Вот в этом коде, когда я даю текущее местоположение нормально и назначение из автозаполнения TextView расстояния автоматически появился в текстовом ..Как очистить текст в другом текстовом виде, когда я ввел текст в автоматический полный текст и очистил его в Android?
Так что, когда я очистить текст в автозаполнении TextView, автоматически уже появился расстояние должно быть очищено ? Может у объяснить?
Спасибо и его работы ... Я использовал this..as Что у Said..public пустота afterTextChanged (редактируемые s) { \t \t \t \t если (s.length() == 0) { \t \t \t \t \t distance_calc.setText («Показать расстояние»); \t \t \t \t} \t \t \t} –
