如何使用 LinearLayout 增加单选按钮的大小 [英] How to increase radio button size using LinearLayout

问题描述

我正在尝试增加 LinearLayout 中 RadioButton 的大小，它包装到 ScrollView 中，但它没有以任何方式工作.我尝试使用 .setScaleX() 和 .setScaleY() 之类的属性，但没有用.这是我的代码:

I am trying to increase the size of RadioButton in LinearLayout which wraps into ScrollView but it is not working in any way. I tried to use property like .setScaleX() and .setScaleY() but it didn't work. Here is my code:

layout.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:orientation="vertical"
              android:layout_width="match_parent"
              android:layout_height="match_parent" android:weightSum="1">



    <LinearLayout
            android:paddingTop="10dp"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:paddingBottom="10dp"
            android:orientation="horizontal">
        <TextView
                android:text="Current location: "
                android:textSize="16sp"
                android:textStyle="bold"
                android:paddingRight="5sp"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"/>
        <TextView
                android:id="@+id/current_location"
                android:textSize="16sp"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"/>
    </LinearLayout>


    <ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
                android:layout_width="match_parent"
                android:sca
                android:layout_height="match_parent">

    <LinearLayout
            android:id="@+id/zone_types_list_View"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:choiceMode="singleChoice"
            android:orientation="vertical"
            android:background="@drawable/room_type_border"/>
    </ScrollView>

</LinearLayout>

使用 radioGroup 创建单选按钮的代码:

private LinearLayout listView;
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
  listView = (LinearLayout) rootView.findViewById(R.id.zone_types_list_View);
}

private void addRadioButtons() {
        if (getActivity() != null) {
            getActivity().runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    radioGroup = new RadioGroup(mActivity);
                    for (String ss : typesList) {
                        radioButton = new RadioButton(mActivity);
                        radioButton.setText(ss);
                        radioButton.setTag(ss.trim());
                        radioGroup.addView(radioButton);
                        radioButton.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
                            @Override
                            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                                if (isChecked) {
                                    String tag = (String) buttonView.getTag();
                                    Log.i(TAG, "selected radio: " + tag);
                                    submitZoneType(tag.trim());
                                }
                            }
                        });
                    }
               /*     radioGroup.setPivotX(0);
                    radioGroup.setPivotY(0);

                    radioGroup.setScaleX(2f);
                    radioGroup.setScaleY(2f); */
                    listView.addView(radioGroup);
                }
            });
        }
    }

如果我动态添加 radioGroup.setScaleX(2f)，它会帮助我增加 RadioButton 的大小，然后增加 buttons 的其余部分隐藏在 layout 中并且滚动不起作用.我不明白为什么滚动不能像这样工作.有没有其他方法可以增加 RadioButtons 的大小?

If I add radioGroup.setScaleX(2f) dynamically, it helps me to increase the RadioButtons size but then rest of the buttons hide in the layout and scrolling not work. I am not understanding why scrolling is not working like this way. Is there any other way to increase the size of RadioButtons?

推荐答案

有效

radioButton.setHeight(10);
radioButton.setWidth(5);
