應用程序第一次運行時如何禁用單擊按鈕

Question

在我的應用程序中，我有2個按鈕。
開始遊戲中的第一個按鈕和繼續遊戲中的第二個按鈕。
我想在應用程序運行時第一次禁用第二個按鈕。
這意味着第一次我的第二個按鈕被禁用到onClick。如何處理這個？
我怎樣才能讓它明白這是第一次？

public class Menu extends Activity implements View.OnClickListener { 

SharedPreferences prefs; 
Editor edit; 
TextView best; 
private boolean flag; 
public static ImageView btn1, conti, but3, but4;

    flag = PreferenceManager.getDefaultSharedPreferences(this).getBoolean("flag", false); 


    if (applist == null) { 
     applist = new AppList(this); 
     applist.set_identity("1"); 
    } 

    if (splash == null) { 
     splash = new Splash(this);

    but4.setLayoutParams(params); 
    but3.setLayoutParams(params); 
    btn1.setLayoutParams(params);

}

      break; 
     case R.id.button4: 
      applist.Display(); 
      break; 
    } 
} 

Answer 1

STEP1： -聲明Boolean全局變量和SharePrefernce ....

private boolean flag=PreferenceManager.getDefaultSharedPreferences(this).getBoolean("flag", false); 

STEP2獲得的價值： -稱這種現象onCreate()方法...

conti.setEnabled(flag); 

STEP3： -坐落在的onClick（）方法....

case: R.id.button1: 
if(!flag){ 
    flag=true; 
    conti.setEnabled(flag); 
    PreferenceManager.getDefaultSharedPreferences(this).edit().putBoolean("flag", flag).commit(); 
    } 
break; 

STEP4： -最後使用sharePrefernce存儲該boolean變量.....

Answer 2

的幫助下sharedprefrence可以實現這個例子。

SharedPreferences sharedPreferences = getSharedPreferences("myPref", MODE_PRIVATE); 
     SharedPreferences.Editor editor = sharedPreferences.edit(); 
     editor.putBoolean("enableButton", true); 
     editor.commit(); 

把這個代碼放在啓用按鈕。

SharedPreferences sharedPreferences = getSharedPreferences("myPref", MODE_PRIVATE); 
     flag = sharedPreferences.getBoolean("enableButton", false); 
     if (flag) { 
      conti.setEnabled(true); ; 
     }
