1.创建布局文件activity_broadcast.xml

2.创建Activity

public class BroadcastActivity extends Activity {    //设定为com.china.ui.NEW_LIFEFORM，显示内容前，多一条信息"收到广播信息"；    //public static final String MY_NEW_LIFEFORM="com.china.ui.NEW_LIFEFORM";    public static final String MY_NEW_LIFEFORM="NEW_LIFEFORM";    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_broadcast);        //传递数据        final Intent intent=new Intent(MY_NEW_LIFEFORM);        intent.putExtra("msgContent", "测试内容");        //初始化按钮        Button button=(Button) findViewById(R.id.sendBroadcastIntent);        button.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View arg0) {                sendBroadcast(intent);            }        });    }}

3.创建BroadcastReceiver

public class Receiver extends BroadcastReceiver {    @Override    public void onReceive(Context context, Intent intent) {        String content=intent.getStringExtra("msgContent");        CharSequence string="收到信息:"+content;        Toast.makeText(context, string, Toast.LENGTH_LONG).show();    }}

4.配置AndroidManifest.xml
