Remove View after animation - android

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);

anim.addAnimation(opacity1);

FragmentManager needing extra requestLayout

I built a view that contains a EditText as a submit button, therefore it's not focusable in touch mode, the text is centered and it has a background color. Then, I created a fragment with this button.
When this fragment is the first one to be placed in the container to be drawn, the text is centered in the edit text as expected. However, if use an click event to replace this fragment with another fragment that contains it's own submit button, the text is not centered, let alone aligned to the left or to the right. It's not aligned at all.
After put a Hander to add a delay for requesting the layout after 5ms where I create view to be placed in the fragment, the text get centered properly. I realize that for some reason the fragment transaction is needing an extra call for requestLayout.
I isolated the code that is causing the problem. By doing this I realized that the problem is somehow related with the way I handle typefaces in my TestTextField.java. I pasted right bellow.
What could be possibly causing that? Why? If it is something wrong with my code, why it works to the first fragment I placed in the screen, but it does not work with the other ones?

I came to a solution that doesn't require to call an extra requestLayout, I believe this is the right way to solve this problem.
updateMinHeight and super.onMeasure are in the wrong order in the onMeasure method. The correct way is:
#Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
updateMinHeight();
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}
For me, this order above makes sense since updateMinHeight can actually change the measured size of the widget. Though this answer shows how to solve, I can't understand why the problem happens and how would this affect only the text position in very specific cases, such as to the first fragment displayed.

SplashScreen - Time to close

I deployed a splash screen in my application with an Internet code, everything is working but cannot set a time for this activity close and open the main application could help me. I've tried the shape of the handler but closes the application after time.

Take a look at this tutorial
http://www.androidhive.info/2013/07/how-to-implement-android-splash-screen-2/
Use Handler
new Handler().postDelayed(new Runnable() {
/*
* Showing splash screen with a timer. This will be useful when you
* want to show case your app logo / company
*/
#Override
public void run() {
// This method will be executed once the timer is over
// Start your app main activity
Intent i = new Intent(SplashScreen.this, MainActivity.class);
startActivity(i);
// close this activity
finish();
}
}, SPLASH_TIME_OUT);
SPLASH_TIME_OUT is time in milliseconds. Start your next activity inside run method

How to call onclicklistner of animated image android

i am working on android app
in which i have an animated image.
my code is
Display display = getWindowManager().getDefaultDisplay();
int width = display.getWidth()/2;
left = new TranslateAnimation(0, hight, width, hight);
left1= new TranslateAnimation( 480, 10, 0, 10);
left.setDuration(2000);
left.setAnimationListener(this);
b1 =(ImageView)findViewById( R.id.balloon);
b1.setOnClickListener(this);
b1.startAnimation(left);
#Override
public void onClick(View v) {
Toast.makeText(this, "Clicked", 27).show();
}
using this code i am able to animate ballon or my picture but i the onclick lisnter only works when animation is completed i want onclicklistner should work during animation how to do this.
sorry for bad english
Override onAnimationStart and onAnimationEnd functions in your AnimationListener. Keep a variable to check whether animation is playing when the image clicked.

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.

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.
