As per Java docs
The Identifier in a EnumConstant may be used in a name to refer to the enum constant.
so we need to use the name only in case of an enum.
Change to this
switch (Prefs.getCardStyle()) {
case COMPACT: rCompact.setChecked(true); break;
case FLAT: rFlat.setChecked(true); break;
case MATERIAL: default: rMaterial.setChecked(true); break;

Check if a property of a custom object ArrayList is an empty string or not?

I want to hide a WebView object (txtCode) if the code property of a custom object Arraylist (arrQues) contains nothing.
if (arrQues.get(count).code.isEmpty())
txtCode.setVisibility(View.GONE);
Its an ArrayList of custom objects fetched from a database table which is shown below
And if the code property does contains code then I have dynamically added rules to layout as shown below:
if (!(arrQues.get(count).code.isEmpty())) {
submit_params.removeRule(RelativeLayout.BELOW);
submit_params.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
submit_params.bottomMargin = (int) convertPxToDp(getContext(), convertDpToPx(getContext(), 15));
main_params.addRule(RelativeLayout.ABOVE, submitContainer.getId());
mainContainer.setLayoutParams(main_params);
submitContainer.setLayoutParams(submit_params);
}
The issue is when I load the second question and so on... the layout gets messed up and the current question number does not shows as 2 even if its 2 as shown in below:
Both of these issues only arises whenever I use...
arrQues.get(count).code.isEmpty() in the code
I have also tried using "" instead of isEmpty() and even null, but the result was same.
Also what I have noticed is only those questions are loaded from database which have something in the code column.
Below is the complete code for Java file

}
public float convertPxToDp(Context context, float px) {

}

I solved it, all issues were happening because arrQues.get(count).code was fetching null values from the database(The column "Code" had null values). As soon as I replaced null values with empty strings "" isEmpty() worked perfectly. I guess isEmpty() doesn't work with null values and is only intended for empty strings.

You are missing break; at the end of the switch branches.

Fall Through.
You have to add the break.
case 0:
mColor.setText("#000000");
break;
You can find that in docs
The break statements are necessary because without them, statements in switch blocks fall through: All statements after the matching case label are executed in sequence, regardless of the expression of subsequent case labels, until a break statement is encountered.

You need a break when you don't have a return otherwise it causes fall through

You need the break; after all cases except for the last one or else it'll fall through case by case
switch (which){
case 0:
mColor.setText("#000000");
break;
case 1:
mColor.setText("#0000FF");
break;
case 2:
mColor.setText("#0R00FF");
break;
case 3:
mColor.setText("#0R00dsdFF");
break;
case 4:
mColor.setText("#0R0dfdf0FF");
default:
break;

AlertDialog.Builder adb = new AlertDialog.Builder(CategoriesTab.this);
adb.setTitle("Selected Category");
adb.setMessage("Selected Item is = "+lv1.getItemAtPosition(position));
adb.setPositiveButton("Ok", null);
adb.show();
}
This at the moment displays an alertbox when an item from listview is clicked. I want to convert the alertbox to load a specific xml for each choices clicked. How can i do this?
thanks for your help.

switch(position) {
case 0:
setContentView(R.layout.xml0);
break;
case 1:
setContentView(R.layout.xml1);
break;
default:
setContentView(R.layout.default);
break;
}
i hope this will do the job!

#Override
public void onClick(View v)
{
switch (v.getId())
{
case R.id.:
break;
case R.id.:
break;
default:
break;
}
}

switch(position) {
case 0:
...
break;
case 1:
...
break;
default:
...
}
Did you mean that?

You can do this:
#Override
protected Dialog onCreateDialog(int id) {
String messageDialog;
String valueOK;
String valueCancel;
String titleDialog;
switch (id) {
case id:
titleDialog = itemTitle;
messageDialog = itemDescription
valueOK = "OK";
return new AlertDialog.Builder(HomeView.this).setTitle(titleDialog).setPositiveButton(valueOK, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
Log.d(this.getClass().getName(), "AlertItem");
}
}).setMessage(messageDialog).create();
and then call to
showDialog(numbreOfItem);
