封装的EditText的输入限制(输入的数字前+￥,精确到小数点后两位)

项目中用的EditText的输入金额的功能，在输入金额数字前面加￥符号，精确到小数点后两位，如果第一位输入的是小数点往前面自动补0，不能输入0000000X(X代表1-9)的限制

public static void setPricePoint(final EditText editText) {

editText.addTextChangedListener(new TextWatcher() {

@Override

public void onTextChanged(CharSequence s, int start, int before,

int count) {

if(s.toString().indexOf("￥")==-1){

System.out.println("input no ￥");

s = "￥"+s;

editText.setText(s);

editText.setSelection(s.length());

}

if(s.toString().length()>2){

if (s.toString().trim().substring(1,2).equals(".")) {

s = "￥"+"0" + s.toString().replace("￥", "");

editText.setText(s);

editText.setSelection(s.length());

}else if(s.toString().substring(1,2).equals("0")&&!s.toString().substring(2,3).equals(".")){

editText.setText(s.subSequence(0, 2));

editText.setSelection(2);

}

}

if (s.toString().contains(".")) {

if (s.length() - 1 - s.toString().indexOf(".") > 2) {

s = s.toString().subSequence(0,

s.toString().indexOf(".") + 3);

editText.setText(s);

editText.setSelection(s.length());

}

}

}

@Override

public void beforeTextChanged(CharSequence s, int start, int count,

int after) {

}

@Override

public void afterTextChanged(Editable s) {

// TODO Auto-generated method stub

}

});

}
