Question

当只检查1时，CheckedTextView显示多个已检查项目是否还有其他问题？单击CheckedTexView项时，OnClickListener的响应是检查单击项之前和之后的条目。

以下是代码：

    mFriendDoneButton = (Button) findViewById(R.id.doneAddAFriendButton);
    mListView = (ListView)findViewById(R.id.contactList);

    populateContactList();

    mListView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
    mListView.setItemsCanFocus(false);

    mListView.setOnItemClickListener(
            new AdapterView.OnItemClickListener() {
          @Override
          public void onItemClick(AdapterView<?> adapterView, View view,
              int arg2, long arg3) {
            int selectedPosition = arg2;

            CheckedTextView textView = (CheckedTextView)view.findViewById(R.id.friendEntryText);
            String mtext = textView.getText().toString();


            Log.i("AddAFriendActivity", "Click on position "+selectedPosition);

            Toast t = new Toast(AddAFriendActivity.this);
            t = Toast.makeText(AddAFriendActivity.this, "Clicked on  " + arg2+mtext+arg3, Toast.LENGTH_LONG);
            t.show();

          }
        });

private void populateContactList（）{ //使用联系人条目构建适配器游标光标= getContacts（）; String [] fields = new String [] { ContactsContract.Data.DISPLAY_NAME }; SimpleCursorAdapter adapter = new SimpleCursorAdapter（this，R.layout.friend_entry，cursor，fields，new int [] {R.id.friendEntryText}）; mListView.setAdapter（适配器）; }

private Cursor getContacts()
{
    // Run query
    Uri uri = ContactsContract.Contacts.CONTENT_URI;

    String[] projection = new String[] {
            ContactsContract.Contacts._ID,
            ContactsContract.Contacts.DISPLAY_NAME
    };
    String selection = null;
    String[] selectionArgs = null;
    String sortOrder = null;

    return managedQuery(uri, projection, selection, selectionArgs, sortOrder);
}

XML如下：

Answer 1

发现问题... textView需要声明为字段，否则managedQuery结果循环通过onClickListener。

CheckedTextView表现不正常
