Can I launch an Android animation in the onanimationEnd callback of the previous one?
I am attempting to launch one animation after another has finished by monitoring the onanimationEnd callback of the first on开发者_如何转开发e. However Android gives the following error when I attempt to do this:
Error - The method loadAnimation(Context, int) in the type AnimationUtils is not applicable for the arguments (new Animation.AnimationListener() {}, int)
I tried to use the answer in this post: ---Android Animation one after other Which I interpreted to mean that I should move everything except the start animation out of the callback, but when I do this I get the following error:
Error - Cannot refer to a non-final variable fade3 inside an inner class defined in a different method
What am I missing here???
******CODE FOR FIRST EXAMPLE**********
package com.smartproducts.dragracepro;
import android.content.Intent;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.util.TypedValue;
import android.view.Gravity;
import android.view.View;
import android.view.animation.Animation;
import android.view.animation.Animation.AnimationListener;
import android.view.animation.AnimationUtils;
import android.view.animation.LayoutAnimationController;
import android.widget.ImageView;
import android.widget.TableLayout;
import android.widget.TableRow;
import android.widget.TextView;
public class DragRaceProSplashActivity extends DragRaceProActivity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
//animate title fade in
TextView programtitle = (TextView) findViewById(R.id.TextViewTopTitle);
Animation fade1 = AnimationUtils.loadAnimation(this,R.anim.fade_in);
programtitle.startAnimation(fade1);
//show introduction and logo for Smart Shocks
fade1.setAnimationListener(new AnimationListener(){
@Override
public void onAnimationEnd(Animation fade1)
{
***************
ERROR IS HERE> Animation fade3 = AnimationUtils.loadAnimation(this,R.anim.fade_in2); ***************
ImageView sslogo = (ImageView) findViewById(R.id.ImageView03);
sslogo.setVisibility(View.VISIBLE);
sslogo.startAnimation(fade3);
}
@Override
public void onAnimationRepeat(Animation animation) {}
@Override
public void onAnimationStart(Animation animation) {}
});
}
Animation fade3 = AnimationUtils.loadAnimation(this,R.anim.fade_in2);
this
is referring to the animation instead of your context as your calling it inside of a listener, If you want to use this code then you need to create a global variable of your context and use that variable in place of this
