早上好伙计。 David Dimalanta,这是我。我在这里提出一个问题。我需要创建一个程序,如果所有三个玩家都有不同的名字,那么确认将在“完成过程”上说。但相反,即使所有人都没有相同的名字。下面的行 - 使三个纺纱厂和玩家添加或选择不使用相同的名称
步骤:
- 每个玩家从旋转选择的名称。
- 将值写入字符串。
- 点击按钮后,该过程将评估相似度别名(名称)。
- 如果相似,至少两个,吐司消息将会说“请指定一个不同的用户名”。
- 如果不是,那就完成了。
而且,我的活动名称是“Player_3_at_Spinner_Menu.java”。这是我对这个类下的第一部分代码:
//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,这里的检查,如果所有的代码,或至少两个,球员得到了相同的名称,过程警告他们不要使用相同的名称下这个活动也。这里是我的代码:
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();
}
}
}
哦!我明白了,ariefbayu。并且,感谢您的帮助。我几乎感到困惑,因为我专注于** private类trigger_happy_start **下的** onClick()**方法。我从来没有意识到我忘了为每个微调者设置听众。再次感谢您的帮助。 – 2012-07-31 03:48:30
