我有listview，其中包含textview和複選框。複選框在Android 4.x中不可見，但在Android 5+中可見
我在DialogFragment中顯示ListView。問題是複選框不顯示運行Android版本4.1到4.4.4的設備（模擬器）。但他們通常顯示爲Android 5.0+。我一直在努力解決這個問題好幾個小時。但沒有成功。
有人可以告訴我我做錯了什麼？

我沒有想到這一點。謝謝，我會盡力回覆你。 – Retr0spect101
我做了你說的，但仍然我複選框不可見。我只能看到複選框文本。可能它與主題有關嗎？向後兼容？ – Retr0spect101
你可能需要看看編寫你自己的適配器。 ArrayAdapter只對非常簡單的數據有用。它看起來像 - http://stackoverflow.com/a/40259628/1856361 –
