我的android函数返回URI
,如下所示:
content://com.android.contacts/contacts/@some number@
当我知道URI
时,如何获取此联系人的照片?
修改
为什么以下代码不起作用:
Uri test = Uri.parse("content://com.android.contacts/contacts/227");
row.setImageViewUri(android.R.id.icon, test);
答案 0 :(得分:2)
你应该使用这种方法:
public Uri getPhotoUri() {
try {
Cursor cur = this.ctx.getContentResolver().query(
ContactsContract.Data.CONTENT_URI,
null,
ContactsContract.Data.CONTACT_ID + "=" + this.getId() + " AND "
+ ContactsContract.Data.MIMETYPE + "='"
+ ContactsContract.CommonDataKinds.Photo.CONTENT_ITEM_TYPE + "'", null,
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(getId()));
return Uri.withAppendedPath(person, ContactsContract.Contacts.Photo.CONTENT_DIRECTORY);
}
用法是:
Uri u = objItem.getPhotoUri();
if (u != null) {
mPhotoView.setImageURI(u);
} else {
mPhotoView.setImageResource(R.drawable.ic_contact_picture_2);
}
