判断输入的内容是不是0-9的数字或者小数点

对EditText添加addTextChangedListener进行处理et.addTextChangedListener(new TextWatcher() { @Override public void onTextChanged(CharSequence s, int start, int before, int count) { // TODO Auto-generated method stub } @Override public void beforeTextChanged(CharSequence s, int start, int count, int after) { // TODO Auto-generated method stub } @Override public void afterTextChanged(Editable s) { // TODO Auto-generated method stub Log.i("TAG",et.getText().toString()); } });
