如何给EditText定焦点隐藏软盘限制字符个数

//定焦点定焦点到字符串最后面CharSequence query = et_loc_qhis_query.getText();if (query instanceof Spannable) {    Spannable spanText = (Spannable)query;    Selection.setSelection(spanText, query.length());}//搜索时隐藏键盘InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);imm.hideSoftInputFromWindow(et_loc_qhis_query.getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);//限制字符个数android:maxLength="16"或editText.setFilters(new InputFilter[]{new InputFilter.LengthFilter(10)});
