android - 动画切换按钮错误膨胀类 android.widget.ToggleButton

Question

我试图制作一个带有动画的切换按钮，我使用一个切换按钮和 4 个 XML 来实现:这是我的主要 Activity ，其中包含切换按钮:

<ToggleButton
    android:id="@+id/toggle"
    android:layout_width="144dp"
    android:layout_height="144dp"
    android:layout_centerHorizontal="true"
    android:layout_centerVertical="true"
    android:background="@drawable/btn_toggle_bg"
    android:checked="true"
    android:onClick="OnPressToggle" />

这是我的 btn_toggle_bg 。具有背景值的 xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@+android:id/background" android:drawable="@android:color/transparent" />
<item android:id="@+android:id/toggle" android:drawable="@drawable/btn_toggle" />
</layer-list>
</LinearLayout>

这是我的 btn_toggle 。 XML:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_checked="true"  android:drawable="@drawable/btn_switch_on" />
<item android:state_checked="false"  android:drawable="@drawable/btn_switch_off" />
</selector>

这是新的日志猫

Answer 1

您的绘图名称不能以数字开头:

将它们全部重命名为，例如:

<item android:drawable="@drawable/d1" android:duration="50"/>
<item android:drawable="@drawable/d2" android:duration="50"/>
...

以下是您应该遵循的命名规则:

• 需要以字母而非数字开头
• 不能包含大写字母
• 不能包含字母和数字以外的任何内容
