Subitem, lists all resolution ratio of equipment support, so that user is selected.Certainly, resolution list here can also be
According to the resolution list for reading the connected actual support of display.
Method and system of the support multiresolution without Zoom display based on android system of the present invention are realized by Software for Design
What is repainted user interface according to current set resolution ratio and adjust the frame buffer (framebuffer) of Android device can
Resolution sizes are seen, to can reach point-to-point display output when resolution ratio is dynamically changed, it is ensured that whole display result is without contracting
Put operation.
Reference picture 1, the method for support multiresolution without Zoom display of the invention based on android system includes following step
Suddenly：
When step S1, Android device initialization, the video memory resolution ratio of frame buffer is set to be more than or equal to Android device
The ultimate resolution supported.
Preferably, the video memory resolution ratio of frame buffer is set to 1920*1080.Wherein, 1920 supported by Android device
Horizontal direction on video memory resolution ratio xres_virtual, the video memory point in 1080 vertical direction supported by Android device
Resolution yres_virtual.
After step S2, Android device start, the apparent resolution of frame buffer is set to the current resolution of Android device
Rate.
If for example, the current resolution of current Android device is 1440*900, by the apparent resolution of frame buffer
Xres*ysrs is set to current resolution 1440*900.
Step S3, when change Android device display resolution when, according to after renewal display resolution draw user circle
Face, while the apparent resolution of frame buffer is adjusted into the display resolution after updating.
After Android device starts, the different display of a resolution ratio is if desired changed, or need change selected
During display resolution, following operate is performed：
31) user interface (User Interface, UI) is drawn according to the display resolution (display size) after renewal.
Specifically, the WindowManagerService services and surfaceflinger services of android system ccf layer are using more
Display resolution after new, the user interface of output is drawn according to the display resolution after renewal, i.e., using WindowManager
SetForcedDisplaySize (Display.DEFAULT_DISPLAY, ssize.x, ssize.y) methods realize.Wherein,
Ssize.x*ssize.y is the display resolution after updating.For example, when the display resolution after updating is 1280*800,
Ssize.x is then set to 1280, ssize.y and is then set to 800.
32) apparent resolution of frame buffer is adjusted to the display resolution after updating.
For example, when the display resolution after renewal is 1280*800, the apparent resolution xres and yres of frame buffer are adjusted respectively
Whole is 1280 and 800.That is the frame buffer data of 1280*800 sizes is only shown.
Reference picture 2, the system of support multiresolution without Zoom display of the invention based on android system includes initialization mould
Block 1, starting module 2 and update module 3.
Initialization module 1 is used for when Android device is initialized, and sets the video memory resolution ratio of frame buffer to be more than or equal to
The ultimate resolution that Android device is supported.

Horizontal direction on video memory resolution ratio xres_virtual, the video memory point in 1080 vertical direction supported by Android device
Resolution yres_virtual.
Starting module 2 is connected with initialization module 1, for after Android device starts, by the apparent resolution of frame buffer
It is set to the current resolution of Android device.
If for example, the current resolution of current Android device is 1440*900, by the apparent resolution of frame buffer
Xres*ysrs is set to current resolution 1440*900.
Update module 3 is connected with starting module 2, for when changing the display resolution of Android device, after renewal
Display resolution draw user interface, while by the apparent resolution of frame buffer be adjusted to update after display resolution.
After Android device starts, the different display of a resolution ratio is if desired changed, or need change selected
During display resolution, following operate is performed：
31) user interface (User Interface, UI) is drawn according to the display resolution (display size) after renewal.
Specifically, the WindowManagerService services and surfaceflinger services of android system ccf layer are using more
Display resolution after new, the user interface of output is drawn according to the display resolution after renewal, i.e., using WindowManager
SetForcedDisplaySize (Display.DEFAULT_DISPLAY, ssize.x, ssize.y) methods realize.Wherein,
Ssize.x*ssize.y is the display resolution after updating.For example, when the display resolution after updating is 1280*800,
Ssize.x is then set to 1280, ssize.y and is then set to 800.
32) apparent resolution of frame buffer is adjusted to the display resolution after updating.
For example, when the display resolution after renewal is 1280*800, the apparent resolution xres and yres of frame buffer are adjusted respectively
Whole is 1280 and 800.That is the frame buffer data of 1280*800 sizes is only shown.
In summary, the method and system of support multiresolution without Zoom display of the invention based on android system are without needs
Turn back on, without changing firmware software, you can when changing the resolution ratio of the display of different resolution or more switching display,
Realize image without Zoom display；It is real suitable for there is the terminal installation of VGA or HDMI use android system
