I created simple animation in CustomView to transition beetwen activities. Everything is fine except animation smooth. There are visible lags when circle radius is increased. How can I performance animation to avoid lags?
public class CircleAnimationView extends View {
...
public void startAnimation(int x, int y) {
startX = x;
startY = y;
baseAnimator = ObjectAnimator.ofFloat(this, "baseRadius", 0, maxRadius)
.setDuration(1000);
baseAnimator
.setInterpolator(new AccelerateDecelerateInterpolator());
baseAnimator.start();
finalAnimator = ObjectAnimator.ofFloat(this, "finalRadius", 0, maxRadius)
.setDuration(2000);
finalAnimator
.setInterpolator(new AccelerateDecelerateInterpolator());
if(listener!=null)
finalAnimator.addListener(listener);
finalAnimator.start();
}
public void setBaseRadius(final float radius) {
radiusBase = radius;
invalidate();
}
public void setFinalRadius(final float radius) {
radiusFinal = radius;
invalidate();
}
#Override
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
if (isInEditMode()) {
return;
}
canvas.drawCircle(startX, startY, radiusBase, basePaint);
canvas.drawCircle(startX, startY, radiusFinal, finalPaint);
}
};
I used view in xml:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/main_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<RelativeLayout
android:id="#+id/content_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center">
</RelativeLayout>
<pl.org.ldi.challenge.views.CircleAnimationView
android:id="#+id/circle_animation"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:base_color="#color/blue"
app:final_color="#color/white"/>
</RelativeLayout>
Edit:
I check .trace file from animation, and it looks like that drawing large circle takes too much time - method GLES20Canvas.nDrawDisplayList
After set:
finalAnimator.setFrameDelay(0);
baseAnimator.setFrameDelay(0);
animation looks smoothly. Thanks for advice!
You can use a handler to call invalidate by help of its postDelayed() method. Call this methods at regular intervals throughout your animations duration. You can calculate the radius according by the ratio of current_time/total_time and multiplied with the maximim radius you want.

I need to implement a circular reveal animation after the transition between 2 fragments is finished so that the ImageButton (android:id="#+id/update_profile_pic") will be revealed with a nice animation
The problem is that it doesn't work as it should:
setEnterSharedElementCallback(new SharedElementCallback() {
Handler handler = new Handler();
#Override
public void onSharedElementEnd(List<String> sharedElementNames,
List<View> sharedElements,
List<View> sharedElementSnapshots) {
handler.postDelayed(new Runnable() {
#Override
public void run() {
update_profile_pic.setVisibility(View.GONE);
// get the center for the clipping circle
int cx = update_profile_pic.getWidth() / 2;
int cy = update_profile_pic.getHeight() / 2;
// get the final radius for the clipping circle
float finalRadius = (float) Math.hypot(cx, cy);
// create the animator for this view (the start radius is zero)
Animator anim = ViewAnimationUtils.createCircularReveal(update_profile_pic, cx, cy, 0f, finalRadius);
// make the view visible and start the animation
update_profile_pic.setVisibility(View.VISIBLE);
anim.start();
}
}, 600);
}
});
When I try this animation in a button click listener, the button needs to be clicked twice to make the animation work
The layout is like this:

Any help?
try to set visibility of your ImageButton to invisible instead of gone initially.
In my sample project i have a linear layout, its height is set to wrap content in xml and there is also a fragment below it which takes all the remaining space. The fragment contains a button which when clicked will remove the fragment and the height of the linear layout is set to match parent. I tried adding android:animateLayoutChanges="true" but the transition from wrap_content to match_parent is not smooth. How can i animate from android:layout_height="wrap_content" to android:layout_height="match_parent"
Here is the layout
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/bg"
android:orientation="vertical"
android:id="#+id/layoutRoot"
tools:context=".MainActivity">
<LinearLayout
android:layout_width="match_parent"
android:id="#+id/cloudHolder"
android:orientation="vertical"
android:animateLayoutChanges="true"
android:gravity="center"
android:layout_height="wrap_content">
<ImageButton
android:layout_width="100dp"
android:layout_gravity="center"
android:layout_height="100dp"
android:background="#drawable/play"/>
</LinearLayout>
#tdjprog Answer with some edit
1 - Stritch
private void animateViewTostritch_height(final View target) {
int fromValue = 0;
// int fromValue = target.getHeight();
// int toValue = ((View) target.getParent()).getHeight();// matchparent
int toValue = (int) getResources().getDimension(R.dimen.dialog_header_height);//spesific hight
// int toValue = (int) (getResources().getDimension(R.dimen.dialog_header_height) / getResources().getDisplayMetrics().density);
ValueAnimator animator = ValueAnimator.ofInt(fromValue, toValue);
animator.setDuration(2000);
animator.setInterpolator(new DecelerateInterpolator());
animator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
#Override
public void onAnimationUpdate(ValueAnimator animation) {
target.getLayoutParams().height = (int) animation.getAnimatedValue();
target.requestLayout();
}
});
animator.start();
}
Call animateViewTostritch_height(your_View);
2 - Scale %
public void scaleView(View v, float startScale, float endScale) {
Animation anim = new ScaleAnimation(
1f, 1f, // Start and end values for the X axis scaling
startScale, endScale, // Start and end values for the Y axis scaling
Animation.RELATIVE_TO_SELF, 0f, // Pivot point of X scaling
Animation.RELATIVE_TO_SELF, 1f); // Pivot point of Y scaling
anim.setFillAfter(true); // Needed to keep the result of the animation
anim.setDuration(1000);
v.startAnimation(anim);
}
Call scaleView(your_View,0f,10f); // 10f match parent
You may need to try adding android:animateLayoutChanges="true" in the parent layout itself like for example:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/bg"
android:orientation="vertical"
android:animateLayoutChanges="true"
android:id="#+id/layoutRoot"
tools:context=".MainActivity">
<LinearLayout
android:layout_width="match_parent"
android:id="#+id/cloudHolder"
android:orientation="vertical"
android:gravity="center"
android:layout_height="wrap_content">
<ImageButton
android:layout_width="100dp"
android:layout_gravity="center"
android:layout_height="100dp"
android:background="#drawable/play"/>
</LinearLayout>
</LinearLayout>
If the above code doesn't work, you might need to take a look at:
Animation of height of LinearLayout container with ValueAnimator
Or
Animation in changing LayoutParams in LinearLayout
I think relying on animateLayoutChanges isn't a good idea. Try below code instead.
import android.view.ViewPropertyAnimator;
// In your activity
private int parentHeight;
private int childHeight;
private float childScaleFactor;
//In onCreate()
mChildView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
#Override
public void onGlobalLayout() {
parentHeight = mParentView.getMeasuredHeight();
childHeight = mChildView.getMeasuredHeight();
childScaleFactor = parentHeight/childHeight;
}
});
mChildView.animate()
.scaleY(childScaleFactor)
.setDuration(500)
.start();
If this doesn't work, refer to this answer on another post
try this:
private void animateViewToMatchParent(final View target) {
int fromValue = target.getHeight();
int toValue = ((View) target.getParent()).getHeight();
ValueAnimator animator = ValueAnimator.ofInt(fromValue, toValue);
animator.setDuration(250);
animator.setInterpolator(new DecelerateInterpolator());
animator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
#Override
public void onAnimationUpdate(ValueAnimator animation) {
target.getLayoutParams().height = (int) animation.getAnimatedValue();
target.requestLayout();
}
});
animator.start();
}
I want to give the map a nice looking rounded corners as the two boxes below it have.
I can't do it with the map fragment it self because there is not a background property to a
fragment.
setting the map inside a layout and setting it background to a rounded shape didn't help me
as well and this is the result:
I could merge the map but this would make it smaller and i would like to avoid it.
EDIT:
#Ryan this is the new result #2:
I guess this is not bad, no even close to the corners on the other boxes,
but still not bad with a little more work a could get somewhere close i just dont have a normal image editor.
but one thing that still bothers me now is the separation between the "Location" Textview and the map it's self. could i painted the patch in other way so that there was now distance? this is how i did it:
Well I have finally figured this out:
this is what i used for the patch:
Thanks.
I know it's an old post, but you can try using Cards like so:
<android.support.v7.widget.CardView
android:layout_width="300dp"
android:layout_height="350dp"
android:layout_gravity="center_horizontal|center_vertical"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"
android:layout_marginTop="20dp"
app:cardCornerRadius="12dp"
app:cardElevation="12dp">
<fragment
android:id="#+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</android.support.v7.widget.CardView>
I haven't tried this, but I'd put a view with rounded corners and a transparent middle on top of the mapView / mapFragment.
That is, put the mapFragment and the rounded corner view in a FrameLayout with both filling the FrameLayout, then make the middle of the rounded corner view transparent.
For further clarification, you could do it in a layout as follows:-
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<fragment
xmlns:map="http://schemas.android.com/apk/res-auto"
android:id="#+id/mapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.google.android.gms.maps.MapFragment" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/rounded_background"
android:orientation="vertical" >
</LinearLayout>
</FrameLayout>
The rounded_background is a 9-patch with rounded corners and a transparent middle. E.g.
Hope that helps,
Ryan
The easiest way is to wrap the map fragment inside a FrameLayout along with an ImageView. The Imageview would display a rounded rectangle on top of the map fragment. In its simplest form you will see the map fragment inside the rounded rectangle with its corners sticking out of the rounded rectangle because the map view itself is not rounded. To overcome this visual oddity simply apply a layout_margin value on map fragment. The value should be equal to the rectangle's border width.
<FrameLayout
android:id="#+id/map_container"
android:layout_width="wrap_content"
android:layout_height="340dp" >
<fragment
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_margin="3dp"
android:name="com.google.android.gms.maps.SupportMapFragment"/>
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="#drawable/map_bg_box" />
</FrameLayout>
The rectangle drawable is defined as an xml shape as below
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<stroke android:width="3dp"
android:color="#ff000000" />
<corners android:bottomRightRadius="7dp" android:bottomLeftRadius="7dp"
android:topLeftRadius="7dp" android:topRightRadius="7dp"/>
</shape>
Notice the stroke width of the rectangle is 3dp that is exactly the same value we applied to the layout_margin property of the map fragment. The result is a nicely round cornered map fragment as shown in the screenshot below
Wrap the map fragment in this layout:
package com.example.yourpackage;

In layout will be like this:
<com.example.yourpackage.RoundedLayout
android:id="#+id/maplayout"
android:layout_width="match_parent"
android:layout_height="200dp"
android:layout_margin="20dp">
<fragment
android:id="#+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="200dp"
tools:context="com.example.yourpackage.MapsMarkerActivity"/>
</com.example.yourpackage.RoundedLayout>
In code can be like this for a round shape with border:
RoundedLayout rl = (RoundedLayout) findViewById(R.id.maplayout);
rl.setShapeCircle(true);
rl.showBorder(true);
rl.setBorderWidth(2);
This layout can be used to shape any view.
It's incredible how google is incapable of making competent (usable) complete demos for it's android API.
For other people looking into this, I just tackled this using GoogleMap.snapshot and manipulating the bitmap result with this stack over flow answer:
How to make an ImageView with rounded corners?
Mind you this is only valid if you are going to have a static map that is not going to be interacted with.
Make sure you take the snap shot after the map is loaded.
I updated the image view helper code to draw with path to support rounding only some corners. ie. If you want to round only 2 of the corners.
You just need the path round rect function that takes a float[]
I show a progress bar until I get a callback from GoogleMap loaded listener than I take the snapshot.
If you take your snapshot too early you will get can't create bitmap with 0 width and height error.
Hope this helps someone looking for rounded corners or other weird shape in static map snapshot.
If you are only trying to target API 21 (Lollipop) and higher
This is the easiest way possible.
parentView.setClipToOutline(true);

I'm new on Android, and I am having trouble with the following:
I have an image of an empty test-tube (png or bmp).
And I need to draw lines on top of it to make the illusion that its being filled in with liquid.
I really don't know how to proceed. I have read google's documentation about animations, but that didn't help much.
I'd appreciate if you guys could give me some suggestions of how it can be done, and point to some tutorials/documentation that can help me.
Thanks in advance.
UPDATE:
The tube is not retangular, the bottom is oval.
I think I need to make the liquid fall into the test tube, then paint line by line, starting from the bottom. And I have to check for the borders of the tube (right and lef black pixels).
Any ideas of how this can be done?
UPDATE 2:
Here is the tube image: http://i61.tinypic.com/2nw0eb9.png
You can use a SurfaceView to draw what ever you want:
Basicly, you lock the surface's canvas by
Canvas canvas = mSurfaceView.getHolder().lockCanvas();
Then, use the canvas's methods to draw on it. canvas.drawBitmap, canvas.drawLine etc..
When you're finished lock the canvas with mSurfaceView.getHolder().unlockCanvasAndPost(canvas); and you're done.
here's an example from a quick google search:
http://android-coding.blogspot.co.il/2011/05/drawing-on-surfaceview.html
Best way to do this would be with a custom View. Make a new class, that extends View, then in its onDraw method first draw the picture, then draw your animations. If you want to do it by hand, you can do something like this:
private class TestTubeView extends View {
private int top = 0;
private Paint myPaint;
public MyView(Context context) {
super(context);
myPaint = new Paint();
myPaint.setColor(getResources().getColor(R.color.blue));
}
#Override
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
//First draw your bitmap
canvas.drawBitmap(BitmapFactory.decodeResource(getResources(), R.drawable.my_testtube), 0, 0, myPaint); //might need to use a different paint
//Then your "animation" as a static image, that has its position set from a variable, in this case "y" and "x"
canvas.drawRect(0, top, getWidth(), getHeight(), myPaint);
}
//In this method update your variables, that define the positions of your animated lines / bubbles
public boolean updateAnimation() {
top++;
invalidate();
//So it stops animationg
return top > getHeight();
}
}
Then in your layout you put it in like a normal view:
<com.example.TestTubeView
android:id="#+id/my_testtube"
android:layout_width="20dp"
android:layout_height="200dp" />
And then you animate it with a self-repeating Runnable:
final MyView testTube = findViewById(R.id.my_testtube);
final Handler myHandler = new Handler();
myHandler.post(new Runnable() {
#Override
public void run() {
if(testTube.updateAnimation()){
myHandler.postDelayed(this, 200);
}
}
});
You'll have to play around with sizes / heights and things like that though. Another way of doing this is with an ObjectAnimatior
Tube Drawable: (this is for test purposes. you will use your tube image)
tube.xml (drawable folder)
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
<stroke android:width="5dp" android:color="#ffccffff" />
<solid android:color="#00000000" />
</shape>

<?xml version="1.0" encoding="utf-8"?>

android:layout_height="220dp"
android:layout_gravity="center"
android:background="#drawable/tube"
android:onClick="fillJuice"
android:clickable="true" />
</FrameLayout>
</LinearLayout>
TubeAcivity.java
public class TubeActivity extends Activity {
LinearLayout orangeLL;
ImageView tubeIV;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.tube_activity);
orangeLL = (LinearLayout)findViewById(R.id.orangeJuiceLinearLayout);
tubeIV = (ImageView)findViewById(R.id.tubeImageView);
}
public void fillJuice(View view) {
ValueAnimator va = ValueAnimator.ofInt(0, tubeIV.getMeasuredHeight());
va.setDuration(1500);
va.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
public void onAnimationUpdate(ValueAnimator animation) {
Integer value = (Integer) animation.getAnimatedValue();
orangeLL.getLayoutParams().height = value.intValue();
orangeLL.requestLayout();

I haven't tried this, but I'd put a view with rounded corners and a transparent middle on top of the mapView / mapFragment.
That is, put the mapFragment and the rounded corner view in a FrameLayout with both filling the FrameLayout, then make the middle of the rounded corner view transparent.
For further clarification, you could do it in a layout as follows:-
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<fragment
xmlns:map="http://schemas.android.com/apk/res-auto"
android:id="#+id/mapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.google.android.gms.maps.MapFragment" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/rounded_background"
android:orientation="vertical" >
</LinearLayout>
</FrameLayout>
The rounded_background is a 9-patch with rounded corners and a transparent middle. E.g.
Hope that helps,

The easiest way is to wrap the map fragment inside a FrameLayout along with an ImageView. The Imageview would display a rounded rectangle on top of the map fragment. In its simplest form you will see the map fragment inside the rounded rectangle with its corners sticking out of the rounded rectangle because the map view itself is not rounded. To overcome this visual oddity simply apply a layout_margin value on map fragment. The value should be equal to the rectangle's border width.
<FrameLayout
android:id="#+id/map_container"
android:layout_width="wrap_content"
android:layout_height="340dp" >
<fragment
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_margin="3dp"
android:name="com.google.android.gms.maps.SupportMapFragment"/>
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="#drawable/map_bg_box" />
</FrameLayout>
The rectangle drawable is defined as an xml shape as below
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<stroke android:width="3dp"
android:color="#ff000000" />
<corners android:bottomRightRadius="7dp" android:bottomLeftRadius="7dp"
android:topLeftRadius="7dp" android:topRightRadius="7dp"/>
</shape>
Notice the stroke width of the rectangle is 3dp that is exactly the same value we applied to the layout_margin property of the map fragment. The result is a nicely round cornered map fragment as shown in the screenshot below
Wrap the map fragment in this layout:
package com.example.yourpackage;
import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Paint;
import android.graphics.Path;

// just a default for corner radius

mPaint.setAntiAlias(true);
mPaint.setStyle(Paint.Style.STROKE);

if (mBorderHalf == 0) {

}
mPaint.setStrokeWidth(mBorderWidth);
updateCircleBorder();
updateRectangleBorder();
invalidate();
}
public void setBorderColor(int color) {

// helper reusable vars, just IGNORE
private float halfWidth, halfHeight, centerX, centerY;

// just calculate both shapes, is not heavy
// rounded corners path
rect.left = 0;
rect.top = 0;
rect.right = w;
rect.bottom = h;
mPathCorners.reset();
mPathCorners.addRoundRect(rect, mCornerRadius, mCornerRadius, Path.Direction.CW);
mPathCorners.close();
// circle path
halfWidth = w / 2f;

mPathCircle.addCircle(centerX, centerY, Math.min(halfWidth, halfHeight), Path.Direction.CW);

mPathCornersBorder.reset();
mPathCornersBorder.addRoundRect(rectBorder, mCornerRadius - mBorderHalf, mCornerRadius -
mBorderHalf, Path.Direction.CW);
mPathCornersBorder.close();
}
}
In layout will be like this:
<com.example.yourpackage.RoundedLayout
android:id="#+id/maplayout"
android:layout_width="match_parent"
android:layout_height="200dp"
android:layout_margin="20dp">
<fragment
android:id="#+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="200dp"
tools:context="com.example.yourpackage.MapsMarkerActivity"/>
</com.example.yourpackage.RoundedLayout>
In code can be like this for a round shape with border:
RoundedLayout rl = (RoundedLayout) findViewById(R.id.maplayout);
rl.setShapeCircle(true);
rl.showBorder(true);
rl.setBorderWidth(2);
This layout can be used to shape any view.
It's incredible how google is incapable of making competent (usable) complete demos for it's android API.
For other people looking into this, I just tackled this using GoogleMap.snapshot and manipulating the bitmap result with this stack over flow answer:
How to make an ImageView with rounded corners?
Mind you this is only valid if you are going to have a static map that is not going to be interacted with.
Make sure you take the snap shot after the map is loaded.
I updated the image view helper code to draw with path to support rounding only some corners. ie. If you want to round only 2 of the corners.
You just need the path round rect function that takes a float[]
I show a progress bar until I get a callback from GoogleMap loaded listener than I take the snapshot.
If you take your snapshot too early you will get can't create bitmap with 0 width and height error.
Hope this helps someone looking for rounded corners or other weird shape in static map snapshot.
If you are only trying to target API 21 (Lollipop) and higher
This is the easiest way possible.
parentView.setClipToOutline(true);

Following #Nouman_Hanif post I ended up with a solution that looks quite good.
map_rounded_corner_overlay.xml:
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<stroke android:width="1dp"
android:color="#color/white" />
<corners android:radius="<your_desired_view_corner_radius>"/>
</shape>
My map xml file:
<?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">
<fragment
android:id="#+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_margin="1dp"
