android - 将 background drawable 设置为 TextView 导致 java.lang.StackOverflowError

Question

我想在 TextView 的背景中使用 png 图像添加一些波纹效果，发现 this Post

我有 action_darwer.xml 可绘制为

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="?attr/selectableItemBackgroundBorderless" android:state_pressed="true" /> <!-- pressed -->
    <item android:drawable="@drawable/drawer" /> <!-- default -->
</selector>

并将其设置为 TextView 为

<TextView android:id="@+id/action_drawer"
    android:layout_marginLeft="20dp"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@drawable/action_drawer"/>

它根本不工作并给出错误

如何解决这个问题？任何建议将不胜感激。谢谢。

Answer 1

StackOverflowError occurs because an application recurses too deeply.

首先修改background

<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:state_pressed="true"
      android:drawable="@drawable/pressed/>  // Press State
<item android:state_focused="true"
      android:drawable="@drawable/focused"/> // Focused
<item android:drawable="@drawable/drawer"/>  // Default State

</selector>
