Question

我想以编程方式在ImageView上设置图像，但是当我尝试放一个jpg文件时，我收到一个错误。这是我的代码：

VideoView videoview;
    ImageView immagine;
    Button button;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        button = (Button) findViewById(R.id.button);
        immagine = (ImageView) findViewById(R.id.imageView2);

        immagine.setImageResource(R.drawable.aresbkg);

这就是逻辑：

我该如何解决这个问题？这不是我第一次使用ImageView，因此我不知道为什么在这种情况下我会收到此错误。在我的其他应用程序中一切正常。非常感谢。洛伦佐

Answer 1

使用此library来避免OOM。

Answer 2

一个很好的旧OutOfMemory：无论如何，我认为2.5 MB对于在Android设备上展示来说太大了。

也许您可以使用像毕加索（http://square.github.io/picasso/）这样的库来调整图像大小？（就像@Devit 951首先提出的那样）

内存不足错误imageview
