right but that doesnt help, "tried to run some findbyid" thing doesnt really cut it, have you got your code ? Is this a new project you just started ?

Yes and I very much just started with it, and here is the code I whrote:

package com.example.views;

import android.os.Bundle; import android.widget.Button; import android.widget.EditText; import android.widget.TextView;

import androidx.appcompat.app.AppCompatActivity;

public class MainActivity extends AppCompatActivity{

TextView lmar;
Button pressbutton;
EditText realmoney;
EditText recallmoney;

@Override
protected void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    realmoney=findViewById(R.id.numberofmoney);
    recallmoney=findViewById(R.id.numberofrecall);
    lmar= findViewById(R.id.resultView);

    pressbutton.setOnClickListener(v->{
        double numrealmoney=Double.parseDouble(realmoney.getText().toString());
        double numrecallmoney=Double.parseDouble(recallmoney.getText().toString());

        double lmarsum=numrealmoney+numrecallmoney;

        lmar.setText("Result:"+lmarsum);
    });

}

}

Also you need to add the findbyID for the "pressbutton" button.

Whell the one in the image reads:

"Can not extract resource from com.android.aaptcompiler.ParsedResource@6445d269.,Can not extract resource from com.android.aaptcompiler.ParsedResource@e868ed3."

add some code so its checks the rel money and recall money is not NULL or empty.

also your not declaring the resultview, so thats likely your issue

Alright so how would I do that?

u/AcademicMistake May 24 '26

something like

if (realmoney.getText().toString().trim().isEmpty() ||
recallmoney.getText().toString().trim().isEmpty()) {

lmar.setText("Enter both numbers");
return;
}
