Android的自定义字体列表视图

Question

我有我的android活动的自定义字体。

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); 
      header.setText(value); 

custom_list_text.xml

<TextView xmlns:android="http://schemas.android.com/apk/res/android" 
android:id="@+id/list_text" 
android:layout_width="match_parent" 
android:layout_height="wrap_content" 
android:textSize="18sp" 
android:textStyle="bold" 
android:text="@string/app_name" 
android:paddingLeft="6dip" />

Answer 1

这里是自定义适配器类和构造

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); 
} 

把你想要在你的资产文件夹中使用，并填写您的列表视图像这样的字体：

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