Android，如何將int變量的名稱傳遞給popupwindow？

Question

如何在點擊圖像時將int變量的名稱傳遞給popupwindow？我已經爲每個圖像設置了一個int，並且我有很多我設置的圖像。

這就是我在PopupWindow的textView中使用int的方式。

public boolean onLongClick(View v) { 
// v.setTag(v); 

case R.id.hsv1iv1: 
ImageView ivpopup = (ImageView) popupView.findViewById(R.id.pv1); 
intcount1++;   // I would like to pass this int name to the popup window. 
break; 
case R.id.hsv2iv1: 
ImageView ivpopup = (ImageView) popupView.findViewById(R.id.pv1); 
intcount2++;   // I would like to pass this int name to the popup window. 
break; 

LayoutInflater layoutInflater 
= (LayoutInflater)getBaseContext() 
.getSystemService(LAYOUT_INFLATER_SERVICE); 
View popupView = layoutInflater.inflate(R.layout.popup, null); 
final PopupWindow popupWindow = new PopupWindow(
popupView, 
LayoutParams.WRAP_CONTENT, 
LayoutParams.WRAP_CONTENT); 
popupWindow.update(0, 0, 800, 500); 
ColorDrawable dw = new ColorDrawable(-005500); 
popupWindow.setBackgroundDrawable(dw); 
tvpwlikectr = (TextView) popupView.findViewById(R.id.liketv); 


Button pwlikebtn = (Button) popupView.findViewById(R.id.pwlikebtn); 

Button btnDismiss = (Button)popupView.findViewById(R.id.cancel); 

pwlikebtn.setOnClickListener(new Button.OnClickListener() { 

public void onClick(View v) { 

intcount1++; 
tvpwlikectr.setText(Integer.toString(intcount1)); // this code doesn't work with the intcount1 

}}); 
btnDismiss.setOnClickListener(new Button.OnClickListener(){ 

public void onClick(View v) { 

popupWindow.dismiss(); 

popupWindow.setTouchable(true); 
popupWindow.setFocusable(true); 
popupWindow.setOutsideTouchable(true); 

} 
}

你能解釋一下你是如何設置每個圖像的INT？複製代碼並粘貼代碼，以便如何爲每個圖像設置INT會很有幫助，因爲您不清楚每個圖像設置的INT的含義。

另外，您是否對int變量的值或變量的名稱感興趣？顯示你是如何設置許多圖像與int每個圖像將有助於澄清你正在嘗試做什麼。

我會創建一個具有您所感興趣的名稱（即intcount1）和一個int，以保持實際值的對象。之後，您可以使用view.setTag方法將每個按鈕/ ImaveView與該對象相關聯，並通過view.getTag方法獲取該值。這裏有一個例子：

private class MyTag { 
    String mTagName; 
    int mCount; 
    MyTag(String tagName) { 
     mTagName = tagName; 
     mCount = 0; 
    } 
} 

// in your onCreate or initializaion code somewhere 
ImageView view1 = (ImageView) popupView.findViewById(R.id.hsv1iv1); 
MyTag imageTag = new MyTag("intcount1"); 
view1.setTag(imageTag); 
ImageView view2 = (ImageView) popupView.findViewById(R.id.hsv1iv1); 

// this will go wherever you handle the onLongClick 
public boolean onLongClick(View v) { 
    Object tag = v.getTag(); 
    if (tag instanceof MyTag) { 
     MyTag myTag = (MyTag) tag; 
     myTag.mCount++; 
    } 
} 

// I'm assuming you are setting the text from the actual clicked object 
// so this will go wherever you are setting the text/handling the click 
public void onClick(View v) { 
    Object tag = v.getTag(); 
    if (tag instanceof MyTag) { 
     MyTag myTag = (MyTag) tag; 
     myTag.mCount++; 
     tvpwlikectr.setText(myTag.mTagName); 
    } 
} 

底線是，以名稱/計數值創建一個對象，每個視圖與使用view.setTag（）函數自己的對象相關聯，當你需要閱讀的價值，使用view.getTag（）獲取對象並讀取mTagName（「變量」名稱）和mCount（「變量」值）。
