如何使AlertDialog List可滚动Android [重复]

Question

我在 AlertDialog 中有一个列表；

 public void thesaurusBtnAction(){
    // setup the alert builder
    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setTitle("Synonyms List");

    // add a list
    String[] someList = {"a", "b", "c", "d", "e","a","b"};
    builder.setItems(someList, new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            switch (which) {
                case 0: 
                case 1:
                case 2:
                case 3:
                case 4:
            }
        }
    });

    // create and show the alert dialog
    AlertDialog dialog = builder.create();
    dialog.show();
}

我想将此处的列表设为可滚动列表，并将 AlertDialog 的大小限制为一定的大小，因为 AlertDialog 会随着列表的增长尝试增加其大小。

 public void thesaurusBtnAction(){
    // setup the alert builder
    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setTitle("Synonyms List");
    builder.setView(LayoutInflater.from(this).inflate(R.layout.dialoglayout,null));


    // create and show the alert dialog
    AlertDialog dialog = builder.create();
    dialog.show();
}

dialoglayout.xml

<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:scrollbarAlwaysDrawVerticalTrack="true"
    android:scrollbars="vertical">
    <!--Any of your code-->
    <ListView
        android:layout_width="match_parent"
        android:layout_height="match_parent"></ListView>
</LinearLayout>

将布局包含在 ScrollView 中。在封闭的布局中，您可以将 android:scrollbars 设置为垂直。使用 builder.setView 在对话框中显示 ScrollView。
