你想做什麼？提供更多細節。 – Naddy

我想加載button1，如果beginner1_pref = true，然後隱藏button2然後在beginner1_pref = false顯示button2然後隱藏button1 – John

給你的'活動'代碼。 – Naddy

的問題是，你還沒有第二Button無形。您剛剛初始化了第一個Button，但您的第二個Button顯然存在於您的佈局中。它不會隱藏，除非你明確隱藏它。修改你的代碼是這樣的：

if (beginner1_pref == false){ 
     beginner1Check = (Button) findViewById(R.id.btnBeginner1Check); 
     beginner1 = (Button) findViewById(R.id.btnBeginner1); 
     beginner1.setVisibility(View.INVISIBLE);//You can replace it with VIEW.GONE depending on your needs. 
     beginner1Check.setOnClickListener(myOnlyhandler); 
    } else if (beginner1_pref == true){ 
     beginner1 = (Button) findViewById(R.id.btnBeginner1); 
     beginner1Check = (Button) findViewById(R.id.btnBeginner1Check); 
     beginner1Check.setVisibility(View.INVISIBLE); 
     beginner1.setOnClickListener(myOnlyhandler); 
    }
