我希望有人有一个想法，因为这个问题让我忘记了。
在我的应用程序中，我有一个 Activity，其中包含一个片段，用于将新联系人插入到具有以下布局的地址簿中：

名为“frag_contact_info_add_linearLayout_items”的 LinearLayout 是一种用于动态插入/删除具有电话号码详细信息的项目（视图）的布局。通过将视图膨胀到 LinearLayout 中来插入每个视图。
名为“view_contact_phone_element”的单个项目具有以下布局：
<?xml version="1.0" encoding="utf-8"?>

当调用 onActivityCreated 方法时，“frag_contact_info_add_linearLayout_items”布局使用 loadPhoneNumbers() 方法填充了 4 个“view_contact_phone_element”默认视图（没有电话号码）：
private void loadPhoneNumbers() {
View phoneNumberView = null;
mPhoneNumbersLayout.removeAllViews();
List<NgnPhoneNumber> sPhoneNumberItems = mNewContact.getPhoneNumbers();
for (NgnPhoneNumber item : sPhoneNumberItems) {
phoneNumberView = displayPhoneNumberItem(item);
}
}
private View displayPhoneNumberItem(final NgnPhoneNumber item) {
LayoutInflater lf = mActivity.getLayoutInflater();
View phoneItemView = lf.inflate(R.layout.view_contact_phone_element, null, false);
final ViewHolder viewHolder=new ViewHolder();
mPhoneNumbersLayout.setTag(viewHolder);
viewHolder.spinner=(Spinner)phoneItemView.findViewById(R.id.contact_phone_phoneNumberTypeSpinner);
ArrayAdapter<String> phoneNumberTypeAdapter=new ArrayAdapter<String>(getActivity(), R.layout.view_spinner, mPhoneNumberTypes);
phoneNumberTypeAdapter.setDropDownViewResource(R.drawable.spinner_text);
viewHolder.spinner.setAdapter(phoneNumberTypeAdapter);
viewHolder.spinner.setSelection(item.getPhoneType().ordinal());
viewHolder.spinner.setOnItemSelectedListener(new OnItemSelectedListener(){
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
item.setPhoneType(PhoneType.values()[position]);
}
public void onNothingSelected(AdapterView<?> parent) {
}
});
final TextView tvPhoneNumber = (TextView)phoneItemView.findViewById(R.id.contact_phone_textView_number);
tvPhoneNumber.setText(item.getNumber());
tvPhoneNumber.setOnTouchListener(new OnTouchListener() {
public boolean onTouch(View mView, MotionEvent mMotionEvent) {
Log.d(TAG, "onTouch(): motionEvent=" + mMotionEvent.toString());
if(mMotionEvent.getAction() == MotionEvent.ACTION_UP) {
((XTabFragContacts)mActivity).showPhoneNumberDialog(
mActivity.getClass().getCanonicalName(),
mNewContact,
item,
mActivity,
mHandler);
return false;
}
return true;
}
});
viewHolder.ivDelete = (ImageView)phoneItemView.findViewById(R.id.contact_phone_imageView_delete);
viewHolder.ivDelete.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View view) {
mNewContact.removePhoneNumber(item.getNumber());
loadPhoneNumbers();
}
});
RelativeLayout.LayoutParams rlParams = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
mPhoneNumbersLayout.addView(phoneItemView, rlParams);
return phoneItemView;
}
问题是上下滚动这个片段 3 或 4 次，会导致我的应用程序崩溃并显示以下日志：

请注意，我仅在某些设备上遇到此问题，例如：-三星 GT-S5660 和 GT-S6500（运行 Android 2.3.6）-华为 U8186（运行 Android 2.3.6）
虽然我对三星 GT-I9300、三星 GT-I8190 和 LG E400 等设备没有任何问题。
有人看到我在代码中做错了什么吗？
提前致谢。
更新：
我通过用一个简单的按钮替换“view_contact_phone_element”中的微调器来解决。单击按钮时，我只打开一个对话框，显示可以从用户中选择的不同标签。
我猜滚动视图中的微调器可能会在某些设备上导致此类问题。
