我要动态地添加意见，这一部分：
I want to add views dynamicly to this part:
<!-- Latest Comments -->
<LinearLayout
android:id="@+id/comment_items"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
</LinearLayout>
这是怎么吹：
private void inflateComments() {
LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
LinearLayout container = (LinearLayout) findViewById(R.id.comment_items);
for (int i = 0; i < commentItems.size(); i++) {
View commentView = inflater.inflate(R.layout.comment_item, null);
TextView title = (TextView) commentView.findViewById(R.id.comment_title);
TextView text = (TextView) commentView.findViewById(R.id.comment_text);
TextView date = (TextView) commentView.findViewById(R.id.comment_post_date);
title.setText(commentItems.get(i).getAuthorName() + commentItems.get(i).getAuthorName());
text.setText(commentItems.get(i).getComment());
date.setText(commentItems.get(i).getPostDate());
container.addView(commentView);
}
}
不幸的是它没有任何膨胀意见纳入这个LinearLayout中。布局是空白一片。任何想法，为什么它不工作？自定义布局ID是匹配的。
Unfortunately it does not inflate any views into this LinearLayout. Layout is blank inside. Any ideas why it does not work? Custom layout ids are matching.
推荐答案
尝试设置你的容器的高度，以 WRAP_CONTENT insted的match_parent
Try setting height of yours container to wrap_content insted of "match_parent"
