我有一个有fragment
和image button
的应用。问题是它在5.0
之上和之上工作但不低于5.0。 min sdk版本是17.
这里没有弄错。我有两个例外。
RuntimeException
为image button
。
对于fab选择器文件,第二个是ResourceNotFoundException
。
日志: 第一个例外 -
java.lang.RuntimeException:无法启动活动 ComponentInfo {com.example.siddhi.timetablelayout / com.example.siddhi.timetablelayout.MainActivity}: android.view.InflateException:二进制XML文件行#16:
错误提升课程ImageButton
第二个例外 -
引起:android.view.InflateException:二进制XML文件行#16: 扩展类ImageButton
时出错

此例外

得出的结论是<solid android:color="?attr/colorAccent" />
中的这一行fab_selector
是罪魁祸首。尝试将color
更改为HEX value
,然后进行测试。
希望这会有所帮助。

答案 3 :(得分:0)
image.png的格式不正确。 我的解决方案: 我在PC上安装了greenshot以从屏幕上捕获图像 https://getgreenshot.org/ 然后,我在res / drawable中将图像另存为png文件。 这对我有用
答案 4 :(得分:0)
我也遇到了这个问题,但是我解决了。
在我的情况下,错误是我为ImageButton导入的png图像由android studio自动保存在drawable-v24中。我从那里复制了png并将其粘贴到可绘制的文件夹中。
