我想在活动中的CardView上单击显示片段，但片段出现在活动中的所有CardView后面。以下是代码：

我在activity_five_designers.xml中包含了片段的FrameLayout。但片段出现在所有的卡片视图后面。我想只显示活动导航抽屉的片段。任何帮助都将不胜感激。

尝试使用此布局：
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"

tools:openDrawer="start">
<include

android:layout_width="match_parent"
android:layout_height="match_parent" >
</include>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/fragment_container"

您需要在工具栏下方声明框架布局才能看到工具栏
public class DateandTimePickerDialogueFragment extends DialogFragment {
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return super.onCreateView(inflater, container, savedInstanceState);
}
@NonNull
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
return displayDateDialogPicker(getActivity());
}
/**
* @param context
*/
private Dialog displayDateDialogPicker(Context context) {
int mYear, mMonth, mDay;
final Calendar c = Calendar.getInstance();
mYear = c.get(Calendar.YEAR);
mMonth = c.get(Calendar.MONTH);
mDay = c.get(Calendar.DAY_OF_MONTH);
DatePickerDialog dpd = new DatePickerDialog(context,
new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year,
int monthOfYear, int dayOfMonth) {
int mymonth = monthOfYear + 1;
String mmmMonth = "", mmDate = "";
if (mymonth > 0 && mymonth < 10) {
mmmMonth = "0" + mymonth;
} else {
mmmMonth = "" + mymonth;
}
if (dayOfMonth > 0 && dayOfMonth < 10) {
mmDate = "0" + dayOfMonth;
} else {
mmDate = "" + dayOfMonth;
}
//YYYY-MM-DD
String finalDate = year + "-" + (mmmMonth) + "-" + mmDate;
Intent intentData = new Intent();
intentData.putExtra("Date", finalDate);
getTargetFragment().onActivityResult(getTargetRequestCode(), Activity.RESULT_OK, intentData);
}
}, mYear, mMonth, mDay);
dpd.show();
return dpd;
}
}
