全部活动课，其中我想全屏显示图像。我有一个显示在GridView它的所有图像。我不是在这所面临的问题，但是当我点击GridView中的形象它为我作我召刚XML文件。我想我做错了的地方在这里呼吁中的id FullImageAcitivity文件。

解决方案

在你的 LatestTab

声明列表作为一个类成员

 列表＆LT;项目＆GT;项目=新的ArrayList＆LT;项目＆GT;（）; 

添加项目到列表中。

  items.add（新项目（一，R.drawable.abstact_one））;items.add（新项目（二，R.drawable.abstract_three））;items.add（新项目（三公，R.drawable.image_two））;items.add（新项目（四，R.drawable.image_four））;items.add（新项目（十二五，R.drawable.image_five））;items.add（新项目（六个一，R.drawable.image_nine））;items.add（新项目（七宗罪，R.drawable.image_ten））; 

您Item类

 公共类项目{字符串名称;INT绘制;公众诠释getDrawable（）{    返回绘制;}公共无效setDrawable（INT绘制）{    this.drawable =绘制;}公共项目（字符串名称，诠释ID）{    this.name =名称;    this.drawable = ID;}公共字符串的getName（）{    返回名称;}公共无效setname可以（字符串名称）{    this.name =名称;}} 

通过列表适配器类的构造函数

  gridView.setAdapter（新ImageAdapter（这一点，项目））; 

在构造

 列表＆LT;项目＆GT;项目;  公共ImageAdapter（上下文的背景下，列表与LT;项目＆GT;项目）{   充气= LayoutInflater.from（上下文）;   this.items =物品; } 

然后getVIew

 项目项=（项目）items.get（I） picture.setImageResource（item.getDrawable（））; 

然后在项目点击监听器

 项项= items.get（位置）;  INT ID = item.getDrawable（）;  意图I =新意图（getApplicationContext（），FullImageActivity.class）;  i.putExtra（idkey，ID）; //通过ID  startActivity（ⅰ）; 

然后在FullImageActivity

  INT ID = getIntent（）getIntExtra（idkey）; //获取ID  imageview.setImageResource（ID）; //设置绘制到ImageView的 

Full Activity Class where the I want to display the Image in full Screen. I have all the images showing it in the gridView. I am not facing problem in that, however when I click on the image of the gridview it shows me the just the xml file which I have called. I guess I am doing wrong somewhere calling the id here in the FullImageAcitivity file.

public class FullImageActivity extends Activity {

Button download, setas;
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.full_image);
    setas = (Button) findViewById(R.id.setas);
    download = (Button)findViewById(R.id.download);
    final Intent i = getIntent();
    final   List<Item> items = new ArrayList<Item>();
    final ImageAdapter imageAdapter = new ImageAdapter(this);       
    ImageView imageView = (ImageView) findViewById(R.id.full_image_view);
    imageView.setImageResource(items.indexOf(i));
    setas.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
             WallpaperManager myWallpaperManager
             = WallpaperManager.getInstance(getApplicationContext());
            try {
                myWallpaperManager.setResource(imageAdapter.items.indexOf(i));
            } catch (Exception e) {
             // TODO Auto-generated catch block
             e.printStackTrace();
            }
    }
    });
  }
}

here is my imageAdapter file.

public class ImageAdapter extends BaseAdapter {
List<Item> items = new ArrayList<Item>();
private LayoutInflater inflater;

public ImageAdapter(Context context) {
    inflater = LayoutInflater.from(context);

    items.add(new Item("One",       R.drawable.abstact_one));
    items.add(new Item("Two",   R.drawable.abstract_three));
    items.add(new Item("Three", R.drawable.image_two));
    items.add(new Item("Four",      R.drawable.image_four));
    items.add(new Item("Five",     R.drawable.image_five));
    items.add(new Item("Six",      R.drawable.image_nine));
    items.add(new Item("Seven",       R.drawable.image_ten));
}

@Override
public int getCount() {
    return items.size();
}

@Override
public Object getItem(int i) {
    return items.get(i);
}

@Override
public long getItemId(int i) {
    return items.get(i).drawableId;
}

@Override
public View getView(int i, View view, ViewGroup viewGroup) {
    View v = view;
    ImageView picture;
    TextView name;

    if(v == null) {
        v = inflater.inflate(R.layout.other, viewGroup, false);
        v.setTag(R.id.picture, v.findViewById(R.id.picture));
        v.setTag(R.id.text, v.findViewById(R.id.text));
    }

    picture = (ImageView)v.getTag(R.id.picture);
    name = (TextView)v.getTag(R.id.text);

    Item item = (Item)getItem(i);

    picture.setImageResource(item.drawableId);
    name.setText(item.name);

    return v;
}

private class Item {
    final String name;
    final int drawableId;

    Item(String name, int drawableId) {
        this.name = name;
        this.drawableId = drawableId;
    }
 }
}

      GridView gridView = (GridView) findViewById(R.id.grid_view);

        // Instance of ImageAdapter Class

                    int position, long id) {

                // Sending image id to FullScreenActivity
                Intent i = new Intent(getApplicationContext(), FullImageActivity.class);
                // passing array index
                i.putExtra("id", position);
                startActivity(i);

In your LatestTab

Declare the list as a class member

  List<Item> items = new ArrayList<Item>();

Add the items to the list

items.add(new Item("One", R.drawable.abstact_one));
items.add(new Item("Two",  R.drawable.abstract_three));
items.add(new Item("Three", R.drawable.image_two));
items.add(new Item("Four", R.drawable.image_four));
items.add(new Item("Five", R.drawable.image_five));
items.add(new Item("Six",  R.drawable.image_nine));
items.add(new Item("Seven", R.drawable.image_ten));

Your Item class

public class Item {
String name;
int drawable;
public int getDrawable() {
    return drawable;
}
public void setDrawable(int drawable) {
    this.drawable = drawable;
}
public Item(String name, int id)
{
    this.name= name;
    this.drawable = id;
}
public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

}

Pass the list to the constructor of adapter class

 gridView.setAdapter(new ImageAdapter(this,items));

In the constructor

  List<Item> items;
  public ImageAdapter(Context context,List<Item> items) {
   inflater = LayoutInflater.from(context);
   this.items = items;
 } 

then in getVIew

 Item item = (Item)items.get(i);
 picture.setImageResource(item.getDrawable());

Then in item click listener

  Item item = items.get(position);
  int  id = item.getDrawable(); 
  Intent i = new Intent(getApplicationContext(), FullImageActivity.class);
  i.putExtra("idkey", id); // pass the id
  startActivity(i);

Then in FullImageActivity

  int id = getIntent().getIntExtra("idkey"); //get id
  imageview.setImageResource(id); // set the drawable to imageview
