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....

Answer 1

您可以尝试更改以下代码：

    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);

警报对话框中的TextView不会向下滚动
