Question

我已经知道之前已经提出过这个问题，但似乎没有一个解决方案适合我。

在srollView中我有一个表格布局，我在每行的最后一个单元格中添加三列我有一个大文本，应该在多行中自动格式化，但文本保持在屏幕外的一行。

问题是：当他到达屏幕末尾时，如何设置代码中的文本？

这是我的代码：

<?xml version="1.0" encoding="utf-8"?>
    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">

         <RelativeLayout
             android:id="@+id/buttons_up_system_storical_layout"
             android:layout_width="wrap_content"
             android:layout_height="wrap_content"
             android:layout_alignParentTop="true"
             android:gravity="left"
             android:orientation="horizontal" >

             <Button
                 android:id="@+id/btn_system_to_technical_part"
                 android:layout_width="wrap_content"
                 android:layout_height="wrap_content"
                 android:text="Parte tecnica" />

             <Button
                 android:id="@+id/btn_system_to_description"
                 android:layout_width="wrap_content"
                 android:layout_height="wrap_content"
                 android:layout_alignParentRight="true"
                 android:text="Descrizione" />

             <Button
                 android:id="@+id/btn_system_to_ticket"
                 android:layout_width="wrap_content"
                 android:layout_height="wrap_content"
                 android:layout_toLeftOf="@+id/btn_system_to_description"
                 android:layout_alignParentTop="true"
                 android:text="Vai a ticket" />

             <Button
                 android:id="@+id/btn_system_new_report"
                 android:layout_width="wrap_content"
                 android:layout_height="wrap_content"
                 android:layout_toRightOf="@+id/btn_system_to_technical_part"
                 android:text="Nuovo rapporto" />

         </RelativeLayout>

        <ScrollView 
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:id="@+id/scroll_view_system_description"
            android:layout_below="@+id/buttons_up_system_storical_layout" >

            <FrameLayout

                android:orientation="vertical"
                 >

                <TableLayout
                    android:layout_width="fill_parent"
                    android:layout_height="wrap_content"
                    android:stretchColumns="*"
                    android:id="@+id/tl_system_storical"
                    >

                </TableLayout>
            </FrameLayout>

        </ScrollView>

    </RelativeLayout>

Answer 1

为什么使用Button而不是TextView在屏幕上显示文字？默认情况下，文本视图是一个mutliline小部件，您无需执行任何操作即可使文本显示在多行中。

Answer 2

如果您坚持使用TableLayout，则可以将权重设置为上一个TextView：

TableRow.LayoutParams text3Params = new TableRow.LayoutParams();
text3Params.width = 0;
text3Params.weight = 1;
lblSystemStoricalDescription.setLayoutParams(text3Params);

但你也可以摆脱TableLayout并只使用一个容器，为每个当前行添加LinearLayouts，并将权重设置为所需的值。

的TextView＆＃39;文字保持在一行
