Building a Mobile Employee Directory – Step 4: Pass data to DetailActivity to display more data and provide other functionality (w/ intent.putExtra)
Continuing with the mobile employee directory example, I’ve added the detail activity.
MainActivity.java
package com.himebaugh.employeedirectory;
import java.util.List;
import android.app.ListActivity;
import android.content.Intent;
import android.database.Cursor;
import android.os.AsyncTask;
import android.os.Bundle;
import android.support.v4.widget.SimpleCursorAdapter;
import android.view.Menu;
import android.view.View;
import android.widget.ListView;
import android.widget.TextView;
// GOAL: Build a native android Mobile Employee Directory
// ** The result is similar to the sample with Flex and Flash Builder
// see http://www.adobe.com/devnet/flex/articles/employee-directory-android-flex.html
// PURPOSE: Learning how to build an Android App.
// Step 4: Pass data to DetailActivity to display more data and provide other functionality (w/ intent.putExtra)
// 1) Create DetailActivity
// 2) Create activity_detail.xml (in res/layout)
// 3) Add DetailActivity to AndroidManifest.xml
// 4) Add uses-permissions to AndroidManifest.xml
// 5) Modify strings.xml (in res/values)
// 6) Create mail.png, phone.png, sms.png (in res/drawable)
// 7) Create employee_photo.jpg (in assets/pics)
