我有以下ListView 并希望仅显示在另一个活动中单击的项目。

public class MyActivity extends ActionBarActivity {
    private List<Madaxda> madaxdu = new ArrayList<Madaxda>();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_my);
        MadaxList();
        MadaxListView();
        RegisterCallBack();

    }

    private void MadaxList() {
        madaxdu.add(new Madaxda("Hassan Sheik","Madaxweyne","MSC", 2, R.drawable.hassan));
        madaxdu.add(new Madaxda("Awali Sheik","Raysal wasaare","Doctor", 2, R.drawable.awali));

    }

    private void MadaxListView() {
        ArrayAdapter<Madaxda> adapter = new MyListAdapters();
        ListView list = (ListView) findViewById(R.id.madaxdaListView);
        list.setAdapter(adapter);
    }
    private void RegisterCallBack() {
        ListView list = (ListView)findViewById(R.id.madaxdaListView);
        list.setOnItemClickListener(new AdapterView.OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView<?> parent, View viewClicked,
                                    int position, long id) {

                Intent intent = new Intent(MyActivity.this, Profile.class);
                intent.putExtra("position", position);
                startActivity(intent);
                //String message = "You have clicked Mudanaha  " +  position +
                     //   "oo magaciisu yahay " + m.getName() + "oo shaqadiisu tahay  "
                     //  + m.getBooska();
               // Toast.makeText(MyActivity.this,message,Toast.LENGTH_SHORT).show();

            }
        });

    }

    private class MyListAdapters extends ArrayAdapter<Madaxda> {
        MyListAdapters() {
            super(MyActivity.this, R.layout.lists, madaxdu);
        }

        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
            View itemView = convertView;
            if (itemView == null) {
                itemView = getLayoutInflater().inflate(R.layout.lists, parent, false);
            }
            Madaxda m = madaxdu.get(position);
            ImageView img = (ImageView) itemView.findViewById(R.id.item_icon);
            img.setImageResource(m.getID());
            TextView magaca = (TextView) itemView.findViewById(R.id.magaca_qofka);
            magaca.setText(m.getName());
            TextView shaqo = (TextView) itemView.findViewById(R.id.shaqada_qofka);
            shaqo.setText(m.getBooska());
            TextView sano = (TextView) itemView.findViewById(R.id.inta_sano);
            sano.setText("" + m.getYearsInService());
            TextView edu = (TextView) itemView.findViewById(R.id.education);
            edu.setText(m.getEducation());

            return itemView;


        }

    }

}

Answer 1

您似乎是在捆绑一个 int，但在拆分一个字符串。

试试这条线：

int position = getIntent().getInt("position");

Answer 2

如果我是你，我会尝试查看我收到的数据类型。理论上你应该得到一个 int 但安全的方法是通过调用 getIntent().getExtras() 来获取内部的 Bundle 然后接下来你尝试通过调用 getInt("position") 或 get("position") 来查看是否收到了你想要的想要。
如果 Bundle 为空，那么很明显你什么都没有。
