EditText: Disable Paste/Replace menu pop-up on Tex

Question

My goal is to have an EditText that has no fancy features, just the Text Selection Handler for moving the cursor more easily -- so no context menus or pop-ups.

I've disabled the appearance of the text editing function actionbar (copy/Paste etc.) by consuming the ActionMode Callback event, as per this solution.

The middle Middle Text Select Handle (see image below) still appears when text exists in the field and a click occurs within the text. Great! I want to keep this behaviour. What I DON'T want is the "PASTE" menu to appear when the Text Select Handle itself is clicked.

I have also disabled long-click input for the EditText by setting android:longClickable="false" in the styles XML. Disabling the long click prevents the "Paste/Replace" menu from appearing when the mouse is clicked and held (i.e. long touch), however when the mouse is clicked (single touch) within the text, the text selection handle appears, and when the text selection handle itself is clicked, then the "paste" menu option appears (when there's text in the clipboard). This is what I'm trying to prevent.

From what I can see from the source, the ActionPopupWindow is what pops up with the PASTE/REPLACE options. ActionPopupWindow is a protected variable (mActionPopupWindow) in the private abstract class HandleView within public class android.widget.Editor...

Short of disabling the clipboard service or editing the Android Source code, is there a way that I can prevent this from showing? I tried to define a new style for android:textSelectHandleWindowStyle, and set android:visibility to gone, but it didn't work (app froze for a while when it would otherwise have shown).

I don't find a way to hide the menu popup , But you can disable from pasting if user tap on the menu

Create a custom EditText and override the onTextContextMenuItem method and return false for android.R.id.paste and android.R.id.pasteAsPlainText menu id's.

@Override
public boolean onTextContextMenuItem(int id) {
    switch (id){
        case android.R.id.paste:
        case android.R.id.pasteAsPlainText:
            return false;

    }
    return super.onTextContextMenuItem(id);
}

Found another solution when the blue view (insertion controller) is not appeared at all. I used reflection to set target boolean field of Editor class. Look at the android.widget.Editor and android.widget.TextView for more details.

Add the following code into your custom EditText (with all previous code in this topic):

@Override
public boolean onTouchEvent(MotionEvent event) {
    if (event.getAction() == MotionEvent.ACTION_DOWN) {
        // setInsertionDisabled when user touches the view
        this.setInsertionDisabled();
    }
    return super.onTouchEvent(event);
}

/**
 * This method sets TextView#Editor#mInsertionControllerEnabled field to false
 * to return false from the Editor#hasInsertionController() method to PREVENT showing
 * of the insertionController from EditText
 * The Editor#hasInsertionController() method is called in  Editor#onTouchUpEvent(MotionEvent event) method.
 */

private void setInsertionDisabled() {
    try {
        Field editorField = TextView.class.getDeclaredField("mEditor");
        editorField.setAccessible(true);
        Object editorObject = editorField.get(this);

        Class editorClass = Class.forName("android.widget.Editor");
        Field mInsertionControllerEnabledField = editorClass.getDeclaredField("mInsertionControllerEnabled");
        mInsertionControllerEnabledField.setAccessible(true);
        mInsertionControllerEnabledField.set(editorObject, false);
    }
    catch (Exception ignored) {
        // ignore exception here
    }
}

Also, maybe you can find the better place than onTouch() to call the target method.

Just override one method:

@Override
protected MovementMethod getDefaultMovementMethod() {
    // we don't need arrow key, return null will also disable the copy/paste/cut pop-up menu.
    return null;
}

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) {}
    }
} 

I've tested this in Android v4.4.2 and v4.4.3.

Answer 5

I found a simple yet reliable way. The idea is the consume away the touch event, to prevent the touch event reach underlining default code.

1. To disable copy/paste popup.
2. To disable text selection handler.
3. Still showing cursor at end of text.
4. Still showing keyboard.

---

maskedEditText.setOnTouchListener(new View.OnTouchListener() {
    @Override
    public boolean onTouch(View view, MotionEvent motionEvent) {
        focusAndShowKeyboard(view.getContext(), maskedEditText);
        // Consume the event.
        return true;
    }
});

private static void focusAndShowKeyboard(Context context, EditText editText) {
    editText.requestFocus();
    InputMethodManager imm = (InputMethodManager) context.getSystemService(Context.INPUT_METHOD_SERVICE);
    imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, InputMethodManager.HIDE_IMPLICIT_ONLY);
}

Note, blinking cursor is still showing at end of text. Just that the screenshot unable to capture it.

Answer 6

None of the above solutions worked for me. I've managed to do my solution (explanation after), which disabled pasting anything on the EditText while maintaining all other operations valid.
Mainly, you have to override this method on your implementation of EditText:

@Override
public boolean onTextContextMenuItem (int id) {
    if (id == android.R.id.paste) return false;

    return super.onTextContextMenuItem(id);
}

So investigating EditText code, after all checks, paste (and all ContextMenu actions on the EditText) happen at a method called onTextContextMenuItem:

public boolean onTextContextMenuItem(int id) {
    int min = 0;
    int max = mText.length();

    if (isFocused()) {
        final int selStart = getSelectionStart();
        final int selEnd = getSelectionEnd();

        min = Math.max(0, Math.min(selStart, selEnd));
        max = Math.max(0, Math.max(selStart, selEnd));
    }

    switch (id) {
        case ID_SELECT_ALL:
            // This does not enter text selection mode. Text is highlighted, so that it can be
            // bulk edited, like selectAllOnFocus does. Returns true even if text is empty.
            selectAllText();
            return true;

        case ID_PASTE:
            paste(min, max);
            return true;

        case ID_CUT:
            setPrimaryClip(ClipData.newPlainText(null, getTransformedText(min, max)));
            deleteText_internal(min, max);
            stopSelectionActionMode();
            return true;

        case ID_COPY:
            setPrimaryClip(ClipData.newPlainText(null, getTransformedText(min, max)));
            stopSelectionActionMode();
            return true;
    }
    return false;
}

If you notice, pasting will only occur when id == ID_PASTE, so, again, looking at the EditText code:

static final int ID_PASTE = android.R.id.paste;
