将联系人图像加载到位图中

我用来从电话号码获取联系图像缩略图的Uri的function。 :

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); } 

哪个将以以下forms返回Uri:

 content://com.android.contacts/contacts/799/photo 

现在,如果我使用setImageUri(Uri)函数在ImageView中使用此Uri,它可以工作。

但加载位图是一个问题。 我正在使用的function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:

请帮忙!

我不认为你应该将照片的uri传递给openContactphotoinputstream。 你只需要传递联系人本身的uri来获取位图。

  Uri uri = ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, id); InputStream stream = ContactsContract.Contacts.openContactPhotoInputStream( mContext.getContentResolver(), uri); 

或者,如果您打算通过联系人照片uri,那么您可以使用

 public static Bitmap getContactBitmapFromURI(Context context, Uri uri) { InputStream input = context.getContentResolver().openInputStream(uri) if (input == null) { return null; } return BitmapFactory.decodeStream(input); }
