Unable to calculate proper value from each row in ListView

Unable to calculate proper value from each row in ListView - android

// i have two button for increasing and decreasing the quantity, after increasing or decreasing the value i want to calculate price from each row but it is not giving correct value.Also the quantity getting changed while scrolling .Mostly the above said problem occurs whenever the size of listview is more than screen size.

Never update an item view in a list from the event handler (controller).
It looks like you are correctly updating the model (prodetailarray), but in an onClick or any event handler, all you want to do is update the model and then call notifyDataSetChanged(). This will inform your list view that the model has changed, and the list view will regenerate item views based on the new model data.
If that's not sufficient to solve your problem, you'll need to post your entire adapter code so we can identify the problem.

Android data storage and retrieving

I developed an android application in which a users provides 6 pieces of information in 6 separate text boxes (information such as first name, last name, middle name, mobile number email id etc)
When the user presses a Save button, I need to store this information and be able to recall this information when the Recall button is pressed.
What is the next step to accomplish this
My code so far is below:

db = openOrCreateDatabase("MyDBI", MODE_PRIVATE, null);
db.execSQL("CREATE TABLE IF NOT EXISTS TABLE1 ();");
You can create database using this code
db.execSQL("INSERT INTO TABLE1 VALUES('"+fname"');
And values can be inserted to this database using this code.
A tablelayout can be created and the saved details can be displayed in this tablelayout. Give clickable option and clicking all the details can be transferred using intents to the previous activity.

Change two textViews inside a listview

Let's say, I have two textviews, TextView A and B.
when I click on A, I need to change both textviews;
When I click on B, I need it to do something else.
I used the setTag(key,A); and setTag(key,B); The textView A changed correctly but the textView B is null. And when I click on B it works.
Here is my code :
public class CustomeAdapterHowComment extends ArrayAdapter<ItemsHowComment> {
Context context;
ItemsHowComment items;
List<LikersComment> likeItems;
List<ItemsHowComment> Items1;
Bitmap bitmap;
String imageUser = "";
String filePath_Image = "/Pictures/jehad/joj/";
String user_id = "1510";

String response;
public CustomeAdapterHowComment(Context context, int textViewResourceId,
List<ItemsHowComment> objects) {
super(context, textViewResourceId, objects);
// TODO Auto-generated constructor stub
this.context = context;
}

Use
View view = v.getParent();
and then try to initialize views with view in onClick
You can set Tag
h.name.setOnClickListener(listener);
h.name.setTag(h.numoflike); // use setTag only once
h.numoflike.setOnClickListener(listener);
h.numoflike.setTag(h.name); // use setTag only once
Then in on click
public void onClick(View v) {
switch(v.getId())
{
case R.id.CommentName :
TextView tv1 = (Button) v.getTag();
TextView tv2 = (TextView) v;
tv1.setText("clicked");
tv2.setText("clicked");
break;
case R.id.CommentNumOfLike :
//do something
break;
}
}
Or in onClick Initialize yours views
View view = v.getParent();
TextView tv = view.findVIewById(R.id.CommentName);
TextView tv1 = view.findVIewById(R.id.CommentNumOfLike);
tv.setText("clicked");
tv1.setText("clicked");
