将背景Drawable设置为TextView导致java.lang.StackOverflowError

Question

我想在一个TextView的背景上添加一些涟漪效果，并在其中使用一张png图片，查阅了这篇文章

我的action_darwer.xml drawable如下：

<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>

将其设置为TextView，如下所示：

<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"/>

它完全无法工作并显示错误。

展示drawable/drawer的代码，还是一张图片？ - Vladyslav Matviienko

@VladMatvienko 是的，确切地说那是一张图片！ - Arshad Ali

你确定吗？你能发布一下你的资源文件夹结构的截图吗？ - Vladyslav Matviienko

Answer 1

StackOverflowError是由于应用程序递归过深而发生的。

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>

欲了解更多详情，请查看如何在使用时修改涟漪颜色？

我需要在背景中实现涟漪效果，因此请提供相关的drawable.xml文件，如pressed状态。 - Arshad Ali

@ArshadAli 附加信息，drawable不以尺寸/分辨率为导向的高容量资源。 - IntelliJ Amiya

Answer 2

就我所知，你不能将?attr/selectableItemBackgroundBorderless定义为drawable，这就是崩溃的原因。将其更改为其他drawable。

例如：

<?xml version="1.0" encoding="utf-8"?><selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/pressed" android:state_pressed="true" /> <!-- pressed -->
    <item android:drawable="@drawable/drawer" /> <!-- default -->
</selector>
