There is a small Problem in the app that i developed ( BMI Calculator ). Everything works well the app works well and good when user is entering the details or any pop up message and toast are well defined and works well. the main problem arise when the bottom sheet which consist of results POP-UP and nothing shows up there its just the default text view hints showing and i dont know what's the problem behind this please help me out to solve the Problem.
PLEASE NOT THAT I AM NOT GIVING ENTIRE CODE I AM JUST PROVISING THE NESSARY CODE IGNORE ANY SYNTAX ERRORS
**THIS IS THE base bmi.java FILE**
package com.suryakalyan;
public class Bmi extends AppCompatActivity {
private double bmi;
double weight;
EditText edtgender, edtage, edtheight, edtweight, edtheightFeet, edtheightInches;
TextView txtbmi_category, txtbmi_score, txtbmi_suggestion, edtdecimal;
Button btnsubmit, recalculate;
@Override
protected void onCreate( Bundle savedInstanceState ) {
super.onCreate( savedInstanceState );
setContentView( R.layout.layout );
edtgender = findViewById( R.id.gender );
edtheightFeet = findViewById( R.id.height_feet );
edtheightInches = findViewById( R.id.height_inches );
edtage = findViewById( R.id.age );
edtheight = findViewById( R.id.height );
edtweight = findViewById( R.id.weight );
edtdecimal = findViewById( R.id.decimal );
btnsubmit = findViewById( R.id.submit );
unitHeightSpinner = findViewById( R.id.unit_height_spinner );
unitWeightSpinner = findViewById( R.id.unit_weight_spinner );
View bottomSheetView = getLayoutInflater().inflate( R.layout.fragment_bottom_sheet_results, null );
txtbmi_score = bottomSheetView.findViewById( R.id.bmi_score );
txtbmi_category = bottomSheetView.findViewById( R.id.bmi_category );
txtbmi_suggestion = bottomSheetView.findViewById( R.id.bmi_subcategory_suggestion );
recalculate = bottomSheetView.findViewById( R.id.recalculate );
edtgender.setOnClickListener( new View.OnClickListener() {
@Override
public void onClick( View v ) {
PopupMenu popupMenu = new PopupMenu( Bmi.this, edtgender );
popupMenu.getMenuInflater().inflate( R.menu.menu, popupMenu.getMenu() );
popupMenu.setOnMenuItemClickListener( new PopupMenu.OnMenuItemClickListener() {
@Override
public boolean onMenuItemClick( MenuItem item ) {
// Handle the selected gender option here
String selectedGender = item.getTitle().toString();
edtgender.setText( selectedGender );
return true;
}
} );
popupMenu.show();
}
} );
`And ALL THE REMAINING CONSIDITON AND ETC FOR BMI CALCULATION IS DONE WITHOUT ERRORS AND THE BMI IS SET USING SETTEXT`
if (bmi < 15) {
txtbmi_category.setText( "Better Luck Next Time!" );
txtbmi_suggestion.setText( "Better luck next time!" );
} else if (bmi >= 15 && bmi < 17) {
txtbmi_category.setText( "Severely underweight" );
txtbmi_suggestion.setText( "Don't worry, you're just a few pounds away from being super skinny!" );...............remaining conditions
