本文介绍了旋转框架布局，其中包含动态按钮的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 29岁程序员，3月因学历无情被辞！ 我有一个Framelayout，它在运行时添加了四个imageview，在中心它包含主图像，用户可以使用该图像执行不同的操作但我面临旋转布局视图的问题 目前正在触摸旋转按钮我正在这样做 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; 角度+ = 3 *方向; Log.d（Tag，rotate angle：+ obj.getHeight（））; obj.setRotation（angle）; notifyListener（direction）; 休息; } 返回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; 返回（thetaDeg< 0）？ thetaDeg + 360.0f：thetaDeg; } 但是我无法得到预期的结果我已经引用此链接了 Java文件 import android.annotation.SuppressLint; import android.content.Context; import android.graphics.Bitmap;
