我正在制作一个应用程序,使用的是这个链接:

    https://github.com/harism/android_page_curl.

在那个使用位图实现页面卷曲的链接中,但是我的要求是查看卷曲,为此我转换
在位图中查看(linearlayout)并在子视图上设置onclicklistener,有关详细说明,请参见
附加图像
我的代码是:

        int width, int height, String title, String time) {


    // Upper layout of screen

        objmainlayout.setLayoutParams(new LayoutParams(
                LayoutParams.FILL_PARENT, (height -100)));
        Log.e("chectttttttttttlayout",""+(height-71));
    } else {
        objmainlayout.setLayoutParams(new LayoutParams(
                LayoutParams.FILL_PARENT, (height - 90)));
    }
    objmainlayout.setBackgroundColor(Color.WHITE);
    objmainlayout.setOrientation(LinearLayout.VERTICAL);
    objmainlayout.setPadding(10, 0, 10,0);


    for (int mindex = 0; mindex <3; mindex++)
    {
        RelativeLayout.LayoutParams objparams;
        // Layout Root View (RelativeLayout)

        RelativeLayout objrelativeinnerlayout = new RelativeLayout(context);
        if (height >= 320)
        {

在这里,我把myview的代码转换成位图,问题是如何让onclicklistener访问它?
请大家提前向我表示感谢。

最佳答案

我遇到了类似的问题。要使其工作,我有一个父布局(ContentContainer),其中包含两个子视图:
卷曲时转换为位图的内容视图
卷曲视图(OpenGL曲面)
我必须为父布局设置一个onclicklistener来捕获事件并将其发送或不发送到curlview。当事件被发送到curlview时,curlview被置于前面(使用bringtofront()方法)。否则,内容视图将显示在前面。
为了决定是否将事件发送到curlview,我使用了一个方法,如果tap在page curl区域(aprox)内,则返回true。屏幕的1/6,两侧)。此外,我有一个手势和比例检测器来检测单点和长按,这是我们需要的用户交互。当一个点击或者长按被捕捉到时,帖子(x,y)告诉我用户触摸的地方,这样我就可以启动一些活动,显示一个上下文菜单或者其他什么。
一些示例代码:

    contentContainer.setOnClickListener(null); // DO NOT REMOVE THIS, IT'S A WORKAROUND
    contentContainer.setOnTouchListener(new OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            gestureDetector.onTouchEvent(event);
            mScaleDetector.onTouchEvent(event);

            int x = (int)event.getX();
            int y = (int)event.getY();

            boolean isMoving = event.getAction() == MotionEvent.ACTION_MOVE;
            boolean isTouchDown = event.getAction() == MotionEvent.ACTION_DOWN;
            boolean isTouchUp = event.getAction() == MotionEvent.ACTION_UP || event.getAction() == MotionEvent.ACTION_CANCEL;
            boolean pageCurlArea = isPageCurlArea(x, y);

            boolean sendEventToCurlView = false;

            if (isTouchDown && pageCurlArea) {
                downInPageArea = true;
                sendEventToCurlView = true;
            } else if (downInPageArea && isMoving) {
                sendEventToCurlView = true;
            } else if (downInPageArea && isTouchUp) {
                downInPageArea = false;
                sendEventToCurlView = true;
            } else if (!downInPageArea && isMoving) {
                return false;
            }

            if (downInPageArea && isMoving && !curlViewIsOnTop) {
                bringCurlViewToFront();
            }

            if (sendEventToCurlView) {
                MotionEvent mEvent = MotionEvent.obtain(event);
                mCurlView.onTouch(v, mEvent);
            }

            return !sendEventToCurlView;
        }
    });

这是一项正在进行的工作,因为我需要修改它,使其不使用“页面卷曲区域”来区分“卷曲事件”和其他事件(单击、长按…),为此,我计划使用手势和比例检测器返回事件是否被捕获,并根据结果继续是否将事件发送到curlview。这对于在1/6页卷曲区域内执行“轻敲”和“长按”是必要的。
希望有帮助。
