How to get the image name of the ImageView in Android?

问题

I have an imageview in android . I want to get the name of the image which is set in the in the imageview. How can I do that ?

ImageView v = (ImageView)findViewbyId(R.id.img);
//String name = findImageName(v);
if( name.equals(a))
{
   //do something
} 
else{
   //do something
}

回答1:

For this first of all you need to set a tag for your ImageView

<ImageView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/imageview1" 
    android:background="@drawable/bg1"
    android:tag="bg1"/>

Now get the image name currently set on your ImageView by doing the following,

ImageView v = (ImageView)findViewbyId(R.id.img);
String backgroundImageName = String.valueOf(v.getTag());

and this should return the image tag name which is "bg1".

Now compare the tag names or use it for further process

if( backgroundImageName.equals(bg1))
{
   //do something
} 
else{
   //do something
}

You can set the name ussing tag.

imageView.setTag("any name")

And retrieve the value using

String imageNameName = (String) imageView.getTag();

回答3:

    ImageView img = (ImageView) findViewById(R.id.imageView);
    String imageName = img.getContentDescription();

回答4:

Couldn´t you use something like this?

ImageView v = (ImageView)findViewbyId(R.id.img);
if(R.id.someId == v.getId())
{
   //do something
} 
else{
   //do something
}

It´s easier than use resources' names.
