本示例实现了人欢迎页跳转,拨号、发送短信及长按出现菜单选项的操作

1.Android项目结构图，主要操作红框内的文件

2.布局代码如下

a. activity_main.xml 文件实现的的欢迎界面的布局

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">
    <TextView 
        android:text="android班制作"
        android:background="@drawable/dayday"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        style="@style/basiz"
        android:gravity="center"/>

</LinearLayout>

b. jump.xml文件案例的主要布局界面，listview的布局显示

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >
    <TextView 
        android:id="@+id/jumptv"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Oh My God"
        android:textColor="#f65"
        android:textSize="30dp"
        android:gravity="center"/>
    <ListView
        android:id="@+id/lv"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1" >
    </ListView>

</LinearLayout>

c. list_item.xml 文件 listitem的布局

<?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="wrap_content"
    android:orientation="horizontal" >

    <ImageView
        android:id="@+id/imgview"
        android:layout_width="100dp"
        android:layout_height="100dp"
        android:layout_centerVertical="true"
        android:layout_marginLeft="5px"
        android:layout_marginRight="5px" />

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical" >

        <TextView
            android:id="@+id/tv1"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:text="姓名："
            android:textSize="35px" />

        

        <TextView
            android:id="@+id/tv2"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:text="电话"
            android:textSize="35px" />

        
    </LinearLayout>

</LinearLayout>

3.menu上下文菜单控制文件

<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    tools:context="com.example.kaoshi.MainActivity" >

    <item
        android:id="@+id/item1"
        android:title="拨号">
    </item>
    <item
        android:id="@+id/item2"
        android:title="信息">
    </item>

</menu>

4.java代码实现主要功能

a. MainActivity.java 文件实现欢迎界面到主界面的跳转

package com.example.kaoshi;

import java.util.Timer;
import java.util.TimerTask;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;

public class MainActivity extends Activity {

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);

		final Intent intent = new Intent();
		Timer timer = new Timer();
		TimerTask task = new TimerTask() {

			@Override
			public void run() {
				// TODO Auto-generated method stub
				intent.setClass(MainActivity.this, jump.class);
				MainActivity.this.startActivity(intent);
			}
		};
		timer.schedule(task, 1000*3);
	}
}

b. jump.java 文件该文件实现了主要的功能

/**
 * 
 */
package com.example.kaoshi;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.ContextMenu;
import android.view.ContextMenu.ContextMenuInfo;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemLongClickListener;
import android.widget.ListView;
import android.widget.SimpleAdapter;
import android.widget.TextView;
import android.widget.Toast;

/**
 * @author 张
 * 
 */
public class jump extends Activity {
	private static final Uri SMSToUri = null;
	private ListView lv;
	private TextView tv1, tv2;
	private List<Map<String, Object>> list;
	String xm1 = "";
	String dh1 = "";

	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.jump);
		tv1 = (TextView) findViewById(R.id.tv1);
		tv2 = (TextView) findViewById(R.id.tv2);
		lv = (ListView) findViewById(R.id.lv);
		SimpleAdapter adapter = new SimpleAdapter(this, getData(),
				R.layout.list_item, new String[] { "imgview", "tv1", "tv2" },
				new int[] { R.id.imgview, R.id.tv1, R.id.tv2 });
		// setListAdapter(adapter);
		lv.setAdapter(adapter);
		registerForContextMenu(lv);
		//长按获取listview中的数据 实现拨号
		lv.setOnItemLongClickListener(new OnItemLongClickListener() {

			@Override
			public boolean onItemLongClick(AdapterView<?> arg0, View arg1,
					int arg2, long arg3) {
				// TODO Auto-generated method stub
				HashMap<String, Object> map = (HashMap<String, Object>) lv
						.getItemAtPosition(arg2);
				xm1 = String.valueOf(map.get("tv1").toString());
				dh1 = String.valueOf(map.get("tv2").toString());

				System.out.println(tv1);
				System.out.println(tv2);
				return false;
			}
		});

	}

	private List<? extends Map<String, ?>> getData() {
		// TODO Auto-generated method stub
		List<Map<String, Object>> list = new ArrayList<Map<String, Object>>();
		Map<String, Object> map = new HashMap<String, Object>();
		map.put("imgview", R.drawable.zpyzpy);
		map.put("tv1", "张");
		map.put("tv2", "17853496522");
		list.add(map);

		map = new HashMap<String, Object>();
		map.put("imgview", R.drawable.hyf);
		map.put("tv1", "韩");
		map.put("tv2", "17853496714");
		list.add(map);

		map = new HashMap<String, Object>();
		map.put("imgview", R.drawable.lk);
		map.put("tv1", "鹿");
		map.put("tv2", "15275710175");
		list.add(map);
		map = new HashMap<String, Object>();
		map.put("imgview", R.drawable.qym);
		map.put("tv1", "全");
		map.put("tv2", "17853491140");
		list.add(map);
		
		map = new HashMap<String, Object>();
		map.put("imgview", R.drawable.wf);
		map.put("tv1", "王");
		map.put("tv2", "13053438923");
		list.add(map);
		
		map = new HashMap<String, Object>();
		map.put("imgview", R.drawable.lk);
		map.put("tv1", "鹿");
		map.put("tv2", "15275710175");
		list.add(map);
		map = new HashMap<String, Object>();
		map.put("imgview", R.drawable.qym);
		map.put("tv1", "全");
		map.put("tv2", "17853491140");
		list.add(map);
		
		map = new HashMap<String, Object>();
		map.put("imgview", R.drawable.wf);
		map.put("tv1", "王");
		map.put("tv2", "13053438923");
		list.add(map);
		
		return list;
	}

	@Override
	public void onCreateContextMenu(ContextMenu menu, View v,
			ContextMenuInfo menuInfo) {
		// TODO Auto-generated method stub
		MenuInflater mf = new MenuInflater(jump.this);
		mf.inflate(R.menu.main, menu);
		menu.setHeaderIcon(R.drawable.message);
		menu.setHeaderTitle("请选择");
	}

	@Override
	public boolean onContextItemSelected(MenuItem item) {
		// TODO Auto-generated method stub
		int id = item.getItemId();
		switch (id) {
		case R.id.item1:
			Intent intent = new Intent();
			intent.setAction(intent.ACTION_CALL);
			intent.setData(Uri.parse("tel:" + dh1));
			startActivity(intent);
			break;
		case R.id.item2:
			Intent intent1 = new Intent();
			intent1.setAction(intent1.ACTION_SENDTO);
			intent1.setData(Uri.parse("smsto:" + dh1));
			intent1.putExtra("sms_body", "");
			startActivity(intent1);
			break;
		}
		return super.onContextItemSelected(item);
	}
}

以上就是全部代码，小白初入编程大军！
