RadioGroup动态添加RadioButton

RadioGroup radioGroup = (RadioGroup) findViewById(R.id.radioGroup);

for (int i = 0; i < 10; i++) {
RadioButton radioButton = new RadioButton(this);
RadioGroup.LayoutParams lp = new RadioGroup.LayoutParams(RadioGroup.LayoutParams.WRAP_CONTENT, RadioGroup.LayoutParams.WRAP_CONTENT);
//设置RadioButton边距 (int left, int top, int right, int bottom)
lp.setMargins(SizeUtils.dp2px(10), SizeUtils.dp2px(10), SizeUtils.dp2px(10), SizeUtils.dp2px(10));
//设置RadioButton背景
radioButton.setBackgroundResource(R.drawable.radiobutton_background);
radioButton.setTextColor(getResources().getColorStateList(R.drawable.radiobutton_textcolor));
radioButton.setButtonDrawable(null);
//设置文字距离四周的距离
radioButton.setPadding(SizeUtils.dp2px(25), SizeUtils.dp2px(15), SizeUtils.dp2px(25), SizeUtils.dp2px(15));
radioButton.setTextSize(SizeUtils.sp2px(28));
radioButton.setId(i);
radioButton.setChecked(i == 0);
//设置文字
radioButton.setText(i + " #罐");
final int finalI = i;
//设置radioButton的点击事件
radioButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(TankWarningSettingActy.this, "this is radioButton " + finalI + " = " + v.getId(), Toast.LENGTH_SHORT).show();
}
});
//将radioButton添加到radioGroup中
radioGroup.addView(radioButton, lp);
