How can I draw text on a text view bottom up?

I need to draw text on a TextView in a bottom up fashion, i.e., draw the last line of the text first at the bottom, then the second last line of the text and so on. How can I do that?
I am trying to follow the solution given in this post - Paginating text in Android.
TextView draws the text top down. What I want to achieve is given a text, I would like the last line of the view filled first, then the second last line and so on, Hence filling the first line in the last iteration. I tried creating a Custom TextView and overriding its onDraw method, but nothing seems to work.

Create a custom textview. In the setText method, do some string manipulation. Basically rearranging the text in the string so that the first line I the new text string is the last line of the old text string. Pass the new text string to the super.setText

If it is not scrollable textview you can set android:gravity="bottom|left" or "bottom|right" if you want right alignment. With this method width and hight can't be wrap_content.

Imageview Background transparent

I set an image view on activity, but how can I remove the white space around the image view while image is .GIF?
' '

you need to have a background to the Button element, you can try and create a selector drawable and set it to the background of the button (assuming you want pres states)

Don't use imageview for png image. Use view or linerlayout.

How to Prevent TextWrapping programmatically?

How can I prevent a TextView, or any visual object, from wrapping to the screen and instead have them cropped programmatically?
I have a table view which is loaded with TextViews as cells. I need to crop the text inside the textview instead of wrapping.
Is there some code to do this? or is there any workaround?
For example, I have like this:
But what I want is:

I found my own way to fix this. I set the textView.SetMaxLines to 1 and it solved the problem for me.

You can use setSingleLine method:
TextView textView = (TextView) findViewById(...);
textView.setSingleLine(true);
and setEllipsize to remove ellipsize:
textView.setEllipsize(null);

Android Html.fromHtml in TextView - align image with text

I'm using Html.fromHtml to populate a textview. I want to align text right next to the img but the text seems to aligning with the bottom of the image. In html, you could assign an align attribute to the img tag and the text would align to the top of the image. But the align just seems to be ignored. Is there any way this can be achieved using the textview.
I cannot use a webview.

While probably it can't be solved with Html.fromHtml, you can have a LinearLayout and inside that an ImageView and a TextView, and then you can set alignments the way you want!

How to make a gallery with Image and text for android

I wanna make a Gallery, with a picture in the background and a textfield with invisible background... So I can see the text and the Image behind.
I already made the Gallery but i cant figure out how to put text in the foreground.

You create a custom adapter to use for your gallery view, see Hello Gallery tutorial
In the method getView() you have two different ways to achieve the same result:
A. Make an ImageView and a TextView and set the image and text:
ImageView iv = new ImageView(context); //and so on, remember to set the LayoutParams etc to fit your design.
Make a RelativeLayout and add the ImageView and TextView to it
Return the RelativeLayout.
B. Declare a layout in xml, with a RelativeLayout containing a TextView and an ImageView
In getView, inflate this layout, and using
inflatedLayout.findViewById(R.id.myTextView); //and so on
set the text and image and return the layout.
