在按钮上单击自定义BaseAdapter的EditText点击更新数据库 [英] Custom BaseAdapter EditText click and update database in button click
问题描述
我要通过关系到自定义BaseAdapter一个问题。首先我作为定制对话框下方
I am going through a problem that is related to Custom BaseAdapter. First i have custom dialog as below
正如你可以看到为三TextView的,一个EditText上(),一键(红十字会)这里的另一个按钮,当前的能见度假的,那按钮保存按钮。现在,我想那是什么 - 当我的EditText单击保存,然后对应的列表可见的按钮(如果我对第三列表EDITTEXT那么只有第三个列表的保存应该可见单击手段)。而当我的EditText改变一些文字,然后点击保存按钮,然后它会更新数据库的该行。
As you can see there is three TextView , One EditText ( ) , One Button ( red Cross ) here another button which current visibility is false , and that button is Save button. Now what i want is that - When i click on EditText then Save Button of Corresponding List become visible ( means if i click on EditTExt of third List then only third list's Save should visible). And when i change some Text in EditText and click on SAVE button then it will update that row of database.

正如你可以看到,我创建了一个clickHandler方法,将处理上的自定义对话框中的所有点击。现在,我是个要发布我的clickHandler方法,
AS you can see that i created a clickHandler Method which will handle all click on Custom dialog. Now i ma going to post my clickHandler method.
public void clickHandler(View v)
{
if (v.getId() == R.id.orderQty)
{
System.out.println(" edit text click");
ImageView imageView = (ImageView)v;
imageView.setId(R.id.save_on_id);
imageView.setVisibility(ImageView.VISIBLE);
}
}
不过,这不是为我工作。当这部分将超过然后,我会朝着这个移动
But this is not working for me . When this part will be over then i will move towards this
if (v.getId() == R.id.save_on_id){
// update database row
}
这是我的座级
public class OrderViewHolder {
TextView tvTitle;
TextView tvPrice;
ImageButton ivDelete;
TextView tvMultiplication;
ImageView imgv_edt_order;
TextView item_name;
TextView item_cost;
EditText edtxt_qty;
TextView item_total_amount;
public TextView getTvTitle() {
return tvTitle;
}
public void setTvTitle(TextView tvTitle) {
this.tvTitle = tvTitle;
}
public TextView getTvMultiplication() {
return tvMultiplication;
}
public void setTvMultip(TextView tvMultiplication) {
this.tvMultiplication = tvMultiplication;
}
public ImageButton getIvDelete() {
return ivDelete;
}
public void setIvDelete(ImageButton ivDelete) {
this.ivDelete = ivDelete;
}
public ImageView getIvImageView() {
return imgv_edt_order;
}
public void setIvImageView(ImageView imgv_edt_order) {
this.imgv_edt_order = imgv_edt_order;
}
public TextView getTvItemCost() {
return item_cost;
}
public void setTvItemCost(TextView item_cost) {
this.item_cost = item_cost;
}
public EditText getEdtTxtQty() {
return edtxt_qty;
}
public void setEdtTxtQty(EditText edtxt_qty) {
this.edtxt_qty = edtxt_qty;
}
public TextView getTvAmount() {
return item_total_amount;
}
public void setTvAmount(TextView item_total_amount) {
this.item_total_amount = item_total_amount;
}
}
我希望我能来阐述我的问题给大家。虽然我知道,我是有点刺鼻问单线程三问,但实际上我是个从所有这些问题受够了。任何帮助真的是AP preciated。在此先感谢所有
I hope i am able to elaborate my problem to all of you. Although i know that i is little irritating to ask three question in single thread , but really i ma fed-up from all these issue. Any help is really appreciated . Thanks in advance to all
推荐答案
可能这不是一个完美的解决方案,因为你应该考虑使用时重新设计code 的ListView
。 的ListView
回收并重新使用它的查看
S当你滚动它向上和向下。这样一来,你可以观察一样,如果你启用的ImageView
在一行中,的ImageView
其他行会也是可见的。
May be this is not a perfect solution because you should consider redesigning your code when using ListView
. ListView
recycles and reuses it's View
s when you scroll it up and down. As a result, you can observe like if you enable the ImageView
in one row, the ImageView
of other row will be also visible.
public void clickHandler(View view) {
if (view.getId() == R.id.orderQty) {
LinearLayout layout = (LinearLayout) view.getParent().getParent();
ImageView imageView = (ImageView) layout.findViewById(R.id.save_on_id);
imageView.setImageResource(R.drawable.save_on);
imageView.setVisibility(ImageView.VISIBLE);
}
}
