问题 I want to know by using which method I can get whether the user selecting text in edittext or not so I can use getSelectionStart and getSelectionEnd to perform my desire task. 回答1: You can check if your EditText widget has been focused (usually when user touches it on the screen). findViewById(R.id.editText1).setOnFocusChangeListener(this); and then implement the listener (in this case within the same class) public void onFocusChange(View arg0, boolean arg1) { switch(arg0.getId()){ case R.id
