listView onclick活动

Question

我有一个listView，其中包含一些来自服务器的数据。每次按下其中一个列表项时，我都想进行一项活动。有什么想法吗？

public void Status1() {
        setContentView(R.layout.status);
        update = (Button) findViewById(R.id.update);
        refresh = (Button) findViewById(R.id.refresh);

        update.setOnClickListener(update_btn);
        refresh.setOnClickListener(refresh_btn);

        lv1 = (ListView) findViewById(R.id.ListView);

        // By using setAdpater method in listview we an add string array in
        // list.

        lv1.setAdapter(new ArrayAdapter<String>(this,
                android.R.layout.simple_list_item_1, lv_arr));

         lv.setOnItemClickListener(new OnItemClickListener() {
                public void onItemClick(AdapterView<?> parent, View view,
                    int position, long id) {
                  // When clicked, show a toast with the TextView text
                  Toast.makeText(getApplicationContext(), ((TextView) view).getText(),
                      Toast.LENGTH_SHORT).show();
                }
              });

        final EditText username2 = (EditText) findViewById(R.id.username1);
        //String a = username1.getText().toString();

        //username2.setText(a);
        username2.setOnKeyListener(new OnKeyListener() {
            public boolean onKey(View v, int keyCode, KeyEvent event) {
                // If the event is a key-down event on the "enter" button
                if ((event.getAction() == KeyEvent.ACTION_DOWN)
                        && (keyCode == KeyEvent.KEYCODE_ENTER)) {
                    // Perform action on key press
                    // Editable a=findViewById(R.id.username).getText();
                    // username2.setText(a);

                    Toast.makeText(yassou.this, username2.getText(),
                            Toast.LENGTH_SHORT).show();
                    return true;
                }
                return false;
            }
        });

    }

我试过这个：EDIT1

 lv1.setOnItemClickListener(new OnItemClickListener() {
                public void onItemClick(AdapterView<?> parent, View view,
                    int position, long id) {



                     startActivity(new Intent("com.example.HelloGoogleMaps2"));
                }
              });

和这：EDIT2

lv1.setOnItemClickListener(new OnItemClickListener() {
                public void onItemClick(AdapterView<?> parent, View view,
                    int position, long id) {
                  // When clicked, show a toast with the TextView text
                Intent myIntent = new Intent(view.getContext(), HelloGoogleMaps2.class);
                    startActivityForResult(myIntent, 0);


                }
              });

但没有人使用方法......请帮助!!

Answer 1

您可以附加intent和bundle作为listview的适配器的一部分。这会将适当的包传递给用户单击列表项时启动的活动。
