Question

我有列表视图，其中包含图像，我想为每个图像打开活动。在我的代码中（来自一个例子）有Toast用于点击图像。我想把它改成开放活动，但我不知道怎么做。请帮我。这是我的代码：

public class ListOfAllAircraft extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(final Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.list_of_all_aircraft);

    final ArrayList<ItemDetails> image_details = GetSearchResults();

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

    lv1.setOnItemClickListener(new OnItemClickListener() {
        @Override
        public void onItemClick(final AdapterView<?> a, final View v, final int position, final long id) { 
            final Object o = lv1.getItemAtPosition(position);
            final ItemDetails obj_itemDetails = (ItemDetails)o;
            Toast.makeText(ListOfAllAircraft.this, "You have chosen : " + " " + obj_itemDetails.getName(), Toast.LENGTH_LONG).show();
        }  
    });
}

private ArrayList<ItemDetails> GetSearchResults(){
    final ArrayList<ItemDetails> results = new ArrayList<ItemDetails>();

    ItemDetails item_details = new ItemDetails();

    item_details.setImageNumber(1);
    results.add(item_details);

    item_details = new ItemDetails();
    item_details.setImageNumber(2);
    results.add(item_details);

    item_details = new ItemDetails();
    item_details.setImageNumber(3);
    results.add(item_details);

    item_details = new ItemDetails();
    item_details.setImageNumber(4);
    results.add(item_details);

    item_details = new ItemDetails();
    item_details.setImageNumber(5);
    results.add(item_details);

    item_details = new ItemDetails();

    item_details.setImageNumber(6);
    results.add(item_details);


    return results;
}
}

列表视图的onItemclicklistner中的

执行类似的操作。

 lv1.setOnItemClickListener(new OnItemClickListener() {
    @Override
    public void onItemClick(final AdapterView<?> a, final View v, final int position, final long id) { 


if(position == 0){

Intent intent = new Intent (ListOfAllAircraft.java, yourOtherActivityName1.class);
startActivity(intent);
}else if(position == 1){

Intent intent = new Intent (ListOfAllAircraft.java, yourOtherActivityName2.class);
startActivity(intent);

//.... and son

}

}  
});

也不要忘记在manifest File。
