自定义微调适配器

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,

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; }
