Find the String value of a selected img created dynamically


Ok so I have dynamically created Images. the images are random. what i want to do is to identify what is the string name of the img because i want to compare the string name to something i created dynamically as well. this must be implemented on while on the onTouch. is this possible thanks

I hope i was descriptive enough.

my codes below

    Random rQuestion = new Random();
int iQues = rQuestion.nextInt(numQues - 1)+1;
corrImg = corrAnsIMPID[iQues]; //selectedImg has the string I want to      compare

ArrayList<String> quesList = new ArrayList<>();
quesList.add(corrAnsIMPID[iQues]);
quesList.add(myShuffledArray[rQuestion.nextInt(numQues - 1) + 1]);
quesList.add(myShuffledArray[rQuestion.nextInt(numQues - 1) + 1]);
quesList.add(myShuffledArray[rQuestion.nextInt(numQues - 1) + 1]);
Collections.shuffle(quesList);

String[] ranQues = new String[quesList.size()];
ranQues = quesList.toArray(ranQues);
for(String s : ranQues);  //contains the 4 string name of the img

//set 4 imgs
ImageView newView1 = new ImageView(this);
int id1 = getResources().getIdentifier(ranQues[0], "drawable", getPackageName());
newView1.setImageResource(id1);
//...repeated 4 times

public boolean onTouch (View v, MotionEvent ev)
{

if (mLongClickStartsDrag) return false;

boolean handledHere = false;

final int action = ev.getAction();

// In the situation where a long click is not needed to initiate a drag, simply start on the down event.
if (action == MotionEvent.ACTION_DOWN) {
   handledHere = startDrag (v);


    if (v != selectedImg mSpot2.setDragLayer (null);  //I want to compare if the selected img = corrImg.  this would activate/deactivate the drop zone

}

Solution

  • You can get the name of the resource from its id.

    String name = context.getResources().getResourceEntryName(imageResID);
    

    Get The resource id from the imageview again

    first set a tag

    imageView.setTag(R.drawable.yourDrawable); 
    

    then retrieve from that tag

    int resourceID = (int) imageView.getTag();
