Embodiment Construction

[0042] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0043] Such as figure 1 , 2 , 3, the implementation method of the moving picture display progress bar control of the audio frequency spectrum described in the present invention, first based on the View custom control, by custom processing spectrum drawing and progress bar drawing, custom processing touch and button events, realize the spectrum The display and interaction of the animation display and the progress bar, and the audio spectrum and the progress bar are superimposed in the same area, see figure 1 , 2 as shown,

[0044] in:

[0045] Overload the onDraw method to realize the dynamic display of spectrum data, and draw the playback progress and buffer progress at the same time.

[0046] Overload the onTouchEvent method to realize the progress bar drag operation,

[0047] This implements a control that can drag the progress and display the audio s...

Abstract

The invention relates to a motion graph display progress bar control achievement method of an audio frequency spectrum. The method is characterized in that firstly custom processing is conducted on a touch and button event based on a View custom control by conducting custom processing on frequency spectrum drawing and progress bar drawing, presenting and interacting of frequency spectrum dynamic displaying and a progress bar are achieved, and the audio frequency spectrum and the progress bar are laminated and displayed in the same area, wherein an onDraw method is reloaded, frequency spectrum data dynamic display is achieved, progress playing and cache progress drawing are conducted simultaneously, an onTouchEvent method is reloaded, the progress bar dragging operation is achieved, and therefore the control of which the progress can be dragged and which can display an audio frequency spectrum is achieved. According to the motion graph display progress bar control achievement method of the audio frequency spectrum, the audio frequency spectrum data is subjected to motion graph display, drawing is conducted and presenting and interacting of the progress bar are conducted on the audio frequency spectrum data at the same time, and a richer frequency spectrum motion graph display effect is provided.

Description

technical field [0001] The invention relates to the technical field of self-defined controls (self-drawing controls) in Android (Android system), in particular to a method for realizing a progress bar control of an audio spectrum moving picture display. Namely: the implementation method of superimposing and displaying the progress bar control in the moving picture of the audio frequency spectrum. Background technique [0002] In Android, custom controls mainly include two categories: [0003] The first category, combined custom controls, refers to the use of various interface controls provided by the system, which are packaged into custom controls including multiple system controls through customization, and the code handles the interaction of each sub-control internally to simplify the use. [0004] The second category, self-drawing controls, refers to custom controls that inherit various interface controls provided by the system and use codes to measure, draw, and process...
