如何禁用Android EditText中的粘贴选项 [英] how to disable paste option in android EditText

问题描述

我有一个要求，其中EditText不允许粘贴，但应该允许复制. 我尝试了setCustomSelectionActionModeCallback，但是它禁用了复制选项.

I have an requirement where EditText doesn't allow paste but it should allow copy. I tried setCustomSelectionActionModeCallback but it disable copy option.

EditText  etxt = (EditText) findViewById(R.id.editText1);
etxt.setCustomSelectionActionModeCallback(new 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;
            }
        });

推荐答案

我完成了自己的工作..学分转到

I done my self..credit goes to Android intercept paste\copy\cut on editText

我只是根据自己的需要更改了onTextContextMenuItem().

I just changed onTextContextMenuItem() based on my requirement..

@Override
    public boolean onTextContextMenuItem(int id) {
        // Do your thing:
        //boolean consumed = super.onTextContextMenuItem(id); // Change1
        // React:
        switch (id){
            case android.R.id.cut:
                onTextCut();
                break;
            case android.R.id.paste:
                onTextPaste();
                return false;       //Change2
                //break;
            case android.R.id.copy:
                onTextCopy();
        }
        return true; // Change3
    }
