Animate a layouts alpha - android

I have a layout that i am trying to animate. It initially has its visibility set to GONE with alpha 0.
I then use the following to animate it:
final LinearLayout layout = (LinearLayout) findViewById(R.id.main_info);
layout.setVisibility(View.VISIBLE);
layout.bringToFront();
final AlphaAnimation animation = new AlphaAnimation(0F, 0.8F);
animation.setDuration(time);
animation.setFillAfter(true);
layout.startAnimation(animation);
But nothing happends. I have used the same code with a progressBar and i get the result i want. Why isnt it working for my layout?
I am animating it to come in front of another layout (if it isnt already) to act as an information screen hence the bringToFront(). I would like to add that i have since deleted the bringToFront() and there is no change. So the problem is nothing to do with that.

Which in general is an imageview that takes the whole screen and acts as a background image, the above it i have a linearlayout (MainLinearLayout) that hold vertically a textview, an imagebutton (AngryImageButton) and another linearlayout (BottomLinearLayout) that is just display a small image (like the logo) horizontally centered.
I want to be able to change programatically the size of the AngryImageButton and the BottomLinearLayout to be displayed in the bottom of the screen and to be always visible. I mean to be on top of the other views.
Right now the BottomLinearLayout appears in the center and below the MainLinearLayout and if i make the AngryImageButton very large, it pushes below the BottomLinearLayout until its not visible in the screen at all, i don't want that. I want it to be at the bottom, and always visible.
How i can accomplish that? Also i want the layout to work in both orientations
To bring View to front, you can use
myView.bringToFront()
or You can make use of ViewCompat and set its translation Z like below.
ViewCompat.setTranslationZ(view, 1)
here's the doc for bringToFront() bringToFront()

View doesn't reappear after setVisibility(View.GONE)

I have a LinearLayout which I'm trying to make VISIBLE, then GONE, then VISIBLE again. However after making it GONE, it doesn't become visible again. As a note, it works fine if I make it INVISIBLE: it appears and disappears with no problem.
These are my files:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">

android:text="#string/loading"
android:textColor="#000"
android:padding="#dimen/activity_padding"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
</LinearLayout>
This is the method I'm using to show/hide:
private void hideOrShowLoading(final boolean show) {
final ViewGroup spinnerWrapper = (ViewGroup)ll.findViewById(R.id.spinner_wrapper);
final View spinner = ll.findViewById(R.id.spinner);
if (show) {
spinnerWrapper.setVisibility(View.VISIBLE); // Not working after being set to GONE previously
final Animation rotation = AnimationUtils.loadAnimation(getContext(), R.anim.rotate);
rotation.setFillAfter(true);
spinner.startAnimation(rotation);
} else {
spinnerWrapper.setVisibility(View.GONE);
spinner.clearAnimation();
}
}
Any tips? Could it have something to do with the ListView above it having a height of 0 and a weight of 1?
Thanks
Update
I also tried the following after the if (show) block, with no luck:
listview.invalidate();
spinnerWrapper.invalidate();
ll.invalidate();
ll.requestLayout();
ll is the LinearLayout that contains both.
While I believe this is caused by the layout_weight=1 property, I wasn't able to properly fix this.
The following hack did work. Basically, I'm surrounding the spinnerWrapper in another linear layout which is always visible.
<?xml version="1.0" encoding="utf-8"?>

Linear Layout behind ImageView in Relative Layout

Let me explain i have a xml like this
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ImageView
android:id="#+id/imgCircle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/img_circle" />
<LinearLayout
android:id="#+id/llFirstScreen"
android:layout_alignTop="#id/imgCircle"
android:layout_alignBottom="#id/imgCircle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_toRightOf="#id/imgCircle"
android:layout_toEndOf="#id/imgCircle"
android:background="#drawable/layout_view_round_corner"
android:orientation="vertical">
<TextView
android:id="#+id/mapCurrentLocation"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:text="TextView1"
android:textColor="#color/lblTextColor"
android:textSize="#dimen/lblTextLarge"
android:textStyle="normal" >
</TextView>
<TextView
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:text="TextView2"
android:textColor="#color/lblHintColor2"
android:textSize="#dimen/lblTextMedium"
android:textStyle="normal" >
</TextView>
</LinearLayout>
</RelativeLayout>
And this gives me Image and TextViews next to it
But i want to accomplish something like this
that TextView Background is extended (padding maybe) at the half of the Rounded Image (behind it) so that it looks like its "part" of the image. Or I was thinking of Making a view with background white that goes behind TextView so that it looks that way. But wanted to ask here maybe if there is a better way to do this.
I hope i was clear in explaining this (That is why I added pictures).
I have tried to use demo with your xml file and you can check below code. I had to give static height and width of the ImageView to achieve result.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<LinearLayout
android:id="#+id/llFirstScreen"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignBottom="#id/imgCarCircle"
android:layout_alignTop="#id/imgCarCircle"
android:layout_marginLeft="30dp"
android:background="#color/colorAccent"
android:orientation="vertical"
android:paddingLeft="40dp">
<TextView
android:id="#+id/mapCurrentLocation"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:text="text1"
android:textStyle="normal"></TextView>
<TextView
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:text="text2"
android:textStyle="normal"></TextView>
</LinearLayout>
<ImageView
android:id="#+id/imgCarCircle"
android:layout_width="60dp"
android:layout_height="60dp"
android:src="#mipmap/ic_launcher_round" />
</RelativeLayout>
try these:
first solution: change this
<LinearLayout
android:id="#+id/llFirstScreen"
android:layout_alignTop="#id/imgCircle"
android:layout_alignBottom="#id/imgCircle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_toRightOf="#id/imgCircle"
android:layout_toEndOf="#id/imgCircle"
android:background="#drawable/layout_view_round_corner"
android:orientation="vertical">
to this:
<LinearLayout
android:id="#+id/llFirstScreen"
android:layout_alignTop="#id/imgCircle"
android:layout_alignBottom="#id/imgCircle"
android:layout_width="match_parent"
android:layout_marginLeft="20dp" // or just figure your image width and set this programatically
android:layout_height="wrap_content"
android:background="#drawable/layout_view_round_corner"
android:orientation="vertical">
second solution: it to use AbsoluteLayout which is a bit hard to handle.

Android - ImageView overlay another ImageView

I would like to make an ImageView overlay another ImageView like this; only half of the circle green is overlaying the image:
I have tried using RelativeLayout and put both ImageView inside. Then I overlay the circle over the image by using android:layout_alignBottom. It did overlay the but I have no idea how to set the offset so that only half of the circle is overlaying the base image.
EDIT:
Sorry, here is my layout xml code
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_marginBottom="32sp" >
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:src="#drawable/ic_person_black"
android:adjustViewBounds="true"
android:id="#+id/image_view_product" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="#id/image_view_product"
android:layout_centerHorizontal="true"
android:background="#drawable/image_view_circle"
android:src="#drawable/ic_circle" />
</RelativeLayout>
I get lots of upvote for this answer.So i try to improve that answer. May be this is the better way to do that compare to other two, because this solution doesn't required to fix the layout or divide screen in equal part so may be this is better to do that.

Alternate way Try this
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
// this is your first layout to put the big image
// use src or backgroud image as per requirement
<LinearLayout
android:background="#color/red_error"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1">
</LinearLayout>
// this is your bottom layout
<LinearLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1">
</LinearLayout>
</LinearLayout>
// This is the imageview which overlay the first LinearLayout
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/success"
android:adjustViewBounds="true"
android:layout_gravity="center"/>
</FrameLayout>
its look like this
found one more solution for that (Edit)
if your big image size is fixed height you can try this
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<RelativeLayout
android:id="#+id/layoutTop"
android:background="#color/red_error"
android:layout_width="match_parent"
android:layout_height="200dp" >
</RelativeLayout>
<RelativeLayout
android:id="#+id/layoutBottom"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_alignParentBottom="true"
android:layout_below="#id/layoutTop" >
</RelativeLayout>
<ImageView
android:id="#+id/overlapImage"
android:layout_width="wrap_content"
android:layout_height="40dp"
android:layout_above="#id/layoutBottom"
android:layout_centerHorizontal="true"
android:layout_marginBottom="-20dp"
android:adjustViewBounds="true"
android:src="#drawable/testimage" />
</RelativeLayout>
Refernce :- Android: Placing ImageView on overlap between layouts
Hope this will help.Good Luck
Try out this way:
Just change layout_width and layout_height according to your need.
<?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:orientation="vertical" >
<View
android:id="#+id/viewOne"
android:layout_width="match_parent"
android:layout_height="200dp"
android:background="#126989" />
<View
android:id="#+id/viewTwo"
android:layout_width="match_parent"
android:layout_height="70dp"
android:layout_below="#+id/viewOne"
android:background="#547866" />
<View
android:layout_width="70dp"
android:layout_height="70dp"
android:layout_alignBottom="#+id/viewTwo"
android:layout_centerHorizontal="true"
android:background="#ff7800"
android:layout_marginBottom="35dp" />
</RelativeLayout>
It will look like this:
I would recommend Constraintlayout as it gives excellent control over the positioning of individual view items. Sample based on your example below
<android.support.constraint.ConstraintLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:id="#+id/parentLayout">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ic_person_black"
android:adjustViewBounds="true"
android:id="#+id/image_view_product"/>
<View
android:layout_width="50dp"
android:layout_height="50dp"
app:layout_constraintTop_toBottomOf="#+id/image_view_product"/>
<ImageView
android:layout_width="100dp"
android:layout_height="100dp"
android:layout_alignBottom="#id/image_view_product"
android:layout_centerHorizontal="true"
android:background="#drawable/circle"
android:src="#drawable/ic_add_circle_green_24dp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"/>
</android.support.constraint.ConstraintLayout>
Use layout_marginTop = -20dp ( Half of your image size ). It will go up.
android:layout_marginTop="-20dp"
put both the image in Relative layout
first define the image you want to put behind the green circle
than define the green circle as
android:layout_alignBottom="#+id/Image1"
Than adjust the position by giving margin to the green circle image.
I recommend you to use a framelayout with these two images.
with the refresh imageview at the bottom and the table fan at the top.
Note : As the framelayout behaves like a stack, the item at the bottom will appear at the top.
And do the set the gravity of the refresh icon to be bottom|center to make it look this way.
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ImageView
android:src="#drawable/ic_fan"
android:scaleType="centerCrop"
android:layout_height="wrap_content"
android:layout_width="match_parent"/>
<ImageView
android:src="#drawable/ic_refresh"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:gravity="center|bottom"/>
</FrameLayout>
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_marginBottom="32sp" >
<ImageView
android:id="#+id/ivBackground"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:src="#drawable/ic_person_black"
android:adjustViewBounds="true"
android:id="#+id/image_view_product" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="40dp"
android:layout_marginTop="-20dp"
android:layout_below="#+id/ivBackground"
android:layout_centerHorizontal="true"
android:background="#drawable/image_view_circle"
android:src="#drawable/ic_circle" />
I think this should help you i have edited your code and made changes as below
- I change circle imageview height to 40dp and then i give margin top -20 dp so that image will overlay half as you need on background image.
I did not run this code so if you face any issues just let me know i hope this works well for you..

Animating View in RelativeLayout from within a ScrollView

I am testing a feature where I would like to animate a view from a ScrollView. I think providing a sample layout would be much easier to understand, so here it goes:

Summarizing it: main parent is a LinearLayout, containing a header (another LinearLayout), and a ScrollView. In this ScrollView I got a bunch of Views, and over them, there is another View (a FrameLayout containing a Button in this testing case) which I would like to animate later.
The problem is (or at least what I think of): somehow, the height of the RelativeLayout is computed as wrapped content, and animating that View to the bottom of the screen won't display it, as it goes beyond its parent computed height.
In case it would be relevant, this is the tested animation being fired when I click the button:
AnimatorSet animSet = new AnimatorSet();
ObjectAnimator animToBottom = ObjectAnimator.ofFloat(frameCart, "translationY", 200);
animSet.play(animToBottom);
animSet.setDuration(300);
animSet.start();
