Java 显示来自其他活动的Arraylist的listview

我想制作本地高分表，并在主要活动中展示。 我构建了一个

ListView

和

ArrayAdapter

等等。 当我打开包含列表视图的意图时，我看不到列表视图，我在应用程序代码中得到一些位置作为文本视图。（见图）

代码： 具有

Arraylist的Person类

public class Person extends Activity {
    EditText name;
    Button ok;
    TextView enter;
    Integer Score;
    String Name;
    Person person;
    ArrayList<Person> TopTen = new ArrayList<Person>(10);

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_person);

        Intent intent = getIntent();
        Score = intent.getIntExtra("Score", 0);//defualt value if thers no score
        name = (EditText) findViewById(R.id.namep);
        ok = (Button) findViewById(R.id.send);
        enter = (TextView) findViewById(R.id.entername);
        Toast toast = Toast.makeText(getApplicationContext(), "Lets see if you are can be on TopTen", Toast.LENGTH_SHORT);
        person = new Person();
        person.Name = name.getText().toString();
        person.Score = Score;
        ok.setOnClickListener(SendActionListener);
    }

    private OnClickListener SendActionListener = new OnClickListener() {
        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            // error is here
            /*Person lastEntry = TopTen.get(TopTen.size()-1);//Last element of the arraylist
            Log.d("TopTen", lastEntry.Score.toString());
            if(lastEntry.Score < Score){//checking score
                lastEntry.Score = Score;//put score aka Value
                lastEntry.Name=name.getText().toString();//put name aka Key
                Toast toast = Toast.makeText(getApplicationContext(), "You are now on the TopTen List", Toast.LENGTH_SHORT);
            }*/
            /*Iterator<Person> iterator = TopTen.iterator();
            while(iterator.hasNext()){
                if(!iterator.hasNext()){//last value of the list

                }

            }*/
            int size = TopTen.size() - 1;
            Log.d("size", String.valueOf(size));
            if (size == -1) {//No Values in the array
                TopTen.add(person);
            } else {
                size = TopTen.size() - 1;
                if (person.Score > 0) {
                    if (TopTen.get(size).Score < person.Score) {
                        TopTen.remove(size);
                        TopTen.add(person);
                        Toast toast = Toast.makeText(getApplicationContext(), "You are in topten", Toast.LENGTH_SHORT);
                        toast.show();
                        Intent intent = new Intent(Person.this, MainActivity.class);
                        //intent.putExtra("ArrayList", TopTen);
                        startActivity(intent);
                    } else {
                        Toast toast = Toast.makeText(getApplicationContext(), "You are not in topten", Toast.LENGTH_SHORT);
                        toast.show();
                        Intent intent = new Intent(Person.this, MainActivity.class);
                        //intent.putExtra("ArrayList", TopTen);
                        startActivity(intent);
                    }
                }
            }
            //Collections.sort(TopTen, new ScoreComparator());
        }
    };

    public Integer getScore() {
        return Score;
    }

    class ScoreComparator implements Comparator<Person> {
        @Override
        public int compare(Person person1, Person person2) {
            // TODO Auto-generated method stub
            return person1.getScore().compareTo(person2.getScore());
        }

    }

}//end of Person

将列表数组作为可解析包传递，或者只将对象列表从一个活动传递到第二个活动
切勿在适配器中引用活动。你必须以另一种方式传递你的前十名ArrayList。显然，你应该做的是做一个Android教程，向你解释Android的一般工作原理，比如这家伙的视频：一旦你知道如何不手动实例化活动，并且有专门的类来存储你显示的数据，而不是合并你的数据“个人”（数据）和活动（数据显示），最重要的是，当你知道你在做什么时，你应该清理你写的东西并重新做。我会尽快重新做。这是真的，这里真正的问题是他的“列表数组”由活动组成。
