写一个java文件，运行后即可快速访问doc

下面开始：

#设置环境变量名称：ANDROID_SDK_HOME值：我的为-->G:\android-sdk#代码编译及运行把下面的代码保存为：AndroidDoc.java

import java.io.BufferedReader; import java.io.BufferedWriter; import java.io.File; import java.io.FileFilter; import java.io.FileNotFoundException; import java.io.FileReader; import java.io.FileWriter; import java.io.IOException; import java.util.Map; import java.util.UUID;  public class AndroidDoc {     private static final String ANDROID_SDK_HOME = "ANDROID_SDK_HOME";     private static final String TAG = "<script src=\"http://www.google.com/jsapi\" type=\"text/javascript\"></script>";     private static String androidSDKHome;      public static void main(String[] args) {         Map<String, String> map = System.getenv();         androidSDKHome = map.get(ANDROID_SDK_HOME);         if (androidSDKHome != null) {             System.out.println("Detected the Android SDK Installation path:"                    + androidSDKHome);             File docs = new File(androidSDKHome + "\\docs");             System.out.println("It will take several minutes, please wait...");             traverse(docs);             System.out                     .println("Operation Down!!! Now you can visit Android Doc without waiting...");         } else {             System.out                     .println("Please configure the Android SDK Environment variable (ANDROID_SDK_HOME)!");         }     }      /**      * 遍历Android SDK安装目录下的docs目录      *       * @param dir      */    private static void traverse(File dir) {         if (dir.isDirectory()) {             File[] files = dir.listFiles(new FileFilter() {                 @Override                public boolean accept(File file) {                     if (file.isFile() && file.getName().endsWith(".html")) {                         BufferedReader reader = null;                         try {                             reader = new BufferedReader(new FileReader(file));                             String buffer;                             while ((buffer = reader.readLine()) != null) {                                 if (buffer.trim().equalsIgnoreCase(TAG)) {                                     return true;                                 }                             }                         } catch (Exception e) {                             e.printStackTrace();                         } finally {                             try {                                 reader.close();                             } catch (IOException e) {                                 e.printStackTrace();                             }                         }                     } else if (file.isDirectory()) {                         return true;                     }                     return false;                 }             });             for (File file : files) {                 if (file.isDirectory()) {                     System.out.println("Scanning Folder:"                            + file.getAbsolutePath());                     traverse(file);                 } else {                     doChange(file);                 }             }         }     }     /**      * 注释html中的某行Javascript代码      *       * @param file      * @return      */    private static boolean doChange(File file) {         System.out.println("Extracting File:" + file.getAbsolutePath() + "...");         String desPath = file.getParent() + "\\" + UUID.randomUUID().toString() + ".html";         File des = new File(desPath);         BufferedReader reader = null;         BufferedWriter writer = null;         try {             des.createNewFile();             reader = new BufferedReader(new FileReader(file));             writer = new BufferedWriter(new FileWriter(des));             String buffer;             while ((buffer = reader.readLine()) != null) {                 if (buffer.trim().equalsIgnoreCase(TAG)) {                     buffer = "<!--" + TAG + "-->";                 }                 writer.write(buffer + "\n");                 writer.flush();             }             return true;         } catch (FileNotFoundException e) {             e.printStackTrace();         } catch (IOException e) {             e.printStackTrace();         } finally {             try {                 reader.close();                 writer.close();                 file.delete();                 des.renameTo(file);             } catch (IOException e) {                 e.printStackTrace();             }         }         return false;     }  }

编译运行后，即可
