Android - Unexpected Behavior of Keypad - EditText in ListView

Question

I am stuck with problem since last two days i.e. i have created ListView with Custom View with Variant SubLayout like:

Problems:

• When i click on EditText of Qty, its displaying Soft Input Keyboard with Numeric Keypad and immediately focus lost from
  edittext with change of alphabetic keypad. (First ScreenShot Below)

• on Second time focus of EditText its works fine and taking numeric values but while scrolling its change keypad from numeric to alphabetic. (Second ScreenShot Below)

Actually i can understand problem is what that It is changing on showing/hiding keyboard and because of that view is updating every time so what can i do for keep focusing on EditText or prevent to Refresh Views on Show/Hide Keyboard.

My Adapter Code is:

class MyGridViewAdapter extends BaseAdapter {

    private ArrayList<ProductItems> productItemList;
    private LayoutInflater inflater = null;

    ViewHolder holder;

    double productQtyValue;
    double productRateValue;
    double productDiscountValue;
    double productOfferDiscValue;
    double productDiscountedRateValue;

    double amount;

    public MyGridViewAdapter(ArrayList<ProductItems> productItemsList) {
        // TODO Auto-generated constructor stub
        this.productItemList = productItemsList;
        inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    }

    @Override
    public int getCount() {
        // TODO Auto-generated method stub
        return productItemList.size();
    }

    @Override
    public Object getItem(int position) {
        // TODO Auto-generated method stub
        return productItemList.get(position);
    }

    @Override
    public long getItemId(int position) {
        // TODO Auto-generated method stub
        return position;
    }

    @Override
    public View getView(final int position, View convertView, ViewGroup parent) {
        // TODO Auto-generated method stub

        if (convertView == null) {

            if(isViewWithCatalog)

SubLayouts of that Product Row is Creating from following files.

list_product_variant_single_row_view.xml

list_product_variant_multiple_row_view.xml

Noticed: View is refreshing and losing focus from edittext when keypad is open. that's why keypad is changing view from numeric to alphabetic. I have changed AndroidManifest.xml with android:windowSoftInputMode="stateAlwaysHidden" and android:configChanges="keyboardHidden|orientation" but not working for me.

Your Help would be appreciated.

have you try to set this two : android:descendantFocusability="afterDescendants" and android:focusable="false" propertiest to ListView ? – Contagious

Not working. I tried. same output. – Peaked

@MuhammadBabar Edited. Check it – Peaked

i mean R.layout.list_product_view_catalog and R.layout.list_product_view. the links you shared are not working – Wheelhouse

Its working perfectly here. can you check it once.? – Peaked

The requested URL /3ic89jxr was not found on this server. – Wheelhouse

Yes i guess so. Please add the files with your question. – Wheelhouse

I don't see any edit text in above posted layouts? – Wheelhouse

I have the same problem! @PratikButani any solution yet? – Spokeswoman

Answer 1

This is due to the listview recycle mechanism. Already the issue is raised in google android groups. It is better to place quantity items at check out or change edittext to drop downs by giving numbers in dropdowns.

EDIT It is working perfectly with this option:

android:windowSoftInputMode="stateAlwaysHidden|adjustPan"

Answer 2

Add this line on your code:

input.setRawInputType(Configuration.KEYBOARD_12KEY);

this will show only the numeric keyboard. check this..
