How to capitalize every letter in an Android EditText?

Question

I have an array of editTexts which I make like this:

        inputs[i] = new EditText(this);
        inputs[i].setWidth(376);
        inputs[i].setInputType(         


        

Answer 1

Just use String.toUpperCase() method.

example :

String str = "blablabla";
editText.setText(str.toUpperCase()); // it will give : BLABLABLA

EDIT :

add this attribute to you EditText Tag in your layout xml :

 android:textAllCaps="true"

OR:

If you want whatever the user types to be uppercase you could implement a TextWatcher and use the EditText addTextChangedListener to add it, an on the onTextChange method take the user input and replace it with the same text in uppercase.

editText.addTextChangedListener(upperCaseTextWatcher);

final TextWatcher upperCaseTextWatcher = new TextWatcher() {

public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {
}

public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
    editText.setText(editText.getText().toString().toUpperCase());
    editText.setSelection(editText.getText().toString().length());
}

public void afterTextChanged(Editable editable) {
}

};

Answer 2

You can try this:

android:inputType="textCapCharacters"

It worked for me. =)

Answer 3

For some reason adding the xml did not work on my device.

I found that a Text Filter works for to uppercase, like this

    EditText editText = (EditText) findViewById(R.id.editTextId);

    InputFilter toUpperCaseFilter = new InputFilter() {
        public CharSequence filter(CharSequence source, int start, int end,
                                   Spanned dest, int dstart, int dend) {

            StringBuilder stringBuilder = new StringBuilder();

            for (int i = start; i < end; i++) {
                Character character = source.charAt(i);
                character = Character.toUpperCase(character); // THIS IS UPPER CASING
                stringBuilder.append(character);

            }
            return stringBuilder.toString();
        }

    };

    editText.setFilters(new InputFilter[] { toUpperCaseFilter });
