用Java代码自动添加按钮

 group =(RadioGroup)findViewById(R.id.r_r_radiogroup);

RadioButton radioButton = new RadioButton(this);
RadioGroup.LayoutParams layoutParams = new RadioGroup.LayoutParams(RadioGroup.LayoutParams.WRAP_CONTENT,50);
layoutParams.setMargins(10, 10, 10, 10);
radioButton.setLayoutParams(layoutParams);
radioButton.setText(“”+ii);
radioButton.setTextSize(12);
radioButton.setButtonDrawable(android.R.color.transparent);//隐藏单选圆形按钮
radioButton.setGravity(Gravity.CENTER);
radioButton.setPadding(10, 10, 10, 10);
radioButton.setBackground(getResources().getDrawable(R.drawable.selector_white_graydark_checked));//设置按钮选中/未选中的背景
group.addView(radioButton);//将单选按钮添加到RadioGroup中
