SwipeListView 详解 实现微信，QQ等滑动删除效果
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
[html] <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：
[html] <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
[java]
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:
[java]
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。
