自定义微调适配器 [英] Custom Spinner Adapter

问题描述

我想自定义字体应用到我的微调。我发现的唯一方法是创建一个自定义的适配器。这是我的code

 私有类CustomAdapter扩展ArrayAdapter {

    私人上下文的背景下;
    私人列表＆LT; CharSequence的＆GT; ITEMLIST;
    公共CustomAdapter（上下文的背景下，INT textViewResourceId，名单，其中，为CharSequence＆GT; ITEMLIST）{

        超（背景下，textViewResourceId）;
        this.context =背景;
        this.itemList = ITEMLIST;
    }

    公众的TextView getView（INT位置，查看convertView，ViewGroup中父）{

        TextView的V =（TextView中）超
                .getView（位置，convertView，父母）;
        字样myTypeFace = Typeface.createFromAsset（context.getAssets（）
                字体/ gilsanslight.otf）;
        v.setTypeface（myTypeFace）;
        v.setText（itemList.get（位置））;
        返回伏;
    }

    公众的TextView getDropDownView（INT位置，查看convertView，
            ViewGroup中父）{

        TextView的V =（TextView中）超
                .getView（位置，convertView，父母）;
        字样myTypeFace = Typeface.createFromAsset（context.getAssets（）
                字体/ gilsanslight.otf）;
        v.setTypeface（myTypeFace）;
        v.setText（itemList.get（位置））;
        返回伏;
    }

}
 

然后使用

 名单，其中，为CharSequence＆GT; ITEMLIST =新的ArrayList＆LT; CharSequence的＆GT;（
            Arrays.asList（项目））;

    mySpinnerArrayAdapter =新CustomAdapter（背景下，android.R.layout.simple_spinner_item，ITEMLIST）;
    spinner.setAdapter（mySpinnerArrayAdapter）;
 

这样做了以后，我的适配器是空的。谁能帮帮我吗？项目包含国家的列表。

亲切的问候，

解决方案

尝试

 公开查看getView（INT位置，查看convertView，ViewGroup中父）{

    LayoutInflater充气= getLayoutInflater（）;
            查看排= inflater.inflate（yourRowlayout，父母，
                    假）;
       TextView中使=（TextView中）row.findViewById（R.id.Make）;
        字样myTypeFace = Typeface.createFromAsset（context.getAssets（）
                字体/ gilsanslight.otf）;
        v.setTypeface（myTypeFace）;
        v.setText（itemList.get（位置））;
        返回行;
    }


公共查看getDropDownView（INT位置，查看convertView，ViewGroup中父）{

        LayoutInflater充气= getLayoutInflater（）;
                查看排= inflater.inflate（yourRowlayout，父母，
                        假）;
           TextView中使=（TextView中）row.findViewById（R.id.Make）;
            字样myTypeFace = Typeface.createFromAsset（context.getAssets（）
                    字体/ gilsanslight.otf）;
            v.setTypeface（myTypeFace）;
            v.setText（itemList.get（位置））;
            返回行;
        }
 

I wanted to apply a custom font to my spinner. The only way i found out is that to create a custom adapter. Here is my code

    private class CustomAdapter extends ArrayAdapter {

    private Context context;
    private List<CharSequence> itemList;
    public CustomAdapter(Context context, int textViewResourceId,List<CharSequence> itemList) {

        super(context, textViewResourceId);
        this.context=context;
        this.itemList=itemList;
    }

    public TextView getView(int position, View convertView, ViewGroup parent) {

        TextView v = (TextView) super
                .getView(position, convertView, parent);
        Typeface myTypeFace = Typeface.createFromAsset(context.getAssets(),
                "fonts/gilsanslight.otf");
        v.setTypeface(myTypeFace);
        v.setText(itemList.get(position));
        return v;
    }

    public TextView getDropDownView(int position, View convertView,
            ViewGroup parent) {

        TextView v = (TextView) super
                .getView(position, convertView, parent);
        Typeface myTypeFace = Typeface.createFromAsset(context.getAssets(),
                "fonts/gilsanslight.otf");
        v.setTypeface(myTypeFace);
        v.setText(itemList.get(position));
        return v;
    }

}

Then i use

List<CharSequence> itemList = new ArrayList<CharSequence>(
            Arrays.asList(items));

    mySpinnerArrayAdapter = new   CustomAdapter(context,android.R.layout.simple_spinner_item,itemList); 
    spinner.setAdapter(mySpinnerArrayAdapter);

After doing this, my adapter is empty. Can anyone please help me ? The items contains a list of countries.

Kind Regards,

解决方案

Try

public View getView(int position, View convertView, ViewGroup parent) {

    LayoutInflater inflater = getLayoutInflater();
            View row = inflater.inflate(yourRowlayout, parent,
                    false);
       TextView make = (TextView) row.findViewById(R.id.Make);
        Typeface myTypeFace = Typeface.createFromAsset(context.getAssets(),
                "fonts/gilsanslight.otf");
        v.setTypeface(myTypeFace);
        v.setText(itemList.get(position));
        return row;
    }


public View getDropDownView(int position, View convertView, ViewGroup parent) {

        LayoutInflater inflater = getLayoutInflater();
                View row = inflater.inflate(yourRowlayout, parent,
                        false);
           TextView make = (TextView) row.findViewById(R.id.Make);
            Typeface myTypeFace = Typeface.createFromAsset(context.getAssets(),
                    "fonts/gilsanslight.otf");
            v.setTypeface(myTypeFace);
            v.setText(itemList.get(position));
            return row;
        }
