Hello Friends,

There are two or many more header listview in android. So Today we are discussed about the two header of android.

And See Also Simple Listview Display In Android Device.

So This are the all java and xml file given below. and this are the very useful projects.

main.xml

<?xml version="1.0" encoding="utf-8"?>
<ListView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/list"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:drawSelectorOnTop="true"
/>

header.xml

<TextView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center" android:scrollbars="none"
style="?android:attr/listSeparatorTextViewStyle" />

Now The java File code Given below.

SectionedAdapter .java

package com.android.listview;

import android.view.View;
import android.view.ViewGroup;
import android.widget.Adapter;
import android.widget.BaseAdapter;
import java.util.ArrayList;
import java.util.List;

abstract public class SectionedAdapter extends BaseAdapter {
abstract protected View getHeaderView(String caption, int index,
View convertView, ViewGroup parent);

private List

sections = new ArrayList

();
private static int TYPE_SECTION_HEADER = 1;

public SectionedAdapter() {
super();
}

public void addSection(String caption, Adapter adapter) {
sections.add(new Section(caption, adapter));
}

public Object getItem(int position) {
for (Section section : this.sections) {
if (position == 0) {
return (section);
}

int size = section.adapter.getCount() + 1;

if (position <>
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 <>
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);
}

@Override
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 <>
return (section.adapter.getView(position - 1, convertView,
parent));
}

position -= size;
sectionIndex++;
}

return (null);
}

@Override
public long getItemId(int position) {
return (position);
}

class Section {
String caption;
Adapter adapter;

Section(String caption, Adapter adapter) {
this.caption = caption;
this.adapter = adapter;
}
}
}

Selection.java


package com.commonsware.android.listview;

import android.app.ListActivity;
import android.content.Context;
import android.os.Bundle;
import android.view.View;
import android.view.ViewGroup;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.TextView;
import java.util.Arrays;
import java.util.Collections;
import java.util.List;

public class SectionedDemo extends ListActivity {
private static String[] items = { "US", "UK", "CANADA", "JAPAN", "SINGAPORE",
"INDIA", "CHINA" };

private static String[] Sect = { "GOOGLE", "FACEBOOK","DELL" };

private static String[] Doc = { "FRONT", "TOP","BACK" };

@Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.main);

adapter.addSection("step 1", new ArrayAdapter(this,
android.R.layout.simple_list_item_1, items));

adapter.addSection("Step 2", new ArrayAdapter(this,
android.R.layout.simple_list_item_1, Sect));

adapter.addSection("Step 3", new ArrayAdapter(this,
android.R.layout.simple_list_item_1, Doc));

setListAdapter(adapter);
}

SectionedAdapter adapter = new SectionedAdapter() {
protected View getHeaderView(String caption, int index,
View convertView, ViewGroup parent) {
TextView result = (TextView) convertView;

if (convertView == null) {
result = (TextView) getLayoutInflater().inflate(
R.layout.header, null);
}

result.setText(caption);

return (result);
}
};
}


And Now The output given below.
