Displaying list view Items when button is clicked

Question

I am creating a Tables app ie When a number is entered in editText and button is pressed, The list view will show the table of that certain number. I tried this code but it keeps crashing.

public class MainActivity extends AppCompatActivity {

    ListView myListView;

    public final void generate(int timesTableNumber){
        ArrayList<String> timeTableContent= new ArrayList<String>();

        for(int j=1;j<=10;j++)
            timeTableContent.add(Integer.toString(j*timesTableNumber));

        ArrayAdapter<String> arrayAdapter=new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,timeTableContent);

        myListView.setAdapter(arrayAdapter);
    }

    public void table(View view)
    {
        EditText editText=(EditText)findViewById(R.id.editText);
        generate(Integer.parseInt(editText.toString()));
    }



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

        myListView=findViewById(R.id.myListView);

        generate(1);



    }
}

Answer 1

You should add getText() .

 generate(Integer.parseInt(editText.getText().toString()));

Then use String.valueOf instead of Integer.toString .

        for(int j=1;j<=10;j++)
        timeTableContent.add(String.valueOf(j*timesTableNumber));
