为ListView设置字体，Android

Question

我花了一整天的时间寻找答案，找到了很多，但都不是我需要的。因此，我有一个非常简单的ListView菜单和一个TextView项目文件。我想为菜单中的项目设置Segoe打印字体，我知道，我需要适配器，但我做不到。救命！！！

menu.xml：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
       android:orientation="vertical"
       android:layout_width="fill_parent"
       android:layout_height="fill_parent">
    <LinearLayout android:id="@+id/menu_top"
       android:orientation="vertical"
       android:layout_width="fill_parent"
       android:layout_height="wrap_content"
       android:background="@drawable/menu_top">
       </LinearLayout>
<ListView 
          android:id="@+id/ListView_Menu"
          android:layout_width="fill_parent"
          android:layout_height="fill_parent"
          android:background="@drawable/fon_android"
          android:divider="@drawable/menu_line"
          android:textStyle="bold" >
</ListView>
</LinearLayout>

menu_item.xml：

<?xml version="1.0" encoding="utf-8"?>
<TextView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/menu_prop"
android:layout_width="fill_parent"
android:textSize="19px"
android:text="test string"
android:layout_gravity="left"
android:layout_height="wrap_content"
android:shadowRadius="5"
android:textColor="@color/menu_color"
android:shadowDy="3"
android:shadowDx="3" />

Main_Menu.java的一部分：

public class Main_menu extends Activity {
    @Override
        public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.menu);
        ListView menuList = (ListView) findViewById(R.id.ListView_Menu);
        String[] items = { 
                getResources().getString(R.string.system),
                getResources().getString(R.string.convert),
                getResources().getString(R.string.forks),
                getResources().getString(R.string.margin)};
        ArrayAdapter<String> adapt = new ArrayAdapter<String>(this,R.layout.menu_item, items);
    menuList.setAdapter(adapt);
}

CustomAdapter.java:

public class CustomAdapter extends ArrayAdapter<String> {
       public CustomAdapter(Context context, int resource, String[] objects) {
    super(context, resource, objects);
    // TODO Auto-generated constructor stub
}
    public View getView (int position, View convertView, ViewGroup parent) {
              View view = super.getView(position, convertView, parent);
              TextView textView = (TextView) view.findViewById(R.id.menu_prop);
              Typeface font = Typeface.createFromAsset(getAssets(), "segoe_print.ttf"); 
              textView.setTypeface(font);
            return textView;
       }
    private AssetManager getAssets() {
        // TODO Auto-generated method stub
        return null;
    }
  }

字体不变。。。

Answer 1

view.txtViewTitle.setTypeface(Typeface.createFromAsset(parent
                .getContext().getAssets(), "fonts/DroidSerif.ttf"));

Answer 2

这里是自定义适配器的代码：

private class CostumiseAdapter extends ArrayAdapter<item>{
public CostumiseAdapter(ArrayList<item> items) {
 super(getActivity(), 0, items);
}
@Override
public View getView(int position, View convertView, ViewGroup parent){
 if(convertView == null){
convertView = getActivity().getLayoutInflater().inflate(R.layout.scroll_fragment, null);
}
Item item = getItem(position);
TextView text = (TextView) convertView.findViewById(R.id.text_view);
text.setText(item.mString);
RadioButton b1 = (RadioButton) convertView.findViewById(R.id.radio_b1);
b1.setChecked(item.mB1);
RadioButton b2 = (RadioButton) convertView.findViewById(R.id.radio_b2);
b2.setChecked(item.mB2);
CheckBox cB = (CheckBox) convertView.findViewById(R.id.check_box);
cB.setChecked(item.mB2);
return convertView;
}
}

我从http://androide-examples.blogspot.com/2013/11/android-scroll-list.html有关完整示例，请参阅。

在这个例子中有一些语义错误。所以你必须将一些项目固定为项目（大写）。。。

您需要创建一个自定义适配器来设置自定义字体。这是最小代码：

  public class CustomAdapter extends ArrayAdapter<String> {
   //Contructor here
       public View getView (int position, View convertView, ViewGroup parent) {
              View view = super.getView(position, convertView, parent);
              TextView textView = (TextView) view.findViewById(R.id.myTextView);
             // Here you set the typeface as you do for the TextView 
              textView.setTypeFace(....);
       }
  }

这应该为您的Listview提供自定义字体。

我找到了一个设计！首先，我为Adapter创建了另一个类：

public class Typefaces {
    private static final Hashtable<String, Typeface> cache = new Hashtable<String, Typeface>();
    public static Typeface get(Context c, String name) {
    synchronized (cache) {
    if (!cache.containsKey(name)) {
    String path = "fonts/"+name;
    try {
    Typeface t = Typeface.createFromAsset(c.getAssets(), path);
    cache.put(name, t);
    } catch (Exception e) {
    e.printStackTrace();
    }
    }
    return cache.get(name);
    }
    }
    }

然后在主适配器中，我添加了两个字符串：

Typeface tf = Typefaces.get(getContext(), "tahoma.ttf");
        holder.txtTitle.setTypeface(tf);

仅此而已！它在工作！））感谢大家的帮助和回答。

Answer 5

在xml:中尝试

android:fontFamily="somefont.ttf"

从android 4.1+可以使用以下字体：http://robotofont.com/

android:fontFamily="sans-serif"  
android:fontFamily="sans-serif-thin"        
android:fontFamily="sans-serif-light"     
android:fontFamily="sans-serif-condensed" 

您也可以通过程序设置字体：

TextView t = (TextView) findViewById(R.id.name);
Typeface font = Typeface.createFromAsset(getAssets(),"font/somefont.ttf");
t.setTypeface(font);

将字体文件放在文件夹中。。。
