小编Nat*_*lie的帖子

我有一个非常简单的类,我写了一个非常简单的Junit测试,这是成功的.

现在我将实现Parcelable添加到我的类中.我的代码很好地编译并且应用程序运行良好,但我的Junit测试不再编译,因为NoClassDefFoundError:android/os/Parcelable

我不是要测试parcelable属性,我只需要我的测试来编译.

我想有一个配置问题,但我找不到要修改的内容来解决这个问题.

我在Android Studio 2.3上工作.我已经尝试重启android studio/rebuild/clean ...

帮助将是apreciated.

我希望在 contraintlayout 内有一个分割器，以便能够更改 2 个图像视图的相对大小。

示例：拖动下面的双箭头时，应根据箭头位置调整 image1 / image2 的大小。

为此，这是我的布局

我的分隔图像上有一个 onTouchListener ：

 View.OnTouchListener dividerTouchListener = new View.OnTouchListener() {

        private float  mInitialY;


        @Override
        public boolean onTouch(View view, MotionEvent motionEvent) {
            switch (motionEvent.getActionMasked()) {
                case MotionEvent.ACTION_DOWN:
