Question

我想知道为什么scrollView想要显示的原因。我从互联网上下载了一些图像，然后在ImageView中将其设置为Drawable但没有任何反应。当图片很小时一切正常。错误在哪里？

Funkction我填充了View：

public void setUpLayout()
    {

        DisplayMetrics displaymetrics = new DisplayMetrics();
        getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
        int height = displaymetrics.heightPixels;
        int width = displaymetrics.widthPixels;
        heightOfScreen = height;

        heighOfImage = image.getHeight();

        System.out.println("Screen" +height);
        System.out.println("IMAGE" + heighOfImage);

        if(heighOfImage < height)
        {
            imageViewSmall.setImageBitmap(image);
            imageViewSmall.setVisibility(View.VISIBLE);

            scrollViewImage.setEnabled(false);
        }
        else
        {

            scrollViewImage.setVisibility(View.VISIBLE);
            imageViewBig.setImageBitmap(image);
            //imageViewBig.setVisibility(View.VISIBLE);
            scrollViewImage.setEnabled(false);
        }
    }

包含所有内容的XML文件查看：

<RelativeLayout

    android:layout_width="fill_parent"

    <TextView 
        android:layout_height="20dp"
        android:layout_width="fill_parent"

        android:text="dadasadsadsasddassdsdsdsadasdd"/>

    <com.polites.android.GestureImageView

        android:id="@+id/scrollViewImage"
        android:scrollbars="none"
        android:visibility="gone">


       <com.polites.android.GestureImageView
            android:id="@+id/imageBig"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"

            gesture-image:max-scale="10.0"
            gesture-image:min-scale="0.0"
            gesture-image:strict="false" />

    </ScrollView>

   <ProgressBar
       android:id="@+id/imageProgressBar"
       style="?android:attr/progressBarStyleLarge"
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:layout_centerHorizontal="true"
       android:layout_centerVertical="true"

       />

</RelativeLayout>
