Emoji Rain

掉表情包咯~

这是一个特别小巧的Android掉emoji表情包实现。效果类似于微信中发送"生日快乐"和"么么哒"之类的词语时触发的动画效果。

现在你也可以把这个有趣的特性加入自己的app啦在圣诞节的时候给用户掉圣诞树emoji吧 :D

使用

Gradle依赖

dependencies {
    compile 'com.luolc:emoji-rain:0.1.1'
}

参数配置

  • per
    • 每一波掉落的emoji个数，默认6个
  • duration
    • 掉落动画持续的总时长，默认8000ms
  • dropDuration
    • 每个emoji掉落时长的平均值，默认2400ms
  • dropFrequency
    • 掉落频率，即每两拨的时间间隔，默认500ms

在layout中配置。 EmojiRainLayout继承自FrameLayout，你完全可以把它当做原生的FrameLayout使用。

<com.luolc.emojirain.EmojiRainLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:id="@+id/group_emoji_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:per="10"
        app:duration="7200"
        app:dropDuration="2400"
        app:dropFrequency="500"
        tools:context="com.luolc.emojirain.sample.MainActivity">

    <TextView
            android:text="Hello world!"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"/>
</com.luolc.emojirain.EmojiRainLayout>

在Java代码中配置。

public class MainActivity extends AppCompatActivity {

    private EmojiRainLayout mContainer;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // bind view
        mContainer = (EmojiRainLayout) findViewById(R.id.group_emoji_container);

        // add emoji sources
        mContainer.addEmoji(R.drawable.emoji_1_3);
        mContainer.addEmoji(R.drawable.emoji_2_3);
        mContainer.addEmoji(R.drawable.emoji_3_3);
        mContainer.addEmoji(R.drawable.emoji_4_3);
        mContainer.addEmoji(R.drawable.emoji_5_3);

        // set emojis per flow, default 6
        mContainer.setPer(10);

        // set total duration in milliseconds, default 8000
        mContainer.setDuration(7200);

        // set average drop duration in milliseconds, default 2400
        mContainer.setDropDuration(2400);

        // set drop frequency in milliseconds, default 500
        mContainer.setDropFrequency(500);
    }
}

开始掉落。

mContainer.startDropping();

停止掉落。

mContainer.stopDropping();
