我刚刚在一个正在进行的匹配游戏中遇到过这个问题.我的解决方案并不简单,但我想使用自定义字体,我没有看到使用2.2 Android界面(这是我的目标)的简单方法.诀窍是在显示之前将OnShowListener附加到警报对话框.在该侦听器中,从ListView中获取listadapter并使用代理对象将其包装,该代理对象转发除getView之外的所有调用.在该函数中,将View强制转换为TextView,设置字体和大小,然后返回视图.这是我的代码：

// Add your list with builder up here
        AlertDialog alert = builder.create();
        alert.setOnShowListener(new OnShowListener() {

            @Override
            public void onShow(DialogInterface alert) {
                ListView listView = ((AlertDialog)alert).getListView();
                final listadapter originalAdapter = listView.getAdapter();

                listView.setAdapter(new listadapter()
                {

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

                    @Override
                    public Object getItem(int id) {
                        return originalAdapter.getItem(id);
                    }

                    @Override
                    public long getItemId(int id) {
                        return originalAdapter.getItemId(id);
                    }

                    @Override
                    public int getItemViewType(int id) {
                        return originalAdapter.getItemViewType(id);
                    }

                    @Override
                    public View getView(int position,View convertView,ViewGroup parent) {
                        View view = originalAdapter.getView(position,convertView,parent);
                        TextView textView = (TextView)view;
                        textView.setTypeface(MyFontUtil.getTypeface(MyActivity,MY_DEFAULT_FONT));
                        textView.setTextColor(Color.bLACK);
                        textView.setTextSize(25); // FIXIT - absolute size 
                        return view;
                    }

                    @Override
                    public int getViewTypeCount() {
                        return originalAdapter.getViewTypeCount();
                    }

                    @Override
                    public Boolean hasStablEIDs() {
                        return originalAdapter.hasStablEIDs();
                    }

                    @Override
                    public Boolean isEmpty() {
                        return originalAdapter.isEmpty();
                    }

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

                    }

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

                    }

                    @Override
                    public Boolean areAllItemsEnabled() {
                        return originalAdapter.areAllItemsEnabled();
                    }

                    @Override
                    public Boolean isEnabled(int position) {
                        return originalAdapter.isEnabled(position);
                    }

                });

            }

        });


        alert.show();

如果您想在几周内在Android电子市场上看到它的实际效果.搜索Metaphyze(我的发布商ID).我还没决定叫什么. (这不是“FlashMatch Chinese I Free”.这是我的第一个游戏.这是一个孩子的匹配游戏.玩游戏并在结尾点击图片.你会看到带有样式列表的AlterDialog.).
