Android : java.lang.OutOfMemoryError:
2022-09-04 19:38:18
我开发了一个在Android上使用大量图像的应用程序。
在可绘制的文件夹中有很多图像,说超过100个,我正在开发用于图像动画的应用程序。我使用图像视图来显示GIF图像。我已经使用了将gif图像拆分为多个PNG格式图像的概念,然后使用它。
每次用户进入应用程序时,我都可以看到内存越来越大,直到用户获得.java.lang.OutOfMemoryError
那么处理许多图像的最佳/正确方法是什么?
以下是我的代码:
dog_animation.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/DogView"
android:orientation="vertical" >
<ImageView
android:id="@+id/dog_animation"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="0.19" />
dog_animation.xml(可绘制文件夹)

Dog_Animation.java
public class Dog_Animation extends Activity {
Timer timer = new Timer();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.dog_animation);
ImageView img = (ImageView) findViewById(R.id.dog_animation);
img.setBackgroundResource(R.drawable.dog_animation);
AnimationDrawable frameAnimation = (AnimationDrawable) img
.getBackground();
frameAnimation.start();
timer.schedule(new TimerTask() {
public void run() {
Intent intent = new Intent(Dog_Animation.this,
Man_Animation.class);
startActivity(intent);
}
}, 10000);
}
}
现在的问题是,当我尝试从一个活动移动到另一个具有相同其他图像的活动以进行动画处理时,它会给我错误。java.lang.OutOfMemory
我尝试过很多不同的解决方案,例如
@Override
protected void onDestroy() {
super.onDestroy();
unbindDrawables(findViewById(R.id.DogView));
System.gc();
}
private void unbindDrawables(View view) {
if (view.getBackground() != null) {
view.getBackground().setCallback(null);
}
if (view instanceof ViewGroup) {
for (int i = 0; i < ((ViewGroup) view).getChildCount(); i++) {
unbindDrawables(((ViewGroup) view).getChildAt(i));
}
((ViewGroup) view).removeAllViews();
}
}
所以其他的,但任何解决方案都不适合我。请帮我解决这个问题。即使我已经参考了 http://androidactivity.wordpress.com/2011/09/24/solution-for-outofmemoryerror-bitmap-size-exceeds-vm-budget/ 这个链接,但没有解决问题。
