Abstract
The invention provides a zooming method and device for screen display of mobile terminals. The zooming method comprises the following steps: receiving a configuration change request of a screen density; determining a proportional relationship between a screen layout unit and a pixel unit according to the changed screen density; redrawing a system display view according to the proportional relationship. According to the zooming method and device for screen display of mobile terminals, the proportion relationship between the screen layout unit and the pixel unit is determined through changing the screen density, so that the overall zooming of the screen display of mobile terminals can be realized, and the personalized configuration demands of the users are satisfied.
Description
Technical field
The present invention relates to a kind of Zoom method and device, particularly relate to a kind of mobile terminal screen and show
Zoom method and device.
Background technology
The screen of current most of mobile terminals is shown that regulating, and is typically merely able to
Word size or part operation key icon to display are adjusted, but cannot realize entirety
Scaling, therefore, Shortcomings in terms of the whole structure display of mobile terminal, it is impossible to meet use
The individual character at family is with requiring.
Summary of the invention
It is an object of the invention to, it is provided that Zoom method that a kind of mobile terminal screen shows and device,
To realize the overall scaling that mobile terminal full screen is shown, meet users' personal allocation demand.
To achieve these goals, the invention provides the scaling side that a kind of mobile terminal screen shows
Method, including:
Receive the configuration change request of screen density；
Determine that the ratio between screen layout's unit and pixel unit is closed according to the screen density after change
System；
System display view is repainted according to described proportionate relationship.
Present invention also offers the device for zooming that a kind of mobile terminal screen shows, it is characterised in that
Including:
Request receiver module, for receiving the configuration change request of screen density；
Proportionate relationship determines module, for determining screen layout's unit according to the screen density after change
And the proportionate relationship between pixel unit；
View Drawing module, for repainting system display view according to described proportionate relationship.
Zoom method that the mobile terminal screen of the present invention shows and device, by change screen density,
And then determine the proportionate relationship between screen layout's unit and pixel unit such that it is able to realize mobile
The overall scaling change that the screen of terminal shows, meets users' personal allocation demand.

Detailed description of the invention
At Android system median surface layout unit DP i.e. DIP (device independent
Pixels, equipment independent pixel), it is a relative unit, distinct device has different display effects,
DP is relevant with device hardware, and is independent of pixel.The principle of the embodiment of the present invention is, by adjusting
The screen density that whole system shows, determines that 1 dp unit correspondence uses several pixel units to carry out
Draw, thus realize the overall scaling that screen shows.
Embodiment one
As it is shown in figure 1, the Zoom method that the mobile terminal screen that it is the embodiment of the present invention one shows
Schematic flow sheet, this Zoom method, including:
Step 101: receive the configuration change request of screen density (density)；
Step 102: determine screen layout's unit (DP) and pixel according to the screen density after change
Proportionate relationship between unit；
Step 103: repaint system display view according to described proportionate relationship.
Zoom method that the mobile terminal screen of the present embodiment shows and device, close by change screen
Degree, and then determine the proportionate relationship between screen layout's unit and pixel unit such that it is able to realize
The overall scaling change that the screen of mobile terminal shows, meets users' personal allocation demand.
Specifically, system can provide interactive interface as shown in Figures 2 to 4 to assist user to enter
Row is arranged, and Fig. 2 is the entrance arranging interface, concrete by the actual boundary shown in Fig. 3 and Fig. 4
The ratio that reduction of area is put with reference to figure to allow user carry out screen density setting.
Further, in view of the change of screen density (density) is typically in mobile terminal startup
Just can re-read and configure under state, therefore, it can during mobile terminal start next time,
Read the screen density after described change, then perform step 102 and step 103.At this moment, need
System, after the configuration change request receiving screen density, preserves the screen density after change, for
Use during start next time.
Specifically, during mobile terminal-opening, it is possible to use Android system
Surfaceflinger (interface delivery) thread is read by its read only attribute (ro.sf.lcd_density)
Take the screen density after described change, and then complete configuration.System can also be arranged to actively trigger
Restart, i.e. ask when the configuration change receiving described screen density and preserve the screen after change
After curtain density, trigger mobile terminal and restart.
If it addition, configuration change request in change after screen density illegal, then can be straight
Connect the screen density using system default.
Embodiment two
As it is shown in figure 5, it is the scaling dress shown for the mobile terminal screen of the embodiment of the present invention two
The structural representation put, this device for zooming includes:
Request receiver module 11, for receiving the configuration change request of screen density；
Proportionate relationship determines module 12, for determining that screen layout is single according to the screen density after change
Proportionate relationship between position and pixel unit；
View Drawing module 13, for repainting system display view according to described proportionate relationship.
Further, as embodiment one is introduced, in actual applications, can be when starting shooting next time
Adjusting the configuration of screen density again, therefore, this device for zooming may include that screen density preserves mould
Block, the screen density after preserving change, thus for parameter configuration during start.
In start process, mainly realize configuring by surfaceflinger thread, therefore,
Can also include: thread dispatching module, for during mobile terminal-opening, call Android
The surfaceflinger thread of system reads the screen density after described change by its read only attribute.
Additionally, in order to realize active arrangement, the device for zooming of the present embodiment, it is also possible to including:
Restart trigger module, for asking also when the configuration change receiving described screen density
After preserving the screen density after change, trigger mobile terminal and restart.
One of ordinary skill in the art will appreciate that: realize the whole of above-mentioned each method embodiment
Or part steps can be completed by the hardware that programmed instruction is relevant.Aforesaid program is permissible
It is stored in a computer read/write memory medium.This program upon execution, performs to include
