<EditText android:id="@+id/edit_text" android:maxLength="500" //maxLength其实对应java里的LengthFilter,解决方法与这个InputFilter无关。 android:layout_width="match_parent" android:layout_height="wrap_content"/> editText = findViewById(R.id.edit_text); editText.setFilters(new InputFilter[]{editText.getFilters()[0], mInputFilter}); //这里的editText.getFilters()[0]是为了保留上面的xml设置的LengthFilter同时有效
InputFilter mInputFilter = new InputFilter() { @Override public CharSequence filter(CharSequence source, int start, int end, Spanned dest, int dstart, int dend) { return source.toString().replace("\n", ""); }};
