PopUpWindow in Android

PopUpWindow in Android

 

Android supports Popup Window like in IPhone. The difference between pop up window and dialog is we have to set the position (like center, top, bottom...) and also x and y positions. The below snippets explains the way.

 Home.java:

package com.popup.activities;

import android.app.Activity;
import android.os.Bundle;
import android.view.Gravity;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup.LayoutParams;
import android.widget.Button;
import android.widget.PopupWindow;

public class Home extends Activity
{
    private Button btnShowPopUp;
    private PopupWindow mpopup;
       
    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
       
        btnShowPopUp = (Button)findViewById(R.id.btnShowPopUp);
       
        btnShowPopUp.setOnClickListener(new OnClickListener()
        {           
            @Override
            public void onClick(View arg0)
            {
                View popUpView = getLayoutInflater().inflate(R.layout.popup, null); // inflating popup layout
                mpopup = new PopupWindow(popUpView, LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT, true); //Creation of popup
                mpopup.setAnimationStyle(android.R.style.Animation_Dialog);  
                mpopup.showAtLocation(popUpView, Gravity.BOTTOM, 0, 0);    // Displaying popup
               
                Button btnOk = (Button)popUpView.findViewById(R.id.btnOk);
                btnOk.setOnClickListener(new OnClickListener()
                {                   
                    @Override
                    public void onClick(View v)
                    {
                        mpopup.dismiss();  //dismissing the popup
                    }
                });
               
                Button btnCancel = (Button)popUpView.findViewById(R.id.btnCancel);
                btnCancel.setOnClickListener(new OnClickListener()
                {                   
                    @Override
                    public void onClick(View v)
                    {
                        mpopup.dismiss(); dismissing the popup
                    }
                });
            }
        }); 
    }
}

main.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
  
    <Button
        android:layout_width="wrap_content"
        android:id="@+id/btnShowPopUp"
        android:text="ShowPopUp"
        android:layout_height="wrap_content">
    </Button>
  
</LinearLayout>
popup.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent"
  android:orientation="vertical"
  android:background="#90FFFFFF"
  android:layout_height="wrap_content">
 
  <TextView
      android:layout_width="fill_parent"
      android:text="PopUp Window"
      android:textColor="#000000"
      android:gravity="center"
      android:textStyle="bold"
      android:layout_height="wrap_content">
  </TextView>
 
  <Button
      android:layout_width="fill_parent"
      android:id="@+id/btnOk"
      android:text="Ok"
      android:layout_height="wrap_content">
  </Button>
 
  <Button
      android:layout_width="fill_parent"
      android:id="@+id/btnCancel"
      android:text="Cancel"
      android:layout_height="wrap_content">
  </Button>
 
</LinearLayout>
