 # PopupWindowCompat
-兼容android 7.x , 8.0 etc的Popwindow
+[![Build Status](https://travis-ci.com/wang0826jj/PopupWindowCompat.svg?branch=master)](https://travis-ci.com/wang0826jj/PopupWindowCompat) [![Bintray](https://api.bintray.com/packages/wang0826jj/maven/PopupWindowCompat/images/download.svg)](https://bintray.com/wang0826jj/maven/PopupWindowCompat/_latestVersion) [![GitHub license](https://img.shields.io/github/license/wang0826jj/PopupWindowCompat.svg)](https://github.com/wang0826jj/PopupWindowCompat/blob/master/LICENSE)
 
-### 问题描述
-前段时间发现Popupwindow在8.0的手机上显示成全屏了，搜了下发现7.0以上就有这个问题了，好久没写Popwindow了，才知道（尴尬）。于是总结了在以下情况可能出问题：
+## [English](README_EN.md) | 中文
 
-1. 当设置PopupWindow 的高度为 MATCH_PARENT，调用 showAsDropDown(View anchor) 时，在 7.0 之前，会在 anchor 下边缘到屏幕底部之间显示 PopupWindow；而在 7.0系统上（包括7.1, 8.0）的 PopupWindow 会占据整个屏幕（除状态栏之外）。
-2. 当设置PopupWindow 的高度为 WRAP_CONTENT，调用 showAsDropDown(View anchor) 时，没有兼容性问题。
-3. 当设置PopupWindow 的高度为自定义的值height，调用 showAsDropDown(View anchor)时， 如果 height > anchor 下边缘与屏幕底部的距离， 则还是会出现7.0以上显示异常的问题；否则，不会出现该问题。
+一个兼容android 7.x , 8.x etc系统的Popwindow，主要适配当设置高度为match_parent时，调用`popupWindow.showAsDropDown()`后的高度全屏问题，同时适配了是否有虚拟按键，虚拟按键是否显示的情况。
 
-### 问题解决
-好了，现在我们知道问题出现的情况了，上网搜了很多解决方案，发现都不能完美解决问题，如以下代码：
+## 添加到项目
 
-```java
-if (Build.VERSION.SDK_INT >= 24) {
-     int[] location = new int[2];
-     anchor.getLocationOnScreen(location);
-     // 7.1 版本处理
-     if (Build.VERSION.SDK_INT == 25) {
-         WindowManager windowManager = (WindowManager) pw.getContentView().getContext().getSystemService(Context.WINDOW_SERVICE);
-         if (windowManager != null) {
-             int screenHeight = windowManager.getDefaultDisplay().getHeight();
-             // PopupWindow height for match_parent, will occupy the entire screen, it needs to do special treatment in Android 7.1
-             pw.setHeight(screenHeight - location[1] - anchor.getHeight() - yoff);
-         }
-     }
-     pw.showAtLocation(anchor, Gravity.NO_GRAVITY, xoff, location[1] + anchor.getHeight() + yoff);
-
- } else {
-     pw.showAsDropDown(anchor, xoff, yoff);
- }
-```
-或者这种代码：
-
-```java
-public static void showAsDropDown(final PopupWindow pw, final View anchor, final int xoff, final int yoff) {
-    if (Build.VERSION.SDK_INT >= 24) {
-        Rect visibleFrame = new Rect();
-        anchor.getGlobalVisibleRect(visibleFrame);
-        int height = anchor.getResources().getDisplayMetrics().heightPixels - visibleFrame.bottom;
-        pw.setHeight(height);
-        pw.showAsDropDown(anchor, xoff, yoff);
-    } else {
-        pw.showAsDropDown(anchor, xoff, yoff);
-    }
-}
-```
-这两段代码的主要问题是，没有考虑虚拟按键的情况，屏幕的高度算的不一定对，或者有虚拟按键，虚拟按键是否显示都会影响屏幕的可用高度。所以问题的关键是算出屏幕真实的可用高度。
-
-为了方便以后复用，我们重新定义一个PopupWindowCompat继承自PopupWindow，具体代码如下，主要是综合考虑以上三种情况，和算出屏幕的真实可用高度，注释已经写的很清楚了吧，我就省点字了（偷懒）。
-
-获取屏幕真实总高度：
-
-```java
-public static int getScreenHeight(Activity activity) {
-        if (activity == null) {
-            return 0;
-        }
-        Display display = activity.getWindowManager().getDefaultDisplay();
-        int realHeight = 0;
-        if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
-            final DisplayMetrics metrics = new DisplayMetrics();
-            display.getRealMetrics(metrics);
-            realHeight = metrics.heightPixels;
-        } else {
-            try {
-                Method mGetRawH = Display.class.getMethod("getRawHeight");
-                realHeight = (Integer) mGetRawH.invoke(display);
-            } catch (Exception e) {
-                e.printStackTrace();
-            }
-        }
-        return realHeight;
-    }
-```
-
-检测是否具有底部导航栏
-
-```java
-	private static boolean checkDeviceHasNavigationBar(Activity activity) {
-        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
-            WindowManager windowManager = activity.getWindowManager();
-            Display display = windowManager.getDefaultDisplay();
-            DisplayMetrics realDisplayMetrics = new DisplayMetrics();
-            display.getRealMetrics(realDisplayMetrics);
-            int realHeight = realDisplayMetrics.heightPixels;
-            int realWidth = realDisplayMetrics.widthPixels;
-            DisplayMetrics displayMetrics = new DisplayMetrics();
-            display.getMetrics(displayMetrics);
-            int displayHeight = displayMetrics.heightPixels;
-            int displayWidth = displayMetrics.widthPixels;
-            return (realWidth - displayWidth) > 0 || (realHeight - displayHeight) > 0;
-        } else {
-            boolean hasNavigationBar = false;
-            Resources resources = activity.getResources();
-            int id = resources.getIdentifier("config_showNavigationBar", "bool", "android");
-            if (id > 0) {
-                hasNavigationBar = resources.getBoolean(id);
-            }
-            try {
-                Class systemPropertiesClass = Class.forName("android.os.SystemProperties");
-                Method m = systemPropertiesClass.getMethod("get", String.class);
-                String navBarOverride = (String) m.invoke(systemPropertiesClass, "qemu.hw.mainkeys");
-                if ("1".equals(navBarOverride)) {
-                    hasNavigationBar = false;
-                } else if ("0".equals(navBarOverride)) {
-                    hasNavigationBar = true;
-                }
-            } catch (Exception e) {
-            }
-            return hasNavigationBar;
-        }
-    }
+```groovy
+implementation 'com.jankin.popupwindowcompat:lib:1.0.1'
 ```
 
-有底部导航栏时，底部导航栏是否可见:
+## 使用
 
-```java
-private static boolean isNavigationBarVisible(Activity activity) {
-        boolean show = false;
-        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
-            Display display = activity.getWindow().getWindowManager().getDefaultDisplay();
-            Point point = new Point();
-            display.getRealSize(point);
-            View decorView = activity.getWindow().getDecorView();
-            Configuration conf = activity.getResources().getConfiguration();
-            if (Configuration.ORIENTATION_LANDSCAPE == conf.orientation) {
-                View contentView = decorView.findViewById(android.R.id.content);
-                show = (point.x != contentView.getWidth());
-            } else {
-                Rect rect = new Rect();
-                decorView.getWindowVisibleDisplayFrame(rect);
-                show = (rect.bottom != point.y);
-            }
-        }
-        return show;
-    }
-```
-
-
-获取底部导航栏真实高度：
-
-```java
-	/**
-     * 获取当前底部导航栏高度(隐藏后高度为0)
-     *
-     * @param activity
-     * @return
-     */
-     public static int getCurrentNavigationBarHeight(Activity activity) {
-        int navigationBarHeight = 0;
-        Resources resources = activity.getResources();
-        int resourceId = resources.getIdentifier(isPortrait(activity) ? "navigation_bar_height" : "navigation_bar_height_landscape", "dimen", "android");
-        if (resourceId > 0 && checkDeviceHasNavigationBar(activity) && isNavigationBarVisible(activity)) {
-            navigationBarHeight = resources.getDimensionPixelSize(resourceId);
-        }
-        return navigationBarHeight;
-    }
-```
+使用PopupWindowCompat替代PopupWindow，用法和PopupWindow一样。
 
-获取屏幕可用高度：
+## 效果图
 
-```java
-	/**
-     * 获取可用屏幕高度，排除虚拟键
-     *
-     * @param context 上下文
-     * @return 返回高度
-     */
-    public static int getContentHeight(Activity context) {
-        int contentHeight = getScreenHeight(context) - getCurrentNavigationBarHeight(context);
-        return contentHeight;
-    }
+![screenshot](screenshot.gif)
 
-```
-
-自定义的PopupWindowCompat的主要代码如下：
-
-```java
-	@Override
-    public void showAsDropDown(View anchor, int xoff, int yoff, int gravity) {
 
-        // 7.0 以下或者高度为WRAP_CONTENT, 默认显示
-        if (Build.VERSION.SDK_INT < 24 || getHeight() == ViewGroup.LayoutParams.WRAP_CONTENT) {
-            super.showAsDropDown(anchor, xoff, yoff, gravity);
-        } else {
-            if (getContentView().getContext() instanceof Activity) {
-                Activity activity = (Activity) getContentView().getContext();
-                int screenHeight;
-                // 获取屏幕真实高度, 减掉虚拟按键的高度
-                screenHeight = OsUtils.getContentHeight(activity);
-                int[] location = new int[2];
-                // 获取控件在屏幕的位置
-                anchor.getLocationOnScreen(location);
-                // 算出popwindow最大高度
-                int maxHeight = screenHeight - location[1] - anchor.getHeight();
-                // popupwindow  有具体的高度值，但是小于anchor下边缘与屏幕底部的距离， 正常显示
-                if(getHeight() > 0 && getHeight() < maxHeight){
-                    super.showAsDropDown(anchor, xoff, yoff, gravity);
-                }else {
-                    // match_parent 或者 popwinddow的具体高度值大于anchor下边缘与屏幕底部的距离， 都设置为最大可用高度
-                    setHeight(maxHeight);
-                    super.showAsDropDown(anchor, xoff, yoff, gravity);
-                }
 
-            }
-        }

+# PopupWindowCompat
+[![Build Status](https://travis-ci.com/wang0826jj/PopupWindowCompat.svg?branch=master)](https://travis-ci.com/wang0826jj/PopupWindowCompat) [![Bintray](https://api.bintray.com/packages/wang0826jj/maven/PopupWindowCompat/images/download.svg)](https://bintray.com/wang0826jj/maven/PopupWindowCompat/_latestVersion) [![GitHub license](https://img.shields.io/github/license/wang0826jj/PopupWindowCompat.svg)](https://github.com/wang0826jj/PopupWindowCompat/blob/master/LICENSE)
+
+## English | [中文](README.md)
+
+A compatible Popwindow adapt android 7.x , 8.x etc, Mainly adapts to the height of the full-screen problem after calling `popupWindow.showAsDropDown()` when setting the height to match_parent, and adapting whether there is a virtual button and whether the virtual button is displayed.
+
+## Adding to your project
+
+```groovy
+implementation 'com.jankin.popupwindowcompat:lib:1.0.1'
+```
+
+## Simple Usage
+
+Use PopupWindowCompat instead of PopupWindow, the same as PopupWindow.
