Android的微调不工作的三星设备与Android 5.0

本文介绍了Android的微调不工作的三星设备与Android 5.0的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我使用的是自定义的微调部件与下面的code。 一切工作正常，除了三星的设备与Android 5.0的大多数设备。在单击微调应显示值的列表，但是这并没有发生。 在仿真器和其他品牌与Android 5.0设备的正常工作。

I'm using a custom Spinner widget with the code below. Everything works fine on most devices except on Samsung's devices with Android 5.0. On click the Spinner should display a list of values but that doesn't happen. On emulators and others brands devices with Android 5.0 it works fine.

有没有人遇到一个类似的ISSE或有可能发生的事任何想法？

Has anyone faced a similiar isse or have any idea of what might be happening?

推荐答案

我终于解决了这个问题！_爱 Android的属性点击设置为假，但在ComboBoxView.java文件以下执行的点击行为code：

I finally fixed this! The android property clickable was set to false, but the click behaviour was performed in the ComboBoxView.java file on the following code:

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

这是工作无处不在（设备和仿真器），除了在三星设备与Android 5.0。这个我想不出为什么。

This was working everywhere (devices and emulators) except on Samsung devices with Android 5.0. This I couldn't figure out why.

之后，我改变了 cliclabke 属性为true，它开始工作。

After I changed the cliclabke property to true it started working.

android:clickable="true"

谢谢你。

Thanks.
