ScrollView 레이아웃이 전체 화면을 채우지 않습니다.


나는 Activity두 개의 Fragments (하나의 목록 하나의 정상)를 얻었습니다 . 정상 Fragment이 팽창 Scrollview함유 LineaLayout(수직)이 레이아웃을 포함 TextViews. ScrollViewlayout_widthlayout_height있습니다 match_parent내가 생각하는, 그래서 전체 화면이 사용되어야한다. 그러나 바닥에는 여전히 "간격"이 있습니다. 당신이 나를 도울 수 있기를 바랍니다.

ScrollView.xml

<ScrollView
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/scrollView1"
android:layout_width="match_parent"
android:layout_height="match_parent">

<LinearLayout
    android:id="@+id/LinearLayout1"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/titlescreen_bg"
    android:orientation="vertical"
    android:paddingTop="60dp"
    tools:context=".MainActivity" >

    <TextView
        android:id="@+id/tv_headline"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:paddingBottom="60dp"
        android:paddingTop="60dp"
        android:textIsSelectable="false"
        android:textSize="@dimen/fontsize_slogan_titlescreen" />

    <TextView
        android:id="@+id/tv_content"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:gravity="center"
        android:paddingBottom="30dp"
        android:paddingTop="30dp"
        android:textIsSelectable="false"
        android:textSize="@dimen/fontsize_slogan_titlescreen" />
</LinearLayout>

</ScrollView>

감사합니다.

편집 : 문제가 이미 해결되었습니다 : android : fillViewPort = "true", 문제를 보여 드리고 싶습니다.

그러나 나는 사진을 올릴만큼 충분한 평판이 없다. 죄송합니다!


If i'm not mistaken, the ViewGroup's height (LinearLayout's height in your case), that is the (only) child inside a ScrollView, is always interpreted as wrap_content, since that content can be larger than the ScrollView's height (hence the scrollbars).

This also means that if the content is smaller, the ScrollView's content (child) may not necessarily stretch to fill the screen.

In order to visually help you fix this, we need to see a screenshot of your problem.

Maybe setting android:fillViewport="true" on the ScrollView will fix your issue:

<ScrollView
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/scrollView1"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fillViewport="true">

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:fillViewport="true"
    android:fadeScrollbars="false"
    android:scrollbars="vertical" >

In your ScrollView add an attribute ie.

android:fillViewport="true"

inflater.inflate(R.layout.menu_content_main, container);

should be

inflater.inflate(R.layout.menu_content_main, container, false);

I had a similar problem and could only fix it with a Helper Class. I found the original code online and this is my implementation of it.

Java class:

public class ImageViewHelper extends android.support.v7.widget.AppCompatImageView {

    public ImageViewHelper(Context context) {
        super(context);
    }

    public ImageViewHelper(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public ImageViewHelper(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        Drawable d = getDrawable();
        if (d != null) {
            int w = MeasureSpec.getSize(widthMeasureSpec);
            int h = w * d.getIntrinsicHeight() / d.getIntrinsicWidth();
            setMeasuredDimension(w, h);
        }
        else super.onMeasure(widthMeasureSpec, heightMeasureSpec);
    }
}

XML:

<com.example.app.ImageViewHelper
    android:id="@+id/img"
    android:src="@drawable/start"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentTop="true"
    android:layout_centerHorizontal="true"
    android:adjustViewBounds="true" />
