布局在屏幕旋转时会自动复制 [英] Layout duplicating itself on screen rotation

问题描述

我有一个具有EditText和Button的布局.我< include> 在我的主布局中.

I have a layout that has an EditText and a Button. I <include> it in my main layout.

我在布局和旋转方面遇到了一个怪异的问题.旋转设备(物理设备)时，它似乎在复制自身，弄乱了文本和布局.

I'm having a weird issue with the layout and rotation. It seems to duplicate itself when the device (physical) is rotated, messing up the text and layout.

在这里添加一些乱码后，它是第一次打开:

Here it is on first open, after I add some extra garble:

DSC_0013在片段启动时位于EditText中.

DSC_0013 is in the EditText on launch of the fragment.

然后，我旋转手机并添加一些不同的乱码:

Then, I rotate the phone and add some different garble:

您可以清楚地看到该问题.起初，我以为只是EditText搞砸了.但是，如果我添加了足够的文本以换行:

And you can see the issue pretty clearly. At first, I thought it was just the EditText messing up. But if I add enough text to make a new line:

我可以看到按钮也弄乱了.

I can see that the button gets messed up too.

我确实覆盖了 onSaveInstanceState ，但是其中我没有触摸EditText或它的值，它严格用于其他用途.

I do override onSaveInstanceState, but in it I don't touch the EditText or its value, it's strictly used for something else.

发生了什么以及如何解决?

What's happening and how do I fix it?

推荐答案

已修复！

事实证明不是重复的视图，EditText或Button.这是整个片段.

Turns out it wasn't the view duplicating itself, or the EditText, or the Button. It was the entire fragment.

在活动的 onCreate 中，将片段添加到xml布局中:

In my Activity's onCreate, I add the fragment to an xml layout:

private FileDetails fileDetailsFragment;

public void onCreate(Bundle savedInstanceState) {
        ...
        FragmentManager fragmentManager = getSupportFragmentManager();
        FragmentTransaction fragmentTransaction = fragmentManager
                .beginTransaction();
        fileDetailsFragment = new FileDetails(fileData);
        fragmentTransaction.add(R.id.DetailsHolder, fileDetailsFragment);
        fragmentTransaction.commit();

每次我旋转手机时，都会调用

onCreate (按原意).因此，我检查了该活动是否是第一次运行，并且效果很好.

And onCreate was being called every time I rotated the phone (as it's meant to). So I put in a check to see if the activity is being run for the first time, and it works great.

private FileDetails fileDetailsFragment;

public void onCreate(Bundle savedInstanceState) {
    ...
    if (savedInstanceState == null) {
        FragmentManager fragmentManager = getSupportFragmentManager();
        FragmentTransaction fragmentTransaction = fragmentManager
                .beginTransaction();
        fileDetailsFragment = new FileDetails(fileData);
        fragmentTransaction.add(R.id.DetailsHolder, fileDetailsFragment);
        fragmentTransaction.commit();
    } else {
        fileDetailsFragment = (FileDetails) getSupportFragmentManager().findFragmentById(R.id.DetailsHolder);
    }
