[Bug]: Window position jumps when window content size changes on Android 13-14

[ElliotAl86]

Framework Version [Required]

Source code of v12.0

Issue Description [Required]

Hello!
I encountered window position jumps when changing the content size.
This only applies to the global floating window.
I can reproduce this bug on my physical device with API level 33 and in the Android Studio emulator with API 33 and 34. It’s not reproducible on API levels 32 or 35-36 in the emulator.

Steps to Reproduce [Required]

For tests I used sources of v12.0 and changed EasyWindow initialization in method showGlobalWindow() like this:

EasyWindow.with(application)
        .setContentView(R.layout.expanding_layout)
        .setGravity(Gravity.END | Gravity.BOTTOM)
        .setYOffset(200)
        // 设置指定的拖拽规则
        .setWindowDraggableRule(springBackWindowDraggableRule)
        .setOnClickListenerByView(R.id.root_container, new OnWindowViewClickListener<LinearLayout>() {

            @Override
            public void onClick(@NonNull EasyWindow<?> easyWindow, @NonNull LinearLayout view) {
                ImageView firstView = view.findViewById(R.id.first_part);
                if (firstView.getVisibility() == View.VISIBLE) {
                    firstView.setVisibility(View.GONE);
                } else {
                    firstView.setVisibility(View.VISIBLE);
                }
            }
        })
        .setOnWindowLifecycleCallback(new OnWindowLifecycleCallback() {

            @Override
            public void onWindowCancel(@NonNull EasyWindow<?> easyWindow) {
                // 在窗口消失的时候回收资源，避免 LeakCanary 一直报内存泄漏，关于这点框架文档有介绍，详情请看文档
                easyWindow.recycle();
            }
        })
        .show();

Also added 1 layout file (expanding_layout.xml):

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/root_container"
    android:orientation="horizontal"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content">

    <ImageView
        android:id="@+id/first_part"
        android:layout_width="100dp"
        android:layout_height="100dp"
        android:visibility="gone"
        android:src="#FFAA00" />

    <ImageView
        android:id="@+id/second_part"
        android:layout_width="100dp"
        android:layout_height="100dp"
        android:src="#FFAA00AA" />

</LinearLayout>

Steps to reproduce:

1. Modify sources as above
2. Show global floating window
3. Move window to new position and click to change window size (repeat if needed)

Hello, I have investigated the problem. It's a system issue and there is no good solution for it at present.

[ElliotAl86]

Did you find any confirmation or relation indicating that it is a system bug itself?
Unfortunately, I haven’t found any issues related to this on issuetracker.google.com. And I don’t fully understand the implementation to pinpoint where the error occurs, which makes it difficult for me to create a minimal reproducible sample to file an issue report.
There are apps (e.g., Shazam) that don’t have this issue with floating windows. This suggests that the problem may depend on the implementation or at least has a possible workaround.

[getActivity]

You can try using WindowManager to see if there is the same problem?

[getActivity]

If you find that there is no problem using WindowManager but the framework has issues, it proves that my conclusion is wrong. Please let me know and I will handle the problem properly.

[ElliotAl86]

Unfortunately, I’m not very experienced with Android, and I don’t know how to properly use system APIs. I can certainly try, but I’ll likely achieve worse results than you, since you’ve been doing this library for years. If your expertise suggests there’s no good solution, then that’s fine. Nevertheless, thank you for your hard work.

@getActivity Hey again, could this issue be reopened? This issue was solved by the author of this library, I tested its latest commit and it really works in practice.

[getActivity]

@ElliotAl86 How did he solve this problem?

[ElliotAl86]

@getActivity The issue was resolved in this PR. I'm not the author of these changes, and I'm not competent enough to adapt them to this project. I only tested the library, and I no longer experience this problem on my Android 13.

@ElliotAl86 Hello, the issue has been fixed. Please use the aar package above to help test if there are still any problems. If there are no issues, I will post it to Jitpack

[ElliotAl86]

@getActivity It works well on my physical device with Android 13, this problem is gone!

• English：Hello, the latest version has been published, it's important to note that I made some code changes, you need to manually call easyWindow. SetCanPlayMoveAnimation(false) to solve this problem, if the default forced changes, leads to soft keyboard pop-up without animation, So this option needs to be manually called by you to take effect, because the scenario of modifying the window size after moving the window is relatively rare. The Bug that causes the window to jump can only be solved by manually calling the API.

• Chinese：你好，最新版本已发布，需要注意的是我做了一些代码改动，你需要手动调用 easyWindow.setCanPlayMoveAnimation(false) 才能解决这一问题，如果默认强制修改，则会导致软键盘弹出时没有动画，所以这个选项需要你手动调用才能生效，因为移动窗口后再修改窗口大小的场景比较少见，导致窗口跳动的 Bug 只能通过手动调用 API 解决。
