我有什么？
Main activity - 有 7 个按钮，每个按钮都有一个图像作为背景。所有按钮都是可点击的，点击每个按钮都会启动一个新的 activity。因此，如果我单击按钮 1，则会启动 activity1，单击按钮 2 时，会启动 activity2，依此类推。每个新活动，即 activity1、activity2、... activity7 也有一个图像，应用程序从 mipmap 文件夹中获取该图像。

我的问题是什么？
我有内存过剩的错误。
我的问题的图形表示
请看下图：
有人可以帮助我吗？有没有更好的方法来解决这个问题？
任何帮助将不胜感激。谢谢！
1) 确保您的图像尺寸最适合它们将在其上显示的最高密度。 （如果它们是正在压缩的巨大图像，它们会占用大量额外内存）。
2) 将所有按钮更改为 ImageButtons，然后在 activity onStop():
之后清除内存
@Override
protected void onStop(){
// This controls the images and makes sure
// they're not using memory once the activity is closed
Drawable d = imageButton1.getDrawable();
if (d != null) d.setCallback(null);
imageButton1.setImageDrawable(null);
}
请记住，当您想要重新加载 activity 时，您必须重新声明您的 imageButton src。
@Override
protected void onResume(){
super.onResume();
imageButton1.setImageResource(R.mipmap.pic_small_inside);
}
我想我已经能够解决我的主要问题 - 感谢大家的帮助 但是，我在 logcat 中收到以下警告/错误消息：

我有什么？ Main activity - 有 7 个按钮，每个按钮都有一个图像作为背景。所有按钮都是可点击的，点击每个按钮都会启动一个新的 activity。因此，如果我单击按钮 1，则会启动 activity1，单击按钮 2 时，会启动 activity2，依此类推。每个新活动，即 activity1、activity2、... activity7 也有一个图像，应用程序从 mipmap 文件夹中获取该图像。

我的问题是什么？ 我有内存过剩的错误。
我的问题的图形表示
请看下图：
有人可以帮助我吗？有没有更好的方法来解决这个问题？
任何帮助将不胜感激。谢谢！
1) 确保您的图像尺寸最适合它们将在其上显示的最高密度。 （如果它们是正在压缩的巨大图像，它们会占用大量额外内存）。
2) 将所有按钮更改为 ImageButtons，然后在 activity onStop():
@Override
protected void onStop(){
// This controls the images and makes sure
// they're not using memory once the activity is closed
Drawable d = imageButton1.getDrawable();
if (d != null) d.setCallback(null);
imageButton1.setImageDrawable(null);
}
请记住，当您想要重新加载 activity 时，您必须重新声明您的 imageButton src。
@Override
protected void onResume(){
super.onResume();
imageButton1.setImageResource(R.mipmap.pic_small_inside);
}
