RememberEditText 
An EditText which can remember last input, free developer from managing cache everywhere themselves.
Introduction
Have you been annoyed with entering the same stuff once and once like username, thread-reply? RememberEditText can remember the last several input automatically and offers a dropdown list to let user choose.
How
View: RememberEditText is an EditText view, but not a viewgroup extends linearlayout like some project. I made it so in order to decrease view layers.
Cache: RememberEditText simply puts its cache in SharedPreference, and keeps a local hashmap version to free from visiting SharedPreference everytime, thus speeds up its looks up and update.
Usage
dependencies {
compile 'cn.zhaiyifan:rememberedittext:0.9.0'
}
<cn.zhaiyifan.rememberedittext.RememberEditText
android:id="@+id/username"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_marginLeft="@dimen/activity_horizontal_margin"
android:layout_marginRight="@dimen/activity_horizontal_margin"
android:layout_marginTop="150dp"
android:hint="Username/PhoneNumber"
android:inputType="text"
app:rememberCount="3"
app:rememberId="username" />styles:
<declare-styleable name="RememberEditText">
<!-- auto fill in cache, by default true -->
<attr name="autoFill" format="boolean" />
<!-- auto save to cache, by default true -->
<attr name="autoSave" format="boolean" />
<!-- dropdown icon to choose between cache values, by default use abc_spinner_mtrl_am_alpha -->
<attr name="dropDownIcon" format="reference" />
<!-- delete icon to delete cache value, by default use abc_ic_clear_mtrl_alpha -->
<attr name="deleteIcon" format="reference" />
<!-- id of cache, will use view id if not set -->
<attr name="rememberId" format="string" />
<!-- count of cache to keep, by default 3 -->
<attr name="rememberCount" format="integer" /> </declare-styleable>TODO
- Make cache loading async.
- Add more hint mode.
- Enable pair mode, like username/password.
- Center gravity is not supported yet, need help (icon is missing when set center gravity).
- Add encrpytion mode to save stuff like password (low priority).
- Support RTL (Right to Left).
