Question

我有一个闪屏，显示图像2秒。图像是PNG图像。当我启动我的APP时，它会崩溃并出现以下错误消息。我的应用程序崩溃的确切行是setContentView（R.layout.splash）;

关键错误行：我可以看到在膨胀布局时引用java.lang.OutOfMemoryError时出现了一些错误

请告诉我在哪里需要更正我的代码。

XML

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout  
xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="fill_parent"  
android:layout_height="fill_parent" 
android:background="@drawable/splash">  

</RelativeLayout>

Java代码：

 public class Splash extends Activity{
@Override
protected void onCreate(Bundle GoOnSudha) {
    // TODO Auto-generated method stub
    super.onCreate(GoOnSudha);

    requestWindowFeature(Window.FEATURE_NO_TITLE);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
    setContentView(R.layout.splash);

    Thread thread = new Thread(){
        public void run(){
            try{
                sleep(2000);
            } catch (InterruptedException e){
                e.printStackTrace();
            }finally{
                Intent dragDropIntent = new Intent("android.intent.action.DRAGDROP");
                startActivity(dragDropIntent);
            }
        }
    };
    thread.start();
}

@Override
protected void onPause() {
    // TODO Auto-generated method stub
    super.onPause();
    finish();
}

}

Answer 1

您的图片尺寸太大。您的app超出了为您的应用分配的堆大小。因此，您将获得OutofMemoryException。堆大小因设备而异。

缩小位图或使用占用更少内存的其他图像。

您需要有效地加载位图。查看在内存中加载缩小版本的主题。

还可以在onResume（）中将drawable加载到布局中，并在onPause（）中解除布局中的drawable绑定。

Answer 2

2.5 mb太大而无法显示几秒钟。如果它是位图文件，请尝试更改为更加压缩的格式，因为它们很大并占用大量内存，例如Android所说的图像here

Bitmaps会占用大量内存，尤其是对于像照片这样的丰富图像。例如，Galaxy Nexus上的相机拍摄的照片最高可达2592x1936像素（5百万像素）。如果使用的位图配置是ARGB_8888（默认情况下从Android 2.3开始），那么将此图像加载到内存中需要大约19MB的内存（2592 * 1936 * 4字节），立即耗尽某些设备上的每个应用程序限制。
