Question

我有一个自定义listview baseadapter类，其中包含手机上已安装应用的列表视图。

enter image description here

基本上我想在listview中为appname设置自定义字体。我尝试用id设置这样的字体并设置字体;但是，它无法在我的baseadapter类中的任何地方解析/完成。

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

我做了很多研究

How to set custom font for android listview?

但是这对我的baseadapter和需求来说是一个非常奇怪的情况，所以到目前为止我还是无法提供解决方案。

BaseAdapter类：

public class ApkAdapter extends BaseAdapter {

我将如何根据自己的情况实现这一目标？

Answer 1

而不是使用此

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

试试这个

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

Answer 2

它并没有那么糟糕。

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

哈哈哈，我遇到了同样的问题。我也尝试过在我的定制适配器上解决这个问题。 ;）

Answer 3

只需定义一个自定义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);
}
}

然后在xml中使用此类（及其包地址）而不是：

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

Answer 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();
        }

Answer 5

如果要设置字体，请检查此基本适配器：

 var num = 19683, c=0;
    for(var i=1; i<=num; i++){
      if((num%i===0)&&(i*i*i === num)){
        c = c+1;
      }
    }
    if(c > 0) {
     console.log('Yes')
    } else console.log('No');
