Introduction

Reveal the effect layout, you can specify 2 sub-layouts, and switch the selected state with the circular reveal effect.

Source

The code in this repository was inspired from goweii/RevealLayout - v1.3.4. We are very thankful to goweii Goweii and mbacuiz.

Integration method

##Add dependency

In order to use the library, add the following line to your root gradle file:

1.Add dependency in build.gradle of project app directory Starting from version 4.13.1, v is not added before the version number, and you need to pay attention to it when quoting.

    dependencies {
        implementation fileTree(dir: 'libs', include: ['*.jar', '*.har'])
        testImplementation 'junit:junit:4.13.1'
        ohosTestImplementation 'com.huawei.ohos.testkit:runner:1.0.0.200'
        implementation project(':reveallayout')
    }

2.For using RevealLayout in separate application using har file, add the har file in the entry/build.gradle file.

	dependencies {
            implementation fileTree(dir: 'libs', include: ['*.har'])
            testImplementation 'junit:junit:4.13.1'
            ohosTestImplementation 'com.huawei.ohos.testkit:runner:1.0.0.200'
	}

3.For using RevealLayout from a remote repository in separate application, add the below dependencies in entry/build.gradle file.

	dependencies {
           implementation 'dev.applibgroup:reveallayout:1.0.0'
           testCompile 'junit:junit:4.12'
	}

Usage

To use RevealLayout in your app simply follow below simple steps:

Layout file reference

<per.goweii.reveallayout.RevealLayout ohos:id="$+id:reveal_layout" ohos:width="match_content" ohos:height="match_content" ohos:padding="15vp" app:rl_allowRevert="false" app:rl_animDuration="1000" app:rl_checkWithExpand="true" app:rl_checked="false" app:rl_checkedLayout="$layout:reveal_layout_follow_checked" app:rl_uncheckWithExpand="true" app:rl_uncheckedLayout="$layout:reveal_layout_follow_unchecked" />

Set up monitoring in the code

Custom subclass

For example, a follow and unfollow control FollowView only needs to inherit RevealLayout, and then copy the following 3 methods:

initAttr(AttributeSet attrs): Get the custom attributes of the subclass createCheckedView(): Create a selected state view and initialize custom properties createUncheckedView(): Create an unchecked view and initialize custom attributes

####initAttr()

public class RevealLayout extends StackLayout implements Checkable, ValueUpdateListener, Animator.StateChangedListener, Component.TouchEventListener { private Component mCheckedView; private Component mUncheckedView; private int mCheckedLayoutId = 0; private int mUncheckedLayoutId = 0; private int mAnimDuration = 500; private boolean mCheckWithExpand = true; private boolean mUncheckWithExpand = false; private boolean mAllowRevert = false; private boolean mHideBackView = true; private boolean mChecked = false; private float mCenterX = 0F; private float mCenterY = 0F; private float mRevealRadius = 0F; private float mStart = 0F; private float mEnd = 0F; private final Path mPath = new Path(); private AnimatorValue mAnimator; private static final String VIEW_CHECKED = "rl_checkedLayout"; private static final String VIEW_UNCHECKED = "rl_uncheckedLayout";

public RevealLayout(Context context) {
    this(context, null);
    setTouchEventListener(this);
}

public RevealLayout(Context context, AttrSet attrs) {
    this(context, attrs, 0);
    setTouchEventListener(this);
}

public RevealLayout(Context context, AttrSet attrs, int defStyleAttr) {
    super(context, attrs);
    initAttr(attrs);
    initView(context);
    setTouchEventListener(this);
    setClickedListener(this);

}

####createCheckedView()

protected Component createCheckedView(Context context) { Component checkedView; if (getCheckedLayoutId() > 0) { checkedView = LayoutScatter.getInstance(getContext()).parse(getCheckedLayoutId(), null, false); } else { checkedView = new Component(getContext()); } return checkedView; }

####createUncheckedView

protected Component createUncheckedView(Context context) { Component uncheckedView; if (getUncheckedLayoutId() > 0) { uncheckedView = LayoutScatter.getInstance(getContext()).parse(getUncheckedLayoutId(), this, false); } else { uncheckedView = new Component(getContext()); } return uncheckedView; }
