如何在Android中实现图像下方的垂直虚线？

我如何在不使用任何库的情况下实现这种布局

我尝试了类似的方法，但无法得到确切的布局

这是我使用上面实现的代码得到的结果。如何得到像我上面发布的图片一样的结果

我甚至尝试过约束布局，但也没有帮助

1.创建包含以下内容的文件“/res/values/attrs.xml”：

<?xml version="1.0" encoding="utf-8"?>
<resources>

<declare-styleable name="DividerView">
    <attr name="color" format="color" />
    <attr name="dashLength" format="dimension" />
    <attr name="dashGap" format="dimension" />
    <attr name="dashThickness" format="dimension" />
    <attr name="orientation" format="enum">
        <enum name="horizontal" value="0" />
        <enum name="vertical" value="1" />
    </attr>
</declare-styleable>

</resources>

public class DividerView extends View {
static public int ORIENTATION_HORIZONTAL = 0;
static public int ORIENTATION_VERTICAL = 1;
private Paint mPaint;
private int orientation;

public DividerView(Context context, AttributeSet attrs) {
    super(context, attrs);
    int dashGap, dashLength, dashThickness;
    int color;

    TypedArray a = context.getTheme().obtainStyledAttributes(attrs, R.styleable.DividerView, 0, 0);

    try {
        dashGap = a.getDimensionPixelSize(R.styleable.DividerView_dashGap, 5);
        dashLength = a.getDimensionPixelSize(R.styleable.DividerView_dashLength, 5);
        dashThickness = a.getDimensionPixelSize(R.styleable.DividerView_dashThickness, 3);
        color = a.getColor(R.styleable.DividerView_color, 0xff000000);
        orientation = a.getInt(R.styleable.DividerView_orientation, ORIENTATION_HORIZONTAL);
    } finally {
        a.recycle();
    }

    mPaint = new Paint();
    mPaint.setAntiAlias(true);
    mPaint.setColor(color);
    mPaint.setStyle(Paint.Style.STROKE);
    mPaint.setStrokeWidth(dashThickness);
    mPaint.setPathEffect(new DashPathEffect(new float[] { dashLength, dashGap, }, 0));
}

public DividerView(Context context) {
    this(context, null);
}

@Override
protected void onDraw(Canvas canvas) {
    if (orientation == ORIENTATION_HORIZONTAL) {
        float center = getHeight() * .5f; 
        canvas.drawLine(0, center, getWidth(), center, mPaint);
    } else {
        float center = getWidth() * .5f; 
        canvas.drawLine(center, 0, center, getHeight(), mPaint);
    }
}
}

希望这对所有人都有效。

另一种实现虚线的方法

android中使用形状的水平和垂直虚线

<rotate xmlns:android="http://schemas.android.com/apk/res/android"
    android:fromDegrees="90"
    android:toDegrees="90" >

    <shape android:shape="line" >
        <stroke
            android:dashGap="6px"
            android:dashWidth="6px"
            android:color="#C7B299" />
    </shape>

</rotate>
