    android intent打开各种文件的方法

     

    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 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"},

    {".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？
