    [HIGH]String title = in.getStringExtra("Title");
    lblName = (TextView) findViewById(;
    ImageView positive = (ImageView) findViewById(;
    positive.setOnClickListener(new OnClickListener() {
    public void onClick(View v) {
    lblName.setTextSize(TypedValue.COMPLEX_UNIT_PX, lblName.getTextSize() + 2);
    }); [/HIGH]

    [HIGH]WebView des = (WebView) findViewById(;
    String description = in.getStringExtra("Description");
    des.loadDataWithBaseURL(null,description, "text/html", "UTF-8", null);[/HIGH]
