auto scroll in scrollview with speed

I want to auto-scroll lyrics on my app using ScrollView with speed control button. I have tried to animate the scrolling, but it didn't work.

For normal scrolling just set the
android:maxLines = "AN_INTEGER"
android:scrollbars = "vertical"
properties of your TextView in your layout's xml file.
Then use:
yourTextView.setMovementMethod(new ScrollingMovementMethod());
in your code.

Hide a partially visible line in a text view (Android)?

I have a textview with fixed height that contains text downloaded from a server. Sometimes the text is more than the view can wrap and it is cutting the extra text. The problem is that the last line the view can show is only partially visible which is kind of ugly.
Is there a way not to show a line if it is only partially visible?
android:maxLines wont help, because my layout has two textviews with different font sizes.

You can make textview scrollable. Add these lines :
android:maxLines = 'int' // put any integer value.
android:scrollbars = "vertical"

You can use android:ellipsize
android:ellipsize="end"
android:maxLines="1"
android:scrollHorizontally="true"
android:singleLine="true"

Try this one:
android:elegantTextHeight="true"

how to center android Textview element at bottom of the screen

I have the android xml layout using DroidDraw :
link : https://docs.google.com/document/d/1L3QJVwI9Znmeu1yANJXhDcZGFR70587d4oznu0hrZCw/edit?usp=sharing0
I need to bottom align the last Textview (Yellow one as indicated in the print screen).
i.e.
I need this :

Try using
android:alignParentBottom="true"
If I see correctly that the parent ViewGroup of your TextView is a RelativeLayout

Set the parent relative layout property to:
android:layout_gravity = "bottom | left"

In Relative layout use:
android:alignParentBottom="true"
and In Linear layout use:
android:layout_weight="1.0"
android:gravity="bottom|right"

This post did the trick.

I needed to implement layout_weight on my layouts. Basically defining weights for header, content and footer

how to add edittext to a linearlayout dynamically at desired positions to the linearlayout in android

I am new to android ,Actually i want to add edittexts to a relativelayout or linearlayout at desired positions on the layout .plz suggest me.
thanks in advance..

Do you really need add an EditText programmatically?
Usually it is enough to hide certain Views and change the visibility programmatically.
<EditText android:id="#+id/view_name"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:visibility="gone"
/>
The three values for visibility are "visible", "invisible" and "gone". "gone" means the EditText is taking no space. "invisible" means that the space it would take is empty.
You can change the visibility the following way:
EditText editText = (EditText) findViewById(R.id.view_name);
editText.setVisibility(View.VISIBLE);
