Android Spinner没有使用Android 5.0的三星设备

我正在使用自定义Spinner小部件，其代码如下。 除了三星的Android 5.0设备外，大多数设备都能正常运行。 单击时，微调器应显示值列表但不会发生。

在使用Android 5.0的模拟器和其他品牌设备上，它可以正常工作。

有没有人遇到类似的问题或者对可能发生的事情有任何想法？

XML

Java的

微调

示例结果

提前致谢。

Answer 1

我终于修好了！

android属性clickable设置为false ，但是在以下代码的ComboBoxView.java文件中执行了单击行为：

 private final OnClickListener onClick = new OnClickListener() { @Override public void onClick(View v) { mSpinner.performClick(); } }; 

除了在安装了Android 5.0的三星设备上之外，它在各处工作（设备和模拟器）。 我无法弄清楚为什么。

在我将cliclabke属性更改为true后，它开始工作。

 android:clickable="true" 

谢谢。
