问题
I am making a number of imageViews programmatically in a loop and assigning them ids. But when in onClick method I need to get the id of images, it is returning the id of the last image only. How do I get the id of the image that is clicked?
The code I am using:
for (int j = 0; j < 5; j++) {
TableRow tr = new TableRow(this);
imageUrl = "http://ondamove.it/English/images/users/";
imageUrl = imageUrl + listObject.get(j).getImage();
image = new ImageView(this);
image.setPadding(20, 10, 0, 0);
image.setId(j+1);
tr.addView(image);
try {
new DownloadFileAsync(image, new URL(imageUrl))
.execute(imageUrl);
images.add(image);
//images = new ImageView[5];
}
catch (Exception e) {
e.printStackTrace();
}
tr.addView(image);
table.addView(tr, new TableLayout.LayoutParams(
LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
image.setOnClickListener(clickImageListener);
Following is the onclicklistener.
private OnClickListener clickImageListener = new OnClickListener() {
public void onClick(View v) {
imageId = image.getId();
Intent fullScreenIntent = new Intent(v.getContext(),FullImageActivity.class);
fullScreenIntent.putExtra(ProfilePageNormalUser.class.getName(),imageId);
ProfilePageNormalUser.this.startActivity(fullScreenIntent);
}
};
回答1:
Inside the onClick(View v) method you can call v.getId() - this will return you the ID of the View being clicked. Hope this helps.

Try this out:
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
int index = 0;
for (int i = 0; i < image.length; i++)
{
if (image[i].getId() == v.getId())
{
index = i;
break;
}
}
Toast.makeText(this, "Image clicked index => "+index, Toast.LENGTH_SHORT).show();
}
