Question

有人能给我一个On item click侦听器的例子，用于带有基础适配器的列表视图吗？

我的列表视图包含两个文本视图和一个复选框。我想创建一个on item click侦听器，这样当按下一个项目（或行）时，它会勾选相应的行复选框。

我尝试过谷歌，但找不到任何关于它的例子

谢谢

所以，适配器并不重要，但我相信你要做的事情非常简单，首先你需要得到ListView的参考，我将其称为listView

设置适配器后，您可以使用setOnItemClickListener创建点击操作

    listView.setAdapter(adapter);
    listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public boolean onItemClick(AdapterView<?> parent, View view, int position, long id) {
            //here you can use the position to determine what checkbox to check
            //this assumes that you have an array of your checkboxes as well. called checkbox
            checkBox[position].setChecked(!checkBox.isChecked());
        }
    });

实际上很简单，执行动作“setAdapter”后你必须这样做：

list.setOnItemClickListener(new AdapterView.OnItemClickListener() {

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

Toast.makeText(getApplicationContext(), "You click on position:"+position, Toast.LENGTH_SHORT).show();

        }
    });

Answer 3

以下代码正常运行：

list.setOnItemClickListener(new AdapterView.OnItemClickListener() {

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

    Toast.makeText(getApplicationContext(), 
                   "You click on position:"+position, Toast.LENGTH_SHORT).show();
  }
});

但是当我点击items时，它会进入其他活动。我该怎么办？

您可以使用OnItemClick（）方法的View参数访问listview行的所有元素。例如

    listview.setOnItemClickListener(new AdapterView.OnItemClickListener() {

    @Override
    public void onItemClick(AdapterView<?> parent, 
                      View view, int position, long id) { 
    // second parameter View view entire row object that is clicked  - in your case 
    // two text views and the checkbox
    // supposing your checkbox is set up with an id in the xml as idchkbox
    // You can access it by findview by id and set it true or false;
        android.widget.CheckBox  chkbox = view.findViewbyId(R.id.idchkbox);
        chkbox.setChecked = true;
        return;
    });
