[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 p_w_picpath = (ImageView)l1.getChildAt(0);
- p_w_picpath.setImageResource(R.drawable.message);
- return item;
- }
- }
- }
