我用来从电话号码中获取联系人图像缩略图的 Uri 的功能。:
public static Uri getPhotoURIFromAddress(Context activity, String address) {
String contactId = getContactIdFromAddress(activity, address);
ContentResolver contentResolver = activity.getContentResolver();
try {
Cursor cursor = contentResolver
.query(ContactsContract.Data.CONTENT_URI,
null,
ContactsContract.Data.CONTACT_ID
+ "="
+ contactId
+ " AND "
+ ContactsContract.Data.MIMETYPE
+ "='"
+ ContactsContract.CommonDataKinds.Photo.CONTENT_ITEM_TYPE
+ "'", null, null);
if (cursor != null) {
if (!cursor.moveToFirst()) {
return null; // no photo
}
} else {
return null; // error in cursor process
}
cursor.close();
} catch (Exception e) {
e.printStackTrace();
return null;
}
Uri person = ContentUris.withAppendedId(
ContactsContract.Contacts.CONTENT_URI, Long.valueOf(contactId));
return Uri.withAppendedPath(person,
ContactsContract.Contacts.Photo.CONTENT_DIRECTORY);
}
它将以以下形式返回 Uri:
content://com.android.contacts/contacts/799/photo
现在,如果我在带有 setImageUri(Uri) 函数的 ImageView 中使用这个 Uri,它就可以工作。
但是加载位图是一个问题。我正在使用的功能是:
public static Bitmap getContactBitmapFromURI(Context context, Uri uri) {
InputStream input = ContactsContract.Contacts
.openContactPhotoInputStream(context.getContentResolver(), uri);
if (input == null) {
return null;
}
return BitmapFactory.decodeStream(input);
}
总是崩溃。LogCat 是:
