Question

我没有找到符合我要求的任何代码。在getview和getdropdown视图中我应用了字体，但更改未反映在我的设计中请提前解决我的问题。

public class HintSpinnerAdapter  implements SpinnerAdapter, ListAdapter {

    protected static final int PIVOT = 1;

    protected SpinnerAdapter adapter;

    protected Context context;

    protected int hintLayout;

    protected int hintDropdownLayout;

    protected LayoutInflater layoutInflater;

    public HintSpinnerAdapter(
            SpinnerAdapter spinnerAdapter,
            int hintLayout, Context context) {

        this(spinnerAdapter, hintLayout, -1, context);
    }

    public HintSpinnerAdapter(SpinnerAdapter spinnerAdapter,
                              int hintLayout, int hintDropdownLayout, Context context) {
        this.adapter = spinnerAdapter;
        this.context = context;
        this.hintLayout = hintLayout;
        this.hintDropdownLayout = hintDropdownLayout;
        layoutInflater = LayoutInflater.from(context);
    }

    @Override
    public final View getView(int position, View convertView, ViewGroup parent) {
        // This provides the View for the Selected Item in the Spinner, not
        // the dropdown (unless dropdownView is not set).
        if (position == 0) {
            return getHintView(parent);
        }
        return adapter.getView(position - PIVOT, null, parent); // Could re-use
                                                 // the convertView if possible.
    }

    protected View getHintView(ViewGroup parent) {
        return layoutInflater.inflate(hintLayout, parent, false);
    }

    @Override
    public View getDropDownView(int position, View convertView, ViewGroup parent) {
        // Android BUG! http://code.google.com/p/android/issues/detail?id=17128 -
        // Spinner does not support multiple view types
        if (position == 0) {
            return hintDropdownLayout == -1 ?
              new View(context) :
              getHintDropdownView(parent);
        }

        // Could re-use the convertView if possible, use setTag...
        return adapter.getDropDownView(position - PIVOT, null, parent);
    }

    protected View getHintDropdownView(ViewGroup parent) {
        return layoutInflater.inflate(hintDropdownLayout, parent, false);
    }

    @Override
    public int getCount() {
        int count = adapter.getCount();
        return count == 0 ? 0 : count + PIVOT;
    }

    @Override
    public Object getItem(int position) {
        return position == 0 ? null : adapter.getItem(position - PIVOT);
    }

    @Override
    public int getItemViewType(int position) {
        return 0;
    }

    @Override
    public int getViewTypeCount() {
        return 1;
    }

    @Override
    public long getItemId(int position) {
        return position >= PIVOT ? adapter.getItemId(position - PIVOT) : position - PIVOT;
    }

    @Override
    public boolean hasStableIds() {
        return adapter.hasStableIds();
    }

    @Override
    public boolean isEmpty() {
        return adapter.isEmpty();
    }

    @Override
    public void registerDataSetObserver(DataSetObserver observer) {
        adapter.registerDataSetObserver(observer);
    }

    @Override
    public void unregisterDataSetObserver(DataSetObserver observer) {
        adapter.unregisterDataSetObserver(observer);
    }

    @Override
    public boolean areAllItemsEnabled() {
        return false;
    }

    @Override
    public boolean isEnabled(int position) {
        return position != 0; // Don't allow the 'hint' item to be picked.
    }
}

如何将自定义字体应用于我使用微调器适配器和列表适配器实现的微调器我没有使用数组适配器
