Android Espresso: test dynamically created buttons that do not have IDs assigned

I have multiple buttons that are created dynamically in a for loop and are not having an ID. I need to do automation testing on those buttons. How can I do this with Espresso? This is the for loop that creates the various buttons:

 for (int i = 0; i < numberOfSamples; i++) {
            TableRow.LayoutParams vl = new TableRow.LayoutParams(30,30);
            Button b = new Button(context);
            b.setId(((blockNumber * 10000)+i));
            //b.setHint(i);
            //b.setHint(blockNumber);
    //      double selectedGrade = 0;
    //      if(FinalSurvey.multi[blockNumber][i] != 0){
    //          selectedGrade = FinalSurvey.multi[blockNumber][i];
    //      }
    //      final int makeHighlight = selectedGrade;
            b.setBackgroundDrawable(context.getResources().getDrawable(R.drawable.a));
            b.setAlpha(1.0f);
            b.setOnClickListener(new View.OnClickListener() {

                @Override
                public void onClick(View v) {
                    ViewsAdding va = new ViewsAdding();
                    va.showGrades(context, v, grades);
                    view = v;
                    maincontext = context;
                }
            });

            if(i%5 == 0){
                innerLayout = new LinearLayout(context);
                innerLayout.setOrientation(LinearLayout.HORIZONTAL);
                innerLayout.setLayoutParams(innerparams);
                vl.setMargins(5, 5, 5, 5);
                b.setLayoutParams(vl);
                innerLayout.addView(b);
                if(i == numberOfSamples-1){
                    mainLinearLayout.addView(innerLayout);
                }
                b = null;
            }else if (i%5 ==1) {
                vl.setMargins(22, 5, 5, 5);
                b.setLayoutParams(vl);
                innerLayout.addView(b);
                if(i == numberOfSamples-1){
                    mainLinearLayout.addView(innerLayout);
                }
                b = null;
            }else if (i%5 ==2) {
                vl.setMargins(25, 5, 5, 5);
                b.setLayoutParams(vl);
                innerLayout.addView(b);
                mainLinearLayout.addView(innerLayout);
                b = null;
            }else if (i%5 ==3) {
                innerLayout = new LinearLayout(context);
                innerLayout.setOrientation(LinearLayout.HORIZONTAL);
                innerLayout.setLayoutParams(innerparams);
                vl.setMargins(35, 5, 5, 5);
                b.setLayoutParams(vl);
                innerLayout.addView(b);
                if(i == numberOfSamples-1){
                    mainLinearLayout.addView(innerLayout);
                }
                b = null;
            }else{
                vl.setMargins(30, 5, 5, 5);
                b.setLayoutParams(vl);
                innerLayout.addView(b);
                mainLinearLayout.addView(innerLayout);
                b = null;
            }
        }
        return mainLinearLayout;
    }

In your code where you create the buttons add a tag to the button depending on the case:

button.setTag("someTag");

so in your case you could do it in your if clauses:

       if(i%5 == 0){
            ...
            b.setTag("case0-" + i);
            ...
        }else if (i%5 ==1) {
            ...
            b.setTag("case1-" + i);
            ...
        }
        ...

and then in your test you can get the buttons with this or click it:

onView(allOf(withTagValue(is((Object) "case0-0")), isDisplayed())).perform(click());
onView(allOf(withTagValue(is((Object) "case0-0")), isDisplayed())).perform(click());

you can also replace the "case0-0" string with a loop to regenerate the tags
