We Keep Coding

I am unable to refer to things inside my activity, like buttons, and radiogroups

so I am trying to create an activity, and then add onclick listeners to it, but it wont let me refer. So the moment I open this activity in my app, my app crashes, saying 'void android.widget.Button.setOnClickListener(android.view.View$OnClickListener)' on a null object reference'
I have no idea why this is happening. I have correctly names them in accordance with the xml file as well.
Please help.

You didn't call in onCreate method setContentView(R.layout.youractivity). If you didn't, Android doesn't know what to render, so there are no views for you to provide.
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.youractivity);
}

just set your (xml)layout file to setContentView in onCreate()
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_layout);
}

How to save the data from multiple Edittexts that are being added dynamically in android?

I have some EditTexts and I'm trying to save their values to an ArrayList, but my EditTexts are being added by using an add button which adds a LinearLayout, and the EditTexts are within the LinearLayouts being created.
Normally having a fixed amount of EditTexts would be easy to save, but how would I save a continuous amount of EditTexts. I'm adding the LinearLayouts in the method createNewLinearLayout() below, and I want to save the input from the EditTexts from those LinearLayouts.
How can I do that?

I suggest :
for (int i =0;i<LinearLayout.getChildCount();i++)
{
EditText edt= new EditText (this);
edt = LinearLayout.getChildAt(i);
YourAarraylist[i]=edt.getText().toString();
}
If you have multiple views inside your LinearLayout you can repeat the for like this :
for (int i =0;i<LinearLayout.getChildCount();i++)
{
LinearLayout secondLayout= (LinearLayout) LinearLayout.getChildAt(i);
// and then:
EditText edt= new EditText (this);
edt = secondLayout.getChildAt(indexofyoutEdittext);//You should know this because it's the order of the views you add in your layout
YourAarraylist[i]=edt.getText().toString();
}
I hope it helps !

Showing text from string through TextView after pressing RadioButton

I'm trying to show automaticly "This is the correct answer" or "Try again" just right after the radio button is pressed.
My question is:
How to add two strings
<string name="Good_answer">That is the correct answer</string>
<string name="Wrong_answer">Try again</string>
to this textView
<TextView
android:id="#+id/textViewAnswer"
android:textAppearance="?android:attr/textAppearanceLarge"
android:textAlignment="center"
android:layout_below="#id/rg2"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
so I can proceed this
for (boolean radioAnswer : answer)
correct = correct && radioAnswer;
if (correct)
tv.setText(R.string.Good_answer);
else
tv.setText(R.string.Wrong_answer);
And here is setOnClick... (at first it was with checkbutton 'mbuton')
mbuton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
boolean check = true;
boolean correct = true;
// To check if all questions have been answered
for (boolean radioChecked : checked)
check = check && radioChecked;
if (check) {
// To check if all questions have been answered correctly
for (boolean radioAnswer : answer)
correct = correct && radioAnswer;
if (correct)
tv.setText(R.string.Good_answer);
else
tv.setText(R.string.Wrong_answer);
}
else
tv.setText("Answer all questions");
}
});

If your problem is just about setting those string in the TextView then, try this:
//For correct answer.
String CorrectAnswer = getString(R.string.Good_answer);
tv.setText(CorrectAnswer);
//For wrong answer.
String WrongAnswer = getString(R.string.Wrong_answer);
tv.setText(WrongAnswer);

The Code is still unclear (I can't Figure out what mButton is) .
However can you also share your layout xml I would suggest having a Radio Group comprising of X number of Radio Buttons (options) that you like and put the on checkedChangeListener
<RadioGroup
android:id="#+id/rgroup"
android:layout_width="fill_parent"
android:layout_height="45dp"
android:background="#drawable/background"
android:gravity="center"
android:orientation="horizontal" >
<RadioButton
android:id="#+id/option1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="5dp"
android:background="#drawable/test_image"
android:button="#null" />
<RadioButton
android:id="#+id/option2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="5dp"
android:background="#drawable/test_image"
android:button="#null" />
</RadioGroup>
Your Activity should implement the OnCheckedChangeListener and you can then define your Radio Group RadioGroup Options = (RadioGroup) findViewById(R.id.rgroup);
Then you can implement a method in your activity where if a option inside that Radio Button is clicked you can use the below method.
#Override
public void onCheckedChanged(RadioGroup group,
int checkedId)
{
switch (checkedId)
{
case R.id.option1:
// settextview to correct here
break;
case R.id.option2:
//set textview to wrong here
break;
default:
break;
}
}
Assuming you might have answers at dynamic positions you might want to code some logic in the on checked change method . Hope this helps

Layout file; look at those questions and answers. I've hardcoded the string here. You can set it in string resource file and fetch it here using #string or set it dynamically using yourTextView.setText() method.

I haven't use the string resources here, if you want to set the text view with the string from resources too, look it in my first answer.
So, I think this will help you.

Focus changes to listview once i clear the Edittext

I'm using broadcast receiver to show a dialog.So the flow of code is something like:
Step1 Getting the requestCode value
Step2 Based on this requestCode the broadCast receiver goes to if or else if or else part
Step3 If the value that i entered using some scanner into the EditText(i.e Scan) doesn't matches it shows a Toast "Item Not Available".
Step 4 Once "Item Not Available" toast comes the focus changes to the Listview which is my problem.
Step5 Again if i pass value to the Scan EditText the Listview get click automatically.
So my question is "How to remove focus from the Listview" and set it to the EditText(i.e Scan).
For Reference I'm attaching the snap with code snippet and the layout.xml.Please have a look and drop your suggestions why the focus is going to the listview.

Add a textwatcher to edit text and check when text is not blank and it is not equal to expected text then only switch the focus.
/* Set Text Watcher listener */
yourEditText.addTextChangedListener(passwordWatcher);
and check for text once user enter text
private final TextWatcher passwordWatcher = new TextWatcher() {
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
public void onTextChanged(CharSequence s, int start, int before, int count) {
}
public void afterTextChanged(Editable s) {
if (s.length() != 0 && passwordEditText.getText().equals("Your expected text")) {
// show your toast and change focus
}
}
}

You should make your listview not focusable by using setFocusable(false) when not required and when you get response correctly from barcode scanner then you can again make your listview focusable.
