Remove View after animation

I have a view that does an animation and then should be removed or at least sent to the back so i can reuse it. I'm having trouble attaching a listener to it.
I've been stuck on this for about 2 weeks so any help at all is really appreciated.
I'm just trying to get the card to fling off the screen, disappear and then be deleted.

Is it just me or does making an Android app feel like you're constantly swimming against the current in a river.
Edit: If you want to see real improvement, explain why you think this is a bad question rather than just down voting.

I took out onAnimationEnd and just put the removeAllView method outside of it and it worked. Honestly I have no idea how this works. One would imagine that if you remove a View it cannot have an animation work on it.
private void flingCardAway(){
View currentAnimCardContainer = findViewById(R.id.card_container);
ViewCompat.setTranslationZ(currentAnimCardContainer, 1.0f);
AnimationSet anim = new AnimationSet(true);
RotateAnimation rotate1 = new RotateAnimation(0,-45, Animation.RELATIVE_TO_SELF,0.5f , Animation.RELATIVE_TO_SELF, 0.5f );
rotate1.setStartOffset(1);
rotate1.setDuration(400);
anim.addAnimation(rotate1);
TranslateAnimation trans1 = new TranslateAnimation(Animation.RELATIVE_TO_PARENT, -0.0f, Animation.RELATIVE_TO_PARENT, -1.5f, Animation.RELATIVE_TO_PARENT, 0.0f, Animation.RELATIVE_TO_PARENT, -0.5f);
trans1.setStartOffset(1);
trans1.setDuration(550);
anim.addAnimation(trans1);
AlphaAnimation opacity1 = new AlphaAnimation(1.0f, 0.0f);
opacity1.setStartOffset(300);
opacity1.setDuration(600);
anim.addAnimation(opacity1);
currentAnimCardContainer.startAnimation(anim);
mCardFrame.removeAllViews();
}

Android - RotateAnimation onClick button restart itself

this is the java code to rotate an image when click on button. Image rotate it's perfect but if I click button again when rotation is not ended the animation restart itself, not end the animation. How can I wait the end of the animation? I found Animation.AnimationListener, I think that onAnimationEnd works great for me, but I'm not be able to integrate it in my code... please help me :-)

}

You have to take a boolean variable which tracks whether animation is in progress or not. then use this variable in animation listener and button click as below code
buttonRotateCenter.setOnClickListener(new Button.OnClickListener() {
public void onClick(View arg0) {
if(!anim_in_progress)
floatingImage.startAnimation(animationRotateCenter);
}
});
animationRotateCenter.setAnimationListener(new anim_listener());
}
boolean anim_in_progress=false;
class anim_listener implements AnimationListener
{
#Override
public void onAnimationEnd(Animation arg0) {
anim_in_progress=false;
}
#Override
public void onAnimationRepeat(Animation arg0) {
// TODO Auto-generated method stub
}
#Override
public void onAnimationStart(Animation arg0) {
// TODO Auto-generated method stub
anim_in_progress=true;
}
}

Never tried this, but might work
buttonRotateCenter.setOnClickListener(new Button.OnClickListener() {
public void onClick(View arg0) {
if(!floatingImage.hasTransientState())
floatingImage.startAnimation(animationRotateCenter);
}
});

I want to change from an xml layout to surfaceview using java

OK so I'm using xml to set this menu which is supported by the following java code
package starting.rt;
import java.util.List;
import java.util.Random;
import android.app.Activity;
import android.content.Intent;
import android.content.pm.PackageManager;
import android.content.pm.ResolveInfo;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.TextView;
public class Menu extends Activity implements OnClickListener{
View.OnTouchListener gestureListener;
TextView display;
Button begin;
Button random;
Button game;
TextView counter;
Button next;
Button previous;
Button moreapps;
Button rate;
Random myRandom;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(starting.rt.R.layout.menu);
begin = (Button) findViewById(starting.rt.R.id.Begin);
random = (Button) findViewById(starting.rt.R.id.Random);
display = (TextView) findViewById(starting.rt.R.id.tvResults);
counter = (TextView) findViewById(starting.rt.R.id.tvCounter);
next = (Button) findViewById(starting.rt.R.id.Next);
previous = (Button) findViewById(starting.rt.R.id.Previous);
moreapps = (Button)findViewById(R.id.More);
rate = (Button) findViewById(R.id.rate);
game = (Button) findViewById(R.id.game);
// display.setOnTouchListener(this.gestureListener);
begin.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Intent openStartingPoint = new Intent("starting.rt.RelationshipTipsActivity");
startActivity(openStartingPoint);
}});
moreapps.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Intent goToMarket;
goToMarket = new Intent(Intent.ACTION_VIEW, Uri.parse("market://search?q=pub:\"Wompa\""));
startActivity(goToMarket);
}});
game.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Intent openStartingPoint = new Intent("starting.rt.GameView");
startActivity(openStartingPoint);
}});
rate.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse("market://details?id=" + getPackageName()));
startActivity(i);
}});}
public void onClick(View v) {
// TODO Auto-generated method stub
}
}
Now what's supposed to be happening is when they click on the game which starts a new java class called GameView it crashes on clicked. Every other button works.
This is the code from GameView
package starting.rt;
import java.util.ArrayList;
import java.util.List;
import android.content.Context;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.graphics.Canvas;
import android.graphics.Color;
import android.view.MotionEvent;
import android.view.SurfaceHolder;
import android.view.SurfaceView;
public class GameView extends SurfaceView {
private GameLoopThread gameLoopThread;
private List<Sprite> sprites = new ArrayList<Sprite>();
private List<TempSprite> temps = new ArrayList<TempSprite>();
private long lastClick;
private Bitmap bmpBlood;
public GameView(Context context) {
super(context);
gameLoopThread = new GameLoopThread(this);
getHolder().addCallback(new SurfaceHolder.Callback() {
public void surfaceDestroyed(SurfaceHolder holder) {
boolean retry = true;
gameLoopThread.setRunning(false);
while (retry) {
try {
gameLoopThread.join();
retry = false;
} catch (InterruptedException e) {}
}
}
public void surfaceCreated(SurfaceHolder holder) {
createSprites();
gameLoopThread.setRunning(true);
gameLoopThread.start();
}
public void surfaceChanged(SurfaceHolder holder, int format,
int width, int height) {
}
});
bmpBlood = BitmapFactory.decodeResource(getResources(), R.drawable.blood1);
}
private void createSprites() {
sprites.add(createSprite(R.drawable.bad1));
// sprites.add(createSprite(R.drawable.bad2));
// sprites.add(createSprite(R.drawable.bad3));
// sprites.add(createSprite(R.drawable.bad4));
// sprites.add(createSprite(R.drawable.bad5));
// sprites.add(createSprite(R.drawable.bad6));
// sprites.add(createSprite(R.drawable.good1));
// sprites.add(createSprite(R.drawable.good2));
// sprites.add(createSprite(R.drawable.good3));
// sprites.add(createSprite(R.drawable.good4));
// sprites.add(createSprite(R.drawable.good5));
// sprites.add(createSprite(R.drawable.good6));
}
private Sprite createSprite(int resouce) {
Bitmap bmp = BitmapFactory.decodeResource(getResources(), resouce);
return new Sprite(this, bmp);
}
#Override
protected void onDraw(Canvas canvas) {
canvas.drawColor(Color.BLACK);
for (int i = temps.size() - 1; i >= 0; i--) {
temps.get(i).onDraw(canvas);
}
for (Sprite sprite : sprites) {
sprite.onDraw(canvas);
}
}
#Override
public boolean onTouchEvent(MotionEvent event) {
if (System.currentTimeMillis() - lastClick > 300) {
lastClick = System.currentTimeMillis();
float x = event.getX();
float y = event.getY();
synchronized (getHolder()) {
for (int i = sprites.size() - 1; i >= 0; i--) {
Sprite sprite = sprites.get(i);
if (sprite.isCollition(x, y)) {
sprites.remove(sprite);
temps.add(new TempSprite(temps, this, x, y, bmpBlood));
break;
}
}
}
}
return true;
}
}
The GameView calls a few other classes for things part of the game but it crashes before it can start. I think it's crashing because it's switching from xml layout to the java surfaceview. Help would be appreciated :) Thanks!

First of all, you should always post in your questions the stacktrace with the exception from the Logcat if your app crashes.
You can't start a SurfaceView directly, instead your custom SurfaceView must be embedded in an Activity like any other view in android. For example:
public class GameViewActivity extends Activity {
#Override
public void onCreate(Bundle savedInstance) {
super.onCreate(savedInstance);
setContentView(new GameView(this));
}
}

How to start activity on animation end

This is my first app and i need to start new activity when the animation ends. what do I need to do? My code:
package com.lineage.goddess;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.WindowManager;
import android.view.animation.Animation;
import android.view.animation.AnimationUtils;
import android.widget.TextView;
public class LineageSplashActivity extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
startAnimation();
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
}
private void startAnimation() {
// TODO Auto-generated method stub
TextView logo1= (TextView) findViewById(R.id.TextView1);
Animation fade1= AnimationUtils.loadAnimation(this, R.anim.fade_in);
logo1.startAnimation(fade1);
TextView logo2= (TextView) findViewById(R.id.TextView2);
Animation fade2= AnimationUtils.loadAnimation(this, R.anim.fade_in);
logo2.startAnimation(fade2);
TextView logo3= (TextView) findViewById(R.id.TextView3);
Animation fade3= AnimationUtils.loadAnimation(this, R.anim.fade_in);
logo3.startAnimation(fade3);
TextView logo4= (TextView) findViewById(R.id.TextView4);
Animation fade4= AnimationUtils.loadAnimation(this, R.anim.fade_in2);
logo4.startAnimation(fade4);}
public void onAnimationEnd() {
Intent i = new Intent( LineageSplashActivity.this, LineageMenuActivity.class );
LineageSplashActivity.this.startActivity( i );
;
}
}

Set an AnimationListener to the animation you want to use to start your Activity.
myAnimation.setAnimationListener(new AnimationListener() {
public void onAnimationStart(Animation animation) {}
public void onAnimationRepeat(Animation animation) {}
public void onAnimationEnd(Animation animation) {
Intent i = new Intent( LineageSplashActivity.this, LineageMenuActivity.class );
LineageSplashActivity.this.startActivity( i );
}
}
So, your code will be like this:
package com.lineage.goddess;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.WindowManager;
import android.view.animation.Animation;
import android.view.animation.AnimationUtils;
import android.widget.TextView;
public class LineageSplashActivity extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
startAnimation();
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
}
private void startAnimation() {
// TODO Auto-generated method stub
TextView logo1= (TextView) findViewById(R.id.TextView1);
Animation fade1= AnimationUtils.loadAnimation(this, R.anim.fade_in);
logo1.startAnimation(fade1);
TextView logo2= (TextView) findViewById(R.id.TextView2);
Animation fade2= AnimationUtils.loadAnimation(this, R.anim.fade_in);
logo2.startAnimation(fade2);
TextView logo3= (TextView) findViewById(R.id.TextView3);
Animation fade3= AnimationUtils.loadAnimation(this, R.anim.fade_in);
logo3.startAnimation(fade3);
TextView logo4= (TextView) findViewById(R.id.TextView4);
Animation fade4= AnimationUtils.loadAnimation(this, R.anim.fade_in2);
face4.setAnimationListener(new AnimationListener() {
public void onAnimationStart(Animation animation) {}
public void onAnimationRepeat(Animation animation) {}
public void onAnimationEnd(Animation animation) {
Intent i = new Intent( LineageSplashActivity.this, LineageMenuActivity.class );
LineageSplashActivity.this.startActivity( i );
}
}
logo4.startAnimation(fade4);
}
}

Your code made my eye's bleed, so I fixed it as much as I could:
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.WindowManager;
import android.view.animation.Animation;
import android.view.animation.Animation.AnimationListener;
import android.view.animation.AnimationUtils;
public class LineageSplashActivity extends Activity implements AnimationListener {
private static final int NUMBER_OF_ANIMATIONS = 4;
private int animationFinishedCount = 0;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
startAnimations();
}
private void startAnimations() {
Animation fade = AnimationUtils.loadAnimation(this, R.anim.fade_in);
fade.setAnimationListener(this);
findViewById(R.id.TextView1).startAnimation(fade);
findViewById(R.id.TextView2).startAnimation(fade);
findViewById(R.id.TextView3).startAnimation(fade);
findViewById(R.id.TextView4).startAnimation(fade);
}
#Override
public void onAnimationEnd(Animation animation) {
// When all animations have finished - start the next activity
if(++animationFinishedCount == NUMBER_OF_ANIMATIONS){
Intent intent = new Intent( this, LineageMenuActivity.class );
startActivity( intent );
}
}
#Override
public void onAnimationStart(Animation animation) {
// Nothing
}
#Override
public void onAnimationRepeat(Animation animation) {
// Nothing
}
}
And if it's not a mis-type and you actually need a different animation for the 4th textview you can remove the count check and just add the animation listener to that individual animation.

How to make a group of clickable graphical object?

my question is how can I make a set of clickable images on Android.
I can make one clickable sphere by using ShapeDrawable, however I want to make more than one at once and still be able to get clicks in all of them.
Moreover I want to position them on screen at my will, instead of auto positioned as with layouts.
The number of spheres can change as can the places.
This is the code I use to make one:
Main.java
package com.teste;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.LinearLayout;
import android.widget.Toast;
public class Main extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
LinearLayout layout = new LinearLayout(this);
CustomDrawableView mCustomDrawableView = new CustomDrawableView(this, 100, 100, 50, 50, 0xff74AC23);
CustomDrawableView mCustomDrawableView2 = new CustomDrawableView(this, 10, 10, 50, 50, 0xffffffff);
mCustomDrawableView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(getBaseContext(), "Clicked green ball", Toast.LENGTH_SHORT).show();
}
});
mCustomDrawableView2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(getBaseContext(), "Clicked white ball", Toast.LENGTH_SHORT).show();
}
});
layout.addView(mCustomDrawableView);
layout.addView(mCustomDrawableView2);
setContentView(layout);
}
}
CustomDrawableView.java
package com.teste;
import android.content.Context;
import android.graphics.Canvas;
import android.graphics.drawable.ShapeDrawable;
import android.graphics.drawable.shapes.OvalShape;
import android.view.View;
import android.view.ViewGroup.LayoutParams;
public class CustomDrawableView extends View {
private ShapeDrawable mDrawable;
public CustomDrawableView(Context context, int i, int j, int k, int l, int m) {
super(context);
LayoutParams params = new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
super.setLayoutParams(params);
mDrawable = new ShapeDrawable(new OvalShape());
mDrawable.getPaint().setColor(m);
mDrawable.setBounds(i, j, i + k, j + l);
}
protected void onDraw(Canvas canvas) {
mDrawable.draw(canvas);
}
}
Hope you can help :)

It should be as easy as making your clas
CustomDrawableView extends View implements OnClickListener {
// all your code here
public void onClick(View v) {
// your callback function here
}
}
Take a look at one example I wrote some time ago in this answer: Android onClick method doesn't work on a custom view
