2.带有返回的Activity消息传递:
MainActivity中核心代码如下:
Button.setOnClickListener(listener);
View.OnClickListener listener=new OnClickListener(){
Public void onClick(View v){
String msg=EditText.getText().toString().trim();
Intent intent=new Intent();
intent.setClass(MainActivity.this,OtherActivity.class);
Bundle bundle=new Bundle();
bundle.putString(“msg”,msg);
intent.putExtras(bundle);
startActivityForResult(intent , requestCode);
}
}
Public void onActivityResult(int requestCode,int resultCode, Intent data){
switch(条件:判断请求Code与响应Code){
case 判别选项:
Bundle bundle=data.getExtras();
String msg=bundle.getString(“msg”);
处理得到的msg;
}
}
OtherActivity中的核心代码:
Bundle bundle=this.getIntent().getExtras();
String msg=bundle.getString(“msg”);
处理msg;
button.setOnClickListener(new View.OnClickListener(
public void onClick(View v){
OtherActivity.this.setResult(resultCode ,OtherActivity.this.getIntent());
}
));
3.发送广播Broadcast
MainActivity中的核心代码如下:
protected void onCreate(Bundle savedInstanceState){
启动服务: Intent intent=new Intent(MainActivity.this,MyService.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startService(intent);
停止服务: Intent intent=new Intent(MainActivity.this,MyService.class);
boolean isYes = stopService(intent);
}
public void onResume(){
super.onResume();
注册广播:IntentFilter intentFilter=new IntentFilter(MyService.FLAG);
MyBroadcastReceiver mReceiver=new MyBroadcastReceiver();
registerReceiver(mReceiver,intentFilter);
}
public void onPause(){
super.onPause();
取消广播:MyBroadcastReceiver mReceiver=new MyBroadcastReceiver();
unregisterReceiver(mReceiver);
}
MyService中的核心代码：
public int onStartCommand(Intent intent,int flags,int startId){
新建个线程，用来处理服务;
创建意图：Intent intent=new Intent(FLAG);
intent.putExtra("msg",MSG);
发送广播: sendBroadcast(i);
}
public void onDestroy(){
flag=false;
super.onDestroy();
}
MyBroadcastReceiver中的核心代码:
public void onReceive(Context context,Intent intent){
Bundle bundle=intent.getExtras();
String msg=bundle.getString("msg");
处理msg;
}
4.利用广播查看手机电量
MainActivity中的核心代码:
int level;//当前电量值

switch(msg.what){
处理消息;
}
}
}
BroadcastReceiver br=new BroadcastReceiver(){
public void onReceive(Context context,Intent intent){
String s=intent.getAction();
if(Intent.ACTION_BATTERY_CHANGED.equals(s)){
level=intent.getIntExtra("level",0);
scale=intent.getIntExtra("scale",100);
hd.sendEmptyMessage(0);
}
}
};
public void onCreate(Bundle savedInstanceState){
注册广播:MainActivity.this.registerReceiver(br,new IntentFilter(Intent.ACTIVITY_BATTERY_CHANGED));
}
5.使用上下文菜单
public void onCreate(Bundle savedInstanceState){
为相应的组件注册上下文菜单:
this.registerForContextMenu(findViewById(R.id.EditText01));
}
public void onCreateContextMenu(ContextMenu menu,View v,ContextMenuInfo menuInfo){
menu.add(组号,菜单号,顺序号,R.string.title);
}
public boolean onContextItemSelected(MenuItem mi){
switch(mi.getItemId()){
case MENU1:
case MENU2:

break;
}
}
6.添加链接事件
Linkify.addLinks(TextView,Linkify.WEB_URLS|Linkfy.EMAIL_ADDRESSED|Linkify.PHONE_NUMBERS);
7.发送Email

static final String[] PEOPLE_PROJECTION={
Contacts.People._ID,//联系人的id
Contacts.People.PRIMARY_PHONE_ID,//电话id
Contacts.People.TYPE,
Contacts.People.NUMBER,//号码
Contacts.People.LABEL,//标签
Contacts.People.NAME
};
protected void onCreate(Bundle savedInstanceState){
获取内容解析：ContentResolver content=getContentResolver();
cursor=content.query(Contacts.People.CONTENT_URI,PEOPLE_PROJECTION,
null,null,Contacts.People.DEFAULT_SORT_ORDER);
myCa=new ContactsAdapter(this,cursor);
autoCompleteTextView.setAdapter(myCa);
autoCompleteTextView.setOnItemClickListener(
new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view, int position, long id){
Cursor c=myCa.getCursor();
c.moveToPosition(position);
获得联系人的电话: String number=c.getString(c.getColumnIndexOrThrow(Contacts.People.Number));
});
}
ContactsAdapter中的核心代码：
ContentResolver myCr;
public ContentResolver(Context context,Cursor c){
myCr=context.getContentResolver();
}
public View newView(Context context, Cursor cursor, ViewGroup parent) {
final LayoutInflater myLi=LayoutInflater.from(context);
final TextView tv=(TextView)myLi.inflate(android.R.layout.simple_dropdown_item_1line, parent,false);
tv.setText(cursor.getColumnIndexOrThrow(Contacts.People.NAME));
return tv;
}
public void bindView(View view, Context context, Cursor cursor) {
((TextView)view).setText(cursor.getString(cursor.getColumnIndexOrThrow(Contacts.People.NAME)));
}
public CharSequence convertToString(Cursor cursor) {
String str=cursor.getString(cursor.getColumnIndexOrThrow(Contacts.People.NAME));
return str;
}
public Cursor runQueryOnBackgroundThread(CharSequence constraint) {
if(getFilterQueryProvider()!=null)
return getFilterQueryProvider().runQuery(constraint);
StringBuilder sb=new StringBuilder();
String[] str=null;
if(constraint!=null){
sb.append("UPPER(");
sb.append(Contacts.People.NAME);
sb.append(") GLOB ?");
str=new String[]{constraint.toString().toUpperCase()+"*"};
}
return myCr.query(Contacts.People.CONTENT_URI, MainActivity.PEOPLE_PROJECTION,sb==null?null:sb.toString(), str, Contacts.People.DEFAULT_SORT_ORDER);
}

PendingIntent pi=PendingIntent.getBroadcaset(context,0,new Intent(),0);
smsManager.sendTextMessage(incomingNumber,null,msg,pi,null);
}
}
}
protected void onCreate(Bundle savedInstance){
监听电话状态:myPhoneStateListener mPSL=new myPhoneStateListener();
TelephonyManager tm=(TelephonyManager)this.getSystemService(Context.TELEPHONY_SERVICE);
tm.listen(mPSL,PhoneStateListener.LISTEN_CALL_STATE);
}
内部类：public class myPhoneStateListener extends PhoneStateListener{
public void onCallStateChanged(int state,String incomingNumber){
switch(state){
case TelephonyManager.CALL_STATE_IDLE:
Bundle bundle=new Bundle();
bundle.putString("number",incomingNumber);
