android - 警报对话框内的所有 EditText 都不可见

Question

我有一个警告对话框，里面有四个编辑文本。但只有三个是可见的，因为没有垂直滚动。所有编辑文本都在线性布局内。我尝试在布局周围添加 ScrollView ，但没有帮助。请帮忙。

我的代码是:

AlertDialog.Builder alert = new AlertDialog.Builder(MyActivity.this);
alert.setTitle("Title Here");

LinearLayout group = new LinearLayout(MyActivity.this);
group.setOrientation(LinearLayout.VERTICAL);
group.setVerticalScrollBarEnabled(true);

final TextView first = new TextView(MyActivity.this);
first.setText("first edit text");
group.addView(first );
final EditText firstEdit= new EditText(MyActivity.this);
group.addView(firstEdit);


final TextView second= new TextView(MyActivity.this);
second.setText("Second");
group.addView(second);
final EditText secondEdit= new EditText(MyActivity.this);
group.addView(secondEdit);

final TextView third= new TextView(MyActivity.this);
third.setText("Third");
group.addView(third);
final EditText thirdEdit= new EditText(MyActivity.this);
group.addView(thirdEdit);

final TextView fourth= new TextView(MyActivity.this);
fourth.setText("Fourth");
group.addView(fourth);
final EditText fourthEdit= new EditText(MyActivity.this);
group.addView(fourthEdit);

alert.setView(group);

你是如何添加 ScrollView 的，它对我有用。你是为什么平台开发的？您是否有限制对话框高度的主题/样式集？

    ...
    EditText fourthEdit= new EditText(MyActivity.this);
    group.addView(fourthEdit);

    ScrollView scrollView = new ScrollView(MyActivity.this);
    scrollView.addView(group);
    alert.setView(scrollView);
    alert.show();
}
