Android 动态生成 radiobutton 解决 radiogroup 多行显示的问题 单选

项目有需求，然后看了下网上的方法，好多都太麻烦了，而且也不怎么靠谱。。

先上效果图



先上布局的代码

<RadioGroup
android:id="@+id/radio_group_directory_filter_game"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:weightSum="3"
android:layout_below="@id/text_title_game"/>

然后是java代码

public void setGameRadioButton(RadioGroup gameRadioGroup){
Gson gson = new Gson();
List<Group> allGroups = new ArrayList<>();
allGroups.add(new Group("Dota2","Dota2"));
allGroups.add(new Group("LOL","LOL"));
allGroups.add(new Group("守望先锋","守望先锋"));
allGroups.add(new Group("王者荣耀","王者荣耀"));
float density = getResources().getDisplayMetrics().density;
RadioGroup.LayoutParams radioParams = new RadioGroup.LayoutParams(0, ViewGroup.LayoutParams.WRAP_CONTENT, 1.0f);
int radioMargin = (int) (4 * density);
radioParams.setMargins(0, radioMargin, 16, radioMargin);
int i = 0;
while (i < allGroups.size()) {
int j = 0;
LinearLayout ll = new LinearLayout(getActivity());
ll.setOrientation(LinearLayout.HORIZONTAL);
ll.setLayoutParams(new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT));
ll.setWeightSum(3.0f);
while (j < 3 && i < allGroups.size()) {
ll.addView(getGameGroupRadio(allGroups.get(i),i), radioParams);
i++;
j++;
}
gameRadioGroup.addView(ll);
}

}

private RadioButton getGameGroupRadio(Group group,int position) {
RadioButton btn = (RadioButton) getActivity().getLayoutInflater().inflate(R.layout.radio_directory_sidebar, null);
btn.setText(group.getName());
switch (position){
case 0:
DOTA2_ID = btn;
break;
case 1:
LOL_ID = btn;
break;
case 2:
OVERWATCH_ID = btn;
break;
case 3:
KINGGLORY_ID = btn;
break;
}
btn.setOnClickListener(new View.OnClickListener() {//单独给每个生成的radiobutton生成点击事件，我是通过position来分辨不同radiobutto的，原因是，我通过对radiogroup再来监听radiobutton失败了，反正监听没反应，所以只能这么干了
@Override
public void onClick(View view) {
for (int i = 0; i < mRadioGame.getChildCount(); i++) {
LinearLayout row = (LinearLayout) mRadioGame.getChildAt(i);
for (int j = 0; j < row.getChildCount(); j++) {
RadioButton radio = (RadioButton) row.getChildAt(j);
radio.setChecked(false);
}
}
switch (position){
case 0:
DOTA2_ID.setChecked(true);
mDirectoryOption.setGameId(Game.DOTA2_ID);
break;
case 1:
LOL_ID.setChecked(true);
mDirectoryOption.setGameId(Game.LOL_ID);
break;
case 2:
OVERWATCH_ID.setChecked(true);
mDirectoryOption.setGameId(Game.OVERWATCH_ID);
break;
case 3:
KINGGLORY_ID.setChecked(true);
mDirectoryOption.setGameId(Game.KING_GLORY_ID);
break;
}
updateBar();
}
});
return btn;
}
