In lrc files, per one lyrics of behavior, it is the corresponding time interval of the lyrics in ［ ］ bracket, during display, is generally parsed
It is separated into time parameter array and lyrics content array.
When realizing rolling lyrics effect, before using timer, the side of whole painting canvas is redrawn at interval of how many millisecond
Formula realizes the highlighted word for word lyrics.Have a disadvantage in that：Take resource many, overhead is big, and animation efficiency is not ideal enough.
The content of the invention
, can be word for word it is an object of the invention to provide a kind of lyric display method for defect present in prior art
The display lyrics simultaneously form animation effect, control the display time by keyFrameAnimation, animation effect is smooth, attractive in appearance, accounts for
Few with resource, overhead is small, improves operational efficiency.
To achieve the above objectives, the present invention is adopted the technical scheme that：
A kind of lyric display method, it is characterised in that comprise the following steps：
Step 1, when needing the display lyrics, lyrics original text to be shown and display relevant information are obtained；
The display relevant information, at least including following information：
The display time accounting of the lyrics, is specifically included：In the display time accounting of preposition blank, the lyrics during display of each word
Between accounting；
Step 2, by the lyrics to be shown of bottom, shown using direct drafting mode；
Step 3, for the lyrics to be shown on upper strata, the display speed of each word is calculated：Accounted for according to the display time of each word
Than, and the word word length, converse show the word needed for display speed；
Step 4, for the lyrics to be shown on upper strata, mode is rendered using part, by the word of each in the lyrics, from left to right successively
Display；
And：When part is rendered, time control is carried out according to the display speed of each word with keyFrameAnimation.
On the basis of above-mentioned technical proposal, time accounting is expressed as a percentage,
If certain row lyrics has n word, then：Word 1 arrives word n display time accounting, add the row lyrics preposition blank it is aobvious
Show time accounting, equal to 100%.
On the basis of above-mentioned technical proposal, the calculation of time accounting is：（The word end time-word time started）/
Row total time, the row total time is total display time of n word.
On the basis of above-mentioned technical proposal, when running into non-Chinese character or non-Chinese character string, in the non-Chinese character
Or increase space after non-Chinese character string.
On the basis of above-mentioned technical proposal, when running into non-Chinese character or non-Chinese character string, in the non-Chinese character
Or increasing space after non-Chinese character string, the space sets holding time to be 0.01 second.
On the basis of above-mentioned technical proposal, when running into non-Chinese character or non-Chinese character string, attempt to carry out mess code inspection
Survey, determine whether non-Chinese character or non-Chinese character string need to be converted to Chinese.
On the basis of above-mentioned technical proposal, if the two neighboring word time started is identical, latter word is delayed 0.1
Second display.
Lyric display method of the present invention, can word for word show the lyrics and form animation effect, pass through
KeyFrameAnimation controls the display time, and animation effect is smooth, attractive in appearance, and occupancy resource is few, and overhead is small, improves
Operational efficiency.
Brief description of the drawings
The present invention has drawings described below：
The effect diagram of Fig. 1 music App lyrics dynamic rolling.
The display time accounting example of Fig. 2 lyrics.
The flow chart of Fig. 3 present invention.
Embodiment
The present invention is described in further detail below in conjunction with accompanying drawing.
As shown in figure 3, lyric display method of the present invention, comprises the following steps：
Step 1, when needing the display lyrics, lyrics original text to be shown and display relevant information are obtained；
The display relevant information, at least including following information：
The display time accounting of the lyrics, is specifically included：In the display time accounting of preposition blank, the lyrics during display of each word
Between accounting, it is shown in Figure 2,
Time accounting is expressed as a percentage,
If certain row lyrics has n word, then：Word 1 arrives word n display time accounting, add the row lyrics preposition blank it is aobvious
Show time accounting, equal to 100%；
The calculation of time accounting is：（The word end time-word time started）/ row total time, the row total time is n word
Total display time；
In following step, the lyrics to be shown are at least divided into two layers（For example：It can be described as top layer and bottom）It has been shown that, two layers
Lyrics content is identical；
Step 2, by the lyrics to be shown of bottom, shown using direct drafting mode；
Step 3, for the lyrics to be shown on upper strata, the display speed of each word is calculated：Accounted for according to the display time of each word
Than, and the word word length, converse show the word needed for display speed；
Step 4, for the lyrics to be shown on upper strata, mode is rendered using part, by the word of each in the lyrics, from left to right successively
Display；
And：When part is rendered, time control is carried out according to the display speed of each word with keyFrameAnimation；
For example：Part is carried out using layer mask attributes to render；
Although mask is a layer, but it can't show that it is that former layer contents are controlled with the alpha value of oneself
The layer whether rendered：If mask alpha value is 1, that former layer, which will be rendered, to be come, conversely, would not wash with watercolours
Dye and, would not also show, but it is transparent；
And because mask is layer, mask addition CAAnimation can be given, so just can with mask animation come
Former layer is allowed from left to right gradually to show；
KeyFrame is a time/value pair, and a particular state in special time can be defined by it, i.e., crucial
Frame, and different Interpolator can be defined between two keyFrame, just look like the splicing of multiple animations, first
The end point of individual animation is the starting point of second animation.
On the basis of above-mentioned technical proposal, when running into non-Chinese character or non-Chinese character string, in the non-Chinese character
Or increase space after non-Chinese character string.
On the basis of above-mentioned technical proposal, when running into non-Chinese character or non-Chinese character string, in the non-Chinese character
Or increasing space after non-Chinese character string, the space sets holding time to be 0.01 second.
On the basis of above-mentioned technical proposal, when running into non-Chinese character or non-Chinese character string, attempt to carry out mess code inspection
Survey, determine whether non-Chinese character or non-Chinese character string need to be converted to Chinese.
On the basis of above-mentioned technical proposal, if the two neighboring word time started is identical, latter word is delayed 0.1
Second display.
The content not being described in detail in this specification belongs to prior art known to professional and technical personnel in the field.
