我正在使用导航抽屉开发一个应用程序。我的基本活动是仪表板活动。这是一个导航列表。当我点击导航列表中的项目时，它会显示一些使用片段的界面（替换Dashboard Activity）。在AddPatient片段中，我正在显示form.I正在添加Date_of_birth字段，当我点击该date_of_birth时（编辑） -text）查看日期选择器对话框应弹出（使背景透明但黑暗），获取输入，将其显示在片段上。
问题是我没有找到如何在片段上显示日期选择器，基本活动（仪表板活动）扩展了片段活动，而AddPatient片段扩展了DailogFragment。代码如下。我不知道我哪里出错了。
我的仪表板活动的代码是
public class DashboardActivity extends FragmentActivity {
Fragment fragment;
private DrawerLayout mDrawerLayout;
private ExpandableListView mDrawerList;
private ArrayList<NavDrawerItem> navDrawerItems;
private int groupP, childP;
private SwipeListView swipeListView;
List<CalenderDrawable> list;
List<String> menu_items;
Map<String, List<String>> childCollection;
public static List<String> childList;
public static List<String> childListForConnectedService;
private ActionBarDrawerToggle mDrawerToggle;
Session session;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getWindow().requestFeature(Window.FEATURE_ACTION_BAR_OVERLAY);
setContentView(R.layout.activity_dashboard);
session = new Session(this);
fragment = new DashboardFragment();
getFragmentManager().beginTransaction()
.replace(R.id.frame_container, fragment).commit();
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerList = (ExpandableListView) findViewById(R.id.list_slidermenu);
createMenuItemList();
createCollection();
final ExpandableListAdapterNew adapter = new ExpandableListAdapterNew(
DashboardActivity.this, menu_items, childCollection);
mDrawerList.setAdapter(adapter);
getActionBar().setDisplayHomeAsUpEnabled(true);
// getActionBar().setHomeButtonEnabled(true);
getActionBar().setDisplayShowTitleEnabled(false);
getActionBar().setBackgroundDrawable(
new ColorDrawable(Color.parseColor("#33ffffff")));
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
R.drawable.ic_drawer, R.string.empty, R.string.empty) {
public void onDrawerClosed(View view) {
invalidateOptionsMenu(); // Setting, Refresh and Rate App
}
public void onDrawerOpened(View drawerView) {
invalidateOptionsMenu();
}
};
mDrawerLayout.setDrawerListener(mDrawerToggle);
mDrawerList.setOnGroupExpandListener(new OnGroupExpandListener() {
int previousGroup = -1;
@Override
public void onGroupExpand(int groupPosition) {
Toast.makeText(getApplicationContext(),
menu_items.get(groupPosition) + " Expanded",
Toast.LENGTH_SHORT).show();
if (groupPosition != previousGroup)
mDrawerList.collapseGroup(previousGroup);
previousGroup = groupPosition;
}
});
mDrawerList.setOnChildClickListener(new OnChildClickListener() {
@Override
public boolean onChildClick(ExpandableListView parent, View v,
int groupPosition, int childPosition, long id) {
// TODO Auto-generated method stub
Toast.makeText(
getApplicationContext(),
menu_items.get(groupPosition)
+ " : "
+ childCollection.get(
menu_items.get(groupPosition)).get(
childPosition), Toast.LENGTH_SHORT)
.show();
groupP = groupPosition;
childP = childPosition;
switch (groupPosition) {
case 0:
switch (childPosition) {
case 0:
Log.d("CASE Patient ", "Add Patient");
fragment = new AddPatient();
getFragmentManager().beginTransaction()
.replace(R.id.frame_container, fragment)
.commit();
break;
case 1:
Log.d("CASE Patient ", "View Patient");
fragment = new DashboardFragment();
getFragmentManager().beginTransaction()
.replace(R.id.frame_container, fragment)
.commit();
break;
default:
break;
}
mDrawerLayout.closeDrawer(mDrawerList);
return false;
}
});
}
添加患者分数的代码将显示日期选择器是这个..
public class AddPatient extends Fragment implements OnClickListener {
View rootView;
private EditText edtGender, edtUsername, edtMobNo, edtFname, edtLname;
private static TextView edtDOB;
private TextView Heading, textWelcm;

使用
DialogFragment picker = new AddPatient();
picker.show(getFragmentManager(), "datePicker");
