable() {
return(false);
}
public boolean isEnabled(int position) {
return(getItemViewType(position)!=TYPE_SECTION_HEADER);
}
public View getView(int position, View convertView,
ViewGroup parent) {
int sectionIndex=0;
for (Section section : this.sections) {
if (position==0) {
return(getHeaderView(section.caption, sectionIndex,
convertView, parent));
}
int size=section.adapter.getCount()+1;
if (position<size) {
return(section.adapter.getView(position-1,convertView,parent));
}
position-=size;
sectionIndex++;
}
return(null);
}
public long getItemId(int position) {
return(position);
}
class Section {
String caption = null;
Adapter adapter = null;
Section(String caption, Adapter adapter) {
this.caption=caption;
this.adapter=adapter;
}
}
}
Within Activity make Section adapter object,check out below code:
final SectionedAdapter adapter =new SectionedAdapter()
{
protected View getHeaderView(String caption, int index, View convertView,ViewGroup parent)
{
result=(TextView)convertView;
if (convertView==null)
{
result=(TextView)getLayoutInflater().inflate(R.layout.section_header,null);
}
result.setText(caption);
// temp=caption;
// ind=index;
return(result);
}
};
section_header.xml
<?xml version="1.0" encoding="utf-8"?>
<TextView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="@color/black"
android:textColor="#FFFFFF"
android:ellipsize="end"
android:textSize="11sp"
style="?android:attr/listSeparatorTextViewStyle" />
<!-- android:background="#515050"-->
Within Activity add section as many as you want like below:
Note: userPic & medPic are name of arraylist.
adapter.addSection("section first", new EfficientAdapter(getApplicationContext(),usersPic));
adapter.addSection("section second", new EfficientAdapter(getApplicationContext(),medPic));
listview.setAdapter(adapter);
MergeAdapter. Turns out I can't. Thanks – Intervenient
