没有项目的点击监听器正从gridview的所有图像 [英] not getting all images from gridview on item click listener
本文介绍了没有项目的点击监听器正从gridview的所有图像的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
I M在开发从Inter网的GridView显示图片...现在我想通过对GridView的单击事件的所有图像库的应用程序。
我想，我的画廊不应该下载所有图像时，画廊活动called..so，我想从网格视图所有的图像传递到画廊的活动...
有没有什么解决办法传递o下一个活动的GridView的所有图像，。？
我的GridView的图像来自互联网和我不是存储所有图像局部...只是在网格视图中显示。
这是我的code ..

解决方案
，当你在GridView中点击一个图像上可以将该图像存储在一个位图。编写以下code在你的注释部分。
ImageView的IM =（ImageView的）视图。
可绘制D = im.getDrawable（）;
位图位图=（（BitmapDrawable）D）.getBitmap（）;
同样，你也可以将所有的位图作为当图像clicked.Hope这一点，你所寻找的。什么
i m developing an application in which gridview display images from inter net...now i want to pass all image to gallery on gridview's click event..
I want that my gallery should not download all images when gallery activity is called..so,i want to pass all image from grid view to gallery activity...
is there any solution to pass all images of gridview o next activity,.?
My gridview's images are come from internet and i m not storing all images locally...just displaying in grid view.
here is my code..
mainfile.java
public class PhotoList extends Activity
{
Bundle bundle;
String key;
int totalPhoto;
ImageView imageArray[];
HashMap<String,ArrayList<ChildPhotos>> childPhotosWithId;
ArrayList<ChildPhotos> childPhotoList;
String allURL[];
String title,discription;
TextView PhotosTitle,PhotosDiscription;
public static Bitmap[] downloadedChildPhotos;
public static int downloadedChildPhotosIndex=0;
ImageView img[];
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.photo_list);
GridView gridview = (GridView) findViewById(R.id.gridview);
bundle=getIntent().getExtras();
key=bundle.getString("key");
totalPhoto=Integer.parseInt(key);
img=new ImageView[totalPhoto];
title=bundle.getString("title");
discription=bundle.getString("discription");
childPhotosWithId=PhotosXMLHanler.getChildPhotoWithId();
childPhotoList=childPhotosWithId.get(key);
ChildPhotos c[]=new ChildPhotos[childPhotoList.size()];
allURL=new String[childPhotoList.size()];
downloadedChildPhotos=new Bitmap[childPhotoList.size()];
PhotosTitle=(TextView)findViewById(R.id.photosTitleInGridView);
PhotosDiscription=(TextView)findViewById(R.id.photoDiscriptionInGridView);
PhotosTitle.setText(title);
PhotosDiscription.setText(discription);
for(int i=0;i<childPhotoList.size();i++)
{
c[i]=new ChildPhotos();
c[i]=childPhotoList.get(i);
String url=c[i].getChildPhoto();
allURL[i]=url;
System.out.println("url "+(i+1)+c[i].getChildPhoto());
}
gridview.setAdapter(new ImageAdapter(this,allURL));
gridview.setOnItemClickListener(new OnItemClickListener()
{
public void onItemClick(AdapterView<?> parent, View v, int position, long id)
{
Toast.makeText(PhotoList.this, "" +id, Toast.LENGTH_SHORT).show();
GridView g=(GridView)v.findViewById(R.id.gridview);
for(int i=0;i<totalPhoto;i++)
{
img[i]=new ImageView(PhotoList.this);
System.out.println("image ==>"+img[i].getId());
}
/*
here i want to fetch all images from grid view...
*/
// Intent intent=new Intent(PhotoList.this,GalleryView.class);
//
// startActivityForResult(intent, 0);
}
});
}
class ImageAdapter extends BaseAdapter
{
private Context mContext;
String[] allURL;
ImageLoader imageLoader;
public ImageAdapter(Context c,String[] allURL)
{
mContext = c;
this.allURL=allURL;
imageLoader = new ImageLoader(mContext);
}
public int getCount()
{
return allURL.length;
}
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) {
ImageView imageView;
if (convertView == null)
{
// if it's not recycled, initialize some attributes
imageView = new ImageView(mContext);
imageView.setLayoutParams(new GridView.LayoutParams(85, 85));
imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
imageView.setPadding(8, 8, 8, 8);
}
else
{
imageView = (ImageView) convertView;
}
imageView.setTag(allURL[position]);
imageLoader.DisplayImage(allURL[position],PhotoList.this,imageView);
///here i use thread which set image in backgrund...as images come from internet..
return imageView;
}
}
}
解决方案
As and when you click on one image in gridview you can store that image in a bitmap. Write the following code in your commented portion.
ImageView im=(ImageView) view;
Drawable d = im.getDrawable();
Bitmap bitmap = ((BitmapDrawable)d).getBitmap();
Likewise you can store all the bitmap as when the image is clicked.Hope this what you are looking for.
