How to Change the background Image of a Layout when a button clicked

To show an Array of images as background, you need to create your Array, and an index to point to a position within your Array

private int[] images;  // declare your array in global scope
private int imagesIndex = 0;

Then you need to populate your Array with Drawable Resources. You can do it in onCreate() method(if using Array in `Activity).

int numOfImages = 4;
images = new int[numOfImages];
images[0] = R.drawable.ic_launcher_background;
images[1] = R.drawable.ic_launcher_foreground;
images[2] = R.drawable.fiona;
images[3] = R.drawable.shrek;

Finally in Click Listener of your Button you simply need to select a resource from your Array.

 @Override
 public void onClick(View v) {
     LinearLayout view = (LinearLayout) findViewById(R.id.layout1);
     view.setBackgroundResource(images[imagesIndex]); 
     ++imagesIndex;  // update index, so that next time it points to next resource
     if (imagesIndex == images.length - 1)
         imagesIndex = 0; // if we have reached at last index of array, simply restart from beginning.
  }

Change background on button click, using CSS only?

Based on the fiddle I posted in the comments I've modified it very slightly to use the Bootstrap button CSS.

Just include Bootstrap's CSS file then use the code below.

HTML

<label for="check" class="btn btn-default">Toggle background colour</label>
<input type="checkbox" id="check" />
<div></div>

CSS

div {
    width: 100%;
    height: 100%;
    background: #5CB85C;
    position: absolute;
    top: 0;
    left: 0;
    z-index: 1;
}
label.btn {
    position: absolute;
    top: 10px;
    left: 10px;
    z-index: 2; 
}
input[type="checkbox"]{
    display: none;
}
input[type="checkbox"]:checked + div{
    background: #5BC0DE;
}

This uses the adjacent sibling selector.

Here it is working: http://jsfiddle.net/eYgdm/ (I've added *-user-select: none; to prevent selection of the label text but it's not required for the label to work)

Browser support

Chrome, Firefox [Desktop & Mobile] (Gecko) ≥ 1.0, Internet Explorer ≥ 7, Opera ≥ 9 and Safari ≥ 3
