我已经在Android应用程序中创建了“同步”菜单.当我们单击“同步”警报时,打开4个复选框的布局.我想要的是让它们起作用,例如,当我单击15分钟,然后自动取消单击其他选项时.

@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);

}

}

但是我对警报中复选框的工作有些困惑.建议将有很大帮助.谢谢. ?
