这个问题实际上与这篇文章有关.以编程方式设置TextView的布局权重

根据答案我只需要设置TextView布局参数如下并设置stretchColumn属性,但通过添加以下代码,它使textView从表格布局中消失.

TextView tv = new TextView(v.getContext());
tv.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, 1f));

所以,这是我的代码,我想动态添加一行3列,权重为35%,5%和60%.请告诉我我的代码有什么问题.

private void addTableRow(int resIdTitle, String strValue){

        TableRow tr = new TableRow(this);

        // Add First Column
        TextView tvTitle = new TextView(this);
        tvTitle.setText(resIdTitle);
        tvTitle.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, 
                LayoutParams.WRAP_CONTENT, 0.35f));
        tr.addView(tvTitle);

        // Add 2nd Column
        TextView tvColon = new TextView(this);
        tvColon.setText(" : ");
        tvColon.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, 
                LayoutParams.WRAP_CONTENT, 0.05f));
        tr.addView(tvColon);

        // Add the 3rd Column
        TextView tvValue = new TextView(this);
        tvValue.setText(strValue);
        tvValue.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, 
                LayoutParams.WRAP_CONTENT, 0.60f));
        tr.addView(tvValue);

        // Finally add it to the table
        tl.addView(tr, …
