在较大的位图上绘制一个小的位图

Question

我想绘制类似这样的东西，但它不显示位图2.只显示位图1（较大的一个）。在ImageView的

imageView1 = (ImageView) findViewById(R.id.imageView1); 
imageView1.setImageBitmap(drawUsingBitmap()); 

//bitmap1 and bitmap2 already initialized 
Bitmap resultBitmap = Bitmap.createBitmap(cubemap.getWidth(), cubemap.getHeight(), cubemap.getConfig()); 
Canvas canvas = new Canvas(resultBitmap); 
canvas.drawBitmap(bitmap1, new Matrix(), null); 
canvas.drawBitmap(bitmap2, (bitmap1.getWidth() - bitmap2.getWidth())/3, (bitmap1.getHeight()) , new Paint()); 
return resultBitmap;

组图像使用位图

public Bitmap drawUsingBitmap() { 
     bitmapLarge = BitmapFactory.decodeResource(getResources(), R.drawable.bitmap_large); 
     bitmapSmall = BitmapFactory.decodeResource(getResources(), R.drawable.bitmap_small); 
     Bitmap resultBitmap = Bitmap.createBitmap(bitmapLarge.getWidth(), bitmapSmall.getHeight() + bitmapLarge.getHeight(), Config.ARGB_8888); 
     Canvas canvas = new Canvas(resultBitmap); 
     // using bitmap 
     Paint paint = new Paint(); 
     paint.setColor(Color.BLACK); 
     canvas.drawBitmap(bitmapSmall, bitmapSmall.getWidth()/2, 0, paint); 
     canvas.drawBitmap(bitmapLarge, 0, bitmapSmall.getHeight() - 10, paint); 
     return resultBitmap; 
    } 

使用的drawRect

public Bitmap draWUsingRect() { 
     // using rectangle 
     int widthSmall = 120; 
     int heightSmall = 80; 
     int widthLarge = 400; 
     int heightLarge = 300; 
     Bitmap resultBitmap = Bitmap.createBitmap(widthLarge + 20, heightSmall + heightLarge + 20, Config.ARGB_8888); 
     Canvas canvas = new Canvas(resultBitmap); 
     Paint paint = new Paint(); 
     paint.setColor(Color.BLACK); 
     paint.setStyle(Style.STROKE); 
     paint.setStrokeWidth(5); 
     canvas.drawRect(new Rect(widthSmall/2, 0, widthSmall, heightSmall), paint); 
     canvas.drawRect(new Rect(0, heightSmall, widthLarge, heightSmall + heightLarge), paint); 
     return resultBitmap; 
    } 

我希望这对你有帮助。
