這篇文章主要介紹了Android獲取聯(lián)系人頭像的方法,結(jié)合實(shí)例形式分析了Android調(diào)用聯(lián)系人頭像的相關(guān)操作技巧,涉及Bitmap對(duì)象及ImageView的使用方法,需要的朋友可以參考下

本文實(shí)例講述了Android獲取聯(lián)系人頭像的方法。分享給大家供大家參考，具體如下：

public byte[] getPhoto(String people_id) {
String photo_id = null;
String selection1 = ContactsContract.Contacts._ID + " = " + people_id;
Cursor cur1 = getContentResolver().query(
ContactsContract.Contacts.CONTENT_URI, null, selection1, null, null);
if (cur1.getCount() > 0)
{
cur1.moveToFirst();
photo_id = cur1.getString(cur1.getColumnIndex(ContactsContract.Contacts.PHOTO_ID));
//System.out.println("photo_id:" + photo_id);
}
String[] projection = new String[]
{
ContactsContract.Data.DATA15
};
String selection = ContactsContract.Data._ID + " = " + photo_id;
Cursor cur = getContentResolver().query(
ContactsContract.Data.CONTENT_URI, projection, selection, null, null);
cur.moveToFirst();
byte[] contactIcon = cur.getBlob(0);
System.out.println("conTactIcon:" + contactIcon);
if (contactIcon == null) {
return null;
} else {
return contactIcon;
}
}

以下代碼將字節(jié)數(shù)組轉(zhuǎn)化成Bitmap對(duì)象，然后再I(mǎi)mageView中顯示出來(lái)

private ImageView image;
byte[] photo = getPhoto(contactId);
Bitmap map = BitmapFactory.decodeByteArray(photo, 0,photo.length);
image.setImageBitmap(map);

通過(guò)代碼設(shè)置Android聯(lián)系人的頭像：

private final static boolean OldSDK = (System.getSDKVersionNumber()< 5 )? true : false;
public static void setPersonPhotoBytes(Context context,byte[] b, long persionID, boolean Sync)
{
if (OldSDK){
Uri myPerson = ContentUris.withAppendedId(People.CONTENT_URI, persionID);
People.setPhotoData(context.getContentResolver(), myPerson, b);
if (! Sync){
ContentValues values = new ContentValues();
values.put("_sync_dirty", 0);
context.getContentResolver().update(myPerson, values, null, null);
}
}
else
setContactPhoto5(context.getContentResolver(), b, persionID, Sync);
}
private static void setContactPhoto5(ContentResolver c, byte[] bytes,long personId, boolean Sync)
{
ContentValues values = new ContentValues();
Uri u = Uri.parse("content://com.android.contacts/data");
int photoRow = -1;
String where ="raw_contact_id = " + personId + " AND mimetype ='vnd.android.cursor.item/photo'";
Cursor cursor = c.query(u, null, where, null, null);
int idIdx = cursor.getColumnIndexOrThrow("_id");
if (cursor.moveToFirst()) {
photoRow = cursor.getInt(idIdx);
}
cursor.close();
values.put("raw_contact_id", personId);
values.put("is_super_primary", 1);
values.put("data15", bytes);
values.put("mimetype","vnd.android.cursor.item/photo");
if (photoRow >= 0) {
c.update(u, values, " _id= " + photoRow, null);
} else {
c.insert(u, values);
}
if (! Sync){
u = Uri.withAppendedPath(Uri.parse("content://com.android.contacts/raw_contacts"),
String.valueOf(personId));
values = new ContentValues();
values.put("dirty", 0);
c.update(u, values, null, null);
}
}
