Can a Context Menu open an Image View?

Question

Attention: This question is different and is not an exact duplicate. This states that the image needs to pop up without a dialog. No one even bothered going through this question to see if it was a duplicate which it is not.

I am trying to open an Image View from my context menu, however, I do not know how to do this. When an item in the Context Menu is clicked, I need an Image View to appear. Is it even possible to open an Image View from a Context Menu? People have recommended using a dialog instead, but I want to know if this specific way is possible. Thank you in advance. Here is my code:

package com.carouseldemo.main;

import android.app.Activity;


import android.os.Bundle;
import android.view.ContextMenu;
import android.view.ContextMenu.ContextMenuInfo;
import android.view.Menu;
import android.view.MenuItem;

import android.view.MenuInflater;
import android.view.View;
import android.widget.ImageView;
import android.widget.TextView;
import android.widget.Toast;

import com.carouseldemo.controls.Carousel;
import com.carouseldemo.controls.CarouselAdapter;
import com.carouseldemo.controls.CarouselAdapter.AdapterContextMenuInfo;
import com.carouseldemo.controls.CarouselAdapter.OnItemClickListener;
import com.carouseldemo.controls.CarouselAdapter.OnItemSelectedListener;
import com.carouseldemo.controls.CarouselItem;

public class MainActivity extends Activity {


    @Override
      public boolean onContextItemSelected(MenuItem item) {
            int id = item.getItemId(); // you know which menu is clicked
            ImageView popup = new ImageView(this);
        //set the image 
            popup.setImageResource(R.drawable.cat); // or setImageBitmap ,
                                                            // or setImageUti etc
        // this will make the ImageView fill the entire content area. If you don't want this wrap it with another layout
            ((FrameLayout) findViewById(android.R.id.content)).addView(popup);
            return super.onContextItemSelected(item);
        }


    @Override

    super.onCreateOptionsMenu(menu);

I want an image to pop up after clicking on an item in the Context Menu. — Lulu R, Feb 06 '13 at 16:37
No. I said in this question I want to know how to do it without a dialog. I want to know if it is possible to open an image from a context menu. The question before hand was not answered at all, it just recommended a different way. I need to know if this specific way is possible and how. — Lulu R, Feb 07 '13 at 04:24
This is not a duplicate. Wow, I can't believe some people don't even bother reading here. — Lulu R, Feb 07 '13 at 14:03
Your question is a duplicate. In this one you ask about hot to popup an `ImageView` without using a dialog, and in the initial question you ask the same, about how to popup the ImageView(and when you receive an answer to use a dialog you say that isn't the way you wanted, so in that question you were already looking for a solution without the use of a dialog). Not to mention that half of the question's text is identical + the code posted. In `onContextItemSelected` create the `ImageView`, assign its image and add it to the view with the id `android.R.id.content`. — user, Feb 07 '13 at 14:31
The question was not answered properly before. So I asked again because I need to get this done, there were plenty of views but no answers. Do you mean something like this? public void onContextItemSelected (ContextMenu menu, View v, ContextMenuInfo menuInfo){ ImageView imageView = new ImageView(context); ImageView.setImage(R.drawable.cat); imageView.setVisibility(View.VISIBLE); } — Lulu R, Feb 07 '13 at 14:55
Even though (context) cannot be resolved to a variable and the method setImage is undefined or the type ImageView. — Lulu R, Feb 07 '13 at 14:57
Something like this https://gist.github.com/luksprog/4731481 . You should have a reference to the Context as you are in an activity. — user, Feb 07 '13 at 15:07
It says FrameLayout cannot be resolved to a type. Thank you for helping me so far. I have updated the code in my question with the code you have given me. Am I not placing the code in the right spot? — Lulu R, Feb 07 '13 at 15:23
It's in the right spot. Did you imported the class From the `FrameLayout`(import android.widget.FrameLayout;) like you did for the TextView, ImageView etc? — user, Feb 07 '13 at 15:46
Thank you. Now there's just two more things please. How can I make different images pop up when I select other items in the context menu? Right now, one picture shows up when I select one item in the context menu. How can I get a different picture to show up when I click different item in the context menu? The second thing is how to close the image view, as the picture is stuck on the screen and won't go away. — Lulu R, Feb 07 '13 at 15:54

How to popup the ImageView I've shown you in the comment posted.

How can I make different images pop up when I select other items in the context menu? Right now, one picture shows up when I select one item in the context menu. How can I get a different picture to show up when I click different item in the context menu?

Don't add your menu options using this menu.add("Product 1");. Instead use this option:

menu.add(Menu.NONE, 1, Menu.None, "menu title");

Instead of the 1 value, the second parameter, pass a unique value for each menu item that you add to the ContextMenu. In the onContextItemSelected method you can then use item.getItemId(); to get the id of the menu that was clicked and based on that you'll know which item was clicked. Assign the image based on that item's id.

The second thing is how to close the image view, as the picture is stuck on the screen and won't go away.

Assign to the ImageView that you create an OnClickListener or OnTouchListener and in the listener's method remove the ImageView:

ImageView popup = new ImageView(this);    
popup.setOnClickListener(new OnClickListener() {

     @Override
     public void onClick(View v) {
         ((FrameLayout) findViewById(android.R.id.content)).removeView(v);
     } 
});

I have the idea of what you're saying but cannot implement it right. https://gist.github.com/nixjust/c64c0ecc6d49506dde93 That is the code I have now. I cannot assign the id of the menu properly, and I'm not sure if everything is in the right place. The second image I am trying to open is rabbit, from menu id 2. Can you take a look and show me what I'm doing wrong? – Lulu R Feb 07 '13 at 16:46
The original code before I changed it can always be viewed in my question, just for reference if it helps. – Lulu R Feb 07 '13 at 16:49
Update: The image does disappear when clicked. So that is working. But I cannot assign the menu id properly. – Lulu R Feb 07 '13 at 16:53

@LuluR I've edited the gist, check it out https://gist.github.com/luksprog/5a6dd3e7f901a5d32cb5 – user Feb 07 '13 at 17:52
Thank you! You've really helped me. I've been searching for a solution for over a week. Again, thank you for all your help. – Lulu R Feb 07 '13 at 18:48
