How to change background color of first item or any other item of a listview after setAdapter is used? Basically, I want to change inside onCreate and outside of setOnItemClickListener.
Setting List Array Adapter Code:
ArrayAdapter arrayAdapter = new ArrayAdapter(SecondActivity.this,android.R.layout.simple_list_item_1,strings);
listView.setAdapter(arrayAdapter);
Try this
you can do that in getView method at your adapter and if you use ArrayAdapter
you can also override getView
method as following :
ArrayAdapter arrayAdapter = new ArrayAdapter(MainActivity.this,android.R.layout.simple_list_item_1,strings){
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View view;
if(convertView==null) {
LayoutInflater Inflater = (LayoutInflater) MainActivity.this.getSystemService(MainActivity.this.LAYOUT_INFLATER_SERVICE);
view = Inflater.inflate(android.R.layout.simple_list_item_1, null);
}
else
{
view=convertView;
}
if(position==YOUR_TARGET_POSITION_TO_CHANGE_ITS_BACKGROUND)
{
view.setBackgroundColor(0x2196f3);
}
//Update Of textView
TextView txt1=(TextView)view.findViewById(android.R.id.text1);
text1.setText(strings[position]);
//Rest of your code
return view;
}
};
listView.setAdapter(arrayAdapter);
