我找到了另一个有同样问题的帖子，但那个答案对我不起作用，所以我希望有人能帮我解决这个问题。
我有多个表格，每个表格都有一个EditText和一个按钮。Button用于将 的值存储在EditText变量中。
这是我的桌面适配器。
package com.example.vanhulzenapp;
import java.util.List;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.EditText;
import android.widget.ImageButton;
import android.widget.TextView;
public class ProductListAdapter extends BaseAdapter {
private final List<TableRow> rows;
/**
* Adapter for TableRow-objects
*/
public ProductListAdapter(final Context context, final int itemResId, final List<TableRow> items){
this.rows = items;
}
public int getCount(){
return this.rows.size();
}
public Object getItem(int position){
return this.rows.get(position);
}
public long getItemId(int position){
return position;
}
/**
* Set the content for a row here
*/
public View getView(int position, View convertView, ViewGroup parent){
final TableRow row = this.rows.get(position);
View itemView = null;
if (convertView == null){
LayoutInflater inflater = (LayoutInflater) parent.getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
itemView = inflater.inflate(R.layout.list_item,null);
} else {
itemView = convertView;
}
// Set the text of the row
TextView productname = (TextView) itemView.findViewById(R.id.productName);
productname.setText(row.getName());
TextView productprice = (TextView) itemView.findViewById(R.id.productPrice);
productprice.setText(row.getPrice());
/*EditText productvalue = (EditText) itemView.findViewById(R.id.editValue);
productvalue.setText(Integer.toString(row.getValue()));*/
// Remember the row for each button so that we can refer to
// it when the button is clicked
ImageButton addItemButton = (ImageButton) itemView.findViewById(R.id.addItemButton);
addItemButton.setTag(row);
return itemView;
}
}
这是TableRow课
package com.example.vanhulzenapp;
public class TableRow{
private String name;
private String price;
private int value;
public TableRow(String name, String price){
this.name = name;
this.price = price;
}
public void setName(String name){
this.name = name;;
}
public String getName(){
return name;
}
public void setValue(int value){
this.value = value;
}
public int getValue(){
return value;
}
public void setPrice(String price){
this.price = price;
}
public String getPrice(){
return price;
}
}
以及单击事件发生的主类。按钮通过使用知道它在哪一行，gettag()
但我无法EditText知道它在哪一行。
