我有一個列表適配器, ,它完美..但後來我的ListView不能爲主題的..Android ClassCastException - 從LayoutLabout從LinearLayout到AbsListView
public View getView(int position, View convertView, ViewGroup parent) {
//System.gc();
TextView tv;
LayoutInflater inflater = getLayoutInflater();
View row = View.inflate(mContext,R.layout.item,null); //.inflate(R.layout.item, parent, false); doesnt work either..
String id = null;
if (convertView == null) {
tv = (TextView) row.findViewById(R.id.TextView01);;
} else
tv = (TextView) convertView;
[..]
在logcat
我得到這個..

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="wrap_content"
android:gravity="left|center"

android:paddingTop="15px"

android:layout_height="wrap_content"
android:textSize="40px"
