Android Popup Window Animation Example

The android.widget.PopupWindow class is another class that provides a popup window function besides AlertDialog. There is something different between them. This example will show you how to use the android.widget.PopupWindow in the android application.

1. PopupWindow And AlertDialog Difference.

  1. The main difference between AlertDialog and PopupWindow is the location of the display. The AlertDialog is fixed display on the screen, while PopupWindow can be displayed anywhere on the main screen.
  2. PopupWindow is a pop-up control that can be used to display any View and float at the top of the activity.
  3. Through PopupWindow we can achieve a variety of pop-up window effects such as information display or UI interaction.
  4. The PopupWindow custom layout is more convenient, and the display position is freedom there is no restriction.

2. PopupWindow Methods.

2.1 PopupWindow Constructor Method.

  1. public PopupWindow (Context context).
  2. public PopupWindow(View contentView) .
  3. public PopupWindow(View contentView, int width, int height) .
  4. public PopupWindow(View contentView, int width, int height, boolean focusable)
  5. Please Note: There are four constructors, but the basic three parameters for generating a PopupWindow must be set are: View contentView, int width, int height; You can’t pop a PopupWindow without any one of them!
  6. So, if you use the first constructor, the complete construct code should look like this.
    View popupContentView = LayoutInflater.from(ActivityClass.this).inflate(R.layout.popup_view_Layout, null); 
    PopupWindwo popupWindow = PopupWindow(context); 
    popupWindow.setContentView(popupContentView); 
    popupWindow.setWidth(ViewGroup.LayoutParams.WRAP_CONTENT); 
    popupWindow.setHeight(ViewGroup.LayoutParams.WRAP_CONTENT);

2.2 PopupWindow Display Methods.

  1. showAsDropDown(View anchorView): Show popup at the position of the relative control (lower left), no deviation.
  2. showAsDropDown(View anchorView, int xOffSet, int yOffSet): Show popup at the position of the relative control. xOffSet represents the offset of the x-axis, positive to the left, negative to the right. yOffSet represents the offset of the y-axis, positive to the down, negative to the up.
  3. showAtLocation(View parentView, int gravity, int xOffSet, int yOffSet): Show popup at the location specified by the gravity value. ( Gravity.CENTER, Gravity.BOTTOM) etc.

2.3 PopupWindow Other Methods.

  1. public void dismiss(): Close popup window when needed.
  2. public void setFocusable(boolean focusable): Let PopupWindow get the focus, then it will be able to handle the click event of the physical button, otherwise the event will be passed up by the Activity. If there is an Editor in PopupWindow, the focusable value must be true.

2.4 Add Animation To PopupWindow.

  1. PopupWindow.setAnimationStyle(R.style.ContextMenuAnim) can be used to add animation to a popup window.
    popupWindow.setAnimationStyle(R.style.popup_window_animation_phone);
  2. The above popup_window_animation_phone is a style defined in app / res / values / styles.xml file.
    <style name="popup_window_animation_phone">
        <item name="android:windowEnterAnimation">@android:anim/fade_in_animation</item>
    </style>
  3. The fade_in_animation and fade_out_animation are also custom-defined animation XML file saved under app / res / animator folder.
  4. fade_in_animation.xml
    <set xmlns:android="http://schemas.android.com/apk/res/android">
    
        <alpha
            android:duration="1500"
            android:fromAlpha="0.1"
            android:toAlpha="1" />
    
    </set>
  5. Below are the create animation XML file steps.
  6. Right-click the app/res folder.
  7. Click New —> Android resource file menu item in the popup menu list.
  8. Input the File name and choose Animator in the Resource type drop-down list.
