How to force EditText to start text with capital letter?

Be careful if you add both android:capitalize="sentences" and android:inputType="text", as the latter seems to have priority over the first and the input will not be capitalized.

There's a specific inputType for automatically capitalizing the first letter:

android:inputType="textCapSentences"

See http://developer.android.com/reference/android/widget/TextView.html#attr_android:inputType

Use

android:inputType="textPersonName|textCapWords"

as using only "textPersonName" is not enough so name's first letters would be capitalized.

Similarly with postal addresses:

android:inputType="textPostalAddress|textCapSentences"

The options for android:capitalize are

android:inputType="none", which won't automatically capitalize anything.

android:inputType="sentences", Which will capitalize the first word of each sentence.

android:inputType="words", Which Will Capitalize The First Letter Of Every Word.

android:inputType="characters", WHICH WILL CAPITALIZE EVERY CHARACTER.

Apparently it has been changed to inputType instead of capitalize

Add this in your XML

 android:inputType="textCapWords"

android:inputType="textCapSentences" will work for sentences. However, I needed to capitalize every word in a full name field.
