如何为自定义baseadapter类中的项目设置自定义listview字体

I have a custom listview baseadapter class that has a listview of installed apps on the phone.

我有一个定制的listview baseadapter类，它有一个安装在手机上的应用程序的listview。

Essentially I want to set a custom font for the appname in the listview. I tried to set like this with the id and setting the typeface; however, it was unable to be resolved/done in everywhere in my baseadapter class.

本质上，我想为listview中的appname设置一个自定义字体。我试着像这样设置id和设置字体;但是，在我的baseadapter类中，它无法在任何地方得到解决。

appname = (TextView)findViewById(R.id.appname);
appname.setTypeface(Typeface.createFromAsset(getAssets(), "fonts/raleway-regular.otf"));

I have done a lot of research

我做了很多研究

How to set custom font for android listview?

如何为android listview设置自定义字体?

But this is a really weird situation with my baseadapter and needs, so I have been unable to produce a solution so far.

但这是一个非常奇怪的情况，我的基适配器和需要，所以我至今无法产生一个解决方案。

How would I go about achieving this for my situation?

对于我的处境，我该如何实现这个目标呢?

5 个解决方案

#1

intead of using this

使用这个,而不是

appname.setTypeface(Typeface.createFromAsset(getAssets(), "fonts/raleway-regular.otf"));

try this

试试这个

 Typeface fond = Typeface.createFromAsset(context.getAssets(), "YOYR FONT FROM asset folder");
    appname.setTypeface(fond);

#2

It's not that bad.

这不是那么糟糕。

holder.apkName.setTypeface(Typeface.createFromAsset(context.getAssets(), "fonts/raleway-regular.otf"));

Hahaha I had the same problem. Took me a couple tries to figure this out on my custom adapter too. ;)

哈哈哈，我也有同样的问题。我带了几个人试着在我的自定义适配器上弄明白这一点。,)

#3

Just define a custom TextView class like this:

像这样定义一个自定义TextView类:

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);
}
}

and then use this class (with its package address) in your xml instead of :

然后在xml中使用这个类(及其包地址)，而不是:

<com.example.uicomponents.AryanTextView
 ..../>

#4

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();
        }

#5

If you want to set typeface check this base adapter :

如果您想要设置字体，请检查此基础适配器:

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;
}

}
