if(checked) {score = score + 6;}

case R.id.question5_radioButton7:
if(checked) {score = score + 7;}
break;
}
}
To extend your app i would also recommend, that you generate the layout for questions dynamically in your source code, not as hardcoded layout xml.
Finally to display the result e.g. add a Button to the bottom and set the following code to display a dialog with the achieved score. As alternative you can also start a new Activity and show it there via Intent and Bundle.
private onClickedButtonResult(View v) {
AlertDialog alertDialog = new AlertDialog.Builder(this)
//set icon
.setIcon(android.R.drawable.ic_dialog_alert)
//set title
.setTitle("Your score")
//set message
.setMessage("You achieved a score of " + String.valueOf(score) + "!")
//set positive button
.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
//Call finish to close your app
finish();
}
})
.show();
}
Alternative:
Show score in another Activity
Create an Intent for the other Activity and save the value of score in the intent:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final Button generate_result_button = findViewById(R.id.jana_keputusan_button);
generate_result_button.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Intent generate_result_intent = new Intent(MainActivity.this, ResultActivity.class);
Bundle extras = generate_result_intent.getExtras();
extras.putExtra("SCORE", score);
startActivity(generate_result_intent);
}
});
}
And in your other Activity you can read the passed value of score and show it to the user:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_other);
Intent mIntent = getIntent();
if (i.hasExtra("SCORE")) {
int score = mIntent.getIntExtra("SCORE", 0);
// Do something to display the score
}
}
Finally, be aware that the user can increase his own score by clicking multiple times on a RadioButton. That should be addressed in your application logic, because the scoring would be invalid.

You can go to another activity and display result by INTENT. You can pass your score to another activity by using putExtra.
MainActivity:
okAction.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(MainActivity.this, AnotherActivity.class);
intent.putExtra("Score", score);
startActivity(intent);
}
});
Another Activity:
Intent intent = getIntent();
Bundle bundle = intent.getExtras();
if(bundle != null){
int score = bundle.getInt("Score");
restltText.setText("Your score is: "+ score);
}

To get text from RadioButton I offer you to use:
int indexOfButton = radioGroup.indexOfChild(findViewById(radioGroup.getCheckedRadioButtonId()));
String scoreS = (indexOfButton > -1)? ((RadioButton) radioGroup.getChildAt(indexOfButton)).getText().toString() : "";
score += Integer.parseInt(scoreS);
This methods is getting checked RadioButton id and by it finds index in that group. By the index you can get RadioButton text.
To show the score in other activity you can send data throw Intent extras. Like this:
Intent intent = new Intent(MainActivity.this, ResultActivity.class);
intent.putExtra("result", score);
startActivity(intent);
On ResultActivity.class you can get score from extras like this:
Integer result = 0;
Intent i = getIntent();
if (i.hasExtra("result")) {
result = i.getIntExtra("result");
}
Then you can display it in TextView or in other possible ways.
If you don't understand something, feel free to ask.
I hope it helps 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.

Outputting in different layout

I'm currently developing an mobile grocery app. I just want to ask you why my code in layout Y cant throw the details from different activity, but layout X can! As you can see, I used checkbox to checked all items you want to purchase, but in Layout Y, if u checked the item you want and click the "add to cart" button it crashed.
Tho I reedit the code based on respective information and copy to layout Y.
Here is my Code

When I clicked the link on Logcat it pointed me to
final_text.setText(final_shopping_selection); of layout Y

try to change it in Y
addtoFood = (Button) findViewById(R.id.addtocart);
final_text = (TextView)findViewById(R.id.final_shopping_food);
setContentView(R.layout.activity_baby__food);
to
setContentView(R.layout.activity_baby__food);
addtoFood = (Button) findViewById(R.id.addtocart);
final_text = (TextView)findViewById(R.id.final_shopping_food);
I think your text view is null in addtocart method.

The error is on one, two, three...nine and information count, human count etc. Here is my fragment file, so why can't I see one, two, three....nine labeled blue? Why is it not recognized? What have I done wrong ? I received the errors after findviewbyid.

When you got this type of error at anywhere and you have import android.R; then just remove import android.R;.

Enter data in EditText without default keyboard [closed]

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.
Closed 10 years ago.
How to enter data in my EditText using my own buttons instead of default keyboard (I mean like in calculator apps). Please write me some method or show suitable example. Thanks.
I initialize veriable, even tried to make some algorithm. But there is no reason to go further without knowing how to input data.
And of course I was looking for the answer.

You have to make your editText non focusable/editable and modify the text inside when you click on your buttons. Easy !
