我尝试在启动活动中使用动画，但动画启动和运行意图（启动新活动）应用程序崩溃。
看我的Splash活动：
package com.skyline.paranorman;
import android.os.Bundle;
import android.os.Handler;
import android.app.Activity;
import android.content.Intent;
import android.graphics.drawable.AnimationDrawable;
import android.view.Menu;
import android.widget.ImageView;
public class Splash extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash);
final ImageView img = (ImageView) findViewById(R.id.imageView1);
img.setBackgroundResource(R.anim.animation);
img.setImageDrawable(null);
AnimationDrawable anim = (AnimationDrawable) img.getBackground();
anim.start();
Thread background = new Thread() {
public void run() {
try {
sleep(5*1000);
} catch (Exception e) {
e.printStackTrace();
}finally{
// After 5 seconds redirect to another intent
Intent i=new Intent(getBaseContext(),MainActivity.class);
startActivity(i);
//Remove activity
finish();
}
}
};
// start thread
background.start();
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.splash, menu);
return true;
}
}

更新： 当我从启动活动中删除动画时，通常会启动它！
