早安，伙计们。这又是我，大卫·迪马兰塔。我是来问问题的。我需要创建一个程序，如果所有三个玩家的名字都不同，确认将在 toast 上显示“过程完成”。但相反，甚至所有人都没有相同的名字。
脚步：
- 每个玩家从旋转器中选择一个名字。
- 该值被写入字符串。
- 单击按钮时，该过程会评估相似性别名（名称）。
- 如果相似，至少有两个，toast 消息将显示“请指定不同的用户名”。
- 如果没有，那么它就完成了。
而且，我的活动名称是“Player_3_at_Spinner_Menu.java”。这是我在这个类的第一部分的代码：
//Spinners for Players
private Spinner spinner_1;
private Spinner spinner_2;
private Spinner spinner_3;
//Button to Start
private Button play_it;
//For Displaying Text
private String SUMMON_PICK_UP_1, SUMMON_PICK_UP_2, SUMMON_PICK_UP_3;
private String cplayer_1, cplayer_2, cplayer_3;
//Text Response from a Spinner
public final static String EXTRA_MESSAGE_1 = "com.example.databasetestvertwo.MESSAGE1";
public final static String EXTRA_MESSAGE_2 = "com.example.databasetestvertwo.MESSAGE2";
public final static String EXTRA_MESSAGE_3 = "com.example.databasetestvertwo.MESSAGE3";
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.players_3);
//Searching for ID... (Button)
play_it = (Button) findViewById(R.id.START_GAME);
//Adding listener to the button(s).
play_it.setOnClickListener(new trigger_happy_start());
//Call from the Database_Handler.class to call the database.
Database_Handler db = new Database_Handler(getApplicationContext());
//Then, load the content and...
loadSpinnerData();
}
//Insert the value from the database into each of the spinners.
private void loadSpinnerData()
{
//Initialize the spinners.
spinner_1 = (Spinner) findViewById(R.id.player_1_spinner);
spinner_2 = (Spinner) findViewById(R.id.player_2_spinner);
spinner_3 = (Spinner) findViewById(R.id.player_3_spinner);
Database_Handler db = new Database_Handler(getApplicationContext());
List<String> lables = db.getAllLabels();
//Creating an adapter for the spinner...
ArrayAdapter<String> data_adapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, lables);
data_adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
//Inserts the spinners by a database.
spinner_1.setAdapter(data_adapter);
spinner_2.setAdapter(data_adapter);
spinner_3.setAdapter(data_adapter);
}
//Action applied if a user chose this item. (Player 1)
public class response_1 implements OnItemSelectedListener
{
public void onItemSelected(AdapterView<?> parent, View view, int position, long id)
{
SUMMON_PICK_UP_1 = parent.getItemAtPosition(position).toString();
Toast.makeText(parent.getContext(), "You selected: " + SUMMON_PICK_UP_1, Toast.LENGTH_SHORT).show();
}
public void onNothingSelected(AdapterView<?> arg0)
{
//Do nothing. I guess...
}
}
//Action applied if a user chose this item. (Player 2)
public class response_2 implements OnItemSelectedListener
{
public void onItemSelected(AdapterView<?> parent_2, View view, int position, long id)
{
SUMMON_PICK_UP_2 = parent_2.getItemAtPosition(position).toString();
Toast.makeText(parent_2.getContext(), "You selected: " + SUMMON_PICK_UP_2, Toast.LENGTH_SHORT).show();
}
public void onNothingSelected(AdapterView<?> arg0)
{
// TODO Auto-generated method stub
}
}
//Action applied if a user chose this item. (Player 3)
public class response_3 implements OnItemSelectedListener
{
public void onItemSelected(AdapterView<?> parent_3, View view, int position, long id)
{
SUMMON_PICK_UP_3 = parent_3.getItemAtPosition(position).toString();
Toast.makeText(parent_3.getContext(), "You selected: " + SUMMON_PICK_UP_2, Toast.LENGTH_SHORT).show();
}
public void onNothingSelected(AdapterView<?> arg0)
{
// TODO Auto-generated method stub
}
}
而且，这是检查所有或至少两个玩家是否有相同名字的代码，该过程警告他们不要在此活动下使用相同的名字。这是我的代码：
private class trigger_happy_start implements OnClickListener
{
public void onClick(View v)
{
//Checks if the names assigned on each spinner have a the same name.
if
(
SUMMON_PICK_UP_1 == SUMMON_PICK_UP_2 ||
SUMMON_PICK_UP_1 == SUMMON_PICK_UP_3 ||
SUMMON_PICK_UP_2 == SUMMON_PICK_UP_3
)
{
Toast.makeText(getApplicationContext(), "Please specify a different username.", Toast.LENGTH_SHORT).show();
}
else
{
Toast.makeText(getApplicationContext(), "Process complete, idiot.", Toast.LENGTH_SHORT).show();
}
}
}
