How to identified which image is clicked in imageview - android

ImageView imageAd =(ImageView) findViewById(R.id.HomeimageViewAd);
ad4 and ad5 are changing on regular interval in imageAd (i.e imageview) and i want to find which image is click
//Image resource in an array
private int[] imageArray = {
R.drawable.ad4,
R.drawable.ad5
};
Bitmap bmp= BitmapFactory.decodeResource(getResources(),imageArray[i]);
imageAd.setImageBitmap(bmp);
imageAd.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// here i want to identified which image is clicked
} } );

Set id to imageviews like this
imageView.setId(imageArray[i]);
Then check with id.
The entire code will be like as follows
Bitmap bmp= BitmapFactory.decodeResource(getResources(),imageArray[i]);
imageAd.setImageBitmap(bmp);
imageAd.setId(imageArray[i]);
imageAd.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if(v.getId()==R.drawable.ad4){
}
} } );

How to handle touch event on a ImageView

I have three Images. When I first touch, first Image is shown, when I second touch, second Image is shown, and then when I third touch, third Image is shown. After all, when I fourth touch, I want to show first Image return and so on.
Can someone point me to show how handling or touching on a ImageView of android?
The below should do what you need:
public class MainActivity extends Activity {
ImageView image;
int i=1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
image = (ImageView) findViewById(R.id.imageViewName);
setButtonOnClickListeners();
}
}
image.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (i==1){
image.setImageResource(R.drawable.image1);
i++;
}
else if(i==2){
image.setImageResource(R.drawable.image2);
i++;
}
else if(i==3){
image.setImageResource(R.drawable.image3);
i++;
}
else if(i==4){
image.setImageResource(R.drawable.image4);
i=1;
}
}
});
I've not tested but the idea is correct. When you click the image it will change the drawable depending on the value of i. When you get image 1 i will equal 1. Onclick will increment i until i==4 which it will reset to 1 as you requested.
A while loop might be tidier but this was the quickest soultion I thought of.

You can simply set a View.OnClickListener for your ImageView:
imageView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// do stuff
}
});

Android is there ClickListener for linearLayout using addView?

I'm trying to create pinterest like layout. I find a way to achieve this: Android heterogeneous gridview like pinterest?!
However the problem is: I want to view item details after clicking each picture. But as I am using LinearLayout.addView() to add all the ImageViews, I'm not sure how I can get it clickable?
Is there anyway to be able to click each item on the view?
You can do this pretty easily by adding tag information to your image view that can be displayed when clicked.
Adding your image view would look like:
ImageView iv = new ImageView(context);
iv.setOnClickListener(your_listener);
iv.setTag("Item information");
linearLayout.addView(iv);
Then in your click listener:
public void onClick(View v) {
if(v instanceof ImageView) {
String info = (String)v.getTag();
/* Show information here */
}
}
Use this :
view.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// ADD your action here
}
});
or make your class implement the OnClickListner Interface and override the onClick() method
Use:
imageView.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
//do magic
}
});
And in your layout file mark the ImageView as clickable:
<ImageView
...
android:clickable="true">
...
</ImageView>
Building on the code that you linked, you can add a listener to each image view as you create it:
linear1 = (LinearLayout) findViewById(R.id.linear1);
linear2 = (LinearLayout) findViewById(R.id.linear2);
linear3 = (LinearLayout) findViewById(R.id.linear3);
for(int i=0;i<n;i++)
{
ImageView iv = new ImageView(this);
iv.setImageResource(R.id.icon);
iv.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
//Your click code
}
}
int j = count % 3; <----
if(j==0)
linear1.addView(iv);
else if(j==1)
linear2.addView(iv);
else
linear3.addView(iv);
}

//indicator.getActivePage();
LayoutInflater layoutInflater = (LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

System.out.println("helo i clicked==>"+c);
}
});
imageView3.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
System.out.println("helo i clicked==>"+c);
}
});
imageView4.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
System.out.println("helo i clicked==>"+c);
}
});
scroller.addPage(pageView);
}
It seem to be you didn't read information available at android developers.
Use below code to add onClickListener for images. I don't know whether you are using ImageView or ImageButton. I took ImageView.
ImageView iv = new ImageView(/**Context you have to pass**/);
iv.setOnClickListener(new View.OnClickListener) {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
// do whatever you want
}
});
I hope it may help you.
set this on your images..or button
in the xml such that
<Button [...]
android:onClick: "onClick" [...]
/>
"onClick": name this whatever you want your method name that handles clicks to be
This can be done by assigning onClickListeners to Image Buttons. You can use Image buttons to display these images and set onClickListeners on them. Perhaps something like this can help?
ImageButton button = (ImageButton) findViewById(R.id.imageButton1);
button.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// Do your stuff here
}
});
If you use ImageView then set the property OnClick to true.
