Answer 1

if u have already a button in ur app that will do the swap between the two pics u have when its clicked then there is a simple Code :D

// to add Images in android we simply " Copy them from their location and past in (res --> drawable)"

// then drag and drop "ImageView" and select the image u want to display

// u can adjust the scale throw "scaleType , layout_Width & layout_Height"

public boolean swap = true;

public  void change(View view)
{
    ImageView i = (ImageView) findViewById(R.id.img);
    if (swap)
    {
        i.setImageResource(R.drawable.images);
        swap=false;
    }
    else
    {
        swap=true;
        i.setImageResource(R.drawable.couple);
    }

}

Better solution, use the following xml as source of the image:

   <?xml version="1.0" encoding="utf-8"?>
    <selector xmlns:android="http://schemas.android.com/apk/res/android" >
        <item android:state_activated="true">
            <bitmap android:src="@drawable/image_selected"/>
        </item>
        <item>
            <bitmap android:src="@drawable/image_not_selected"/>
        </item>
    </selector>

    @Override
     public void onClick(View v) {
        v.setActivated(!v.isActivated());
     }

Answer 3

If you save the selection on click and then reload the image scroll gallery (or scroll menu) and then reload and scroll to the selection with a replaced image, then you might be able to do it. As far as I know none of the inbuilt gallery or menu functions have the ability to replace images once they are loaded and displayed.

What worked for me was:

I created a new drawable xml file, for eg, image_state.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true">
        <bitmap android:src="@drawable/image_pressed"/>
    </item>
    <item>
        <bitmap android:src="@drawable/image"/>
    </item>
</selector>

And in my layout file, I set the src of the imageView as:

<ImageView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/image_state"/>

don't forget to create the field "fun"

Try this for changing image.When imageview is pressed

Like_btn.setOnClickListener(new OnClickListener()
        {

            **private boolean fun = true;**


            public void onClick(View v)
            {
                if(fun)
                {
                Like_btn.setImageResource(R.drawable.unlike);
                fun=false;
                }
                else
                {
                    fun=true;       
                    Like_btn.setImageResource(R.drawable.like);
                    Toast.makeText(getApplicationContext(), "Changed", Toast.LENGTH_LONG).show();
                }
            }
        });

Answer 6

You want to do this.

ImageButton Demo_button = (ImageButton)findViewById(R.id.firstimage);

// when you click this demo button
Demo_button.setOnClickListener(new OnClickListener() {
    public void onClick(View v) {
        Demo_button.setImageResource(R.drawable.secondimage);
    }
}

Try this. (updated setset to set)
