android - 需要使用此边框创建此图像视图

Question

嗨，我需要用这个边框制作这个图像视图

带有此边框的多边形图像视图：

我用这个自定义的六边形蒙版图像视图创建了这种类型的图像视图。

public class HexagonMaskView extends android.support.v7.widget.AppCompatImageView {
private Path hexagonPath;
private Path hexagonBorderPath;
private Paint mBorderPaint,mEdgesPaint;
float radiusX;

public HexagonMaskView(Context context) {
    super(context);
    init();
}

public HexagonMaskView(Context context, AttributeSet attrs) {
    super(context, attrs);
    init();
}

public HexagonMaskView(Context context, AttributeSet attrs, int defStyleAttr) {
    super(context, attrs, defStyleAttr);
    init();
}

private void init() {
    this.hexagonPath = new Path();
    this.hexagonBorderPath = new Path();

    this.mBorderPaint = new Paint();
    this.mBorderPaint.setColor(getResources().getColor(R.color.colorAccent));
    this.mBorderPaint.setStrokeCap(Paint.Cap.ROUND);
    this.mBorderPaint.setStrokeWidth(40f);
    this.mBorderPaint.setStyle(Paint.Style.STROKE);

    this.mEdgesPaint = new Paint();
    this.mEdgesPaint.setColor(getResources().getColor(R.color.colorAccent));
    this.mEdgesPaint.setStrokeCap(Paint.Cap.ROUND);
    this.mEdgesPaint.setStrokeWidth(15f);
    this.mEdgesPaint.setStyle(Paint.Style.STROKE);
}

private void calculatePath(float radius) {
    radiusX = radius;

    mBorderPaint.setStrokeWidth(radius/3);
    mEdgesPaint.setStrokeWidth(radius/6);

    float halfRadius = radius / 2f;
    float triangleHeight = (float) (Math.sqrt(3.0) * halfRadius);
    float centerX = getMeasuredWidth() / 2f;
    float centerY = getMeasuredHeight() / 2f;

    this.hexagonPath.reset();
    this.hexagonPath.moveTo(centerX, centerY + radius);
    this.hexagonPath.lineTo(centerX - triangleHeight, centerY + halfRadius);
    this.hexagonPath.lineTo(centerX - triangleHeight, centerY - halfRadius);
    this.hexagonPath.lineTo(centerX, centerY - radius);
    this.hexagonPath.lineTo(centerX + triangleHeight, centerY - halfRadius);
    this.hexagonPath.lineTo(centerX + triangleHeight, centerY + halfRadius);
    this.hexagonPath.close();

    float radiusBorder = radius - 5f;
    float halfRadiusBorder = radiusBorder / 2f;
    float triangleBorderHeight = (float) (Math.sqrt(3.0) * halfRadiusBorder);

    this.hexagonBorderPath.reset();
    this.hexagonBorderPath.moveTo(centerX, centerY + radiusBorder);
    this.hexagonBorderPath.lineTo(centerX - triangleBorderHeight, centerY + halfRadiusBorder);
    this.hexagonBorderPath.lineTo(centerX - triangleBorderHeight, centerY - halfRadiusBorder);
    this.hexagonBorderPath.lineTo(centerX, centerY - radiusBorder);
    this.hexagonBorderPath.lineTo(centerX + triangleBorderHeight, centerY - halfRadiusBorder);
    this.hexagonBorderPath.lineTo(centerX + triangleBorderHeight, centerY + halfRadiusBorder);
    this.hexagonBorderPath.close();

    invalidate();
}


@Override
public void onDraw(Canvas c) {

    float halfRadiusBorder = radiusX / 2f;
    float radiusBorder = radiusX - 5f;
    float triangleBorderHeight = (float) (Math.sqrt(3.0) * halfRadiusBorder);
    float centerX = getMeasuredWidth() / 2f;
    float centerY = getMeasuredHeight() / 2f;

    c.clipPath(hexagonPath, Region.Op.INTERSECT);
    c.drawColor(Color.TRANSPARENT, PorterDuff.Mode.CLEAR);

    super.onDraw(c);
}

@Override
public void onMeasure(int widthMeasureSpec, int heightMeasureSpec){
    super.onMeasure(widthMeasureSpec, heightMeasureSpec);
    int width = MeasureSpec.getSize(widthMeasureSpec);
    int height = MeasureSpec.getSize(heightMeasureSpec);
    setMeasuredDimension(width, height);
    calculatePath(Math.min(width / 2f, height / 2f) - 10f);
}

这段代码制作了一个自定义图像视图，其形状与我想要的完全一样，但问题是我无法正确应用边框，因为屏幕尺寸会更改边框如果应用为图像叠加层有尺寸问题，因为它不是直接应用于图像视图

这就是我使用相对布局来制作我想要的东西的方式

<RelativeLayout
                    android:id="@+id/frameCont"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content">

                    <com.dev.mytechnology.hellostream.Helper.HexagonMaskView
                        android:id="@+id/image"
                        android:layout_width="@dimen/_43sdp"
                        android:layout_height="@dimen/_43sdp"
                        android:src="@drawable/sample_face_1_dummy"
                        android:layout_centerInParent="true"
                        android:background="@android:color/transparent"/>

                    <ImageView
                        android:id="@+id/frame"
                        android:layout_width="@dimen/_45sdp"
                        android:layout_height="@dimen/_45sdp"
                        android:layout_centerInParent="true"
                        android:src="@drawable/hs_hexa_frame_white" />
                </RelativeLayout>

这是生成的用户界面：

我知道我没有使用最佳方式，但请让我知道如何在我的六边形图像视图上应用这样的边框，或者任何其他选项也将不胜感激。
