使用代码把两个图像结合起来

Question

我使用下面的代码把两个图像结合起来。

 Bitmap pic = BitmapFactory.decodeResource(getResources(), R.drawable.me);
    Bitmap map = BitmapFactory.decodeResource(getResources(), R.drawable.static);
    Canvas comboImage = new Canvas(map);
    Bitmap out1 = null ;
    comboImage.setBitmap(out1);
    comboImage.drawBitmap(pic, 600, 350, null);

假定我可以使用 bitmap out1 获取最后的图像，但是 comboImage.setBitmap(out1); 这一行引发崩溃。没有这一行不能看到任何图像。如何获取最后结合图像？

Answer 1

Bitmap pic = BitmapFactory.decodeResource(getResources(), R.drawable.me);
Bitmap map = BitmapFactory.decodeResource(getResources(), R.drawable.static);

 **Bitmap out1 = Bitmap.createBitmap(width, height, Config.ARGB_8888);;
Canvas comboImage = new Canvas(out1);
comboImage.drawBitmap(map, 0, 0, null);
comboImage.drawBitmap(pic, 600, 350, null);**
