我做了一个简单的fragment界面，主要是输入ID，然后向服务器查询内容后赋值回原来的界面上的textview，但是在运行的时候发生了一个奇怪的问题，一部分的textview消失了，具体很难描述，以下是整个过程的描述
这是个原始界面，在最上方输入编号，然后查询。
点击查询后，可以看见，背景内容已经加载，textview的内容已经进去了，但是加载完成后，textview
如上图，加载完成后，下面的Textview不见了，而且，连那些实现写好的静态的textview也不见了
然后，我通过弹出输入法，用输入法覆盖部分内容
像上图这样，在搜索框中点击之后，输入法会自动弹出，覆盖掉下面的内容，然后再取消
然后内容就出来了。。。
每次都是这个样子。。我觉得很奇怪，不知道什么原因导致的，谁能帮忙看看吗？谢谢
整个框架大框架是fragment+viewpage，查询用的AsyncTask查询后赋值。
上代码了，布局文件，是一个fragment_content，xml
