Disabling RadioGroup to avoid multiple counts of a score

I am trying to disable my RadioGroup so that the user cannot re-select and therefore my score count rises. I have seen an implementation here:
How to disable a RadioGroup until checkbox is checked
Albeit tried to go about it this way
My xml:
<RadioGroup
android:id="#+id/rg1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="#dimen/sm_margin"

<RadioButton

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="#dimen/sm_margin"

</RadioGroup>
Java:
int score = 0;
RadioGroup rgQ1;
RadioGroup rgQ2;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
rgQ1 = findViewById(R.id.rg1);
rgQ2 = findViewById(R.id.rg2);
}
public void onRadioButtonClicked(View view) {
// Is the button now checked? then assign into a boolean named 'checked'
boolean checked = ((RadioButton) view).isChecked();
// Question 1 logic
// Check correct answer is checked and update score
switch (view.getId()) {
case R.id.frites:
if (checked) score += 1;
Log.v("MainActivity", "score" + score);
break;
}
// Disable RadioButtons of rg1
for (int i = 0; i < rgQ1.getChildCount(); i++) {
(rgQ1.getChildAt(i)).setEnabled(false);
}
// Question 2 logic
// Check correct answer is checked and update score
switch (view.getId()) {
case R.id.mille_feuille:
if (checked) score += 1;
Log.v("MainActivity", "score" + score);
break;
}
// Disable RadioButtons of rg2
for (int i = 0; i < rgQ2.getChildCount(); i++) {
(rgQ2.getChildAt(i)).setEnabled(false);
}
}
}
It disables the first radiogroup when an item is selected and also the 2nd (before a user has selected for the 2nd radiogroup.
Any ideas?

You are disabling your second radio group in the same click event. Check which radio button group is selected.
Like this, Similarly check group two and disable radio button group two!
int selectedId = radioGroup.getCheckedRadioButtonId();
if(selectedId != null){
//Then disable radio button group one
}

Android - How do I keep a button clicked (Selected)?

I am trying to build a calculator with two TextView fields for the two numbers. I figured out how to input the numbers using an "in-app" number pad for the top number, Operand 1 [textView] (I know it would be easier using an EditText but this is for an assignment). I am having trouble switching to the second textView, Operand 2 [textView2].
When I am done input the number for textView, I want to switch to textView2 (using the plus, minus, mult, and/or div Buttons) and continue to enter in the numbers so I can use it for calculations.
Here is an Image of what my app looks like. Please ignore the stars, progress bar, and raido buttons as they are apart of the assignment but not relevent to the calculator.
Do you have any suggestion about how I can do this?

You have to listen the key clicks after the plus/minus/.. button clicks occurs. Use a flag. set the flag 1 when plus/minus/.. or textview2 gets clicked and change the textview to textview2 and list1 to list2. Do the vice versa when textview1 is clicked.

you can do something like this :
public class YourActivityName extends AppCompatActivity {
TextView operand1, operand2,result,tv;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.dd);
operand1 = (TextView) findViewById(R.id.textView);
operand2 = (TextView) findViewById(R.id.textView2);
result= (TextView) findViewById(R.id.textView3);
tv=operand1;
}
public void sendMessage(View v) {
if (v.getId() == R.id.button19 || v.getId() == R.id.button15 || v.getId() == R.id.button17 || v.getId() == R.id.button21 || v.getId() == R.id.button18) {
tv=operand2;
}
if(v.getId()==R.id.button7){
tv.setText(tv.getText()+"7");
}
if(v.getId()==R.id.button8){
tv.setText(tv.getText()+"8");
}
if(v.getId()==R.id.button23){
int op1=Integer.parseInt(operand1.getText().toString());
int op2=Integer.parseInt(operand2.getText().toString());
op2+=op1;
result.setText(op2+"");
tv=operand1;
operand1.setText("");
operand2.setText("");
}
}
}
this is code only for having addition on pressing '=' button and for taking input only from button '7' and '8' you need to and functionality for other buttons and operations ..but it should solve your problem of changing textview for input...
you can also do by means of flags . as suggested by #Code-Apprentice ...

You should toggle a boolean flag whenever the user clicks an operator button. Then when the user clicks a number button, check this flag to determine which operand is being used.
In conjunction with this flag, you can also have a variable like TextView currentTextView which is assigned to refer to the currently used TextView. Then whenever the user clicks an operator button, assign this variable to the other TextView. This strategy will make it so you only need if statements in the OnClickListeners for the operator buttons. You won't need any if statements in the OnClickListeners for the number buttons.
p.s. Note that every number button already displays the numerical character. You can use this fact to remove nearly all of the if...else chain in your click listener.
p.p.s. You should consider writing different OnClickListeners for each button. With the previously mentioned strategy, you can have a single listener for all the number buttons, but I still suggest creating a different listener for each operator button.

The Error is on Apple=(ImageView)findViewById(R.id.Apple);
but somehow I noticed the difference before the Problem and After the Problem. Before the problem, when I modify th R.java it says error so I have to restore. But After the problem when I modify R.java it says no Error, I was able to save the change. Does my R.java not generate? I do the reserach but I cant fix the problem. Everybody said the manifest, but I dont know what to change. What happned? How to fix this?

Android - Errors when trying to change activities

For some reason this came up when trying to switch activities. I've had no problem running the same kind of code with other activities in this project. I'll post the code and see if anyone can figure it out ;(
I can't get my error to format right in this, so here's the error log
http://textuploader.com/oe6g
Here's my different activities.
The Problem occurs when I click on the button in my New Game Activity Layout, and that button runs the confirm(View view)

I mean it tells me the error occurs in the onCreate of the CourtActivity, however I can't see anything that's wrong. This is part of my school project, I'm only concerned with the things that are causing me errors currently, not too worried about anything else.
Note:This is a group project. The courtactivity screen is the only one I've not had a part in making, so I'm not sure exactly what went into it. However now I'm trying to put everything together and running into this.
Anything helps! Thanks!

The error is happening while attempting to load an image specified on the Layout file, as reported by the following part of the log:
...: Caused by: java.lang.OutOfMemoryError
...: E/AndroidRuntime(2137): at android.graphics.BitmapFactory.nativeDecodeAsset(Native Method)
...: E/AndroidRuntime(2137): at android.graphics.BitmapFactory.decodeStream(BitmapFactory.java:503)
I bet if you remove the line android:background="#drawable/bg2court" from the root container (RelativeLayout) in the file activity_court.xml the error will be gone.
If that is the case I would suggest you to try a smaller (lower resolution) version of that image.
While looking for a replacement, keep an eye on the heap memory allocation messages on logcat so you will know how much progress you are making.
Loading high resolution images on Android is usually a tricky process because of the following reasons:
Bitmap files loaded in memory have to be decompressed so they can be rendered, making them a lot larger then their original .JPG and .PNG files. To calculate how many bytes of memory will be allocated to load a given image, just follow this simple formula: width (pixels) x height (pixels) x number bytes per pixel (3 for 24 bit images). Example: a bitmap with the size of 2048x2048 pixels takes exactly 12mb of memory;
Bitmaps are loaded into the heap space which happens to be a pretty small portion of memory given by the OS to your app when it starts. The size of the heap space usually ranges from 16 to 64mb depending on the device.
Finally, I would suggest one of the following approaches:
Replace the large background image by a lower resolution version that can be scaled up to fill the background space (at the cost of quality of corse);
Load bitmaps programmatically. There are BitmapFactory methods that can downsample images on the fly, during the load process. More on this here;
Use a 3rd party library to do it for you. Picasso is an excelent choice.

The error is coming from inflating the layout. It's an OutOfMemoryError. Do you have some really huge bitmap or more likely a circular dependency? Can you upload the xml file R.layout.activity_court?

I had this error no long ago but got some help from the guys in here
here is what I did
if your background / image don't need transpart stuff or like keep in JPG format as it will be smaller. this should sort your Out of Memory issue temp. but when you have more image coming up you will still have problem (Out of Memory) coming up again
hope this can help you for the time been

Calculator error in java (classes)

I'm trying to make a simple calculator app for android and i'm stuck now. I was planning to make 2 calculators (one basic and the other more advanced, similar to the one built in Windows). The idea was to make it in 3 different classes.
Two classes would contain the "main" code (buttons, layout) and the last one should contain the function which im planning to call (like add, multiply). I managed to finish both calculators in one class but i don't know how to make them call functions from the other class.
PROBLEM: I managed to create the basic calculator and it can call functions from the other class but if i want to add more calculations one after another it wont work right. What I mean is this: Let's say my first number is 1 and my second is 3. It prints the result 4 but if i click add again and put 2 it prints the result 5 instead of 6. Somehow it stores the second variable into the first one and i cannot figure out why :(
Can anyone help me?
Thanks in advance

You are putting the result of the operation into the global var 'num1'.
The next time you press '+' you overwrite that value with the previous saveNumber value.
So your logic is like this:
1 -> savenumber = 1
+ -> num1 = 1
3 -> savenumber = 3
= -> num2 = savenumber
-> res = num1 + num2
-> num1 = res
+ -> num1 = savenumber = 3
2 -> savenumber = 2
= -> num2 = savenumber
-> res = num1 + num2
= 3 + 2
