以编程方式将 TextView 添加到网格布局对齐方式不正确

Question

您好我正在尝试将带有 drawableLeft 的 TextView 添加到 GridLayout。我在一个循环中添加这个 TextView。 TextView 已正确添加，但未正确对齐。每个 textview 应该在一个水平行中采用相等的宽度，但这并没有发生。

以下是我正在使用的代码

    GridLayout gridLayout = new GridLayout(getContext());
            gridLayout.setAlignmentMode(GridLayout.ALIGN_BOUNDS);
            gridLayout.setColumnCount(2);
            gridLayout.setRowCount(3);
            TextView titleText;
            for (int i = 0; facilities != null && i < facilities.size(); i++) {
                titleText = new TextView(getContext());
                titleText.setText(facilities.get(i));
                gridLayout.addView(titleText, i);
                titleText.setCompoundDrawablesWithIntrinsicBounds(rightIc, 0, 0, 0);
}

为此，您必须动态设置视图的列宽。这最终将使每个视图与等量空间正确对齐。

 GridLayout gridLayout = new GridLayout(getContext());
            gridLayout.setAlignmentMode(GridLayout.ALIGN_BOUNDS);
            gridLayout.setColumnCount(2);
            gridLayout.setRowCount(3);
            TextView titleText;
            for (int i = 0; facilities != null && i < facilities.size(); i++) {
                titleText = new TextView(getContext());
                titleText.setText(facilities.get(i));
                gridLayout.addView(titleText, i);
                titleText.setCompoundDrawablesWithIntrinsicBounds(rightIc, 0, 0, 0);
                GridLayout.LayoutParams param =new GridLayout.LayoutParams();
                param.height = LayoutParams.WRAP_CONTENT;
                param.width = LayoutParams.WRAP_CONTENT;
                param.rightMargin = 5;
                param.topMargin = 5;
                param.setGravity(Gravity.CENTER);
                param.columnSpec = GridLayout.spec(c);
                param.rowSpec = GridLayout.spec(r);
                titleText.setLayoutParams (param);

}
