private Button button1;
Drawable bitmapOrg;
private final int[] mColors =
{Color.BLUE, Color.GREEN, Color.RED, Color.LTGRAY, Color.MAGENTA, Color.CYAN,
Color.YELLOW, Color.WHITE};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
imageView = (ImageView)findViewById(R.id.imageView1);
button1 = (Button)findViewById(R.id.button1);
bitmapOrg = this.getResources().getDrawable(R.drawable.flower_blue);
button1.setOnClickListener(new OnClickListener() {
public void onClick(View view) {
int mColor = (int) Math.floor(Math.random() * mColors.length);
bitmapOrg.setColorFilter(mColors[mColor], PorterDuff.Mode.MULTIPLY);
imageView.setImageDrawable(bitmapOrg);
imageView.invalidate();
}
});
}

- create div with class with name e.g. circle
- create in styleSheet.css class circle
html code
<div class="circle" id="">3</div>
css code
.circle {
border-radius: 50%;
width: 50px;
height: 50px;
background: yellow;
position: absolute;
display: block;
border: 6px solid blue;
font-size: 50px;
text-align: center;
}

Toast in Android application is equivalent of Alert in JavaScript or MessageBox in WinApi.
// Toast android.widget.Toast.makeText(Context context, CharSequence text, int duration)
// public static Toast makeText (Context context, CharSequence text, int duration)
Toast.makeText(getApplicationContext(), "Hello world!",
Toast.LENGTH_SHORT).show();
