一：注册设置后台静态广播

import android.app.Activity;  import android.content.BroadcastReceiver;  import android.content.Context;  import android.content.Intent;  import android.content.IntentFilter;  import android.os.Bundle;    import android.view.View;  import android.view.View.OnClickListener;  import android.widget.Button;  import android.widget.TextView;    public class MainActivity extends Activity {      private Button mButton;      private TextView mTextView;      public static String ACTION_INTENT_TEST = "com.demo.test";        @Override      protected void onCreate(Bundle savedInstanceState) {          super.onCreate(savedInstanceState);          setContentView(R.layout.activity_main);          mTextView = (TextView) findViewById(R.id.message_tv);          mButton = (Button) findViewById(R.id.send_btn);          mButton.setOnClickListener(new OnClickListener() {                @Override              public void onClick(View v) {                  // TODO Auto-generated method stub                  Intent mIntent = new Intent(ACTION_INTENT_TEST);                  sendBroadcast(mIntent);              }          });          registerMessageReceiver();      }      //在销毁时要与广播解绑      @Override      protected void onDestroy() {          unregisterReceiver(mMessageReceiver);          super.onDestroy();      }        public MessageReceiver mMessageReceiver;      public static String ACTION_INTENT_RECEIVER = "com.demo.receiver";        /**      * 动态注册广播      */      public void registerMessageReceiver() {          mMessageReceiver = new MessageReceiver();          IntentFilter filter = new IntentFilter();            filter.addAction(ACTION_INTENT_RECEIVER);          registerReceiver(mMessageReceiver, filter);      }        public class MessageReceiver extends BroadcastReceiver {            @Override          public void onReceive(Context context, Intent intent) {              // TODO Auto-generated method stub              if (intent.getAction().equals(ACTION_INTENT_RECEIVER)) {                  mTextView.setText(intent.getStringExtra("message"));              }          }        }  }

二：自定义广播接收器

import android.content.BroadcastReceiver;  import android.content.Context;  import android.content.Intent;  import android.os.Bundle;  import android.util.Log;   public class MyBroadCast extends BroadcastReceiver{        public MyBroadCast()      {          Log.v("BROADCAST_TAG", "MyBroadCast");      }      @Override      public void onReceive(Context context, Intent intent) {          // TODO Auto-generated method stub          Log.v("BROADCAST_TAG", "onReceive");          Bundle bundle = intent.getExtras();          if(intent.getAction().equals(MainActivity.ACTION_INTENT_TEST))          {              processCustomMessage(context, bundle);          }      }      //send msg to MainActivity          private void processCustomMessage(Context context, Bundle bundle) {                                Intent mIntent=new Intent(MainActivity.ACTION_INTENT_RECEIVER);                  mIntent.putExtra("message", "测试Broadcast与Activity之间的通信");                  context.sendBroadcast(mIntent);                            }    }

三：配置注册静态广播

<receiver android:name=".MyBroadCast">             <intent-filter >                 <action android:name="com.demo.test"/>             </intent-filter>         </receiver>
