您可以为文本视图创建自定义背景。步骤

转到您的项目。转到资源，右键单击可绘制。单击新建->可绘制资源文件为您的文件命名在文件中粘贴以下代码

<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <stroke
        android:width="1dp"
        android:color="@color/colorBlack" />
    <padding
        android:bottom="1dp"
        android:left="1dp"
        android:right="1dp"
        android:top="1dp" />
    <corners android:radius="6dp" />
    <solid android:color="#ffffffff" />
</shape>

对于要将其用作背景的文本视图，android：background=“@drawbable/your_fileName”

我通过扩展文本视图并手动绘制边框解决了这个问题。我甚至添加了这样的选项，您可以选择边框是虚线还是虚线。

public class BorderedTextView extends TextView {
        private Paint paint = new Paint();
        public static final int BORDER_TOP = 0x00000001;
        public static final int BORDER_RIGHT = 0x00000002;
        public static final int BORDER_BOTTOM = 0x00000004;
        public static final int BORDER_LEFT = 0x00000008;

        private Border[] borders;

        public BorderedTextView(Context context, AttributeSet attrs, int defStyle) {
            super(context, attrs, defStyle);
            init();
        }

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

        public BorderedTextView(Context context) {
            super(context);
            init();
        }
        private void init(){
            paint.setStyle(Paint.Style.STROKE);
            paint.setColor(Color.BLACK);
            paint.setStrokeWidth(4);        
        }
        @Override
        protected void onDraw(Canvas canvas) {
            super.onDraw(canvas);
            if(borders == null) return;

            for(Border border : borders){
                paint.setColor(border.getColor());
                paint.setStrokeWidth(border.getWidth());

                if(border.getStyle() == BORDER_TOP){
                    canvas.drawLine(0, 0, getWidth(), 0, paint);                
                } else
                if(border.getStyle() == BORDER_RIGHT){
                    canvas.drawLine(getWidth(), 0, getWidth(), getHeight(), paint);
                } else
                if(border.getStyle() == BORDER_BOTTOM){
                    canvas.drawLine(0, getHeight(), getWidth(), getHeight(), paint);
                } else
                if(border.getStyle() == BORDER_LEFT){
                    canvas.drawLine(0, 0, 0, getHeight(), paint);
                }
            }
        }

        public Border[] getBorders() {
            return borders;
        }

        public void setBorders(Border[] borders) {
            this.borders = borders;
        }
}

边框类：

public class Border {
    private int orientation;
    private int width;
    private int color = Color.BLACK;
    private int style;
    public int getWidth() {
        return width;
    }
    public void setWidth(int width) {
        this.width = width;
    }
    public int getColor() {
        return color;
    }
    public void setColor(int color) {
        this.color = color;
    }
    public int getStyle() {
        return style;
    }
    public void setStyle(int style) {
        this.style = style;
    }
    public int getOrientation() {
        return orientation;
    }
    public void setOrientation(int orientation) {
        this.orientation = orientation;
    }
    public Border(int Style) {
        this.style = Style;
    }
}

希望这对某人有所帮助：）

可以将可绘制的形状（矩形）设置为视图的背景。

<TextView android:text="Some text" android:background="@drawable/back"/>

和矩形drawable back.xml（放入res/drawable文件夹）：

<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle" >
   <solid android:color="@android:color/white" />
   <stroke android:width="1dip" android:color="#4fa5d5"/>
</shape>

您可以使用@android:color/transparent作为纯色，使其具有透明的背景。您还可以使用填充将文本与边框分开。有关详细信息，请参阅：http://developer.android.com/guide/topics/resources/drawable-resource.html

可以通过两种方法设置边框。一种是可绘制的，另一种是编程的。

使用Drawable

<shape>
    <solid android:color="@color/txt_white"/>
    <stroke android:width="1dip" android:color="@color/border_gray"/>
    <corners android:bottomLeftRadius="10dp"
             android:bottomRightRadius="0dp"
             android:topLeftRadius="10dp"
             android:topRightRadius="0dp"/>
    <padding android:bottom="0dip"
             android:left="0dip"
             android:right="0dip"
             android:top="0dip"/>
</shape>

程序化的

public static GradientDrawable backgroundWithoutBorder(int color) {

    GradientDrawable gdDefault = new GradientDrawable();
    gdDefault.setColor(color);
    gdDefault.setCornerRadii(new float[] { radius, radius, 0, 0, 0, 0,
                                           radius, radius });
    return gdDefault;
}

我只是在寻找一个类似的答案——它可以通过Stroke和以下覆盖来完成：

@Override
public void draw(Canvas canvas, MapView mapView, boolean shadow) {

Paint strokePaint = new Paint();
strokePaint.setARGB(255, 0, 0, 0);
strokePaint.setTextAlign(Paint.Align.CENTER);
strokePaint.setTextSize(16);
strokePaint.setTypeface(Typeface.DEFAULT_BOLD);
strokePaint.setStyle(Paint.Style.STROKE);
strokePaint.setStrokeWidth(2);

Paint textPaint = new Paint();
textPaint.setARGB(255, 255, 255, 255);
textPaint.setTextAlign(Paint.Align.CENTER);
textPaint.setTextSize(16);
textPaint.setTypeface(Typeface.DEFAULT_BOLD);

canvas.drawText("Some Text", 100, 100, strokePaint);
canvas.drawText("Some Text", 100, 100, textPaint);

super.draw(canvas, mapView, shadow); 
}

创建一个边框视图，背景颜色作为边框的颜色和文本视图的大小。将边框视图填充设置为边框的宽度。将文本视图背景色设置为文本视图所需的颜色。现在在边框视图中添加文本视图。
