Android gets contact Avatar instance code based on phone number _android

In the daily use of the Android phone, the phone number to get a contact avatar, is often encountered problems. This article is an example of how Android is getting contact with a phone number to get a head image of the implementation code. Share for everyone to use for reference. The specific methods are as follows:

First, through ContentProvider, you can access data such as contacts in Android. The common URIs are:

Contact Information uri:content://com.android.contacts/contacts
Contact Phone Uri:content://com.android.contacts/data/phones
Contact Mail Uri:content://com.android.contacts/data/emails

It also provides the ability to obtain data from a data table based on a phone number by: data/phones/filter/number, which returns a DataSet. Then through the dataset to get the contact's contact_id, according to contact_id open avatar picture InputStream, and finally with Bitmapfactory.decodestream () Get contact person's head.

The specific function code is as follows:

According to the number get contact head like public static void Get_people_image (String x_number) {//get URI uri urinumber2contacts = uri.parse ( 
  "content://com.android.contacts/" + "data/phones/filter/" + x_number); 
      The query URI, which returns the dataset Cursor Cursorcantacts = Context.getcontentresolver (). query (urinumber2contacts, NULL,
  NULL, NULL, NULL);
    　　　　　　If the contact exists if (Cursorcantacts.getcount () > 0) {//move to the first Data Cursorcantacts.movetofirst ();
    　　　　　　Get the contact's contact_id Long ContactID = Cursorcantacts.getlong (Cursorcantacts.getcolumnindex ("contact_id")); Gets the URI uri of the contact_id = Contenturis.withappendedid (ContactsContract.Contacts.CONTENT_URI, Contacti
    　　　　　　D); Open the Avatar picture inputstream inputstream input = ContactsContract.Contacts.openContactPhotoInputStream (context.getconte 
    　　　　　　Ntresolver (), URI);   
Obtain Bitmap Bmp_head = Bitmapfactory.decodestream (input) from InputStream;
