使用SimpleCursorAdapter的OnClickListener的getView（）

希望你很好。我搜索了更多關於如何在getView（）方法中實現OnclickListener的方法，但這仍然沒有實現，我想通過單擊位於ListView內的按鈕來執行一個操作。這是我的代碼。使用SimpleCursorAdapter的OnClickListener的getView（）

public class Restaurant extends Activity { 
private DatabaseHandler myDatabaseHandler; 
ListView listContent; 
Context context; 
TextView rest_name; 
TextView rest_hotline; 
ImageButton call; 
ImageView rest_image; 
String image_string; 
String r_n = ""; 
String r_e = ""; 
String r_h = ""; 
private CursorAdapter dataSource; 
RelativeLayout resta; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_restaurant); 
     listContent = (ListView)findViewById(R.id.restaurants_list); 
     call = (ImageButton) findViewById(R.id.call); 

     /* 
     * Create/Open a SQLite database 
     * and fill with dummy content 
     * and close it 
     */ 
     myDatabaseHandler = new DatabaseHandler(this); 
     myDatabaseHandler.openToWrite(); 
     myDatabaseHandler.deleteAll(); 

     myDatabaseHandler.insert("First","1111",R.drawable.ic_launcher); 
     myDatabaseHandler.insert("Second","0000",R.drawable.ic_launcher); 
     myDatabaseHandler.close(); 

     /* 
     * Open the same SQLite database 
     * and read all it's content. 
     */ 
     myDatabaseHandler = new DatabaseHandler(this); 
     myDatabaseHandler.openToRead(); 

     Cursor cursor = myDatabaseHandler.queueAll(); 
     startManagingCursor(cursor); 
     String[] from = new String[]{DatabaseHandler.KEY_REST_NAME,DatabaseHandler.KEY_REST_HOTLINE, DatabaseHandler.KEY_REST_IMAGE}; 
     int[] to = new int[]{R.id.rest_name,R.id.rest_hotline, R.id.rest_image}; 

     final ListAdapter cursorAdapter = new SimpleCursorAdapter(this, R.layout.lists, cursor, from, to); 

     listContent.setAdapter(cursorAdapter); 
     myDatabaseHandler.close(); 
} 
private class CustomCursorAdapter extends SimpleCursorAdapter { 

    public CustomCursorAdapter(Context context, int layout, Cursor c, 
      String[] from, int[] to) { 
     super(context, layout, c, from, to); 
     // TODO Auto-generated constructor stub 
    } 
     class ViewHolder { 
     ImageButton b; 
    } 
    public View getView(final int position, View convertView, ViewGroup parent) 
    { 
     View view = convertView; 
     ViewHolder holder; 
     if(view == null) { 
      LayoutInflater vi = (LayoutInflater)getBaseContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
       view = vi.inflate(R.layout.lists, null); 
     holder = new ViewHolder(); 
     holder.b = (ImageButton) view.findViewById(R.id.call); 
     view.setTag(holder); 
     } 
     else 
     { 

      holder = (ViewHolder) view.getTag(); 
     holder.b.setOnClickListener(new View.OnClickListener() { 
      public void onClick(View v) { 
       // TODO Auto-generated method stub 
       Toast.makeText(getApplicationContext(),"ImageClickClick "+position, Toast.LENGTH_LONG).show(); 
      } 
     }); 
     } 
     return view;  
    }

你有什麼錯誤/結果？ – Simo

ImageButton在點擊時不起作用，無法執行我需要的操作。 –

其行B'coz您不使用CustomCursorAdapter

您正在使用

final ListAdapter cursorAdapter = new SimpleCursorAdapter(this, R.layout.lists, cursor, from, to);

，你給onClick動作裏面CustomCursorAdapter

holder.b.setOnClickListener(new View.OnClickListener() { 
      public void onClick(View v) { 
       // TODO Auto-generated method stub 
       Toast.makeText(getApplicationContext(),"ImageClickClick "+position, Toast.LENGTH_LONG).show(); 
      } 
     });

所以，你應該使用像

final CustomCursorAdapter cursorAdapter = new CustomCursorAdapter(this, R.layout.lists, cursor, from, to);

@AnasSherif爲什麼使用SimpleCursorAdapter？嘗試使用ArrayAdapter或BaseAdapter。您的CustomCursorAdapter實現不完整。 –

它現在有效，但數據應用於行！ –

好的，你可以給我一個使用ArrayAdapter或BaseAdapter的例子。 –

儘量去除其他statment在getView梅索德

我覺得代碼小姐對準使你的麻煩，試試這個方式...希望它能工作..

if(view == null) { 
    LayoutInflater vi = (LayoutInflater)getBaseContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
    view = vi.inflate(R.layout.lists, null); 
    holder = new ViewHolder(); 
    holder.b = (ImageButton) view.findViewById(R.id.call); 
    view.setTag(holder); 
} 
else 
{ 
    holder = (ViewHolder) view.getTag(); 

} 
holder.b.setOnClickListener(new OnClickListener() { 
    public void onClick(View v) { 
    // TODO Auto-generated method stub 
    Toast.makeText(getApplicationContext(),"ImageClickClick "+position, Toast.LENGTH_LONG).show(); 
} 
});

嘗試此

holder.b.setOnClickListener(new OnClickListener() { 

      @Override 
      public void onClick(View v) { 
       Toast.makeText(getApplicationContext(),"ImageClickClick "+position, Toast.LENGTH_LONG).show(); 

       } 

      } 
     });

或實現CustomCursorAdapter

private class CustomCursorAdapter extends SimpleCursorAdapter implements OnClickListener

並使用

@Override 
public void onClick(View v) { 
    // TODO Auto-generated method stub

Toast.makeText（getApplicationContext（），「ImageClickClicked」，Toast.LENGTH_LONG）.show（）;
