通知栏图片
通知栏的小图标建议使用纯白色，在通知栏显示的时候就是白色，拉下来的时候就会变成灰色的
在图片文件夹中放置不同尺寸的图标
24 × 24 (mdpi)
36 × 36 (hdpi)
48 × 48 (xhdpi)
72 × 72 (xxhdpi)
96 × 96 (xxxhdpi)
封装好的通知工具类
调用弹出通知栏的方法：
public static void showNotification(Context context, String conversationType, String targetId, String avatar, String name, String content) {
NotificationManager notificationManager = (NotificationManager) context.getSystemService(NOTIFICATION_SERVICE);
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context);
mBuilder.setPriority(Notification.PRIORITY_MAX);//可以让通知显示在最上面
mBuilder.setSmallIcon(R.mipmap.small_icon);
mBuilder.setWhen(System.currentTimeMillis());
mBuilder.setAutoCancel(true);
if (shouldRemind(true)) {
mBuilder.setDefaults(Notification.DEFAULT_ALL);//使用默认的声音、振动、闪光
}
Bitmap bmIcon = BitmapFactory.decodeResource(
context.getResources(), R.mipmap.ic_launcher);
Bitmap largeIcon = bmIcon;
Bitmap bmAvatar = GetImageInputStream(avatar);
if (bmAvatar != null) {
//如果可以获取到网络头像则用网络头像
largeIcon = bmAvatar;
}
content = name + ":" + content; //内容为 xxx:内容
// int unreadCount = RongIMClient.getInstance().getUnreadCount(conversationType, targetId);
// if (unreadCount > 1) {
// //如果未读数大于1，则还有拼接上[x条]
// String num = String.format(UIUtils.getString(R.string.notification_num_format), unreadCount);
// content = num + content;//内容为 [x条] xxx:内容
// }
mBuilder.setLargeIcon(largeIcon);
mBuilder.setContentTitle(name);
Intent intent = getIntent(context, conversationType, targetId, name);
PendingIntent pendingIntent = PendingIntent.getActivity(context, getRandomNum(), intent, PendingIntent.FLAG_UPDATE_CURRENT);
//通知首次出现在通知栏，带上升动画效果的
mBuilder.setTicker(content);
//内容
mBuilder.setContentText(content);
mBuilder.setContentIntent(pendingIntent);
Notification notification = mBuilder.build();
int notifyId = 0;
try {
notifyId = Integer.parseInt(targetId);
} catch (NumberFormatException e) {
e.printStackTrace();
notifyId = -1;
}
//弹出通知栏
notificationManager.notify(notifyId, notification);
}
获取网络图片(头像)的方法
/**
* 获取网络图片
*
* @param imageurl 图片网络地址
* @return Bitmap 返回位图
*/
public static Bitmap GetImageInputStream(String imageurl) {
URL url;
HttpURLConnection connection = null;
Bitmap bitmap = null;
try {
url = new URL(imageurl);
connection = (HttpURLConnection) url.openConnection();
connection.setConnectTimeout(6000); //超时设置
connection.setDoInput(true);
connection.setUseCaches(false); //设置不使用缓存
InputStream inputStream = connection.getInputStream();
bitmap = BitmapFactory.decodeStream(inputStream);
inputStream.close();
} catch (Exception e) {
e.printStackTrace();
}
return bitmap;
}
通知栏跳转意图的创建
/**
* 产生对应的intent
*/
private static Intent getIntent(Context context, String conversationType, String targetId, String title) {
Intent intent = new Intent();
intent.setAction("ActionConversation");
intent.setFlags(intent.FLAG_ACTIVITY_NEW_TASK);
Uri.Builder uriBuilder = Uri.parse("wechat://" + context.getPackageName()).buildUpon();
uriBuilder.appendPath("conversation");
uriBuilder.appendQueryParameter(Constant.CONVERSATION_TYPE, conversationType)
.appendQueryParameter(Constant.TARGET_ID, targetId)
.appendQueryParameter(Constant.TITLE, title);
intent.setData(uriBuilder.build());
Log.i("uri: ", uriBuilder.build().toString());
return intent;
}
在Manifest中，配置对应配置点击通知栏跳转的相应activity的uri配置:
<activity
android:name=".MainActivity"
android:configChanges="keyboardHidden|screenSize|orientation"
android:screenOrientation="portrait"
android:launchMode="singleTask"
>
...
<intent-filter>
<action android:name="ActionConversation"/>
<category android:name="android.intent.category.DEFAULT"/>
<data
android:host="com.chaychan.wechatnotification"
android:pathPrefix="/conversation"
android:scheme="wechat"/>
</intent-filter>
</activity>
其中 intent-filter 中配置了activity的匹配规则，action对应getIntent()方法中设置的action的值，data中的scheme和pathPrefit也对应getIntent()方法中设置的uri的路径。
MainActivity中处理传递的Intent
@Override
protected void onNewIntent(Intent intent) {
super.onNewIntent(intent);
Uri uri = intent.getData();
if (!uri.getScheme().equals("wechat")) {
return;
}
if (uri.getPath().contains("/conversation")) {
String conversationType = uri.getQueryParameter(Constant.CONVERSATION_TYPE);
String targetId = uri.getQueryParameter(Constant.TARGET_ID);
String title = uri.getQueryParameter(Constant.TITLE);
Intent conversationIntent = new Intent(this, ConversationActivity.class);
conversationIntent.putExtra(Constant.TITLE,title);
conversationIntent.putExtra(Constant.TARGET_ID,targetId);
conversationIntent.putExtra(Constant.CONVERSATION_TYPE,conversationType);
startActivity(conversationIntent);
}
}
在onNewIntent()处理通知栏传递过来的intent，根据传递过来的uri进行跳转。
