滚动型增加了顶部额外的空间 [英] ScrollView adds extra space on top

问题描述

我使用嵌套在一个滚动型内一个TextView。滚动工作正常，但滚动型似乎在看起来像这样TextView的顶部添加一个微胖：

I am using a TextView nested inside a ScrollView. Scrolling works fine, but the ScrollView seems to add an extra padding on the top of the TextView that looks like this:

<ScrollViewTop>
<Padding>
<TextViewTop>
<TextViewContent>
<TextViewBottom>
<ScrollViewBottom>

请注意，这仅发生在TextView的顶部并且该空间是静态的，滚动时不移动。这是我使用的是DialogFragment里面的布局：

Note that this only happens at the top of the TextView and that the space is static, does not move when scrolling. This is the layout I am using inside a DialogFragment:

<?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"
    android:fillViewport="true" 
    android:fadingEdge="none"
    android:orientation="vertical" >

        <TextView
        android:id="@+id/textViewHelp"
        android:adjustViewBounds="true"
        android:scrollbars = "vertical"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"/>
</ScrollView>

这是包含布局片段：

public class HelpDialogFragment extends DialogFragment {

    public interface HelpDialogFragmentListener {
        void onFinishHelpDialogFragment(String inputText);
    }

    //empty constructor for fragment (android requirement)
    public HelpDialogFragment() {

    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.help_fragment, container);
        TextView tv = (TextView) view.findViewById(R.id.textViewHelp);
        tv.setText(Html.fromHtml(Utils.loadHtmlFromResources(getActivity(), R.raw.help)));
        return view;
    }
}

我怎么能强迫的TextView占用整个滚动型区域？

How can I force the TextView to take up the entire ScrollView area?

问题是它可以通过设置去除窗口标题

The problem was the window title which can be removed by setting:

getWindow().requestFeature(Window.FEATURE_NO_TITLE);
