Recyclerview item height changing when I do scroll up and down continuously

In one of my applications I am trying to use recyclerview to display content. My content would be like chat history(it may be a single line text or multiple lines text).To implement this I have used recyclerview with Textview height as wrap_content to adjust the height based on the content. For the first time it is loading fine. But when I do scroll up and down I am getting some extra white space for some of the items. (I strongly suspect this extra space is for earlier item height).
Ex: I have a recyclerview list having 1,2,3,4,5.. lines text in each row. When I do scroll up down continuously I am getting row/item height is changing like 1 line text item got 5 lines text space and 5 lines text item got 1 line text.
Please find my adapter code below.

Thanks in Advance.

For sorting you need to Collection.sort method of Java and also you need to implement comparable interface for define your comparison.
CartItemoriginal implements Comparable {
public int compareTo(Object obj) { } }
Updated
public class CartItemoriginal implements Comparable<CartItemoriginal > {
private Float val;
private String id;
public CartItemoriginal (Float val, String id){
this.val = val;
this.id = id;
}
#Override
public int compareTo(ToSort f) {
if (val.floatValue() > f.val.floatValue()) {
return 1;
}
else if (val.floatValue() < f.val.floatValue()) {
return -1;
}
else {
return 0;
}
}
#Override
public String toString(){
return this.id;
}
}
and use
Collections.sort(sortList);

howt to solve the getview's position is cofusition in the baseadapter in android

#Override

Above is the code of getview, I was in the use of staggeredgridview Etsy ，when I scroll the screen,this problem is occurs, a time when the position is out of confusion, as if the location of the position did not be remembered.
The following is a screenshot of position getview：

This issue comes only if you are not controlling getCount() and getItem() methods. Make sure that you are returning your list size as in getCount() like this :
#Override
public int getCount() {
return list.size();
}
and getItem() as :
#Override
public SetterGetterClassName getItem(int position) {
return list.get(position);
}

This is my complete code :

Can't get same value when implementing reset button with spinner and edit text

I have 10 spinner and 10 edit text (user are able to let several spinner and edit text blank), and I also have 2 button to sum value from the selected spinner object and edit text. It's successful to sum the value, but when I use my reset button to get back to the initial state when the app is first launched, I got the problem. The result is wrong, I got the value from the first operation even though I have set it back to the default. This is my code for the reset button
hapus.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v)
{
qty1.setText(null);
qty2.setText(null);
qty3.setText(null);
qty4.setText(null);
qty5.setText(null);
qty6.setText(null);
qty7.setText(null);
qty8.setText(null);
qty9.setText(null);
qty10.setText(null);
spin1.setSelection(0);
spin2.setSelection(0);
spin3.setSelection(0);
spin4.setSelection(0);
spin5.setSelection(0);
spin6.setSelection(0);
spin7.setSelection(0);
spin8.setSelection(0);
spin9.setSelection(0);
spin10.setSelection(0);
sum.setText(null);
hasil = 0;
}
});
And this is a part of my code for the spinner and sum operation
spin8.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener()
{
#Override
public void onItemSelected(AdapterView<?> parent, View selectedItem, int pos, long id)
{
Object item = parent.getItemAtPosition(pos);
value8 = item.toString();
if (item.equals("null"))
{
hrg8 = 0;
}
else if (item.equals("Soto Istimewa"))
{
hrg8 = 24000;
}
else if (item.equals("Soto Biasa"))
{
hrg8 = 17000;
}
else if (item.equals("Nasi Putih"))
{
hrg8 = 4000;
}
else if (item.equals("Emping"))
{
hrg8 = 2000;
}
else if (item.equals("Kerupuk"))
{
hrg8 = 1000;
}
else if (item.equals("Es Teh"))
{
hrg8 = 2000;
}
else if (item.equals("Es Teh Manis"))
{
hrg8 = 3000;
}
else if (item.equals("Es Teh Botol"))

hrg8 = 5000;

Any help will be appreciate, thanks

You are trying to use null as a String:
if (item.equals("null"))
It should be:
if (item == null)
Also the default value of an Spinner or EditText is an empty String (i.e. "") not null. I believe you should use .setText(""); when you reset the values, so really that first if statement should be:
if (item.isEmpty()) // or item.equals("")
Lastly do you have 10 OnItemSelectedListeners that contains 80-90% of the same code? If so your should write one generic listener and use parent.getId() to determine which value to set.
