如何在android编码中在ImageView上写文本？

Question

嗨，我一直试图在Imageview上写数字。用于N个问题的图像。如果用户输入的答案是正确的，则应显示带有问号的问题编号和带有错误标记图像的问题编号。我需要在图像上写下问题编号。我的代码在这里：

    LinearLayout l_layout = (LinearLayout) findViewById(R.id.linear_view_report);
    LayoutParams param = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT, 1.0f);
    ImageView[] imgview=new ImageView[questions.length];
    for(int i=0;i<no_of_questions;i++)
    {
                if(userEnteredAnswers[i]==correct_answer[i]){           
                    Bitmap bm=BitmapFactory.decodeResource(getResources(),R.drawable.correct);
                    Canvas canvas = new Canvas(bm);
                    Paint paint = new Paint(); 
                    paint.setColor(Color.BLACK); 
                    paint.setTextSize(10); 
                    canvas.drawText(i, 5, 5, paint);

                    imgview[i]=new ImageView(this);
                    imgview[i].setImageDrawable(new BitmapDrawable(bm));
                    l_layout.addView(imgview[i]);
                }
                else {          
                    Bitmap bm=BitmapFactory.decodeResource(getResources(),R.drawable.wrong);
                    Canvas canvas = new Canvas(bm);
                    Paint paint = new Paint(); 
                    paint.setColor(Color.BLACK); 
                    paint.setTextSize(10); 
                    canvas.drawText(i, 5, 5, paint);

                    imgview[i]=new ImageView(this);
                    imgview[i].setImageDrawable(new BitmapDrawable(bm));
                    l_layout.addView(imgview[i]);
                }       
            }

我收到此警告：

The constructor BitmapDrawable(Bitmap) is deprecated

图片在运行时不显示。我究竟做错了什么？

我认为最简单的解决方法是不覆盖任何内容，而是TextView使用drawable资源设置其背景。

例如：

TextView t = (TextView)findViewById(R.id.my_text_view);
// setting gravity to "center"
t.setGravity(Gravity.CENTER);
t.setBackgroundResource(R.drawable.my_drawable);
t.setText("FOO");
