在点击外部或后退按钮时关闭弹出窗口
Close PopupWindow upon tapping outside or back button
我想通过点击 window 外部或按后退按钮来关闭 PopupWindow。现在你可以点击屏幕上的任意位置，然后 window 关闭，我不明白为什么。我还想给 PopupWindow 添加一个阴影。谢谢！

抱歉这个菜鸟问题。我已经有一段时间了，无论我尝试多少，我似乎都无法弄清楚......我最大的两个担忧是在弹出 window 后面隐藏阴影并在按后退按钮或在弹出窗口外点击 window。首先十分感谢。谢谢。
您将需要使用 Outside touch 设置 Background Drawable true
popWindow.setFocusable(true);
popupWindow.setBackgroundDrawable(new ColorDrawable())
popupWindow.setOutsideTouchable(true);
方法通过传递任何 drawable。否则整个屏幕都是你的背景，点击外面将不起作用 backPressed 将使用这种方式自动工作！
要给你添加阴影 PopupWindow 更简单的方法是将 CardView 作为 xml 中 View 的根并更改 elevation属性。要使用 CardView，您可能还需要在 gradle 文件中添加一个依赖项
<android.support.v7.widget.CardView
xmlns:card_view="http://schemas.android.com/apk/res-auto"
android:id="@+id/card_view"
android:layout_gravity="center"
android:layout_width="200dp"
android:layout_height="200dp"
card_view:cardElevation="4dp"
card_view:cardCornerRadius="4dp">
<!--YOUR RELATIVE LAYOUT SHOULD BE HERE!-->
</android.support.v7.widget.CardView>
您还必须在 app gradle 文件中添加依赖项，例如：
dependencies {
...
compile 'com.android.support:cardview-v7:21.0.+'
}
CardView and elevation here 中有更多详细信息。
我的代码是这样的
LayoutInflater layoutInflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
// inflate the custom popup layout
final View inflatedView = layoutInflater.inflate(R.layout.pop_up_test, null,false);
// get device size
Display display = getWindowManager().getDefaultDisplay();
final Point size = new Point();
display.getSize(size);
//mDeviceHeight = size.y; //Not in use just comment it off for now
// set height depends on the device size
popupWindow = new PopupWindow(inflatedView, size.x - 50,(WindowManager.LayoutParams.WRAP_CONTENT), true );
// set a background drawable with rounders corners
// make it focusable to show the keyboard to enter in `EditText`
popupWindow.setFocusable(true);
popupWindow.setBackgroundDrawable(new ColorDrawable());//This has no meaning than dismissal of the Pop Up Noni!!
// make it outside touchable to dismiss the popup window
popupWindow.setOutsideTouchable(true);
// show the popup at bottom of the screen and set some margin at bottom ie,
popupWindow.showAtLocation(v, Gravity.BOTTOM, 0,100);
我可以在您的 Activity 中覆盖您的 onBackPressed() 方法。话虽如此，如果您按下后退按钮，则会触发此方法。在该方法中，您可以检查弹出窗口是否显示，并在需要时关闭它，如下所示：
@Override
public void onBackPressed() {
if (popupWindow != null && popupWindow.isShowing()) {
popupWindow.dismiss();
}
super.onBackPressed();
}
您还可以使用您希望用户单击以取消弹出窗口的区域中的一些 onClickListeners 来实现 dismiss() 逻辑。
如果您出于任何原因不想使用 Xenolion asnwer，您可以手动创建覆盖整个屏幕的背景。
在上面添加任何内容。
在关闭背景和 window 的背景上添加 onclick 侦听器。
在 popupwindow 上添加 onclick 侦听器为 null，这将防止在其顶部单击时关闭弹出窗口。

关闭 window
popup.setOnClickListener(null);
我有一些弹出窗口不会被后退按钮关闭或在 Android 5 上点击外部。我在较新的 Android 版本上工作得很好，只是在 Android 上不行 5，棒棒糖，API 21 级。
我的情况只需要：
popupWindow.setBackgroundDrawable(new ColorDrawable())
去看看吧！
