我已經在Android應用程序中創建了“同步”菜單.當我們單擊“同步”警報時,打開4個復選框的布局.我想要的是讓它們起作用,例如,當我單擊15分鐘,然后自動取消單擊其他選項時.

@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);

}

}

但是我對警報中復選框的工作有些困惑.建議將有很大幫助.謝謝. ?
