我有一个textview,当它被点击时,我在对话框中填充listView.这段代码以前工作正常,但今天却抛出了异常.

这是我的代码:

tvSelectedFont = (TextView)findViewById(R.id.lblQuoteSelectedFont);
    tvSelectedFont.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            ListView listView = new ListView(context);
            listView.setAdapter(new ArrayAdapter<String>(context, android.R.layout.simple_list_item_1,
                    new String[] {"Default", "Serif", "Monospace"}));
            final Dialog dialog = new Dialog(context);
            dialog.setContentView(listView);
            dialog.setTitle(R.string.txt_settings_QuotefontName);

            listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
                @Override
                public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                    String selectedTypeFace = ((TextView)view).getText().toString();
                    tvSelectedFont.setText(selectedTypeFace);
                    switch(selectedTypeFace)
                    {
                        case "Serif":
                            selectedQuoteTypeFace = Typeface.SERIF;
                            break;
                        case "Monospace":
                            selectedQuoteTypeFace = Typeface.MONOSPACE;
                            break;
                        default:
                            selectedQuoteTypeFace = Typeface.DEFAULT;
                            break;
                    }
                    tvQuoteTextSample.setTypeface(selectedQuoteTypeFace, selectedQuoteFontStyle);
                    dialog.dismiss();
                }
            }); …
