First letter capitalization for EditText

Statically (i.e. in your layout XML file): set android:inputType="textCapSentences" on your EditText.

Programmatically: you have to include InputType.TYPE_CLASS_TEXT in the InputType of the EditText, e.g.

EditText editor = new EditText(this); 
editor.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_FLAG_CAP_SENTENCES);

Can be combined with text and its variations to request capitalization of the first character of every sentence.

Just use android:inputType="textCapWords" in your EditText element.

For example:

<EditText
    android:id="@+id/txtName"
    android:layout_width="0dp"
    android:layout_height="40dp"
    android:layout_weight="0.7"
    android:inputType="textCapWords"
    android:textColorHint="#aaa"
    android:hint="Name Surname"
    android:textSize="12sp" />
