如何在图像视图的随机位置上传递许多textview？

Question

现在我在使用Canvas和Bitmap的图像上仅获得一个Text： 这是我的代码：

   public Bitmap drawTextArrayToBitmap(Context mContext, int resourceId,String mText) {
    try {
        Resources resources = mContext.getResources();
        float scale = resources.getDisplayMetrics().density;
        Bitmap bitmap = BitmapFactory.decodeResource(resources, resourceId);
        android.graphics.Bitmap.Config bitmapConfig =   bitmap.getConfig();

        if(bitmapConfig == null) {
            bitmapConfig = android.graphics.Bitmap.Config.ARGB_8888;
        }

        bitmap = bitmap.copy(bitmapConfig, true);

        Canvas canvas = new Canvas(bitmap);

        Paint paint = new Paint(Paint.ANTI_ALIAS_FLAG);
        paint.setColor(Color.rgb(110,110, 110));
        paint.setTextSize((int) (12 * scale));
        paint.setShadowLayer(1f, 0f, 1f, Color.DKGRAY);

        Rect bounds = new Rect();
        paint.getTextBounds(mText, 0, mText.length(), bounds);

       /* int x = (bitmap.getWidth() - bounds.width())/6;
        int y = (bitmap.getHeight() + bounds.height())/5;*/

        int x = 100, y = 100;
        for(int i=0;i<20;i++)
        {

            canvas.drawText(mText, x * scale, y * scale, paint);
        }
        return bitmap;
    } catch (Exception e) {
        // TODO: handle exception

        return null;
    }

}

在oncreate内部；

     ImageView mImageView = (ImageView)findViewById(R.id.imageView1);

  //  Bitmap bmp =drawTextToBitmap(this,R.drawable.man,"Hello Android");

    Bitmap bmp =drawTextArrayToBitmap(this,R.drawable.man,"Smile");
    mImageView.setImageBitmap(bmp);

在上面的代码中，我想在Image和其他样式的随机位置上添加多个文本，我尝试了很多时间仍无法成功。我也尝试过内循环。

预先感谢您，
