有关EditText不满足条件给出提示自动清空数据

前提：需要在布局文件中声明：android:inputType="number"

myEdit.addTextChangedListener(new TextWatcher(){

int l=0;//字符串被删除字符之前，字符串的长度

int location=0;//光标的位置

@Override

public void beforeTextChanged(CharSequence s, int start, int count, int after) {

l=s.length();

location=edit.getSelectionStart();

}

@Override

public void onTextChanged(CharSequence s, int start, int before, int count) {

Pattern p = Pattern.compile("^(100|[1-9]\\d|\\d)$");

Matcher m =p.matcher(s.toString());

if(m.find() || ("").equals(s.toString())){

}

else{

Toast.makeText(context, "重新输入亲", Toast.LENGTH_SHORT).show();

}

}

@Override

public void afterTextChanged(Editable s) {

}});
