对于页面内有多个textview需要使用到该help出现的长按多个textview会出现多个helper弹框问题

[xiaoting000]

我的解决办法： 在 helper内用个static isShowing 来标记是否已经有复制弹出pop显示， 再用一个static storedHelper存放当前显示的helper, 然后再show 和 hide方法里对标记和 对storedHelper做清理操作, 具体添加代码如下:

private static boolean isShowing = false;
private static SelectableTextHelper storedHelper;

public void hideSelectView() {
        isShowing = false;
//your code
//......
}

private void showSelectView(int x, int y) {
        if(isShowing){
            storedHelper.resetStored();
        }
// your code
//.....
}

public void resetStored(){
        resetSelectionInfo();
        hideSelectView();
        mStartHandle = null;
        mEndHandle = null;
        mOperateWindow = null;
    }

showSelectView 方法最后少贴了一行：

private void showSelectView(int x, int y) {
if(isShowing){
storedHelper.resetStored();
}
// your code start
//.....
//your code end

storedHelper = this;

}

这样是可以解决的，目前这个项目处在一个探索的过程，其实实际应用到项目中还是需要很多处理的

private void showSelectView(int x, int y) {

storedHelper = this;

}

我试了好像不行啊

        mEndHandle = null;
        mOperateWindow = null;
    }

少了把isShowing设为true的步骤, 另外你这里没有判断两次长按的对象是不是同一个，如果是同一个的话，当前mOperateWindow 设为null了就会出错。

我这边是可以的，

}

private void showSelectView(int x, int y) {
        if(isShowing){
            storedHelper.resetStored();
        }
// your code
//.....
}

public void resetStored(){
        resetSelectionInfo();
        hideSelectView();
        mStartHandle = null;
        mEndHandle = null;
        mOperateWindow = null;
    }

少了把isShowing设为true的步骤, 另外你这里没有判断两次长按的对象是不是同一个，如果是同一个的话，当前mOperateWindow 设为null了就会出错。

isShowing置为true 在的if(isShowing){
storedHelper.resetStored();
}

之后有置为true， 忘了贴上来了， mOperateWindow 使用有判空的，同一个对象选择是没有问题的我这边现在也是正常使用，你那边如果有具体的问题可以贴上来看看

我的办法是去监听Activity中的dispatchTouchEvent方法。因为游标和操作弹框都是用PopupWindow，PopupWindow里的控件会消费掉触摸事件，不会传递到父控件，所以当dispatchTouchEvent被响应时，说明我点击到了外部区域，这时把游标、弹框以及背景都清空就好了

[djxf]

还行。
