如何在Android中创建一个一侧倾斜的矩形？

import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Paint;
import android.graphics.Path;
import android.util.AttributeSet;
import android.view.View;

public class SlantedRectangleView extends View {
    private Paint paint;
    private Path path;

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

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

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

    private void init() {
        paint = new Paint();
        paint.setColor(getResources().getColor(android.R.color.holo_blue_light));
        paint.setStyle(Paint.Style.FILL);
        paint.setAntiAlias(true);

        path = new Path();
    }

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

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

        path.reset();
        path.moveTo(0, 0);
        path.lineTo(width, 0);
        path.lineTo(width, height);
        path.lineTo(0, height - height / 4); // 控制倾斜程度
        path.close();

        canvas.drawPath(path, paint);
    }
}

<com.example.SlantedRectangleView
    android:layout_width="match_parent"
    android:layout_height="200dp" />
