我有新的要求，使用android canvas.now在橢圓內繪製橢圓，但沒有繪製橢圓內的文本添加下面給出的參考。

Answer 1

爲（）分辨率（480×800）

中的onCreate

setContentView(new SampleView(this)); 

創建類

private static class SampleView extends View { 

    // CONSTRUCTOR 
    public SampleView(Context context) { 
     super(context); 
     setFocusable(true); 

    } 

    @SuppressLint("DrawAllocation") 
    @Override 
    protected void onDraw(Canvas canvas) { 

     canvas.drawColor(Color.WHITE); 

     //1 
     Paint paint = new Paint(); 
     paint.setStyle(Paint.Style.STROKE); 
     paint.setColor(Color.GRAY); 
     RectF oval1 = new RectF(0, 0, 250,250); 

     Paint p1 = new Paint(); 
     p1.setColor(Color.BLACK); 

     canvas.drawText("Parent", 30, 50, p1); 
     canvas.drawOval(oval1, paint); 


     //2 
     paint.setStyle(Paint.Style.STROKE); 
     paint.setColor(Color.BLUE); 
     RectF oval2 = new RectF(50, 50, 150, 150); 

     Paint p2 = new Paint(); 
     p2.setColor(Color.GREEN); 

     canvas.drawText("Child", 75, 75, p2); 
     canvas.drawOval(oval2, paint); 
    } 

}
