Question

我有一个扩展到ListActivity的类，我想为其设置自定义字体。任何人都可以带我走过这个吗？我知道如何使用TextView的字体，但不知道ListActivity的字体。

public static class PunjabiBooks extends ListActivity{

    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        String[] mathList = new String[] {"Gurmukh Soch", "Books (Punjabi)", "Books (Hindi)", "Books (English)",
        "Annual Report"};
        setListAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, mathList));

    }

    @Override
    protected void onListItemClick(ListView l, View v, int position, long id) {
        // TODO Auto-generated method stub
        super.onListItemClick(l, v, position, id);
        Object o = this.getListAdapter().getItem(position);
        String keyword = o.toString();
        if (keyword.equals("Gurmukh Soch")){
            x = 0;
            try{
                Class ourClass = Class.forName("sukrit.trust.PublicationsTab$WebActivity");
                Intent ourIntent = new Intent(PunjabiBooks.this, ourClass);
                startActivity(ourIntent);
            }catch(ClassNotFoundException e){
                e.printStackTrace();
            }
        }else if(keyword.equals("Books (Punjabi)")){
            try{
                Class ourClass = Class.forName("sukrit.trust.Publications$PunjabiBooks");
                //  Intent ourIntent = new Intent(Publications.this, ourClass);
                //startActivity(ourIntent);
            }catch(ClassNotFoundException e){
                e.printStackTrace();
            }
        }else if(keyword.equals("Books (Hindi)")){
            try{
                Class ourClass = Class.forName("sukrit.trust.PublicationsTab$HindiBooks");
                //                  Intent ourIntent = new Intent(Publications.this, ourClass);
                //                  startActivity(ourIntent);
            }catch(ClassNotFoundException e){
                e.printStackTrace();
            }
        }else if(keyword.equals("Books (English)")){
            try{
                Class ourClass = Class.forName("sukrit.trust.PublicationsTab$EnglishBooks");
                //                  Intent ourIntent = new Intent(Publications.this, ourClass);
                //                  startActivity(ourIntent);
            }catch(ClassNotFoundException e){
                e.printStackTrace();
            }
        }else if(keyword.equals("Annual Report")){
            try{
                Class ourClass = Class.forName("sukrit.trust.PublicationsTab$AnnualReport");
                //                  Intent ourIntent = new Intent(Publications.this, ourClass);
                //                  startActivity(ourIntent);
            }catch(ClassNotFoundException e){
                e.printStackTrace();
            }
        }
    }

ListView本身并没有任何文字可以使用自定义字体。您需要处理提供此文本的类：Adapter。您的适配器负责在ListView中创建视图，包括（在这种情况下）相关的TextView。您需要创建一个自定义适配器（可能来自ArrayAdapter<String>），您可以在其中覆盖getView方法。最简单的解决方案可能是简单地调用父实现的getView，然后使用TextView从android.R.layout.simple_list_item_1布局中找到相关的View.findViewById（您可以查找它，但是我相信相关的id是text1），然后设置你已经知道如何做的自定义字体。这可能看起来像：

public class CustomAdapter extends ArrayAdapter<String> {
    // Appropriate Constructor here
    // ...

    public View getView (int position, View convertView, ViewGroup parent) {
        View view = super.getView(position, convertView, parent);
        TextView textView = (TextView) view.findViewById(android.R.id.text1);
        // Do your textView.setTypeface( ... ) stuff here
    }
}

Android中ListView的自定义字体？
