如何设置 table 的小标题行的宽度？

Question

TableLayout tl = new TableLayout(ActivityAddFlashcard.this);
        TableRow tittleRow = new TableRow(ActivityAddFlashcard.this);
        TableRow fRow = new TableRow(ActivityAddFlashcard.this);
        TableRow.LayoutParams params = new TableRow.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT
                , LinearLayout.LayoutParams.WRAP_CONTENT);
        fRow.addView(getTextView("کلمه"));
        fRow.addView(getTextView("معنی"));
        TextView tv = new TextView(ActivityAddFlashcard.this);
        tv.setLayoutParams(new TableRow.LayoutParams(tl.getWidth() // <---- //return 0 
                , TableRow.LayoutParams.WRAP_CONTENT));
        tv.setText("dksvlfsnfmmmmnv");
        tittleRow.addView(tv);
        tittleRow.setGravity(Gravity.CENTER);
        tl.addView(tittleRow);

        fRow.addView(new TextView(ActivityAddFlashcard.this));
        tl.addView(fRow);
        TableLayout.LayoutParams params2 = new TableLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT
                , LinearLayout.LayoutParams.WRAP_CONTENT);

        fRow.setGravity(Gravity.CENTER);
        fRow.setLayoutParams(params);
        tl.setLayoutParams(params2);
        tl.setGravity(Gravity.CENTER);

这是我的 table 布局，我想将标题行的宽度设置为等于 table 的宽度。但是 getWidth return 0 .

您的视图可以在布局过程中不时更改其宽度。可能您正在寻找 MATCH_PARENT 解决方案：

tv.setLayoutParams(
    new TableRow.LayoutParams(
        TableRow.LayoutParams.MATCH_PARENT, 
        TableRow.LayoutParams.WRAP_CONTENT
    )
);

您可能也有兴趣将 MATCH_PARENT 设置为 tittleRow 的 layoutParameter。
