如何在Android中使行扩展为表的全宽

我遵循了上的示例，但不幸的是，该行没有扩展到表的整个宽度（请参见右侧的黑色“border”/“background”如何如此之大，而其他地方的宽度仅为1px）

我希望第二列扩展，因此它将占用右侧所有可用空间

这是我正在使用的代码。请告诉我，如果有人知道我怎样才能把正确的“边界”设置为1px，而不是看起来那么糟糕，请告诉我

        for (int i = 0; i < tasks.size(); i++)
    {
        TaskDetail taskDetail = tasks.get(i);

        TableRow row = new TableRow(this);

        // Set the background/border colour to black
        row.setBackgroundColor(Color.BLACK);
        row.setPadding(1, 1, 1, 1);

        TableRow.LayoutParams layoutParams = new TableRow.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);

        layoutParams.setMargins(0,0,1,0);

        LinearLayout detailCell = new LinearLayout(this);
        detailCell.setBackgroundColor(Color.parseColor("#FFE6F0"));
        detailCell.setLayoutParams(layoutParams);

        LinearLayout valueCell = new LinearLayout(this);
        valueCell.setBackgroundColor(Color.WHITE);
        valueCell.setLayoutParams(layoutParams);    

        TextView detailName = new TextView(this);
        detailName.setTextSize(TypedValue.COMPLEX_UNIT_SP, 18);
        detailName.setText(taskDetail.getName());
        detailName.setPadding(5, 10, 5, 5);
        detailName.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));

        TextView valueName = new TextView(this);
        valueName.setTextSize(TypedValue.COMPLEX_UNIT_SP, 18);
        valueName.setText(taskDetail.getValue());
        valueName.setPadding(5, 10, 5, 5);
        valueName.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));

        detailCell.addView(detailName);
        valueCell.addView(valueName);

        // Add to the screen layout
        row.addView(detailCell);
        row.addView(valueCell);

        table.addView(row);
    }

for（int i=0；i

将行中每列的

权重设置为
1.0f
，如下所示：

TableRow.LayoutParams layoutParams = new TableRow.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT, 1.0f);

...
...

row.setPadding(1, 1, 1, 1);

TableRow.LayoutParams layoutParams = new TableRow.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT, 1.0f);
layoutParams.setMargins(0,0,1,0);

LinearLayout detailCell = new LinearLayout(this);

...
...

只需进行如下更改：

TableRow.LayoutParams layoutParams = new TableRow.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT, 1.0f);

...
...

row.setPadding(1, 1, 1, 1);

TableRow.LayoutParams layoutParams = new TableRow.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT, 1.0f);
layoutParams.setMargins(0,0,1,0);

LinearLayout detailCell = new LinearLayout(this);

...
...

请遵循此链接：如果其他人好奇，我发现的另一种方法是添加detailName.setWidth（0）；和valueName.setWidth（0）；以及table.SetStretCharlColumns（true）；通过这样做，您可以通过编程设置表布局，使列具有相等的宽度。
