我无法从数组中获取数据,然后在搜索框中搜索数据。它只显示一个结果,这是第一个项目。
我认为这是被调用的代码:
ViewOrders.this.orderArrayAdapter.getFilter().filter(s);
除此之外还有其他选项来获取搜索功能吗?
这是我的代码:
Class A
private OrdersList orderArrayAdapter;
private void setupAdapterOrdersList() {
orderArrayAdapter = new OrdersList(getApplicationContext(), R.layout.row_item_view_orders, ordersArray);
if (orderListView != null) {
orderListView.setAdapter(orderArrayAdapter);
}
}
private void searchFromListView() {
etSearch = findViewById(R.id.search_order);
/**
* Enabling Search Filter
* */
etSearch.addTextChangedListener(new TextWatcher() {
@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
// When user changed the Text
ViewOrders.this.orderArrayAdapter.getFilter().filter(s);
}
@Override
public void afterTextChanged(Editable s) {
}
});
}
Class B
package com.example.android.ontrack.adapters;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.TextView;
import com.example.android.ontrack.R;
import com.example.android.ontrack.models.Order;
public class OrdersList extends ArrayAdapter<Order> {
Context mContext;
int mLayoutResourceId;
Order mData[] = null;
public OrdersList(Context context, int resource, Order[] data) {
super(context, resource, data);
this.mContext = context;
this.mLayoutResourceId = resource;
this.mData = data;
}
@Override
public Order getItem(int position) {
return super.getItem(position);
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View row;
LayoutInflater inflater = LayoutInflater.from(mContext);
row = inflater.inflate(mLayoutResourceId, parent, false);
TextView nameOfSchool = row.findViewById(R.id.school_name_orders);
TextView nameOfAgent = row.findViewById(R.id.agent_name);
TextView orderId = row.findViewById(R.id.order_id);
TextView netRevenue = row.findViewById(R.id.net_revenue);
TextView orderQuantity = row.findViewById(R.id.total_quantity);
TextView date = row.findViewById(R.id.date);
Order orders = mData[position];
nameOfSchool.setText(orders.nameOfSchool);
nameOfAgent.setText(String.valueOf(orders.nameOfAgent));
orderId.setText(String.valueOf(orders.orderId));
netRevenue.setText(String.valueOf(orders.netRevenue));
orderQuantity.setText(String.valueOf(orders.totalQuantity));
date.setText(String.valueOf(orders.date));
return row;
}
}
