好吧,我已经动态创建了图像。图像是随机的。我想要做的是确定img的字符串名称是什么,因为我想将字符串名称与动态创建的字符串名称进行比较。这必须在onTouch上实施。这是可能的感谢查找动态创建的所选img的字符串值
我希望我足够描述。
我下面
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
}
检索但我怎么确定哪些我点击放置该context.getRe来源()。getResourceEntryName(imageResID); ... –
你从哪里得到图像?可绘制文件夹还是什么? –
img来自随机生成的可绘制文件夹。我只想确定什么是触摸/拖动...它的字符串值...基本上基于从可绘制文件夹中生成的img,我想启动DURING onTouch来查看当前正在选择的内容img ..字符串它的名字 –
