android - 包含编辑文本的 ListView

Question

我有一个 ListView ，它的行由一些编辑文本组成。我的问题是它的值在滚动时自动改变。我尝试了很多方法，但都不起作用。有没有与此相关的例子？任何人都请帮助我

public class MainActivity extends Activity {

private ListView myList;
private CustomAdapter myAdapter;
Context context;
private String[] guess = new String[20];

ArrayList<String> list_id = new ArrayList<String>();

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    for(int i=0;i<19;i++){
        list_id.add(""+i);
        guess[i] = i+"";
    }

    myList = (ListView) findViewById(R.id.listView1);
    myList.setItemsCanFocus(true);

    initList();
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.activity_main, menu);
    return true;
}
public void initList()
{
    ArrayAdapter<String> listAdapter = new ArrayAdapter<String>(this, R.id.textView1, guess)
    {

        @Override
        public View getView(final int position, View convertView, ViewGroup parent)
        {
            if (convertView == null)
            {
                convertView = LayoutInflater.from(getContext()).inflate(R.layout.row, null);
            }

            final String theData = getItem(position);
            final EditText editText = (EditText) convertView.findViewById(R.id.editText1);
            //editText.setText(theData);
            editText.setText(guess[position]);
            editText.addTextChangedListener(
                    new MyTextWatcher(position)
                    );

            return convertView;
        }
        };

        myList.setAdapter(listAdapter);
}

class MyTextWatcher implements TextWatcher {
    private int position;

    public MyTextWatcher(int position) {
        this.position = position;
    }

    public void afterTextChanged(Editable s) {
        guess[position] = s.toString();
    }

    @Override
    public void beforeTextChanged(CharSequence s, int start, int count,
            int after) {
        // TODO Auto-generated method stub

    }

    @Override
    public void onTextChanged(CharSequence s, int start, int before,
            int count) {
        // TODO Auto-generated method stub

    }

    // other methods are created, but empty
}

}

Answer 1

最后我自己解决了这个问题。问题是因为我的 xml 文件。对于每一行，我都使用了两个编辑文本，一个输入类型为“numberDecimal”，另一个输入类型为“text”。有问题。当我将两种输入类型都更改为“NumberDecimal”时，它起作用了。我不知道为什么。为了输入文本，我将其中一种编辑文本输入类型更改为“textvisiblepassword”。
