This utility class can bind a edit menu for ListView, GridView, or other View easily. **Welcome star, fork** ## Screenshots ![ScreenShot](https://github.com/shangmingchao/PopupList/blob/master/screenshots/screenshot_1.png)![ScreenShot](https://github.com/shangmingchao/PopupList/blob/master/screenshots/screenshot_2.png)
![ScreenShot](https://github.com/shangmingchao/PopupList/blob/master/screenshots/screenshot_3.png)![ScreenShot](https://github.com/shangmingchao/PopupList/blob/master/screenshots/screenshot_4.png) ## How do I use PopupList? Just need a `.java` file and a little code. ```java PopupList popupList = new PopupList(context); popupList.bind(anchorView, popupMenuItemList, PopupListListener); ``` ## Sample ```java PopupList popupList = new PopupList(this); popupList.bind(lv_main, popupMenuItemList, new PopupList.PopupListListener() { @Override public boolean showPopupList(View adapterView, View contextView, int contextPosition) { return true; } @Override public void onPopupListClick(View contextView, int contextPosition, int position) { Toast.makeText(MainActivity.this, contextPosition + "," + position, Toast.LENGTH_SHORT).show(); } }); ``` ## Customization You can get more information from the [Wiki](https://github.com/shangmingchao/PopupList/wiki/Configuration) page. ================================================ FILE: build.gradle ================================================ // Top-level build file where you can add configuration options common to all sub-projects/modules. buildscript { repositories { google() jcenter() } dependencies { classpath 'com.android.tools.build:gradle:3.1.3' // NOTE: Do not place your application dependencies here; they belong // in the individual module build.gradle files } } allprojects { repositories { google() jcenter() } } task clean(type: Delete) { delete rootProject.buildDir } ================================================ FILE: gradle/wrapper/gradle-wrapper.properties ================================================ #Mon Mar 13 11:51:38 CST 2017 distributionBase=GRADLE_USER_HOME distributionPath=wrapper/dists zipStoreBase=GRADLE_USER_HOME zipStorePath=wrapper/dists distributionUrl=https\://services.gradle.org/distributions/gradle-4.4-all.zip ================================================ FILE: gradle.properties ================================================ # Project-wide Gradle settings. # IDE (e.g. Android Studio) users: # Gradle settings configured through the IDE *will override* # any settings specified in this file. # For more details on how to configure your build environment visit # http://www.gradle.org/docs/current/userguide/build_environment.html # Specifies the JVM arguments used for the daemon process. # The setting is particularly useful for tweaking memory settings. # Default value: -Xmx10248m -XX:MaxPermSize=256m # org.gradle.jvmargs=-Xmx2048m -XX:MaxPermSize=512m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8 # When configured, Gradle will run in incubating parallel mode. # This option should only be used with decoupled projects.
