Hello i try to use my own adapter on Gridview.
My problem is that the position in getView is not increasing.
This is my code:
public class WorkourLogBuilder {
String[] values = new String[11];
Context mContext;
Map<Integer, String[]> valuesArray;
int rowsCount = 0;
int mode;
int adappterRowsCount = 0;
static final int AEROBIC = 1;
static final int ANAEROBIC = 0;
public WorkourLogBuilder(Context context, int modeChoosed)
{
mContext = context;
mode = modeChoosed;
valuesArray = new HashMap<Integer, String[]>();
}
public void commintRow()
{
valuesArray.put(rowsCount, values);
rowsCount++;
Log.i("rowsCount", rowsCount+"");
values = new String[11];
}
public void setWorkoutWeight(String value)
{
values[0] = value;
}
public void setSets(String value)
{
values[1] = value;
}
public void setReps(String value)
{
values[2] = value;
}
public void setWorkTime(String value)
{
values[3] = value;
}
public void setWDayTime(String value)
{
values[4] = value;
}
public void setDistance(String value)

values[5] = value;
}
public void setSpeed(String value)
{
values[6] = value;
}
public void setRestTime(String value)
{
values[7] = value;
}
public void setCaloires(String value)
{
values[8] = value;
}
public void setHeartBeat(String value)
{
values[9] = value;
}
public void setComment(String value)
{

grid.setAdapter(new ImageAdapter());
return v;
}
public class ImageAdapter extends BaseAdapter {

When i look at the logcat i that the position log is always 0.
Why position is not increasing?
You are not returning from getItem() correctly:
public Object getItem(int position) {
return position;
}
It should be:
public Object getItem(int position) {
return valuesArray.get(position);
}
you have wrong in getItem()
public Object getItem(int position) {
return valuesArray.get(position);
}
it should return an Object not an the position, so basically it is always returning 0

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.

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 :

I am trying to build a demo chatting App.I want to show the messages with section headers as Dates like "Today","Yesterday","May 21 2015" etc.I have managed to achieve this but since the new View method gets called whenever I scroll the list.The headers and messages get mixed up.
For simplicity, I have kept the header in the layouts itself and changing its visibility(gone and visible) if the date changes.
Can you help me out with this? Let me know if anyone needs any more info to be posted in the question.

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()

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.
