I want to use findViewById with strings as an Id

Question

I am new to Android Studio and just trying to learn new ways to code and I'm stuck right now. I would like to use a String in a findViewById for example.

public void BDate0(String BId, String BHistoryClass) {
        bdatum0 = (Button) findViewById(R.id.BId);
        bdatum0.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent BDatum0 = new Intent(bethistory.this, BHistoryClass.class);
                startActivity(BDatum0);
            }
        });
    }

and I would like to call the BDate0 with the strings for example,

BDate0(BId1, BHistory1);

I have 10 buttons and the activity they start would be different every day.

Sorry for bad englihs it's not my native language and thank you for help in advance.

You can use this code to replace the findViewById(..). This should make it possible to use a string as identifier:

String BId = "button1"; // for example 
int id = getResources().getIdentifier(BId, "id", getPackageName());
// finds R.id.button1
bdatum0 = (Button) findViewById(id);
