7 Buttons, 3 AsyncTasks, 1 Activity, and a nightmare [closed] - java

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center.

Just when I thought I had this one cinched, I realized that I can only use the buttons in the activity in the same sequence they are written in the Activity.java (Ex: Cannot execute button 5 press, until 1,2,3,and 4 have all been pressed!)
How do I fix this?

Menu does not show either! All help appreciated!

You need to override the method onCreateOptionsMenu. I give you the sample code:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
menu.add(group1Id,searchBtnId ,searchBtnId,"Search");
menu.add(group2Id,scheduleBtnId ,scheduleBtnId,R.string.schedule);
menu.add(group2Id,playBtnId ,playBtnId,"Play");
menu.add(group2Id,stopBtnId ,stopBtnId,R.string.stop);
return super.onCreateOptionsMenu(menu);
}

Why not create one Async class that can do 4 different types of downloads? This class would take as parameters: the button, the textview, and the url. Then you have 1/4 as much code. In the async, make all the buttons non clickable (setClickable(false)).
At any rate, you need to assign an onclicklistener for all the buttons at OnCreate(). You could make a custom class and switch on the button type, or just do the individualized anonymous class route.

Combine use of OnClickListener and OnLong Click Listener

Actually I created a pdf viewer and i jus want to create a longclicklistener to open my new activity and as u can see here
Screenshot
And there is already a click listener assigned with this button and i also want to combine longclicklistener so when i long click that button then automatically launch my second activity

android.widget.ProgressBar cannot be cast to android.widget.RelativeLayout

I'm new to android studio. Currently I'm working on a medlabtut app on android for over 3 months now. I'm having an issue on the login button on the MedLabStartUpScreen that actually supposed to launch the login screen when clicked on. Rather it crashes the app completely and shows a runtimeException at my //Connection Hooks "progressbar = findViewById(R.id.login_progress_bar);" of my login.java class file, that android.widget.ProgressBar cannot be cast to android.widget.RelativeLayout.

}
}

On around line 7 you declare this variable:
RelativeLayout progressbar;
You then correctly go on to initialise this variable with:
progressbar = findViewById(R.id.login_progress_bar);
The issue is that in the xml, the view (widget) with this ID is a ProgressBar, but the type declaration for progressbar in the Java code is RelativeLayout. Your code is therefore trying to cast the ProgressBar in the layout file into a RelativeLayout, which can't be done.
You can fix this by changing the declaration on line 7 to:
ProgressBar progressbar;
(And then adding the necessary import at the top of your Java file: import android.widget.ProgressBar;).
Hope this helped.

Instead of passing the data to the Profile activity use the GoogleSignIn.getLastSignedInAccount(getActivity()); method to get user profile data.
Replace your,
Intent i = getIntent();
final String i_name, i_email, i_url;
i_name = i.getStringExtra("p_name");
i_email = i.getStringExtra("p_email");
i_url = i.getStringExtra("p_url");
with the following code,
GoogleSignInAccount acct = GoogleSignIn.getLastSignedInAccount(getActivity());
if (acct != null) {
String i_name = acct.getDisplayName();
String i_email = acct.getEmail();
Uri i_url = acct.getPhotoUrl();
}

How would I get the new selected value of the radio group and save it to the database?

You should be able to do something like this:
int radioButtonId = mSport.getCheckedRadioButtonId();
View radioButton = mSport.findViewById(radioButtonId);
int idx = mSport.indexOfChild(radioButton);
To get selected RadioButton Text in a RadioGroup, please use the following code:
RadioButton rb = (RadioButton) mSport.getChildAt(idx);
String selectedText = rb.getText().toString();
But note, this code will work only if the radio buttons are direct children of your RadioGroup. So you need to remove those "LinearLayouts". In fact, there is no need to use those layouts at all. You can set the orientation of your RadioGroup to "vertical", in your .XML file, using the following line of code:
android:orientation="vertical"

Optimizing layout/bitmaps/database with ASYNC or another thread?

As a beginner I have some questions about optimizing my application speed. I'm building a simple quiz app there I have an sqlite database inside with some information. With that information I'm generating my questions in quiz page.
It was working pretty fine and fast until I fixed some buttons/background in sketch and use them. Now it's working much more slower and I'm getting error messages at logcat like "Skipped xxx frames! The application may be doing too much work on its main thread." I have searched on google for a while and found out that the bitmaps are slowing down my application. Have read about async and using a new thread to make it run faster.
As a solution I have resized some of my bitmaps, but then I'm getting less quality in my design, so I decided to fix it. I have googled some more about loading my layout with async or a new thread but didn't really find out how/where to do it. What makes me confused is that I don't know if it's to load layout with a new thread is the best solution or to load other processes with new thread. Need some recommendation about how to optimize my app. Here is my code, at least the quiz page that is slowest. I'm not really sure what to optimize there with a new thread. Under a question it's just countdowntimer that is running, and when next clicked countdowntimer starts over and the gui updates with the new question.
My quizpage code:

I don't think it has much to do with bitmaps, especially if you are pulling them from Drawable resources. The source of your lag is likely your database queries, which are happening in onCreate, which are blocking the main thread to do disk access. Instead, use a CursorLoader as described in https://developer.android.com/training/load-data-background/setup-loader.html
