Use getView() without Layout Inflater

Question

I want to populate items without using a xml layout instead I want to create view at the runtime.This is my getView() method.

 public View getView(final int position, View convertView, ViewGroup parent) {

    EditText v ;    

    if(convertView ==null)
    {
        v = new EditText(mContext);
        convertView = v;
        convertView.setTag(R.string.edittext_child, v);

    }
    else
    {
        v = (EditText)convertView.getTag(R.string.edittext_child);
    }
    v.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, 80));
    v.setBackgroundDrawable(mContext.getResources().getDrawable(R.drawable.custom_edit));
    v.setEms(12);
    v.setInputType(InputType.TYPE_TEXT_FLAG_NO_SUGGESTIONS);
    v.setPadding(10, 0, 5, 0);
    v.setHint(Ids[position]);
    return convertView;
}

I am getting this error while returning my view.

java.lang.ClassCastException: android.view.ViewGroup$LayoutParams cannot be cast to android.widget.AbsListView$LayoutParams

You can treat an `EditText` as a `View` but not the other way around. — Karthik Balakrishnan, Jun 18 '13 at 10:32
I think you need to use LinearLayout.LayoutParams instead of ViewGroup.LayoutParams Remove import line for LayoutParams and import LinearLayout.LayoutParams. It should work. — Hardik Joshi, Jun 18 '13 at 10:33

Right now propably you've imported the LinearLayout Layout Params which is a wrong import. Thats why you're getting

java.lang.ClassCastException: android.view.ViewGroup$LayoutParams cannot be cast to android.widget.AbsListView$LayoutParams

Because you're trying to add Linear Layout params to AbsList Layout which should be filled with AbdList Params

This line is wrong:

v.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, 80));

Change LayoutParams to :

AbsListView.LayoutParams

or change your import:

import android.widget.AbsListView;

Use AbsListView.LayoutParams

 v.setLayoutParams(new AbsListView.LayoutParams(LayoutParams.MATCH_PARENT, 80));
