I want that 200 pictures are in every row of a ListView. So the ListView have 200 rows. But now i dont know where i can put my code that the pictures are in every row....
Heres my adapter:
public class CustomAdapter extends BaseAdapter implements View.OnClickListener {
/*********** Declare Used Variables *********/
private Activity activity;
private ArrayList data;
private static LayoutInflater inflater=null;
public Resources res;
ListModel tempValues=null;
int i=0;
/************* CustomAdapter Constructor *****************/
public CustomAdapter(Activity a, ArrayList d,Resources resLocal) {
/********** Take passed values **********/
activity = a;
data=d;
res = resLocal;
/*********** Layout inflator to call external xml layout () ***********/
inflater = ( LayoutInflater )activity.
getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
/******** What is the size of Passed Arraylist Size ************/
public int getCount() {
if(data.size()<=0)
return 1;
return data.size();
}
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
/********* Create a holder Class to contain inflated xml file elements *********/
public static class ViewHolder{
public TextView text;
public TextView text1;
public TextView textWide;
public ImageView image;
}
/****** Depends upon data size called for each row , Create each ListView row *****/
public View getView(int position, View convertView, ViewGroup parent) {
View vi = convertView;
ViewHolder holder;
if(convertView==null){
/****** Inflate tabitem.xml file for each row ( Defined below ) *******/
vi = inflater.inflate(R.layout.tabitem, null);
/****** View Holder Object to contain tabitem.xml file elements ******/
holder = new ViewHolder();
holder.text = (TextView) vi.findViewById(R.id.text);
holder.text1=(TextView)vi.findViewById(R.id.text1);
holder.image=(ImageView)vi.findViewById(R.id.image);
/************ Set holder with LayoutInflater ************/
vi.setTag( holder );
}
else
holder=(ViewHolder)vi.getTag();
if(data.size()<=0)
{
holder.text.setText("No Data");
}
else
{
/***** Get each Model object from Arraylist ********/
tempValues=null;
tempValues = ( ListModel ) data.get(position);
/************ Set Model values in Holder elements ***********/
holder.text.setText(tempValues.getCompanyName());
holder.text1.setText( tempValues.getUrl() );
holder.image.setImageResource(
res.getIdentifier(
"com.androidexample.customlistview:drawable/"+tempValues.getImage(),null,null));
/******** Set Item Click Listner for LayoutInflater for each row *******/
vi.setOnClickListener(new OnItemClickListener( position ));
}
return vi;
}
@Override
public void onClick(View v) {
Log.v("CustomAdapter", "=====Row button clicked=====");
}
/********* Called when Item click in ListView ************/
private class OnItemClickListener implements View.OnClickListener{
private int mPosition;
OnItemClickListener(int position){
mPosition = position;
}
@Override
public void onClick(View arg0) {
CustomListView sct = (CustomListView)activity;
/**** Call onItemClick Method inside CustomListViewAndroidExample Class ( See Below )****/
sct.onItemClick(mPosition);
}
}
And here is my own code to get the pictures from the internet:
public static Bitmap getBitmapFromURL(String src) {
try {URL url = new URL(src);
return BitmapFactory.decodeStream(url.openConnection().getInputStream());
}
catch(Exception e){
e.printStackTrace();
}
return null;
}
public String getPictureName (int i){
String in = ""+i+"";
if(in.length() == 1){
return "000"+in;
}
else if(in.length() == 2){
return "00"+in;
}
else if(in.length() == 3){
return "0"+in;
}
else{
return in;
}
}
for(int i = 1; i <= 200; i++){
final int ii = i;
final ImageView imageView = new ImageView(CustomListView.this);
RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT,RelativeLayout.LayoutParams.WRAP_CONTENT);
//linearLayout.addView(imageView,lp);
Thread thread = new Thread(){
@Override
public void run(){
final Bitmap bm = getBitmapFromURL("http://myURL.de/picture_"+getPictureName(ii)+".jpg");
runOnUiThread(new Runnable() {
@Override
public void run() {
if(bm !=null){
imageView.setImageBitmap(bm);
}
else {
//linearLayout.removeView(imageView);
}
}
});
}
};thread.start ();
}
