Answer 1

Use the for loop.

 private boolean validate(EditText[] fields){ for(int i = 0; i < fields.length; i++){ EditText currentField = fields[i]; if(currentField.getText().toString().length() <= 0){ return false; } } return true; } 

and use a method like this:

 boolean fieldsOK = validate(new EditText[] { ev_last_name, ev_first_name, ev_email }) 

will return true if all fields are not empty.

Answer 2

 private boolean isEmptyField (EditText editText){ boolean result = editText.getText().toString().length() <= 0; if (result) Toast.makeText(context, "Fill all fielsd!", Toast.LENGTH_SHORT).show(); return result; } BtnSave.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { if (isEmptyField(ev_last_name)) return; if (isEmptyField(ev_first_name)) return; // your logic here; ... } }); 

Answer 3

 EditText resultInput = (EditText)findViewById(R.id.result); if(resultInput.getText().length() > 0) // Edit Text is Empty else // Edit Text is Empty
