How do I make a variable global across a Java file

Question

In lua I could just do global variablename and bam its global is there a simple way to do this in java?

Here is my code, I want the loc variable to be global so the public View getView(int position, View convertView, ViewGroup parent){ can use it:

 class custom_row_adapter extends ArrayAdapter<Integer> { custom_row_adapter(Context context, int picId, String url) { super(context, R.layout.activity_custom_row_adapter, picId); String loc = url; } @Override public View getView(int position, View convertView, ViewGroup parent){ LayoutInflater picInflater = LayoutInflater.from(getContext()); View customView = picInflater.inflate(R.layout.activity_custom_row_adapter, parent, false); String singlePic = getItem(loc + String.valueOf(position) + ".jpg"); **//this is where loc is viewed** ImageView theImage = (ImageView) customView.findViewById(R.id.singleImg); Glide.with(this).load(singlePic).into(theImage); return customView; } 

}

Answer 1

just add it as and field like this

public class example {

private String loc;

class custom_row_adapter extends ArrayAdapter<Integer> {
    custom_row_adapter(Context context, int picId, String url) {
        super(context, R.layout.activity_custom_row_adapter, picId);
        loc = url;
    }
  }
}
