Painting canvas empties, and by the path preserved, last is removed, and path is drawn in above painting canvas again；The core concept of deletion
It is the delet method that every kind of figure is added in the initialization function of painting canvas, then calls the initialization function of painting canvas again finally
Preserve bitmap.
As a preferred technical solution of the present invention, the generation data list method：For listed in data list
The multiple types of data gone out, is realized using Viewpager+Fragment and horizontally slipped page turning, including step is as follows：
Data, is changed into Byte types and realizes serializing interface by S1；
S2, inherit FragmentStatePagerAdapter and rewrite getPageTitle () therein and getItem () two
A method；
S3, take out data by getSerializableExtra () and shown in Fragment.
As a preferred technical solution of the present invention, the picture indicia module, which includes opening camera, takes pictures method of servicing
With picture approach is obtained in picture library.
As a preferred technical solution of the present invention, the unlatching camera is taken pictures method of servicing：The preservation of picture is set
Path, calling system camera are taken pictures, and receive to call the data returned after camera.
As a preferred technical solution of the present invention, picture approach is obtained in the picture library：Album picture path is obtained,
Local dimension of picture is read, preserves picture into bitmap.
The application system of a kind of drafting system based on Andriod operating systems of the present invention, using above technical side
Case compared with prior art, has following technique effect：The designed drafting system based on Andriod operating systems of the invention,
It is good with reference to Andriod platforms using the features such as smart mobile phone is small, easy to carry, cost is low, open system, complete function
