消息推送之Jpush极光推送使用心得

//声明一个消息接收器
private MessageReceiver mMessageReceiver;
public static final String MESSAGE_RECEIVED_ACTION = "com.example.push.MESSAGE_RECEIVED_ACTION";
public static final String KEY_TITLE = "title";
public static final String KEY_MESSAGE = "message";
public static final String KEY_EXTRAS = "extras";
//注册消息接收器
public void registerMessageReceiver() {
mMessageReceiver = new MessageReceiver();
IntentFilter filter = new IntentFilter();
filter.setPriority(IntentFilter.SYSTEM_HIGH_PRIORITY);
filter.addAction(MESSAGE_RECEIVED_ACTION);
registerReceiver(mMessageReceiver, filter);
}

//onReceive是指推送到客户端执行下面的语句，这就非常方便的理解推送的意义了。
public class MessageReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
if (MESSAGE_RECEIVED_ACTION.equals(intent.getAction())) {
String messge = intent.getStringExtra(KEY_MESSAGE);
String extras = intent.getStringExtra(KEY_EXTRAS);
StringBuilder showMsg = new StringBuilder();
showMsg.append(messge + "\n");
if (!ExampleUtil.isEmpty(extras)) {
showMsg.append(KEY_EXTRAS + " : " + extras + "\n");
}
setCostomMsg(showMsg.toString());
}
}
}

private void setCostomMsg(String msg){
if (null != msgText) {
msgText.setText(msg);
msgText.setVisibility(android.view.View.VISIBLE);
}
}
