使用动画更改RadioButtons的权重
使用动画更改RadioButtons的权重
提问于 2020-04-08 17:10:03
我有下面的代码。我想在用户单击此按钮时更改单选按钮的权重。我的意思是，当用户选择一个单选按钮时，将其权重更改为2，而未选中的单选按钮的权重更改为1，反之亦然。(单选按钮组的权重和为3)。当我选择左侧单选按钮时，首先更改大小，然后更改颜色。我希望当用户选择左单选按钮时，它会从左向右按下，而不是突然改变大小。
XML代码：
<RadioGroup
android:checkedButton="@+id/onTimeRadioButton"
android:id="@+id/checkToggle"
android:layout_marginTop="15dp"
android:layout_width="match_parent"
android:layout_height="30dp"
android:layout_marginLeft="50dp"
android:layout_marginRight="50dp"
android:background="@drawable/rb_drawable"
android:orientation="horizontal"
android:weightSum="3">
<RadioButton
android:layout_marginTop="1dp"
android:layout_marginBottom="1dp"
android:layout_marginLeft="1dp"
android:id="@+id/groupRadioButton"
android:background="@drawable/toggle_widget_background"
android:layout_width="0dp"
android:layout_height="match_parent"
android:onClick="onRadioBttonClicked"
android:layout_weight="1"
android:button="@null"
android:gravity="center"
android:text="groupCheck"
android:textSize="15sp"
android:textAlignment="center"
android:textColor="@android:color/white" />
<RadioButton

</RadioGroup>Java代码：

我建议在LinearLayout.LayoutParams中程序化地改变权重，在那之前添加一行：
TransitionManager.beginDelayedTransition(yourRootLinearLayout, new ChangeBounds());页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
