我的 android 活动有一个自定义字体.

I have a custom font for my android activity.

MainActivity.class

    private void initControls() {
    // TODO Auto-generated method stub
    header = (TextView) findViewById (R.id.tvAccommodations);
    lv = (ListView) findViewById (R.id.lvAccommodations);
    text = (TextView) findViewById (R.id.textView);

    Typeface tf = Typeface.createFromAsset(getAssets(),
            "fonts/heartbre.ttf");
    header.setTypeface(tf);
    text.setTypeface(tf);



    ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this,
                    R.array.abra_hotel, R.layout.custom_list_text);
            lv.setAdapter(adapter);

推荐答案

这是自定义适配器类和构造函数

Here is the custom adapter class and the constructor

class CustomAdapter extends ArrayAdapter<CharSequence>{

    Context context; 
    int layoutResourceId;    
    CharSequence data[] = null;
    Typeface tf; 

public CustomAdapter(Context context, int layoutResourceId, CharSequence[] data, String FONT ) { 
    super(context, layoutResourceId, data);
    this.layoutResourceId = layoutResourceId;
    this.context = context;
    this.data = data;
    tf = Typeface.createFromAsset(context.getAssets(), FONT);
}   

把你想使用的字体放在你的assets文件夹中，然后像这样填充你的listview:

Put the font you want to use in your assets folder and fill your listview like this:

listAdapter = new CustomAdapter(this, R.layout.custom_list_text, R.array.abra_hotel, "name_of_font.ttf");
