Recyclerview scroll to empty Edit Text


Recyclerview scroll to empty Edit Text

it should still fix some issue I am using Edit text as a view of android Recycler view but, when a user does not enter any value in Edit text then I am not able to show an Error message or auto scroll on that empty Edit text. I am storing some data into the database using recycler view edit text, I searched very much but I didn't found any helping material. I want to submit that recycler view data before validating all fields (Edit text). , Solved.
code :
int counter = 0;
                                    for(int i=0;i<stockData.length;i++) {
                                        for (int j = 0; j < stockData[i].length; j++) {
                                            if((stockData[i][0]==null || stockData[i][0].matches("")) ||
                                                    ((stockData[i][1]==null || stockData[i][1].matches("")) ||
                                                            (stockData[i][4]==null || stockData[i][4].matches("Stock"))))
                                            {
                                                counter++;
                                                //Log.d(Constants.TAG,"sale is empty and index is "+i);
                                                mPromoter_recyclerView.scrollToPosition(i);
                                                break;
                                            }

                                        }
                                        if(counter>0)
                                            break;
                                    }

Is there a way to programmatically scroll a scroll view to a specific edit text?

Is there a way to programmatically scroll a scroll view to a specific edit text?

I wish did fix the issue. I have a very long activity with a scrollview. It is a form with various fields that the user must fill in. I have a checkbox half way down my form, and when the user checks it I want to scroll to a specific part of the view. Is there any way to scroll to an EditText object (or any other view object) programmatically?
code :
private final void focusOnView(){
        your_scrollview.post(new Runnable() {
            @Override
            public void run() {
                your_scrollview.scrollTo(0, your_EditBox.getBottom());
            }
        });
    }

I wish did fix the issue. Both previously pointed out solutions can work. But there might still be a problem if the edittext is at the bottom of the ListView where it would still be covered by the onscreen keyboard. Not sure if a scrollview can be scrolled to a point where there is no more content.
What i've seen is that you might use two contradicting flags in your manifest:
code :
android:windowSoftInputMode="stateHidden|adjustResize|adjustPan" > </activity>

hope this fix your issue RecyclerView sizes itself based on its child views if wrap_content and no explicit minimum height has been set. In your child RecyclerView you have to consider change as follows
code :
<android.support.v7.widget.RecyclerView
    android:id="@+id/product_recycle_list"
    android:orientation="horizontal"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"/>
How to get data from Edit Text in a RecyclerView?

this one helps. You don't need to use so many lists, just create a class that will contain all the data of single item, there is no need for buttons, use just text change listener instead.
sample code
code :
public class RetItem
{
    public String _itemName;
    public String _itemQty;
    public String _itemPcode;
    public String _itemPlant;
}

public class SelectItemAdapter extends RecyclerView.Adapter<SelectItemAdapter.ItemHolder> {

    private List<RetItem> _retData;
     public SelectItemAdapter(Context context, String[] mDataset) {
        layoutInflater = LayoutInflater.from(context);
        _retData = new ArrayList<RetItem>(mDataset.length);
        this.mDataset = mDataset;
    }

      @Override
    public void onBindViewHolder(SelectItemAdapter.ItemHolder holder, final int position) {
        holder.setItemName(itemsName.get(position));
        holder.setItemName.addTextChangedListener(new TextWatcher() {

           public void afterTextChanged(Editable s) {}

           public void beforeTextChanged(CharSequence s, int start,
             int count, int after) {
           }

           public void onTextChanged(CharSequence s, int start, int before, int count) {
             _retData.get(position)._itemName = s.toString();
           }
          });

        holder.setItemQty(itemsQty.get(position));
        holder.setItemQty.addTextChangedListener(new TextWatcher() {

           public void afterTextChanged(Editable s) {}

           public void beforeTextChanged(CharSequence s, int start,
             int count, int after) {
           }

           public void onTextChanged(CharSequence s, int start, int before, int count) {
             _retData.get(position)._itemQty = s.toString();
           }
          });

        holder.setItemPCode(itemsPCode.get(position));
        holder.setItemPCode.addTextChangedListener(new TextWatcher() {

           public void afterTextChanged(Editable s) {}

           public void beforeTextChanged(CharSequence s, int start,
             int count, int after) {
           }

           public void onTextChanged(CharSequence s, int start, int before, int count) {
             _retData.get(position)._itemPcode = s.toString();
           }
          });       
        holder.setItemPlant(itemPlant.get(position));
        holder.setItemPlant.addTextChangedListener(new TextWatcher() {

           public void afterTextChanged(Editable s) {}

           public void beforeTextChanged(CharSequence s, int start,
             int count, int after) {
           }

           public void onTextChanged(CharSequence s, int start, int before, int count) {
             _retData.get(position)._itemPlant = s.toString();
           }
          });
    }

    public List<RetItem> retrieveData()
    {
        return _retData;
    }
}

it should still fix some issue Following is my answer i found from other SO questions and google.It will help when edittext is focused parent scroll is not work.
code :
full_address.setOnTouchListener(new EditText.OnTouchListener() {
                @Override
                public boolean onTouch(View v, MotionEvent event) {
                    int action = event.getAction();
                    switch (action) {
                        case MotionEvent.ACTION_DOWN:
                            // Disallow ScrollView to intercept touch events.
                            v.getParent().requestDisallowInterceptTouchEvent(true);
                            break;

                        case MotionEvent.ACTION_UP:
                            // Allow ScrollView to intercept touch events.
                            v.getParent().requestDisallowInterceptTouchEvent(false);
                            break;
                    }

                    // Handle ListView touch events.
                    v.onTouchEvent(event);
                    return true;
                }
            });
