有一种方法可以获得layoutInflater:

LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

另一种方式是:

LayoutInflater inflater = LayoutInflater.from(context);

第三个(当我参加活动时)是:

LayoutInflater inflater = getLayoutInflater();

那么他们之间有什么区别？

请注意,当我将第三个inflater发送到我的适配器时,我的应用程序工作.但是当我发送上下文并通过第二种方式创建了inflater时,它没有!

我正在用Fragments API支持重写我的应用程序.在原始应用程序中,我有一个AlertDialog这样的:

    LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View view = inflater.inflate(R.layout.button_dialog, null);
    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setView(view);
    ListView mListView = (ListView) view.findViewById(R.id.mblist);
    builder.setTitle(getString(R.string.sysinfo)).setNeutralButton(
            getString(R.string.okay), null);
    Cursor dcursor = propManager.propCursor();
    if (dcursor.moveToFirst()) {
        startManagingCursor(dcursor);
        String[] from = { Constants.NAME_DET,
                Constants.VALUE_DET };
        int[] to = { R.id.mbname, R.id.mbvalue };
        SimpleCursorAdapter dadapter = new SimpleCursorAdapter(this,
                R.layout.info_list_row, dcursor, from, to);
        mListView.setAdapter(dadapter);
    }
    final Dialog dialog = builder.create();
    dialog.show();

如何通过DialogFragment显示相同的对话框？我已阅读文档,但无法弄清楚如何继续这样做.
