我有一个列表视图,我正在尝试为它设置标题,使其看起来像一个表头。这是我的列表视图行的XML文件:
PS:我删除了一些代码来缩短问题
<?xml version="1.0" encoding="utf-8"?>
<TextView
android:id="@+id/txtDisplayDate"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1" />
<TextView
android:id="@+id/txtDisplayCat"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1" />
</LinearLayout>
我的标题列表视图的XML文件:
<?xml version="1.0" encoding="utf-8"?>
<TextView
android:id="@+id/txtDisplayDate"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="Date" />
<TextView
android:id="@+id/txtDisplayCat"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="Category" />
我填充列表视图的类:
private class ListAdapter extends BaseAdapter {
LayoutInflater inflater;
ViewHolder viewHolder;
public ListAdapter(Context context) {
// TODO Auto-generated constructor stub
inflater = LayoutInflater.from(context);
LinearLayout listHeaderView = (LinearLayout)inflater.inflate(
R.layout.trans_header_layout, null);
listview.addHeaderView(listHeaderView);
}
@Override
public int getCount() {
// TODO Auto-generated method stub
return _translist.size();
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
if (convertView == null) {
convertView = inflater.inflate(R.layout.trans_listview_row,
null);
viewHolder = new ViewHolder();
viewHolder.txt_ddate = (TextView) convertView
.findViewById(R.id.txtDisplayDate);
viewHolder.txt_dcat = (TextView) convertView
.findViewById(R.id.txtDisplayCat);
} else {
viewHolder = (ViewHolder) convertView.getTag();
}
viewHolder.txt_ddate.setText(_translist.get(position).getDate()
.trim());
viewHolder.txt_dcat.setText(_translist.get(position)
.getCategory().trim());
return convertView;
}
}
但是,通过使用这些代码,这是我得到的输出:
标题与其下方的列不匹配。我想知道是否有任何替代方法可以将标题添加到列表视图中,使其看起来像一个表头。
提前致谢。
修改
listview所在的我的transaction_rec.XML:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<LinearLayout
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:orientation="vertical" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Date" />
<TextView
android:id="@+id/txtDisplayDate"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
<LinearLayout
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:orientation="vertical" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Category" />
<TextView
android:id="@+id/txtDisplayCat"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
</LinearLayout>
<ListView
android:id="@+id/listview"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
</ListView>
</LinearLayout>
我的transactionRec.java:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.transaction_rec);
context = this;
listview = (ListView) findViewById(R.id.listview);
//Code to get data from database
}
private class ListAdapter extends BaseAdapter {
LayoutInflater inflater;
ViewHolder viewHolder;
public ListAdapter(Context context) {
// TODO Auto-generated constructor stub
inflater = LayoutInflater.from(context);
}
@Override
public int getCount() {
// TODO Auto-generated method stub
return _translist.size();
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
if (convertView == null) {
convertView = inflater.inflate(R.layout.transaction_rec,
null);
viewHolder = new ViewHolder();
viewHolder.txt_ddate = (TextView) convertView
.findViewById(R.id.txtDisplayDate);
viewHolder.txt_dcat = (TextView) convertView
.findViewById(R.id.txtDisplayCat);
} else {
viewHolder = (ViewHolder) convertView.getTag();
}
viewHolder.txt_ddate.setText(_translist.get(position).getDate()
.trim());
viewHolder.txt_dcat.setText(_translist.get(position)
.getCategory().trim());
return convertView;
}
}
}
我现在得到的输出:
答案 0 :(得分:0)
试试这个......
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
包含所有文字视图。
