在本发明实施例中，可以根据需要设定节点区域的大小。
请参阅图2，在本发明实施例中，可以将最左边的节点定义为根节点，一个思维导图中有且只有一个根节点，可以从根节点中分发出的三个节点作为根节点的子节点。对于每一个子节点来说，均有一个父节点，可以见父节点设置在子节点的左边，父节点以及和该父子点分发的子节点可以成为同一级节点。若某一节点还分发有子节点，则该节点作为分发后的子节点。请继续参阅图2，在本发明实施例中，同一个父节点分发出来了三个子节点，三个字节可以互称为兄弟节点。
S2、获取用户在当前界面输入的笔迹信息，根据笔迹信息确定起始点位于节点区域内的笔迹；
在本发明实施例中，在创建了若干个节点后，用户可以将输入方式切换为手写模式，通过手写模式在当前界面输入笔迹。本发明实施例在检测到用户在操作界面输入笔迹之后，获取用户在当前界面的笔迹信息。
在本发明实施例中，可以将当前界面作为一个坐标系，以当前界面的中心点作为原点，确定用户笔迹的起始点坐标和节点区域的坐标，通过遍历所有的节点区域，可以确定起始点位于节点区域内的笔迹。
S3、将笔迹与节点区域绑定，并确定笔迹所占的笔迹区域；
在本发明实施例中，可以根据笔迹的坐标点信息，确定笔迹所占的笔迹区域。该笔迹区域可以为包含该笔迹的矩形区域。
S4、在笔迹区域不被节点区域包含时，将节点区域扩容至节点区域和笔迹区域的合集区域；
在本发明实施例中，在笔迹区域不被节点区域包含时，判断此时需要对节点区域进行扩容，以适应笔迹区域的大小。本发明实施例中节点区域和笔迹区域的合集区域可以为包含节点区域和笔迹区域的最小矩形区域。
在本发明实施例中，在笔迹区域被节点区域包含时，无需对节点区域进行扩容。
请参阅图3-4，为本发明实施例在节点区域内输入一条笔迹和两条笔迹后的节点区域扩容示意图。
S5、获取所有节点的位置，根据节点的位置将所有的节点进行连接，并根据节点区域绘制节点框。
在本发明实施例中，可以通过调用全局绘制的方式，连接同一级节点的父节点和子节点，并根据节点区域的大小绘制节点框，以生成思维导图。
本发明实施例通过获取用户在当前界面输入的笔迹信息，根据所述笔迹信息确定起始点位于节点区域内的笔迹，将所述笔迹与所述节点区域绑定，并确定所述笔迹所占的笔迹区域，在所述笔迹区域不被所述节点区域包含时，将所述节点区域扩容至所述节点区域和所述笔迹区域的合集区域，能够根据用户输入笔迹的位置以及大小，对笔迹绑定的节点区域进行动态调整，使得节点区域能够合理适应节点内容，无需人为拉拽节点区域，不仅能够提高生成思维导图的效率，且自动动态调整节点区域的大小，还能够有效提高生成思维导图的效果。
在一个实施例中，若干个节点包括一个第一级父节点和若干个第一级子节点，在当前界面创建若干个节点，还包括：
同一级子节点之间的垂直方向间隔距离保持一致且不变，同一级父节点和子节点的水平方向间隔距离保持一致。
在本发明实施例中，节点与节点之间的间隔大小保持不变，在任意操作一个节点时，例如在进行增删节点、对节点区域进行扩容、缩容等操作时，整个思维导图的位置发生适应性变化，从而可以保证思维导图的整体联动性。
在一个实施例中，在当前界面创建若干个节点之后，还包括：
响应用户输入的节点创建指令，在当前界面的预设位置创建节点；
或响应用户输入的节点删除指令，将待删除节点从当前界面中删除。
在本发明实施例中，可以根据用户输入的节点创建指令，在当前界面创建新的节点，用户可以通过当前界面切换为节点选择模式，并在当前界面上选中一个
节点，通过操作工具栏，选择具体如何创建节点。
请参阅图5，在显示思维导图的操作工具栏之后，用户可以点击左边按钮删除选中节点，可以点击上方按钮向上添加兄弟节点，可以点击右边按钮在选中节点右侧添加一个子节点，可以点击下方按钮向下添加一个兄弟节点。
当用户输入节点创建指令，若为子节点创建指令，则添加一个子节点，若为兄弟节点创建指令，则获取当前的选中节点的父节点，调用父节点的创建子节点方法，将子节点创建到指定位置。
当用户输入节点删除指令，获取选中节点在其父节点的位置，调用子节点结合的方法，从集合中删除该节点，并解绑关系。
在一个实施例中，思维导图生成方法还包括：
在删除笔迹后，当节点区域内的所有笔迹区域组成的并集区域包含在节点区域内时，将节点区域缩容至并集区域。
在本发明实施例中，用户可以将选中的笔迹进行删除，在删除笔迹之后，节点区域内的笔迹发生变化，笔迹锁组成的笔迹区域也发生变化，当节点区域内的所有笔迹区域组成的并集区域包含在节点区域内时，将节点区域缩容至并集区域的大小，以适应笔迹区域的大小。在本发明实施例中，可以设置节点区域大小的下限值和上限值，在对节点区域进行扩容或缩容时，不超过下限值和上限值。
请参阅图6，为本发明实施例提供的删除笔迹后节点区域进行缩容的示意图。
在一个实施例中，思维导图生成方法还包括在对节点区域进行缩容或扩容后，确定节点区域的最新区域，根据最新区域和缩容或扩容之前的节点区域，确定四个方向的偏移值，将偏移值赋值至根节点上，更新根节点的位置，并基于更新后的根节点位置，重新计算并确定所有子节点的位置。
请参阅图7，为本发明实施例提供的一种三级思维导图。
请参阅图8，在三级思维导图中，在其第二级节点中，添加了一条从左往上的笔迹，导致其子节点即第三级节点向右边移动，且其上方的兄弟节点向上移动。
请参阅图9，在图8的基础上，在第三级节点中从右往下画一条笔迹，导致其父节点向左移动，其父节点以及该父节点的父节点向左移动，父节点的兄弟节
点向下移动。
在本发明实施例中，步骤S2根据笔迹信息确定起始点位于节点区域内的笔迹，还可以包括以下子步骤：
S21、确定笔迹的起始点的坐标；
在本发明实施例中，可以将当前界面作为坐标系平面，以中心点作为原点，确定笔迹的起始点坐标和节点区域的坐标。
S22、遍历所有节点的节点区域，在判定到节点区域是否包含起始点的坐标时，判定笔迹位于节点区域内。
在本发明实施例中，若判断到所有的节点区域均不包含笔迹的起始点坐标，则返回空，表示该笔迹的起始点位于节点区域内，无需绑定节点。
在一个实施例中，确定笔迹所占的笔迹区域，包括：
根据笔迹的坐标点信息，确定包含笔迹的最小矩形区域，将最小矩形区域的长和宽增加预设数值，得到笔迹所占的笔迹区域。
在本发明实施例中，为了使得笔迹和节点区域的边缘保持一定的距离，本发明实施例对包含笔迹的最小矩形区域的长边和宽边增加预设数值，已得到笔迹所占的笔迹区域。例如可以在最小矩形区域的场边和宽边均增加10px、12px或14px。
在一个实施例中，根据节点的位置将所有的节点进行连接，包括：
根据节点的位置确定同一级节点中父节点与子节点的中心点，基于中心点，通过直线将父节点连接至子节点。
在本发明实施例中，在将节点连接起来之前，重新计算各个节点的位置，可以先确定根节点的位置，逐级确定其他节点的位置。具体可以为：计算子节点的宽高(onMeasure)，根据宽高调用onLayout放置子节点的位置，onMeasure里先递归其子节点，调用其子节点的onMeasure，再根据自身内部笔迹，计算得到mWidth，mHeight。onLayout内部也可以根据参数left，top，right,bottom来分配自己的的区域(cellRegion)，然后再递归调用其子节点的onLayout方法，以逐级确定所有的节点位置。
在本发明实施例中，可以先移动点到当前节点的右中位置(startX,startY)，再与父节点和子节点间隔的中心点(centerX,centerY)通过直线连接。再循环绘制连接其子节点，从中心点(centerX,centerY)出发，连接到(centerX,cornerY)，即连线的x方向不变，只在y方向变化，再连接到子节点的左中心(nodeRect.left,cornerY)。
在绘制了连接线之后，在drawFull中，通过在cellRegion的区域上绘制一个圆角矩形addRoundRect，绘制节点区域对应的节点框，再循环绘制节点中的笔迹集合cellShapeList，最后再循环调用子节点集合(childNoteList)的drawFull方法，以逐级绘制直至生成完整的思维导图。
实施本发明实施例，具有以下有益效果：
本发明实施例通过获取用户在当前界面输入的笔迹信息，根据所述笔迹信息确定起始点位于节点区域内的笔迹，将所述笔迹与所述节点区域绑定，并确定所述笔迹所占的笔迹区域，在所述笔迹区域不被所述节点区域包含时，将所述节点区域扩容至所述节点区域和所述笔迹区域的合集区域，能够根据用户输入笔迹的位置以及大小，对笔迹绑定的节点区域进行动态调整，使得节点区域能够合理适应节点内容，无需人为拉拽节点区域，不仅能够提高生成思维导图的效率，且自动动态调整节点区域的大小，还能够有效提高生成思维导图的效果。
进一步的，在本发明实施例中，节点与节点之间的间隔大小保持不变，在任意操作一个节点时，例如在进行增删节点、对节点区域进行扩容、缩容等操作时，整个思维导图的位置发生适应性变化，从而可以保证思维导图的整体联动性。
