これらの行を/res/drawable/listview_main.xmlレイアウトに入れます：android:listSelector="@drawable/seletor2"とセレクタcreateam（ポルトガル語のseletor）。しかし何らかの理由でそれがうまくいかず、プログラムでリストビューセレクタを呼び出そうとしました。繰り返しますが、リストビュー内のアイテムをクリックしたときにセレクタが表示されません（まだ透明で、色はありません）。なぜこれが起こっているのか分かりません。また、私はlistview.setDrawSelectorOnTop(true);を書いています。助けが必要です。何らかの理由でリストビューセレクタが動作しない

あなたがアイテムの他の状態を必要といけない原因
あなたのセレクタからこの行を削除してみてください。<商品のandroid：state_window_focused = "false" のアンドロイド：state_selected = "true" を アンドロイド：描画可能= "@アンドロイド：カラー/透明" /> –
@SandeepShabd私はこの行を削除し、それまだ動作しません！ –
