I got following exception from one of my app user in crash logs. Unable to understand from the log trace. If anybody has some thoughts, please share.

我通过添加这样的自定义侦听器来修复此错误：

protected class MyScrollListener implements OnScrollListener {

        @Override
        public void onScroll(AbsListView view, int firstVisibleItem,
                int visibleItemCount, int totalItemCount) {
            // do nothing 
        }

        @Override
        public void onScrollStateChanged(AbsListView view, int scrollState) {
            if (SCROLL_STATE_TOUCH_SCROLL == scrollState) {
                View currentFocus = getCurrentFocus();
                if (currentFocus != null) {
                    currentFocus.clearFocus();
                }
            }
        }

    }

然后使用您创建的侦听器：

listview.setOnScrollListener(MyScrollListener);

我尝试调用 EditText 小部件的 clearFocus() 成员，但这对我不起作用。然而，真正起作用的是调用父级的 clearChildFocus(View) 函数。这是代码：

ViewParent parent = mEditText.getParent();
parent.clearChildFocus(mEditText);

这对我有用。

convertView = mInflater.inflate(R.layout.row_stat_header,
                    parent, false);

这里，parent就是getView中的ViewGroup参数。

当我尝试将edittext与recyclerview一起使用时，我遇到了同样的错误。我认为这同样适用于使用 listview 的 editext。

当 Viewgroup 处理视图时出现焦点不匹配时会出现问题。对我来说，解决问题的方法是将 android:windowSoftInputMode="adjustPan" 添加到相关活动的清单中。

<activity android:name=".register.RegistrationActivity"
        android:windowSoftInputMode="adjustPan"/>

希望这对某人有用。
