問題描述

我正在編寫一個活動來列??出數據庫中的一堆項目并顯示一個帶有數量的附加列.我實現了一個 ArrayAdapter 來顯示我的自定義布局.下面是Adapter最重要部分的代碼:

I'm writing an activity to list a bunch of items from the database and show an additional column with a quantity. I implemented an ArrayAdapter to show my custom layout. Here is the code of the most important parts of the Adapter:

static class ViewHolder {
    protected TextView text;
    protected EditText editText;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    View view = null;
    if (convertView == null) {
        LayoutInflater inflator = context.getLayoutInflater();
        view = inflator.inflate(R.layout.rowquantitylayout, null);
        final ViewHolder viewHolder = new ViewHolder();
        viewHolder.text = (TextView) view.findViewById(R.id.label);
        viewHolder.editText = (EditText) view.findViewById(R.id.editText);
        viewHolder.editText.addTextChangedListener(new TextWatcher() {
            public void afterTextChanged(Editable s) {
                Log.i(TAG, "Editable:" + s.toString());
            }

            public void beforeTextChanged(CharSequence s, int start,
                    int count, int after) {
            }

            public void onTextChanged(CharSequence s, int start,
                    int before, int count) {
            }
        });
        view.setTag(viewHolder);
        viewHolder.editText.setTag(list.get(position));
    } else {
        view = convertView;
        ((ViewHolder) view.getTag()).editText.setTag(list.get(position));
    }
    ViewHolder holder = (ViewHolder) view.getTag();
    holder.text.setText(list.get(position).getDescription());
    holder.editText.setText("" + list.get(position).getQuantity());
    return view;

}

現在，當我嘗試聚焦EditText"時，它會在我單擊它后失去焦點.它顯示了 keboard，它甚至到達了 Log.i，但由于它沒有聚焦，所以不允許我更改值.

Now, when I try to focus the "EditText" it loses focus just after I clicked it. It shows the keboard and it even gets to the Log.i, but doesnt let me change the value since it is not focused.

感謝您的幫助

I had the same problem and I searched for an answer. Here is an answer to a similar question : https://stackoverflow.com/a/9338694/1448661

您必須在清單中的活動中添加一行:

You have to put a line in your activity in the manifest :

    android:windowSoftInputMode="adjustPan"

你的列表視圖也必須有這一行:

And your listview must have this line too :

    android:descendantFocusability="beforeDescendants"

現在您可能會面臨另一個問題，即滾動時文本丟失.如果發生這種情況，請查看本教程:http://vikaskanani.wordpress.com/2011/07/27/android-focusable-edittext-inside-listview/

And now you will probably face another problem which is the lost of your text when scrolling. If this happens take a look at this tutorial : http://vikaskanani.wordpress.com/2011/07/27/android-focusable-edittext-inside-listview/
