Java – How do I add multi-select checkbox in warning dialog for Android?

I created the Sync menu in the Android app. When we click on the “Sync” alert, a 4 checkbox layout opens. What I want is for them to work, like I automatically unclick other options after 15 minutes of clicking.

@Override
public boolean onCreateOptionsMenu(Menu menu) 
{
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.action_menu, menu);
    return true;
}       
@Override
public boolean onOptionsItemSelected(MenuItem item)
{
    switch (item.getItemId())
    {
        case R.id.menu_settings:
            alertDialog = new AlertDialog.Builder(HomePage.this).create(); Read Update
            LayoutInflater adbInflater = this.getLayoutInflater();
            View checkboxLayout = adbInflater.inflate(R.layout.sync_layout, null);
            defaultchkbox = (CheckBox)checkboxLayout.findViewById(R.id.defaultchkbox);
            after15mint = (CheckBox)checkboxLayout.findViewById(R.id.after15mint);
            after30mint = (CheckBox)checkboxLayout.findViewById(R.id.after30mint);
            after45mint = (CheckBox)checkboxLayout.findViewById(R.id.after45mint);
            alertDialog.setView(checkboxLayout);
            alertDialog.setTitle("Synchronization");
            alertDialog.setMessage("Choose");

alertDialog.setButton(Dialog.BUTTON_POSITIVE,"Save changes", new DialogInterface.OnClickListener()
            {
                @Override
                public void onClick(DialogInterface dialog, int which)
                {
                     TODO Auto-generated method stub
                    boolean checkBoxResult = false; 
                        if(after15mint.isChecked())
                        {
                            Toast.makeText(getApplicationContext(), "15 Minute checked", Toast.LENGTH_LONG).show();
                            checkBoxResult = true;
                        }
                        else if(after30mint.isChecked())
                        {
                            Toast.makeText(getApplicationContext(), "30 Minute checked", Toast.LENGTH_LONG).show();
                            checkBoxResult = true;
                        }
                        else if(after45mint.isChecked())
                        {
                            Toast.makeText(getApplicationContext(), "45 Minute checked", Toast.LENGTH_LONG).show();
                            checkBoxResult = true;
                        }   
                        else{
                            Toast.makeText(getApplicationContext(),     "Default", Toast.LENGTH_LONG).show();
                        }
                }
            });
            alertDialog.setButton(Dialog.BUTTON_NEGATIVE, "Cancel", new DialogInterface.OnClickListener()
            {
                public void onClick(DialogInterface dialog, int which) 
                {
                    alertDialog.dismiss();
                }
            });
            alertDialog.show(); 
            return true;
default:
            return super.onOptionsItemSelected(item);
    }
}

But I’m a little confused about the work of checkboxes in alerts. Advice would help a lot. Thank you. 🙂

It looks like you need to use radio buttons nested in RadioGroup. Then it will only allow you to select one option at a time.

For more information about RadioGroup, see:
http://developer.android.com/reference/android/widget/RadioGroup.html

For more information about creating radio buttons, see:

http://developer.android.com/reference/android/widget/RadioButton.html

Especially for your code, you must define RadioButtons in the RadioGroup in R.layout.sync_layout, for example

<RadioGroup
    android:id="@+id/syncGroup"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" >

<RadioButton
        android:id="@+id/defualt"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text= "Default" 
        android:checked="true" />

<RadioButton
        android:id="@+id/minute15"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text= "15 Minute" />

<RadioButton
         android:id="@+id/minute30"
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         android:text= "30 Minute" />

<RadioButton
          android:id="@+id/minute45"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:text= "45 Minute" />

</RadioGroup>
