我有一个listview适配器,我在newView方法中尝试以下操作：
@Override
public View newView(Context context,Cursor cursor,ViewGroup parent) {
final LayoutInflater inflater = LayoutInflater.from(context);
View v = inflater.inflate(layout,parent,false);
long contactId = Long.valueOf(cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID)));
String contactName = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
boolean hasPhone = Boolean.parseBoolean(cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER)));
String thumbnailUri = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.PHOTO_THUMBNAIL_URI));
TextView name_text = (TextView) v.findViewById(R.id.name_entry);
if (name_text != null) {
name_text.setText(contactName);
}
name_text.setTag(new Contact(contactId,hasPhone));
ImageView thumbnail = (ImageView) v.findViewById(R.id.thumbnail);
if (thumbnailUri != null) {
thumbnail.setImageURI(Uri.parse(thumbnailUri));
} else {
thumbnail.setImageResource(R.drawable.ic_launcher);
}
return v;
}
但是当我尝试解析存储在thumbnailUri中的Uri时,我收到以下错误：
08-09 01:58:38.619: I/System.out(1471): resolveUri Failed on bad bitmap uri: content://com.android.contacts/contacts/1/photo
我这样做错了吗？任何帮助将不胜感激！
解决方法
private Uri getPhotoUriFromID(String id) {
try {
Cursor cur = getContentResolver()
.query(ContactsContract.Data.CONTENT_URI,null,ContactsContract.Data.CONTACT_ID
+ "="
+ id
+ " AND "
+ ContactsContract.Data.MIMETYPE
+ "='"
+ ContactsContract.CommonDataKinds.Photo.CONTENT_ITEM_TYPE
+ "'",null);
if (cur != null) {
if (!cur.moveToFirst()) {
return null; // no photo
}
} else {
return null; // error in cursor process
}
} catch (Exception e) {
e.printStackTrace();
return null;
}
Uri person = ContentUris.withAppendedId(
ContactsContract.Contacts.CONTENT_URI,Long.parseLong(id));
return Uri.withAppendedPath(person,ContactsContract.Contacts.Photo.CONTENT_DIRECTORY);
}
这是您需要传递联系人ID的功能,您将获得可以在图像视图中轻松设置的图像的URI.
使用此功能的响应uri,如imageView.setImageURI(uri)
希望它能为您的代码工作.
