1.默认广播
MainActivity
package com.example.broadcastreceivertest;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void sendNormalClick(View v) {
Intent intent = new Intent(
"com.example.broadcastreceivertest.MY_ACTION");
intent.putExtra("info", "我是一条普通广播");
this.sendBroadcast(intent);
}
}
MyBroadcastReceiver
package com.example.broadcastreceivertest;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.widget.Toast;
public class MyBroadcastReceiver extends BroadcastReceiver {
// public MyBroadcastReceiver(){}//构造方法，可以不写
@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
String info = intent.getStringExtra("info");
Toast.makeText(context, info, Toast.LENGTH_SHORT).show();
}
}
AndroidMainfest.xml
<receiver android:name=".MyBroadcastReceiver">
<intent-filter>
<action android:name="com.example.broadcastreceivertest.MY_ACTION"/>
</intent-filter>
</receiver>
在onResume()注册广播，在onPause()解除注册广播，注册方法：在onResume外创建一个接收器的实例receiver，然后在onResume创建一个IntentFilter的实例filter，调用filter的addAction方法，再调用registerReceiver方法，传入receiver和filter
解除注册调用unregisterReceiver方法，传入receiver参数
3.有序广播
MainActivity
package com.example.orderbroadcastreceivertest;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void sendOrderClick(View v){
Intent intent = new Intent("com.example.orderbroadcastreceivertest.MY_BROADCAST");
this.sendOrderedBroadcast(intent, null);
}
}
MyReceiver1
package com.example.orderbroadcastreceivertest;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.widget.Toast;
public class MyReceiver1 extends BroadcastReceiver{
@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
Bundle data = getResultExtras(false);
String info = data.getString("info");
Toast.makeText(context, "有序广播--1"+info, Toast.LENGTH_SHORT).show();
}
}
MyReceiver2
package com.example.orderbroadcastreceivertest;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.widget.Toast;
public class MyReceiver2 extends BroadcastReceiver{
@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
Toast.makeText(context, "有序广播--2", Toast.LENGTH_SHORT).show();
Bundle data = new Bundle();
data.putString("info", "广播传值");
this.setResultExtras(data);
this.abortBroadcast();
}
}
AndroidMainfest.xml
<receiver android:name=".MyReceiver1">
<intent-filter android:priority="100">
<action android:name="com.example.orderbroadcastreceivertest.MY_BROADCAST"></action>
</intent-filter>
</receiver>
<receiver android:name=".MyReceiver2">
<intent-filter android:priority="200">
<action android:name="com.example.orderbroadcastreceivertest.MY_BROADCAST"></action>
</intent-filter>
</receiver>
4.粘性广播
5.接收开机启动广播和网络状态变化广播
注：<action android:name="android.net.conn.CONNECTIVITY_CHAGE"/>不是系统提供的，要手动添加
6.接收电量变化广播
7.发送短信
MainActivity
package com.example.smstest;
import java.util.ArrayList;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void sendClick(View v) {
// 获取短信管理器
android.telephony.SmsManager manager = android.telephony.SmsManager
.getDefault();
String sms = "我是一条短信";
// 拆分长短信
ArrayList<String> text = manager.divideMessage(sms);
for (int i = 0; i < text.size(); i++) {
manager.sendTextMessage("131****2160", null, text.get(i), null,
null);
}
}
}
<uses-permission android:name="android.permission.SEND_SMS"></uses-permission>
8.接收短信
9.AlarmManager服务
MainActivity
package com.example.alarmtest;
import android.app.Activity;
import android.app.AlarmManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void startClick(View v) {
AlarmManager am = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
long triggerTime = System.currentTimeMillis() + 3000;
Intent intent = new Intent(this, MyReceiver.class);
PendingIntent pi = PendingIntent.getBroadcast(this, 0, intent,
PendingIntent.FLAG_UPDATE_CURRENT);
am.set(AlarmManager.RTC, triggerTime, pi);
// am.setRepeating(AlarmManager.RTC, triggerTime, 8000, pi);
}
}
package com.example.alarmtest;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.widget.Toast;
public class MyReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
Toast.makeText(context, "起床啦！", Toast.LENGTH_LONG).show();
}
}
<receiver android:name=".MyReceiver"></receiver>
