Description
Technical field
The present invention relates to music box technical field, specifically a kind of method of music box load initialization.
Background technology
Existing music box App, will present load animation upon actuation, which is presented the state in load, by multiple
The frame animation of picture and Android are realized, are counted the resource for the different colours for changing skin in, have been added up 40 plurality of pictures, ability
Construct the load animation of music box.
It is cumbersome that this causes picture resource to make, and installation kit refers to greatly, and memory and overhead are high, are unfavorable for the exploitation of App
And it safeguards.
Invention content
In view of the deficiencies in the prior art, the purpose of the present invention is to provide a kind of sides of music box load initialization
Method only needs two small pictures that load animation can be realized, reduces the picture resource of application by self-defined general charging assembly
With installation kit size, while memory is reduced, after further optimization, when in layout using load frame, when hiding,
It can be automatically stopped animation, effectively save memory and system resource, be easy to the exploitation and maintenance of APP.
To achieve the above objectives, the technical solution adopted by the present invention is that：
A kind of method of music box load initialization, which is characterized in that include the following steps：
Step 1, definition load frame class CommonLoadingView inherits the FrameLayout frame cloth that Android system provides
Office；
Step 2, picture variable is defined, including：Background picture mBackgroud, logo picture mCenter, is android systems
The Element Variable for the ImageView types provided of uniting；
Step 3, word variable mMessageTextView is defined, the TextView components that Android system provides are inherited；
Step 4, the collection object mAnimatorSet of animation is defined, the AnimatorSet types that Android system provides are inherited
Object；
The playing sequence of animation is specified in the collection object mAnimatorSet of animation：Be performed simultaneously for several objects or
Sequence executes；
Step 5, it is loaded into load initialization topology file Loading, obtains picture control and word control；
Step 6, animation is opened.
Based on the above technical solution, an external interface is provided, the word that user specifies is received, when being used for step 3
Text importing when modification load.
Based on the above technical solution, in step 5, the API of the load layout of Android system offer is called
LayoutInflater.from obtains system resource from the context context of current page,
The topology file R.layout.item_loading finished writing in advance is called, background picture, logo are set in topology file
The display of picture and word,
Resource picture is obtained using the context of Android system offer,
Using the power function setImageDrawable of ImageView controls, resource picture is loaded in topology file.
Based on the above technical solution, in step 6, the class ObjectAnimator for executing attribute animation is called, is referred to
Surely the method ofFloat for needing to execute the control of animation, and being provided using attribute animation, completes the attribute of specified animation,
The attribute of affiliated specified animation is：Rotation, scaling, translation or gradual change.
Based on the above technical solution, in step 6, default background picture mBackgroud specifies rotation rotations
Animation, from 0 ° of rotation to 360 °,
Giving tacit consent to logo pictures mCenter specifies scaleX and scaleY to scale animation, is zoomed in and out in x-axis and y-axis, pantograph ratio
Example is expanded to original size from 0.6 times of original size, zooms to 1.6 times of original size again later,
Above-mentioned rotation animation and scaling animation acquiescence is performed simultaneously.
Based on the above technical solution, in step 6, animation is set using the attribute initAnimation of animation
Execute the interpolation device and/or animation number of repetition of time and/or animation.
Based on the above technical solution, the interpolation device of default animation is linear interpolator LinearInterpolator,
Indicate that animation is linear change.
Based on the above technical solution, load frame class CommonLoadingView is added to window, opens animation
Realization starts to execute animation, is executed in load window onAttachedToWindow readjustments,
Correspondingly, executing stops animation in removing window onDetachedFromWindow readjustments.
Based on the above technical solution, the readjustment dispatchVisibilityChanged changed by visibility
In, it according to display or hides, opening and closing animation is arranged.
The method of music box load initialization of the present invention is only needed two small by self-defined general charging assembly
Load animation can be realized in picture, reduces the picture resource and installation kit size of application, while reducing memory, further excellent
After change, when in layout using load frame, when hiding, it can also be automatically stopped animation, effectively save memory and system money
Source is easy to the exploitation and maintenance of APP.
Description of the drawings
The present invention has following attached drawing：
The flow chart of Fig. 1 present invention.
Specific implementation mode
Below in conjunction with attached drawing, invention is further described in detail.
As shown in Figure 1, the method for music box load initialization of the present invention, includes the following steps：
