How to add a View above the display Android

I want to create a translate animation which will pop up a View from the top of the screen. Now I need to put my view above the screen , so that it will be invisible . The root of all Views is a vertical LinearLayout . This is how I inflate the RelativeLayout (which is going to be animated) into my LinearLayout.
final LinearLayout root = (LinearLayout) findViewById (R.id.mainLayout);
final RelativeLayout container = (RelativeLayout)
LayoutInflater.from(getBaseContext()).
inflate(R.layout.animated_layout ,
root , false );
root.addView(container);
and this is the Relativelayout xml .
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="70dp"
android:background="#drawable/list_item_back1" >
<TextView
android:textSize="25sp"
android:layout_width = "match_parent"
android:layout_height="match_parent"/>
</RelativeLayout>

Ass you said, become your view invisible. Then, create an XML translate animation:
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="#android:anim/linear_interpolator">
<translate
android:fromYDelta="100%"
android:toYDelta="0%"
android:duration="1000" />
</set>
In your java code do something like this:
Animation translateAnimation = AnimationUtils.loadAnimation(getApplicationContext(), R.anim.translate_animation);
translateAnimation.setAnimationListener(new Animation.AnimationListener() {
#Override
public void onAnimationStart(Animation animation) {
yourAnimatedView.setvisibility(View.VISIBLE);
}
#Override
public void onAnimationEnd(Animation animation) {
}
#Override
public void onAnimationRepeat(Animation animation) {
}
yourAnimatedView.startAnimation(translateAnimation);
});

List navigation (spinner) on the right side

I have tried so many tutorials, but I could not find article that would tell me how to create spinner in action bar (sherlock version), but on the right side.
Is there a way to do it? Do I need to create additional views and adapters? I just want to know easy way to create that spinner on the right side, nothing else, just it.

You'll need to create a custom layout for the view containing the spinner. Inflate and place it on the action bar and you're good to go.
Here you have some sample code for this(this is what you do inside your activity to initialize and place your layout on the action bar):
LayoutInflater inflater = (LayoutInflater) getSupportActionBar().getThemedContext().getSystemService(LAYOUT_INFLATER_SERVICE);
final View spinnerView = inflater.inflate(R.layout.layout_spinner, null);
Spinner spinner = (Spinner) spinnerView.findViewById(R.id.my_spinner);
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this, R.array.spinner_items_array, R.layout.spinner_item);
adapter.setDropDownViewResource(R.layout.spinner_dropdown_item);
spinner.setAdapter(adapter);
spinner.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
// Do whatever you want with your selected item. You can get it as: parent.getItemAtPosition(position);
}
#Override
public void onNothingSelected(AdapterView<?> parent) {}
});
getSupportActionBar().setIcon(getResources().getDrawable(R.drawable.ic_actionbar_logo));//set your actionbar logo
getSupportActionBar().setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM | ActionBar.DISPLAY_SHOW_HOME | ActionBar.DISPLAY_HOME_AS_UP | ActionBar.DISPLAY_SHOW_TITLE );
LayoutParams layoutParams = new ActionBar.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.MATCH_PARENT);
layoutParams.gravity = Gravity.RIGHT; // set your layout's gravity to 'right'
getSupportActionBar().setCustomView(spinnerView, layoutParams); //place your layout on the actionbar
Your layout should look something like this (layout_spinner.xml):
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<Spinner
style="#style/Widget.Sherlock.Light.Spinner.DropDown.ActionBar"
android:id="#+id/my_spinner"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="right" />
</LinearLayout>
Your array stored in a res folder (spinner_items_array):
<string-array name="spinner_items_array">
<item>Item1</item>
<item>Item2</item>
</string-array>
The spinner custom item (spinner_item.xml):
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/cab_spinner_item"
style="?android:attr/spinnerItemStyle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:ellipsize="marquee"
android:singleLine="true"
android:textAlignment="inherit"
android:textColor="#android:color/white" /> <!-- Set whatever color you want for the text -->
And finally the drop-down list item (spinner_dropdown_item.xml):
<?xml version="1.0" encoding="utf-8"?>
<CheckedTextView xmlns:android="http://schemas.android.com/apk/res/android"
style="?android:attr/spinnerDropDownItemStyle"
android:layout_width="match_parent"
android:layout_height="48dp"
android:ellipsize="marquee"
android:singleLine="true"
android:textAlignment="inherit"
android:textColor="#android:color/white" />
I hope this answer will help you!!
Good luck!

How to Increase the size of Image View in Android

I am working on a project that requires me to implement two horizontal scroll views with an image view in between them. I would like to extend the size of the image view to fill up the gap in between the scroll view. I went through the sample code, but it doesn't seem to mention anywhere in the size of the image view. I've enclosed the code below after the Image describing my problem.
public class Gallery2DemoActivity extends Activity {
private Gallery gallery,gallery1;
private ImageView imgView;
private Integer[] Imgid = {
R.drawable.a_1, R.drawable.a_2, R.drawable.a_3, R.drawable.a_4, R.drawable.a_5, R.drawable.a_6, R.drawable.a_7
};
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
gallery = (Gallery) findViewById(R.id.examplegallery);
gallery.setAdapter(new AddImgAdp(this));
gallery1 = (Gallery)findViewById(R.id.examplegallery1);
gallery1.setAdapter(new AddImgAdp(this));
imgView = (ImageView)findViewById(R.id.ImageView01);
imgView.setImageResource(Imgid[0]);
gallery.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView parent, View v, int position, long id) {
imgView.setImageResource(Imgid[position]);
}
});
}
public class AddImgAdp extends BaseAdapter {
int GalItemBg;
private Context cont;
public AddImgAdp(Context c) {
cont = c;
TypedArray typArray = obtainStyledAttributes(R.styleable.GalleryTheme);
GalItemBg = typArray.getResourceId(R.styleable.GalleryTheme_android_galleryItemBackground, 0);
typArray.recycle();
}
public int getCount() {
return Imgid.length;
}
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
ImageView imgView = new ImageView(cont);
imgView.setImageResource(Imgid[position]);
imgView.setLayoutParams(new Gallery.LayoutParams(110, 100));
imgView.setScaleType(ImageView.ScaleType.FIT_XY);
imgView.setBackgroundResource(GalItemBg);
return imgView;
}
}
This is my XML main file.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/LinearLayout01"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<Gallery
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/examplegallery"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<ImageView
android:id="#+id/ImageView01"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1"/>
<Gallery
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/examplegallery1"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
</LinearLayout>
Below is my Attributes file:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<declare-styleable name="GalleryTheme">
<attr name="android:galleryItemBackground" />
</declare-styleable>
</resources>

Vinner,
The issue here is really two issues:
The size of the ImageView is based on the parent, which means that it shares its width and height.
The Image is resized to match the most limiting dimension (width).
The easiest way to handle this is to set the ScaleType of the ImageView. There are a number of Scaling Types, but the one you probably want is Center Crop. In code, this is done by view_name.setScaleType(ImageView.ScaleType.CENTER_CROP). You may also do this in XML for your ImageView with the attribute android:scaleType="centerCrop". Mind you, this will resize your Image and maintain your aspect ratio, but it will cut off the sides.
Just add the above attribute to your ImageView in your XML, (probably under your layout_weight), and it should do what you want.
Hope this helps,
FuzzicalLogic

will you try below code... ?
?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/LinearLayout01"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<Gallery
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/examplegallery"
android:layout_width="fill_parent"
android:layout_height="wrap_content" android:layout_weight="1" />
<ImageView
android:id="#+id/ImageView01"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:src="#drawable/ic_launcher"
android:layout_weight="1"/>
<Gallery
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/examplegallery1"
android:layout_width="fill_parent"
android:layout_height="wrap_content" android:layout_weight="1"/>
</LinearLayout>
and if it do not work, try setting your gallery height to some dp, it will work.. Thanks

The size of the ImageView is based on the parent, which means that it shares its width and height. Also, the Image is resized to match the most limiting dimension (width).

It looks like in the AddImgAdp class, you set the ImageView's height and width to specific pixel sizes.
imgView.setLayoutParams(new Gallery.LayoutParams(110, 100)); //width = "110px", height="100px"
I personally would put the layout as a RelativeLayout, align the first gallery with the top, the second gallery with the bottom, nd have the ImageView set to align above the second gallery. Then make the image:
imgView.setLayoutParams( new Gallery.LayoutParams(
Gallery.LayoutParams.FILL_PARENT,
Gallery.LayoutParams.FILL_PARENT) );
If you set the ImageView to fill_parent with a LinearLayout, it will fill to the bottom of the screen and the second gallery will be off the screen.
Also know that by filling in all the space you will most likely distort the picture. Consider all of your resizing options: http://developer.android.com/reference/android/widget/ImageView.ScaleType.html

Scroll a RelativeLayout when it contains custom Views

I'm trying to make scrollable RelativeLayout, that contains some custom Views. This is the plan of cinema hall, i have x, y coordinates of places and it's width and height (that are just rectangales, actually). I just put it into this RelativeLayout:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:padding="10px">
<ScrollView
android:layout_height="wrap_content"
android:layout_width="fill_parent">
<RelativeLayout android:id="#+id/scrollable_places"
android:layout_height="wrap_content"
android:layout_width="wrap_content">
</RelativeLayout>
</ScrollView>
I put it like this:
RelativeLayout layout = (RelativeLayout) context.findViewById(R.id.scrollable_places);
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(place.getWidth(),
place.getHeight());
params.leftMargin = place.getX();
params.topMargin = place.getY();
layout.addView(new Seat(context, place), params);
Seat class looks like this:
public class Seat extends View {
private Place place;
private boolean isRed = false;
public Seat(Context context, Place place) {
super(context);
this.place = place;
setOnClickListener(new OnSeatClickListener());
}
#Override
protected void onDraw(Canvas canvas) {
if (!isRed)
canvas.drawColor(Color.GREEN);
else
canvas.drawColor(Color.RED);
}
protected void setRed() {
isRed = true;
}
private class OnSeatClickListener implements OnClickListener {
#Override
public void onClick(View view) {
((Seat) view).setRed();
view.invalidate();
}
}
}
Views are drawing perfectly. But I have ann array of views, and when some of them go out of the screen, scrollView didn't work, there is no scroll on the screen. Have you any ideas how can I make this layout scroll?

You should try following xml file. It will work on all the devices.
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:fillViewport="true"
android:padding="10px"
android:layout_height="fill_parent"
android:layout_width="fill_parent">
<RelativeLayout android:id="#+id/scrollable_places"
android:layout_height="wrap_content"
android:layout_width="wrap_content">
</RelativeLayout>
</ScrollView>
Thanks.

In scroll view you have written android:layout_height="wrap_content" instead of using wrap_content five specific height size eg android:layout_height="100dip"
Thanks

Fade effect between layouts

As by object, I would reproduce fade effect between two layout.
Now I've this situation:
LinearLayout l;
LinearLayout l2;
To switch between them I've used
l.setVisibility(View.GONE);
l2.setVisibility(View.VISIBLE);
I want add fade effect between this transiction, how I can do it?

Here is a working solution to cross fade between 2 layouts:
public class CrossFadeActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.crossfade);
final View l1 = findViewById(R.id.l1);
final View l2 = findViewById(R.id.l2);
final Animation fadeOut = AnimationUtils.loadAnimation(CrossFadeActivity.this, R.anim.fade_out);
final Animation fadeIn = AnimationUtils.loadAnimation(CrossFadeActivity.this, R.anim.fade_in);
findViewById(R.id.button1).setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
fadeOut.setAnimationListener(new AnimationListener() {
#Override
public void onAnimationStart(Animation animation) {
}
#Override
public void onAnimationRepeat(Animation animation) {
}
#Override
public void onAnimationEnd(Animation animation) {
l1.setVisibility(View.GONE);
}
});
l1.startAnimation(fadeOut);
l2.setVisibility(View.VISIBLE);
l2.startAnimation(fadeIn);
}
});
findViewById(R.id.button2).setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
fadeOut.setAnimationListener(new AnimationListener() {
#Override
public void onAnimationStart(Animation animation) {
}
#Override
public void onAnimationRepeat(Animation animation) {
}
#Override
public void onAnimationEnd(Animation animation) {
l2.setVisibility(View.GONE);
}
});
l2.startAnimation(fadeOut);
l1.setVisibility(View.VISIBLE);
l1.startAnimation(fadeIn);
}
});
}
}
crossfade.xml:
<?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="fill_parent"
android:orientation="vertical" >
<LinearLayout
android:id="#+id/l1"
android:layout_width="fill_parent"
android:layout_height="300dip"
android:orientation="vertical"
android:background="#drawable/someimage"
>
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button" />
</LinearLayout>
<RelativeLayout
android:id="#+id/l2"
android:layout_width="fill_parent"
android:layout_height="300dip"
android:orientation="vertical"
android:background="#drawable/someimage2"
android:visibility="gone"
>
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button"
android:layout_centerInParent="true"
/>
</RelativeLayout>
</RelativeLayout>
Where l1 and l2 are 2 random example layouts. The trick is to put them in XML such that they overlap each other (e.g. in a RelativeLayout) with visible / gone, add listeners to the animations to toggle the visibility on finish, and set the view which has to fade in to visible before the animation starts, otherwise the animation will not be visible.
I put the buttons with the listeners to toggle the animation in the layouts itself, because I need to implement it that way but the click listener can be of course somewhere else (if it's only one it should be used in combination with some flag or check to know how to toggle).
These are the animation files. They have to be stored in folder res/anim:
fade_in.xml
<?xml version="1.0" encoding="UTF-8"?>
<alpha xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="1000"
android:fillAfter="true"
android:fromAlpha="0.0"
android:toAlpha="1.0" />
fade_out.xml
<?xml version="1.0" encoding="UTF-8"?>
<alpha xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="1000"
android:fillAfter="true"
android:fromAlpha="1.0"
android:toAlpha="0" />
UPDATE:
Instead of using R.anim.fade_in, you can use the default fade_in from Android API (android.R.fade_in):
final Animation fadeIn = AnimationUtils.loadAnimation(CrossFadeActivity.this, android.R.anim.fade_in);
Using android.R.anim.fade_in, you will not need to create the file res/anim/fade_in.xml.
Android has a package with some useful animations on android.R.anim: http://developer.android.com/reference/android/R.anim.html

Using R.anim.fade_out & .R.anim.fade_in you can create an animation which does this. I don't know much about this myself but heres a tutorial regarding animations in android: Animation Tutorial
P.S. This tutorial is not mine thus credit does not go out to me.
Edit:
AnimationSet set = new AnimationSet(true);
Animation animation = new AlphaAnimation(0.0f, 1.0f);
animation.setDuration(50);
set.addAnimation(animation);
animation = new TranslateAnimation(
Animation.RELATIVE_TO_SELF, 0.0f,Animation.RELATIVE_TO_SELF, 0.0f,
Animation.RELATIVE_TO_SELF, -1.0f,Animation.RELATIVE_TO_SELF, 0.0f
);
animation.setDuration(100);
set.addAnimation(animation);
LayoutAnimationController controller = new LayoutAnimationController(set, 0.5f);
l.setLayoutAnimation(controller);
Fade out Animation
public static Animation runFadeOutAnimationOn(Activity ctx, View target) {
Animation animation = AnimationUtils.loadAnimation(ctx,android.R.anim.fade_out);
target.startAnimation(animation);
return animation;
}
I'm guessing you can try something like this, I copy pasted the animation from the tutorial I don't know what it does exactly as I have no experience with Android development. Another example could be Example 2

Since android 3.0 you can use
android:animateLayoutChanges="true"
in a layout in xml and any changes to this specific layouts content at run time will be animated. For example, in your case, you will need to set this attribute for the parent for the parent layout of l and l2 e.g
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
tools:context="me.kalem.android.RegistrationActivity"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:animateLayoutChanges="true"
android:padding="20dp">
<LinearLayout
android:id="#+id/l1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:visibility="visible">
........
</LinearLayout>
<LinearLayout
android:id="#+id/l2"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:visibility="gone">
........
</LinearLayout>
</LinearLayout>
Now hiding l1 and showing l2 at runtime will be animated.
