【问题描述】：

我有这个 simpleList 视图，我想为每个复选框创建不同的侦听器。

在 OnItemClick 函数上，我有 toast 消息，但我根本看不到它（如果我从布局 xml 中删除复选框，我可以看到 toast...）

我的代码：

public class MainActivity extends ActionBarActivity 
    ListView myList;
    List<Student> data;
    CustomAdapter adapter;
    @Override
    protected void onCreate(Bundle savedInstanceState) 
        super.onCreate(savedInstanceState);
        setContentView(R.layout.student_list);

        data = Model.getInstance().getAllStudents();
        myList = (ListView) findViewById(R.id.listView);

        adapter = new CustomAdapter();
        myList.setAdapter(adapter);

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


                Toast.makeText(getApplicationContext(),"item click " + position,Toast.LENGTH_LONG).show();
                Intent intent = new Intent(getApplicationContext(),StudentDetailsActivity.class);
                intent.putExtra("id",data.get(position).id);
                startActivity(intent);
            
        );

    

    @Override
    public void onResume()
        super.onResume();
        adapter.notifyDataSetChanged();

    
    @Override
    public boolean onCreateOptionsMenu(Menu menu) 
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_main, menu);
        return true;
    

    @Override
    public boolean onOptionsItemSelected(MenuItem item) 
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in androidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) 
            return true;
        

        return super.onOptionsItemSelected(item);
    

    class CustomAdapter extends BaseAdapter

        @Override
        public int getCount() 
            return data.size();
        

        @Override
        public Object getItem(int position) 
            return data.get(position);
        

        @Override
        public long getItemId(int position) 
            return position;
        

        @Override
        public View getView(int position, View convertView, ViewGroup parent) 
            if(convertView == null)
                LayoutInflater inflater = getLayoutInflater();
                convertView = inflater.inflate(R.layout.rows_student_list,null);
            

            ImageView image = (ImageView) convertView.findViewById(R.id.imageView);
            TextView name = (TextView) convertView.findViewById(R.id.nameTextView);
            TextView id = (TextView) convertView.findViewById(R.id.idTextView);
            CheckBox checkBox=(CheckBox) convertView.findViewById(R.id.checkBox);
            Student st = data.get(position);

            name.setText(st.name);
            id.setText(st.id);
            checkBox.setTag(Integer.valueOf(position));

            return convertView;
        
    

我该怎么做？

【问题讨论】：

请发布您的布局 xml。

试试onItemSelected而不是onItemClick

这是我的完整代码：link onItemSelected 不能解决我的问题。

【参考方案1】：

在 XML 布局中将 CheckBox 设置为 focusable="false"。
