1、sendBroadcast方法发送广播。
package com.example.android_broadcast_normal;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class MainActivity extends Activity {
private Button btn;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btn=(Button)this.findViewById(R.id.button1);
//发送广播
btn.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Intent intent=new Intent(MainActivity.this,MyReceiver.class);
sendBroadcast(intent);
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}

package com.example.android_broadcast_normal;

/**

@SuppressLint("NewApi")
public class MyReceiver extends BroadcastReceiver {
//通知管理实例
private NotificationManager notificationManager;
//创建通知者实例
private Notification.Builder builder;
@TargetApi(Build.VERSION_CODES.HONEYCOMB)
@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub

notificationManager=(NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);

builder.setContentText("你好");
builder.setSmallIcon(R.drawable.ic_launcher);

notificationManager.notify(10086,builder.build());
}
}
2、发送顺序广播
package com.example.android_brocast_order;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class MainActivity extends Activity {
private Button btn1,btn2;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btn1=(Button)this.findViewById(R.id.button1);
btn2=(Button)this.findViewById(R.id.button2);
btn1.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// 多个广播接收者发送广播
Intent intent=new Intent();
intent.putExtra("name", "李华");
intent.setAction("com.yqq.mutilBrocast");
sendBroadcast(intent);
}
});
//发送有序广播
btn2.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
//创建意图
Intent intent=new Intent();
intent.putExtra("name","android");
intent.setAction("com.yqq.mutilBrocast");
//发送有序广播
sendOrderedBroadcast(intent, null);
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
