Android open various types of file method summary

Very simply, by invoking the system's intent, we can open a variety of files, unfamiliar friends can understand the action, datatype, URI related knowledge.

The general method is as follows:

public static Intent OpenFile (String filePath) {File File = new file (FilePath), if (!file.exists ()) return null;/* get extension */st Ring End=file.getname (). substring (File.getname (). LastIndexOf (".") + 1,file.getname (). Length ()). toLowerCase (); /* depends on the type of extension mimetype */if (end.equals ("m4a") | | End.equals ("MP3") | | End.equals ("mid") | | End.equals ("XMF") | | End.equals ("ogg") | | End.equals ("wav")) {return getaudiofileintent (FilePath);} else if (end.equals ("3gp") | | End.equals ("mp4")) {return getaudiofileintent (FilePath);} else if (end.equals ("jpg") | | End.equals ("gif") | | End.equals ("png") | | End.equals ("JPEG") | | End.equals ("BMP")) {return getimagefileintent (FilePath);} else if (end.equals ("apk")) {return getapkfileintent (FilePath);} else if (end.equals ("ppt")) {return getpptfileintent (FilePath);} else if (end.equals ("xls")) {return getexcelfileintent (FilePath);} else if (End.equals ("Doc")) {return getwordfileintent (FilePath);} else if (end.equals ("PDF")) {return getpdffileintent (FilePath);} else if (end.equals ("CHM")) {return Getchmfileintent (filEpath);} else if (end.equals ("TXT")) {return gettextfileintent (filepath,false);} Else{return getallintent (FilePath);}}  Android gets a intentpublic static Intent getallintent (String param) {Intent Intent = new Intent () to open the APK file;  Intent.addflags (Intent.flag_activity_new_task);  Intent.setaction (Android.content.Intent.ACTION_VIEW); Uri uri = uri.fromfile (new File (param)); Intent.setdataandtype (URI, "*/*"); return intent;}  Android gets a intentpublic static Intent getapkfileintent (String param) {Intent Intent = new Intent () to open the APK file;  Intent.addflags (Intent.flag_activity_new_task);  Intent.setaction (Android.content.Intent.ACTION_VIEW); Uri uri = uri.fromfile (new File (param)); Intent.setdataandtype (URI, "application/vnd.android.package-archive"); return intent;} Android gets a intentpublic static Intent getvideofileintent (String param) {Intent Intent = new Intent for opening video files ("Andro Id.intent.action.VIEW "); Intent.addflags (intent.flag_activity_clear_top); Intent.putextra (" OneShot ", 0); Intent.putextRA ("Configchange", 0); Uri uri = uri.fromfile (new File (param)); Intent.setdataandtype (URI, "video/*"); return intent;} Android gets a intentpublic static Intent getaudiofileintent (String param) {Intent Intent = new Intent for opening audio files (" Android.intent.action.VIEW "); Intent.addflags (intent.flag_activity_clear_top); Intent.putextra (" OneShot ", 0); Intent.putextra ("Configchange", 0); Uri uri = uri.fromfile (new File (param)); Intent.setdataandtype (URI, "audio/*"); return intent;} Android gets a Intent public static Intent gethtmlfileintent (String param) {uri uri = uri.parse (param) used to open the HTML file.
