我在RouteView
中使用自定义视图(ArrayAdapter
)并尝试在此处使用自定义视图,因此我可以对该对象执行某些逻辑,但由于某种原因,它似乎隐形!我可以与它互动,但没有任何东西可见。
这是我的RouteView课程:
public class RouteView extends RelativeLayout {
public RouteView(Context context){
super(context);
init();
}
private void init(){
inflate(getContext(), R.layout.route_item, this);
}
public void setFrom(String fromText){
TextView from = (TextView) findViewById(R.id.from);
from.setText(fromText);
}
public void setTo(String toText){
TextView to = (TextView) findViewById(R.id.to);
to.setText(toText);
}
public RouteView(Context context, AttributeSet attrs) {
super(context, attrs);
}
@Override
protected void onLayout(boolean b, int i, int i1, int i2, int i3) {
}
以下是我如何构建它:
private class RoutesAdapter extends ArrayAdapter{
public RoutesAdapter(Context context, int resource, ArrayList<Route> objects) {
super(context, resource, objects);
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
RouteView v;
if(convertView == null){
v = new RouteView(getContext());
} else {
v = (RouteView) convertView;
}
Route route = (Route) getItem(position);
v.setFrom(route.getFrom());
v.setTo(route.getTo());
return v;
}
}
我的XML根元素是<merge>
元素RelativeLayout
。有谁知道我在这里做错了什么?
谢谢!
答案 0 :(得分:1)
是的,@ kingfisher-phuoc说你的:
@Override
protected void onLayout(boolean b, int i, int i1, int i2, int i3) {
}
尝试调用super:
@Override
protected void onLayout(boolean b, int i, int i1, int i2, int i3) {
super.onLayout(b, i, i1, i2, i3);
... //your code
}
或者不要覆盖此方法
