Question

I used the below code for displaying all cities time. When i execute my code the time will displayed in a list view, now my problem is once i click any one of the country (position in list), i must pass the Country name, day, month, year and time from the list to another class (*ShowAnalogClock)*. In ShowAnalogClock class i will display the time which is fetched from the list view.

main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <AutoCompleteTextView
        android:id="@+id/autoCompleteZone"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:completionThreshold="1" >

        <requestFocus />
    </AutoCompleteTextView>

    <ListView
        android:id="@+id/zoneList"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content" >
    </ListView>

    <TextView
        android:id="@+id/autoCompleteTextview"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Medium Text"
        android:textAppearance="?android:attr/textAppearanceMedium" />

</LinearLayout>

timezone.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="?android:attr/listPreferredItemHeight"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/timezone_name"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:textSize="25dip" />

    <TextView
        android:id="@+id/timezone_time"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:textSize="15dip" />

</LinearLayout>

My Java code is,

TimeZoneProjectActivity.java

package com.test.timezone;

import java.text.SimpleDateFormat;
import java.util.ArrayList;
import java.util.Date;
import java.util.List;
import java.util.TimeZone;

import android.app.Activity;

import android.widget.TextView;
import android.widget.Toast;

public class TimeZoneProjectActivity extends Activity {
    /** Called when the activity is first created. */
    ListView ZONE_LIST;
    AutoCompleteTextView zoneComplete_TXT;
    TimeZoneAdaptor timezoneAdaptor;
    List<TimeZoneDataList> timezonelist;
    String[] listItems;
    TextView auto_completeTXT;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        auto_completeTXT = (TextView) findViewById(R.id.autoCompleteTextview);
        ZONE_LIST = (ListView) findViewById(R.id.zoneList);
        zoneComplete_TXT = (AutoCompleteTextView) findViewById(R.id.autoCompleteZone);
        timezonelist = new ArrayList<TimeZoneDataList>();
        timezoneAdaptor = new TimeZoneAdaptor(this, R.layout.timezoneview,
                timezonelist);

        ZONE_LIST.setAdapter(timezoneAdaptor);

        ZONE_LIST.setOnItemClickListener(new OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView<?> parent, View v,
                    int position, long arg3) {
                // TODO Auto-generated method stub
                //

                System.out.println("Clicked Position" + position);
            }
        });
    }

    @Override
    protected void onStart() {
        super.onStart();

        listItems = TimeZone.getAvailableIDs();
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
                android.R.layout.simple_dropdown_item_1line, listItems);
        zoneComplete_TXT.setAdapter(adapter);

        TimeZone timezone = null;
        SimpleDateFormat format = new SimpleDateFormat(
                "EEE, MMM d, yyyy h:mm a");
        Date now = new Date();

        for (int index = 0; index < listItems.length; ++index) {
            timezone = TimeZone.getTimeZone(listItems[index]);

            format.setTimeZone(timezone);

            timezonelist.add(new TimeZoneDataList(
                    getDiaplayName(listItems[index]), format.format(now)));

            timezone = null;
        }
    }

    private String getDiaplayName(String timezonename) {
        String displayname = timezonename;
        int sep = timezonename.indexOf('/');

        if (-1 != sep) {
            displayname = timezonename.substring(0, sep) + ", "
                    + timezonename.substring(sep + 1);
            displayname = displayname.replace("_", " ");
        }

        return displayname;
    }

    public class TimeZoneAdaptor extends ArrayAdapter<TimeZoneDataList> {

        List<TimeZoneDataList> objects = null;

        public TimeZoneAdaptor(Context context, int textViewResourceId,
                List<TimeZoneDataList> objects) {
            super(context, textViewResourceId, objects);

            this.objects = objects;
        }

        @Override
        public int getCount() {
            return ((null != objects) ? objects.size() : 0);
        }

        @Override
        public TimeZoneDataList getItem(int position) {
            return ((null != objects) ? objects.get(position) : null);
        }

        @Override
        public long getItemId(int position) {
            return position;
        }

        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
            View view = convertView;

            if (null == view) {
                LayoutInflater vi = (LayoutInflater) TimeZoneProjectActivity.this
                        .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
                view = vi.inflate(R.layout.timezoneview, null);
            }

            TimeZoneDataList data = objects.get(position);

            if (null != data) {
                TextView textName = (TextView) view
                        .findViewById(R.id.timezone_name);
                TextView textTime = (TextView) view
                        .findViewById(R.id.timezone_time);

                textName.setText(data.name);
                textTime.setText(data.time);
            }

            return view;
        }
    }
}

TimeZoneDataList.java

package com.test.timezone;

public class TimeZoneDataList {
    public String name;
    public String time;

    public TimeZoneDataList(String name, String time) {
        this.name = name;
        this.time = time;
    }
}

In which code i will add in the following block, to pass the listview content

ZONE_LIST.setOnItemClickListener(new OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView<?> parent, View v,
                    int position, long arg3) {
                // TODO Auto-generated method stub

                System.out.println("Clicked Position" + position);
            }
        });

Answer 1

You can only pass primitives and Parcelable objects between Activities. It should be pretty easy to make a class which encapsulates your primitives and implements the Parcelable interface. You can then pass this class in the Extras bundle of the Intent.

Or you can just pass your primitives directly, also in the Intent Extras.
