最初に番号を表示でき、別のテキストボックスで不在着信番号、受信または発信番号を日付とともに表示できる2つのテキストボックスを備えたカスタムListViewが必要です。ListViewの2行目に日付と通話タイプを表示できますが、試してみると番号を表示するには、次のエラーが発生します。

ここで、ListをString[]
lviewAdapter = new ListViewAdapter(this, timeArray, timeArray);に変換しましたが、両方のプリントが Typeとdateを呼び出す書き込みを行うと出力を取得できます が、書き込む
lviewAdapter = new ListViewAdapter(this, timeArray, timeArray); とArrayIndexoutOfBoundExceptionが返されます

これはランダムな推測ですが、配列の 1 つが異なるサイズであると考えています。これにより、title.length > description.length を返す場合に表示されるエラーが発生します。

存在するビューの数を返す getCount() が呼び出されたときの推論は問題ありません。title.length = 5 と仮定します。ListView は 5 つのビューを生成する必要があるため、位置 =1...5 に対して getView を呼び出します。たとえば、description.length = 3 の場合、getView() で呼び出し時に position = 4 で例外が発生します。

holder.txtViewDescription.setText(description[position]);

lviewAdapter = new ListViewAdapter(this, numArray, timeArray);
System.out.println("adapter => "+lviewAdapter.getCount());
lview.setAdapter(lviewAdapter);
lview.setOnItemClickListener(this);

上記のコードを置き換えます

if(timeArray.length > 0 )
{
   lviewAdapter = new ListViewAdapter(this, numArray, timeArray);
   System.out.println("adapter => "+lviewAdapter.getCount());
   lview.setAdapter(lviewAdapter);
   lview.setOnItemClickListener(this);
}
