java - 使用 onClick 执行多个 shell 命令

Question

这是我正在尝试制作的示例:

final String[] hwdebug1 = {"su","-c","echo hello > /system/hello1.txt"};

                 try {
                     Runtime.getRuntime().exec(hwdebug1);              
                } catch (IOException e) {
                }            

所以，如果我点击我的按钮，它会完美地工作，但如果我做了类似的事情，它就不会工作:

final String[] hwdebug1 = {"su","-c","echo hello > /system/hello1.txt","echo hello > /system/hello2.txt","echo hello > /system/hello3.txt"};

我的目的是让按钮执行多个命令。我已经通过让它执行 bash 脚本来做到这一点，但我更喜欢找到一种将其放在代码中的方法。

谢谢!

用Ben75方法解决

final String[] hwdebug1 = {"su","-c","echo hello > /system/hello1.txt"};
final String[] hwdebug2 = {"su","-c","echo hello > /system/hello2.txt"};
final String[] hwdebug3 = {"su","-c","echo hello > /system/hello3.txt"};
ArrayList<String[]> cmds = new ArrayList<String[]>();
cmds.add(hwdebug1);
cmds.add(hwdebug2);
cmds.add(hwdebug3);
for(String[] cmd:cmds){
    try {
       Runtime.getRuntime().exec(cmd);              
   } catch (IOException e) {
       e.printStacktrace(); 
   }          
}

Runtime.exec 命令适用于单个命令，不是 cmd 行字符串的简单“包装器”。

只需创建一个列表并对其进行迭代即可:

final String[] hwdebug1 = {"su","-c","echo hello > /system/hello1.txt"};
final String[] hwdebug2 = {"su","-c","echo hello > /system/hello2.txt"};
final String[] hwdebug3 = {"su","-c","echo hello > /system/hello3.txt"};
ArrayList<String[]> cmds = new ArrayList<String[]>();
cmds.add(hwdebug1);
cmds.add(hwdebug2);
cmds.add(hwdebug3);
for(String[] cmd:cmds){
    try {
       Runtime.getRuntime().exec(cmd);              
   } catch (IOException e) {
       e.printStacktrace(); 
   }          
}
