處理列表視圖OnItemClick服務中的事件

Question

我在android編程中遇到了一個問題，我需要從服務創建一個listview，listview工作正常，並按預期顯示項目。唯一的問題是我無法處理listview上的項目點擊事件。我試圖谷歌和找出一種方式，但沒有成功。我怎麼解決這個問題？以下是我的代碼，

@SuppressWarnings("unused") 
public class ContactsService extends Service implements OnClickListener, 
OnItemClickListener { 


private WindowManager mWindowManager; 
private View mChatHead; 
private LinearLayout mLayout, chatheadcontacts; 


private TextView hidetextView; 
private ImageView showView, cameraImageView; 


ListView contacts; 
public ArrayList<ContactListItem> contactsList; 
    LayoutInflater inflater; 


@Override 
public IBinder onBind(Intent intent) { 
return null; 
} 


// @SuppressLint("NewApi") 
@Override 
public void onCreate() { 
super.onCreate(); 


// Typeface tf = Typeface.createFromAsset(getAssets(), 
// "Roboto-Light.ttf"); 


mWindowManager = (WindowManager) getSystemService(WINDOW_SERVICE); 
Display display = mWindowManager.getDefaultDisplay(); 
/* 
* Point size = new Point(); display.getSize(size); screenWidth = 
* size.x; screenHeight = size.y; 
*/ 


inflater = LayoutInflater.from(this); 
mChatHead = inflater.inflate(R.layout.chathead, null); 
contacts = (ListView) mChatHead 
.findViewById(R.id.listView_chathead_contacts); 
mLayout = (LinearLayout) mChatHead 
.findViewById(R.id.chathead_linearlayout); 


chatheadcontacts = (LinearLayout) mChatHead 
.findViewById(R.id.chathead_contacts_layout); 


     cameraImageView = (ImageView)mChatHead.findViewById(R.id.chathead_imageView_camera); 
hidetextView = (TextView) mChatHead.findViewById(R.id.textViewhide); 
showView = (ImageView) mChatHead.findViewById(R.id.imageViewShow); 


// mChatHeadTextView.setTypeface(tf); 


contactsList = new ArrayList<ContactListItem>(); 
contactsList = getContacts(); 
final WindowManager.LayoutParams parameters = new WindowManager.LayoutParams(
WRAP_CONTENT, // Width 
LayoutParams.WRAP_CONTENT, // Height 
TYPE_PHONE, // Type 
WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE 
| WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE, // Flag 
PixelFormat.TRANSLUCENT // Format 
); 


parameters.gravity = Gravity.RIGHT; 


contacts.setAdapter(new CustomChatheadListAdapter(getBaseContext(), 
contactsList)); 
mWindowManager.addView(mChatHead, parameters); 
chatheadcontacts.setVisibility(View.GONE); 
hidetextView.setOnClickListener(this); 
showView.setOnClickListener(this); 
contacts.setOnItemClickListener(this); 
     cameraImageView.setOnClickListener(this); 
} 
@Override 
public void onItemClick(AdapterView<?> parent, View view, int position, 
long id) { 
Toast.makeText(getApplicationContext(), "Clicked "+position, Toast.LENGTH_SHORT) 
.show(); 


     Log.i("Clicked",""+position); 
// showPopup(); 
} 
} 

謝謝。

Answer 1

在您的activity中，聲明並引用您的列表視圖，而不是直接執行onItemClickListener。

然後，嘗試下面的代碼

listview.setOnItemClickListener(new OnItemClickListener(){ 


@Override 
public void onItemClick(AdapterView<?>adapter,View v, int position){ 

ItemClicked item = adapter.getItem(position); 

// do your action 

} 


}); 

在

您的適配器getItem你寫

public ItemClicked getItem(int position){ 

return items.get(position); 
}
