我在整个应用程序中使用自定义字体（顺便说一句，我沮丧地发现您必须以编程方式手动应用到每个控件！），我需要将它应用到列表视图。问题是我看不到将列表字体中使用的 textview 设置为我的自定义字体的位置（因为我从不实例化它 - 这一切都由适配器负责）。
我最理想的是能够使用这样的适配器：
new ArrayAdapter(Context context, TextView textView, List<T> objects)
这样我就可以做到： textView.setTypeface 在填充我的列表之前。有谁知道是否有办法按照这些方式做某事？
如果您不想创建新类，可以在创建适配器时覆盖 getView 方法，这是一个带有标题和副标题的 simpleAdapter 示例：
Typeface typeBold = Typeface.createFromAsset(getAssets(),"fonts/helveticabold.ttf");
Typeface typeNormal = Typeface.createFromAsset(getAssets(), "fonts/helvetica.ttf");
SimpleAdapter adapter = new SimpleAdapter(this, items,R.layout.yourLvLayout, new String[]{"title",
"subtitle" }, new int[] { R.id.rowTitle,
R.id.rowSubtitle }){
@Override
public View getView(int pos, View convertView, ViewGroup parent){
View v = convertView;
if(v== null){
LayoutInflater vi = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v=vi.inflate(R.layout.yourLvLayout, null);
}
TextView tv = (TextView)v.findViewById(R.id.rowTitle);
tv.setText(items.get(pos).get("title"));
tv.setTypeface(typeBold);
TextView tvs = (TextView)v.findViewById(R.id.rowSubtitle);
tvs.setText(items.get(pos).get("subtitle"));
tvs.setTypeface(typeNormal);
return v;
}
};
listView.setAdapter(adapter);
其中 items 是您的地图 ArrayList
希望有帮助
您不能那样做，因为您传递给 ArrayAdapter 的文本视图资源在每次使用时都会被夸大。
您需要创建自己的适配器并提供自己的视图。
您的适配器的一个示例可能是
public class MyAdapter extends BaseAdapter {
private List<Object> objects; // obviously don't use object, use whatever you really want
private final Context context;
public CamAdapter(Context context, List<Object> objects) {
this.context = context;
this.objects = objects;
}
@Override
public int getCount() {
return objects.size();
}
@Override
public Object getItem(int position) {
return objects.get(position);
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
Object obj = objects.get(position);
TextView tv = new TextView(context);
tv.setText(obj.toString()); // use whatever method you want for the label
// set whatever typeface you want here as well
return tv;
}
}
然后你可以这样设置
ListView lv = new ListView(this);
lv.setAdapter(new MyAdapter(objs));
希望这能让你继续前进。
看起来构造函数是错误的
将其更改为：
public MyAdapter (Context context, List<Object> objects) {
this.context = context;
this.objects = objects;
}
它对我来说效果很好。
像这样尝试阵列适配器::
Typeface typeNormal = Typeface.createFromAsset(getAssets(), "roboto_lite.ttf");
timearray = new ArrayAdapter<String>(DetailsActivity.this,R.layout.floorrow,R.id.txt, flor) {
public View getView(int pos, View convertView, android.view.ViewGroup parent) {
View v = convertView;
if (v == null) {
LayoutInflater vi = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate(R.layout.floorrow, null);
}
TextView tv = (TextView)v.findViewById(R.id.txt);
tv.setText(flor.get(pos));
tv.setTypeface(typeNormal);
return v;
};
};
lv_building.setAdapter(timearray);
除了 Moisés Olmedo 的响应之外 - 一个没有创建新类的替代变体：
tf = Typeface.createFromAsset(getAssets(), fontPath);
recordsAdapter = new SimpleCursorAdapter(this, R.layout.item1, cursor, from, to);
recordsAdapter.setViewBinder(new SimpleCursorAdapter.ViewBinder() {
public boolean setViewValue(View view, Cursor cursor, int columnIndex) {
if (columnIndex == 1) {
final TextView tv = (TextView) view;
tv.setTypeface(tf);
}
return false;
}
});
首先将字体文件复制并粘贴到 assets/fonts 文件夹中。然后识别文本视图。
Typeface font=Typeface.createFromAsset(activity.getAssets(), "fonts/<font_file_name>.ttf");
holder.text.setTypeface(font);
holder.text.setText("your string variable here");
您可以按照以下步骤设置基本适配器可能会对您有所帮助
定义您的基本适配器
public class LessonAdapter extends BaseAdapter {
private Context mContext;
public LessonAdapter(Context mContext, ArrayList<String> titles) {
super();
this.mContext = mContext;
}
public int getCount() {
// TODO Auto-generated method stub
if (titles!=null)
return titles.size();
else
return 0;
}
public Object getItem(int arg0) {
// TODO Auto-generated method stub
return null;
}
public long getItemId(int arg0) {
// TODO Auto-generated method stub
return 0;
}
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) mContext
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View v = convertView;
try
{
if (v == null) {
v = inflater.inflate(R.layout.lesson_item, null);
}
TextView title = (TextView) v.findViewById(R.id.title);
Typeface tf = Typeface.createFromAsset(getAssets(),
"fonts/Rabiat_3.ttf");
title.setTypeface(tf);
title.setText(titles.get(position).toString());
}
catch (Exception e) {
Log.d("searchTest", e.getMessage());
}
return v;
}
}
通过 TypeFace 方法，您可以通过在 Assets 中添加文件夹“Fonts”来设置字体，然后在“Fonts”文件夹中添加字体
然后设置你的适配器
adapter = new LessonAdapter(LessonsTitle.this, titles);
setListAdapter(adapter);
holder.txt_name.setTypeface(Typeface.createFromAsset(activity.getAssets(), "font/nasimbold.ttf"));
