@Override  protected void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentView(R.layout.activity_main);    ListView listView = (ListView) this.findViewById(R.id.list);    UserAdapter adapter = new UserAdapter(this, R.layout.list_item);    adapter.add(new User(10, "小智", "男"));    adapter.add(new User(10, "小霞", "女"));    listView.setAdapter(adapter);  }  @Override  public boolean onCreateOptionsMenu(Menu menu) {    // Inflate the menu; this adds items to the action bar if it is present.    getMenuInflater().inflate(R.menu.main, menu);    return true;  }  class UserAdapter extends ArrayAdapter<User> {    private int mResourceId;    public UserAdapter(Context context, int textViewResourceId) {      super(context, textViewResourceId);      this.mResourceId = textViewResourceId;    }    @Override    public View getView(int position, View convertView, ViewGroup parent) {      User user = getItem(position);      LayoutInflater inflater = getLayoutInflater();      View view = inflater.inflate(mResourceId, null);      TextView nameText = (TextView) view.findViewById(R.id.name);      TextView ageText = (TextView) view.findViewById(R.id.age);      TextView sexText = (TextView) view.findViewById(R.id.sex);      nameText.setText(user.getName());      ageText.setText(user.getAge());      sexText.setText(user.getSex());      return view;    }  }  class User {    private int mAge;    private String mName;    private String mSex;    public User(int age, String name, String sex) {      this.mAge = age;      this.mName = name;      this.mSex = sex;    }    public String getName() {      return this.mName;    }    public String getAge() {      return this.mAge + "";    }    public String getSex() {      return this.mSex;    }  }
