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。
