Question

我正在使用RecyclerView来显示三个不同的文字，我想为每个文本应用自定义Typeface。现在在ViewHolder下的我的适配器中，我放了Typeface代码，但不知道如何将它们应用到每个textView。

Adapter.java

public class Adapter extends RecyclerView.Adapter<Adapter.ViewHolder> {

List<AdapterData> mItems;

public Adapter() {
    super();
    mItems = new ArrayList<>();
    AdapterData data = new AdapterData();
    data.setTextOne("Title 1");
    data.setTextTwo("Title 2");
    data.setTextThree("Title 3");
    mItems.add(data);

    data = new AdapterData();
    data.setTextOne("Title 1");
    data.setTextTwo("Title 2");
    data.setTextThree("Title 3");

    data = new AdapterData();
    data.setTextOne("Title 1");
    data.setTextTwo("Title 2");
    data.setTextThree("Title 3");
    mItems.add(data);


}

@Override
public ViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
    View v = LayoutInflater.from(viewGroup.getContext())
            .inflate(R.layout.cardview_items, viewGroup, false);
    return new ViewHolder(v);
}

@Override
public void onBindViewHolder(ViewHolder viewHolder, int i) {
    AdapterData data = mItems.get(i);
    viewHolder.textOne.setText(data.getTextOne());
    viewHolder.textTwo.setText(data.getTextTwo());
    viewHolder.textThree.setText(data.getTextThree());

}


@Override
public int getItemCount() {

    return mItems.size();
}

class ViewHolder extends RecyclerView.ViewHolder{

    public TextView textOne;
    public TextView textTwo;
    public TextView textThree;

    Typeface customTypeOne = Typeface.createFromAsset(itemView.getContext().getAssets(), "fonts/Typeface One.ttf");
    Typeface customTypeTwo = Typeface.createFromAsset(itemView.getContext().getAssets(), "fonts/Typeface Two.ttf");
    Typeface customTypeThree = Typeface.createFromAsset(itemView.getContext().getAssets(), "fonts/Typeface Three.ttf");


    public ViewHolder(View itemView) {
        super(itemView);
        textOne = (TextView)itemView.findViewById(R.id.textView1);
        textTwo = (TextView)itemView.findViewById(R.id.textView2);
        textThree = (TextView)itemView.findViewById(R.id.textView3);


    }
}
}

Answer 1

class ViewHolder extends RecyclerView.ViewHolder {

        public TextView textOne;
        public TextView textTwo;
        public TextView textThree;

        Typeface customTypeOne = Typeface.createFromAsset(itemView.getContext().getAssets(), "fonts/Typeface One.ttf");
        Typeface customTypeTwo = Typeface.createFromAsset(itemView.getContext().getAssets(), "fonts/Typeface Two.ttf");
        Typeface customTypeThree = Typeface.createFromAsset(itemView.getContext().getAssets(), "fonts/Typeface Three.ttf");


        public ViewHolder(View itemView) {
            super(itemView);
            textOne = (TextView) itemView.findViewById(R.id.textView1);
            textOne.setTypeface(customTypeOne);
            textTwo = (TextView) itemView.findViewById(R.id.textView2);
            textTwo.setTypeface(customTypeTwo);
            textThree = (TextView) itemView.findViewById(R.id.textView3);
            textThree.setTypeface(customTypeThree);
        }
    }

Answer 2

您实际上只需将字体添加到textview：

public ViewHolder(View itemView) {
    super(itemView);
...
textOne.setTypeface(customTypeOne)
...

Answer 3

您可以使用setTypeface（）方法在yout textview上设置创建的字体：

textOne.setTypeface(customTypeOne);
textTwo.setTypeface(customTypeTwo);
textThree.setTypeface(customTypeThree);

我还建议你在github上看书法。它是一个有效处理字体困境的强大库：）

Answer 4

Typeface myTypeface = Typeface.createFromAsset(getAssets(), "fonts/myFont.ttf");
viewHolder.textOne.setTypeface(myTypeface);
viewHolder.textOne.setText(data.getTextOne());

Answer 5

public class Adapter extends RecyclerView.Adapter<Adapter.ViewHolder> {

List<AdapterData> mItems;

public Adapter() {
    super();
    mItems = new ArrayList<>();
    AdapterData data = new AdapterData();
    data.setTextOne("Title 1");
    data.setTextTwo("Title 2");
    data.setTextThree("Title 3");
    mItems.add(data);

    data = new AdapterData();
    data.setTextOne("Title 1");
    data.setTextTwo("Title 2");
    data.setTextThree("Title 3");

    data = new AdapterData();
    data.setTextOne("Title 1");
    data.setTextTwo("Title 2");
    data.setTextThree("Title 3");
    mItems.add(data);


}

@Override
public ViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
    View v = LayoutInflater.from(viewGroup.getContext())
            .inflate(R.layout.cardview_items, viewGroup, false);
    return new ViewHolder(v);
}

@Override
public void onBindViewHolder(ViewHolder viewHolder, int i) {
    AdapterData data = mItems.get(i);
    viewHolder.textOne.setText(data.getTextOne());
    viewHolder.textTwo.setText(data.getTextTwo());
    viewHolder.textThree.setText(data.getTextThree());

}


@Override
public int getItemCount() {

    return mItems.size();
}

class ViewHolder extends RecyclerView.ViewHolder{

    public TextView textOne;
    public TextView textTwo;
    public TextView textThree;

    Typeface customTypeOne = Typeface.createFromAsset(itemView.getContext().getAssets(), "fonts/Typeface One.ttf");
    Typeface customTypeTwo = Typeface.createFromAsset(itemView.getContext().getAssets(), "fonts/Typeface Two.ttf");
    Typeface customTypeThree = Typeface.createFromAsset(itemView.getContext().getAssets(), "fonts/Typeface Three.ttf");


    public ViewHolder(View itemView) {
        super(itemView);
        textOne = (TextView)itemView.findViewById(R.id.textView1);
        textTwo = (TextView)itemView.findViewById(R.id.textView2);
        textThree = (TextView)itemView.findViewById(R.id.textView3);


        textOne.setTypeface(customTypeOne);
        textTwo.setTypeface(customTypeTwo);
        textThree.setTypeface(customTypeThree);


    }
}
}
