将文本设置为`EditText`

Question

我正在尝试将文字设置为自定义EditText中的AlertDialog。我正在使用以下代码。

........
........    
........
........
    case R.id.edit:
        LayoutInflater factory = LayoutInflater.from(this);
        final View textEntryView = factory.inflate(R.layout.editvslayout,
                null);
        new AlertDialog.Builder(this)
                .setTitle(
                        Messages.getString("OSListActivity.52") + item_cursor.getString(1)) //$NON-NLS-1$
                .setView(textEntryView)
                .setPositiveButton(Messages.getString("OSListActivity.53"), //$NON-NLS-1$
                        new DialogInterface.OnClickListener() {
                            public void onClick(DialogInterface dialog,
                                    int whichButton) {// TODO update path
                                // update desc
                                EditText evsname = (EditText) textEntryView
                                        .findViewById(R.id.vsname);
                                EditText evsdesc = (EditText) textEntryView
                                        .findViewById(R.id.vsdesc);
                                evsdesc.setText(folderdesc);
                                evsname.setText(foldername);
........
........    
........
........

然而，文字没有显示出来。为什么？我该如何解决这个问题？

修改FIX：

case R.id.edit:
    LayoutInflater factory = LayoutInflater.from(this);
    final View textEntryView = factory.inflate(R.layout.editvslayout,
            null);
    final EditText evsname = (EditText) textEntryView
                .findViewById(R.id.vsname);
    final EditText evsdesc = (EditText) textEntryView
            .findViewById(R.id.vsdesc);
    evsdesc.setText(folderdesc);
    evsname.setText(foldername);
    new AlertDialog.Builder(this)
            .setTitle(
                    Messages.getString("OSListActivity.52") + item_cursor.getString(1)) //$NON-NLS-1$
            .setView(textEntryView)
            .setPositiveButton(Messages.getString("OSListActivity.53"), //$NON-NLS-1$
                    new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog,
                                int whichButton) {
                            // code here
                            }
