Question

我正在编写Android应用，但它崩溃了。这是代码：

public class Images extends Activity {

    private ImageView d1;
    private ArrayList<Integer> listaImagenes=new ArrayList<Integer>();
     @Override
     public void onCreate (Bundle savedInstanceState)
     {
         super.onCreate(savedInstanceState);
         this.rellenar();
          setContentView(R.layout.imagentonas);
          d1=(ImageView)findViewById(R.id.imagenes01);
          d1.setImageResource(listaImagenes.get(0));

     }
     private void rellenar()
     {
        listaImagenes.add(R.drawable.rosa1); 
        listaImagenes.add(R.drawable.imagencilla); 
     }
}

logcat的：

如果我将listaImagenes.get(0)更改为listaImagenes.get(1)，则该应用会崩溃。我不知道为什么会这样......

Answer 1

所以，既然你得到OutOfMemoryError，我猜它会与你尝试加载的资源的大小有关。我会说rosa1 drawable可能很大，而imagencilla drawable可能较小。这可以解释为什么您在尝试加载imagencilla时不会崩溃，但在尝试加载rosa1时会崩溃。

您应该验证APK中包含的rosa1 drawable的大小，并尽可能缩小它。如果缩小它是不可能的，您可能必须提出一种自定义方法来加载不会尝试将其全部解码到内存中的资源。

ImageView和ArrayList
