The context in the code is both the active object that invokes the function, and the first class that encapsulates the music information

 Public classMusic {PrivateString filename; PrivateString title; Private intduring; PrivateString singer; PrivateString type; PrivateString size; PrivateString FileUrl;  PublicMusic (String filename,string title,intduring,string singer,string type,string size,string fileUrl) {         This. FileName =filename;  This. title =title;  This. during =during;  This. Singer =singer;  This. Type =type;  This. Size =size;  This. FILEURL =FileUrl; }     PublicString toString () {return "song[filename="+filename+", title="+title+", during="+during+", singer="+singer+", type="+type+", size="+size+", Fileurl="+fileurl+"]"; }     PublicString GetFileName () {returnfilename; }     Public voidsetfilename (String filename) { This. FileName =filename; }     PublicString GetTitle () {returntitle; }     Public voidSettitle (String title) { This. title =title; }     Public intgetduring () {returnduring; }     Public voidSetduring (intduring) {         This. during =during; }     PublicString Getsinger () {returnsinger; }     Public voidSetsinger (String singer) { This. Singer =singer; }     PublicString GetType () {returntype; }     Public voidsetType (String type) { This. Type =type; }     PublicString GetSize () {returnsize; }     Public voidsetSize (String size) { This. Size =size; }     PublicString Getfileurl () {returnFileUrl; }     Public voidSetfileurl (String fileUrl) { This. FILEURL =FileUrl; }    }

Here is the help class for manipulating the database with the cursor.

 Public classmusichelper{ Public Staticlist<music> songs =NewArraylist<music>();  Public StaticList<music>getallsongs (Context context) {Cursor Cursor1= Context.getcontentresolver (). Query (MediaStore.Audio.Media.EXTERNAL_CONTENT_URI,NULL,NULL,NULL,NULL);            Getcorrsongs (Cursor1); Cursor Cursor2= Context.getcontentresolver (). Query (MediaStore.Audio.Media.INTERNAL_CONTENT_URI,NULL,NULL,NULL,NULL);        Getcorrsongs (CURSOR2); returnsongs; }     Public Static voidgetcorrsongs (cursor cursor) {Music song=NULL; if(Cursor! =NULL){             while(Cursor.movetonext ()) {String filename=cursor.getstring (Cursor.getcolumnindexorthrow (MediaStore.Audio.Media.DISPLAY_NAME)); String title=cursor.getstring (Cursor.getcolumnindexorthrow (MediaStore.Audio.Media.TITLE)); intDuring =Cursor.getint (Cursor.getcolumnindexorthrow (MediaStore.Audio.Media.DURATION)); String singer=cursor.getstring (Cursor.getcolumnindexorthrow (MediaStore.Audio.Media.ARTIST)); String type=cursor.getstring (Cursor.getcolumnindexorthrow (MediaStore.Audio.Media.MIME_TYPE)); String size=cursor.getstring (Cursor.getcolumnindexorthrow (MediaStore.Audio.Media.SIZE)); String Date=cursor.getstring (Cursor.getcolumnindexorthrow (MediaStore.Audio.Media.DATA)); Song=NewMusic (filename,title,during,singer,type,size,date);            Songs.add (song);        } cursor.close (); }    }}

The content of the parameter is passed in with the activity's this reference.

Allsongs = musichelper.getallsongs (this);
