This example implement OnTouchListener() for PopupWindow to detect user action of drag-and-drop, to move PopupWindow.

Movable PopupWindow

package com.example.androidpopupwindow;

import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.MotionEvent;
import android.view.View;
import android.view.View.OnTouchListener;
import android.view.ViewGroup.LayoutParams;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.PopupWindow;
import android.widget.Spinner;
import android.app.Activity;

public class MainActivity extends Activity {
 
 String[] DayOfWeek = {"Sunday", "Monday", "Tuesday", 
   "Wednesday", "Thursday", "Friday", "Saturday"};

 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);

  final Button btnOpenPopup = (Button) findViewById(R.id.openpopup);
  btnOpenPopup.setOnClickListener(new Button.OnClickListener() {

   @Override
   public void onClick(View arg0) {
    LayoutInflater layoutInflater = 
      (LayoutInflater)getBaseContext()
      .getSystemService(LAYOUT_INFLATER_SERVICE);
    View popupView = layoutInflater.inflate(R.layout.popup, null);
    final PopupWindow popupWindow = new PopupWindow(
      popupView, LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
    
    Button btnDismiss = (Button)popupView.findViewById(R.id.dismiss);
    
    Spinner popupSpinner = (Spinner)popupView.findViewById(R.id.popupspinner);
    
    ArrayAdapter<String> adapter = 
      new ArrayAdapter<String>(MainActivity.this, 
        android.R.layout.simple_spinner_item, DayOfWeek);
    adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    popupSpinner.setAdapter(adapter);
    
    btnDismiss.setOnClickListener(new Button.OnClickListener(){

     @Override
     public void onClick(View v) {
      popupWindow.dismiss();
     }});
    
    popupWindow.showAsDropDown(btnOpenPopup, 50, -30);
    
    popupView.setOnTouchListener(new OnTouchListener() {
     int orgX, orgY;
     int offsetX, offsetY;

     @Override
     public boolean onTouch(View v, MotionEvent event) {
      switch (event.getAction()) {
      case MotionEvent.ACTION_DOWN:
       orgX = (int) event.getX();
       orgY = (int) event.getY();
       break;
      case MotionEvent.ACTION_MOVE:
       offsetX = (int)event.getRawX() - orgX;
       offsetY = (int)event.getRawY() - orgY;
       popupWindow.update(offsetX, offsetY, -1, -1, true);
       break;
      }
      return true;
     }});
   }

  });
 }

This official app can backup photos as well. Another backup and restore tool is KIES which is provided by Samsung. The lovely KIES can helop you bakcup phone data to computer, I think it is safer to store data in computer.

However, I need other way to do Samsung Galaxy deleted photos recovery

Unfortunately, when I accidetanlly deleted photos from Samsung Galaxy S4, I couldn't find backup anywhere, I didn't do backup for deleted photos before. Thus, I needed another ways.

So many twists and turns in my life. When I think I had had not chance to restore Samsung Galaxy deleted photos. I found another ways that I metioned it as the fastest way above.

There is no doubt that, I got a recovery softwar for Android.

Last example display "PopupWindow with transparent background". I want to have transparent background with visible border. This example create background with custom shape, have rounded border, semi-transparent background.

Popup Window with background of custom shape

Create /res/drawable/customborder.xml to define custom shape.

<shape xmlns:android="http://schemas.android.com/apk/res/android"
       android:shape="rectangle">
  <corners
      android:topLeftRadius="0dp"
      android:topRightRadius="30dp"
      android:bottomRightRadius="30dp"
      android:bottomLeftRadius="30dp" />
  <stroke
      android:width="3dp"
      android:color="@android:color/background_dark" />
  <solid 
      android:color="#800000c0"/>
</shape>

Modify /res/layout/popup.xml to define android:background="@drawable/customborder".

<?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:background="@drawable/customborder"
    android:orientation="vertical" >

    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_margin="1dp"
        android:orientation="vertical" >
        
        <LinearLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_margin="20dp"
            android:orientation="vertical" >

            <TextView
                android:layout_width="fill_parent"
                android:layout_height="wrap_content"
                android:text="It's a PopupWindow" />

            <ImageView
                android:layout_width="fill_parent"
                android:layout_height="wrap_content"
                android:src="@drawable/ic_launcher" />

            <Spinner
                android:id="@+id/popupspinner"
                android:spinnerMode="dialog"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content" />

            <Button
                android:id="@+id/dismiss"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content"
                android:text="Dismiss" />
