필터 기능을 만들려고합니다. 검색 활동에 팝업 창이있어서 사용자가 스위치를 켜고 끌 수있는 스위치 목록을 표시합니다. 나는 팝업 표시 괜찮아요하지만 언제든지 스위치를 틱 때마다 가치가 검색 활동에 전달되고 아무것도 안하고있다. 여기 내 코드입니다 : 나는 "토스트"를 사용하고팝업 내부 스위치 사용
filter.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
initiatePopupWindow();
}
});
팝업 기능 (SearchActivity 내부)
private void initiatePopupWindow() {
try {
// We need to get the instance of the LayoutInflater
LayoutInflater inflater = (LayoutInflater)SearchActivity.this
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.activity_filter,
(ViewGroup) findViewById(R.id.popup_element));
pwindo = new PopupWindow(layout ,ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.WRAP_CONTENT,true);
pwindo.showAtLocation(layout, Gravity.CENTER, 0, 0);
switch1 = (Switch) findViewById(R.id.parking);
switch2 = (Switch) findViewById(R.id.delivery);
switch3 = (Switch) findViewById(R.id.reservation);
switch4 = (Switch) findViewById(R.id.bar);
switch5 = (Switch) findViewById(R.id.card);
switch6 = (Switch) findViewById(R.id.wifi);
switch7 = (Switch) findViewById(R.id.terrace);
btnClosePopup = (Button) layout.findViewById(R.id.btn_close_popup);
btnClosePopup.setOnClickListener(cancel_button_click_listener);
switch1.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton compoundButton, boolean bChecked) {
if (bChecked) {
parking_filter=1;
Toast.makeText(getApplicationContext(),
"Searching Database using : " + parking_filter,
Toast.LENGTH_SHORT).show();
} else {
parking_filter=0;
Toast.makeText(getApplicationContext(),
"Searching Database using : " + parking_filter,
Toast.LENGTH_SHORT).show();
}
}
});
