Question

当我点击main.xml上的按钮

时，我试图重新接收BroadcastReceiver

                       **mainfest.xml**
<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name=".MainActivity"
        android:label="@string/title_activity_main" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <receiver android:name=".boardCast">

        <intent-filter>
            <action android:name="borad.cast"/>
              <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </receiver>

</application>

上面的清单文件接收器注册我们自己的动作，如android.action =“broad.cast”

                             **mainActivty.java**
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Button samll = (Button)findViewById(R.id.button1);
    samll.setOnClickListener(new OnClickListener() {

        public void onClick(View v) {
            // TODO Auto-generated method stub
            Intent ii = new Intent(getApplicationContext(),boardCast.class);
            PendingIntent pp = PendingIntent.getBroadcast(getApplicationContext(), 0, ii, 0);

        }
    });
}

上面的Activty类cantain按钮，当我点击那个按钮时，BroadcastReceiver应该触发 boardcast.java

     @Override
public void onReceive(Context context, Intent intent) {
    // TODO Auto-generated method stub
    if(intent.getAction().equals("borad.cast")){
    Toast.makeText(context, "sample", Toast.LENGTH_LONG).show();
    }
}

摆脱未决意图并以这种方式执行：

点击事件调用的onclick：

 public void onClick(View v) {
            // TODO Auto-generated method stub
           broadcastMsg("borad.cast");

        }
    });

//这里是函数定义：

public void broadcastMsg(String intentName) {
        final Intent intent = new Intent(intentName);
        sendBroadcast(intent);
    }

单击Button时触发BroadcastReceiver
