1. AppMsg
优雅的弹出类似Toast的消息提示，支持3种状态Alert（警告），Confirm（确认）以及Info（消息）。
2. AppMsg使用：
（1）AppMsg下载地址：
https://github.com/johnkil/Android-AppMsg
（2）下载成功之后，解压如下：
（3）导入library 和 sample 分别导入Eclipse如下：
（4）首先我们来到主布局文件activity_main.xml，如下：
1 <ScrollView xmlns:android="http://schemas.android.com/apk/res/android" 2 xmlns:tools="http://schemas.android.com/tools" 3 android:layout_width="match_parent" 4 android:layout_height="match_parent" 5 android:fillViewport="true"> 6 7 <LinearLayout 8 android:id="@+id/animated_root" 9 android:layout_width="match_parent" 10 android:layout_height="match_parent" 11 android:gravity="center" 12 android:orientation="vertical" 13 android:animateLayoutChanges="true" 14 android:padding="48dp"> 15 16 <TextView 17 android:layout_width="wrap_content" 18 android:layout_height="wrap_content" 19 android:layout_gravity="left" 20 android:textAllCaps="true" 21 android:text="@string/style" 22 /> 23 <Spinner 24 android:id="@+id/style_spnr" 25 android:layout_width="match_parent" 26 android:layout_height="wrap_content" 27 android:minHeight="48dp" 28 android:spinnerMode="dropdown" 29 android:entries="@array/styles" 30 android:prompt="@string/style" 31 /> 32 <TextView 33 android:layout_width="wrap_content" 34 android:layout_height="wrap_content" 35 android:layout_gravity="left" 36 android:textAllCaps="true" 37 android:text="@string/priority" 38 /> 39 <Spinner 40 android:id="@+id/priority_spnr" 41 android:layout_width="match_parent" 42 android:layout_height="wrap_content" 43 android:minHeight="48dp" 44 android:spinnerMode="dropdown" 45 android:entries="@array/priorities" 46 android:prompt="@string/priority" 47 /> 48 49 <CheckBox 50 android:id="@+id/bottom" 51 android:layout_width="match_parent" 52 android:layout_height="wrap_content" 53 android:text="@string/bottom" /> 54 55 <LinearLayout 56 android:id="@+id/alt_parent" 57 android:visibility="gone" 58 android:layout_width="match_parent" 59 android:layout_height="wrap_content" 60 android:minHeight="48dp" 61 android:orientation="vertical" /> 62 63 <CheckBox 64 android:id="@+id/parent_chk" 65 android:layout_width="match_parent" 66 android:layout_height="wrap_content" 67 android:text="@string/custom_parent" /> 68 69 <EditText 70 android:id="@+id/provided_txt" 71 android:layout_width="match_parent" 72 android:layout_height="wrap_content" 73 android:hint="@string/your_message_here" 74 /> 75 76 <Button 77 android:id="@+id/show" 78 android:layout_width="match_parent" 79 android:layout_height="wrap_content" 80 android:onClick="buttonClick" 81 android:text="@string/show_appmsg" /> 82 83 <Button 84 android:id="@+id/cancel_all" 85 android:layout_width="match_parent" 86 android:layout_height="wrap_content" 87 android:onClick="buttonClick" 88 android:text="@string/cancel_all" /> 89 90 </LinearLayout> 91 </ScrollView>
布局效果如下：
前面提到可以显示Alert、Confirm、Info三种消息样式，其实还可以显示自定义的消息样式，这里我们自定义一个消息样式为sticky.xml，如下：
1 <?xml version="1.0" encoding="utf-8"?> 2 3 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 4 android:layout_width="match_parent" 5 android:layout_height="wrap_content" 6 android:minHeight="48dp"> 7 8 <ImageButton 9 android:id="@+id/remove_btn" 10 android:layout_width="wrap_content" 11 android:layout_height="wrap_content" 12 android:layout_alignParentRight="true" 13 android:layout_centerVertical="true" 14 android:minWidth="48dp" 15 android:minHeight="48dp" 16 android:src="@drawable/ic_action_cancel_inset" 17 style="@style/SelectableItem"/> 18 19 20 <TextView 21 android:id="@android:id/message" 22 android:layout_width="match_parent" 23 android:layout_height="wrap_content" 24 android:layout_toLeftOf="@id/remove_btn" 25 android:layout_centerVertical="true" 26 android:gravity="center" 27 android:padding="8dp" 28 android:textColor="#ff222222" 29 android:textIsSelectable="false" 30 android:textSize="14sp" 31 android:textStyle="bold"/> 32 33 </RelativeLayout>
布局效果图，如下：
（5）在MainActivity工程之中找到主Activity，修改为extends Activity，如下：
