This should give you the required layout:

这将给您所需的布局:

Play with the android:layout_marginTop="20dp" to see which one suits you better. Use the id textview to dynamically set the android:text value.

使用android:layout_marginTop=“20dp”，看看哪个更适合您。使用id textview来动态设置android:文本值。

Since a RelativeLayout stacks its children, defining the TextView after ImageView puts it 'over' the ImageView.

由于RelativeLayout叠加了其子元素，所以在ImageView后定义TextView会将其置于ImageView之上。

NOTE: Similar results can be obtained using a FrameLayout as the parent, along with the efficiency gain over using any other android container. Thanks to Igor Ganapolsky(see comment below) for pointing out that this answer needs an update.

注意:类似的结果可以使用FrameLayout作为父程序，以及使用其他任何android容器的效率提高。感谢Igor Ganapolsky指出，这个答案需要更新。

As you mentioned in OP, you need to overlay Text on ImageView programmatically way. You can get ImageView drawable and write on it with the help of putting it on Canvas and Paint.

正如您在OP中提到的，您需要以编程方式在ImageView上覆盖文本。您可以获得ImageView drawable，并通过将它放在Canvas和Paint的帮助在上面进行编写。

 private BitmapDrawable writeTextOnDrawable(int drawableId, String text) 
 {
 Bitmap bm = BitmapFactory.decodeResource(getResources(), drawableId).copy(Bitmap.Config.ARGB_8888, true);
 Typeface tf = Typeface.create("Helvetica", Typeface.BOLD);
 Paint paint = new Paint();
 paint.setStyle(Style.FILL);
 paint.setColor(Color.WHITE);
 paint.setTypeface(tf);
 paint.setTextAlign(Align.CENTER);
 paint.setTextSize(11);
 Rect textRect = new Rect();
 paint.getTextBounds(text, 0, text.length(), textRect);
 Canvas canvas = new Canvas(bm);
 canvas.drawText(text, xPos, yPos, paint);
 return new BitmapDrawable(getResources(), bm);
 }

Maybe you should just write the ImageView first and the TextView second. That can help sometimes. That's simple but I hope it helps somebody. :)

也许你应该先写ImageView然后再写TextView。有时可以帮助。这很简单，但我希望它能帮助别人。:)
