使用swipelistview向左滑动不动

Posted 2023-02-19

本例子实现了滑动删除ListView的Itemdemo的效果、大家都知道、这种创意是来源于ios的、左滑删除的功能、在android上面实现比较麻烦、本例子中不仅实现了左滑删除功能、还实现了左滑赞、左滑分享、左滑收藏等功能、当然大家也可以根据自己项目的需求来修改功能、且在左滑的时候还配有简单的滑动动画呢、非常不错、下面一起来看看实现过程吧
初始化代码
@Override
protected void onCreate(Bundle savedInstanceState)
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_list);

mAppList = getPackageManager().getInstalledApplications(0);

mListView = (SwipeMenuListView) findViewById(R.id.listView);
mAdapter = new AppAdapter();
mListView.setAdapter(mAdapter);

// step 1. create a MenuCreator
SwipeMenuCreator creator = new SwipeMenuCreator()

@Override
public void create(SwipeMenu menu)
// create "open" item
SwipeMenuItem openItem = new SwipeMenuItem(
getApplicationContext());
// set item background
openItem.setBackground(new ColorDrawable(Color.rgb(0xC9, 0xC9,
0xCE)));
// set item width
openItem.setWidth(dp2px(90));
// set item title
openItem.setTitle("Open");
// set item title fontsize
openItem.setTitleSize(18);
// set item title font color
openItem.setTitleColor(Color.WHITE);
// add to menu
menu.addMenuItem(openItem);

// create "delete" item
SwipeMenuItem deleteItem = new SwipeMenuItem(
getApplicationContext());
// set item background
deleteItem.setBackground(new ColorDrawable(Color.rgb(0xF9,
0x3F, 0x25)));
// set item width
deleteItem.setWidth(dp2px(90));
// set a icon
deleteItem.setIcon(R.drawable.ic_delete);
// add to menu
menu.addMenuItem(deleteItem);

;
// set creator
mListView.setMenuCreator(creator);


绑定左滑和删除事件
// step 2. listener item click event
mListView.setOnMenuItemClickListener(new
OnMenuItemClickListener()
@Override
public void onMenuItemClick(int position,
SwipeMenu menu, int index)
ApplicationInfo item = mAppList.get(position);
switch (index)
case 0:
// open
open(item);
break;
case 1:
// delete
//delete(item);
mAppList.remove(position);
mAdapter.notifyDataSetChanged();
break;


);

// set SwipeListener
mListView.setOnSwipeListener(new OnSwipeListener()

@Override
public void onSwipeStart(int position)
// swipe start


@Override
public void onSwipeEnd(int position)
// swipe end

);

// other setting
//listView.setCloseInterpolator(new BounceInterpolator());

// test item long click
mListView.setOnItemLongClickListener(new
OnItemLongClickListener()

@Override
public boolean onItemLongClick(AdapterView<?> parent,
View view,
int position, long id)
Toast.makeText(getApplicationContext(),
position " long click", 0).show();
return false;

); 参考技术A 以android-swipelistview的开源项目为例。

android-swipelistview项目分两个部分：

1.lib是:android-swipelistview；

2.例子是:SwipeListViewExampleActivity。

进入正题：

android-swipelistview:

1. 引入android-swipelistview库：导入开源库，用Import选项，然后Android选项下的“Existing Android Code Into Workspace”引入库；

2.引入android-swipelistview的依赖库nineoldandroids-2.4.0.jar：项目的Properties选项，Java Build Path标签，Libraries标签，Add External JARs按钮导入nineoldandroids-2.4.0.jar包；

3.引入android-swipelistview的依赖内部库android-support-v4.jar：项目的Android Tools选项，“Add Support Library”来增加android-support-v4库；（注：如果找不到对应的support库，可以通过SDK Manager来进行下载）

4.编译android-swipelistview库的jar包：项目的Properties选项，Android选项，勾选"Is Library"；

5.编译android-swipelistview项目，在项目的bin目录应该能看到android-swipelistview.jar包。

SwipeListViewExampleActivity：

6.引入android-swipelistview.jar包：项目的Properties选项，Android选项，Library框选择add按钮添加android-swipelistview.jar包；

7.同第3步一样引入android-support-v4库；

8.打包前要包含android-support-v4库：项目的Properties选项，Java Build Path标签，Order and Export选项，勾选“Android Private Libraries”选项；

9.编译SwipeListViewExampleActivity项目。（注：更改配置项可能不会重新编译，所以需要手动clean，否则可能会出现一些莫名其妙的错误，本人就吃了大亏，请大家牢记）本回答被提问者采纳
