EditText mEdit = new EditText(context);
InputType.TYPE_NUMBER_FLAG_DECIMAL、小数点型
InputType.TYPE_CLASS_NUMBER 整数型
设置Input的类型两种都要
mEdit.setInputType(InputType.TYPE_NUMBER_FLAG_DECIMAL|InputType.TYPE_CLASS_NUMBER);
设置字符过滤
mEdit.setFilters(new InputFilter[]{new InputFilter() {
@Override
public CharSequence filter(CharSequence source, int start, int end, Spanned dest, int dstart, int dend) {
if(source.equals(".") && dest.toString().length() == 0){
return "0.";
}
if(dest.toString().contains(".")){
int index = dest.toString().indexOf(".");
int mlength = dest.toString().substring(index).length();
if(mlength == 3){
return "";
}
}
return null;
}
}});
