Android Popupwindow implement right, left, and bottom pop-up menus _android

This tutorial for you to share the Android Popupwindow pop-up menu specific code, for your reference, the specific content as follows

Project code: Http://xiazai.jb51.net/201611/yuanma/PopupLeftMenu (jb51.net). rar

The Project SDK is 5.1, and it is recommended that you copy the code to your own project.

The code is as follows:

Mainactivity class:

Two layout files:

1.activity_main.xml, just three button.

<linearlayout xmlns:android= "http://schemas.android.com/apk/res/android" 
 xmlns:tools= "http:// Schemas.android.com/tools " 
 android:layout_width=" fill_parent " 
 android:layout_height=" Fill_parent 
 " android:orientation= "vertical" > 
 
 <button 
  android:id= "@+id/pop_left_btn" 
  android:layout_width= "Fill_parent" 
  android:layout_height= "wrap_content" 
  android:text= "@string/pop_left"/> 
  
 < Button 
  android:id= "@+id/pop_right_btn" 
  android:layout_width= "fill_parent" 
  android:layout_height = "Wrap_content" 
  android:text= "@string/pop_right"/> 
  
 <button android:id= 
  "@+id/pop_bottom_ BTN " 
  android:layout_width=" fill_parent " 
  android:layout_height=" wrap_content " 
  android:text=" @ String/pop_bottom "/> 
  
 
</LinearLayout>

2. Pop.xml, also three button, you can modify your own

 <?xml version= "1.0" encoding= "Utf-8"?> "<linearlayout xmlns:android=" http:// 
 Schemas.android.com/apk/res/android "android:layout_width=" fill_parent "android:layout_height=" Fill_parent " android:orientation= "Vertical" > <!--<linearlayout android:layout_width= "Wrap_content" android:layout _height= "fill_parent" android:orientation= "vertical" android:background= "#ffffff" >--> <button Andro Id:id= "@+id/open" android:layout_width= "fill_parent" android:layout_height= "wrap_content" android:text= "@strin G/open "/> <button android:id=" @+id/save "android:layout_width=" fill_parent "android:layout_height=" WR Ap_content "android:text=" @string/save "/> <button android:id=" @+id/close "android:layout_width=" Fill_  Parent "android:layout_height=" wrap_content "android:text=" @string/close "/> <!--</LinearLayout> --> </LinearLayout> 

Strings.xml

<string name= "Pop_left" > Pop-up left menu </string> 
 <string name= "Pop_right" > Popup Right Menu </string> 
 <string name= "Pop_bottom" > Pop-up bottom menu </string> 
 <string name= "open" > Open </string> 
 <string name= "Save" > Save </string> 
 <string name= "Close" > Off </string> 

Styles.xml

<style name= "Animationleftfade" > 
  <item name= "android:windowenteranimation" > @anim/in_lefttoright </item> 
  <item name= "android:windowexitanimation" > @anim/out_righttoleft</item> 
 </ style> 
  
 <style name= "Animationrightfade" > 
  <item name= "Android:windowenteranimation" > @anim in_righttoleft</item> 
  <item name= "android:windowexitanimation" > @anim/out_lefttoright</item > 
 </style> 
  
 <style name= "Animationbottomfade" > 
  <item name= "Android: Windowenteranimation "> @anim/in_bottomtotop</item> 
  <item name=" Android:windowexitanimation "> @anim/out_toptobottom</item> 
 </style> 

Left pop-up menu animation file:

In_lefttoright.xml: From left into

<?xml version= "1.0" encoding= "Utf-8"?> <set xmlns:android= 
"http://schemas.android.com/apk/res/" Android "> 
  
 <translate 
  android:fromxdelta=" -100% " 
  android:toxdelta=" 0 " 
  android:duration=" "/> 
  
</set> 

Out_righttoleft.xml: From the right

<?xml version= "1.0" encoding= "Utf-8"?> <set xmlns:android= 
"http://schemas.android.com/apk/res/" Android "> 
  
 <translate android:fromxdelta=" 0 " 
  android:toxdelta=" -100% " 
  android:duration=" 500 "/> 
 
</set> 

Other animated files are written for their own reference, which is used by Fromxdelta, Fromydelta, Toxdelta and Toydelta.
