Java 如何在单击可展开列表视图子项时拨打手机号码

我想开发可扩展的

Listview

应用程序。我有一些Java代码。但我不知道如何在单击可扩展列表视图子项时拨打手机号码。例如，我想拨打“纳西尔·乌丁博士”、“塞利姆·汗博士”、“拉蒂夫·萨克”、“法鲁克·艾哈迈德”、“莫尼尔·阿克兰”的手机号码

这是我的Java代码。

 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", "nasir256@gmail.com", ""));

        items = new ArrayList<EntryItem>();
        section.add(new SectionItem("Relative List", items));
        items.add(new EntryItem(R.drawable.ic_launcher, "Monir Akram", "+2536974144", "+2514796352", "monir25@gmail.com", ""));

     }

     @Override
     public boolean onClose() {
      listAdapter.filterData("");
      expandAll();
      return false;
     }

     @Override
     public boolean onQueryTextChange(String query) {
      listAdapter.filterData(query);
      expandAll();
      return false;
     }

     @Override
     public boolean onQueryTextSubmit(String query) {
      listAdapter.filterData(query);
      expandAll();
      return false;
     }
}

将click listener设置为listview以激发拨号意图，这将打开带有输入手机号码的拨号器应用程序

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;
    }
});

或者您可以使用Intent.ACTION\u CALL而不是Intent.ACTION\u拨号直接拨打电话，但这需要将权限添加到您的AndroidManifest.xml

不要将java代码标记为jscript，因为它们不相同，请正确格式化您的代码，除非您使用somer diff libs，不要添加标准API导入的代码。谢谢你给我示例代码。但是这条线不行。显示错误。String number=mAdapter.getChild（groupPosition，childPosition）.getMobileNumber（）；将.getMobileNumber（）更改为返回手机号码的EntryItem对象的方法，并将其设置为listAdapter如何更改.getMobileNumber（）更改为返回手机号码的EntryItem对象的方法，并将其设置为listAdapter。请编写示例代码
