    I need to develop one android application. What I need here is, when I click on ImageView, size of text size automatically increased. How can I do this?

    I have used below code:

    [HIGH]String title = in.getStringExtra("Title");
    lblName = (TextView) findViewById(R.id.title);
    lblName.setText(title);
    ImageView positive = (ImageView) findViewById(R.id.imageView3);
    positive.setOnClickListener(new OnClickListener() {
    public void onClick(View v) {
    lblName.setTextSize(TypedValue.COMPLEX_UNIT_PX, lblName.getTextSize() + 2);
    }
    }); [/HIGH]

    Here the textSize is increased well on TextView..how can i increase the textSize on android webview...

    please give me solution for these ???

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

    How can i increase the textSize for these description ????

    I have added below code:

    [HIGH]WebSettings webSettings = des.getSettings();
    webSettings.setTextSize(WebSettings.TextSize.SMALLEST);
    [/HIGH]

    I have to run the app which means am getting the text is smallest fontsize.but i wish to increase the fontsize while clicking imagview automatically...

    NOTE:

    Please see https://itunes.apple.com/gb/app/bbc-news/id377382255?mt=8. See the 2nd image at bottom -A and +A image is there. Clicking that images means automatically increase and decrease the whole app textview font size. How can I do this in android app?
