Android gets the contact avatar instance code based on the phone number

In the daily use of Android mobile phone, it is a common problem to get the contact avatar according to the phone number. This article is an example of Android's implementation code for getting contact personas based on phone Numbers. To share with you for your reference. The specific methods are as follows:

First, data such as contacts in Android can be accessed through ContentProvider. Common Uri are:

Contact information Uri: content: / / com android. contacts/contacts
Contact telephone Uri: content: / / com android. contacts/data/phones
Contact email Uri: content: / / com android. contacts/data/emails

It also provides the function to obtain the data of data table according to the telephone number by data/phones/filter/ number, and returns 1 data set. Then get the contact's contact_id through the data set, open InputStream according to contact_id, and finally get the contact's avatar with ES43en.decodeStream ().

The specific function code is as follows:

//  Get the contact profile picture based on the number 
public static void get_people_image(String x_number){  
 
  //  To obtain Uri
  Uri uriNumber2Contacts = Uri.parse("content://com.android.contacts/"
      + "data/phones/filter/" + x_number); 
  //  The query Uri , returns the data set 
  Cursor cursorCantacts = context.getContentResolver().query(
      uriNumber2Contacts, 
      null, 
      null,            
      null, 
      null);
  //  If the contact exists 
  if (cursorCantacts.getCount() > 0) { 
    //  Move to the first 1 The data 
    　　　　　　cursorCantacts.moveToFirst();
    　　　　　　//  Access to the contact contact_id
    　　　　　　 Long contactID = cursorCantacts.getLong(cursorCantacts.getColumnIndex("contact_id"));
    　　　　　　//  To obtain contact_id the Uri
    　　　　　　 Uri uri = ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, contactID);
    　　　　　　//  Open the profile picture InputStream
    　　　　　　InputStream input = ContactsContract.Contacts.openContactPhotoInputStream(context.getContentResolver(), uri); 
    　　　　　　//  from InputStream To obtain bitmap
    　　　　　　bmp_head = BitmapFactory.decodeStream(input);
