私のコードに問題があります。誰でも助けてくれますか？video＆image viewPager
私はそれを行う自動または手動で
私はviewpagerに画像や動画の一覧を表示したいメッセンジャーアプリ
のようにアプリのプレイの話をする必要があるが、私はいくつかの問題
まず直面した：
を画像のページが表示され、次のページがビデオを再生するときページャが私が使用した次のフラグメントをロードするため、画像を表示するときにビデオのサウンドが再生されます mViewPager.setOffscreenPageLimit（0）;しかし、私は任意のもの
2つ目をしませんでした。
私はビデオからの画像に手動で移動したときに、私は、この発見解決策を検索するときにビデオが再生を停止しない：
public void setUserVisibleHint(boolean isVisibleToUser) {
super.setUserVisibleHint(isVisibleToUser);
if (this.isVisible())
{
if (!isVisibleToUser) // If we are becoming invisible, then...
{
//player.release();}}}}
が、それはだがプレーヤーを停止しますが、次のページにビデオがある場合は再生されません この問題をどうやって解決できますか？

ビデオ用に別の断片を、画像用に別の断片を持つ方がよいと思います。 – Ibrahim
私はこれを行うが、それは、2つのビデオの音が画像 –
を表示するときに 'fillData（ポストビュー、depate）と呼ばれるので、これが起こっpalyingさも同時に再生し、2本のビデオがあるときに問題を抱えているにもあります;' onCreatViewで'surfaceCreated'の中でそれを使用しようとするかもしれないすべてのビデオを呼び出し、' surfaceDestroyed'の中でそれを停止します – Ibrahim
