警报对话框中的TextView不会向下滚动

Question

我从网站获取数据并放置在文本视图中,以便我可以使用setGravity(Gravity.CENTER)将其居中.但是,当我将文本视图放在警告对话框中时,我无法再向下滚动以查看消息的结尾.有人可以帮我解决这个问题吗？谢谢

    TextView msg1=new TextView(Welcome.this);
   //Takes data from a website
    msg1.setText(Html.fromHtml(getText("http://www.cellphonesolutions.net/welcome-en")));
    msg1.setGravity(Gravity.CENTER);
    LinearLayout dialogLayout = new LinearLayout(Welcome.this);

    dialogLayout.addView(msg1);
    dialogLayout.setOrientation(LinearLayout.VERTICAL);
    AlertDialog welcome = new AlertDialog.Builder(Welcome.this).create();
    welcome.setView(dialogLayout);

    welcome.setButton("OK", new DialogInterface.OnClickListener() {

        @Override
        public void onClick(DialogInterface dialog, int which) {
        //rest of the code....

您可以尝试更改代码,如下所示:

    dialogLayout.addView(msg1);
    dialogLayout.setOrientation(LinearLayout.VERTICAL);
    AlertDialog welcome = new AlertDialog.Builder(Welcome.this).create();
    ScrollView scrollPane = new ScrollView(this);
    scrollPane.addView(dialogLayout);
    welcome.setView(scrollPane);
