如何从Java读取Shell命令的实时输出

这是我到目前为止的内容,但是在执行命令后打印：

try {    proc = Runtime.getRuntime().exec("du -d 1 /sdcard/");    inputStream inputStream = proc.getinputStream();    inputStreamReader inputStreamReader = new inputStreamReader(inputStream);    BufferedReader bufferedReader = new BufferedReader(inputStreamReader);    while ((line = bufferedReader.readline()) != null) {        publishProgress(i);        i++;        System.out.println(line); // it prints all at once after command has been executed.    }}catch (IOException e) {    Log.e("du","error "+e.getMessage());}

解决方法:

尝试这个：

try { proc = Runtime.getRuntime().exec("du -d 1 /sdcard/"); inputStream inputStream = proc.getinputStream(); inputStreamReader inputStreamReader = new inputStreamReader(inputStream); BufferedReader bufferedReader = new BufferedReader(inputStreamReader); while ((line = bufferedReader.readline()) != null) {    System.out.println(line); // it prints all at once after command has been executed. } proc.waitFor();}catch (IOException e) { Log.e("du","error "+e.getMessage());}
