Set Listview Row Height In Code

I have an Activity containing a ListView based on SimpleCursorAdapter and a button. When I click the button, I want the row height to get bigger. I decided to use TextView height f

Solution 1:

I think you must chage getView() method of your SimpleCursorAdapter, like this:

finalSimpleCursorAdapteradapter=newSimpleCursorAdapter (context, cursor) {
    @Overridepublic View getView(int position, View convertView, ViewGroup parent) {
        finalViewview=super.getView(position, convertView, parent);
        finalTextViewtext= (TextView) view.findViewById(R.id.tvRow);
        finalLayoutParamsparams= text.getLayoutParams();

        if (params != null) {
                params.height = mRowHeight;
        }

        return view;
    }
}

When you click on your button, you must change mRowHeight and notify ListView about changes like adapter.notifyDataSetChanged(). For the first value of mRowHeight you can set this:

mRowHeight = LayoutParams.WRAP_CONTENT

UPD:

If method hasStableIds() of your BaseAdapter return false (it return false as default) you must apply little changes in your getView() (you must set LayoutParams to your View manually):

LayoutParams params = view.getLayoutParams();
if (params == null) { 
    params = new LayoutParams(LayoutParams.MATCH_PARENT, mRowHeight); 
} else {
    params.height = mRowHeight;
}

view.setLayoutParams(params);

Solution 2:

I did something like that :

@OverridepublicViewgetView(int position, View convertView,ViewGroup parent) {
        View view = super.getView(position, convertView, parent);

        TextView textView=(TextView) view.findViewById(android.R.id.text1);
        textView.setHeight(30);
        textView.setMinimumHeight(30);



        / * Couleur de votre choix * / 
        textView . SetTextColor ( Couleur . BLACK );



        retourner voir ; 
    }

You must put both fields textView.setHeight (30); textView.setMinimumHeight (30); or it won't work. For me it worked, & i had the same problem.
