插入图像时，imageView外部的虚线不适合

Question

我有一个表单，您可以在其中插入图像。我在虚拟内部的/* Compute q = (a - K) / (a + K) with improved accuracy. Variant 5 */ m = a - K; p = a + K; r = 1.0f / p; q = m * r; t = fmaf (q + 1.0f, -K, a); e = fmaf (q, -a, t); q = fmaf (r, e, q); 外面放了虚线。我还使用了一个图像适合imageview的类。现在，当我尝试在imageview中插入图像时，它可以成功插入图像，但虚线不会根据图像的大小进行调整。

imageview

class of image to fit inside the imageView

public class SquareImageView extends ImageView { public SquareImageView(Context context) { super(context); } public SquareImageView(Context context, AttributeSet attrs) { super(context, attrs); } public SquareImageView(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); } @Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { super.onMeasure(widthMeasureSpec, heightMeasureSpec); setMeasuredDimension(getMeasuredWidth(), getMeasuredWidth()); //Snap to width } }

XML file for the stroke

<shape xmlns:android="http://schemas.android.com/apk/res/android"> <stroke android:width="2dp" android:color="#cccccc" android:dashWidth="10dp" android:dashGap="6dp" /> <padding android:left="7dp" android:top="7dp" android:right="7dp" android:bottom="7dp" /> <corners android:radius="2dp" /> </shape> 用于图片视图

content_main.xml

<junienegentien2015.android.ourthesis.com.detailsform.SquareImageView android:id="@+id/container_with_dotted_border" android:layout_width="fill_parent" android:layout_height="wrap_content" android:scaleType="centerCrop" android:background="@drawable/dotted_border" android:src="@drawable/grm_upload"/>
