【问题描述】：
我对 Android 编程完全陌生，抱歉，如果我问了一个愚蠢的问题。如何在 TextView 的单击上添加日期选择器，然后在选择日期时它应该更新相应的 TextView。我正在制作的表格中有多个日期字段。并且在其他片段中也有许多日期字段。我已经看到了很多答案，但不知道如何应用它。我的意思是哪个代码去哪里。请按步骤向我解释。
更新： 我现在可以膨胀不同 TextView 的 datepicker onclick，但只有一个 TextView 在选择日期时更新，而不是在相应的 TextView 上更新。
XML：
<TextView
android:id="@+id/DateOfEventForm"
android:textSize="15dp"
android:background="@drawable/roundwhite"
android:layout_width="match_parent"
android:layout_height="38dp"
android:layout_gravity="center_horizontal"
android:textColor="@android:color/black" />
<TextView
android:id="@+id/TimeDateOccurence"
android:layout_width="match_parent"
android:textSize="15dp"
android:background="@drawable/roundwhite"
android:layout_height="38dp"
android:layout_gravity="center_horizontal"
android:textColor="@android:color/black" />
这就是活动片段现在的样子
public class FragmentReportAFault extends Fragment {
private View mRootView;
private Button mNextButton, mSaveButton, mDeleteButton;
private LinearLayout mFirstLayoutForm, mSecondLayoutForm;
private TextView mSelectorOne, mSelectorTwo;
private TextView DateOfEventForm,TimeDateOccurence;
int clicked;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
mRootView = inflater.inflate(R.layout.fragment_reportafault, container, false);
uiInitialize();
setListners();
return mRootView;
}
private void uiInitialize() {
mFirstLayoutForm = (LinearLayout) mRootView.findViewById(R.id.FirstLayoutForm);
mSecondLayoutForm = (LinearLayout) mRootView.findViewById(R.id.SecondLayoutForm);
mNextButton = (Button) mRootView.findViewById(R.id.btnNext);

DateOfEventForm= (TextView)mRootView.findViewById(R.id.DateOfEventForm);
TimeDateOccurence= (TextView)mRootView.findViewById(R.id.TimeDateOccurence);
}
private DatePickerDialog.OnDateSetListener dateSetListener = new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
if (clicked == 0) {
DateOfEventForm.setText(year + " -" + (monthOfYear + 1) + "-" + dayOfMonth);
}
else if (clicked == 1){
DateOfEventForm.setText(year + " -" + (monthOfYear + 1) + "-" + dayOfMonth);
}
}
};
private void setListners() {
mNextButton.setOnClickListener(onClick);
mSaveButton.setOnClickListener(onClick);
mDeleteButton.setOnClickListener(onClick);
mFirstLayoutForm.setVisibility(View.VISIBLE);
mSecondLayoutForm.setVisibility(View.GONE);
mSelectorOne.setBackgroundResource(R.drawable.rounded_corner);
mSelectorTwo.setBackgroundResource(R.drawable.rounded_corner_white);
DateOfEventForm.setOnClickListener(onClick);
TimeDateOccurence.setOnClickListener(onClick);
}
View.OnClickListener onClick = new View.OnClickListener() {
@Override
public void onClick(View v) {
switch(v.getId()){
case R.id.btnNext:{
mFirstLayoutForm.setVisibility(View.GONE);
mSecondLayoutForm.setVisibility(View.VISIBLE);
mSelectorOne.setBackgroundResource(R.drawable.rounded_corner);
mSelectorTwo.setBackgroundResource(R.drawable.rounded_corner);
mSelectorTwo.setTextColor(Color.WHITE);
}break;

}break;
case R.id.btnDelete:{
}
break;
case R.id.DateOfEventForm:{
Calendar calendar = Calendar.getInstance();

clicked =0;
DatePickerDialog dateDialog = new DatePickerDialog(getActivity(), dateSetListener, year, month, day);
dateDialog.show();
}
break;
case R.id.TimeDateOccurence:{
Calendar calendar = Calendar.getInstance();
int year = calendar.get(Calendar.YEAR);
int month = calendar.get(Calendar.MONTH);
int day = calendar.get(Calendar.DAY_OF_MONTH);
clicked =1;
DatePickerDialog dateDialog = new DatePickerDialog(getActivity(), dateSetListener, year, month, day);
dateDialog.show();
}
break;
}
}
};}
