Android Scroll View in layout-large-landscape 不滚动？

    </android.support.percent.PercentRelativeLayout>
</ScrollView>
    </LinearLayout>

Answer 1

这是因为caption_block 视图中缺少一个属性，它以某种方式弄乱了您的滚动视图。

<TextView
    android:id="@+id/caption_block"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:layout_below="@+id/visit_date"
    android:layout_toRightOf="@+id/caption_district"
    android:text="Block"
    android:textAppearance="?android:textAppearanceLarge"
    android:textColor="@android:color/black"
    android:textStyle="bold"
    app:layout_marginStartPercent="1%"
    app:layout_marginTopPercent="1%"
    app:layout_widthPercent="50%" />

将layout_height 属性设置为wrap_content，一切顺利。
