我怎麼能叫上單擊可擴展列表視圖子項

我想開發可擴展的應用Listview手機號碼。我有一些Java代碼。但我不知道如何通過點擊Expandable ListView Child Item來調用手機號碼。比如，我想調用的「MD。納西爾·烏丁」手機號碼，「MD。塞利姆汗」，「拉蒂夫Sarker」，「法魯克·艾哈邁德」，「穆尼爾阿克拉姆」。我怎麼能叫上單擊可擴展列表視圖子項

這是我的Java代碼。

public class MainActivity extends Activity implements 
SearchView.OnQueryTextListener, SearchView.OnCloseListener{ 

private SearchView search; 
private MyListAdapter listAdapter; 
private ExpandableListView myList; 
private ArrayList<SectionItem> section = new ArrayList<SectionItem>(); 

ExpandableListView expandableList = null; 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     expandableList=(ExpandableListView)findViewById(R.id.expandableList); 

     SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE); 
     search = (SearchView) findViewById(R.id.search); 
     search.setSearchableInfo(searchManager.getSearchableInfo(getComponentName())); 
     search.setIconifiedByDefault(false); 
     search.setOnQueryTextListener(this); 
     search.setOnCloseListener(this); 

     //display the list 
     displayList(); 
     //expand all Groups 
     expandAll(); 

     } 

     @Override 
     public boolean onCreateOptionsMenu(Menu menu) { 
      getMenuInflater().inflate(R.menu.main, menu); 
      return true; 
     } 

     //method to expand all groups 
    private void expandAll() { 
     int count = listAdapter.getGroupCount(); 
     for (int i = 0; i < count; i++){ 
     myList.expandGroup(i); 
     } 
    } 

    //method to expand all groups 
    private void displayList() { 

     //display the list 
     loadSomeData(); 

     //get reference to the ExpandableListView 
     myList = (ExpandableListView) findViewById(R.id.expandableList); 
     //create the adapter by passing your ArrayList data 
     listAdapter = new MyListAdapter(MainActivity.this, section); 
     //attach the adapter to the list 
     myList.setAdapter(listAdapter); 

    } 

    private void loadSomeData() { 

     ArrayList<EntryItem> items = new ArrayList<EntryItem>(); 

     items = new ArrayList<EntryItem>(); 
     section.add(new SectionItem("Family Member", items)); 
     items.add(new EntryItem(R.drawable.ic_launcher, "Md. Nasir Uddin", "+88569842525", "+6525412698", "[email protected]", ""));

不要標籤的Java代碼的JScript，因爲他們是不一樣的，正確格式化您的代碼，除非你正在使用SOMER DIFF庫，不添加到代碼標準API導入。 –

集點擊收聽到ListView火撥號意圖，這將打開撥號器應用與手機號碼進入

mListView.setOnChildClickListener(new ExpandableListView.OnChildClickListener() { 
    @Override 
    public boolean onChildClick(ExpandableListView parent, View v, int groupPosition, int 
      childPosition, long id) { 
     String number = mAdapter.getChild(groupPosition, childPosition).getMobileNumber(); 
     Intent intent = new Intent(Intent.ACTION_DIAL, Uri.parse("tel:" + number)); 
     startActivity(intent); 
     return true; 
    } 
});

或U可以使用Intent.ACTION_CALL代替Intent.ACTION_DIAL直接撥打該號碼，但是這將需要許可的情況下添加到您的AndroidManifest.xml

謝謝給我示例代碼。但是這條線不起作用。顯示錯誤。字符串數= mAdapter.getChild（groupPosition，childPosition）.getMobileNumber（）; –

變化.getMobileNumber（）來EntryItem對象返回的手機號碼，並mAdapter到listAdapter – Biggemot

我怎樣才能改變.getMobileNumber（）來EntryItem對象返回的手機號碼，並mAdapter到listAdapter方法的方法。請寫出示例代碼 –
