我是 android 新手，我正在尝试广播演示，我尽我最大的努力阅读了文档，但它不起作用。请看一下我的代码：
BroadcastDemoActivity.java
package com.broadcastdemo;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
public class BroadcastDemoActivity extends Activity {
/** Called when the activity is first created. */
public static final String PUBLIC_HOLIDAYS = "com.paad.action.PUBLIC_HOLIDAYS";
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Intent intent = new Intent(PUBLIC_HOLIDAYS);
intent.putExtra("Holiday", "8th April is a holiday");
sendBroadcast(getIntent());
}
}
接收.java
package com.broadcastdemo;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.widget.Toast;
public class Receive extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
String message = intent.getStringExtra("Holiday");
Toast.makeText(context, message, Toast.LENGTH_SHORT).show();
}
}
清单.xml

我知道我遗漏了一些我不知道的东西，请帮忙。
