sendUserActionEvent()返回

Question

使用Android Studio时，当弹出窗口关闭时，我收到了以下错误。 代码可以正常工作，但是Logcat中会出现以下错误：

E/ViewRootImpl: sendUserActionEvent() returned.

Java 代码：

LayoutInflater layoutInflater = getLayoutInflater();
View popupView = layoutInflater.from(getActivity()).inflate(R.layout.dayview_popup,null);
popupWindow = new PopupWindow(popupView, Toolbar.LayoutParams.MATCH_PARENT, Toolbar.LayoutParams.WRAP_CONTENT,true);
popupWindow.setOutsideTouchable(true);

....

int[] loc_int = new int[2];
try {
    view.getLocationOnScreen(loc_int);
} catch (NullPointerException npe) {}

Rect location = new Rect();
location.left = loc_int[0];
location.top = loc_int[1];
location.right = location.left + view.getWidth();
location.bottom = location.top + view.getHeight();

popupWindow.setAnimationStyle(R.style.Animation);
popupWindow.showAtLocation(view, Gravity.TOP|Gravity.RIGHT, location.right, location.bottom);

View container = (View) popupWindow.getContentView().getParent();
WindowManager wm = (WindowManager) cntx.getSystemService(Context.WINDOW_SERVICE);
WindowManager.LayoutParams p = (WindowManager.LayoutParams) container.getLayoutParams();
p.flags |= WindowManager.LayoutParams.FLAG_DIM_BEHIND;
p.dimAmount = 0.7f;
wm.updateViewLayout(container, p);

Answer 1

你可以尝试删除代码并重新编写。也许是剪切、关闭项目，打开项目，然后将该部分粘贴回去。

这更可能是设备的问题，而不是应用程序的问题。您的应用程序没问题。以前也提出过类似的问题: sendUserActionEvent()为空

谢谢。
