1./** * 检测是否安装了某个软件 * * @param pkgName "com.bill99.kuaishua" * @param mContext * @return */ public static boolean isPkgInstalled(String pkgName, Activity mContext) { PackageInfo packageInfo = null; try { packageInfo = mContext.getPackageManager().getPackageInfo(pkgName, 0); } catch (NameNotFoundException e) { packageInfo = null; e.PRintStackTrace(); } if (packageInfo == null) { return false; } else { return true; } }
2.应用安装.apk
Intent intent = new Intent(Intent.ACTION_VIEW); intent.setDataAndType(Uri.fromFile(new File(filepath)), "application/vnd.Android.package-archive"); mContext.startActivity(intent);
3.参考网上的各种openfile方法
java代码 /*** 打开文件* @param file*/ private void openFile(File file){ Intent intent = new Intent(); intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); //设置intent的Action属性 intent.setAction(Intent.ACTION_VIEW); //获取文件file的MIME类型 String type = getMIMEType(file); //设置intent的data和Type属性。 intent.setDataAndType(/*uri*/Uri.fromFile(file), type); //跳转 startActivity(intent); //这里最好try一下，有可能会报错。 //比如说你的MIME类型是打开邮箱，但是你手机里面没装邮箱客户端，就会报错。} /*** 根据文件后缀名获得对应的MIME类型。* @param file*/ private String getMIMEType(File file) { String type="*/*"; String fName = file.getName(); //获取后缀名前的分隔符"."在fName中的位置。 int dotIndex = fName.lastIndexOf("."); if(dotIndex < 0){ return type; } /* 获取文件的后缀名*/ String end=fName.substring(dotIndex,fName.length()).toLowerCase(); if(end=="")return type; //在MIME和文件类型的匹配表中找到对应的MIME类型。 for(int i=0;i<MIME_MapTable.length;i++){ //MIME_MapTable??在这里你一定有疑问，这个MIME_MapTable是什么？if(end.equals(MIME_MapTable[i][0])) type = MIME_MapTable[i][1]; } return type; } MIME_MapTable是所有文件的后缀名所对应的MIME类型的一个String数组：Java代码 <span style="white-space: pre;"> </span>private final String[][] MIME_MapTable={//{后缀名，MIME类型} {".3gp", "video/3gpp"}, {".apk", "application/vnd.android.package-archive"}, {".asf", "video/x-ms-asf"}, {".avi", "video/x-msvideo"}, {".bin", "application/octet-stream"}, {".bmp", "image/bmp"}, {".c", "text/plain"}, {".class", "application/octet-stream"}, {".conf", "text/plain"}, {".cpp", "text/plain"}, {".doc", "application/msWord"}, {".docx", "application/vnd.openxmlformats-officedocument.wordprocessingml.document"},{".xls", "application/vnd.ms-Excel"}, {".xlsx", "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"}, {".exe", "application/octet-stream"}, {".gif", "image/gif"}, {".gtar", "application/x-gtar"}, {".gz", "application/x-gzip"}, {".h", "text/plain"}, {".htm", "text/html"}, {".html", "text/html"}, {".jar", "application/java-archive"}, {".java", "text/plain"}, {".jpeg", "image/jpeg"}, {".jpg", "image/jpeg"}, {".js", "application/x-Javascript"}, {".log", "text/plain"}, {".m3u", "audio/x-mpegurl"}, {".m4a", "audio/mp4a-latm"}, {".m4b", "audio/mp4a-latm"}, {".m4p", "audio/mp4a-latm"}, {".m4u", "video/vnd.mpegurl"}, {".m4v", "video/x-m4v"}, {".mov", "video/quicktime"}, {".mp2", "audio/x-mpeg"}, {".mp3", "audio/x-mpeg"}, {".mp4", "video/mp4"}, {".mpc", "application/vnd.mpohun.certificate"}, {".mpe", "video/mpeg"}, {".mpeg", "video/mpeg"}, {".mpg", "video/mpeg"}, {".mpg4", "video/mp4"}, {".mpga", "audio/mpeg"}, {".msg", "application/vnd.ms-Outlook"}, {".ogg", "audio/ogg"}, {".pdf", "application/pdf"}, {".png", "image/png"}, {".pps", "application/vnd.ms-Powerpoint"}, {".PPT", "application/vnd.ms-powerpoint"}, {".pptx", "application/vnd.openxmlformats-officedocument.presentationml.presentation"},{".prop", "text/plain"}, {".rc", "text/plain"}, {".rmvb", "audio/x-pn-realaudio"}, {".rtf", "application/rtf"}, {".sh", "text/plain"}, {".tar", "application/x-tar"}, {".tgz", "application/x-compressed"}, {".txt", "text/plain"}, {".wav", "audio/x-wav"}, {".wma", "audio/x-ms-wma"}, {".wmv", "audio/x-ms-wmv"}, {".wps", "application/vnd.ms-works"}, {".xml", "text/plain"}, {".z", "application/x-compress"}, {".zip", "application/x-zip-compressed"}, {"", "*/*"} }; 这个MIME类型可能不够完整，你有要补充的吗？
