Question

在我的一个应用程序中，我实现了WebView来从url加载一些数据。一切都很完美。

但是每当我试图长按并选择WebView的文本时，应用程序就会崩溃并抛出错误，如下所示：每当我尝试从EditText onLongPress事件中选择文本时，它甚至会抛出错误。

我只是无法理解为什么会抛出这种错误。

我已经尝试过以下网站的建议：

Illegal State exception on double clicking a edittext

How to avoid a IllegalStateException: ActionBarContextView in older app

任何人都可以为我提供此错误的解决方案。

谢谢。

最后我找到了一个解决方案，我限制了正在复制的文本，使用setCustomSelectionActionModeCallback()方法粘贴如下：

edittext.setCustomSelectionActionModeCallback(new Callback() {

        public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
            return false;
        }

        public void onDestroyActionMode(ActionMode mode) {                  
        }

        public boolean onCreateActionMode(ActionMode mode, Menu menu) {
            return false;
        }

        public boolean onActionItemClicked(ActionMode mode, MenuItem item) {
            return false;
        }
    });

从onCreateActionMode(ActionMode, Menu)返回false将阻止启动操作模式（选择全部，剪切，复制和粘贴操作）。

剪贴板管理器无法打开EditText，WebView的长按事件
