我有一个主要活动，其中包含完美运作的日期选择器我想将主活动中选择的日期发送到第二个活动，这个活动基本上只是通过获取意图如何在代码下面进行itred但它没有工作

主要活动

package com.Blog.blogname;

import java.util.Calendar;
import java.util.StringTokenizer;

//import org.example.androidsdk.demo.DetailActivity;
//import org.example.androidsdk.demo.MainActivity;

import android.app.Activity;
import android.app.DatePickerDialog;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.DatePicker;
import android.widget.EditText;

public class Datepicker extends Activity {
private EditText txtView;
private String initialDate;
private String initialMonth;
private String initialYear;
private DatePickerDialog dialog = null;
Context context;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.datepicker);
    Button btn = (Button) findViewById(R.id.button1);
    txtView = (EditText) findViewById(R.id.textView1);
    context = getApplicationContext();
    btn.setOnClickListener(new View.OnClickListener() {

        @SuppressWarnings("deprecation")
        @Override
        public void onClick(View v) {
            Calendar dtTxt = null;

          String preExistingDate = (String) txtView.getText().toString();

          if(preExistingDate != null && !preExistingDate.equals("")){
              StringTokenizer st = new StringTokenizer(preExistingDate,"/");
                  initialMonth = st.nextToken();
                  initialDate = st.nextToken();
                  initialYear = st.nextToken();
                  if(dialog == null)
                  dialog = new DatePickerDialog(v.getContext(),
                                   new PickDate(),Integer.parseInt(initialYear),
                                   Integer.parseInt(initialMonth),
                                   Integer.parseInt(initialDate));
                  dialog.updateDate(Integer.parseInt(initialYear),
                                   Integer.parseInt(initialMonth),
                                   Integer.parseInt(initialDate));

          } else {
              dtTxt = Calendar.getInstance();
              if(dialog == null)
              dialog = new DatePickerDialog(v.getContext(),new PickDate(),dtTxt.getTime().getYear(),dtTxt.getTime().getMonth(),
                                                  dtTxt.getTime().getDay());
              dialog.updateDate(dtTxt.getTime().getYear(),dtTxt.getTime().getMonth(),
                                                  dtTxt.getTime().getDay());
          }

            dialog.show();
        }

    });
}
private class PickDate implements DatePickerDialog.OnDateSetListener {

    @Override
    public void onDateSet(DatePicker view, int year, int monthOfYear,
            int dayOfMonth) {

        int monthOfYear1 = monthOfYear + 1;
        String formattedMonth = "" + monthOfYear1;
        String formattedDayOfMonth = "" + dayOfMonth;

        if(monthOfYear1 < 10){

            formattedMonth = "0" + monthOfYear1;
        }
        if(dayOfMonth < 10){

            formattedDayOfMonth = "0" + dayOfMonth;
        }


       // view.updateDate(year, monthOfYear, dayOfMonth);
       // txtView.setText(year+"/"+monthOfYear+"/"+dayOfMonth);

         //view.updateDate(year, formattedMonth, formattedDayOfMonth);
        txtView.setText(year+"-"+formattedMonth+"-"+formattedDayOfMonth);

         Intent intent = new Intent(Datepicker.this, SplashActivityDatewiseCurrentAffairs.class);
         intent.putExtra("Date", year+"-"+formattedMonth+"-"+formattedDayOfMonth);  
        dialog.hide();
    }

}
}

第二项活动

Intent i = getIntent();
String Date = i.getStringExtra("Date");

Answer 1

我想你忘了打电话给startActivity（意图）

将datepicker中的日期从一个活动传递到另一个活动
