私はちょっと混乱しています...アニメーションの後、スプラッシュ画面は、次の.javaアクティビティファイルを操作するためのインテント関数を開始するはずですが、エミュレータのスプラッシュ画面の後に実行すると、作業。私はLogcatをオープンし、java.lang.nullpointerと実行時例外がPause機能で実行されている程度に何かを言いました...誰も私にこのことを説明できますか？ありがとう。Android：次の.javaに移行する際の問題？
package com.unicorn.test.whee;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.animation.Animation;
import android.view.animation.Animation.AnimationListener;
import android.view.animation.AnimationUtils;
import android.widget.ImageView;
public class SplashScreenPear extends Activity {
ImageView pearfade;
/** Called when the activity is first created. */
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.pear); }
private void startAnimating(){
Animation pearfadeact = AnimationUtils.loadAnimation(this, R.anim.fadein);
ImageView pearfade = (ImageView) findViewById(R.id.pearish);
pearfadeact.setAnimationListener(new AnimationListener(){
public void onAnimationEnd(Animation animation) {
// The animation has ended, transition to the Main Menu screen
startActivity(new Intent(SplashScreenPear.this, Unicorn.class));
SplashScreenPear.this.finish(); }
public void onAnimationRepeat(Animation animation) {
}
public void onAnimationStart(Animation animation) {
}
});
pearfade.startAnimation(pearfadeact);
}
@Override
protected void onPause() {
super.onPause();
pearfade.clearAnimation();
}
@Override
protected void onResume() {
super.onResume();
startAnimating();
}
}
