任意の助けてください...

をされ、このエラーを取得

Answer 1

メソッドgetCount()を次のように変更します。

public int getCount() { 
    return mThumbIds.length(); 
} 

希望すると助かります！

Answer 2

配列の長さが55であれば、インデックス0からインデックスarray.length-1にJavaのスタートでの配列は、その後でループする配列の最後のインデックスは、この変更がお手伝いします54 あるべきだからです。

public int getCount() { 
    return mThumbIds.length(); 
} 

Answer 3

あなたは配列を使用しています。それで、あなたは2つの値にぶつかります。長さとインデックス例：この時点で

ArrayList<String> my_array = new ArrayList<String>(); 
// Add stuff to it. 
my_array.add("Ajeet"); 
my_array.add("Harry"); 
my_array.add("Chaitanya"); 
my_array.add("Steve"); 
my_array.add("Anuj"); 

は、my_arrayでは5の長さを持っていますが、最後に、「Anuj」、あなたは配列の最後の項目を求めるときに、あなたが何かを使用する必要がありますインデックス4を有します。以下のような：

String last = my_array.get(my_array.length - 1);
