我正在为 android 创建一个联系人应用程序，我已经成功创建了联系人的列表视图，并且还检索了联系人图像（对于那些有图像的联系人），并且没有任何图像的联系人显示没有任何图像任何图像。我需要使用默认联系人剪影图像显示没有任何图像的联系人。这是代码

private void populateContactList() {
        // TODO Auto-generated method stub
        // Build adapter with contact entries
        Cursor cursor = getContacts();
        String[] fields = new String[] { ContactsContract.Data.DISPLAY_NAME,
                ContactsContract.Data.PHOTO_THUMBNAIL_URI };
        adapter = new SimpleCursorAdapter(this, R.layout.contactentrylayout,
                cursor, fields, new int[] { R.id.contactEntryText,
                        R.id.contactimageentry });
        mContactList.setAdapter(adapter);
    }

    @SuppressWarnings("deprecation")
    private Cursor getContacts() {
        // TODO Auto-generated method stub
        // Run query
        Uri uri = ContactsContract.Contacts.CONTENT_URI;
        String[] projection = new String[] { ContactsContract.Contacts._ID,
                ContactsContract.Contacts.DISPLAY_NAME,
                ContactsContract.Data.PHOTO_THUMBNAIL_URI };
        // String selection = ContactsContract.Contacts.IN_VISIBLE_GROUP +
        // " = '"
        // + (mShowInvisible ? "0" : "1") + "'";
        String selection = ContactsContract.Contacts.DISPLAY_NAME
                + " LIKE ? OR "
                + ContactsContract.Contacts.DISPLAY_NAME_ALTERNATIVE
                + " LIKE ?";
        String[] selectionArgs = { etquery.getText().toString() + "%",
                etquery.getText().toString() + "%" };
        String sortOrder = ContactsContract.Contacts.DISPLAY_NAME
                + " COLLATE LOCALIZED ASC";

        return managedQuery(uri, projection, selection, selectionArgs,
                sortOrder);
    }
