I'm trying to do a simple fade-out animation for my "custom" media controller.
The problem I'm having is that the layout does not fade-out, it just disappears after a second (as if I would set the Visibility to GONE with a 1 second delay).
This is my function:
private void fadeOut(final View view) {
final AlphaAnimation fadeOutAnimation = new AlphaAnimation(1.0F, 0.0F);
fadeOutAnimation.setDuration(1000);
fadeOutAnimation.setAnimationListener(new AnimationListener() {
#Override
public void onAnimationStart(Animation animation) {
}
#Override
public void onAnimationRepeat(Animation animation) {
}
#Override
public void onAnimationEnd(Animation animation) {
view.setVisibility(View.GONE);
}
});
view.startAnimation(fadeOutAnimation);
}
And the layout that I'm trying to hide:
<RelativeLayout
android:id="#+id/videoControllerContainer"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:layout_marginBottom="0dp"
android:alpha="50"
android:background="#color/DarkGrey" >
<ImageButton
android:id="#+id/playVideoButton"
android:layout_width="wrap_content"
android:layout_height="50dip"
android:layout_alignParentLeft="true"
android:background="#null"
android:contentDescription="#string/playButton"
android:scaleType="fitCenter"
android:src="#drawable/play" />
<ImageButton
android:id="#+id/fullScreenVideoButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:layout_marginRight="20dp"
android:background="#null"
android:contentDescription="#string/fullscreen"
android:src="#drawable/fullscreen" />
</RelativeLayout>
It's worth mentioning that all this is being used inside a fragment.
I'm hoping that someone with a bit more experience will take the time and let me know what I'm doing wrong.
I think you should have this in an anim xml file where you would want this:
<set xmlns:android="http://schemas.android.com/apk/res/android">
<alpha android:fromAlpha="1.0" android:toAlpha="0.0"
android:interpolator="#android:anim/accelerate_interpolator"
android:duration="1000"/>
</set>
I think your problem is that the interpolator isn't defined. So try to put this line's equivalent in your code:
android:interpolator="#android:anim/accelerate_interpolator"
Hope it helps
EDIT: did a little research, it looks like you want to say
fadeOutAnimation.setInterpolator(new AccelerateInterpolator());

I was using the following dependency, but I am not going to use it anymore as I have noticed that it is deprecated: dependency I was using
As you can see, the About of this depencency, says the following:
Deprecated because of the performance not fine. Android custom shadow
view, can replace your CardView
I am trying to replace what I was using from that dependency for the Android custom shadow view as the dependency About says, but I don´t know how could I do it.

LinearLayout.startAnimation(Animation);

In the main.activity.java the above function is run:
showCardView();

I'm working on an Android application at my work and I am having a problem.
I need to know how I can use the Onchanged and OnTouch methods for the same button with conditions?
For example: If my button is on left than you can only touch it to do something and if it is on right than you can use it as a spinner.
I will suggest to use an image Button for both the case. As your requirement, use image Button as a normal Button when in left-side and spinner when on right. You can make use of a variable "i" to be set if it is in right side. Change the method if it is reset.
<ImageButton
android:id="#+id/imageButtonSpinner"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="15dp"
/>
Then define your spinner in terms of what you need inside it. Like this may be....
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/spinnerLayout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical" >
<ImageButton
android:id="#+id/love"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
<ImageButton
android:id="#+id/hem"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
<ImageButton
android:id="#+id/love"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
</LinearLayout>
In the mainActivity
protected void onCreate(Bundle savedInstanceState) {
...
addListenerToSpinnerButton();
}
private void addListenerToSpinnerButton(){
spinnerButton = (ImageButton) findViewById(R.id.imageButtonSpinner);
spinnerButton.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v){
if(p != null)
showSpinner(MainActivity.this, p);
}
});
}
Our application makes heavy use of webviews. When testing on ICS, we noticed that we need to set the application property hardwareAccelerated="true". However, doing this caused a few other bugs in our application, most of which we have fixed. We are still having problems getting our 'slide-in' animation working. Without any code changes, the animation simply does a 'reveal' type animation rather than sliding. We have tries a few different things:
Adding a small alpha transition (.99->1). This changes the 'reveal' to a 'slide' but causes some weird artifacts on the screen sometimes.
using hardware layers during the animation. This doesn't work consistently.
using software layers during the animation. This works, but causes a slow redraw after the slide-in animation completes for the first time.
Approach 3 is the most promising, but we have not figured out how to avoid the redraw. We have created a small test case using a sample project with a single activity:
activity class:
int accelValue = View.LAYER_TYPE_NONE; //hack
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
addClickListenerAnimation(R.id.buttonhl, R.anim.to_left, View.VISIBLE, View.INVISIBLE);
addClickListenerAnimation(R.id.buttonhr, R.anim.to_right, View.VISIBLE, View.INVISIBLE);
addClickListenerAnimation(R.id.buttonsl, R.anim.from_left, View.INVISIBLE, View.VISIBLE);
addClickListenerAnimation(R.id.buttonsr, R.anim.from_right, View.INVISIBLE, View.VISIBLE);
final Button b = (Button) findViewById(R.id.accel);
b.setOnClickListener(
new View.OnClickListener()
{
#Override
public void onClick(View v)
{
accelValue = ++accelValue % 3;
b.setText(accelValue == 0 ? "NONE" : accelValue == 1 ? "S/W" : "H/W");
}
});
}
private void addClickListenerAnimation(int buttonId, final int animId, final int startVis, final int endVis)
{
Button b = (Button) findViewById(buttonId);
b.setOnClickListener(
new View.OnClickListener()
{
#Override

{
final WebView wv = (WebView) findViewById(R.id.webview);
final View layout = findViewById(R.id.frame);
Animation a = AnimationUtils.loadAnimation(getApplicationContext(), animId);
a.setDuration(500);
a.setAnimationListener(new AnimationListener()
{
#Override

{
Log.i("sb", "layer type was " + wv.getLayerType());
Log.i("sb", "llayout layer type was " + layout.getLayerType());

Log.i("sb", "setting layer type " + accelValue);

Well, if you are trying to support ICS and onward, you can use the new Animation APIs as they are much easier to use and I believe will be very smooth.
Here are two links to take a look into this API:
this and this
And if you want to use this API for older versions, try NineOldAndroids
Edit: Try setting the WebView's Layer to a Software one:
web.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
It stopped the flickering but you lose hardware acceleration inside the view. I am not sure but I guess that for stuff like animation the view would still be considered as having hardware acceleration since its "container" still does. But I could be completely wrong too.
it worked fine for me using
web.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
the flickering issue was solved
From you description it seems like that's the same problem I had, though I'm not completely sure of that. At first I used your solution, but now I have one that works even better. I simply set
android:alwaysDrawnWithCache="true"
on the web view. That get's rid of all flickering and wrong drawing.
I hope it helps!
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.
