[英]How to set custom listview font for items in custom baseadapter class
我有一個自定義的listview baseadapter類,該類具有手機上已安裝的應用程序的listview。
本質上,我想在列表視圖中為應用程序名稱設置自定義字體。 我試圖用id設置這樣並設置字體; 但是,它無法在我的baseadapter類中的任何地方解決/完成。
appname = (TextView)findViewById(R.id.appname);
appname.setTypeface(Typeface.createFromAsset(getAssets(), "fonts/raleway-regular.otf"));
我做了很多研究
但是對於我的基本適配器和需求,這確實是一個很奇怪的情況,所以到目前為止,我一直無法提出解決方案。
BaseAdapter類:
public class ApkAdapter extends BaseAdapter {

我將如何針對自己的情況實現這一目標?
感興趣的
appname.setTypeface(Typeface.createFromAsset(getAssets(), "fonts/raleway-regular.otf"));
嘗試這個
Typeface fond = Typeface.createFromAsset(context.getAssets(), "YOYR FONT FROM asset folder");
appname.setTypeface(fond);
沒那么糟糕。
holder.apkName.setTypeface(Typeface.createFromAsset(context.getAssets(), "fonts/raleway-regular.otf"));
哈哈哈,我有同樣的問題。 我花了一些時間嘗試在我的自定義適配器上弄清楚這一點。 ;)
只需定義一個自定義TextView類,如下所示:
public class AryanTextView extends TextView {
public AryanTextView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
init();
}
public AryanTextView(Context context, AttributeSet attrs) {
super(context, attrs);
init();
}
public AryanTextView(Context context) {
super(context);
init();
}
private void init() {
Typeface tf = Typeface.createFromAsset(getContext().getAssets(),
"font/YourFont.ttf");
setTypeface(tf);
setTextSize(TypedValue.COMPLEX_UNIT_DIP, 20);
}
}
然后在您的xml中使用此類(及其包地址)而不是:
<com.example.uicomponents.AryanTextView
..../>
just change condition only ::-
if (convertView == null) {
convertView = inflater.inflate(R.layout.installed_apps, null);
holder = new ViewHolder();
holder.apkName = (TextView) convertView.findViewById(R.id.appname);
holder.ck1= (CheckBox)convertView.findViewById(R.id.checkBox1);
holder.packageName = (TextView) convertView.findViewById(R.id.app_package);
convertView.setTag(holder);
holder.apkName.appname.setTypeface(Typeface.createFromAsset(getAssets(), "fonts/raleway- regular.otf"));
//holder.ck1.setTag(packageList.get(position));
} else {
holder = (ViewHolder) convertView.getTag();
}
如果要設置字體,請檢查以下基本適配器:
public class AdapterListCitiesMarkets extends BaseAdapter {
private Context mContext;
private ArrayList<String> mMarketName;
public AdapterListCitiesMarkets(Context context, ArrayList<String> MarketName) {
mContext = context;
mMarketName = MarketName;
}
@Override
public int getCount() {
return mMarketName.size();
}
@Override
public Object getItem(int position) {
return position;
}
@Override
public long getItemId(int position) {
return position;
}
public View getView(final int position, View convertView, ViewGroup parent) {
convertView = G.layoutInflater.inflate(R.layout.list_lay_cities_markets, null);
TextView txtCityMarketName = (TextView) convertView.findViewById(R.id.txtCityMarketName);
TextView txtCityMarketDistance = (TextView) convertView.findViewById(R.id.txtCityMarketDistance);
txtCityMarketName.setTypeface(G.IranSans);
txtCityMarketDistance.setTypeface(G.IranSans);
txtCityMarketName.setText("فروشگاه : " + mMarketName.get(position));
notifyDataSetChanged();
return convertView;
}
}
