包含动态按钮的旋转框架布局 [英] Rotate Frame layout which contains dynamic buttons

问题描述

我有一个 Framelayout，它在运行时在中心添加四个图像视图，它包含用户可以执行不同操作的主图像，但我面临旋转布局视图的问题

目前我正在触摸旋转按钮

public void setRotateListener() {mRotateImage.setOnTouchListener(new OnTouchListener() {@覆盖公共布尔 onTouch(查看 v，MotionEvent 事件){浮动 x = event.getX(0);浮动 y = event.getY(0);浮动 theta = getTheta(x, y);开关 (event.getAction() & MotionEvent.ACTION_MASK) {案例 MotionEvent.ACTION_POINTER_DOWN:theta_old = theta;休息;案例 MotionEvent.ACTION_MOVE:浮动 delta_theta = theta - theta_old;theta_old = theta;int 方向 = (delta_theta > 0) ?1:-1；角度 += 3 * 方向；Log.d("Tag", "旋转角度:" + obj.getHeight());obj.setRotation(角度)；通知监听器(方向)；休息;}返回真；}});}私人浮动getTheta(浮动x，浮动y){浮动 sx = x - (obj.getWidth()/2.0f);float sy = y - (obj.getHeight()/2.0f);浮点长度 = (浮点数) Math.sqrt(sx * sx + sy * sy);浮动 nx = sx/长度；浮动 ny = sy/长度；float theta = (float) Math.atan2(ny, nx);最终浮点 rad2deg = (float) (180.0/Math.PI);浮动 thetaDeg = theta * rad2deg;返回 (thetaDeg <0) ?thetaDeg + 360.0f : thetaDeg;}

但我无法得到预期的结果我也已经参考了这个链接

和放入 drawable 中的图像

I have a Framelayout which add four imageview at runtime as well in center it contains main image with which user can perform different action but i face the problem with rotate layout view

currently on touch of rotate button i'm doing this

public void setRotateListener() {
    mRotateImage.setOnTouchListener(new OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            float x = event.getX(0);
            float y = event.getY(0);
            float theta = getTheta(x, y);

            switch (event.getAction() & MotionEvent.ACTION_MASK) {
            case MotionEvent.ACTION_POINTER_DOWN:
                theta_old = theta;
                break;
            case MotionEvent.ACTION_MOVE:
                float delta_theta = theta - theta_old;
                theta_old = theta;
                int direction = (delta_theta > 0) ? 1 : -1;
                angle += 3 * direction;

                Log.d("Tag", "rotate angle : " + obj.getHeight());
                obj.setRotation(angle);
                notifyListener(direction);
                break;
            }
            return true;
        }
    });
}

private float getTheta(float x, float y) {
    float sx = x - (obj.getWidth() / 2.0f);
    float sy = y - (obj.getHeight() / 2.0f);

    float length = (float) Math.sqrt(sx * sx + sy * sy);
    float nx = sx / length;
    float ny = sy / length;
    float theta = (float) Math.atan2(ny, nx);

    final float rad2deg = (float) (180.0 / Math.PI);
    float thetaDeg = theta * rad2deg;

    return (thetaDeg < 0) ? thetaDeg + 360.0f : thetaDeg;
}

but i can't get the expected result i already refer this link as well https://github.com/rprouse/XkcdClock as well as try to rotate with gesture and animation too but it seems not working as per my move on the screen
