            final EditText editTextNameAddBlockNum = (EditText) add_block_dialog.findViewById(R.id.editTextNameAddBlockNum);
            EditText editTextContactAddBlockNum = (EditText) add_block_dialog.findViewById(R.id.editTextContactAddBlockNum);
            final EditText editTextNumberAddBlockNum = (EditText) add_block_dialog.findViewById(R.id.editTextNumberAddBlockNum);

                        Toast.makeText(getApplicationContext(),"plz insert a name",Toast.LENGTH_SHORT).show();
                    }
                    if (editTextNumberAddBlockNum.getText().toString().equals(null)) {
                        Toast.makeText(getApplicationContext(),"plz insert a number",Toast.LENGTH_SHORT).show();
                    }
                    if (!editTextNumberAddBlockNum.getText().toString().equals(null) && !editTextNumberAddBlockNum.getText().toString().equals(null) ) {
                        Toast.makeText(getApplicationContext(),"successfuly saved",Toast.LENGTH_SHORT).show();
                    }
                }
            });

            add_block_dialog.show();

but when i click on the button it always shows successfuly saved. even when the edit texts are null.

Change this

if (editTextNameAddBlockNum.getText().toString().equals(null))

To

if (editTextNameAddBlockNum.getText().toString().equals(""))
