请帮助..
我的应用程序在动画开始播放时提供了一个outofmemory异常..我该怎么办？ 动画组合中的图像大小为512kb，即10幅图像。
我的活动课程是button_anime
public class Button_Anime extends Activity{
private static int SPLASH_TIME_OUT = 500;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash_about);
ImageView loading =(ImageView) findViewById(R.id.iVArcRail_2);
loading.setBackgroundResource(R.drawable.about_button_anime);
AnimationDrawable load =(AnimationDrawable)loading.getBackground();
load.start();
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
Intent i = new Intent(Button_Anime.this, Home.class);
startActivity(i);
finish();
}
}, SPLASH_TIME_OUT);
}
}
my activity_splash_about.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/withoutlogo" >
<ImageView
android:id="@+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="70dp"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginBottom="10dp"
android:layout_marginTop="10dp"
android:background="@drawable/logoline" />
<ImageView
android:id="@+id/iVArcRail_2"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="@+id/imageView1"/>
</RelativeLayout>
这是动画文件.. about_button_anime
<?xml version="1.0" encoding="utf-8"?>
<animation-list xmlns:android="http://schemas.android.com/apk/res/android"
android:oneshot="false" >
<item

我怎么能让这个动画运行???请帮忙......在这里绝望......
抱歉没有提前发布..

这就像魅力一样，
确保将图像放在资产文件夹中。
public class AnimationActivily extends Activity {
private Bitmap log_imgs[];
private Bitmap tempBitmap;
private Handler uiHandler;
private ImageView logo_view;
int img_cnt = 1;
protected int _splashTime = 91;
Thread splashTread;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_animation_activily);
logo_view = (ImageView) findViewById(R.id.logo_view);
log_imgs = new Bitmap[91];
for (int i = 1; i <= 90; i++) {
get_Images_Assest(i, "logo_pngs");
}
logo_view.setImageBitmap(log_imgs[70]);
uiHandler = new Handler();
// thread for displaying the SplashScreen
splashTread = new Thread() {
@Override
public void run() {
try {
while (img_cnt < _splashTime) {
sleep(30);
if (img_cnt <= 90)
update_view(img_cnt);
img_cnt++;
}
} catch (InterruptedException e) {
// do nothing
} finally {
Intent i = new Intent(AnimationActivily.this,
MainActivity.class);
i.setFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
startActivity(i);
AnimationActivily.this.finish();
// overridePendingTransition(R.anim.slide_in,
// R.anim.slide_out);
// *** Put this in another
// Activity***//overridePendingTransition(R.anim.slide_in,
// R.anim.slide_out);
}
}
};
splashTread.start();
}
public Bitmap tempImg;
private void get_Images_Assest(int cnt, String folder_name) {
try {
InputStream is = getAssets().open(
folder_name + "/" + "logo" + cnt + ".png");
if (tempImg != null) {
tempImg = null;
}
tempImg = BitmapFactory.decodeStream(is);
// tempBitmap = Bitmap.createScaledBitmap(tempImg,
// tempImg.getWidth() * 2, tempImg.getHeight() * 2, true);
log_imgs[cnt] = tempImg;
} catch (IOException e) {
e.printStackTrace();
}
}
public void update_view(final int cnt) {
uiHandler.post(new Runnable() {
public void run() {
try {
logo_view.setImageBitmap(log_imgs[cnt]);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
public void onBackPressed() {
}
public void onDestroy() {
super.onDestroy();
for (int i = 1; i <= 90; i++) {
log_imgs[i].recycle();
}
log_imgs = null;
splashTread = null;
}
}

我遇到了同样的问题，所以我创建了一个避免OutOfMemoryError的类。 Android一次加载所有drawable，因此具有多个帧的动画会导致此错误。
FasterAnimationsContainer将帮助您避免OutOfMemoryError。这门课加载＆amp;在后台线程上设置和发布图像。
这里是link
public class ExampleActivity extends Activity {
FasterAnimationsContainer mFasterAnimationsContainer;
private static final int[] IMAGE_RESOURCES = { R.drawable.anim_1,
R.drawable.anim_2, R.drawable.anim_3, R.drawable.anim_4,
R.drawable.anim_5, R.drawable.anim_6, R.drawable.anim_7,
R.drawable.anim_8 };
private static final int ANIMATION_INTERVAL = 500;// 200ms
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_example);
ImageView imageView = (ImageView) findViewById(R.id.imageview);
mFasterAnimationsContainer = FasterAnimationsContainer
.getInstance(imageView);
mFasterAnimationsContainer.addAllFrames(IMAGE_RESOURCES,
ANIMATION_INTERVAL);
mFasterAnimationsContainer.start();
}
@Override
protected void onDestroy() {
super.onDestroy();
mFasterAnimationsContainer.stop();
}
}

我在内存不足的设备上遇到类似的背景动画问题。 我设法修复它的方法是通过编程方式而不是通过xml动画列表实例化动画。我不再遇到这种观点的内存不足问题。
AnimationDrawable animationDrawable = new AnimationDrawable();
animationDrawable.setOneShot(false); // True = only once, False = continuous
int[] resources = {R.drawable.ticket_background_animation_1, R.drawable.ticket_background_animation_2, R.drawable.ticket_background_animation_3};
int duration = 30;
for (int resource : resources) {
animationDrawable.addFrame(ContextCompat.getDrawable(context, resource), duration);
}
relativeLayout.setBackground(animationDrawable);
animationDrawable.start();
当然，记住在 onDestroy（）中再次停止动画也很重要！
((AnimationDrawable) relativeLayout.getBackground()).stop();
// Sets background to null to make sure the animation is garbage collected
relativeLayout.setBackground(null);
