X5-ActionMode

腾讯X5内核实现长按弹出自定义菜单方法 https://blog.csdn.net/TLuffy/article/details/109174837#commentBox

非常感谢博主的文章和帮助

上面的解决方案是屏蔽了X5自身的ActionMode，但是自定义的ActionMode是通过js的方式去解决的，那么原生有没有办法解决呢，答案是有的。

下面是代码

private WebView mWebView;

boolean isInActionMode = false;
ActionMode actionMode;
View actionView;

IX5WebViewExtension x5WebViewExtension = webView.getX5WebViewExtension();
if (x5WebViewExtension != null) {
    x5WebViewExtension.setWebViewClientExtension(new ProxyWebViewClientExtensionX());
    x5WebViewExtension.setSelectListener(new ISelectionInterfaceX());
}

                        }
                    }, 30);
                    return true;
                }

                @Override
                public void onDestroyActionMode(ActionMode mode) {
                    isInActionMode = false;
                }
            };

            Context context = getContext();
            if (context instanceof BaseActivity) {
                // 生成actionView，并通过它启动ActionMode，解决定位问题
                // actionView的大小和位置，大致和Selection相同，直接将其add到WebView中
                if (actionView != null) {
                    mWebView.removeViewInLayout(actionView);
                }

                actionView = new View(context);
                actionView.setBackgroundColor(0x33FF00FF);// 方便调试
                int width = rect1.right - rect.left;
                int height = rect1.bottom - rect.top;
                LayoutParams lp = new LayoutParams(width <= 0 ? 10 : width, height <= 0 ? 10 : height);
                lp.leftMargin = rect.left;
                lp.topMargin = rect.top;
                mWebView.addView(actionView, lp);

                // 需要延迟startActionMode，给布局actionView的时间
                actionView.post(() -> {
                    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                        actionMode = actionView.startActionMode(callback, ActionMode.TYPE_FLOATING);
                    } else {
                        actionMode = actionView.startActionMode(callback);
                    }
                });
            }
            isInActionMode = true;
        });
    }

    @Override
    public void setText(String s, boolean b) {
        System.out.println();
    }

    @Override
    public String getText() {
        System.out.println();
        return null;
    }

    @Override
    public void onRetrieveFingerSearchContextResponse(String s, String s1, int i) {
        System.out.println();
    }
}

这里面用了 mWebView.addView(actionView, lp)和mWebView.removeViewInLayout(actionView)去add和remove对应的View。 为什么不是addView和removeView呢，因为x5的webview重写了addView(View child)和removeView(View child)方法， 但是没重写addView(View child, LayoutParams params)，所以导致 通过addView(View child, LayoutParams params)方法加入的view无法通过removeView(View child)删除，所以改用了removeViewInLayout(View child)去删除。
