Parallelogram TextView in Android

I'm trying to create a parallelogram-shaped textview with some text inside (which has to be dynamic, based on some results retrieved from server). Up to now I extended TextView class implementing draw(Canvas canvas) method, I turned out into drawing the shape, but when I add my textView in xml and I try to add some text, the text simpy does not appear.
Here is my custom view:
public class ParallelogramTextView extends TextView {
Paint mInnerPaint;
public ParallelogramTextView(Context context) {
super(context);
init();
}
public ParallelogramTextView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
init();
}
public ParallelogramTextView(Context context, AttributeSet attrs) {
super(context, attrs);
init();
}
private void init() {
mInnerPaint = new Paint();
mInnerPaint.setAntiAlias(true);
mInnerPaint.setColor(Color.RED);
mInnerPaint.setStyle(Paint.Style.FILL);
mInnerPaint.setTextSize(20f);
}
#Override
public void draw(Canvas canvas) {
super.draw(canvas);
Path path = new Path();
path.moveTo(getWidth(),0);
path.lineTo(getWidth()/10, 0);
path.lineTo(0, getHeight());
path.lineTo(getWidth() - (getWidth()/10),getHeight());
path.lineTo(getWidth(), 0);
canvas.drawPath(path, mInnerPaint);
}
}
And here my xml:
<ParallelogramTextView
android:layout_width="200dp"
android:layout_height="40dp"
android:layout_gravity="center"
android:text="Test"
android:gravity="center"
android:textColor="#color/colorPrimary"
android:id="#+id/parallelogramTextView" />
I don't understand why text is not showing. Someone can help me?
Thanks in advance

I found a solution changing completely approach, I created a drawable representing a parallelogram shape using Vector and I used it as background for a normal TextView.
Don't know if it is best practice, but it worked for me.
Here the code of the drawable:
<vector xmlns:android="http://schemas.android.com/apk/res/android"
android:width="200dp"
android:height="50dp"
android:viewportWidth="200"
android:viewportHeight="50">
<path android:fillColor="#android:color/holo_red_dark"
android:pathData="M 200 0 L 20 0 L 0 50 L 180 50 L 200 0" />
</vector>

Android textview's view bounds are much larger than content, how to remove it?

My problem is, when i turn on a setting in the developer options to see view bounds, i can see that the orange "20" text wraps much larger space than it is requried. (top and bottom)
I tried to set: android:includeFontPadding="false" but it is just simple push up the content, leaving a big empty space bottom of the text's container.
How can i remove the extra space?
XML:
<LinearLayout
android:id="#+id/topDash"
android:layout_width="180dp"
android:layout_height="180dp"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:background="#drawable/circle_gray"
android:orientation="vertical" >
<TextView
android:id="#+id/RobotoTextView02"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="#string/sog_C"
android:textColor="#color/blue_medium"
android:textSize="20sp" />
<TextView
android:id="#+id/RobotoTextView01"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:gravity="center"
android:text="20"
android:textColor="#color/orange"
android:textSize="100sp" />
<TextView
android:id="#+id/robotoTextView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="KM/H"
android:textColor="#color/gray_darker"
android:textSize="24sp" />
</LinearLayout>

Very nice question. I'm not sure that it possible to do it only in XML and without setting any hard coded value for scrollY property, but I implemented a small custom class without hard coded values, which you can use without any modifications in other places. In such situations onMeasure method always come to help :) I use default font here. If you use different typeface, call textPaint.setTypeface() and set it before textPaint.getTextBounds statement.
public class CustomTextView extends TextView {
private int newWidth;
private int newHeight;
public CustomTextView(Context context) {
super(context);
}
public CustomTextView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public CustomTextView(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
}
#Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
if(newHeight == 0) {
Rect textBounds = new Rect();
Paint textPaint = new Paint();
textPaint.setTextSize(getTextSize());
textPaint.getTextBounds(getText().toString(), 0, getText().length(), textBounds);
int descent = (int) textPaint.descent();
newWidth = textBounds.width();
newHeight = textBounds.height() - 2 * descent;
setScrollY(descent);
}
setMeasuredDimension(newWidth, newHeight);
}
}
But this solution is only good for numbers, why only for numbers, because of descent, and that's why we cant remove that extra space ony inside the XML, it is a font property

Extending View class and layouts in Android

I am playing with layouts and views in Android. My layout looks like:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/LinearLayout1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<com.mycode.MyView
android:id="#+id/MyView"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
<LinearLayout
android:id="#+id/leftpane"
android:layout_width="55dp"
android:layout_height="wrap_content"
android:layout_weight="0.95"
android:background="#color/leftpane_background"
android:gravity="center"
android:orientation="vertical"
android:scrollbarStyle="insideOverlay" >
</LinearLayout>
</LinearLayout>
If i comment the lines <com.mycode.MyView .... />, the left linear layout (with id leftpane) is showed, otherwise not. If i add another layout after the leftpane layout (for example a scroll view layout), it does not get showed as well.
Why using my custom view (MyView) makes disappear all other layouts?
What i would like to do is to have my custom View for the background of the application, where i would show images, and some other view over the background, like scroll views, buttons and so on.
This is the code of MyView class. Keep in mind that i need to draw on the background of the activity an images (on the whole background, obviously not including the action bar):
/**
*/
class MyView extends View
{
TextPaint text_paint;
Paint paint;
private void InitView()
{
text_paint = new TextPaint( Paint.ANTI_ALIAS_FLAG );
text_paint.setColor( Color.BLACK );
paint = new Paint();
}
public MyView(Context context)
{
super(context);
InitView();
}
public MyView(Context context, AttributeSet attrs)
{
super(context, attrs);
InitView();
}
public MyView(Context context, AttributeSet attrs, int defaultStyle)
{
super(context, attrs, defaultStyle);
InitView();
}
#Override
protected void onDraw( Canvas canvas )
{
super.onDraw(canvas);
//int w, h;
//w = canvas.getWidth();
//h = canvas.getHeight();
//paint.setColor( Color.WHITE );
//canvas.drawRect(0, 0, w-1, h-1, paint );
//canvas.drawText( "ciao", 100, 100, text_paint);
}
};

Try to change your view's height as:
android:layout_height="wrap_content"

Maybe you did some error work when you overrode the onMeasure method in your custom MyView,
and so the MyView's match all the parent view.
Can you show your code which in the onLayout and onMeasure method of the MyView.

Remove space between stacked TextViews

I have a vertical LinearLayout with two TextView inside it. The former contains a static text property (it's text never change) and the last contains a regressive timer. The image below shows both items:
I want to eliminate the blank space that both texts have both top and bottom. I've tried several approaches...
android:includeFontPadding="false"
android:lineSpacingMultiplier="1"
android:lineSpacingExtra="0dp"
android:paddingTop="0dp"
android:paddingBottom="0dp"
android:layout_marginTop="0dp"
android:layout_marginBottom="0dp"
...but none of them removed the space above the text. How can I make both texts close to each other without any extra space?
PS: I've found this similar question, but no one answered it.
Full layout code:
<LinearLayout
android:id="#+id/boxTime"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="20dp" >
<TextView
android:id="#+id/textRemainingTime2"
android:layout_width="wrap_content"
android:layout_heigh="wrap_content"
android:layout_gravity="center"
android:gravity="center_horizontal"
android:textSize="70sp"
android:includeFontPadding="false"
android:lineSpacingMultiplier="1"
android:lineSpacingExtra="0dp"
android:paddingTop="0dp"
android:paddingBottom="0dp"
android:layout_marginTop="0dp"
android:layout_marginBottom="0dp"
android:text="#string/title" />
<TextView
android:id="#+id/textRemainingTime"
android:layout_width="wrap_content"
android:layout_heigh="wrap_content"
android:layout_gravity="center"
android:gravity="center_horizontal"
android:includeFontPadding="false"
android:lineSpacingMultiplier="1"
android:lineSpacingExtra="0dp"
android:paddingTop="0dp"
android:paddingBottom="0dp"
android:layout_marginTop="0dp"
android:layout_marginBottom="0dp"
android:textSize="107sp"
android:text="#string/timer" />
</LinearLayout>

Try using negative margins. It may take a bit of playing with the numbers to get it right, but I've done it before and it worked out well.
android:layout_marginTop="-5dp"

By default, a TextView includes some padding to leave space for accent characters. You can turn that off with:
android:includeFontPadding="false"
or
textView.setIncludeFontPadding(false)

Make baseline of the text equal to the bottom of the TextView.
public class BaselineTextView extends TextView {
public BaselineTextView(Context context, AttributeSet attrs) {
super(context, attrs);
}
#Override
protected void onDraw(Canvas canvas) {
int yOffset = getHeight() - getBaseline();
canvas.translate(0, yOffset);
super.onDraw(canvas);
}
}
NOTE: To avoid chopping off descenders call setClipChildren(false) on your TextView's parent ViewGroup (android:clipChildren="false" in XML).

If you set includeFontPadding to false it helps.
android:includeFontPadding="false"
but if you know you don't have any descenders because you set
android:textAllCaps="true"
or you know there are no characters which have descender, you can make a custom TextView and set the height to the baseline.
public class ExTextView extends TextView {
public ExTextView(Context context) {
this(context, null);
}
public ExTextView(Context context, #Nullable AttributeSet attrs) {
this(context, attrs, 0);
}
public ExTextView(Context context, #Nullable AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
}
#TargetApi(Build.VERSION_CODES.LOLLIPOP)
public ExTextView(Context context, #Nullable AttributeSet attrs, int defStyleAttr, int defStyleRes) {
super(context, attrs, defStyleAttr, defStyleRes);
}
#Override
protected void onDraw(Canvas canvas) {
setHeight(getBaseline()); // <--- Shrink size to baseline
super.onDraw(canvas);
}
}
The source code is included in my UiComponents test app.
https://github.com/landenlabs/UiComponents

Just use below, nothing else required.
android:includeFontPadding="false"
if you want some variations in line gap then use :
android:lineSpacingExtra

negative margins will do the trick

Since my requirement is override the existing textView get from findViewById(getResources().getIdentifier("xxx", "id", "android"));, so I can't simply try onDraw() of other answer.
But I just figure out the correct steps to fixed my problem, here is the final result from Layout Inspector:
Since what I wanted is merely remove the top spaces, so I don't have to choose other font to remove bottom spaces.
Here is the critical code to fixed it:
Typeface mfont = Typeface.createFromAsset(getResources().getAssets(), "fonts/myCustomFont.otf");
myTextView.setTypeface(mfont);
myTextView.setPadding(0, 0, 0, 0);
myTextView.setIncludeFontPadding(false);
The first key is set custom font "fonts/myCustomFont.otf" which has the space on bottom but not on the top, you can easily figure out this by open otf file and click any font in android Studio:
As you can see, the cursor on the bottom has extra spacing but not on the top, so it fixed my problem.
The second key is you can't simply skip any of the code, otherwise it might not works. That's the reason you can found some people comment that an answer is working and some other people comment that it's not working.
Let's illustrated what will happen if I remove one of them.
Without setTypeface(mfont);:
Without setPadding(0, 0, 0, 0);:
Without setIncludeFontPadding(false);:
Without 3 of them (i.e. the original):

Negative Margins would do the work. You can set it by two methods -
1) by xml - set the android:Layout_marginTop="-10dp" field negative
2) by java (Programmatically) - set the topMargin field of LayoutParams to negative.

you should change the height of TextView and maybe change android:gravity="bottom"
height is between textsize and size of textView with Wrapcontent.
public class MyTextViewBounder extends TextView {
public MyTextViewBounder(Context context) {
super(context);
}
public MyTextViewBounder(Context context, AttributeSet attrs) {
super(context, attrs);
}
public MyTextViewBounder(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
}
#Override
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
//test kích thước thực tế với kích thước của Textview bao quanh text của nó như thế nào
int width, height;
Paint iPaint;
Rect iRect = new Rect();
iPaint = new Paint();
iPaint.setTextSize(13);
iPaint.setTextAlign(Paint.Align.CENTER);
//call below code outsite
//this.setText("Hung");
//this.setTextSize(TypedValue.COMPLEX_UNIT_PX,13);
//this..setIncludeFontPadding(false); //height from 18px down to 15px
iPaint.getTextBounds("Hung",0,4,iRect); //width = 34px, height = 12px
width = this.getWidth(); //= 30px
height = this.getHeight(); //= 18px
width = this.getMeasuredWidth(); //=30px
height = this.getMeasuredHeight(); //= 18px
width = iRect.width(); //34px
height = iRect.height(); //12 px
}
}

How to have Image and Text Center within a Button

I want to display TEXT and Icon on a Button.
+----------------------------+
| Icon TEXT |
+----------------------------+
I tried with
<Button
android:id="#+id/Button01"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:paddingLeft="40dip"
android:text="TEXT"
android:drawableLeft="#drawable/Icon" />
But Text and Icon is not in center.
My Text size varies, according to text size Icon and Text should get adjusted to center.
How should i do it?

You can fake it by making a more complex layout, but I'm not sure whether it's worth it. Here's something I hacked together:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<Button
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:layout_alignTop="#+id/foreground"
android:layout_alignBottom="#id/foreground"
android:layout_alignRight="#id/foreground"
android:layout_alignLeft="#id/foreground"
android:onClick="clickedMe" />
<RelativeLayout
android:id="#id/foreground"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TextView
android:id="#+id/button_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:text="#string/hello" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_toLeftOf="#id/button_text"
android:paddingTop="10dip"
android:paddingBottom="10dip"
android:src="#drawable/icon" />
</RelativeLayout>
</RelativeLayout>
There might be a more concise way to do it. I tend to struggle getting RelativeLayout to do what I want sometimes. Note that you need to pay attention to the z-order (Button needs to appear first in the top level RelativeLayout) and you might need to adjust padding to get it to look the way you want.

Similar to some other approaches, I think a good solution is to extend Button and add the missing functionality by overriding its onLayout method:
public class CenteredIconButton extends Button {
private static final int LEFT = 0, TOP = 1, RIGHT = 2, BOTTOM = 3;
// Pre-allocate objects for layout measuring
private Rect textBounds = new Rect();
private Rect drawableBounds = new Rect();
public CenteredIconButton(Context context) {
this(context, null);
}
public CenteredIconButton(Context context, AttributeSet attrs) {
this(context, attrs, android.R.attr.buttonStyle);
}
public CenteredIconButton(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
#Override
protected void onLayout(boolean changed, int left, int top, int right, int bottom) {
super.onLayout(changed, left, top, right, bottom);
if (!changed) return;
final CharSequence text = getText();
if (!TextUtils.isEmpty(text)) {
TextPaint textPaint = getPaint();
textPaint.getTextBounds(text.toString(), 0, text.length(), textBounds);
} else {
textBounds.setEmpty();
}
final int width = getWidth() - (getPaddingLeft() + getPaddingRight());
final Drawable[] drawables = getCompoundDrawables();
if (drawables[LEFT] != null) {
drawables[LEFT].copyBounds(drawableBounds);
int leftOffset =
(width - (textBounds.width() + drawableBounds.width()) + getRightPaddingOffset()) / 2 - getCompoundDrawablePadding();
drawableBounds.offset(leftOffset, 0);
drawables[LEFT].setBounds(drawableBounds);
}
if (drawables[RIGHT] != null) {
drawables[RIGHT].copyBounds(drawableBounds);
int rightOffset =
((textBounds.width() + drawableBounds.width()) - width + getLeftPaddingOffset()) / 2 + getCompoundDrawablePadding();
drawableBounds.offset(rightOffset, 0);
drawables[RIGHT].setBounds(drawableBounds);
}
}
}
The sample only works for left and right drawables, but could be extended to adjust top and bottom drawables too.

How about this one?
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/lovely_color"
android:clickable="true"
android:onClick="clickHandler">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="no?"
android:textColor="#color/white"
android:layout_centerHorizontal="true"
android:drawableLeft="#drawable/lovely_icon"
android:drawablePadding="10dp"
android:padding="10dp"
android:gravity="center"
android:textSize="21sp"/>
</RelativeLayout>

This should work
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal">
<TextView
android:id="#+id/button_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:text="hello" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:paddingBottom="10dip"
/>
</LinearLayout>

How about using a SpannableString as the text with an ImageSpan?
Button myButton = ...
SpannableString ss = new SpannableString(" " + getString(R.string.my_button_text));
Drawable d = getResources().getDrawable(R.drawable.myIcon);
d.setBounds(0, 0, d.getIntrinsicWidth(), d.getIntrinsicHeight());
ImageSpan span = new ImageSpan(d, DynamicDrawableSpan.ALIGN_BOTTOM);
ss.setSpan(span, 0, 1, Spanned.SPAN_INCLUSIVE_EXCLUSIVE);
myButton.setText(ss);

You can just set a padding depending on button size and image size:
Button button1 = null;
//initialize button….
ViewGroup.LayoutParams params = button1.getLayoutParams();
int btn1Width = ((int) (0.33 * (double)ecranWidth));
params.width = btn1Width;
button1.setLayoutParams(params);
button1.setPadding((btn1Width/2-9), 0, 0, 0);
//where (btn1Width/2-9) = size of button divided on 2 minux half size of icon…

The easy way (albeit not perfect) is to set the paddingRight to the same width as your icon.

<com.google.android.material.button.MaterialButton
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/your_text"
app:icon="#drawable/ic_example"
app:iconGravity="textStart"/>

This is what I did... It can be improved. The text is centered and the icon is to the left. So they both aren't centered as a group.
public class CustomButton extends Button
{
Rect r = new Rect();
private Drawable buttonIcon = null;
private int textImageSeparation = 10;
public CustomButton(Context context, AttributeSet attrs, int defStyle)

{
super.onDraw(canvas);
Drawable icon = getButtonIcon();
if(icon != null)
{
int drawableHeight = icon.getIntrinsicHeight();
int drawableWidth = icon.getIntrinsicWidth();
if(icon instanceof BitmapDrawable)
{
Bitmap bitmap = ((BitmapDrawable)icon).getBitmap();
drawableWidth = (int) AndroidScreenUtils.dipToPixels(bitmap.getWidth());
drawableHeight = (int) AndroidScreenUtils.dipToPixels(bitmap.getHeight());
}
else
{
drawableWidth = (int) AndroidScreenUtils.dipToPixels(icon.getIntrinsicWidth());
drawableHeight = (int) AndroidScreenUtils.dipToPixels(icon.getIntrinsicHeight());
}
float textWidth = getLayout().getPaint().measureText(getText().toString());
float left = ((getWidth() - textWidth) / 2) - getTextImageSeparation() - drawableWidth;
int height = getHeight();
int top = (height - drawableHeight) /2;
int right = (int) (left + drawableWidth);
int bottom = top + drawableHeight;
r.set((int) left, top, right, bottom);
icon.setBounds(r);
icon.draw(canvas);
}
}
private Drawable getButtonIcon()
{
return buttonIcon;
}
public void setButtonIcon(Drawable buttonIcon)
{
this.buttonIcon = buttonIcon;
}
private int getTextImageSeparation()
{
return textImageSeparation;
}
public void setTextImageSeparation(int dips)
{
this.textImageSeparation = (int) AndroidScreenUtils.dipToPixels(dips);
}
}

I made a custom component to solve this problem.
Component class:
class CustomImageButton #JvmOverloads constructor(
context: Context,
attrs: AttributeSet? = null,
defStyleAttr: Int = 0,
defStyleRes: Int = 0
) : RelativeLayout(context, attrs, defStyleAttr, defStyleRes) {
init {
inflate(context, R.layout.custom_image_button, this)
// Load the styled attributes and set their properties
val typedArray = context.obtainStyledAttributes(
attrs,
R.styleable.CustomImageButton, defStyleAttr, 0
)
val src = typedArray?.getDrawable(R.styleable.CustomImageButton_cib_src)
val text = typedArray?.getText(R.styleable.CustomImageButton_cib_text)
val contentDescription = typedArray?.getText(R.styleable.CustomImageButton_cib_contentDescription)
ivIcon.setImageDrawable(src)
tvText.text = text
ivIcon.contentDescription = contentDescription
typedArray?.recycle()
}
}
Component XML:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"

app:layout_constraintStart_toStartOf="parent"
app:layout_constraintBottom_toBottomOf="parent"
android:layout_width="fill_parent"
android:layout_height="#dimen/button_height">
<Button
android:id="#+id/bClick"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:layout_alignTop="#+id/foreground"
android:layout_alignBottom="#id/foreground"
android:layout_alignEnd="#id/foreground"
android:layout_alignStart="#id/foreground"/>
<RelativeLayout

toos:ignore="RelativeOverlap"/>
<ImageView

android:layout_width="wrap_content"

android:paddingTop="1dip"
android:paddingBottom="1dip"
android:src="#mipmap/some_image_to_test"
toos:ignore="ContentDescription"/>
</RelativeLayout>
</RelativeLayout>
The resources attributes, attrs.xml:
<declare-styleable name="CustomImageButton">
<attr name="cib_src" format="reference"/>
<attr name="cib_text" format="string"/>
<attr name="cib_contentDescription" format="string"/>
</declare-styleable>
Component use example:
<app.package.components.CustomImageButton
android:id="#+id/cibMyImageButton"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintBottom_toBottomOf="parent"
android:layout_height="wrap_content"
android:layout_width="match_parent"
app:cib_src="#mipmap/my_image_to_put_in_the_button"
app:cib_text="Some text to show in the button"
app:cib_contentDescription="icon description"/>

This is a hack, but worked for me with a negative margin:
<Button
android:id="#+id/some_id"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:drawableStart="#drawable/some_drawable"
android:drawablePadding="-118dp"
android:paddingEnd="28dp"
android:text="#string/some_string" />
A better way would probably be doing this in a custom view

android:layout_gravity="center_vertical|center_horizontal|center" >
