多個按鈕，試圖井井有條

Question

我執行在片段Tab3Fragment一個彈出式窗口，想保持在彈出的代碼，

public void showPopup(View anchorView){ 
} 

，並在其他地方Tab3Fragment最小化，儘可能以保持整潔。

目前showPopup看起來像這樣，

public void showPopup(View anchorView) {  
    Button btnDismiss, btnFirstRecord, btnPreviousRecord, btnNextRecord, btnLastRecord; 
    LayoutInflater layoutInflater = (LayoutInflater)getActivity().getSystemServi (Context.LAYOUT_INFLATER_SERVICE); 
    View popupView = layoutInflater.inflate(R.layout.popup_layout, null); 
    final PopupWindow popupWindow = new PopupWindow(popupView, LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);  
    TextView tv = (TextView)popupView.findViewById(R.id.tv); 
    tv.setText("Blah, blah, blah"); 

    btnDismiss = (Button)popupView.findViewById(R.id.btnDismissxml); 
    btnFirstRecord = (Button)popupView.findViewById(R.id.btnFirstRecordxml); 
    btnPreviousRecord = (Button)popupView.findViewById(R.id.btnPreviousRecordxml); 
    btnNextRecord = (Button)popupView.findViewById(R.id.btnNextRecordxml); 
    btnLastRecord = (Button)popupView.findViewById(R.id.btnLastRecordxml); 

    popupWindow.setFocusable(true); 
    int location[] = new int[2]; 
    anchorView.getLocationOnScreen(location); 
    popupWindow.showAtLocation(anchorView, Gravity.CENTER, 0, 0); 
    } 
} 

問題：有什麼辦法來實現showPopup的中的onClick方法的情況下，switch語句，將處理呢？也許類似，

@Override 
public void onClick(View v) {  
    switch (v.getId()) { 
    case R.id.btnFirstRecordxml: 
     //firstRecord(v); 
     break; 
    case R.id.btnPreviousRecordxml: 
     //previousRecord(v); 
     break; 
    case R.id.btnNextRecordxml: 
     //nextRecord(v); 
     break; 
    case R.id.btnLastRecordxml: 
     //lastRecord(v); 
     break; 
    case R.id.btnDismissxml: 
     //closePopup(v); 
     break; 
    }} 

其他解決方案如把中的onClick正是如此popup_layout.xml，

<Button 
    android:id="@+id/btnFirstRecordxml" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:text="@string/pszFirstRecordButton" 
    android:onClick="Tab3Fragment.firstRecord"/> 

處理按鈕點擊將高度讚賞。在此先感謝...

更新，11月23日2014年 這裏是不工作的多個按鈕的代碼showPopup（）的解決方案。我會在彈出的幾個按鈕....

private void showPopup(){ 
    LayoutInflater layoutInflater = (LayoutInflater)getActivity().getSystemService(Context.LAYOUT_INFLATER_SERVICE);  
    View popupView = layoutInflater.inflate(R.layout.popup_layout, null); 
    Button btnDismiss=(Button)popupView.findViewById(R.id.btnDismissxml); 
    Button btnSaveRecord=(Button)popupView.findViewById(R.id.btnSaveRecordxml); 
    final PopupWindow popupWindow=new PopupWindow(popupView,480,500,true); 
    popupWindow.showAtLocation(popupView, Gravity.CENTER, 0, 40);         
//first button 
    btnSaveRecord.setOnClickListener(new OnClickListener() { 
     @Override 
     public void onClick(View arg0) { 
      // TODO Auto-generated method stub 
      saveRecord(); 
     } 
    }); 
//second button 
    btnDismiss.setOnClickListener(new OnClickListener() { 
     @Override 
     public void onClick(View arg0) { 
      // TODO Auto-generated method stub 
      popupWindow.dismiss(); 
     } 
    }); 
} 

任何方式來插入case-switch結構，以允許showPopup（）中的其他按鈕代碼？這將避免爲每個按鈕創建單獨的onClickListener-onClicks，如上所示。

Answer 1

修改這樣的XML，使用android:onClick="ClickEvent"這個formet中的所有按鈕

<Button 
android:id="@+id/btnFirstRecordxml" 
android:layout_width="fill_parent" 
android:layout_height="wrap_content" 
android:text="@string/pszFirstRecordButton" 
android:onClick="ClickEvent"/> 
<Button 
android:id="@+id/btnPreviousRecordxml" 
android:layout_width="fill_parent" 
android:layout_height="wrap_content" 
android:text="@string/pszPreviousRecordButton" 
android:onClick="ClickEvent"/> 

使用點擊funcationality這樣，

public void clickEvent(View v) 
{ 
    switch (v.getId()) { 
case R.id.btnFirstRecordxml: 
    //firstRecord(v); 
    break; 
case R.id.btnPreviousRecordxml: 
    //previousRecord(v); 
    break; 
case R.id.btnNextRecordxml: 
    //nextRecord(v); 
    break; 
case R.id.btnLastRecordxml: 
    //lastRecord(v); 
    break; 
case R.id.btnDismissxml: 
    //closePopup(v); 
    break; 
} 
} 

或者試試這個，

btn.setOnClickListener(btnaction);組像這聽衆的所有按鈕，

OnClickListener btnaction = new OnClickListener() { 
    @Override 
    public void onClick(View v) { 
    //use the switch conditons... 
    } 
}; 
btn1.setOnClickListener(btnaction); 
btn2.setOnClickListener(btnaction); 

Answer 2

public void showPopup(View anchorView) {  
    Button btnDismiss, btnFirstRecord, btnPreviousRecord, btnNextRecord, btnLastRecord; 
    LayoutInflater layoutInflater = (LayoutInflater)getActivity().getSystemServi (Context.LAYOUT_INFLATER_SERVICE); 
    View popupView = layoutInflater.inflate(R.layout.popup_layout, null); 
    final PopupWindow popupWindow = new PopupWindow(popupView, LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);  
    TextView tv = (TextView)popupView.findViewById(R.id.tv); 
    tv.setText("Blah, blah, blah"); 

    btnDismiss = (Button)popupView.findViewById(R.id.btnDismissxml); 
    btnFirstRecord = (Button)popupView.findViewById(R.id.btnFirstRecordxml); 
    btnPreviousRecord = (Button)popupView.findViewById(R.id.btnPreviousRecordxml); 
    btnNextRecord = (Button)popupView.findViewById(R.id.btnNextRecordxml); 
    btnLastRecord = (Button)popupView.findViewById(R.id.btnLastRecordxml); 

btnFirstRecord.setOnClickListener(new Listener()); 
btnPreviousRecord.setOnClickListener(new Listener()); 
btnNextRecord .setOnClickListener(new Listener()); 
btnLastRecord .setOnClickListener(new Listener()); 

    popupWindow.setFocusable(true); 
    int location[] = new int[2]; 
    anchorView.getLocationOnScreen(location); 
    popupWindow.showAtLocation(anchorView, Gravity.CENTER, 0, 0); 
    } 
} 


Class Listener implements OnClickListener 
{ 
@Override 
     public void onClick(View v) { 
switch (v.getId()) { 
    case R.id.btnFirstRecordxml: 
     //firstRecord(v); 
     break; 
    case R.id.btnPreviousRecordxml: 
     //previousRecord(v); 
     break; 
    case R.id.btnNextRecordxml: 
     //nextRecord(v); 
     break; 
    case R.id.btnLastRecordxml: 
     //lastRecord(v); 
     break; 
    case R.id.btnDismissxml: 
     //closePopup(v); 
     break; 
    } 

} 

}
