如何在 ArrayAdapter 上设置 onClickListener？

Question

我正在上课，如下所示

// All necessary imports are here

public class More extends Activity {

    String[] MoreItems = { "Transfers", "Budgets", "Branches", "Tools", "News",
            "Customer Service", "Settings", "Help", "About" };

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.more_view);

        ListView moreListView = (ListView) findViewById(R.id.moreListView);
        MoreListAdapter listAdapter = new MoreListAdapter();
        moreListView.setAdapter(listAdapter);

        // accountsTypeListView.setOnItemClickListener(listClickListner);
    }

    class MoreListAdapter extends ArrayAdapter<String> {
        MoreListAdapter() {
            super(More.this, R.layout.list_item, MoreItems);
        }

        public View getView(int position, View convertView, ViewGroup parent) {
            View row;

            if (convertView == null) {
                LayoutInflater inflater = getLayoutInflater();
                row = inflater.inflate(R.layout.list_item, parent, false);
            } else {
                row = convertView;
            }
            TextView tv = (TextView) row.findViewById(R.id.textItem);

            tv.setText(getItem(position));

            return row;
        }
    }
}

它会生成列表，我想在各自的点击中调用各自的活动，比如如果用户点击传输然后它会显示传输活动， 如何在此列表上调用 onClickListener 以及如何在单击时启动 Activity。

Answer 1

你也可以这样做..

moreListView.setOnItemClickListener(new OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
        // TODO Auto-generated method stub
        Log.d("############","Items " + MoreItems[arg2] );
    }
});

Answer 2

有两个选项可以处理每一行的点击事件。

1）如果你的类扩展了

ListActivity

，你可以重写下面的方法。

@Override
protected void onListItemClick(ListView l, View v, int position, long id) {
  super.onListItemClick(l, v, position, id);
  //do something here using the position in the array
}

2）在

getView()

方法中处理行的点击事件

row.setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(View v) {

    }
});

Answer 3

例如：

ListView lv = getListView();
lv.setAdapter(listAdapter); 
lv.setOnItemClickListener(new OnItemClickListener() {
    public void onItemClick(AdapterView<?> parent, View view,int position, long id) {
        Intent i = new Intent(More.this, NextActvity.class);
        //If you wanna send any data to nextActicity.class you can use
        i.putExtra(String key, value.get(position));
        startActivity(i);
    }
});

Answer 4

您的“更多”类必须扩展 ListActivity 而不是 Activity，然后您可以覆盖 onListItemClick

@Override
protected void onListItemClick(ListView l, View v, int position, long id) {
    super.onListItemClick(l, v, position, id);
    //do something here using the position in the arrya
}

编辑： 忘了说，在您的布局中，您的 ListView 必须被调用：android:id="@android:id/list"
