Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

In the embodiment of the present invention, after receiving the slide show instruction input by the user, the Android device sequentially loads and plays all the pictures stored in the media library according to the preset playback order, realizing that only one operation can be completed in the Android device. Autoplay of pictures in all folders.

The realization of the present invention is described in detail below in conjunction with specific embodiment:

Embodiment one

Fig. 1 shows the implementation process of the method for playing pictures provided by Embodiment 1 of the present invention, which is described in detail as follows:

In step S101, an input slide show instruction is received.

In this embodiment, the user first clicks the photo album button to enter the photo album of the Android device, and then selects a slide show, and the Android device can sequentially load and play all the pictures stored in the Android device according to the preset playback order. These pictures are stored in at least in two different folders.

In addition, before performing this step, it may also include: saving the information of all pictures stored in the Android device to the media library; and, under preset conditions, the Android device triggers the media library to scan the pictures, and simultaneously As a result the media library is updated.

Wherein, the preset condition of this embodiment is: the Android device is turned on or the picture is increased or the picture is reduced, as long as one of them is satisfied, the media library can be triggered to scan the picture, and the information of the newly added picture in the Android device will be added to the media library Delete or delete the information of the deleted pictures.

Wherein, the information of each picture in all folders in the Android device is stored in the form of a data table in the media library, and the information includes the ID of the picture, the index of the folder where the picture is located, the creation time of the picture, the picture, and can also include The storage path of the picture, the width of the picture, the height of the picture, the encoding format of the picture, etc.

In step S102, all pictures stored in the Android device are sequentially loaded and played according to a preset playing sequence, and these pictures are stored in at least two different folders.

In this embodiment, a playback data source is created first, and the information of all pictures in the media library is loaded into the internal memory through the playback data source. Among them, the playback data source is an object. The main function of this object is to realize the query of each folder in the media library, and any picture in the media library can be loaded to the memory at will. The playback data source is actually the management of the media library. An object or tool for the information of each picture in each folder.

In actual application, you can set the query condition of the playback data source to be the index BUCKET_ID of the folder, so that the information of all the pictures under all the folders stored in the media library will be queried by the index of the folder. Specifically The execution statement is as follows: mWhereClause=ImageColumns.BUCKET_ID.

Secondly, sort the information of all pictures loaded into the internal memory according to the predetermined playback order. Among them, in actual application, you can set to sort in ascending or descending order according to the creation time of the pictures, or you can sort in other ways. For example, the following sorts the pictures in descending order based on the creation time of the pictures and the index of the pictures , the specific execution statement is as follows: mOrderClause=ImageColumns.DATE_TAKEN+"DESC,"+BaseColumns._ID+"DESC", where DATE_TAKEN represents the creation time of the image, and BaseColumns._ID represents the index of the image.

Finally, all pictures are played sequentially according to the sorted picture information. Wherein, after arranging the information of all the pictures in order, the Android device can play all the pictures in the internal memory in the form of a slide show from the first picture to the end. When playing a picture specifically, it is first necessary to decode the picture to obtain a thumbnail of the picture, and then play the picture according to the thumbnail. As for how to realize the slide show of the picture in detail, it is the same as the prior art, and will not be repeated here.

In this embodiment, after receiving the slide show instruction input by the user, the Android device sequentially loads and plays all the pictures stored in the media library according to the preset playback order, realizing that all pictures in the Android device can be played automatically with only one operation. The pictures in the folder, instead of having the user enter each folder, select the picture for slide show, and the user operation is simple.

Those of ordinary skill in the art can understand that all or part of the steps in the methods of the above-mentioned embodiments can be completed by instructing related hardware through a program, and the corresponding program can be stored in a computer-readable storage medium. Media, such as ROM/RAM, magnetic disk or optical disk, etc.
