Question

我使用名为“com.lpj.test”的自定义动作静态定义broadcastreceiver。正如在AndroidManifest.xml中注册的那样：

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

coustome BroadcastReceiver Class是这样的：

public class TestBroadcast extends BroadcastReceiver {
public static final String RECEIVER = "com.lpj.test";
@Override
public void onReceive(Context context, Intent intent) {
    if(intent.getAction().equals(RECEIVER)){
        Log.i("BroadcastTest", "Broadcast Start!");
        Toast.makeText(context, "Broadcast Start!",
            Toast.LENGTH_LONG).show();
    }
}

}

然后在主要活动中向我的BroadcastReceiver发送意图

public class replyer extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_replyer);
    this.findViewById(R.id.button).setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            sendBroadcast(new Intent("com.lpj.test"));
        }
    });
}

}

当我点击按钮时它根本不起作用.Logcat没有提供TAG“BroadcastTest”的消息，也没有Toast-Box弹出。没有发生。

我认为操作名称中的问题是。（点），请尝试以下方式，

<receiver android:name=".TestBroadcast">
            <intent-filter>
            <action android:name="comLpjTest"/>
</intent-filter>


@Override
public void onClick(View v) 
{
    sendBroadcast(new Intent("comLpjTest"));
}

自定义静态BroadcastReceiver无法正常工作
