How do I write text over a picture in Android and save it?

Question

How can I write text on an image and then save it in Android?

Basically I want to let user write something on the images which my camera app will click for them. I can write and show it to them using the onDraw method on the preview of the camera. But after the user has clicked the picture I want to write the text over the picture and then save it.

You can put an EditText and write into it, and after writing, you first convert it to Bitmap like:

Bitmap bmp = Bitmap.createBitmap(mEditText.getDrawingCache());

Now you can add created image bmp to your original image like this:

Call: Bitmap combined = combineImages(bgBitmap,bmp);

public Bitmap combineImages(Bitmap background, Bitmap foreground) { 

        int width = 0, height = 0;
        Bitmap cs;

        width = getWindowManager().getDefaultDisplay().getWidth();
        height = getWindowManager().getDefaultDisplay().getHeight();

        cs = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
        Canvas comboImage = new Canvas(cs);
        background = Bitmap.createScaledBitmap(background, width, height, true);
        comboImage.drawBitmap(background, 0, 0, null);
        comboImage.drawBitmap(foreground, matrix, null);

        return cs;
    }
