How to create custom font for Text View

Hi guys i am going to explain custom font for TextView

First We have create assets directory inside the main directory and then create fonts directory inside the assets main->assets->font->  then put the font file inside the font directory

Then create the below file inside any one package. The below file created in com.crm.common package

package com.crm.Common;

import android.content.Context;
import android.graphics.Typeface;
import android.util.AttributeSet;
import android.widget.TextView;

/** * Created by Ashok on 11/19/2015. */public class CustomReqularTextView extends TextView {
    public static Typeface FONT_NAME;


    public CustomReqularTextView(Context context) {
        super(context);
        if(FONT_NAME == null) FONT_NAME = Typeface.createFromAsset(context.getAssets(), "fonts/OpenSans-Regular_0.ttf");
        this.setTypeface(FONT_NAME);
    }
    public CustomReqularTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
        if(FONT_NAME == null) FONT_NAME = Typeface.createFromAsset(context.getAssets(), "fonts/OpenSans-Regular_0.ttf");
        this.setTypeface(FONT_NAME);
    }
    public CustomReqularTextView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        if(FONT_NAME == null) FONT_NAME = Typeface.createFromAsset(context.getAssets(), "fonts/OpenSans-Regular_0.ttf");
        this.setTypeface(FONT_NAME);
    }
}

Then We have to use like

<com.crm.Common.CustomBoldTextView    android:layout_width="wrap_content"    android:layout_height="wrap_content"    android:id="@+id/compid"    android:text="@string/compname"    android:layout_gravity="center_horizontal"/>

Get all phone contacts using android

hi guys i going to explain get mobile contacts from phone
 it's very simple

Get Name

cur.getString(cur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));

Get Phone number 

cur.getString(cur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));

Get Phone email


cur.getString(cur.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));

First We have to add below  permission in Adroidmanifast.xml

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

activity_main.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"    android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin"    android:paddingRight="@dimen/activity_horizontal_margin"    android:paddingTop="@dimen/activity_vertical_margin"    android:paddingBottom="@dimen/activity_vertical_margin"    tools:context="com.readcontact.Contactlist"    android:orientation="vertical">
