滚动视图无法正常使用填充

Question

I have a problem in my Activity . The ScrollView doesn't scroll down to the bottom. Here's my XML layout of the ScrollView :

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:background="@drawable/test"
            android:paddingRight="@dimen/layoutsPadding"
            android:paddingTop="@dimen/layoutsPadding"
            android:paddingLeft="@dimen/layoutsPadding"
            android:paddingBottom="@dimen/scrollViewLayoutsPadding">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@color/tab_introduction_background"
        android:orientation="vertical"
        android:padding="@dimen/layoutsPadding">

        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="@string/tab_introduction_title"
            android:textSize="@dimen/bigFont"></TextView>

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="@dimen/gap_titleAndText">
        </LinearLayout>

        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="@string/tab_introduction_description"
            android:textSize="@dimen/smallFont"></TextView>
    </LinearLayout>

</ScrollView>

What Can I do?

Answer 1

Since removing LinearLayout 's padding worked, but you want it to have padding, why not just surround it with another LinearLayout and let only this outer LinearLayout to have a padding. And remove the inner LinearLayout 's padding. This is probably not a very good style, but worth a try.

If you want to avoid this, you can also try removing the padding from the LinearLayout and adding a margin to all it's children.

EDIT: Since you really need that padding, adding an empty view at the bottom will definitely solve your problem, but it's not a good solution either:

<View
android:layout_width="fill_parent"
android:layout_height="30dp" />
