First, inherit SimpleAdapter
Second, use an overloaded Adapter for the effect
In fact, it is mainly needed to overload SimpleAdapter, I quote the network point of view to write
package meetweb.net.util;
import java.util.List;
import java.util.Map;
import android.content.Context;
import android.graphics.Color;
import android.view.View;
import android.view.ViewGroup;
import android.widget.SimpleAdapter;
public class SpecialAdapter extends SimpleAdapter {
private int[] colors=new int[]{0x30FF0000,0x300000FF};// There is no reference to use here , It simply refers to an array operation
public SpecialAdapter(Context context, List<? extends Map<String, ?>> data,
int resource, String[] from, int[] to) {
super(context, data, resource, from, to);
}
@Override
public View getView(int position ,View convertView,ViewGroup parent){
View view=super.getView(position, convertView, parent);
int colorPos=position%colors.length;
if(colorPos==1)
view.setBackgroundColor(Color.argb(250, 255, 255, 255)); // Color Settings
else
view.setBackgroundColor(Color.argb(255, 224, 243, 250));// Color Settings
return view; } }
Second, use an overloaded Adapter for the effect
import meetweb.net.util.SpecialAdapter;
.
private SpecialAdapter simpleAdapter = null;
public void ShowData(){
RateList = rateService.findAll();
System.out.println(RateList);
LVrate=(ListView) this.findViewById(R.id.lvrate);
simpleAdapter = new SpecialAdapter(this, RateList, R.layout.accuratelistitem, new String[]{"yearlimit","year1","year2"},
new int[]{R.id.tv_yearlimit,R.id.tv_year1,R.id.tv_year2});
LVrate.setAdapter(simpleAdapter);
//listView.setOnItemClickListener(listener);
}
