我正在拆分图像并放置在网格视图中。在网格视图中单击两个图像时,我想交换它们的位置。我可以改变他们的位置,但形象没有改变。我使用位图数组来分割图像并将它们放置在网格视图中。那么如何通过单击两个图像来更改网格视图中的图像?我应该如何进行图像交换?谁能帮助我?
public class Imagepieces extends Activity {
ArrayList<Bitmap> breakedimages,duplicate;
GridView g;
int i=0,temp,temp2,rpos;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_image);
breakedimages = getIntent().getParcelableArrayListExtra("breaked image");
duplicate = new ArrayList<Bitmap>(breakedimages);
Collections.shuffle(duplicate);
g = (GridView) findViewById(R.id.gridView1);
g.setAdapter(new CutAdapter(this, breakedimages));
g.setNumColumns((int) Math.sqrt(breakedimages.size()));
g.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
// TODO Auto-generated method stub
//=================================================
{
}
});
}
class CutAdapter extends BaseAdapter {
int iwidth, iheight;
Context context;
public CutAdapter(Imagepieces ipieces, ArrayList<Bitmap> breakedimages) {
// TODO Auto-generated constructor stub
iwidth = breakedimages.get(0).getWidth();
iheight = breakedimages.get(0).getHeight();
context = ipieces;
}
@Override
public int getCount() {
// TODO Auto-generated method stub
return duplicate.size();
}
@Override
public Object getItem(int arg0) {
// TODO Auto-generated method stub
return duplicate.get(arg0);
}
@Override
public long getItemId(int arg0) {
// TODO Auto-generated method stub
return arg0;
}
@Override
public View getView(int arg0, View arg1, ViewGroup arg2) {
// TODO Auto-generated method stub
ImageView i=new ImageView(context);
i.setLayoutParams(new GridView.LayoutParams(iwidth +5,iheight +5));
i.setPadding(0, 0, 0, 0);
i.setImageBitmap(duplicate.get(arg0));
return i;
}
}
}
如何在网格视图中交换图像?当我在第一次单击时单击网格视图时,我必须获得位置,然后单击第二个位置。然后我在这两个位置的图像,并在更改所有图像之后,如果两者相等,我想与已分割的图像进行比较。然后我想在游戏结束时显示祝酒词。谁能帮我
