App Equations Of Some Geometry Figures
App is intended to to construct Certain Geometric Figures on the base points that Determine Shape. App defines the equation of the following Shapes : line, Circle ellipse, plane, sphere and ellipsoid. The line is determined by the 2 points, the circle – from 3, the plane – from 3, the sphere – from 4, the ellipse – from 5 and ellipsoid is set up from 9 points.
From Startup Activity is chooses a figure, with which to works through Press The corresponding button, for example: „A CIRCLE THROUGH TREE POINTS” - when choosing for working with circles. Appears activity with title – in this case „Avtivity circle”. On each of these activity has three buttons: „New”, "Edit", "Delete" and List of already entered corresponding to the shape type.

In the "Edit" and "Delete" buttons in advance you have to hell Choose an item from the list of already introduced corresponding to the shape type.
Button "New" serves when entering new's data figure. Sed click on the "New" button appears introduction dialogue The data of the figure: name of the figure and points, from which will be calculate equation of the figure. The points are being introduced in Table with 2(X, Y) or 3(X,Y,Z) columns .
The points at storage control each other and he can't there are recurring themselves. With a press button "Save" the calculated equation and the data of the figure are stored in SQLite databases, with the name "equationCurvsAndSurfacs.db" and a list of the already introduced corresponding to the shape type is being renewed.
With the "Edit" button is displayed dialogue with same data for the figure plus the calculated Equation. And if it changes the name of the figure and points for her onstruction and presses button "Save", then the new Figure is stored like new simple together with a calculation and the equation, The data of the the old figure remain.
In the dialogue after the the "Edit" button has a button "Print". It allows data to be used to formatted in a file with a name "AppEquationsOfSomeCurvsAndSurfases.txt" and enroll to the directory of the device. After pressing of the button "Print" is shows activity with a list of Directories of the device, with item selection of it, the content of the directory is displayed in List of species wood, if chosen per directory from him is green butt with name "Save", by pressing appears to him dialogue with Button „Local saving”, which allows File "AppEquationsOfSome CurvsAndSurfases.txt"to be stored in the selected Directory.
