获取imageview的id
我正在循环中以编程方式创建多个 imageView 并为其分配 id。但是当在 onClick 方法中我需要获取图像的 id 时,它仅返回最后一个图像的 id。如何获取被点击的图片的id?
我正在使用的代码:
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);
以下是 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);
}
};
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);
}
};

在
onClick(View v)
方法中,您可以调用v.getId()
- 这将返回被单击的View
的 ID。希望这有帮助。Inside the
onClick(View v)
method you can callv.getId()
- this will return you the ID of theView
being clicked. Hope this helps.试试这个:
