我有问题设计明智。我正在寻找在listView中的一行内hortizontally显示两张图片。像这样：Listview中的布局问题
TextView
ImageView
ImageView
我期待着看我是否可以只使用一个xml，或者我必须考虑完全使用不同的视图。我有Listview和通过baseadapter的自定义行xml。详见
代码public class MyCustomBaseAdapter extends BaseAdapter {
private Integer[] imgid = {
R.drawable.up2,
R.drawable.up3,
R.drawable.up4,
R.drawable.up5,
R.drawable.up6,
R.drawable.up7,
R.drawable.up8,
R.drawable.up9,
R.drawable.down2,
R.drawable.down3,
R.drawable.down4,
R.drawable.down5,
R.drawable.down6,
R.drawable.down7,
R.drawable.down8,
R.drawable.down9 };
private static ArrayList<DisplayResults> searchArrayList;
private LayoutInflater mInflater;
public MyCustomBaseAdapter(Context context, List<DisplayResults> list) {
searchArrayList = (ArrayList<DisplayResults>) list;
mInflater = LayoutInflater.from(context);
}
public int getCount() {
return searchArrayList.size();
}
public Object getItem(int position) {
return searchArrayList.get(position);
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
convertView = mInflater.inflate(R.layout.list_row, null);
holder = new ViewHolder();
//holder.txtName = (TextView) `
convertView.findViewById(R.id.ServiceName);
holder.imgPhoto = (ImageView) convertView.findViewById(R.id.Up);
//holder.imgPhoto2= (ImageView) convertView.findViewById(R.id.Down);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
//holder.txtName.setText(searchArrayList.get(position).getName());
holder.imgPhoto.setImageResource(imgid[searchArrayList.get(position).getImageNumber()]);
System.out.println(searchArrayList.get(position).getImageNumber());
//holder.imgPhoto2.setImageResource(imgid[searchArrayList.get(position).getImageNumber2()]);
return convertView;
}
static class ViewHolder {
TextView txtName;
ImageView imgPhoto;
//ImageView imgPhoto2;
}
}
public class satDataFrag extends Fragment {
Data datas;
ListView listView;
LayoutInflater inflaterT;
public satDataFrag(Data data)
{
this.datas=data;
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
View view = inflater.inflate(R.layout.sat, container, false);
inflaterT = inflater;
listView = (ListView) view.findViewById(R.id.listSat);
//ImageView imgView;
//imgView = (ImageView) view.findViewById(R.id.icon);
List<DisplayResults> List = new ArrayList<DisplayResults>();
DisplayResults temp= new DisplayResults();
for(int i=0; i<datas.features.size(); i++)
{
if(datas.features.get(i).attributes.ServiceTyp.equalsIgnoreCase("Satellite"))
{
temp.setName(datas.features.get(i).attributes.dbANAME);
temp.setImageNumber(upKey(datas.features.get(i).attributes.maxADUP));
temp.setImageNumber2(downKey(datas.features.get(i).attributes.maxADDOWN));
List.add(temp);
}
}
//ArrayAdapter<Integer> adapter = new ArrayAdapter<Integer>(getActivity(),
// R.layout.list_row, List);
listView.setAdapter(new MyCustomBaseAdapter(getActivity(), List));
return view;
}
public Integer upKey (String max)
{
if(max.equalsIgnoreCase("2"))
{
return 0;
}
else if(max.equalsIgnoreCase("3"))
{
return 1;
}
else if(max.equalsIgnoreCase("4"))
{
return 2;
}
else if(max.equalsIgnoreCase("5"))
{
return 3;
}
else if(max.equalsIgnoreCase("6"))
{
return 4;
}
else if(max.equalsIgnoreCase("7"))
{
return 5;
}
else if(max.equalsIgnoreCase("8"))
{
return 6;
}
else if(max.equalsIgnoreCase("9"))
{
return 7;
}
else
{
return 7;
}
}
public Integer downKey (String max)
{
if(max.equalsIgnoreCase("2"))
{
return 8;
}
else if(max.equalsIgnoreCase("3"))
{
return 9;
}
else if(max.equalsIgnoreCase("4"))
{
return 10;
}

{
return 11;

{
return 12;
}
else if(max.equalsIgnoreCase("7"))
{
return 13;
}

{
return 14;
}
else if(max.equalsIgnoreCase("9"))
{
return 15;
}
else
{
return 7;
}
}
}
custom_row.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/ServiceName"
android:text=""/>
<ImageView
android:id="@+id/Up"
android:layout_gravity="left"
android:layout_width="match_parent"
android:layout_height="wrap_content"
/>
<ImageView
android:id="@+id/Down"
android:layout_gravity="left"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
所以我的问题是：是否有办法来显示两个图像和一个ListView内一行文字？
什么是错误？ – Tushar 2013-04-08 03:07:14
不是一个错误，而是更多的问题。代码运行时。我只看到文字。当我从XML删除文本条目我可以看到第一张图片，当我删除第一张图片等...我需要一个足够大的行来查看所有它 – vaultzero 2013-04-08 03:57:12
你能否详细说明你的问题。 – Harshid 2013-04-08 04:52:29
