Android java 绘制折线图 纵轴名称为温湿度 横轴名称为时间间隔 坐标轴颜色为#ebf0fc你需要绘制两根折线 每根折线有7个折点 两根线颜色分别为#fd835e#7b79da你需要将折线曲线化使其在视觉上有圆润的感觉

以下是一个简单的绘制折线图的示例代码：

public class LineChartView extends View {
    private static final int PADDING = 100;
    private static final int AXIS_COLOR = Color.parseColor("#ebf0fc");
    private static final int LINE_COLOR_1 = Color.parseColor("#fd835e");
    private static final int LINE_COLOR_2 = Color.parseColor("#7b79da");
    private static final float LINE_WIDTH = 5f;
    private static final float CIRCLE_RADIUS = 10f;

    private float[] data1 = {20.5f, 22.3f, 21.8f, 23.5f, 24.1f, 23.0f, 22.2f};
    private float[] data2 = {40.2f, 42.1f, 41.5f, 43.8f, 44.5f, 43.2f, 42.6f};
    private String[] xLabels = {"1h", "2h", "3h", "4h", "5h", "6h", "7h"};

    private Paint axisPaint;
    private Paint linePaint1;
    private Paint linePaint2;
    private Paint circlePaint1;
    private Paint circlePaint2;
    private Path path1;
    private Path path2;

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

    public LineChartView(Context context, @Nullable AttributeSet attrs) {
        super(context, attrs);
        init();
    }

    public LineChartView(Context context, @Nullable AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        init();
    }

    private void init() {
        axisPaint = new Paint();
        axisPaint.setColor(AXIS_COLOR);
        axisPaint.setStrokeWidth(LINE_WIDTH);
        axisPaint.setStyle(Paint.Style.STROKE);

        linePaint1 = new Paint();
        linePaint1.setColor(LINE_COLOR_1);
        linePaint1.setStrokeWidth(LINE_WIDTH);
        linePaint1.setStyle(Paint.Style.STROKE);

        linePaint2 = new Paint();
        linePaint2.setColor(LINE_COLOR_2);
        linePaint2.setStrokeWidth(LINE_WIDTH);
        linePaint2.setStyle(Paint.Style.STROKE);

        circlePaint1 = new Paint();
        circlePaint1.setColor(LINE_COLOR_1);
        circlePaint1.setStyle(Paint.Style.FILL);

        circlePaint2 = new Paint();
        circlePaint2.setColor(LINE_COLOR_2);
        circlePaint2.setStyle(Paint.Style.FILL);

        path1 = new Path();
        path2 = new Path();
    }

    @Override
    protected void onDraw(Canvas canvas) {
        super.onDraw(canvas);

        int width = getWidth();
        int height = getHeight();

        // 绘制坐标轴
        canvas.drawLine(PADDING, height - PADDING, width - PADDING, height - PADDING, axisPaint);
        canvas.drawLine(PADDING, PADDING, PADDING, height - PADDING, axisPaint);

        // 绘制横轴标签
        float xStep = (width - PADDING * 2) / (xLabels.length - 1);
        for (int i = 0; i < xLabels.length; i++) {
            float x = PADDING + i * xStep;
            canvas.drawText(xLabels[i], x, height - PADDING / 2, axisPaint);
        }

        // 绘制纵轴标签
        canvas.rotate(-90, PADDING / 2, height / 2);
        canvas.drawText("温度", PADDING / 2, height / 2, axisPaint);
        canvas.rotate(90, PADDING / 2, height / 2);
        canvas.drawText("湿度", width - PADDING / 2, height / 2, axisPaint);

        // 绘制折线1
        path1.reset();
        float yStep1 = (height - PADDING * 2) / (data1.length - 1);
        for (int i = 0; i < data1.length; i++) {
            float x = PADDING + i * xStep;
            float y = height - PADDING - data1[i] * yStep1;
            if (i == 0) {
                path1.moveTo(x, y);
            } else {
                path1.lineTo(x, y);
            }
            canvas.drawCircle(x, y, CIRCLE_RADIUS, circlePaint1);
        }
        canvas.drawPath(path1, linePaint1);

        // 绘制折线2
        path2.reset();
        float yStep2 = (height - PADDING * 2) / (data2.length - 1);
        for (int i = 0; i < data2.length; i++) {
            float x = PADDING + i * xStep;
            float y = height - PADDING - data2[i] * yStep2;
            if (i == 0) {
                path2.moveTo(x, y);
            } else {
                path2.lineTo(x, y);
            }
            canvas.drawCircle(x, y, CIRCLE_RADIUS, circlePaint2);
        }
        canvas.drawPath(path2, linePaint2);
    }
}

使用方法：在布局文件中添加LineChartView，或者在代码中创建LineChartView并添加到布局中。

<com.example.linechart.LineChartView
    android:layout_width="match_parent"
    android:layout_height="300dp" />
