A Library to develop emotion-input layout like WeChat, Telegram, etc.
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'
}
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:
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();
}
