How to clear the selection in an EditText?

问题

How do you programmatically remove the selection from an EditText? I've tried:

myEditText.setSelection(selectionEnd);

but that just creates a selection of 0 length at the end of the current selection. I've also tried Selection.removeSelection(mySpannable), and it just puts an empty selection at the beginning of the text.

回答1:

Calling myEditText.clearFocus();. I think that's what you need

回答2:

To move selection to top:

edit_text.setSelection(0);

To move selection to bottom:

edit_text.setSelection(edit_text.getText().length());

回答3:

EditText message = (EditText) findViewById(R.id.sendText);
String text = message.getText().toString();
message.setText(null);
