Question

我为listView使用自定义适配器，我想用自定义字体制作textView。 listView是片段： todolist_fragment.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
>

<ListView
    android:id="@+id/checkable_list"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    />

todolistfragment.java

public class toDoListFragment扩展了Fragment {

ListView checkableList;
Button showSelectedButton;

List<itemsModel> itemsList;

public toDoListFragment() {
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

    View rootView = inflater.inflate(R.layout.fragment_todolist, container, false);

    checkableList = rootView.findViewById(R.id.checkable_list);

    itemsList = new ArrayList<>();
    itemsList.add(new itemsModel(false, "item1"));
    itemsList.add(new itemsModel(false, "item2"));
    itemsList.add(new itemsModel(false, "item3"));
    itemsList.add(new itemsModel(false, "item4"));
    itemsList.add(new itemsModel(false, "item5"));
    itemsList.add(new itemsModel(false, "item6"));
    itemsList.add(new itemsModel(false, "item7"));

    final customList adapter = new customList(getActivity(), itemsList);

    checkableList.setAdapter(adapter);

    checkableList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
            itemsModel model = itemsList.get(i);

            if(model.isSelected())
                model.setSelected(false);
            else
                model.setSelected(true);

            itemsList.set(i, model);

            adapter.updateRecords(itemsList);
        }
    });


    return rootView;
}

}

所以我创建了customList.java：

public class customList extends BaseAdapter {

Activity activity;
List<itemsModel> itemsList;
LayoutInflater inflater;

public customList(Activity activity) {
    this.activity = activity;
}

public customList(Activity activity, List<itemsModel> itemsList) {
    this.activity = activity;
    this.itemsList = itemsList;

    inflater = activity.getLayoutInflater();
}

@Override
public int getCount() {
    return itemsList.size();
}

@Override
public Object getItem(int i) {
    return i;
}

@Override
public long getItemId(int i) {
    return i;
}

@Override
public View getView(int i, View view, ViewGroup viewGroup) {
    ViewHolder holder = null;
    if(view == null){
        view = inflater.inflate(R.layout.list_view_item_row, viewGroup, false);

        holder = new ViewHolder();

        holder.itemText = view.findViewById(R.id.itemName);
        holder.checkBox = view.findViewById(R.id.checkboxIcon);

        view.setTag(holder);
    }else
        holder = (ViewHolder) view.getTag();

    itemsModel model = itemsList.get(i);

    holder.itemText.setText(model.getItemsList());

    if(model.isSelected())
        holder.checkBox.setBackgroundResource(R.drawable.checked);

    else
        holder.checkBox.setBackgroundResource(R.drawable.check);

    return view;
}

public void updateRecords(List<itemsModel> itemsList){
    this.itemsList = itemsList;

    notifyDataSetChanged();
}

class ViewHolder{
    TextView itemText;
    ImageView checkBox;
}

}

和布局＆＃34; list_view_item_row.xml＆＃34;是使用imageview复选框和textview项目的布局：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?android:attr/activatedBackgroundIndicator"
android:minHeight="?android:attr/listPreferredItemHeightSmall"
android:padding="5dp" >

<ImageView
    android:id="@+id/checkboxIcon"
    android:layout_width="25dp"
    android:layout_height="25dp"
    android:layout_alignParentRight="true"
    android:layout_alignParentEnd="true"
    android:layout_marginRight="10dp"
    android:layout_marginEnd="10dp"
    android:layout_centerVertical="true"
    android:background="@drawable/check"/>


<TextView
    android:id="@+id/itemName"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerVertical="true"
    android:layout_toLeftOf="@+id/checkboxIcon"
    android:layout_toStartOf="@+id/checkboxIcon"
    android:padding="10dp"
    android:text="Item Name"
    android:textColor="@android:color/black"
    android:textAppearance="?android:attr/textAppearanceListItemSmall"
    />

我手动设置自定义字体...像这样：

TextView textView;
   textView = rootView.findViewById(R.id.text1); 
   Typeface customFontBold = Typeface.createFromAsset(getActivity().getAssets(), "fonts/Assistant-Bold.ttf");
   textView.setTypeface(customFontBold);

我可以在哪里设置自定义字体？谢谢。

在课堂上做出改变试试这个

public class customList extends BaseAdapter {
        Activity activity;
        List<itemsModel> itemsList;
        LayoutInflater inflater;
        private Typeface customFontBold;
        public customList(Activity activity) {
            this.activity = activity;
        }

        public customList(Activity activity, List<itemsModel> itemsList) {
            this.activity = activity;
            this.itemsList = itemsList;
            inflater = activity.getLayoutInflater();
            customFontBold = Typeface.createFromAsset(getActivity().getAssets(), "fonts/Assistant-Bold.ttf");
        }

        @Override
        public int getCount() {
            return itemsList.size();
        }

        @Override
        public Object getItem(int i) {
            return i;
        }

        @Override
        public long getItemId(int i) {
            return i;
        }

        @Override
        public View getView(int i, View view, ViewGroup viewGroup) {
            ViewHolder holder = null;
            if (view == null) {
                view = inflater.inflate(R.layout.list_view_item_row, viewGroup, false);

                holder = new ViewHolder();

                holder.itemText = view.findViewById(R.id.itemName);
                holder.checkBox = view.findViewById(R.id.checkboxIcon);
                holder.itemText.setTypeface(customFontBold);
                view.setTag(holder);
            } else
                holder = (ViewHolder) view.getTag();

            itemsModel model = itemsList.get(i);

            holder.itemText.setText(model.getItemsList());

            if (model.isSelected())
                holder.checkBox.setBackgroundResource(R.drawable.checked);

            else
                holder.checkBox.setBackgroundResource(R.drawable.check);

            return view;
        }

        public void updateRecords(List<itemsModel> itemsList) {
            this.itemsList = itemsList;

            notifyDataSetChanged();
        }

        class ViewHolder {
            TextView itemText;
            ImageView checkBox;
        }
    }

我使用了akhilesh0707答案，但我改变了它。

var data = new ObservableDataSource<Point>();

for (int i = 0; i < xvalues.Count(); i++)
{
data.Collection.Add(new Point(Convert.ToDouble(xvalues[i].Replace('.', ','), new CultureInfo("de-DE")) + xoffset, Convert.ToDouble(yaxes4Values[i].Replace('.', ','), new CultureInfo("de-DE"))));
}

LineGraph line = new LineGraph(data);
this.y2.Children.Add(line);

感谢akhilesh0707。
