I am writing a calculator for Android, for inputting expression I use EditText. As I create my buttons - I do not need a software keyboard, but I want to change the cursor position, text selection, copy, paste. In a word - everything as it is, only the virtual keyboard is not displayed. In version 2.3 I could write:

EditText.setInputType (InputType.TYPE_NULL);

and it worked perfectly. In version 4 of the cursor is not displayed, the menu does not work, etc. Tried a bunch of ways - you can not move the cursor, the keyboard is displayed, and it was never really explained. 

InputMethodManager imm = (InputMethodManager)getSystemService(
    Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(myEditText.getWindowToken(), 0); //cursor not showing
------------------------------------------------------------------------
getWindow().setSoftInputMode(
    WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN); //not working

I want to make it as in Panecal, MobiCalc Free, Scientific Calculator. I would be happy with any helpful suggestions on this. P.S. Sorry for my English.

From the link posted below, here is an example to consume on touch for an Edittext

editText_input_field.setOnTouchListener(otl);

private OnTouchListener otl = new OnTouchListener() {
    public boolean onTouch (View v, MotionEvent event) {
            return true; // the listener has consumed the event
    }
 };

Here is another example from the same website. This claims to work but seems like a bad idea since your EditBox is NULL it will be no longer an editor:

MyEditor.setOnTouchListener(new OnTouchListener(){ 
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        int inType = MyEditor.getInputType(); // backup the input type
        MyEditor.setInputType(InputType.TYPE_NULL); // disable soft input
        MyEditor.onTouchEvent(event); // call native handler
        MyEditor.setInputType(inType); // restore input type
        return true; // consume touch even
   }
});

Hope this points you in the right direction

The above answer was taken from - how to block virtual keyboard while clicking on edittext in android?

This might work too getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN);

textIsSelectable对此的确切解决方案是将EditText 中的标志设置为true。这将保留光标，您将能够使用基本的选择/复制/剪切/粘贴等功能。您可以在 xml 布局中设置它，如下所示：

您可以像这样以编程方式设置它：

EditText edit_text = (EditText) findViewById(R.id.editText);
edit_text.setTextIsSelectable(true);

或者在您的 XML 布局中：

<EditText
    ...
    android:textIsSelectable="true"
/>

对于使用 API 10 及以下版本的任何人，此处提供了 hack：https ://stackoverflow.com/a/20173020/7550472
