お時間をいただきありがとうございます。私のアプリのTEHのWebViewにロードされている私のページで は、写真のアップロードです：Android Webviewギャラリーまたはカメラから画像をアップロード
<form action="?pb=1" method="post" enctype="multipart/form-data">
<input id="pbbutton" type="file" title="Profielbild ändern" name="datei" onchange="this.form.submit()">
<label id="pblabel" for="pbbutton"><img id="profilbild" title="Profilbild ändern" class="userpb" src="./users/<?php echo htmlspecialchars($userid); ?>/pb" alt="Bild nicht gefunden" onerror="this.src='./img/no_pb.png';"></label>
</form>
あなたは通常、あなたのギャラリーなどのいずれかをpicに場合は、写真をuploades ...
どのように私は、作ることができます私がこの入力をクリックすると、画像を選択でき、websideが変更を検出する（js：onchange） 私はすでに何か試しましたが、選択した後で画像をアップロードしません。 ここimguploadのための私のコード：
