我有TextWatcher的代码，它使用2个不同的ArrayAdapter更改了2个不同的listView。
private TextWatcher createAndReturnTextWatcher()
{
final List<String> list = dbExtractor.getDataForSearchAdapters();
adapterForSearch = new MyAdapter(this, R.layout.list_item2, R.id.product_name,
list);
adapter = new ArrayAdapter(this, R.layout.list_item2, R.id.product_name,
dbExtractor.getDataForSearchAdapters());
TextWatcher watcher1;
watcher1 = new TextWatcher() {
@Override
public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3) {
if (cs.length() == 0) {
lv.setAdapter(null);
lv2.setAdapter(null);
dc.clickedOnce = true;
dc.decrement();
dc.checkDimCounter();
} else {
lv.setAdapter(adapterForSearch);
adapterForSearch.getFilter().filter(cs);
lv2.setAdapter(adapter);
adapter.getFilter().filter(cs);
if (dc.clickedOnce) {
dc.increment();
dc.checkDimCounter();
dc.clickedOnce = false;
}
}
}
@Override
public void beforeTextChanged(CharSequence arg0, int arg1, int arg2,
int arg3) {
}
@Override
public void afterTextChanged(Editable arg0) {
}
};
return watcher1;
}
问题是：
当我使用一个标准的ArrayAdapter类和一个自定义的ArrayAdapter类时，为什么这个工作正常，但是如果我尝试使用两个自定义ArrayAdapter它就不起作用。这只是改变了两个listView，就像它们都使用一个自定义适配器一样？
提前致谢！
MY CUSTOM ADAPTERS
第一
公共类MyTurkishAdapter扩展了ArrayAdapter {
protected Filter myTurkFilter;
protected List<String> mObjects;
protected List<String> mOriginalValues;
public MyTurkishAdapter(Context context, int resource, int textViewResourceId, List objects) {
super(context, resource, textViewResourceId, objects);
myTurkFilter = new MyTurkFilter();
mObjects = objects;
}
@Override
public Filter getFilter() {
return myTurkFilter;
}
private class MyTurkFilter extends Filter
{
@Override
protected FilterResults performFiltering(CharSequence prefix) {
FilterResults results = new FilterResults();
if (mOriginalValues == null) {
{
mOriginalValues = new ArrayList<String>(mObjects);
}
}
if (prefix == null || prefix.length() == 0) {
ArrayList<String> list;
{
list = new ArrayList<>(mOriginalValues);
}
results.values = list;
results.count = list.size();
} else {
java.lang.String prefixString = prefix.toString().toLowerCase();
ArrayList<String> values;
{
values = new ArrayList<>(mOriginalValues);
}
final int count = values.size();
final ArrayList<String> newValues = new ArrayList<String>();
for (int i = 0; i < count; i++) {
final String value = values.get(i);
final java.lang.String valueText = value.toLowerCase();
if (valueText.startsWith(prefixString)) {
newValues.add(reverse(value));
}
}
results.values = newValues;
results.count = newValues.size();
}
return results;
}
@Override
protected void publishResults(CharSequence constraint, FilterResults results) {
mObjects.clear();
mObjects.addAll((List<String>) results.values);
if (results.count > 0) {
notifyDataSetChanged();
} else {
notifyDataSetInvalidated();
}
}
}
private java.lang.String reverse(java.lang.String couples)
{
java.lang.String[] arr = couples.split(" — ");
return arr[1]+ " — " + arr[0];
}
}
第二
public class MyAdapter extends ArrayAdapter {
protected Filter filter;
protected List<String> mObjects;
protected List<String> mOriginalValues;
public MyAdapter(Context context, int resource, int textViewResourceId, List<String> objects) {
super(context, resource, textViewResourceId, objects);
filter = new MyFilter();
mObjects = objects;
}
@Override
public Filter getFilter() {
return filter;
}
private class MyFilter extends Filter
{
@Override
protected FilterResults performFiltering(CharSequence prefix) {
FilterResults results = new FilterResults();
if (mOriginalValues == null) {
{
mOriginalValues = new ArrayList<String>(mObjects);
}
}
if (prefix == null || prefix.length() == 0) {
ArrayList<String> list;
{
list = new ArrayList<String>(mOriginalValues);
}
results.values = list;
results.count = list.size();
} else {
java.lang.String prefixString = prefix.toString().toLowerCase();
ArrayList<String> values;
{
values = new ArrayList<String>(mOriginalValues);
}
final int count = values.size();
final ArrayList<String> newValues = new ArrayList<String>();
//DictionaryActivity2.turkish.clear();
for (int i = 0; i < count; i++) {
final String value = values.get(i);
final java.lang.String valueText = value.toString().toLowerCase();
if (valueText.startsWith(prefixString)) {
newValues.add(value);
}
}
results.values = newValues;
results.count = newValues.size();
}
return results;
}
@Override
protected void publishResults(CharSequence constraint, FilterResults results) {
mObjects.clear();
mObjects.addAll((List<String>) results.values);
if (results.count > 0) {
notifyDataSetChanged();
} else {
notifyDataSetInvalidated();
}
}
}
}
P.S。他们只有一个线差异。我知道模板方法模式，并在我找到这个问题的答案之后立即实现：）
