Question

就像标题所说，我在将TableViews均匀地传播到tableRows时遇到了问题。我的xml是：

   <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal">
  <ProgressBar/>
  <TextView/>

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/scrollView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_below="@+id/progressBar">

    <TableLayout
        android:id="@+id/tableLayout"
        android:layout_width="match_parent"
        android:layout_height="match_parent">
       </TableLayout>

</ScrollView>

在Activity启动后，将使用以下代码创建动态表：

     for (int i = 0; i < 4; i++) {
      tableRow = new TableRow(this);
      tableRow.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,
              ViewGroup.LayoutParams.WRAP_CONTENT));

      tableRow.setId(i + 1);
      tableRow.setBackgroundResource(R.mipmap.shelfboard);
      tableRow.setPadding(20, 0, 20, 0);
      tableRow.setOnClickListener(thisvariable);

      tableLayout.addView(tableRow);
  }

现在我想为每个tableRow为每个tableRow添加不同数量的相同宽度的ImageView。

我有4个TableRows

将2个ImageView添加到tableRow 1
将5个ImageView添加到tableRow 2
将3个ImageView添加到tableRow 3
将7个ImageView添加到tableRow 4

我的代码是：

    for (int i = 0; i < adpList.size(); i++) {
            int row = adpList.get(i).getShelfBoard();
            if (row==1) {
                int productsPerBoard = 2;
                int width = (tableLayout.getWidth()) / productsPerBoard;

                TableRow.LayoutParams tlp = new TableRow.LayoutParams(width, TableRow.LayoutParams.MATCH_PARENT);

                productPicture = new ImageView(this);
                r = (TableRow) findViewById(row);
                productPicture.setLayoutParams(tlp);
            }
            if (row==2) {
                int productsPerBoard = 5;
                int width = (tableLayout.getWidth()) / productsPerBoard;


                TableRow.LayoutParams tlp = new TableRow.LayoutParams(width, TableRow.LayoutParams.MATCH_PARENT);
                productPicture = new ImageView(this);
                productPicture.setBackgroundResource(R.drawable.border);
                r = (TableRow) findViewById(row);

                productPicture.setLayoutParams(tlp);
            }
            if (row==3) {
                int productsPerBoard = 3;
                int width = (tableLayout.getWidth()) / productsPerBoard;
               TableRow.LayoutParams tlp = new TableRow.LayoutParams(width, TableRow.LayoutParams.MATCH_PARENT);

                productPicture = new ImageView(this);
                r = (TableRow) findViewById(row);
                productPicture.setLayoutParams(tlp);
            }
            if (row==4) {
                int productsPerBoard = 7;
                int width = tableLayout.getWidth() / productsPerBoard;

                TableRow.LayoutParams tlp = new TableRow.LayoutParams(width, TableRow.LayoutParams.MATCH_PARENT);

                productPicture = new ImageView(this);
                r = (TableRow) findViewById(row);
                productPicture.setLayoutParams(tlp);
            }
          productPicture.setBackgroundResource(R.mipmap.ic_launcher);
          r.addView(productPicture);

不幸的是，每行只有两张图片。它总是占用第一块板的宽度。我的输出：

如何为每行添加不同数量的ImageView？

Answer 1

我觉得太复杂了。更改LayoutParams解决了我的问题：

    r = (TableRow) findViewById(shelfboard);
    productPicture = new ImageView(this);

    TableRow.LayoutParams tlp = new TableRow.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,ViewGroup.LayoutParams.MATCH_PARENT, 1f);
    tlp.setMargins(0, 20, 0, 50);
    productPicture.setLayoutParams(tlp);

将imageViews均匀地传播到tablerow上
