SMS管理:收信箱 发信息 编写新信息

SMS管理

 

 

[功能]

 

1. 收信箱：显示所有收到的信息 且实时显示 即：当有新信息收到 能自动刷新显示

 

2. 发信箱：显示所有已发信息 同上

 

3. 编写新信息： 鉴于一些问题 打算不自行定义 而只通过Intent调用系统的

 

 

 

[原理]

 

1. 通过目标Uri显示收信箱 发信箱  目标Uri：content://sms/inbox content://sms/sent

 

2. 实时刷新：一个办法是开辟thread 定时查询目标Uri 显示之  但会带来一些效能影响 所以决定使用ContentObserve监听目标Uri 当有变动 由ContentObserve通知注册方 该Uri:content://sms

 

3. 注意：ContentObserve不能监听: content://sms/inbox & content://sms/sent 而只能监听content://sms

 

 

[代码 步骤]

 

1. 定义SMSObserver 用于监听目标 并通过Handle通知注册方

 

public class SMSObserver extends ContentObserver {
	public final static int SMS_CHANGE = 0;
	
	Handler handle;
	public SMSObserver(Handler h) {
		super(h);
		// TODO Auto-generated constructor stub
		handle = h;
	}
	
	public void onChange(boolean selfChange) {   
        // TODO Auto-generated method stub   
        super.onChange(selfChange);   
        
        //notify SMSInbox & SMSSent
        handle.sendEmptyMessage(SMS_CHANGE);
    }

}

 

 

 

2. 定义注册方：SMSInbox 鉴于SMSSent与其原理类似 故打算以SMSInbox为例 

 

 

> 2.1. 显示当前所有收信箱 并与ListView适配

 

 

lv = (ListView)findViewById(R.id.list);
        
        cursor = getContentResolver().query(Uri.parse("content://sms/inbox"), null, null, null, null); 
        
        adapter = new ItemAdapter(this);
        lv.setAdapter(adapter);

 

 

> 2.2. 定义Handle 用于接受变动 并注册与ContentObserve 当接到通知后 查询目标Uri 并刷新显示

 

 

handler = new Handler(){
        	public void handleMessage(Message msg){
        		if(msg.what == SMSObserver.SMS_CHANGE){
        			cursor = getContentResolver().query(Uri.parse("content://sms/inbox"), null, null, null, null); 
        			adapter.notifyDataSetChanged();
        		}
        	
        	}
        };
        sObserver = new SMSObserver(handler);
        this.getContentResolver().registerContentObserver(Uri.parse("content://sms"), true, sObserver);
        

 

 

> 2.3.  SMSInbox 仅用于显示 收信箱  故定义 SMSDetails extends Activity 用于详细显示 sms信息  

 

- 2.3.1. 定义布局：details.xml

 

 

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
<TextView  
	android:id="@+id/detailsNumber"
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    />
<TextView  
	android:id="@+id/detailsBody"
    android:layout_width="fill_parent" 
    android:layout_height="200dip" 
    />
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal"
    android:layout_width="300dip"
    android:layout_height="wrap_content"
    >
<Button  
	android:id="@+id/detailsReply"
    android:layout_width="100dip" 
    android:layout_height="wrap_content" 
    android:layout_gravity="left"
    android:text="回复"
    />
<Button  
	android:id="@+id/detailsOK"
    android:layout_width="100dip" 
    android:layout_height="wrap_content" 
    android:layout_gravity="right"
    android:text="确定"
    />
</LinearLayout>
</LinearLayout>

 

 

 

- 2.3.2. 其中2个TextView 分别显示信息地址和正文 2个Button 一个用于关闭当前窗口 一个用于短信回复 且自动填充 收信人地址

 

public class SMSDetails extends Activity {

	TextView textNumber,textBody;
	Button btnOK,btnReply;
	
	OnClickListener cl;
	
	String address,body;
	/** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.details);
        
        textNumber = (TextView)findViewById(R.id.detailsNumber);
        textBody = (TextView)findViewById(R.id.detailsBody);
        
        btnReply = (Button)findViewById(R.id.detailsReply);
        btnOK = (Button)findViewById(R.id.detailsOK);
        
        Intent i = this.getIntent();
        Bundle bundle = i.getExtras();
        
        address = bundle.getString("address");
        body = bundle.getString("body");
        
        textNumber.setText("from:"+address);
        textBody.setText("message body:\n"+body); 

        cl = new OnClickListener(){

			@Override
			public void onClick(View arg0) {
				// TODO Auto-generated method stub
				switch(arg0.getId()){
				case R.id.detailsReply:
					sendGoNativeNew(address);
					break;
					
				case R.id.detailsOK:
					sendBack();
					break;
				}
			}
        	
        };
        
        btnReply.setOnClickListener(cl);
        btnOK.setOnClickListener(cl);
    }
    
    public void sendGoNativeNew(String address){
    	//native send sms app
        Intent sendIntent = new Intent(Intent.ACTION_SENDTO, Uri.parse("sms://"));
        //auto fill "address"
        sendIntent.putExtra("address", address);
        
        startActivity(sendIntent);
    }
    
    public void sendBack(){
    	Intent i = new Intent();
    	this.setResult(RESULT_OK, i);
    	this.finish();
    }
}

 

 

 

- 2.3.3.  点击SMSInbox 某项 跳转到SMSDetails

 

lv.setOnItemClickListener(new OnItemClickListener(){
			@Override
			public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
					long arg3) {
				// TODO Auto-generated method stub
				cursor.moveToPosition(arg2);
				String body = cursor.getString(cursor.getColumnIndexOrThrow("body")).toString(); 
				String address = cursor.getString(cursor.getColumnIndexOrThrow("address")).toString();
				
				Bundle b = new Bundle();
				b.putString("body", body);
				b.putString("address", address);
				
				Intent intent = new Intent(SMSInbox.this,SMSDetails.class);
				intent.putExtras(b);
				
				startActivity(intent);
			}
        	
        });

 

 

 

- 2.3.4. 其中 item.xml 用于定义子项布局

 

 

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    >
<ImageView  
	android:id="@+id/body"
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    />
<TextView  
	android:id="@+id/num"
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:paddingLeft="5dip"
    />
</LinearLayout>
<TextView  
	android:id="@+id/body"
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:paddingLeft="10dip"
    />
</LinearLayout>

 

 

 

3. 鉴于SMSSent与SMSInbox大同小异 故不再细说 仅补上代码

 

public class SMSSent extends Activity {
	ListView lv;
	
	Cursor cursor;
	ItemAdapter adapter;
	
	SMSObserver sObserver;
	Handler handler;
	
	/** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.list);
        setTitle(R.string.sent);
        
        lv = (ListView)findViewById(R.id.list);
        
        cursor = getContentResolver().query(Uri.parse("content://sms/sent"), null, null, null, null); 
        
        adapter = new ItemAdapter(this);
        lv.setAdapter(adapter);
        
        lv.setOnItemClickListener(new OnItemClickListener(){
			@Override
			public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
					long arg3) {
				// TODO Auto-generated method stub
				cursor.moveToPosition(arg2);
				String body = cursor.getString(cursor.getColumnIndexOrThrow("body")).toString(); 
				String address = cursor.getString(cursor.getColumnIndexOrThrow("address")).toString();
				
				Bundle b = new Bundle();
				b.putString("body", body);
				b.putString("address", address);
				
				Intent intent = new Intent(SMSSent.this,SMSDetails.class);
				intent.putExtras(b);
				
				startActivity(intent);
			}
        	
        });
        
        //register SMSObserve
        handler = new Handler(){
        	public void handleMessage(Message msg){
        		if(msg.what == SMSObserver.SMS_CHANGE){
        			cursor = getContentResolver().query(Uri.parse("content://sms/sent"), null, null, null, null); 
        			adapter.notifyDataSetChanged();
        		}
        	
        	}
        };
        sObserver = new SMSObserver(handler);
        this.getContentResolver().registerContentObserver(Uri.parse("content://sms"), true, sObserver);
        
    }
    
    
    public class ItemAdapter extends BaseAdapter {
    	Activity activity;
    	
    	public ItemAdapter(Activity a){
    		activity = a;
    	}
    	
		@Override
		public int getCount() {
			// TODO Auto-generated method stub
			return cursor.getCount();
		}

		@Override
		public Object getItem(int arg0) {
			// TODO Auto-generated method stub
			return cursor.getString(arg0);
		}

		@Override
		public long getItemId(int arg0) {
			// TODO Auto-generated method stub
			return arg0;
		}

		@Override
		public View getView(int arg0, View arg1, ViewGroup arg2) {
			// TODO Auto-generated method stub
			return composeItem(arg0);
		}
		
		private View composeItem(int position){
			cursor.moveToPosition(position);
			String body = cursor.getString(cursor.getColumnIndexOrThrow("body")).toString(); 
			String number = cursor.getString(cursor.getColumnIndexOrThrow("address")).toString();
			
			LinearLayout item = (LinearLayout)activity.getLayoutInflater().inflate(R.layout.item, null);
			
			LinearLayout l1 = (LinearLayout)item.getChildAt(0);
			
			TextView tbody = (TextView)item.getChildAt(1);
			if(tbody != null){
				tbody.setText(body);
			}
			
			TextView tnum = (TextView)l1.getChildAt(1);
			if(tnum != null){
				tnum.setText(number);
			}
			
			ImageView image = (ImageView)l1.getChildAt(0);
			image.setImageResource(R.drawable.message);
			
			return item;
		}
    	
    }
}

 

 

 

4. emulator 运行截图

 

 > 4.1. SMSInbox:

 

- 4.1.1. 通过telnet localhost 5554 登录emulator  通过 sms send 123 hello to 123 模拟发送短信

 

- 4.1.2. 短信发送记录为：

 

Android Console: type 'help' for a list of commands
OK
sms send 12 ds
OK
sms send 23 hi to 23
OK
sms send 34 i am griddinshi
OK

 

- 4.1.3. SMSInbox:

 

 

 

> 4.2. SMSSent

 

- 4.2.1. 已发短信记录：

 

 

- 4.2.2. SMSSent:

 

 

 

 

 

5. 未解决问题：

 

> 5.1. ContentObserver 只能监听content://sms  而不支持content://sms/inbox content://sms/sent  个人猜测是因为：android 在写sms数据库 insert(...) 没有通过ContentResolver通知content://sms/inbox content://sms/sent 所致 即：没有以下代码：

 

getContext().getContentResolver().notifyChange(noteUri, null);

 

 

6. 如果写的有问题的 欢迎讨论  否则 请回帖支持一些

6 楼 llguo130 2012-08-24  

楼主你好
我也是使用contentObserver来监听 content://sms
但是每次收到短信，onchange()方法都会被调用两次，是为什么？楼主遇到过吗？

5 楼 wzbhbb 2011-04-02  

好文章，受益了，不知“ 而不支持content://sms/inbox content://sms/sent  ”这句话是什么意思？

4 楼 zhq56030207 2010-12-08  

当短信的数目发生变化时，如何监听得到／？

3 楼 ableouou 2010-10-27  

要做就基于源码开发吧

2 楼 gryphone 2010-06-07  

lveyo 写道

请问，如果遇到群发信息，程序怎么处理？

群发？抱歉 因为我没有真机做测试 而emulator又不支持
不过那要看我怎么做了吧
