我希望有人有个主意，因为这个问题让我不在乎。
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，使用loadPhoneNumbers（）方法使用4个“view_contact_phone_element”默认视图（没有电话号码）夸大“frag_contact_info_add_linearLayout_items”布局：
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;
}
问题是上下滚动此片段3到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）
虽然我在三星GT-I9300，三星GT-I8190和LG E400等设备上没有任何问题。
有人在我的代码中看到我做错了吗？
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，我只需打开一个对话框，显示可以从用户中选择的不同标签。
我想滚动视图中的微调器可能会在某些设备上引起此类问题。
答案 0 :(得分：1)
你有StackOverflowException，我认为这是因为你将你的视图添加到LinearLayout，它试图为每个可见项调用android.view.ViewGroup.addFocusables（），所以你得到了StackOverflowException。 LinearLayout无法处理这么多可能的可见元素，它不适合大量的子视图。
我认为，您最好使用ListView而不是将您的视图添加到LinearLayout，也可以使用ViewHolder模式以获得更好的内存使用率和ListView的速度性能。
