ImageAdapterを設定するための質問がありGridViewます。以下は私のコードですActivity：
public class RestListActivity extends Activity {
//ImageButton [] buttons;
RelativeLayout rl;
int restCount = 0;
//Resources a;
int resIndex = 0;
boolean resFound = false;
int last;
int resCount = 0;
TextView tv;
ViewFlipper vf;
private static final int SWIPE_MIN_DISTANCE = 120;
private static final int SWIPE_MAX_OFF_PATH = 250;
private static final int SWIPE_THRESHOLD_VELOCITY = 200;
private GestureDetector gestureDetector;
View.OnTouchListener gestureListener;
Vector<Bitmap> iconBmp;
Vector<GridView> gvs;
Vector<ImageAdapter> ias;
// TODO Auto-generated constructor stub
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.restlist);
rl = (RelativeLayout) findViewById(R.id.layoutRestPage);
//a=this.getResources();
boolean done = true;
tv = (TextView) findViewById(R.id.textView1);
tv.setText("Sistemi kullandığınız için teşekkür ederiz!");
Button nb = (Button) findViewById(R.id.nextButton);
nb.setOnClickListener(new OnClickListener() {
public void onClick(View view) {
vf.setInAnimation(RestListActivity.this, R.anim.view_right_transition_in);
vf.setOutAnimation(RestListActivity.this, R.anim.view_right_transition_out);
vf.showNext();
}
});
Button pb = (Button) findViewById(R.id.prevButton);
pb.setOnClickListener(new OnClickListener() {
public void onClick(View view) {
vf.setInAnimation(RestListActivity.this, R.anim.view_left_transition_in);
vf.setOutAnimation(RestListActivity.this, R.anim.view_left_transition_out);
vf.showPrevious();
}
});
Button backButton = (Button) findViewById(R.id.restButton);
backButton.setOnClickListener(new OnClickListener() {
public void onClick(View view) {
Log.i("ACTION", "AD BUTTON CLICKED");
try {
Intent i = new Intent(RestListActivity.this, AVMOrderSystemMain.class);
startActivity(i);
} catch (Exception e) {
Log.i("cort", e.toString());
}
}
});
Button hb = (Button) findViewById(R.id.helpButton);
hb.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
Toast.makeText(RestListActivity.this,
"\tSiparis vermek için bir restoran reklamına tıklayarak\n" +
"ilgili restoranın sayfasına gidebilir, ya da restoranlar\n" +
"listesinden bir restoran seçerek, yine ilgili restoranın\n" +
"sayfasına gidebilirsiniz.\n" +
"\tBu sayfadan menü tercihinizi yaparak detayları belirledikten\n" +
"sonra siparişinizi onaylayarak ödemeniz gereken tutarı\n" +
"öğrenebilirsiniz\n", Toast.LENGTH_LONG).show();
}
});
gestureDetector = new GestureDetector(new MyGestureDetector());
gestureListener = new View.OnTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
if (gestureDetector.onTouchEvent(event)) {
return true;
}
return false;
}
};

}
ImageAdapter ia = new ImageAdapter(this);
ia.setBitmaps(bmpSubSet);
ias.add(ia);
GridView gv = new GridView(this);
gv.setId(y);

そして、以下はImageAdapter：
public class ImageAdapter extends BaseAdapter {
private Context mContext;
private ArrayList <Integer> restLogoIDs=new ArrayList<Integer>();
private Resources res;
Vector <Bitmap> restLogos=new Vector<Bitmap>();
public ImageAdapter(Context c) {
mContext = c;
}
public void setResources(Resources r)
{
res=r;
}
public void setImageIDs(ArrayList <Integer> restLogoIDs)
{
this.restLogoIDs=restLogoIDs;
}
////////////////////////////////////////////////////////
public void setBitmaps(Vector <Bitmap> restLogos)
{
this.restLogos=restLogos;
System.out.println("$$$$$$$$$$$$$$$$$$$$"+restLogos.size());
}
////////////////////////////////////////////////////////
public int getCount() {
return restLogoIDs.size();
}
public Object getItem(int position) {
return null;
}
public long getItemId(int position) {
return 0;
}
// create a new ImageView for each item referenced by the Adapter
public View getView(int position, View convertView, ViewGroup parent) {
System.out.println("=============xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx---"+position);
ImageView imageView;
if (convertView == null) { // if it's not recycled, initialize some attributes
imageView = new ImageView(mContext);
imageView.setLayoutParams(new GridView.LayoutParams(180, 180));
imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
//imageView.setPadding(8, 8, 8, 8);
} else {
imageView = (ImageView) convertView;
}
//BURASI DEĞİŞECEK!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
//imageView.setImageResource(restLogoIDs.get(position));
imageView.setImageBitmap(restLogos.get(position));
return imageView;
}
// references to our images
}
Bitmapsメインにセットした後、アダプターに数とサイズを印刷すると、数が正しいActivityことがわかります。Bitmaps何らかの理由でgetView()、アダプタから呼び出されていません。見えますGridViewが空です。これについて助けてもらえますか？
