Hi I am working with android.I had created a listview using array list. Now how can I add Action to each list item and also how to get the list position of that item. Please help me, thanks

这是我的代码

        public class MainActivity extends Activity {


          private ListView lv;

     @Override
      protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        ListView lv=(ListView)findViewById(R.id.listView1);
        ArrayList<String> list=new ArrayList<String>();
        list.add("aaaa");
        list.add("bbbb");
        list.add("cccc");
        list.add("dddd");

         ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(
                this, 
               android.R.layout.simple_list_item_1,
              list);
        lv.setAdapter(arrayAdapter); 


        }


     }

推荐答案

您需要实现ListView setOnItemClickListener

listview.setOnItemClickListener(new AdapterView.OnItemClickListener() {

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

       // ListView Clicked item index
               int itemPosition     = position;

               // ListView Clicked item value
               String  itemValue    = (String) listView.getItemAtPosition(position);

                // Show Alert 
                Toast.makeText(getApplicationContext(),
                  "Position :"+itemPosition+"  ListItem : " +itemValue , Toast.LENGTH_LONG)
                  .show();
    }
        });
