Java.lang.StackOverflowError由setImageResource引起。

Question

我的 Android 应用在初始化 TabHost 时崩溃了。但是，从用户的崩溃日志来看，这种崩溃情况非常奇怪！

大部分崩溃都出现在 Android 2.3.x 上，在 Android 4.x 上它能正常工作。

我可以看到当我调用 "setImageResource" 时，代码进入了无限递归，但我不明白为什么。

代码：

View tabIndicator = LayoutInflater.from(this).inflate(R.layout.tab_indicator, getTabWidget(), false); ImageView icon = (ImageView) tabIndicator.findViewById(R.id.icon); icon.setImageResource(drawableId); // 崩溃了

你是指从状态列表可绘制对象内部引用相同的状态列表吗？ - wsanville

请展示被 drawableId 引用的 XML 文件。 - Henry

Answer 1

这是由于执行无限循环引起的。这可能是由于在用作图标的可绘制对象中存在循环调用所致。具有指定drawableId的Drawable可能会调用第二个Drawable，而第二个Drawable又会调用第一个Drawable。

提供有关您使用的Drawable的更多详细信息可能有助于提供更好的答案。

事实上，我定义了一个选择器drawable，其中引用了一个图像drawable资源。不小心它们有相同的名称，没有编译错误，但在Android 4.0中确实有效。在Android 2.3中会崩溃。无论如何，非常感谢！ - ThankCreate
