EditText设置字数限制并给出提示

好记性不如烂笔头

private final int MAX_NUM = 150;etInputAssess.setFilters(new InputFilter[]{new InputFilter.LengthFilter(MAX_NUM)});etInputAssess.addTextChangedListener(new TextWatcher() {            @Override            public void beforeTextChanged(CharSequence s, int start, int count, int after) {            }            @Override            public void onTextChanged(CharSequence s, int start, int before, int count) {                tvNumLimit.setText(s.length() + "/" + MAX_NUM);            }            @Override            public void afterTextChanged(Editable s) {            }        });

两个方法,1设置textview的最大字数,可以用代码也可以在xml中

 2 设置监听来给出当前提示
