Android SwipeListView 详解 实现微信,QQ等滑动删除效果

释放双眼,带上耳机,听听看~!

 

今天看别人项目,看到别人使用了SwipeListView,Google一把,果然github上的,也参考了csdn上的几篇文章,然后自己写了个例子,分享给大家。

效果图:

嗯,看一眼SwipeListView的参数的设置:

If you decide to use SwipeListView as a view, you can define it in your xml layout like this:

    <com.fortysevendeg.swipelistview.SwipeListView
xmlns:swipe="http://schemas.android.com/apk/res-auto"
android:id="@+id/example_lv_list"
android:listSelector="#00000000"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
swipe:swipeFrontView="@+id/front"
swipe:swipeBackView="@+id/back"
swipe:swipeActionLeft="[reveal | dismiss]"
swipe:swipeActionRight="[reveal | dismiss]"
swipe:swipeMode="[none | both | right | left]"
swipe:swipeCloseAllItemsWhenMoveList="[true | false]"
swipe:swipeOpenOnLongPress="[true | false]"
swipe:swipeAnimationTime="[miliseconds]"
swipe:swipeOffsetLeft="[dimension]"
swipe:swipeOffsetRight="[dimension]"
/>
  • swipeFrontView – Required – front view id. 即ListView Item正常显示的控件Id,且必须与Item的布局文件中的控件id一样
  • swipeBackView – Required – back view id.  手指滑动时显示的,隐藏在FrontView后面,且必须与item的布局文件中控件Id一样
  • swipeActionLeft – Optional – left swipe action Default: ‘reveal’  左滑的动作,默认reveal,即显示BackView,还有dismiss,choice会触发响应的方法。
  • swipeActionRight – Optional – right swipe action Default: ‘reveal’ 同上
  • swipeMode – Gestures to enable or ‘none’. Default: ‘both’ 设置左滑、右滑、都支持
  • swipeCloseAllItemsWhenMoveList – Close revealed items on list motion. Default: ‘true’ 当滚动listview时,关闭所有展开的Item,最好不要设置为false,由于item的复用,false存在一些问题。
  • swipeOpenOnLongPress – Reveal on long press Default: ‘true’ 长按时触发显示
  • swipeAnimationTime – item drop animation time. Default: android configuration 动画时间长度
  • swipeOffsetLeft – left offset 左偏移量
  • swipeOffsetRight – right offset 右偏移量
基本属性都介绍了,下面上例子:
1、布局文件
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/white"
android:clickable="true"
android:orientation="vertical" xmlns:swipe="http://schemas.android.com/apk/res/com.example.zhy_swipelistview02">
<include
layout="@layout/main_title"
android:focusable="true" />
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent" >
<com.fortysevendeg.swipelistview.SwipeListView
android:id="@+id/id_swipelistview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
swipe:swipeActionLeft="reveal"
swipe:swipeBackView="@+id/id_back"
swipe:swipeCloseAllItemsWhenMoveList="true"
swipe:swipeFrontView="@+id/id_front"
swipe:swipeMode="left"
swipe:swipeOffsetLeft="200dip"
swipe:swipeOpenOnLongPress="false" />
<TextView
android:id="@+id/empty"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:drawableTop="@drawable/no_chat"
android:text="木有联系人"
android:textColor="#ffb7b7b7"
android:textSize="14.0sp"
android:visibility="gone" />
</FrameLayout>
<requestFocus />
</LinearLayout>

item的布局文件:

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="60dp" >
<LinearLayout
android:id="@+id/id_back"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#ffcccccc"
android:gravity="center|right" >
<Button
android:id="@+id/id_remove"
android:layout_width="60dp"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_marginRight="4dp"
android:background="@drawable/red_button"
android:text="Delete"
android:textColor="#fff" >
</Button>
</LinearLayout>
<LinearLayout
android:id="@+id/id_front"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#ffffffff" >
<TextView
android:id="@+id/id_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:gravity="center_vertical"
android:minHeight="?android:attr/listPreferredItemHeight"
android:textAppearance="?android:attr/textAppearanceLarge"
android:textColor="#000"
android:textSize="25sp" >
</TextView>
</LinearLayout>
</FrameLayout>

注意对应布局的id和swipeListView中的frontView和backView的Id一致。

2、MainActivity
package com.example.zhy_swipelistview02;
import java.util.ArrayList;
import java.util.List;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.Window;
import com.fortysevendeg.swipelistview.BaseSwipeListViewListener;
import com.fortysevendeg.swipelistview.SwipeListView;
public class MainActivity extends Activity
{
protected static final String TAG = "Activity";
private SwipeListView mSwipeListView;
private DataAdapter mAdapter;
private List<String> mDatas;
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.activity_main);
initDatas();
mSwipeListView = (SwipeListView) findViewById(R.id.id_swipelistview);
mAdapter = new DataAdapter(this, mDatas , mSwipeListView);
mSwipeListView.setAdapter(mAdapter);
mSwipeListView.setSwipeListViewListener(new BaseSwipeListViewListener()
{
@Override
public void onChoiceChanged(int position, boolean selected)
{
Log.d(TAG, "onChoiceChanged:" + position + ", " + selected);
}
@Override
public void onChoiceEnded()
{
Log.d(TAG, "onChoiceEnded");
}
@Override
public void onChoiceStarted()
{
Log.d(TAG, "onChoiceStarted");
}
@Override
public void onClickBackView(int position)
{
Log.d(TAG, "onClickBackView:" + position);
}
@Override
public void onClickFrontView(int position)
{
Log.d(TAG, "onClickFrontView:" + position);
}
@Override
public void onClosed(int position, boolean fromRight)
{
Log.d(TAG, "onClosed:" + position + "," + fromRight);
}
@Override
public void onDismiss(int[] reverseSortedPositions)
{
Log.d(TAG, "onDismiss");
}
@Override
public void onFirstListItem()
{
Log.d(TAG, "onFirstListItem");
}
@Override
public void onLastListItem()
{
Log.d(TAG, "onLastListItem");
}
@Override
public void onListChanged()
{
Log.d(TAG, "onListChanged");
mSwipeListView.closeOpenedItems();
}
@Override
public void onMove(int position, float x)
{
Log.d(TAG, "onMove:" + position + "," + x);
}
@Override
public void onOpened(int position, boolean toRight)
{
Log.d(TAG, "onOpened:" + position + "," + toRight);
}
@Override
public void onStartClose(int position, boolean right)
{
Log.d(TAG, "onStartClose:" + position + "," + right);
}
@Override
public void onStartOpen(int position, int action, boolean right)
{
Log.d(TAG, "onStartOpen:" + position + "," + action + ","
+ right);
}
});
}
private void initDatas()
{
mDatas = new ArrayList<String>();
for (int i = 'A'; i <= 'Z'; i++)
mDatas.add((char) i + "");
}
}

Adapter:

package com.example.zhy_swipelistview02;
import java.util.List;
import com.fortysevendeg.swipelistview.SwipeListView;
import android.content.Context;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.Button;
import android.widget.TextView;
public class DataAdapter extends BaseAdapter
{
private List<String> mDatas;
private LayoutInflater mInflater;
private SwipeListView mSwipeListView ;
public DataAdapter(Context context, List<String> datas , SwipeListView swipeListView)
{
this.mDatas = datas;
mInflater = LayoutInflater.from(context);
mSwipeListView = swipeListView;
}
@Override
public int getCount()
{
return mDatas.size();
}
@Override
public Object getItem(int position)
{
return mDatas.get(position);
}
@Override
public long getItemId(int position)
{
return position;
}
@Override
public View getView(final int position, View convertView, ViewGroup parent)
{
convertView = mInflater.inflate(R.layout.list_item, null);
TextView tv = (TextView) convertView.findViewById(R.id.id_text);
Button del = (Button) convertView.findViewById(R.id.id_remove);
tv.setText(mDatas.get(position));
del.setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View v)
{
mDatas.remove(position);
notifyDataSetChanged();
/**
* 关闭SwipeListView
* 不关闭的话,刚删除位置的item存在问题
* 在监听事件中onListChange中关闭,会出现问题
*/
mSwipeListView.closeOpenedItems();
}
});
return convertView;
}
}

代码相当简单,MainActivity里面设置了监听事件,可以使用Demo的时候,观察触发的事件的输出,如果有特殊需求可以做一些操作。
