方法一：

这是方法，添加到你的应用程序中即可，比较简陋，呵呵！public void execShell(String cmd){        try{              //权限设置            Process p = Runtime.getRuntime().exec("su");              //获取输出流            OutputStream outputStream = p.getOutputStream();            DataOutputStream dataOutputStream=new DataOutputStream(outputStream);            //将命令写入            dataOutputStream.writeBytes(cmd);            //提交命令            dataOutputStream.flush();            //关闭流操作            dataOutputStream.close();            outputStream.close();       }         catch(Throwable t)          {               t.printStackTrace();              }     }

方法二：

public void execCommand(String command) throws IOException {    Runtime runtime = Runtime.getRuntime();    Process proc = runtime.exec(command);    try {        if (proc.waitFor() != 0) {            System.err.println("exit value = " + proc.exitValue());        }        BufferedReader in = new BufferedReader(new InputStreamReader(                proc.getInputStream()));        StringBuffer stringBuffer = new StringBuffer();        String line = null;        while ((line = in.readLine()) != null) {            stringBuffer.append(line+" ");        }        System.out.println(stringBuffer.toString());     } catch (InterruptedException e) {        System.err.println(e);    }finally{        try {            proc.destroy();        } catch (Exception e2) {        }    }}
