How to make value to be fixed and highlight in center while scrolling

I have a requirement to create UI like below
You can see here the number is the highlighted part and it is in center always.
And we scroll it from left to right or vice versa.
I want to achieve this So, I wrote some code like below. But I don't have any Idea on how to add scroll effect to it and bring highlighted text to center
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
app:layout_constraintBottom_toTopOf="#+id/idCameraControlBottom"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent">
<TextView
android:id="#+id/idZoom1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginEnd="50dp"
android:text="."
android:textAlignment="textEnd"
android:textSize="20sp"
android:textStyle="bold" />
<TextView
android:id="#+id/idZoom2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginEnd="50dp"
android:background="#drawable/circle_shade"
android:gravity="center"
android:text="1X"
android:textSize="16sp" />
<TextView
android:id="#+id/idZoom3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="."
android:textAlignment="viewStart"
android:textSize="20sp"
android:textStyle="bold" />
</LinearLayout>
Any Idea/Help is greatly appreciated.

You can create it like so:
<RelativeLayout
android:layout_centerInParent="true"
android:layout_width="100dp"
android:layout_height="wrap_content">
<HorizontalScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="1"/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="1"/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="1"/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="1"/>
</LinearLayout>
</HorizontalScrollView>
<TextView
android:layout_centerInParent="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#000"
android:textColor="#fff"
android:text="1"/>
</RelativeLayout>
Change it as you see fit, basically, the relative layout parent holds within the horizonal scrollable scrollview, within it you have your needed-to-be-scrolled views. After if you define your number view, being inside a relative layout it will simply be ordered above it. You can then center it to appear above your scrollable scrollView.
Do note the following 2 this:
The scroll will only be performed if the user touched the scrollable view. As in, if the user tries to swipe from pressing on the number it self, it will not scroll.
The content behind the number will be hidden behind it, it won't "skip" from 1 side to the other so you can have "invisible" content that way.

You can see my included layout comes after the button but in the picture you can see it's actually beneath the button. Please help with a solution. Also except the included layout all the views are in a chain.

Go to your xml, click design. The on the upper left, corner you will see an icon similar to a blueprint. Click on it and you will get your layout as a blue print. Then click on the element that you want, you will see four points on all sides. Click on the upper point and drag it to the upper bar(menu, etc.). That way you will attach it and it will stay in place. If you want to make offset look on you right above the properties you will see a box representing the item with its constraints, just put the distance you want, and you will have your offset.

The problem was in Android 5.0 elevation is introduced. A button has a default elevation that's why it was always showing on top. Setting elevation value to my include layout solve the problem.

FrameLayout inside RelativeLayout not showing

I have the following issue. In my layout, which is used as a list item, I have a FrameLayout inside a RelativeLayout. In the Graphical Layout in Eclipse it appears just as expected, however, when I debug in a real device (HTC One V Android 4.0.3 in this case), the FrameLayout does not appear at all (but the area it occupies is visible). In the Adapter I do not play with the visibility, I just change the background color between two colors.
Here is my layout code:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

</RelativeLayout>
In my adapter, the part where I interact with the layout for changing the color (and I assure you is the only part of the code where I interact with the R.id.entryType view), I have the following code:
if(entry.isInEntry())
viewHolder.entryType.setBackgroundColor(getContext().getResources().getColor(R.color.color_punch_in_darker));
else
viewHolder.entryType.setBackgroundColor(getContext().getResources().getColor(R.color.color_punch_out_darker));
The Graphical layout shows the following, which is the correct
But when I debug, the following appears (the arrow and the border shows the area where the color should be, but instead only the width appears)
Many thanks in advance since I do not know what else I can check.

Use foreground attribute for FrameLayout (with no children) instead of background
or add a View (fill_parent) to the FrameLayout
or set the FrameLayout's paddingLeft to 15dp (same as your width)
FrameLayout will measure itself as 0 unless it has a reason to give itself dimension. The layout_widith/height is still reserving it space, but it has no children to draw and your background is a color (therefore it's dimensionless)

try layout_alignParentLeft="true", add some margin for testing for Framelayout and then have the textboxes in reference to that

TextView not scrolling Smoothly

I am trying to scroll my textview using the following code:
TextView text = (TextView) findViewById(R.id.textView12);
text.setMovementMethod(ScrollingMovementMethod.getInstance());
int height = getResources().getDrawable(R.drawable.pic_ground_pranic).getIntrinsicHeight();
text.setLayoutParams(new FrameLayout.LayoutParams(LayoutParams.FILL_PARENT, height));
text.setText("As part of an Android App I am building a button set.For performance reasons and to keep the code simpler, the Android system uses pixels as the standard unit for expressing dimension or coordinate values. That means that the dimensions of a view are always expressed in the code using pixels, but always based on the current screen density. For instance, if myView.getWidth() returns 10, the view is 10 pixels wide on the current screen, but on a device with a higher density screen, the value returned might be 15. If you use pixel values in your application code to work with bitmaps that are not pre-scaled for the current screen density, you might need to scale the pixel values that you use in your code If you need to control exactly how your application will look on various screen configurations, adjust your layouts and bitmap drawables in configuration-specific resource directories. For example, consider an icon that you want to display on medium and high density screens. Simply create your icon at two different sizes (for instance 100x100 for medium density and 150x150 for high density) and put the two variations in the appropriate directories, using the proper qualifiers: For instance, suppose a device has a WVGA high-density screen, which is 480x800 and about the same size as a traditional HVGA screen, but it's running an application that has disabled pre-scaling. In this case, the system will lie to the application when it queries for screen dimensions, and report 320x533 (the approximate mdpi translation for the screen density). Then, when the application does drawing operations, such as invalidating the rectangle from (10,10) to (100, 100), the system transforms the coordinates by scaling them the appropriate amount, and actually invalidate the region (15,15) to (150, 150). This discrepancy may cause unexpected behavior if your application directly manipulates the scaled bitmap, but this is considered a reasonable trade-off to keep the performance of applications as good as possible. If you encounter this situation, read Based on the density of the current screen, the system uses any size- or density-specific resources from your application and displays them without scaling. If resources are not available in the correct density, the system loads the default resources and scales them up or down as needed to match the current screen's density. The system assumes that default resources (those from a directory without configuration qualifiers) are designed for the baseline screen density (mdpi), unless they are loaded from a density-specific resource directory. Pre-scaling is, thus, what the system does when resizing a bitmap to the appropriate size for the current screen density. to match the un-scaled bitmap source. The buttons are part of a nested set of LinearLayouts.The question then is: How to resize the layout.I have tried several suggested techniques, and none come close to working. Here is a subset of the XML that builds the button set:");
All is working fine but my text view is not scrolling smoothly. I thought I have to put my Textview inside a Scrollview but this is also not working.
Does it happen because I am resizing my textview?
Please provide any solution for this problem. I already spent a lot of time on this.

Thanks in advance!

In my case I just needed to put my TextView inside a ScrollView. Scrolling got very smooth and users lived happily every after!
<ScrollView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:fillViewport="true"
>
<TextView
android:id="#+id/textview_about"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textIsSelectable="true"
android:textSize="20dp" />
</ScrollView>

problem is ScrollView inside ScrollView.
When you put ScrollView inside ScrollView android just get confused which scroll view is touched. So sometimes it gets unable to deliver touch event.
After searching for a time I found a link or blog that will extract this problem and also have solution.
Take a look at this blog. This is exactly what you have been searching for and i am sure that it will solve your problem.
Now time to Enjoy ;)

The TextView scroll only if you restrict its height. Simple rule is when the text is more then the available space then textview start scrolling.
One way is what you are following by assigning a fixed height which you got from some image size. One other way is by setting the maximum number of lines.
TextView text = (TextView) findViewById(R.id.textView12);
text.setMaxLines(5);
text.setMovementMethod(ScrollingMovementMethod.getInstance());
you can even make it more dynamic. Simply by calculating number of lines.
Number of lines = (image Height in pixels)/(text font size in pixel)

First of all there is no need of the setting the Layoutparams as because you have give it in to the xml layout.
And if you have such long string then dont put it directly on java code. Instead of it put that string to the resources directory.
go to values, and open strings.xml file and define your string.
See below:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="hello">Hello World, HelperStackOverflowActivity!</string>
<string name="app_name">HelperStackOverflow</string>
<string name="String1">"PUT YOUR STRING HERE" </string>
</resources>
After doing that set the string in Java code whenever you want.
as like:
text = (TextView)findViewById(R.id.textView12);
text.setText(getResources().getString(R.string.String1));
it Scroll nice as normal scrolling.
Hope it will help you.
Enjoy. :)

align text center with android

I know it sounds easy. I need to put a text in center, but when the text is too long it needs to go below, but still align in the center of my xml.
Here's my code :
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/showdescriptioncontenttitle"
android:paddingTop="10dp"
android:paddingBottom="10dp"
android:layout_centerHorizontal="true"
>
<TextView
android:id="#+id/showdescriptiontitle"
android:text="Title"
android:textSize="35dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
</LinearLayout>
I put paddingTop and Bottom because I need some space.
PS: My code is bigger; it's in a RelativeLayout.

Set also android:gravity parameter in TextView to center.
For testing the effects of different layout parameters I recommend to use different background color for every element, so you can see how your layout changes with parameters like gravity, layout_gravity or others.

use this way
txt.setGravity(Gravity.CENTER);

use this way in xml
<TextView
android:id="#+id/myText"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Time is precious, so love now."
android:gravity="center"
android:textSize="30dp"
android:textColor="#fff"
/>

You can use the following:
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/showdescriptioncontenttitle"
android:paddingTop="10dp"
android:paddingBottom="10dp">
<TextView
android:id="#+id/textview1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:text="Your text"
android:typeface="serif" />
</LinearLayout>
The layout needs to be relative for the "center" property to be used.

Adding android:gravity="center" in your TextView will do the trick (be the parent layout is Relative/Linear)!
Also, you should avoid using dp for font size. Use sp instead.

Just add these 2 lines;
android:gravity="center_horizontal"
android:textAlignment="center"

add layout_gravity and gravity with center value on TextView
<TextView
android:text="welcome text"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center"
android:gravity="center"
/>

android:layout_gravity="center"
or
android:gravity="center"
both works for me.

Or check this out this will help align all the elements at once.
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/showdescriptioncontenttitle"
android:paddingTop="10dp"
android:paddingBottom="10dp"
android:layout_gravity="center"
android:gravity="center_horizontal"
>
<TextView
android:id="#+id/showdescriptiontitle"
android:text="Title"
android:textSize="35dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
</LinearLayout>

If you want to change the alignment from the mainActivity.java file, then use the gravity. For example:
chatMsg.setGravity(Gravity.RIGHT);
chatMsg is my textView. I wanted the text to be right aligned and this code worked well.

you can easily done this by adding these lines
android:layout_width="match_parent"
android:gravity="center"
android:textAlignment="center"
