Fetch Name,Email and Photo from contacts and Send Email on selected

Hello all,

Today I am going to share the code to fetch contact detail(name,email,pic) using Content Provider.

Overview :

To fetch email address ,name and photo,I have made a layout having a listview  named :

fetch_contacts_layout.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:background="#FF00BB" >
    

    <TextView android:layout_width="match_parent"
        android:layout_height="50sp"
        android:background="#FFFFFF"
        android:text="FETCH Contacts"
        android:gravity="center_vertical|center_horizontal"
        android:textColor="#000000"
        android:textSize="18sp"
        android:id="@+id/txt_header_fetchcontactlayout"/>

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

</LinearLayout>

->Again we have to design a listview item to show single item of listview .I have named it:
contact_listitem.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:layout_width="fill_parent"
              android:layout_height="70dp"
              android:layout_gravity="center_horizontal"
              android:orientation="horizontal"
              android:background="#F0F0F0">
<RelativeLayout android:layout_width="match_parent"
    android:layout_height="70dp"
    android:id="@+id/layout_cover">
    <ImageView
            android:id="@+id/icon_contactlistitem"
            android:src="@drawable/ic_launcher"
             android:layout_centerVertical="true"
            android:layout_width="50dp"
            android:layout_height="50dp"
            
            android:layout_marginLeft="10dp" />
    <LinearLayout
            android:orientation="vertical"
            android:layout_gravity="center_vertical"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_centerVertical="true"
            android:layout_toRightOf="@+id/icon_contactlistitem"
            android:layout_marginLeft="15dp" >
        <TextView
                android:id="@+id/name_contactlistitem"
                android:text="test"
                android:textColor="#333"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:textSize="15sp" />
     
    </LinearLayout>
   </RelativeLayout>

</RelativeLayout>

->Now let's move to the main activity ,I have named it FetchEmailActivity.java

import java.util.ArrayList;
import android.app.Activity;
import android.app.AlertDialog;
import android.app.ProgressDialog;
import android.content.ContentResolver;
import android.database.Cursor;
import android.os.Build;
import android.os.Bundle;
import android.provider.ContactsContract;
import android.util.Log;
import android.widget.ListView;
import android.widget.TextView;

public class FetchEmailActivity extends Activity{

ListView list;
TextView txt_header;
ProgressDialog dlg;
String image_uri = "";
ArrayList<String> mImg =  null,mEmial,mPhone = null;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.fetch_contacts_layout);
txt_header = (TextView)findViewById(R.id.txt_header_fetchcontactlayout);
 list = (ListView)findViewById(R.id.list_fetchcontactlayout);
 txt_header.setText("Email");
LoadContacts();

}
private void LoadContacts() {
if (Build.VERSION.SDK_INT >= 11 ) {
  dlg = new ProgressDialog(FetchEmailActivity.this,AlertDialog.THEME_HOLO_LIGHT );
     } else {
        dlg = new ProgressDialog(FetchEmailActivity.this);
       }
       dlg.setMessage("Loading...");
       dlg.show();
mEmial = new ArrayList<String>();
mPhone = new ArrayList<String>();
mImg = new ArrayList<String>();
       ContentResolver cr = FetchEmailActivity.this.getContentResolver();
    
       Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,null, null, null, null);
       if (cur.getCount() > 0) {
           while (cur.moveToNext()) {
               String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
               Cursor cur1 = cr.query( 
                       ContactsContract.CommonDataKinds.Email.CONTENT_URI, null,
                       ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = ?", 
                               new String[]{id}, null); 
               while (cur1.moveToNext()) { 
                   String name=cur1.getString(cur1.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
                   Log.e("Name :", name);
                   String email = cur1.getString(cur1.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
                   Log.e("Email", email);
                   image_uri = cur1
                   .getString(cur1
                     .getColumnIndex(ContactsContract.CommonDataKinds.Email.PHOTO_URI));
                   if(email!=null){
                    mEmial.add(name);
                    mPhone.add(email);
                   }
                   if (image_uri!=null) {
                    if (image_uri.equals("")) {
                    mImg.add("no");
}
                   else
                   {
                    mImg.add(image_uri);
                   }
}
                   else {
                    mImg.add("no");
}
                  
                   
               } 
               cur1.close();
           }
           dlg.dismiss();
          list.setAdapter(null);
           list.setAdapter(new SimpleContactAdapter(FetchEmailActivity.this,mEmial,mPhone,mImg));
       }
       
}


}

->->Here is the design for SimpleContactAdapter.java   The adapter which is used to show the items in listview :

import java.util.ArrayList;
import com.nostra13.universalimageloader.core.DisplayImageOptions;

public class SimpleContactAdapter extends BaseAdapter{
 
private class ViewHolder {

}
private ImageLoader imageLoader  = ImageLoader.getInstance();

.displayer(new FadeInBitmapDisplayer(300))
.build();
private LayoutInflater mLayoutInflater = null;
private Activity activity;
private ViewHolder holder;

ArrayList<String>  Showname,ShowEmail,ShowImg;

public SimpleContactAdapter(Activity activity2,
ArrayList<String> showname,ArrayList<String> email, ArrayList<String> mImg) {
this.activity = activity2;
this.Showname = showname;
this.ShowEmail = email;
this.ShowImg = mImg;
mLayoutInflater = (LayoutInflater)activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
imageLoader.init(ImageLoaderConfiguration.createDefault(activity));
    
}

@Override
public int getCount() {
return Showname.size();
}

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

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

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

if (convertView == null) {
convertView = mLayoutInflater.inflate(R.layout.contact_listitem, null);

holder = new ViewHolder();
holder.lnCover = (RelativeLayout)convertView.findViewById(R.id.layout_cover);
holder.tvTitle= (TextView) convertView.findViewById(R.id.name_contactlistitem);
holder.img_album = (ImageView)convertView.findViewById(R.id.icon_contactlistitem);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.tvTitle.setText("Name: "+Showname.get(position)+" \n Email: "+ShowEmail.get(position));

if (ShowImg.get(position).equals("no")) {
holder.img_album.setImageResource(android.R.drawable.picture_frame);
}
else {
imageLoader.displayImage(ShowImg.get(position),holder.img_album, options);

}
          holder.lnCover.setOnClickListener(new View.OnClickListener() {

@Override
public void onClick(View v) {
Intent intent = new Intent(Intent.ACTION_SEND);
            intent.setType("text/html");
            intent.putExtra(Intent.EXTRA_EMAIL, ShowEmail.get(position));
            intent.putExtra(Intent.EXTRA_SUBJECT, "Hood Scanner Application");
            activity.startActivity(Intent.createChooser(intent, "Send Email"));
}
});
return convertView;
}

}



->Here I have used  Android-Universal-Image-Loader to load the image ,you can replace it with another Image Loader.

->next step will be  add user-permission in Menifest file :

 <uses-permission android:name="android.permission.READ_CONTACTS"/>

->That's all I have attached the screen shot below of this demo:
