Am trying to do some simple calculations,I set a Listener on my fragment But it doesn't trigger the onClick method and the log shows nothing,According to an accepted answer here this should work,and most of alternatives didn't work for me,What is the cause of this behavior This is my fragment
public class AttendanceFragment extends Fragment implements View.OnClickListener {
EditText ET_days,ET_week;
TextView TV_attendance;
Button btn;
static int attendance;
public static final String TAG = "Checking";
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.attendance,container,false);
ET_days= (EditText) v.findViewById(R.id.et_days);
ET_week= (EditText)v.findViewById(R.id.et_week);
TV_attendance=(TextView) v.findViewById(R.id.tv_attendance);
btn=(Button)v.findViewById(R.id.btn_attendance);
btn.setOnClickListener(this);
return v;
}
@Override
public void onClick(View view) {
int days =Integer.parseInt(ET_days.getText().toString());
int week= Integer.parseInt(ET_week.getText().toString());
int d = days * 5;
int w = week * 75;
attendance= (d/w) * 100;
String att= String.valueOf(attendance);
Log.d("ATtendance",att);
TV_attendance.setText("Your Current Attendance is:"+att);
}
}
This my layout:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="10dp"
>
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/tv_days"
android:text="Enter The number of days you have missed so Far"
android:textSize="20sp"
android:layout_marginTop="20dp"
android:layout_gravity="center"
/>
<EditText
android:layout_width="200dp"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:hint="days missed"
android:id="@+id/et_days"
/>
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/tv_week"
android:text="Enter The Current school week Number "
android:textSize="20sp"
android:layout_marginTop="20dp"
/>
<EditText
android:layout_width="200dp"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:hint="week number"
android:id="@+id/et_week"
/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Your Current Attendance is: 85%"
android:layout_marginTop="40dp"
android:textSize="30sp"
android:id="@+id/tv_attendance"
/>
<Button
style="@style/Widget.AppCompat.Button.Borderless"
android:layout_width="250dp"
android:layout_height="60dp"
android:id="@+id/btn_attendance"
android:layout_marginTop="80dp"
android:layout_gravity="center"
android:text="Check Attendance"
android:textSize="18sp"
android:background="@drawable/button_selector"
android:textColor="@color/white"
/>
</LinearLayout>
EDIT:
the fragment is part of 5 fragents in BottomBar,these are in my MainActivity
public class MainActivity extends AppCompatActivity {
