我有一个ListView,我希望其中的前两个条目与其余条目的显示方式不同。没什么好看的,我希望它们都只是文本视图。但前两个条目需要具有不同的尺寸和重量。我尝试修改ArrayAdapter类,如下所示:
private class BusStopAdapter<T> extends ArrayAdapter<T>{
public BusStopAdapter(
Context context, int textViewResourceId,
List<T> objects)
{
super(context, textViewResourceId, objects);
}
public View getView(int position, View convertView,
ViewGroup parent)
{
TextView toReturn =
(TextView)super.getView(position, convertView, parent);
if(position == 0){
toReturn.setTextSize(12);
toReturn.setText("Previous Bus: " + toReturn.getText());
toReturn.setPadding(0,0,0,0);
}
else if(position == 1){
toReturn.setTextSize(20);
toReturn.setPadding(
toReturn.getPaddingLeft(),
0,
toReturn.getPaddingRight(),
0
);
toReturn.setText("Next Bus: " + toReturn.getText());
toReturn.setGravity(Gravity.CENTER_HORIZONTAL|Gravity.TOP);
}
return toReturn;
}
}
但是这无意中导致其他一些文本视图呈现出这些特殊属性。我认为这是因为原因文本视图在AbsListAdapter类中被“回收”。

试试这样:
if(position == 0){
toReturn.setTextSize(12);
toReturn.setText("Previous Bus: " + toReturn.getText());
toReturn.setPadding(0,0,0,0);
}
else if(position == 1){
toReturn.setTextSize(20);
toReturn.setPadding(
toReturn.getPaddingLeft(),
0,
toReturn.getPaddingRight(),
0
);
else
style it normally or whatever you want.........
