Android，如何将int变量的名称传递给popupwindow？

Question

How can I pass the name of an int variable to a popupwindow when an image is clicked? I have set an int per image and I have a lot of images that I had set.

This is how I'm using the int in a textView on a PopupWindow.

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);

}
 }

Could you explain how you are setting the INT per image? Copying and pasting the code on how you set an INT per image would be helpful, because it's unclear what you mean by you are setting an INT per image.

Also, are you interested in the value of the int variable or the name of the variable? Showing how you are settings lots of images with int per image would help clarify what you are trying to do.

-- adding answer after seeing the updated post with code --

I would create an object that has the name you are interested in (ie intcount1) and an int to keep the actual value. After that, you can associate each button/ImaveView with that object with the view.setTag method, and get the value via view.getTag method. Here's an example:

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);
    }
}   

The bottom line is, creating an object with name/count value, associate each View with its own object using the view.setTag() function, and when you need to read the values, use the view.getTag() to get the object and read the mTagName (the "variable" name) and the mCount (the "variable" value).
