我有一个ListView
应该成为一个菜单,每行有两个可绘制对象和两个文本视图。
活动代码:
ArrayList<MenuItem> itemArray = new ArrayList<MenuItem>();
itemArray.add(new MenuItem("Headertexxt", "subbtexdt"));
itemArray.add(new MenuItem("asf", "asf"));
ListView listView = (ListView) findViewById(R.id.listViewCM);
String[] array = getResources().getStringArray(R.array.buttonsCM);
int[] images = new int[] { R.drawable.btn_car, R.drawable.btn_star, R.drawable.btn_bag};
listView.setAdapter(new HomeScreenButtonsAdapterSubtext(this, R.layout.row,
itemArray, images, R.drawable.list_arrow));
Utils.setListViewHeightBasedOnChildren(listView);
listView.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
switch (position) {
case 0:
findViewById(R.id.buttonCreditCompilation).performClick();
break;
case 1:
findViewById(R.id.buttonYourCredits).performClick();
break;
}
}
});
适配器代码:
public class HomeScreenButtonsAdapterSubtext extends ArrayAdapter<MenuItem> {
private Drawable[] drawables;
private Drawable arrowDrawable;
private ArrayList<MenuItem> items;
public HomeScreenButtonsAdapterSubtext(Context context, int resourceId,
ArrayList<MenuItem> items, int[] images, int arrowImage) {
super(context, resourceId, items);
this.items = items;
Resources resources = context.getResources();
if (images != null) {
drawables = new Drawable[images.length];
int i = 0;
for (int id : images) {
Drawable drawable = resources.getDrawable(id);
drawable.setBounds(0, 0, drawable.getIntrinsicWidth(),
drawable.getIntrinsicHeight());
drawables[i++] = drawable;
}
}
arrowDrawable = resources.getDrawable(arrowImage);
arrowDrawable.setBounds(0, 0, arrowDrawable.getIntrinsicWidth(),
arrowDrawable.getIntrinsicHeight());
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = super.getView(position, convertView, parent);
if (v instanceof TextView) {
Drawable dr = drawables != null ? drawables[position %
drawables.length] : null;
((TextView) v).setCompoundDrawables(dr, null, arrowDrawable, null);
Utils.setFont((TextView) v);
}
// View v = convertView;
if (v == null) {
LayoutInflater vi = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate(R.layout.row, null);
}
MenuItem station = items.get(position);
if (station != null) {
TextView tt = (TextView) v.findViewById(R.id.headerText);
TextView bt = (TextView) v.findViewById(R.id.subText);
if (tt != null) {
tt.setText(station.getHeaderText());
}
if (bt != null) {
bt.setText(station.getSubText());
}
}
return v;
}
我现在遇到的问题是我无法设置listview height
基于孩子。我在这里尝试这样做:Utils.setListViewHeightBasedOnChildren(listView);
但收到错误:arrayadapter requires the resource id to be a textview
在这一行。有谁知道这个的解决方案?
我可以使用其他方法来设置ListView
高度吗?
谢谢
