1,可以在布局文件中設置

 <EditText
        android:id="@+id/editText1"
        android:textColor="#2BD54D"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" >
    </EditText>

2，在代碼中顯示html代碼

editText2.setText(Html.fromHtml(  "<font color=#E61A6B>紅色代碼</font> "+ "<i><font color=#1111EE>藍色斜體代碼</font></i>"+"<u><i><font color=#1111EE>藍色斜體加粗體下劃線代碼</font></i></u>"));
