    <p>I want to create a program, that open documents without external app. I need this, because i want to scroll the document with the phones orientation(Pitch and Roll). I create a button on the bottom of the screen, and when i hold down the button, i can scroll the document too. If i release the button, i can't scroll it. So, if i open the document with external app, my button disappears, and the sensorManager works neither.</p> <p>Have someone any idea to solve this problem. Or have someone any idea, how to scroll the document, opened in an external app, with my phones orientation?</p> <p>(Sorry for my English)</p> <p>This is my manifest:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.orientationscrolling" android:versionCode="1" android:versionName="1.0" &gt; &lt;uses-sdk android:minSdkVersion="8" android:targetSdkVersion="17" /&gt; &lt;uses-permission android:name="android.permission.INTERNET" /&gt; &lt;application android:allowBackup="true" android:icon="@drawable/ic_launcher" android:label="@string/app_name" android:theme="@style/AppTheme" &gt; &lt;activity android:name="com.example.orientationscrolling.MainActivity" android:label="@string/app_name" &gt; &lt;intent-filter&gt; &lt;action android:name="android.intent.action.MAIN" /&gt; &lt;category android:name="android.intent.category.LAUNCHER" /&gt; &lt;/intent-filter&gt; &lt;/activity&gt; &lt;/application&gt; &lt;/manifest&gt; </code></pre> <p>This is my Layout:</p> <pre><code>&lt;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:orientation="vertical" &gt; &lt;WebView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/webView1" android:layout_width="match_parent" android:layout_height="match_parent" /&gt; &lt;LinearLayout 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:gravity="bottom" android:orientation="vertical" &gt; &lt;Button android:id="@+id/mybutt" android:layout_width="wrap_content" android:layout_height="wrap_content" android:textSize="25sp" android:text="Scroll!!" android:layout_gravity="right"/&gt; &lt;/LinearLayout&gt; </code></pre> <p></p> <p>This is my Code:</p> <pre><code>protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); button = (Button) findViewById( R.id.mybutt ); String pdf = "http://www.pc-hardware.hu/PDF/konfig.pdf"; String doc="&lt;iframe src='http://docs.google.com/gview?embedded=true&amp;url=http://www.pc-hardware.hu/PDF/konfig.pdf' width='100%' height='100%' style='border: none;'&gt;&lt;/iframe&gt;"; webView = (WebView) findViewById(R.id.webView1); webView.getSettings().setJavaScriptEnabled(true); webView.getSettings().setPluginsEnabled(true); webView.getSettings().setAllowFileAccess(true); webView.loadData( doc , "text/html", "UTF-8"); } </code></pre>
