Question

在底部带有editText的LinearLayout覆盖了scrollView的内容，该内容以编程方式填充。怎么避免这个？我在这个消息的第一个版本中简化了XML。我现在已经添加了完整的代码

我想保持我的editText高度可扩展。

有什么想法吗？谢谢！

Answer 1

我建议使用相对布局作为父级。然后添加上面的规则。

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">

<ScrollView
    android:id="@+id/scroll"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:layout_above="@+id/llButton"
    android:orientation="vertical">

    <LinearLayout
        android:id="@+id/linear"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">

    </LinearLayout>
</ScrollView>

<LinearLayout
    android:id="@+id/llButton"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:orientation="horizontal">

    <EditText
        android:id="@+id/editMessage"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="center_vertical|center_horizontal"

        android:gravity="top|left"
        android:inputType="textMultiLine|textCapSentences"
        android:maxLines="5"
        android:minLines="3"
        android:scrollHorizontally="false" />

    <Button
        android:id="@+id/buttonSend"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_vertical|center_horizontal"
        android:gravity="center"
        android:text='send'
        android:textAppearance="?android:attr/textAppearanceMedium" />
</LinearLayout>

        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical" >

        <LinearLayout

                    android:background="@drawable/edit"
                    android:gravity="top|left"
                    android:inputType="textMultiLine|textCapSentences"

                    android:scrollHorizontally="false"
                     />

                <Button
                    android:id="@+id/buttonSend"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:layout_gravity="center_vertical|center_horizontal"
                    android:background="@drawable/button_normal"
                    android:gravity="center"
                    android:text="send"
                    android:textAppearance="?android:attr/textAppearanceMedium" />
            </LinearLayout>
        </LinearLayout>


</ScrollView>
