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List,我想在各自的点击上调用相应的活动,比如用户点击转移然后它会显示转移活动,如何在此列表上调用onClickListener以及如何在点击时启动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] );
            }

        });

有两个选项可以处理每行的click事件.

1)如果您的类扩展ListActivity,您可以覆盖以下方法.

@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)处理getView()方法中的行的单击事件

row.setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(View v) {

    }
});

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);
            }
          });
