嘗試下面的代碼，它可以幫助你。

public class ActionModeDemo extends ListActivity { 
private static final String[] items= 
    { "lorem", "ipsum", "dolor", "sit", "amet", "consectetuer", 
     "adipiscing", "elit", "morbi", "vel", "ligula", "vitae", 
     "arcu", "aliquet", "mollis", "etiam", "vel", "erat", 
     "placerat", "ante", "porttitor", "sodales", "pellentesque", 
     "augue", "purus" };

                   getListView())); 
    } 
else { 
    getListView().setChoiceMode(ListView.CHOICE_MODE_MULTIPLE); 
    registerForContextMenu(getListView());

我想你想的出左側角球，CheckBox的ImageView並且在每行一個TextView一個ListView。如果是這樣的話，那麼...不，你不能使用simple_list_item_multiple_choice。您將不得不使用BaseAdapter來實現此目的。 爲了您的需求，你可以調整example你已經使用並添加 ImageView，CheckBox和TextView對XML的每一行中ListView和使用LayoutInflater

Answer 4

下面試試這個填充它們在適配器的getView()代碼片段。

Activity_name.this.runOnUiThread(new Runnable() { 

    @Override 
    public void run() { 
    list = (ArrayList<Map<String, String>>) result; 
    this.adapter.setList(list); 
    this.adapter.notifyDataSetChanged(); 
} 
});
