我开发使用4个标签的操作栏的应用程序。该应用程序将通过蓝牙发送消息到设备。我选择的代码部分更importants这里。
所以，第三个标签使用三个seekbars的配置将被发送的消息。第一个搜索条控制多少行的消息了。第二，搜索栏控制展，最后控制许多消息将如何被发送的时间。
在第四标签存在被根据当选择每个按钮在选项卡3.选择的号码的信息显示了五个按钮，每个消息的相应行被显示，根据每一行显示在选项卡3中选择的行数是一个的EditText 。
当我在标签4的EdtitText写然后换片3，后，复出标签4.文本是那里作为我写的，但是当我更改为tabr 2或标签1，则复出标签4中，文本消息2，3，4和5消失。有必要强调的是，消息1的文字仍然完好无损。
我相信，它正在发生，因为我实例化的linhas [i] [j]我oncreateview内一个新的EditText，但我不知道。当我做了尝试实例在我的OnCreate后，我改变标签4，应用程序是由异常密切。

ViewPager实例最大3次或片段。它的回收容器提出了新的看法/片段。例如，当你在你的第二页只有第一和第三的意见/片段的实例化。一个解决办法是让你的适配器上的片段的实例或使用 ViewPager.setOffscreenPageLimit(int)增加最大viewpager的意见/片段实例
