在Android EditText中按字母换行

Question

How to break Line by letters in android EditText , so it became like this:

Hello how to br
eak by letters
instead of word
s

Instead of this:

Hello how to
break by 
letters
instead of 
words

The analog in css is word-break: break-all

PS Of course Text is dynamically changing.

Answer 1

Try this // tmpString - the string to display

//15 - no. of letters you want change according to your requirement

int index = 0;
StringBuffer finalString = new StringBuffer(); 
while (index < tmpString.length()) {
    finalString.append(tmpString.substring(index, Math.min(index + 15,tmpString.length()))+"\n");
    index += 15;
}
editText.setText(finalString);

Answer 2

It calls 'justify text' or 'text justification', but in Android it is not supported, at least until now.

There a kind of solution if you want to implement. It is to use WebView and load the text in HTML format and set the body style to justify . It is just a solution if you really need 'text justification'.

Answer 3

You can use auto resize edit text with following properties:

android:inputType="textMultiLine"
android:layout_height="wrap_content"

Full EditText layout example:

<EditText
   android:layout_width="match_parent"
   android:inputType="textMultiLine"
   android:layout_height="wrap_content"
   android:hint="Enter Text"
   android:textColorHint="@color/primary_color"
   android:ems="10"
   android:imeOptions="actionDone"
   android:id="@+id/message_input"
   android:layout_gravity="center_horizontal"/>
