Question

所以目前我有一个列表视图，每行末尾都有复选框。现在，当你勾选方框时，方框会被勾选并且未被勾选。但我想要的是当你点击listview项目/行时，复选框被勾选或未勾选。

这是我的代码：

public class MyActivity3 extends Activity {
private TextView tv;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_my3);
    Button m = (Button) findViewById(R.id.button3);
    tv = (TextView) findViewById(R.id.textViewcat);
    Typeface typeface = Typeface.createFromAsset(getAssets(), "BebasNeue Bold.ttf");
    tv.setTypeface(typeface);


    String listArray[] = new String[] { "All", "Friends & Family", "Sports", "Outside",
            "At School", "Fitness", "Photography", "Food", "Beach", "Money" };
    ListView listView = (ListView) findViewById(R.id.listView);
    List<HashMap<String, String>> aList = new ArrayList<HashMap<String, String>>();
    for (int i = 0; i <= listArray.length - 1; i++) {
       HashMap<String, String> hm = new HashMap<String, String>();
        hm.put("title", listArray[i]);
        aList.add(hm);
    }
    String[] sfrm = { "title"};
    int[] sto = { R.id.title};
    SimpleAdapter adapter = new SimpleAdapter(getBaseContext(), aList,
            R.layout.row_layout, sfrm, sto);
   listView.setAdapter(adapter);
   listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> arg0, View view,
                                int position, long id) {
            switch (position) {

            }

        }
    });
}

Answer 1

    @Override
    public void onItemClick(AdapterView<?> arg0, View view,position, long id) {
    CheckBox cb = (CheckBox) view.findViewById(R.id.your_checkbox);    
    cb.setChecked(!cb.isChecked());
    }

如果不是，则只检查项目，如果是，则取消选中。

Zoltish的建议对你来说很好，但是如果你创建一个自定义列表适配器，那么对于每个新要求的列表和无错编码的进一步修改会更好

如果提到的教程太复杂，你可以试试这样的

private class checkBoxListAdapter extends BaseAdapter {




    private class ViewHolder {

        CheckBox chk;

    }


    @Override
    public View getView(int position, View convertView, ViewGroup parent) {

        ViewHolder holder = null;

        Log.v("ConvertView", String.valueOf(position));

        if (convertView == null) {

            LayoutInflater vi = (LayoutInflater) atvt
                    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

            convertView = vi.inflate(R.layout.msg_receipents, null);

            holder = new ViewHolder();

            holder.chk = (CheckBox) convertView
                    .findViewById(R.id.checkBox1);


            convertView.setTag(holder);

            convertView.setOnClickListener(new View.OnClickListener() {
                public void onClick(View v) {

                                            holder.chk.setChecked(!holder.chk.isChecked());
                }
            });

        } else {
            holder = (ViewHolder) convertView.getTag();


        }




        return convertView;
    }

}

单击列表项时勾选或取消选中复选框
