android通过toast实现悬浮通知效果,如图:
实现的功能:
- 自定义悬浮弹窗;
- 点击其他地方该布局不受影响;
- 可自定义显示时间;
- 可以设置点击事件;
代码如下:

xml布局:
<?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/ll_push_content" android:layout_width="match_parent" android:layout_height="wrap_content" android:background="@drawable/bg_push_message" android:orientation="vertical"> <textview android:id="@+id/tv_title" android:layout_width="match_parent" android:layout_height="wrap_content" android:textcolor="@color/black" android:text="标题" android:maxlines="2" android:ellipsize="end" android:textstyle="bold" android:textsize="@dimen/text_size_14" /> <textview android:id="@+id/tv_content" android:layout_width="match_parent" android:layout_height="wrap_content" android:textcolor="@color/black_808080" android:textsize="@dimen/text_size_13" android:maxlines="3" android:ellipsize="end" android:layout_margintop="@dimen/margin_large" android:text="1"/> </linearlayout>

使用方法:
activity中需要初始化一次:
pushtoast.getinstance().init(this);
调用:
pushtoast.getinstance().createtoast(msg.title,msg.text,umengpushentity.getextramap());
