XML Layout

Create a main layout which contains LinearLayout as parent view and add ListView as a child to it .

file : activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"

    <ListView
        android:id="@+id/list"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
     />
</LinearLayout>

Create list_item.xml inside layout directory ,this layout is used to defines the design of each row items in a list view

file : list_item.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"

Bean Class

Create a Bean Class RowItem which is used for setting and getting row data's of each items in ListView ( member_name , profile_pic_id, status, contactType ) .

file : RowItem.java
package com.pavan.mylistview;

public class RowItem {

 private String member_name;
 private int profile_pic_id;

 }

 public void setContactType(String contactType) {

}

Adapter

Create a custom adapter which extends BaseAdapter , this is used for inflating each row items of the listview

file :CustomAdapter.java

 }

 @Override
 public int getCount() {

 }

 @Override
 public Object getItem(int position) {
  return rowItems.get(position);
 }

 @Override
 public long getItemId(int position) {
  return rowItems.indexOf(getItem(position));
 }

 /* private view holder class */
 private class ViewHolder {
  ImageView profile_pic;
  TextView member_name;
  TextView status;
  TextView contactType;
 }

 @Override
 public View getView(int position, View convertView, ViewGroup parent) {

  ViewHolder holder = null;

  LayoutInflater mInflater = (LayoutInflater) context
    .getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
  if (convertView == null) {
   convertView = mInflater.inflate(R.layout.list_item, null);
   holder = new ViewHolder();

   holder.member_name = (TextView) convertView
     .findViewById(R.id.member_name);
   holder.profile_pic = (ImageView) convertView
     .findViewById(R.id.profile_pic);
   holder.status = (TextView) convertView.findViewById(R.id.status);
   holder.contactType = (TextView) convertView
     .findViewById(R.id.contact_type);

Activity

Finally In the main activity inside the onCreate method set the content of the view with main layout(R.layout.activity_main) which is defined above and set the above defined custom adapter for ListView .

file : MainActivity.java
package com.pavan.mylistview;

import android.os.Bundle;

import android.widget.Toast;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ListView;

public class MainActivity extends Activity implements OnItemClickListener {

 String[] member_names;
 TypedArray profile_pics;
 String[] statues;
 String[] contactType;

 List<RowItem> rowItems;
 ListView mylistview;

 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);

  rowItems = new ArrayList<RowItem>();

  member_names = getResources().getStringArray(R.array.Member_names);

  profile_pics = getResources().obtainTypedArray(R.array.profile_pics);

  statues = getResources().getStringArray(R.array.statues);

  contactType = getResources().getStringArray(R.array.contactType);

   RowItem item = new RowItem(member_names[i],
     profile_pics.getResourceId(i, -1), statues[i],
     contactType[i]);
   rowItems.add(item);
  }

  mylistview = (ListView) findViewById(R.id.list);
  CustomAdapter adapter = new CustomAdapter(this, rowItems);
  mylistview.setAdapter(adapter);
  profile_pics.recycle();
  mylistview.setOnItemClickListener(this);

 }

 @Override

Android GPS Map With Movable Marker with Map type

1.First step to import PLAYSERVICE file from sdk/extras/google/lib/google_play_lib project

2.Create new Android Project then select new project and right click select PROPERTIES

then ANDROID and add imported lib project to this new created project finally click OK button.

3.Create GOOGLE API CONSOLE account and create new project and create new API KEY for google map project

 4.Eclipse  ->Window->android->build   then copy the SHA1 key and add your

 package name then generate api key
then do it following
