Android 将ListView项（ImageView）显示给其他活动

我有一个带有ImageView和textView的简单列表视图

现在，每当我单击我的listItem时，我都需要将ImageView发送到另一个活动

我读了很多答案，但找不到更好的解决办法

这是我的lisview_items.xml：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content">

    <LinearLayout
                android:layout_width="wrap_content"
                android:layout_height="match_parent"
                android:orientation="vertical">
    <ImageView 
        android:id="@+id/photo"
        android:layout_width="150dip"
                android:layout_height="100dip"
        android:paddingRight="15dp"
        android:paddingLeft="15dp"/>
    </LinearLayout>
    <RelativeLayout
    android:layout_width="fill_parent"
               android:layout_height="match_parent"
               android:orientation="vertical"
               android:layout_marginLeft="160dp"
               android:layout_marginTop="10dp"
               android:descendantFocusability="blocksDescendants">
    <TextView android:id="@+id/name"
        android:textSize="14sp" 
        android:textStyle="bold" 
        android:textColor="#000000" 
        android:layout_width="wrap_content" 
        android:layout_height="wrap_content"/>
</RelativeLayout>
<RelativeLayout>

MyListView OnClick：

 ArrayList<ItemDetails> image_details = GetSearchResults();

    final ListView lv1 = (ListView) findViewById(R.id.list);
    lv1.setAdapter(new ItemListBaseAdapter(this, image_details));


    OnItemClickListener itemClickListener = new OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> a, View v, int position, long id) { 

            Object o = lv1.getItemAtPosition(position);
            ItemDetails obj_itemDetails = (ItemDetails)o;
            Toast.makeText(ListViewImagesActivity.this, "You have chosen : " + " " + obj_itemDetails.getName(), Toast.LENGTH_LONG).show();
            ProductName =obj_itemDetails.getName();
       }  
    };

以类似的方式，我如何发送上面所示的ArrayList中的图像..有人能告诉我此用法吗

您可以像处理名称一样将图像路径存储在

ItemDetails

对象上。然后，您可以通过

意图

将路径传递到新的

活动

如果图片在编译时可用，您可以像Gabe说的那样传递对其id的引用，而不是指向其位置的路径。

如果您实际切换到该活动，您可以在intent extras中传递图像的资源id，然后使用

getResources（）.getDrawable（id）

在那里。

您应该：

final ArrayList<ItemDetails> image_details = GetSearchResults();

final ListView lv1 = (ListView) findViewById(R.id.list);
lv1.setAdapter(new ItemListBaseAdapter(this, image_details));


OnItemClickListener itemClickListener = new OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> a, View v, int position, long id) { 

       ItemDetails selectedItem = image_details.get(position);
       //To-DO get you data from the ItemDetails Getter
      // selectedItem.getImage() or selectedItem.getName() .. etc 
      // the  send the data using intent when opening another activity 
      Intent intent = new Intent(CurrentActivity.this, DisplayImageActivity.class);
      intent.putExtra("image",selectedItem.getImage());
      intent.putExtra("name",selectedItem.getName()); 
      startActivty(intent);

   }  
};

SharedPreferences data = PreferenceManager.getDefaultSharedPreferences(getBaseContext());
data.edit().putString("SelectedProduct", ProductName).commit();

final ArrayList<ItemDetails> image_details = GetSearchResults();

final ListView lv1 = (ListView) findViewById(R.id.list);
lv1.setAdapter(new ItemListBaseAdapter(this, image_details));


OnItemClickListener itemClickListener = new OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> a, View v, int position, long id) { 

       ItemDetails selectedItem = image_details.get(position);
       //To-DO get you data from the ItemDetails Getter
      // selectedItem.getImage() or selectedItem.getName() .. etc 
      // the  send the data using intent when opening another activity 
      Intent intent = new Intent(CurrentActivity.this, DisplayImageActivity.class);
      intent.putExtra("image",selectedItem.getImage());
      intent.putExtra("name",selectedItem.getName()); 
      startActivty(intent);

   }  
};

@Override
public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      Intent i = getIntent();
      String image = i.getStringExtra("image");
      String name = i.getStringExtra("name");

}
