Question

我得到一个字符串[]数组并将其存储在一个String数组[变量mystrings]中，现在我希望这个数组在列表视图中显示它并带有复选框。

ec_checkbox_number.xml

<?xml version="1.0" encoding="utf-8"?>

CheckBoxData.java

public class CheckBoxData {

    private String[] number;

    public String[] getNumber() {
        return number;

    public void setNumber(String[] number) {
        this.number = number;
    }



}

MyConferenceNumber.java

public class EcConferenceNumber extends Activity{
    ListView checkBoxNumberListView;
    ConferenceAdapter adapter;
    Button doneBtn,cancelBtn;
    EditText profileName;
    MyCustomAdapter dataAdapter = null;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.ec_number_selection);   
        adapter = new ConferenceAdapter(this);
        checkBoxNumberListView = (ListView) findViewById(R.id.numberselectionlistView);

        Intent intent = getIntent();
        String[]  myStrings = intent.getStringArrayExtra("strings");

        List<String> strings = 
                 new ArrayList<String>(Arrays.asList(myStrings));

        System.out.println(""+strings);

        dataAdapter = new MyCustomAdapter(this,
                R.layout.ec_checkbox_number, strings);
        checkBoxNumberListView.setAdapter(dataAdapter);

        checkBoxNumberListView.setOnItemClickListener(new OnItemClickListener() {
               public void onItemClick(AdapterView parent, View view,
                 int position, long id) {
                // When clicked, show a toast with the TextView text
                CheckBoxData country = (CheckBoxData) parent.getItemAtPosition(position);
                Toast.makeText(getApplicationContext(),
                  "Clicked on Row: " + country.getNumber(),
                  Toast.LENGTH_LONG).show();
               }
              });

    }
    class MyCustomAdapter extends ArrayAdapter<String>{

        private List<String> strings;

        public MyCustomAdapter(Context context, int textViewResourceId, List<String> strings) {
            super(context, textViewResourceId,strings);
            this.strings=new ArrayList<String>();
            this.strings.addAll(this.strings);

            // TODO Auto-generated constructor stub
        }

        private class ViewHolder {
               TextView code;
               CheckBox name;
              }
        @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)getSystemService(
             Context.LAYOUT_INFLATER_SERVICE);
           convertView = vi.inflate(R.layout.ec_checkbox_number, null);

           holder = new ViewHolder();
           holder.code = (TextView) convertView.findViewById(R.id.checkboxtextView);
           holder.name = (CheckBox) convertView.findViewById(R.id.checkBox);
           convertView.setTag(holder);

            holder.name.setOnClickListener( new View.OnClickListener() { 
             public void onClick(View v) { 
              CheckBox cb = (CheckBox) v ; 
              CheckBoxData country = (CheckBoxData) cb.getTag(); 
              Toast.makeText(getApplicationContext(),
               "Clicked on Checkbox: " + cb.getText() +
               " is " + cb.isChecked(),
               Toast.LENGTH_LONG).show();

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



           return convertView;

          }

         }

    }

我得到的输出是......

例如：如果String [] a = {002,111,122}我想在带有复选框的列表视图中显示它，我必须得到所选的CheckBox文本。但是我的输出是这样的

号码

但我希望输出像这样，

123

112

123

因为，我是android的新手，我不知道如何将数组设置为输出视图。任何答案都会有所帮助。

Answer 1

粘贴完整的xml代码。 xml中没有按钮，缺少一些属性。

如何在android列表视图中使用复选框将字符串数组设置为数组适配器？
