android更改listview字体和颜色

Question

我已经找到了许多不同的方法来实现这一点,但我不确定什么是最适合我的方案.

这是我的listview的Java代码:

ListView lv;
lv = (ListView) findViewById(R.id.favList);

这是列表的xml代码:

<ListView
        android:id="@+id/favList"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginBottom="40dp"
        android:layout_marginLeft="30dp"
        android:layout_marginRight="30dp"
        android:layout_marginTop="20dp"
        android:background="@android:color/transparent"
        android:cacheColorHint="@android:color/transparent"
        android:listSelector="@android:color/transparent" >
    </ListView>

对于文本视图,我会添加:

final Typeface fontList = Typeface.createFromAsset(assets, "optima-extra-black.ttf");
lv.setTypeface(fontList);

但这对listviews不起作用.在这种情况下如何更改字体？

我几乎就在那里......我需要访问我的资产,但我无法从我的自定义适配器中访问.我试过用final AssetManager assets = this.getAssets();但不会让我更进一步..

如何解决这个问题？

    class Myadapter extends BaseAdapter {

    LayoutInflater lif;
    ImageView sideArrow;
    TextView tv;


    public Myadapter(Context ctx) {
        lif = (LayoutInflater) ctx
                .getSystemService(LAYOUT_INFLATER_SERVICE);

    }

    @Override
    public int getCount() {

        return favarets.size();
    }

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

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

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {

        View vi = convertView;
        if (convertView == null)
            vi = lif.inflate(R.layout.inflate, null);
        sideArrow = (ImageView) vi.findViewById(R.id.imageViewsidemark);

        tv = (TextView) vi.findViewById(R.id.textFav);
        tv.setText(favarets.get(position));
        final AssetManager assets = this.getAssets();
        final Typeface tvFont = Typeface.createFromAsset(assets, "OPTIMA.TTF");
        tv.setTypeface(tvFont);

        tv.setTextColor(Color.BLACK);

        return vi;

我找到了解决方案:D

    public class Myadapter extends BaseAdapter {

    AssetManager assetManager = getAssets(); 

    LayoutInflater lif;
    ImageView sideArrow;
    TextView tv;


    public Myadapter(Context ctx) {
        lif = (LayoutInflater) ctx.getSystemService(LAYOUT_INFLATER_SERVICE);


    }

    @Override
    public int getCount() {

        return favarets.size();
    }

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

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


    @Override
    public View getView(int position, View convertView, ViewGroup parent) {

        View vi = convertView;
        if (convertView == null)
            vi = lif.inflate(R.layout.inflate, null);
        sideArrow = (ImageView) vi.findViewById(R.id.imageViewsidemark);


        tv = (TextView) vi.findViewById(R.id.textFav);
        tv.setText(favarets.get(position));

        final Typeface tvFont = Typeface.createFromAsset(assetManager, "OPTIMA.TTF");
        tv.setTypeface(tvFont);
        tv.setTextColor(Color.BLACK);

        return vi;
    }

}

列表视图本身不负责绘制项目,它使用适配器来创建列表项.此适配器创建一个视图以在需要时显示列表项.要更改用于显示列表项的字体,您必须更改适配器以返回包含新字体的视图.这可以在Adapter.getView方法中完成.如果您当前正在使用标准的Adapter实现,则可能需要对其进行子类化(或完全替换它).
