android - 位图太大而无法上传到纹理中(5312x2988，最大 = 4096x4096)- 如何解决此问题？

Question

这是我开始的教程。

http://www.androidhive.info/2014/12/android-uploading-camera-image-video-to-server-with-progress-bar/

基本上，我已经上传了一张图片，我想在自定义图片查看器中显示它。

我已经像这样调整了我的 php.ini 以接受大量上传。

memory_limit = 128M
post_max_size = 1G 
file_uploads = On
upload_max_filesize = 1G
max_file_uploads = 20 

这是我从 logcat 得到的错误

03-15 01:06:36.843: W/OpenGLRenderer(14403): 位图太大无法上传到纹理中 (5312x2988, max=4096x4096)

好的，所以问题是，当我尝试显示 6M、8M、9M 或 12MEGAPIXELS 的图片时，一切正常。当我尝试显示一张 16Megapixels 照片时，它不显示。

好的，但是教程中的图像查看器会显示图像。但我正在使用不同的类来显示图像。图像查看器似乎显示来自您的 SdCard 的图像。 FeedImageView 允许您显示保存在服务器上的图片。

public class FeedImageView extends ImageView {

    public interface ResponseObserver {
        public void onError();

        public void onSuccess();
    }

        mObserver = observer;
    }

     * image is loaded.

        this(context, null);

    }

    public FeedImageView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);

如何让图片像常规的那样在 FeedImageView 类中以 16 百万像素显示

private ImageView imgPreview; 

教程使用的类？

Answer 1

设置

android:hardwareAccelerated="false"

&

android:largeHeap="true"

在 list 文件的应用程序标签内。

目前看来这可以正常工作。当我使用这些参数设置滚动图片时，动画有点断断续续。

<application
    android:name="com.clxxxii.givenchy"
    android:allowBackup="true"
    android:hardwareAccelerated="false"
    android:icon="@drawable/givenchy"
    android:label="@string/app_name"
    android:largeHeap="true"
    android:theme="@style/CustomActionBarTheme" >
