警報對話框中的TextView不會向下滾動

Question

我正在從網站獲取數據並放置在文本視圖中，以便我可以使用setGravity（Gravity.CENTER）將其居中。但是，當我將文本視圖放在警報對話框中時，我無法再向下滾動查看消息的結尾。有人可以幫我解決這個問題嗎？謝謝

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....

你可以試着改變這樣的代碼：

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);
