Can't delete image in contenteditable div on Android

Question

I am building a rich text editor in android. To do so, I am using a webView with a contentEditable div.

To add styles, I invoke JavaScrip

Answer 1

I use this to do a rich editor in a webview

Then override method TapInputConnection in Webview

@Override
public InputConnection onCreateInputConnection(EditorInfo outAttrs) {
    return new TapInputConnection(super.onCreateInputConnection(outAttrs));
}



class TapInputConnection implements InputConnection {

    private InputConnection mConnection;


    public TapInputConnection(InputConnection conn){
        this.mConnection = conn;
    }

    @Override
    public CharSequence getTextBeforeCursor(int n, int flags) {
        return mConnection.getTextBeforeCursor(n, flags);
    }

    @Override
    public CharSequence getTextAfterCursor(int n, int flags) {
        return mConnection.getTextAfterCursor(n, flags);
    }

    @Override
    public CharSequence getSelectedText(int flags) {
        return mConnection.getSelectedText(flags);
    }

    @Override
    public int getCursorCapsMode(int reqModes) {
        return mConnection.getCursorCapsMode(reqModes);
    }

    @Override
    public ExtractedText getExtractedText(ExtractedTextRequest request, int flags) {
        return mConnection.getExtractedText(request, flags);
    }

    @Override
    public boolean deleteSurroundingText(int beforeLength, int afterLength) {
        return mConnection.deleteSurroundingText(beforeLength, afterLength);
    }

    @Override
    public boolean setComposingText(CharSequence text, int newCursorPosition) {
        return mConnection.setComposingText(text, newCursorPosition);
    }

    @Override
    public boolean setComposingRegion(int start, int end) {
        return mConnection.setComposingRegion(start, end);
    }

    @Override
    public boolean finishComposingText() {
        return mConnection.finishComposingText();
    }

    @Override
    public boolean commitText(CharSequence text, int newCursorPosition) {
        return mConnection.commitText(text, newCursorPosition );
    }

    @Override
    public boolean commitCompletion(CompletionInfo text) {
        return mConnection.commitCompletion(text);
    }

    @Override
    public boolean commitCorrection(CorrectionInfo correctionInfo) {
        return mConnection.commitCorrection(correctionInfo);
    }

    @Override
    public boolean setSelection(int start, int end) {
        return mConnection.setSelection(start, end);
    }

    @Override
    public boolean performEditorAction(int editorAction) {
        return mConnection.performEditorAction(editorAction);
    }

    @Override
    public boolean performContextMenuAction(int id) {
        return mConnection.performContextMenuAction(id);
    }

    @Override
    public boolean beginBatchEdit() {
        return mConnection.beginBatchEdit();
    }

    @Override
    public boolean endBatchEdit() {
        return mConnection.endBatchEdit();
    }

    @Override
    public boolean sendKeyEvent(KeyEvent event) {
        if (event.getKeyCode() == KeyEvent.KEYCODE_DEL) {
            if (event.getAction() == KeyEvent.ACTION_UP) {
                delete();
            }
            return true;
        }
        return mConnection.sendKeyEvent(event);
    }

    @Override
    public boolean clearMetaKeyStates(int states) {
        return false;
    }

    @Override
    public boolean reportFullscreenMode(boolean enabled) {
        return mConnection.reportFullscreenMode(enabled);
    }

    @Override
    public boolean performPrivateCommand(String action, Bundle data) {
        return mConnection.performPrivateCommand(action, data);
    }

    @TargetApi(Build.VERSION_CODES.LOLLIPOP)
    @Override
    public boolean requestCursorUpdates(int cursorUpdateMode) {
        return mConnection.requestCursorUpdates(cursorUpdateMode);
    }
}

You have realized that I override sendKeyEvent and I deal with Delete Key by myself

This is the delete() function;

public void delete(){
  loadurl("javascript:document.execCommand('delete', false, null);");
}
