My xml code is:

    <?xml version="1.0" encoding="utf-8"?>

    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"

            android:layout_weight="1"
            android:src="@drawable/del"></ImageButton>
    </LinearLayout>

    </LinearLayout>

My Activity code where edtEdit onClick not working is:

public class Income extends AppCompatActivity {
    TextView edtTextMonth , edtTextTitle, edtTextDate, edtTextIncome;
    TableLayout tableLayoutDisplay;
    ImageButton btnNext, btnPrev, btnEdit;
    DBHelper myDB;
    int monthNumber = 12, year = 1964;
    String monthName, prevNext;
    String T1, T2, T3; // selected row values
    int activity = 0, tr; // '0' as an IncomeActivity in DBHelper insertData method.

    @Override
    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_income);

        myDB = new DBHelper(this);
        edtTextMonth = (TextView) findViewById(txtViewMonth);
        edtTextDate = (EditText) findViewById(R.id.editTextDate);
        edtTextTitle = (EditText) findViewById(R.id.editTextTitle);
        edtTextIncome = (EditText) findViewById(R.id.editTextIncome);
        btnNext = (ImageButton) findViewById(R.id.btnNext);
        btnPrev = (ImageButton) findViewById(R.id.btnPrev);
        btnEdit = (ImageButton) findViewById(R.id.btnEdit);

    }
public void editIncomeValues(View view) {
        AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(Income.this);
        alertDialogBuilder.setTitle("Edit");
        alertDialogBuilder.setMessage("Are you sure, You wanted to make decision");
                alertDialogBuilder.setPositiveButton("yes", new DialogInterface.OnClickListener() {
                            @Override
                            public void onClick(DialogInterface arg0, int arg1) {
                                edtTextTitle.setText(T1);
                                edtTextDate.setText(T2);
                                edtTextDate.setText(T3);
                                edtTextTitle.requestFocus();
                            }
                        })
                .setNegativeButton("No",new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        dialog.cancel();
                    }
                });

        AlertDialog alertDialog = alertDialogBuilder.create();
        alertDialog.show();
    }

}

Answer 1

I see that on click "editIncomeValues()" is called where you are showing of dialog.

I guess you are facing issue because you have set actions for Alert Dialog - alertDialogBuilder and performed show on a new dialog - alertDialog .

Your code is perfect. Just change dont create another alertDialog(alertDialog) and use the same one created(alertDialogBuilder) for showing as well...

Goodluck..! Hope it helps :)

Answer 2

You don't need to create AlertDialog just delete this line:

  AlertDialog alertDialog = alertDialogBuilder.create();

and change the last line to :

alertDialogBuilder.show();
