                />
        </android.support.design.widget.TextInputLayout>
    </LinearLayout>
</ScrollView>

最后一个可见控件是“状态”。我试图 PadBottom="20dp" 然后我用 RelativeLayout 包装 ScrollView 但仍然有同样的问题。

最低 SDK API 23 Android 6

非常感谢任何帮助。谢谢

标签： android fragment scrollview

【解决方案1】：

在不同的 xml 文件中定义片段的内容，然后将其包含在片段 xml 文件中，并改用 NestedScrollView

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:tools="http://schemas.android.com/tools"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  tools:context="com.example.ibrahimnehme.slidingtab.StockTakeFragment">

  <android.support.v4.widget.NestedScrollView
      android:layout_width="match_parent"
      android:layout_height="match_parent">

   <include layout="@layout/yourOtherXMLFile"/>

  </android.support.v4.widget.NestedScrollView>
</FrameLayout>

【解决方案2】：

您删除了 android.support.design.widget.TextInputLayout 中的填充

<android.support.design.widget.TextInputLayout
            android:layout_width="match_parent"
            android:paddingBottom="20dp"
            android:layout_height="wrap_content">

            <AutoCompleteTextView
                android:id="@+id/Serial_Number"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:hint="Serial Number"
                android:inputType="text"
                android:maxLines="1"
                />

删除 android:paddingBottom="20dp"

【讨论】：

添加 android:marginBottom="20dp" 对你有帮助

添加android:fillViewPort="true" 所以

                <AutoCompleteTextView
                    android:id="@+id/Serial_Number"
                    android:layout_width="match_parent"

                    />
            </android.support.design.widget.TextInputLayout>
        </LinearLayout>
    </ScrollView>

我遇到了同样的问题。添加fillViewPort 使滚动视图填充其视图。
