私はアンドロイドのリストビューと編集テキストの専門家ではありません。しかし、私はこの問題に関していくつかの面倒な問題に悩まされています。 リストビューで値を取得していますが、Edittextに何かを入力し、の値をスクロールしてEditTextの位置を変更します。ここに私のコードです。 //製品クラススクロール中にedittextの値がリストビューに表示されない
public class products {
public String prod_sl;
public String prod_code;
public String product_name;
public String product_desc;
public String prod_qnty;
public String prod_uom;
public String prod_price;
boolean ShowName;
public products(String psl, String pcode,String Name, String Desc, String UOM) {
this.prod_sl = psl;
prod_code = pcode;
prod_qnty="";
prod_price ="";
product_name=Name;
product_desc=Desc;
prod_uom =UOM;
}
/* public boolean isShowName() {
return ShowName;
}
public void setShowName(boolean showName) {
ShowName = showName;
}*/
//sl
public String getSl() { return prod_sl; }
public void setSl(String psl) { this.prod_sl = psl; }
//product code
public String getCode() { return prod_code; }
public void setCode(String pcode) { this.prod_code = pcode; }
//product Name
public String getName() { return product_name; }
public void setName(String product_name) { this.product_name = product_name; }
//product desc
public String getDesc() { return product_desc; }
public void setDesc(String product_desc) { this.product_desc = product_desc; }
//product UOM
public String getUom() { return prod_uom; }
public void setUom(String prod_uom) { this.prod_uom = prod_uom; }
// product quantity
public String getQnty() {
return prod_qnty; }
public void setQnty(String prod_qnty) {
this.prod_qnty = prod_qnty; }
//product price
public String getPrice() {
return prod_price; }
public void setPrice(String prod_price) {
this.prod_price = prod_price; }
}
そしてここアダプタクラス
