我有以下代码用来执行root的命令:变量的内部类中访问
public static String sudo(final String cmd, Context ctx) {
String output = null; //init string output
if (RootTools.isRootAvailable()) {
if (RootTools.isAccessGiven()) {
try {
CommandCapture command = new CommandCapture(0, cmd) {
@Override
public void output(int id, String line) {
Log.d("com.vwade79.aokpdelta.Functions.sudo", "cmd:"+cmd+"\noutput:"+line);
if (line.equals("")) {
return;
}
else {
output = line; //ERROR
}
}
};
RootTools.getShell(true).add(command).waitForFinish();
} catch (Exception e) {
Toast.makeText(ctx, "There was an error executing root command : "+cmd, Toast.LENGTH_LONG).show();
e.printStackTrace();
}
}
else {
Toast.makeText(ctx, "Root permission isn't given!", Toast.LENGTH_LONG).show();
Intent intent = new Intent(ctx, MainActivity.class);
ctx.startActivity(intent);
}
}
else {
Toast.makeText(ctx, "You're not rooted! Come back when you are!", Toast.LENGTH_LONG).show();
Intent intent = new Intent(ctx, MainActivity.class);
ctx.startActivity(intent);
}
return output;
}
我得到一个错误:
variable "output" is accessed from within inner class. Needs to be declared final.
我不知道如何分配来自“内部阶层”的输出。
哦,谢谢,我想到了,但认为最终会让它变得不可改变哈哈。 –
