如何使用onListItemClick導航到Android中的另一個屏幕

Question

我對Android開發很陌生。您能否告訴我，如何使用onListItemClick導航到另一個屏幕。我在ListView有200項。如果我點擊ListView中的一個項目，它必須導航到另一個屏幕，該屏幕應顯示點擊項目的詳細信息。

我假設你正在從數據庫中獲取演員的列表和詳細信息。 我已經在我的應用程序中使用了相同的步驟來顯示所選食譜的食譜細節。

public class ActorList extends Activity { 

     ListView myActorList=null; 

public final static String selectedActor_ID="will Keep Actor ID"; 

     @Override 
     protected void onCreate(Bundle savedInstanceState) { 
      super.onCreate(savedInstanceState); 

     setContentView(R.layout.layout_actor_list);  

     //initialize controls 

      myActorList.setAdapter(adapter); 

      myActorList.setOnItemClickListener(new OnItemClickListener() { 

       @Override 
       public void onItemClick(AdapterView<?> arg0, View v, 
         int position, long id) { 
        // TODO Auto-generated method stub 


        Intent i= new Intent(ActorList.this,ActorDetail.class); 
        // you have to pass the actor id to next activity 
        // you can get this actor id from argument of type "long" 
        i.putExtra(selectedActor_ID, String.valueOf(id)); 
        startActivity(i); 

       }   

      }); 

    } 



} 


//Other Activity To show Detail.. 

//get the ID of Selected Actor on other activity say "ActorDetail" 

public class ActorDetail extends Activity { 



    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.layout_actor_detail); 

     ActorID=getIntent().getStringExtra(ActorList.selectedActor_ID); 
// now as you have the id here for that particular actor 
//fetch the detail of that selected actor thru id and bind it to your layout.  


    } 



}  

您需要註冊在清單文件中的其他活動也是這樣

<activity 
      android:name=".otherscreenActivity" 

     </activity>
