This is a Material-Design-login Demo. You can set the state(Sign-Up or Login) by slip events in this demo, or you can create other animations when the progress callback.

How To Implements

CatchScrollLayout

CatchScrollLayout is responsible for monitoring external sliding events. You can set the area of monitored by setting the height of CatchScrollLayout (“match_parent” usually).

<yellow5a5.materialdesignlogin.View.CatchScrollLayout
    android:id="@+id/catch_sroll_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center_horizontal"
    android:orientation="vertical"
    android:clickable="true">

    <!--add the view like this-->

    <yellow5a5.materialdesignlogin.View.SignUpContainer
        android:id="@+id/sign_up_container"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"/>


</yellow5a5.materialdesignlogin.View.CatchScrollLayout>

Set the IScrollCallBack do anything you want.

private IScrollCallBack mIScrollCallBack;

public interface IScrollCallBack {
    void onScrollProcess(int process, boolean isLeft);
}

public void setIScrollCallBack(IScrollCallBack l) {
    mIScrollCallBack = l;
}

UnderlineDevider

You can change the number of segments by UnderlineDevider. Set it in xml (app:devide_count) or call the method (setDevider). UnderlineDevider is independent, you can use it in any other place.

<yellow5a5.materialdesignlogin.View.UnderlineDevider
    android:id="@+id/underline_v"
    android:layout_width="match_parent"
    android:layout_height="2dp"
    android:layout_gravity="bottom"
    app:devide_color="#ffffff"
    app:devide_count="2" />

Demo－Introduction

This design ideas come from Material Design Sign Up / Login (by Dhanish). You can set the state(Sign-Up or Login) by slip events. SignUpContainer should contains the logic of logining and registering. It's easy to add other task you wanted or change the method in callback.

mCatchScrollLayout.setIScrollCallBack(new CatchScrollLayout.IScrollCallBack() {
    @Override
    public void onScrollProcess(int process, boolean isLeft) {
        if (!isLeft){
            process = 100 - process;
        }
        mSignUpContainer.setAnimProportion(process);
    }
});

mSignUpContainer.setIConfirmCallBack(new SignUpContainer.IConfirmCallBack() {
    @Override
    public void goNext() {
        //TODO
    }
});
