输出位置时出现问题

Question

我看了看一些教程，然后跟随一个教程制作了一个应用程序来获取用户的位置，但是在写完它之后，我遇到了大约4个错误，其中有3个已修复。现在，该应用程序开始启动，但是它无法获取位置或无法输出。这是我的代码。当我按下按钮时，没有任何反应，它不会崩溃或发出错误，所以我无法弄清楚问题出在哪里。

    textView  = (TextView) findViewById(R.id.textView);

    locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
    locationListener = new LocationListener() {
        @Override

                textView.append("\n" +location.getLatitude() +""+location.getLongitude());
