如何使动态生成的表格布局可滚动？

Question

我在 Activity 中有 3 个片段，在其中两个片段中我在 a 中有硬编码TableLayout，ConstraintLayout表的标题和行是使用来自 MySQL 服务器的信息动态生成的。鉴于其动态特性，表格能够溢出页面，我希望它可以滚动。

StackOverflow 上已经有多个问题，人们想要一个可滚动的表格，但在这些问题中，表格及其数据是硬编码的（不知道这是否相关）。我已经尝试了这些问题中提出的解决方案，但它们在我的桌子上不起作用。解决方案通常是将TableLayouta包装起来ScrollView或使用这两种方法android:isScrollContainer="1"都不适合我。

TableLayout里面ScrollView。用于测试，ScrollView通常它只是TableLayout.

<?xml version="1.0" encoding="utf-8"?>

<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"

    xmlns:app="http://schemas.android.com/apk/res-auto"

    xmlns:tools="http://schemas.android.com/tools"

    android:layout_width="match_parent"

    android:layout_height="match_parent"

    tools:context=".ViewProductLocFragment">

    <!-- Rest of the fragment -->

    <ScrollView

        android:layout_width="0dp"

        android:layout_height="0dp"

        android:layout_marginStart="8dp"

        android:layout_marginTop="16dp"

        android:layout_marginEnd="8dp"

        android:layout_marginBottom="16dp"

        android:layout_weight="1"

        android:scrollbars="none"

        app:layout_constraintBottom_toTopOf="@+id/menuBar"

        app:layout_constraintEnd_toEndOf="parent"

        app:layout_constraintStart_toStartOf="parent"

        app:layout_constraintTop_toBottomOf="@+id/view">

        <TableLayout

            android:id="@+id/tableLayout"

            android:layout_width="match_parent"

            android:layout_height="wrap_content"

            android:layout_marginStart="5dp"

            android:layout_marginTop="5dp"

            android:layout_marginEnd="5dp"

            android:layout_marginBottom="5dp"

            android:stretchColumns="*"

            app:layout_constraintBottom_toTopOf="@+id/menuBar"

            app:layout_constraintEnd_toEndOf="parent"

            app:layout_constraintStart_toStartOf="parent"

            app:layout_constraintTop_toBottomOf="@+id/view">

        </TableLayout>

    </ScrollView>

</android.support.constraint.ConstraintLayout>

Answer 1

您可以使用TableView 库使您的表格可滚动使用动态数据。链接如下：-https://github.com/evrencoskun/TableView

我已经尝试通过 Activity 实现您的代码。我发布了我的 Activity 和 XML 代码供您参考，您能否查看完整代码中缺少的内容，以便提供帮助。MainActivity.javapublic class MainActivity extends Activity {TableLayout tableLayout;@Overrideprotected void onCreate(Bundle savedInstanceState) {&nbsp; &nbsp; super.onCreate(savedInstanceState);&nbsp; &nbsp; setContentView(R.layout.activity_main);&nbsp; &nbsp; initializeTableLayout();}@Overrideprotected void onResume() {&nbsp; &nbsp; super.onResume();&nbsp; &nbsp; fillTable();}private void fillTable() {&nbsp; &nbsp; Integer count = 0;&nbsp; &nbsp; for (int i = 0; i < 100; i++) {&nbsp; &nbsp; &nbsp; &nbsp; String barcode = "#0000000000";&nbsp; &nbsp; &nbsp; &nbsp; String location = "Location";&nbsp; &nbsp; &nbsp; &nbsp; Integer quantity = 1;&nbsp; &nbsp; &nbsp; &nbsp; TableRow tableRow = new TableRow(MainActivity.this);&nbsp; &nbsp; &nbsp; &nbsp; if (count % 2 != 0) {&nbsp;
