先来看activity_main.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" xmlns:swipe="http://schemas.android.com/apk/res-auto" android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".MainActivity" > <com.fortysevendeg.swipelistview.SwipeListView android:id="@+id/example_lv_list" android:layout_width="match_parent" android:layout_height="match_parent" android:listSelector="#00000000" swipe:swipeActionLeft="dismiss" swipe:swipeActionRight="reveal" swipe:swipeAnimationTime="0" swipe:swipeBackView="@+id/back" swipe:swipeCloseAllItemsWhenMoveList="true" swipe:swipeFrontView="@+id/front" swipe:swipeMode="both" swipe:swipeOffsetLeft="0dp" swipe:swipeOffsetRight="0dp" swipe:swipeOpenOnLongPress="false" /> </RelativeLayout>
这里就一个swipelistview控件,我说几个不易理解的属性
表示滑动时的操作,dismiss表示滑动时删除,如果设置为reveal表示滑动时会显示出item后面的选项
swipe:swipeActionLeft=”dismiss”
swipe:swipeActionRight=”reveal”
这个是背面布局的id(我们把直接看到的布局叫做前面的,滑动之后才能看到的布局叫做背面的),必须与背面布局id对应
swipe:swipeBackView=”@+id/back”
这个是滚动时候是否关闭背面的布局,true表示关闭,false表示不关闭,一般设置为true
swipe:swipeCloseAllItemsWhenMoveList=”true”
这个是前面布局的id,要与布局的id对应
swipe:swipeFrontView=”@+id/front”
both表示可以向左滑也可以向右滑,right和left分别表示只能向有或者向左滑动。
swipe:swipeMode=”both”
下面两个表示向左或者向右滑动时的偏移量,一般不在xml文件中设置,而是在代码中根据设置的大小来设置偏移量。
swipe:swipeOffsetLeft=”0dp”
swipe:swipeOffsetRight=”0dp”
再来看看Item布局文件,这里包括前面的和后面的,两个重叠在一起:
<?xml version="1.0" encoding="utf-8"?> <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" > <!-- linearlayout中的布局是每一项后面隐藏的布局 --> <LinearLayout android:id="@+id/back" android:layout_width="match_parent" android:layout_height="80dp" android:background="#eee" android:tag="back" > <Button android:id="@+id/example_row_b_action_1" android:layout_width="0dp" android:layout_height="60dp" android:layout_gravity="center" android:layout_marginRight="10dp" android:layout_weight="1" android:text="测试" /> <Button android:id="@+id/example_row_b_action_2" android:layout_width="0dp" android:layout_height="60dp" android:layout_gravity="center" android:layout_marginLeft="10dp" android:layout_weight="1" android:text="删除" /> <Button android:id="@+id/example_row_b_action_3" android:layout_width="0dp" android:layout_height="60dp" android:layout_gravity="center" android:layout_weight="1" android:text="编辑" /> </LinearLayout> <!-- 这里是前台显示的布局 --> <RelativeLayout android:id="@+id/front" android:layout_width="match_parent" android:layout_height="80dp" android:background="#ffffff" android:orientation="vertical" android:tag="front" > <TextView android:id="@+id/example_row_tv_title" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_centerInParent="true" android:textSize="18sp" /> </RelativeLayout> </FrameLayout>
这个布局是一个常规布局,我就不解释了。
MainActivity.java,关键地方都有注释
public class MainActivity extends Activity { private SwipeListView mSwipeListView ; private SwipeAdapter mAdapter ; public static int deviceWidth ; private List<String> testData ; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); mSwipeListView = (SwipeListView) findViewById(R.id.example_lv_list); testData = getTestData(); //数据适配 mAdapter = new SwipeAdapter(this, R.layout.package_row, testData,mSwipeListView); //拿到设备宽度 deviceWidth = getDeviceWidth(); mSwipeListView.setAdapter(mAdapter); //设置事件监听 mSwipeListView.setSwipeListViewListener( new TestBaseSwipeListViewListener()); reload(); } private List<String> getTestData() { String [] obj = new String[]{"红楼梦","西游记","水浒传","管锥编","宋诗选注","三国演义","android开发高级编程","红楼梦","西游记","水浒传","管锥编","宋诗选注","三国演义","android开发高级编程"}; List<String> list = new ArrayList<String>(Arrays.asList(obj)); return list; } private int getDeviceWidth() { return getResources().getDisplayMetrics().widthPixels; } private void reload() { // mSwipeListView.setSwipeMode(SwipeListView.SWIPE_MODE_LEFT); // mSwipeListView.setSwipeActionLeft(SwipeListView.SWIPE_ACTION_REVEAL); // mSwipeListView.setSwipeActionRight(settings.getSwipeActionRight()); //滑动时向左偏移量,根据设备的大小来决定偏移量的大小 mSwipeListView.setOffsetLeft(deviceWidth * 1 / 3); mSwipeListView.setOffsetRight(deviceWidth * 1 / 3); // mSwipeListView.setOffsetRight(convertDpToPixel(settings.getSwipeOffsetRight())); //设置动画时间 mSwipeListView.setAnimationTime(30); mSwipeListView.setSwipeOpenOnLongPress(false); } class TestBaseSwipeListViewListener extends BaseSwipeListViewListener{ //点击每一项的响应事件 @Override public void onClickFrontView(int position) { super.onClickFrontView(position); Toast.makeText(getApplicationContext(), testData.get(position), Toast.LENGTH_SHORT).show(); } //关闭事件 @Override public void onDismiss(int[] reverseSortedPositions) { for (int position : reverseSortedPositions) { Log.i("lenve", "position--:"+position); testData.remove(position); } mAdapter.notifyDataSetChanged(); } } }
数据适配器:
public class SwipeAdapter extends ArrayAdapter<String> { private LayoutInflater mInflater ; private List<String> objects ; private SwipeListView mSwipeListView ; public SwipeAdapter(Context context, int textViewResourceId,List<String> objects, SwipeListView mSwipeListView) { super(context, textViewResourceId, objects); this.objects = objects ; this.mSwipeListView = mSwipeListView ; mInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); } @Override public View getView(final int position, View convertView, ViewGroup parent) { ViewHolder holder = null ; if(convertView == null){ convertView = mInflater.inflate(R.layout.package_row, parent, false); holder = new ViewHolder(); holder.mFrontText = (TextView) convertView.findViewById(R.id.example_row_tv_title); holder.mBackEdit = (Button) convertView.findViewById(R.id.example_row_b_action_3); holder.mBackDelete = (Button) convertView.findViewById(R.id.example_row_b_action_2); convertView.setTag(holder); }else{ holder = (ViewHolder) convertView.getTag(); } holder.mBackDelete.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { //关闭动画 mSwipeListView.closeAnimate(position); //调用dismiss方法删除该项(这个方法在MainActivity中) mSwipeListView.dismiss(position); } }); String item = getItem(position); holder.mFrontText.setText(item); return convertView; } class ViewHolder{ TextView mFrontText ; Button mBackEdit,mBackDelete ; } }
