我想在 listView 中搜索产品名称,但是在我在搜索文本字段中键入一些文本后,列表中没有显示任何内容。我没有使用 ArrayAdapter,但我使用的是 ResourceCursorAdapter。
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
helper = new ComicsData(this);
helper.open();
listSearch=(EditText)findViewById(R.id.inputSearch);
listSearch.addTextChangedListener(filterTextWatcher);
model = helper.getAllProduct(list);
startManagingCursor(model);
adapter=new ShoppingListAdapter(this, model);
listView.setAdapter(adapter);
}
private TextWatcher filterTextWatcher=new TextWatcher(){
public void afterTextChanged(Editable s) {
}
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
}
public void onTextChanged(CharSequence s, int start, int before,
int count) {
//String search=listSearch.getText().toString();
//int textLength=search.length();
adapter.getFilter().filter(s);
}
};
购物清单适配器
class ShoppingListAdapter extends ResourceCursorAdapter {
private final String CN = null;
public ShoppingListAdapter(Context context, Cursor c) {
super(context, R.layout.productrow, c);
// TODO Auto-generated constructor stub
}
@Override
public void bindView(View row, Context context, Cursor c) {
// TODO Auto-generated method stub
listName = (TextView) row.findViewById(R.id.produtName);
listName.setText(helper.getProductName(c));
有人知道我的错误吗?
