EditText how to activate copy/paste popup without any actionbar?

Question

I m under delphi and i use the android framework to create an edit. When i set the theme to Theme.DeviceDefault.Light.NoActionBar then i can select some text in my EditText and i have a popup with "select all/cut/copy/paste/etc" like you can see on the picture below.

However, when i select Theme.Material.Light.NoActionBar or Theme.Holo.Light.NoActionBar then i can't select any text in my EditText (i have no right or left text selection handles) and off course i don't have any copy/paste popup

Is their any way to have this copy/paste popup on Theme_Material_Light_NoActionBar ?

Theme.DeviceDefault.Light.NoActionBar

Theme_Material_Light_NoActionBar

Theme.Holo.Light.NoActionBar

NOTE 1:

When i move the screen to the horizontal then the edittext take all the available space, and then i can see my right and left text selection handles like on the picture below, but i think it's because theme swap to Theme.DeviceDefault.Light.NoActionBar when i move the screen to the horizontal but i m not sure :

NOTE 2:

On my editText, when i do setCustomSelectionActionModeCallback(new Callback() {}) then the Callback is never called :( this is not normal i think ? What in the editText can forbid the callback ?

NOTE 2:

I can select text in all theme (but i can't copy it off course), but except in Theme.DeviceDefault.Light.NoActionBar i can't see the right and left text selection handle.

NOTE 3:

Theme.DeviceDefault.Light.NoActionBar show the right and left text selection handle only on some phones like the samsung galaxy. On some other it's didn't work.

NOTE 4:

i found partially the source of the problem! it's because i create my view via the WindowManager.addView(view, layout_params) and in this way startactionmodeforChild return null and this forbid the actionbar and the text selection handles to be show. Now if i do something like this in my edittext :

@Override
public ActionMode startActionMode(ActionMode.Callback callback) {
    Activity host = (Activity) this.getContext();    
    return host.getWindow().getDecorView().startActionMode(callback); 
} 

then i can see the right and left text action handles (but not on marshmallow, it's work only on lollipop this i don't know why). My problem now is that the actionbar is showed, but it's showed empty :( nothing is draw inside (but i can see that the cut/copy/past control are inside in the dump view hierarchie). So now i m not looking for a way to replace this actionbar by a popup menu instead (like on the picture Theme.DeviceDefault.Light.NoActionBar). Any idea ?

Answer 1

add following in your activity

ActionMode mActionMode;

and you have to create an ActionMondeCallback interface

class ActionBarCallback implements ActionMode.Callback
    {

        @Override
        public boolean onCreateActionMode(ActionMode mode, Menu menu) {
            mode.getMenuInflater().inflate(R.menu.contextual_menu, menu);
            return true;
        }

        @Override
        public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
            return false;
        }

        @Override
        public boolean onActionItemClicked(ActionMode mode, MenuItem item) {

            int id = item.getItemId();
            if(id == R.id.item_delete)
            {
                tv.setText("");
                Toast.makeText(MainActivity.this,"option deleted",Toast.LENGTH_LONG);
            }
            return false;
        }

        @Override
        public void onDestroyActionMode(ActionMode mode) {

        }
    }

where contextual_menu.xml is as follows with required icons

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    tools:context="com.example.letschat"
    >
    <item
        android:id="@+id/item_search"
        android:icon="@android:drawable/ic_menu_search"
        app:showAsAction="ifRoom|withText"
        android:title="Delete"
        android:titleCondensed="Delete">
    </item>
    <item
        android:id="@+id/item_delete"
        android:icon="@android:drawable/ic_menu_delete"
        app:showAsAction="ifRoom|withText"
        android:title="Delete"
        android:titleCondensed="Delete">
    </item>
    <item
        android:id="@+id/item_share"
        android:icon="@android:drawable/ic_menu_share"
        app:showAsAction="ifRoom|withText"
        android:title="Delete"
        android:titleCondensed="Delete">
    </item>
</menu>

Now Enable your Contextual ActionBar(CAB) As follows as for example here am are enabling on long click of a textview

yourtextView.setOnLongClickListener(new View.OnLongClickListener() {
            @Override
            public boolean onLongClick(View v) {
                mActionMode = MainActivity.this.startActionMode(new ActionBarCallback());
                return true;
            }
        });

then you have to write your own action on click on each action event on CAB.

For API level 11 or above then you can stop copy,paste,cut and custom context menus from appearing by.

edittext.setCustomSelectionActionModeCallback(new ActionMode.Callback() {

        public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
            return false;
        }

        public void onDestroyActionMode(ActionMode mode) {                  
        }

        public boolean onCreateActionMode(ActionMode mode, Menu menu) {
            return false;
        }

        public boolean onActionItemClicked(ActionMode mode, MenuItem item) {
            return false;
        }
    });

Returning false from onCreateActionMode(ActionMode, Menu) will prevent the action mode from being started(Select All, Cut, Copy and Paste actions).

Solution: Override isSuggestionsEnabled and canPaste in EditText.

For the quick solution, copy the class below - this class overrides the EditText class, and blocks all events accordingly.

For the gritty details, keep reading.

The solution lies in preventing PASTE/REPLACE menu from appearing in the show() method of the (non-documented) android.widget.Editor class. Before the menu appears, a check is done to if (!canPaste && !canSuggest) return;. The two methods that are used as the basis to set these variables are both in the EditText class:

isSuggestionsEnabled() is public, and may thus be overridden. canPaste() is not, and thus must be hidden by introducing a function of the same name in the derived class. So incorporating these updates into a class that also has the setCustomSelectionActionModeCallback, and the disabled long-click, here is the full class to prevent all editing (but still display the text selection handler) for controlling the cursor:

package com.cjbs.widgets;

import android.content.Context;
import android.util.AttributeSet;
import android.view.ActionMode;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.EditText;


/**
 *  This is a thin veneer over EditText, with copy/paste/spell-check removed.
 */
public class NoMenuEditText extends EditText

{
    private final Context context;

    /** This is a replacement method for the base TextView class' method of the same name. This 
     * method is used in hidden class android.widget.Editor to determine whether the PASTE/REPLACE popup
     * appears when triggered from the text insertion handle. Returning false forces this window
     * to never appear.
     * @return false
     */
    boolean canPaste()
    {
       return false;
    }

    /** This is a replacement method for the base TextView class' method of the same name. This method
     * is used in hidden class android.widget.Editor to determine whether the PASTE/REPLACE popup
     * appears when triggered from the text insertion handle. Returning false forces this window
     * to never appear.
     * @return false
     */
    @Override
    public boolean isSuggestionsEnabled()
    {
        return false;
    }

    public NoMenuEditText(Context context)
    {
        super(context);
        this.context = context;
        init();
    }

    public NoMenuEditText(Context context, AttributeSet attrs)
    {
        super(context, attrs);
        this.context = context;
        init();
    }

    public NoMenuEditText(Context context, AttributeSet attrs, int defStyle)
    {
        super(context, attrs, defStyle);
        this.context = context;
        init();
    }

    private void init()
    {
        this.setCustomSelectionActionModeCallback(new ActionModeCallbackInterceptor());
        this.setLongClickable(false);
    }


    /**
     * Prevents the action bar (top horizontal bar with cut, copy, paste, etc.) from appearing
     * by intercepting the callback that would cause it to be created, and returning false.
     */
    private class ActionModeCallbackInterceptor implements ActionMode.Callback
    {
        private final String TAG = NoMenuEditText.class.getSimpleName();

        public boolean onCreateActionMode(ActionMode mode, Menu menu) { return false; }
        public boolean onPrepareActionMode(ActionMode mode, Menu menu) { return false; }
        public boolean onActionItemClicked(ActionMode mode, MenuItem item) { return false; }
        public void onDestroyActionMode(ActionMode mode) {}
    }
}

Try to use theme Theme.AppCompat.Light.NoActionBar.
Also set android:textIsSelectable="true" on your EditText in xml file.
