Abstract
The invention belongs to the field of touch screen equipment of an Android system and provides the Android system based writing superposition method. The method includes: setting an interface background of a writing program to be fully transparent; adding a canvas of the writing program to a first floating window; setting the first floating window to enable the same to cover interfaces of all application programs. With the method, the canvas of the writing program is always located above the interfaces of other application software, normal display of the other application software are unaffected, the function of writing superposition in the interfaces of the other application software is realized, and consumer use is facilitated.
Description
Technical field
The present invention relates to the touch panel device field based on Android system, particularly relate to and superpose Writing method in based on the touch panel device of Android system.
Background technology
Along with the development of intelligent Android system and touch screen technology, the various Android application software applied on touch-screen are arisen at the historic moment, and the software write by touch-screen such as notepad is exactly one wherein.
But, existing writing software is single realize writing function, cannot use alternately, open other application software with other application software such as e-book, video player etc., writing software will fall back on backstage, can not realize in other software interfaces, superpose the function of writing.
Summary of the invention
The technical problem to be solved in the present invention is, for the deficiencies in the prior art, and provides a kind of and can superpose the method for writing in other application software of Android system.
The technical solution adopted for the present invention to solve the technical problems is: provide a kind of superposition Writing method based on Android system, it is characterized in that, comprising:
Writing program interface background all-transparent is set;
The painting canvas of writing program is added into the first suspended window;
Arranging the first suspended window makes it can cover the interface of all application programs.
Further, the method also comprises:
Create quick botton;
This quick botton is added into the second suspended window;
Arranging the second suspended window makes it cover all interfaces.
Further, described first suspended window that arranges makes its step that can cover all Application Program Interfaces comprise: the type property value arranging described first suspended window is 2002; Described second suspended window that arranges makes its step covering all interfaces comprise: the type property value arranging described second suspended window is 2003.
Further, the method also comprises:
AddView and removeView function is write in the click event of quick botton;
Press quick botton, judge currently whether be in superposition and write state;
If so, then by calling removeView function, painting canvas is removed;
If not, then by calling addView function, add painting canvas.
Further, the described step arranging writing program interface background all-transparent specifically comprises:
Creating xml file, is #0000 by definition transparency, setting program interface background all-transparent;
In AndroidManifest.xml, the activity of this xml file of application is registered.
Implement technical scheme of the present invention, there is following beneficial effect: by the interface background of Transparence Display writing program, and by the painting canvas top set of writing program, the normal display of other application software is not affected on the interface making painting canvas always can be in other application software, realize in other software interfaces, superpose the function of writing, be user-friendly to.
Accompanying drawing explanation
Fig. 1 is that the present invention realizes superposing the method flow diagram write.
Embodiment
Below in conjunction with specification drawings and specific embodiments, the invention will be further described.
The painting canvas of writing program by writing program is set to transparent effect, and is added into window in the mode of suspended window by the present invention, thus reaches the effect superposing and write.As shown in Figure 1, the method comprises the following steps:
S101, arranges writing program interface background all-transparent, specifically comprises:
An xml file is created under res/values/, in this document by definition transparency be #0000, setting program interface background all-transparent, can directly carry out in this document the definition of transparency, also can alternative document defines by reference variable realize, #0000 represents that transparency is all-transparent;
Above-mentioned xml file is applied to activity, registers in AndroidManifest.xml to activity, the method for the setting program interface background all-transparent that xml file is defined can be applicable to program.
S102, in activity file, creates the first suspended window, by calling addView function, the painting canvas of writing program is added into the first suspended window;
S103, is set to 2002 by the type property value of the first suspended window, and the first suspended window can be covered on the interface of all application programs.
So far, can realize in the interface of other application programs, superpose the effect of writing.
The method is further comprising the steps of:
S104, creates a quick botton;
S105, in activity file, creates the second suspended window, by calling addView function, quick botton is added into the second suspended window;
S106, is set to 2003 by the type property value of the second suspended window, by the second suspended window top set, makes quick botton can cover on all interfaces;
S107, writes addView and removeView function in the click event of quick botton;
S108, presses quick botton, judges currently whether to be in superposition and to write state;
S109, if so, then by calling removeView function, removes painting canvas, reaches and closes the writing function effect of superposition;
S110, if not, then by calling addView function, adds painting canvas, reaches and opens the writing function effect of superposition.
By above operation, when running any application, arbitrarily can open or closing superposition writing function.
Realize superposing the specific works flow process of writing as follows:
After Android device start, automatically can generate a desktop suspension quick botton, this button is present among any interface;
Open any file, as video file or text etc., click suspension quick botton, the painting canvas of writing program can be opened, carry out remarks and write;
Again click suspension quick botton, pack up the painting canvas of writing program, cannot superpose again and write.
