以编程方式在RelativeLayout中设置边距tooglebutton

Question

我在ToggleButton动态创建GridView。我可以显示我从服务器发送的所有ToggleButton。唯一的问题是我无法设置任何余量来将ToggleButton分开。我是以编程方式添加ToggleButton的。

我需要使用gridlayout。

如何以编程方式在ToggleButton之间设置边距。

类别：

  for (int i = 0; i < arrayList.size(); i++) {
            final ToggleButton toogleBtn = new ToggleButton (RegisterThreeActivityNew.this);
            toogleBtn.setPadding(50,10,30,20);
            toogleBtn.setWidth(140);
            toogleBtn.setHeight(20);
            toogleBtn.setTextSize(12);
            toogleBtn.setText(arrayList.get(i).getName());
            toogleBtn.setTextOff(arrayList.get(i).getName());
            toogleBtn.setTextOn(arrayList.get(i).getName());
            toogleBtn.setTextColor(ResourcesCompat.getColor(getResources(), R.color.white, null));
            toogleBtn.setBackground(ResourcesCompat.getDrawable(getResources(), R.drawable.btn_category, null));

            final long id = arrayList.get(i).getId();
            toogleBtn.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
                public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                    if (isChecked) {
                        toggleEnabled(toogleBtn);
                        categories.add(id);
                    } else {
                        toggleDissabled(toogleBtn);
                        categories.remove(id);
                    }
                }
            });
            gridLayout.addView(toogleBtn);
        }
