EditText上的数据丢失旋转设备 [英] EditText data is lost on rotating the device

问题描述

确定家伙，我用它做。我一直在使用Google的最后2天，但我无法找到确切的解决方案。每个人都在谈论configChanges以及所有那些陈词滥调事情，似乎并不在我的情况下工作。

OK guys, I am done with it. I have been googling for last 2 days but I can't find the exact solution. Everyone is talking about configChanges and all those cliche things which do not seem to work in my case .

我有一个登录界面，下设2 EditTexts。现在，这个登录界面有两个纵向和横向不同的布局。所以我不得不创建布局文件夹使用不同login.xml和布局，土地文件夹中其他login.xml。并支持方向改变我overrid在LoginActivity类onConfigurationChanged（）方法。在这种方法我称之为的setContentView（R.layout.login）方法，以便适当login.xml每天来回方向设置布局。

I have a login screen which consists of 2 EditTexts. Now this login screen has different layout for both Portrait and Landscape orientation . So I had to create one login.xml in layout folder and another login.xml in layout-land folder. And to support orientation changes I overrid onConfigurationChanged() method in LoginActivity class. In this method I call setContentView(R.layout.login) method so that appropriate login.xml is set as layout fro every orientation.

这一切后，我定义我的清单文件下面还有：

After all this I defined following in my manifest file as well:

android:configChanges="orientation|keyboardHidden"

不过还是我对着著名的老问题。如果在该EDITTEXT任何文本和装置被旋转时，该文本将丢失。我不想失去的文本。是否有可能或不？我已阅读，我们可以使用的onSaveInstanceState（捆绑savedInstanceState）方法做到这一点，我甚至已尝试过，但它din't为我工作。请帮忙。先谢谢了。

But still I am facing the famous old problem. If there is any text in the Edittext and the device is rotated, that text is lost. I don't want to lose that text. Is it possible or not? I have read that we can do it using onSaveInstanceState(Bundle savedInstanceState) method and I have even tried that too but it din't work for me. Please help. Thanks in advance.

推荐答案

使用看跌期权的方法来储存的onSaveInstanceState中值：

Use the put methods to store values in onSaveInstanceState:

protected void onSaveInstanceState(Bundle extra) {
  super.onSaveInstanceState(extra);
  extra.putString("text", "your text here");
}

和中的onCreate恢复值：

And restore the values in onCreate:

public void onCreate(Bundle extra) {
  if (extra != null) {
    String value = extra.getString("text");
  }
}

编辑（什么实际工作）：

EDIT(What actually worked):

尝试删除Android：configChanges = |从清单方向keyboardHidden

try to delete android:configChanges="orientation|keyboardHidden" from manifest.

祝你好运！
