android - 实现自定义列表视图的复选框

Question

我已经编写了代码以从数据库中获取值并将该值绑定到列表视图。为此，我现在根据要求使用了自定义列表视图，我想要列表中每个项目的复选框。如何做到这一点

image=(ImageView)findViewById(R.id.image);
        note=(ImageButton)findViewById(R.id.note);
        tick=(ImageButton)findViewById(R.id.tick);
        cross=(ImageButton)findViewById(R.id.cross);
        Intent intent = getIntent();
        Bitmap photo = (Bitmap) intent.getParcelableExtra("photooo");
        image.setImageBitmap(photo);
        if(photo!=null)
        {
            dbHelper = new RecordsDbAdapter(this);
            dbHelper.open();
            displayListView();
        }

    }
    private void displayListView() {
        Cursor cursor = dbHelper.fetchAllRecords();
        String[] columns = new String[] {
                RecordsDbAdapter.KEY_NAME,
                RecordsDbAdapter.KEY_BIRTHDAY,

        };
        int[] to = new int[] {
                R.id.name,
                R.id.birthdate,
        };
        dataAdapter = new SimpleCursorAdapter(
                this, R.layout.row,
                cursor,
                columns,
                to);
        ListView listView = (ListView) findViewById(R.id.list);
        listView.setAdapter(dataAdapter);
    }
}

Answer 1

• 使用 LayoutInflater 将复选框添加到列表视图
• 使用 SetTag 方法后将 Tagvalue 添加到复选框
• 下面的代码示例列表视图中每个项目中的此标记值单独复选框：`

LayoutInflater inflater = getLayoutInflater();

 convertView = inflater.inflate(R.layout.home1, null);

ViewHolder holder1 = new ViewHolder(); holder1.text = (TextView) convertView.findViewById(R.id.textView1);

   holder1.ch=(CheckBox)convertView.findViewById(R.id.checkBox1);
  holder1.ch .setTag(position);

Answer 2

就像您之前所做的那样，转到 R.layout.row 的 XML 文件并输入以下代码：

<CheckBox
    android:id="@+id/checkbox"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerVertical="true"
    android:text="checkbox" />

然后像这样编辑您的代码：-

    private void displayListView() {
    Cursor cursor = dbHelper.fetchAllRecords();
    String[] columns = new String[] {
            RecordsDbAdapter.KEY_NAME,
            RecordsDbAdapter.KEY_BIRTHDAY,
            RecordsDbAdapter.KEY_CHECKBOX

    };
    int[] to = new int[] {
            R.id.name,
            R.id.birthdate,
            R.id.checkbox
    };
    dataAdapter = new SimpleCursorAdapter(
            this, R.layout.row,
            cursor,
            columns,
            to);
    ListView listView = (ListView) findViewById(R.id.list);
    listView.setAdapter(dataAdapter);
}
