生活随笔收集整理的這篇文章主要介紹了 Android监听左右滑删除通知,Android 滑动监听RecyclerView线性流+左右划删除+上下移动... 小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

廢話不多說了，直接給大家貼代碼了。具體代碼如下所示:

xmlns:tools="http://schemas.android.com/tools"

android:layout_width="match_parent"

android:layout_height="match_parent"

tools:context="c.example.jreduch10.recycler1activity">

android:layout_width="match_parent"

android:layout_height="match_parent"

android:id="@+id/rv"

package c.example.jreduch10;

import android.os.bundle;

import android.support.v7.app.appcompatactivity;

import android.support.v7.widget.linearlayoutmanager;

import android.support.v7.widget.recyclerview;

import android.support.v7.widget.helper.itemtouchhelper;

import android.util.log;

import android.view.view;

import android.view.viewgroup;

import android.widget.imageview;

import android.widget.textview;

import android.widget.toast;

import java.util.arraylist;

import java.util.list;

import c.example.jreduch10.entity.video;

import jp.wasabeef.recyclerview.adapters.alphainanimationadapter;

import jp.wasabeef.recyclerview.adapters.scaleinanimationadapter;

public class recycler1activity extends appcompatactivity {

private recyclerview rv;

private list list;

private adapter adapter;

private itemtouchhelper itemtouchhelper;

@override

protected void oncreate(bundle savedinstancestate) {

super.oncreate(savedinstancestate);

setcontentview(r.layout.activity_recycler1);

rv=(recyclerview)findviewbyid(r.id.rv);

list=new arraylist<>();

initdata();

adapter=new adapter(list);

linearlayoutmanager llm=new linearlayoutmanager(this);

llm.setorientation(linearlayoutmanager.vertical);

rv.setlayoutmanager(llm);

// rv.setadapter(adapter);

//動畫效果

alphainanimationadapter alphainanimationadapter=new alphainanimationadapter(adapter);

rv.setadapter(new scaleinanimationadapter(alphainanimationadapter));

//默認動畫效果

// rv.setitemanimator(new defaultitemanimator());

itemtouchhelper=createitemtouchhelper();

itemtouchhelper.attachtorecyclerview(rv);

監聽事件某一行

// recyclerviewitemlistener listener=new recyclerviewitemlistener(this, new recyclerviewitemlistener.onitemclicklistener() {

// @override

// public void onitemclick(view item, int adapterposition) {

// toast.maketext(getbasecontext(),adapterposition+"",toast.length_short).show();

// }

// });

// rv.addonitemtouchlistener(listener);

}

public itemtouchhelper createitemtouchhelper(){

itemtouchhelper=new itemtouchhelper(new itemtouchhelper.callback() {

@override

public int getmovementflags(recyclerview recyclerview, recyclerview.viewholder viewholder) {

//拖拽時支持的方向向上向下

int dragflags=itemtouchhelper.up|itemtouchhelper.down;

//滑動的時候支持的方向為左右

int swipeflags=itemtouchhelper.left|itemtouchhelper.right;

//必須調用makemovementflags()方法通知 touchhelper支持的種類

return makemovementflags(dragflags,swipeflags);

}

//上下拖動回調次方法。

@override

public boolean onmove(recyclerview recyclerview, recyclerview.viewholder viewholder, recyclerview.viewholder target) {

adapter.move(viewholder.getadapterposition(),target.getadapterposition());

return true;

}

//左右滑動回調此方法。

@override

public void onswiped(recyclerview.viewholder viewholder, int direction) {

adapter.delete(viewholder.getadapterposition());

}

@override

public boolean isitemviewswipeenabled() {

return super.isitemviewswipeenabled();

}

@override

public boolean islongpressdragenabled() {

return super.islongpressdragenabled();

}

});

return itemtouchhelper;

}

public void initdata(){

video video=new video(r.mipmap.zyf,"國產","........");

list.add(video);

video=new video(r.mipmap.zyfzyf,"國產","........");

list.add(video);
