android分享选项列表视图项目

Question

我想共享列表视图items.Listview包含许多items.But当我选择第三或任何项目以外的第一个项目共享，它只采取第一个项目共享。我有附上我的代码。请帮我解决这个问题。

public boolean onActionItemClicked(ActionMode mode, MenuItem item) { 
    switch (item.getItemId()) { 
    case R.id.share: 
     SparseBooleanArray selectedshare = adapter.getSelectedIds(); 
     for (int i = (selectedshare.size() - 1); i >= 0; i--) { 
      if (selectedshare.valueAt(i)) { 

       val = list.get(i).getId(); 
       System.out.println("idddddddddd"+val); 
       date = list.get(i).getDate(); 
       System.out.println("dateeee"+date); 
       title = list.get(i).getTitle(); 
       System.out.println("titleeee"+title); 
       content = list.get(i).getContent(); 
       System.out.println("contenttttt"+content); 

       shareIt(); 

      } 
     } 
     return true; 
     ///////for sharing/////// 
     default: 
     return false; 
    } 
} 





////here is the function////// 

private void shareIt() { 
//sharing implementation here 
    Intent sharingIntent = new Intent(android.content.Intent.ACTION_SEND); 
    sharingIntent.setType("text/plain"); 
    sharingIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "All memories"); 
    sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, "Date :"+date +"\n"+"Title :"+title+"\n"+"Content :"+ content); 
    startActivity(Intent.createChooser(sharingIntent, "Share via")); 
} 

@Override 
public boolean onOptionsItemSelected(MenuItem item) { 
    // Handle action bar item clicks here. The action bar will 
    // automatically handle clicks on the Home/Up button, so long 
    // as you specify a parent activity in AndroidManifest.xml. 
    int id = item.getItemId(); 

    //noinspection SimplifiableIfStatement 
    if (id == R.id.action_settings) { 
     return true; 
    } 

    return super.onOptionsItemSelected(item); 
} 

这里是我的适配器代码： 我做的适配器类没有共享。

public class ListViewAdapter extends BaseAdapter { 

public ArrayList<all_memories_getter_setter>list; 
Activity activity; 

/////**///// multiple delete 
private SparseBooleanArray mSelectedItemsIds; 

public ListViewAdapter(Activity activity, 
ArrayList<all_memories_getter_setter>list) 
{ 
    super(); 
    mSelectedItemsIds= new SparseBooleanArray(); 
    this.activity=activity; 
    this.list=list; 
} 

@Override 
public int getCount() { 
    return list.size(); 
} 

@Override 
public Object getItem(int position) { 
    return list.get(position); 
} 

@Override 
public long getItemId(int position) { 
    return 0; 
} 

/////**/////// for multiple delete 
public void remove(all_memories_getter_setter object){ 
    list.remove(object); 
    notifyDataSetChanged(); 
} 

public List<all_memories_getter_setter> getall_memories_getter_setter(){ 
    return list; 
} 

public void toggleSelection(int position){ 
    selectView(position, !mSelectedItemsIds.get(position)); 

} 
public void removeSelection(){ 
    mSelectedItemsIds = new SparseBooleanArray(); 
    notifyDataSetChanged(); 
} 

public void selectView(int position , boolean value){ 
    if(value){ 
     mSelectedItemsIds.put(position, value); 
    }else{ 
     mSelectedItemsIds.delete(position); 
     notifyDataSetChanged(); 
    } 

} 
public int getSelectedCount(){ 
    return mSelectedItemsIds.size(); 
} 
public SparseBooleanArray getSelectedIds(){ 
    return mSelectedItemsIds; 
} 

public class Viewholder 
{ 
    TextView txtFirst; 
    TextView txtSecond; 
    TextView txtThird; 
} 
@Override 
public View getView(int position, View convertView, ViewGroup parent) { 
    Viewholder holder; 
    LayoutInflater inflater = activity.getLayoutInflater(); 
    if (convertView == null) { 
     convertView = 
inflater.inflate(R.layout.activity_all_memories_listview, null); 
     holder = new Viewholder(); 
     holder.txtFirst = (TextView) 
convertView.findViewById(R.id.list_date); 
     holder.txtSecond = (TextView) 
convertView.findViewById(R.id.list_title); 
     holder.txtThird = (TextView) 
convertView.findViewById(R.id.list_content); 
     convertView.setTag(holder); 

    } else { 
     holder = (Viewholder) convertView.getTag(); 
    } 

    holder.txtFirst.setText("" + list.get(position).getDate()); 
    holder.txtSecond.setText("" + list.get(position).getTitle()); 
    holder.txtThird.setText("" + list.get(position).getContent()); 
    return convertView; 
} 

}

请按照以下步骤将内容分享到其他应用或应用 内，你可以写ListviewAdapter类的getview（）方法中你自己的方法

防爆ListView的项目：

public class ListViewTestFiveActivity extends Activity{ 

private ListView listView; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_list_view_test_five); 


    init(); 
} 

private void init() { 
    listView = (ListView)findViewById(R.id.ListViewTestFiveActivity_listView); 
    ArrayList<Item> items = new ArrayList<>(); 

    for (int i = 0; i < 15; i++) { 
     Item item = new Item(); 
     item.setCount(i); 
     items.add(item); 
    } 

    MyAdapter adapter = new MyAdapter(getApplicationContext(), R.layout.single_item_listview_five, items); 
    listView.setAdapter(adapter); 
} 

private class MyAdapter extends ArrayAdapter{ 

    private ArrayList<Item> items; 
    private Context a_context; 
    private LayoutInflater a_layoutInflater; 

    public MyAdapter(Context context, int resource, ArrayList<Item> items) { 
     super(context, resource, items); 
     this.a_context = context; 
     this.items = items; 
     a_layoutInflater = LayoutInflater.from(this.a_context); 
    } 


    @Override 
    public View getView(int position, View convertView, ViewGroup parent) { 
     View row = convertView; 
     ViewHolder holder = null; 
     if (row == null) { 
      row = a_layoutInflater.inflate(R.layout.single_item_listview_five, parent, false); 
      holder = new ViewHolder(); 
      holder.share = (Button) row.findViewById(R.id.ListViewTestFiveActivity_share_button); 

      row.setTag(holder); 
     } else { 
      holder = (ViewHolder) row.getTag(); 
     } 

     final Item item = items.get(position); 
     holder.share.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       //Here you can write your own code to share the data, item has the data which you want to share 
      } 
     }); 

     return row; 
    } 

    private class ViewHolder{ 
     Button share; 

    } 
} 

private class Item { 
    int count; 

    public int getCount() { 
     return count; 
    } 

    public void setCount(int count) { 
     this.count = count; 
    } 


    } 
} 

让我知道它是否适用于您
