如何为editText视图禁用，粘贴，全选

Question

我有一个登录片段。对于密码（Edittext），我需要禁用粘贴并选择所有选项。

我尝试了setCustomSelectionActionModeCallback 和“set longClickable”，但它们不起作用。 任何建议提前谢谢

Answer 1

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;
            }
        });

从 onCreateActionMode(ActionMode, Menu) 返回 false 将阻止启动操作模式（全选、剪切、复制和粘贴操作）。

Answer 2

这肯定行得通
您只需在 onCreateActionMode() 中添加 mode.finish()

mEntryText.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) {

        /* This is done to solve the issue of SELECT ALL PASTE etc., showing up.
         mode.finish() should not be called at this point. If called, it will throw
         this exception "E/DecorView[]: Destroying unexpected ActionMode instance of TYPE_FLOATING;
         com.android.internal.view.FloatingActionMode@2e022bc was not the current floating action mode! Expected null"
         This makes that class not to execute the rest of the code and hence the FloatingAction is never created!
         I wish the the author of FloatingActionMode class gave me a method to just stop showing it. menu.clear()
         is supposed to do it, but doesn't do.
         */

            mode.finish();  // menu.close(); menu.clear();
            return false;
        }

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