Use Canvas's drawTextOnPath method to draw text along the Path

Android's Canvas provides a drawTextOnPath(String text, Path path, float hOffset, float vOffset, Paint paint) method, which can draw text along the Path path, where text refers to the text content, the hOffset parameter specifies the horizontal offset, and the vOffset specifies the Vertical offset, the following is a simple example to demonstrate, the code is as follows:

Activity：

package com.lovo.testcanvasactivity;

import android.app.Activity;
import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.graphics.Path;
import android.graphics.RectF;
import android.os.Bundle;
import android.view.View;

public class TestPathActivity extends Activity {

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate (savedInstanceState);
		setContentView(new MyView(this));
	}

	class MyView extends View {
		final String DRAW_STR = "Tianxingjian, the gentleman strives for self-improvement";
		// brush
		private Paint paint;
		// declare an array of path objects
		Path[] paths = new Path[3];

		public MyView(Context context) {
			super(context);
			paths[0] = new Path();
			paths[0].moveTo(0, 0);
			for (int i = 0; i <= 7; i++) {
				// Generate 7 points, randomly generate Y coordinates, and connect them into a line
				paths[0].lineTo(i * 30, (float) Math.random() * 30);
			}
			paths[1] = new Path();
			RectF rectF = new RectF(0, 0, 200, 120);
			paths[1].addOval(rectF, Path.Direction.CCW);
			paths[2] = new Path();
			paths[2].addArc(rectF, 60, 180);
			// initialize the brush
			paint = new Paint();
			paint.setAntiAlias(true);
			paint.setColor(Color.CYAN);
			paint.setStrokeWidth(1);
		}

		@Override
		protected void onDraw(Canvas canvas) {
			// fill the background with white
			canvas.drawColor(Color.WHITE);
			canvas.translate(40, 40);
			// Set to start drawing from the right (right-aligned)
			paint.setTextAlign(Paint.Align.RIGHT);
			paint.setTextSize(20);

			// draw the path
			paint.setStyle(Paint.Style.STROKE);
			canvas.drawPath(paths[0], paint);
			// draw a piece of text along the path
			paint.setStyle(Paint.Style.FILL);
			canvas.drawTextOnPath(DRAW_STR, paths[0], -8, 20, paint);

			// Move the canvas down 120
			canvas.translate(0, 120);

			// draw the path
			paint.setStyle(Paint.Style.STROKE);
			canvas.drawPath(paths[1], paint);
			// draw a piece of text along the path
			paint.setStyle(Paint.Style.FILL);
			canvas.drawTextOnPath(DRAW_STR, paths[1], -20, 20, paint);

			// Move the canvas down 120
			canvas.translate(0, 120);

			// draw the path
			paint.setStyle(Paint.Style.STROKE);
			canvas.drawPath(paths[2], paint);
			// draw a piece of text along the path
			paint.setStyle(Paint.Style.FILL);
			canvas.drawTextOnPath(DRAW_STR, paths[2], -10, 20, paint);
		}
	}
}
