Hi, I am trying to provide a default input value for an EditText input field.

Simplified code segment is as follows:-


package xxx.xxx.xxx;
.
.
public class UserInput extends Activity {
private EditText fieldInput;

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.userinput);

findView();
dataInput();
setListeners(); // code of setListeners() not included here for simplicity
}

private void findViews() {
fieldInput = (EditText)findViewById (R.id.field_input);
}

private void dataInput(){
//
myInput = "1234";
fieldInput.setText(myInput, TextView.BufferType.EDITABLE);
myInput = fieldInput.getText().toString();

}


The "1234" was displayed on the fieldInput View, after back space and type
different text on the input field and hit the button, the System.out.println
of myInput is still "1234".

I notice that while using Preference, it also use the similar .setText method,
but why the above code doesn't work?

Any help would be highly appreciated.

Try to set default value in layout file

Thank you vandzi.

Actually my default values are the present date and time obtained by the
calendar object. So it will change every time when the app is run.

Data input with supplied default values is, I believe, the function that most
Android developers longing for.

Thanks.

Do you have this code:
myInput = fieldInput.getText().toString();
in button onclick method?

Code: Select all

findView();
dataInput();
setListeners(); // code of setListeners() not included here for simplicity
}

private void findViews() {
fieldInput = (EditText)findViewById (R.id.field_input);
}

Your findView();
When you call it, it is being called as findViews(); that might also be causing an error

Hi vandzi,

I think we need to see the onclick code to see why it is not setting the output statement from the input edittext.
