こんにちは、最近、私のRubyウェブサイトのRuby用のAndroidアプリケーションを構築し始めました。両方に新しいので、そのすべての混乱。私のアプリがプルダウンリフレッシュを追加してインテントを開始しようとした後で私のwebviewを表示しなくなるため、私は止まっています。プルダウンを追加しようとするとWebviewクラッシュが発生するRefresh
これはこれは私のactivity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context="biz.bdtp.bpin.MainActivity">
<ProgressBar
android:layout_centerHorizontal="true"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_gravity="center_vertical|center_horizontal"
android:id="@+id/progressBar1"/>
<WebView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/web1"
android:layout_alignParentEnd="true"
android:layout_alignParentTop="true"
android:layout_alignParentStart="true"
android:layout_alignParentBottom="true" />
<com.handmark.pulltorefresh.library.PullToRefreshWebView
android:id="@+id/pull_to_refresh_webview"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:cacheColorHint="#00000000"
android:divider="#19000000"

android:fastScrollEnabled="false"
android:footerDividersEnabled="false"
android:headerDividersEnabled="false"
android:scrollbars="none"

/>
</RelativeLayout>
であり、これは事前に私のマニフェスト
<?xml version="1.0" encoding="utf-8"?>

<uses-permission android:name="android.permission.INTERNET" />

android:theme="@style/AppTheme">

ですどこでも。しかし、ちょっと固まって、最終的にすべてのエラーを取り除いて、他に何がグーグルになるか分からない。
