문제
XML에서 다음 레이아웃이 정의되어 있습니다.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_height="wrap_content" android:layout_width="wrap_content" android:id="@+id/streamRelativeLayout">
<ListView android:layout_height="fill_parent" android:layout_width="fill_parent" android:id="@+id/streamListView"></ListView>
<ProgressBar android:layout_centerInParent="true" android:layout_height="wrap_content" android:id="@+id/streamProgressBar" android:layout_width="wrap_content"></ProgressBar>
</RelativeLayout>
.
LayoutInflater를 사용하여 ListView 및 ProgressBar를 잡고 코드에 할당하고 코드에 할당 할 수 있습니까?
해결책
이 방법으로 :
View v = getLayoutInflater().inflate(R.layout.YOUR_LAYOUT_ID, null);
ListView listview = (ListView) v.findViewById(R.id.streamListView);
ProgressBar progress = (ProgressBar) v.findViewById(R.id.streamProgressBar);
. 다른 팁
You just need the activity reference and call :
RelativeLayout relativeLayout = (RelativeLayout)activity.getLayoutInflater().inflate(R.layout.your_layout, null);
Then you can grab the two view using their ids
relativeLayout.findViewById(R.id.anId);
try this
RelativeLayout myLayout = (RelativeLayout)getLayoutInflater().inflate(
R.layout.you_xml_id, null);
ListView list = (ListView)myLayout.findViewById(R.id.streamListView);
ProgressBar bar = (ProgressBar)myLayout.findViewById(R.id.streamProgressBar);
private LayoutInflater mInflater;
View convertView;
mInflater = LayoutInflater.from(context);
convertView = mInflater.inflate(R.xml.yourxmlname, null);
now you can access the items by
convertView.findViewById
or if you hav lots of Instances, you may define a viewholder
static class CalViewHolder {
ListView con_list;
Progressbar con_progress;
}
holder = new CalViewHolder();
convertView.setTag(holder);
