简体中文版说明 >>>

A Library to develop emotion-input layout like WeChat, Telegram, etc.

Download

Add it in your build.gradle at the end of repositories:

allprojects {
	repositories {
		jcenter()
		maven { url "https://jitpack.io" }
	}
}

Add the dependency in the form:

dependencies {
	compile 'com.github.dss886:Android-EmotionInputDetector:v0.2.0'
}

Usage

1.Make sure the root layout of your activity is a LinearLayout, and there are a view/layout of variable height in it (like a ListView or a RelativeLayout). Set the height-variable view/layout's layout_height as 0 and the layout_weight as 1

2.Add your custom emotion-input layout at the bottom of your activity layout:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <ListView
        android:id="@+id/list"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        />

    <include
		layout="@layout/reply_layout"
		android:layout_width="match_parent"
		android:layout_height="wrap_content"/>

</LinearLayout>

3.then custom your reply_layout.xml to show editText and emotion layout (e.g using a ViewPager as the Sample module)

4.Use EmotionInputDetector

EmotionInputDetector.with(this)
	    .setEmotionView(emotionView)
	    .bindToContent(contentView)
	    .bindToEditText(editText)
	    .bindToEmotionButton(emotionButton)
	    .build();

There are 4 views:

• emotionView: the layout to show clickable emotions.
• contentView: the height-variable view/layout in the root layout.
• editText: the EditText need to bind.
• emotionButton: the button to switch emotion layout's visibility.

the relationship of these views:

Options

For better performance, using EmotionInputDetector.interceptBackPress() method in the override method onBackPressed() of your activity, to determine whether the back pressed action should be intercepted.

@Override
public void onBackPressed() {
    if (!mDetector.interceptBackPress()) {
        super.onBackPressed();
    }
}
