Full Text not showing into image

Question

I am trying to convert text into image using below code :

    public Bitmap textAsBitmap(String text, float textSize) {
     Paint paint = new Paint(ANTI_ALIAS_FLAG);
     paint.setTextSize(textSize);
     paint.setColor(Color.BLACK);
     paint.setStyle(Paint.Style.FILL_AND_STROKE);
     paint.setTextAlign(Paint.Align.CENTER);
     float baseline = -paint.ascent(); // ascent() is negative
     int width = (int) (paint.measureText(text) + 0.5f); // round
      int height = (int) (baseline + paint.descent() + 0.5f);
      Bitmap image = Bitmap.createBitmap(width, height, 
      Bitmap.Config.ARGB_8888);
     Canvas canvas = new Canvas(image);
     canvas.drawText(text, 0, baseline, paint);
    return image;
}

Its convert text into image but problem is show half text.It should show "favorite subject is english"!

@buzzingsilently actually i can not use textview or image view ,I have to convert string text to image — Usman Saeed, May 21 '18 at 11:30
You have to measure the view height and width. Then try to make your text fit in that dimensions. The problem here is, I think your generated image is bigger than view size. — Aswin P Ashok, May 21 '18 at 11:44

Choose your width & height wisely, Something like I did in my case

public Bitmap textAsBitmap(String text, float textSize) {
    Paint paint = new Paint(ANTI_ALIAS_FLAG);
    paint.setTextSize(textSize);
    paint.setColor(Color.BLACK);
    paint.setTextAlign(Paint.Align.LEFT);
    float baseline = -paint.ascent(); // ascent() is negative
    int width = (int) (paint.measureText(text) + 0.0f); // round
    int height = (int) (baseline + paint.descent() + 0.0f);

    int actualWidth = width;
    if (width > height) 
        height = width;
    else 
        width = height;
    Bitmap image = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);

    Canvas canvas = new Canvas(image);
    canvas.drawText(text, width / 2 - actualWidth / 2, baseline, paint);
    return image;
}

Problem is with paint.setTextAlign(Paint.Align.CENTER);, this property considers center as (0,0). So your text is actually at center according to (0,0).

Just remove paint.setTextAlign(Paint.Align.CENTER); and your code is working!!
