android– 为AlertDialog的MultiSelectItems设置自定义字体(字体)

概述我已经能够将自定义字体应用于Alert对话框的标题,如下所示：AlertDialog.Builderbuilder=newAlertDialog.Builder(this);TextViewMytitle=newTextView(this);Mytitle.setText("MyCustomtitle");Mytitle.setTextSize(20);Mytitle.setPadding(5,15,5,5);My

我已经能够将自定义字体应用于Alert对话框的标题,如下所示：

 AlertDialog.Builder builder = new AlertDialog.Builder(this); TextVIEw MyTitle = new TextVIEw(this); MyTitle.setText("My Custom Title");  MyTitle.setTextSize(20); MyTitle.setpadding(5, 15, 5, 5); MyTitle.setGravity(Gravity.CENTER); MyTitle.setTypeface(Typeface.createFromAsset(this.getAssets(), "myFont.ttf")); builder.setCustomTitle(MyTitle);

警报对话框显示由下面一行填充的多选项目列表.

 builder.setMultiChoiceItems(MyItems, MycheckedItems, MyDialogListener); //where MyItems is CharSequence[] Array, MycheckedItems => boolean[] array, //MyDialogListener => DialogInterface.OnMultiChoiceClickListener

我也希望将字体应用于这些多选项.我怎样才能做到这一点？可能吗？

解决方法:

AlertDialog.Builder使用AlertController.AlertParams构建对话框.我检查了AlertDialog.Builder #create()调用AlertController.AlertParams #application()如果设置了项目,则创建ListVIEw并分配适配器(AlertParams#createListView()).

我基于createListVIEw源创建了自定义适配器并修改了androID单元格布局：

public static class TypefaceDialog extends DialogFragment {        private static final CharSequence[] items = {            "A", "B", "C", "D", "E", "F", "G"        };        private static final boolean[] checked = {            true, false, false, true, true, false, false        };        @OverrIDe        public Dialog onCreateDialog(Bundle savedInstanceState) {            final Typeface FontTypeface = Typeface.createFromAsset(getActivity().getAssets(), "Arial Bold.ttf");            listadapter adapter = new ArrayAdapter<CharSequence>(                    getActivity(),                     androID.R.layout.select_dialog_multichoice,                     androID.R.ID.text1,                    items) {                @OverrIDe                public VIEw getVIEw(final int position, VIEw convertVIEw, VIEwGroup parent) {                    VIEw vIEw = super.getVIEw(position, convertVIEw, parent);                    CheckedTextVIEw textVIEw = (CheckedTextVIEw)vIEw.findVIEwByID(androID.R.ID.text1);                    textVIEw.setChecked(checked[position]);                    textVIEw.setTypeface(FontTypeface);                    textVIEw.setonClickListener(new VIEw.OnClickListener() {                        @OverrIDe                        public voID onClick(VIEw v) {                            CheckedTextVIEw vIEw = (CheckedTextVIEw)v;                            vIEw.setChecked(!vIEw.isChecked());                            checked[position] = vIEw.isChecked();                        }                    });                    return vIEw;                }            };            return new AlertDialog.Builder(getActivity())            .setAdapter(adapter, null)            .setPositivebutton("OK", null)            .create();        }    }
