這是相當難用XML標記來實現你的UI，但也有Canvas方法，其輕鬆畫出所有的圖元。

樣品：

private Paint circlePaint; 
private Paint linePaint; 
private Paint textPaint; 
private String[] titles; 
private float circleRadius; 

@Override protected void onDraw(Canvas canvas) { 

    float height = getHeight(); 
    float width = getWidth(); 
    float circleX;//set initial X depending on width and height of screen 
    float circleY;//set initial Y 

    for (int i = 0; i < titles.length; i++) { 
     String title = titles[i]; 
     canvas.drawCircle(circleX, circleY, circleRadius, circlePaint); 
     canvas.drawText(title, circleX + circleRadius, circleY, textPaint); 

     float nextCircleX;//calculate next X coordinate 
     float nextCircleY;//calculate next Y coordinate 

     canvas.drawLine(circleX, circleY, nextCircleX, nextCircleY, circlePaint); 

     circleX = nextCircleX; 
     circleY = nextCircleY; 
    } 
}
