Question

我正在尝试将数据从createCheckboxList方法传递到getLRL类，但是当我尝试在post_selected GetLRL类中调用getIntent时，我收到此错误The method getIntent() is undefined for the type GetLRL

我该如何解决？

MainActivity中的createCheckboxList：

private void createCheckboxList(final ArrayList<Integer> items) {
        this.items = items;
        final ArrayList<Integer> selected = new ArrayList<Integer>();
        ...

            btn.setOnClickListener(new View.OnClickListener() {

                @Override
                public void onClick(View v) {       
                    Intent intent = new Intent(MainActivity.this, GetLRL.class);
                    intent.putIntegerArrayListExtra("selected_route", selected);
                    startActivity(intent);
        }
    }

GetLRL中的post_selected方法：

public void post_selected() {
//  here is the error
    Bundle extras = getIntent().getExtras();
    if (extras != null && extras.containsKey("selected_route")) {

        ArrayList<Integer> routeList = extras
                .getIntegerArrayList("selected_route");

    }

    //new MyAsyncTask(context).execute(jSONString);
}

GetLRL类必须是一个Activity（// Function to write a file in a non-existing directory function writeFile(path, contents, cb){ mkdirp(getDirName(path), function(err){ if (err) return cb(err); fs.writeFile(path, contents, cb); }); } // Check if log file exists, if it does not, then create it fs.exists(__dirname + '/log/access.log', function(exists){ if(exists){ app.use(logger('common', { stream: fs.createWriteStream(__dirname + '/log/access.log', {flags: 'a'}) })); console.log('access.log exists!'); } else { writeFile(__dirname + '/log/access.log', {flag: 'wx'}, function(err){ if (err) throw err; console.log('access.log created!'); }); } });），如果不是，那么将抛出未定义的方法异常

对于GetLRL
