如何在android中禁用复制粘贴

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

public class CustomEditText extends EditText {
    public CustomEditText(Context context) {
        super(context);
        init();
    }

    public CustomEditText(Context context, AttributeSet attrs) {
        super(context, attrs);
        init();
    }

    public CustomEditText(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        init();
    }

    private void init() {
        // 禁用文本选择功能
        setCustomSelectionActionModeCallback(new ActionMode.Callback() {
            @Override
            public boolean onCreateActionMode(ActionMode mode, Menu menu) {
                return false;
            }

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

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

            @Override
            public void onDestroyActionMode(ActionMode mode) {

            }
        });
    }

    @Override
    public boolean onTextContextMenuItem(int id) {
        // 禁用复制粘贴功能
        if (id == android.R.id.cut || id == android.R.id.paste) {
            return false;
        }
        return super.onTextContextMenuItem(id);
    }
}

<com.example.app.CustomEditText
    android:layout_width="match_parent"
    android:layout_height="wrap_content" />
