问题描述
我正在尝试将android actionbar微调器自定义为类似于google电流应用程序的东西。基本上，只有'副标题'应该反映我从微调器中选择的标题保持不变。我知道需要创建一个自定义微调框，我必须覆盖 getView（）和 getDropDownView（）方法。但是我在这里非常困惑如何正确地覆盖这些方法。有些人可以向我推动正确的方向。我希望我清楚我的问题。
I am trying to customise the android actionbar spinner to something that like the google currents application. Basically, only the 'subtitle' should reflect what i choose from the spinner while the 'title' remains the same. I understand that a custom spinner needs to be created and I have to override the getView() and getDropDownView() method. But I am very confused here on how to override these methods properly. Can some please nudge me in the right direction. I hope I made my question clear.
以下是我的代码。
public class CustomSpinnerAdapter extends BaseAdapter {
private LayoutInflater inflater;
private final Context context;
private final String[] dropDown;
private final String mainText;
private final String subText;
public CustomSpinnerAdapter(Context context,
String mainText, String subText,String[] dropDown) {
inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
this.mainText=mainText;
this.subText=subText;
this.context = context;
this.dropDown=dropDown;
}
@Override
public int getCount() {
// TODO Auto-generated method stub
return 0;
}
@Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return null;
}
@Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return 0;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
View actionBarView = inflater.inflate(R.layout.custom_spinner, null);
TextView textView = (TextView) actionBarView
.findViewById(R.id.custom_spinner_textview);
textView.setText(mainText);
return actionBarView;
}
@Override
public View getDropDownView(int position, View convertView, ViewGroup parent) {
View dropDownView = inflater.inflate(R.layout.custom_spinner, null);
TextView dropDownTextView = (TextView) dropDownView
.findViewById(R.id.custom_spinner_dropdown_textview);
dropDownTextView.setText(dropDown[position]);
return dropDownView;
}
}
推荐答案
我解决了这个问题。
我的适配器类列表：
public class AdapterBaseMaps extends BaseAdapter {
Context context;
int layoutResourceId;
ArrayList<ObjectLayers> data;
LayoutInflater inflater;
public AdapterBaseMaps(Context context, int textViewResourceId,
ArrayList<ObjectLayers> data) {
// super(a, textViewResourceId, data);
this.data = data;
inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
this.context = context;
this.layoutResourceId = textViewResourceId;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View actionBarView = inflater.inflate(R.layout.ab_main_view, null);
TextView title = (TextView) actionBarView
.findViewById(R.id.ab_basemaps_title);
TextView subtitle = (TextView) actionBarView
.findViewById(R.id.ab_basemaps_subtitle);
title.setText(context.getResources()
.getString(R.string.label_cartravel));
subtitle.setText(data.get(position).getLayerName());
return actionBarView;
}
@Override
public View getDropDownView(int position, View convertView, ViewGroup parent) {
View actionBarDropDownView = inflater.inflate(
R.layout.ab_dropdown_view, null);
TextView dropDownTitle = (TextView) actionBarDropDownView
.findViewById(R.id.ab_basemaps_dropdown_title);
dropDownTitle.setText(data.get(position).getLayerName());
return actionBarDropDownView;
}
@Override
public int getCount() {
// TODO Auto-generated method stub
return data.size();
}
@Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return null;
}
@Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return 0;
}
}
