    <p>Here is implementation of WebView containing another "Title bar" view at top of it.</p> <p>How it looks:</p> <p><img src="https://i.stack.imgur.com/6P6SB.png" alt=""></p> <p>Red bar + 3 buttons is a "Title bar", below is web view, all is scrolled and clipped together in one rectangle.</p> <p>It's clean, short, works all way from API 8 to 16 and up (with small effort it can work also on API&lt;8). It doesn't use any hidden functions such as WebView.setEmbeddedTitleBar.</p> <pre><code>public class TitleWebView extends WebView{ public TitleWebView(Context context, AttributeSet attrs){ super(context, attrs); } private int titleHeight; @Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec){ super.onMeasure(widthMeasureSpec, heightMeasureSpec); // determine height of title bar View title = getChildAt(0); titleHeight = title==null ? 0 : title.getMeasuredHeight(); } @Override public boolean onInterceptTouchEvent(MotionEvent ev){ return true; // don't pass our touch events to children (title bar), we send these in dispatchTouchEvent } private boolean touchInTitleBar; @Override public boolean dispatchTouchEvent(MotionEvent me){ boolean wasInTitle = false; switch(me.getActionMasked()){ case MotionEvent.ACTION_DOWN: touchInTitleBar = (me.getY() &lt;= visibleTitleHeight()); break; case MotionEvent.ACTION_UP: case MotionEvent.ACTION_CANCEL: wasInTitle = touchInTitleBar; touchInTitleBar = false; break; } if(touchInTitleBar || wasInTitle) { View title = getChildAt(0); if(title!=null) { // this touch belongs to title bar, dispatch it here me.offsetLocation(0, getScrollY()); return title.dispatchTouchEvent(me); } } // this is our touch, offset and process me.offsetLocation(0, -titleHeight); return super.dispatchTouchEvent(me); } /** * @return visible height of title (may return negative values) */ private int visibleTitleHeight(){ return titleHeight-getScrollY(); } @Override protected void onScrollChanged(int l, int t, int oldl, int oldt){ super.onScrollChanged(l, t, oldl, oldt); View title = getChildAt(0); if(title!=null) // undo horizontal scroll, so that title scrolls only vertically title.offsetLeftAndRight(l - title.getLeft()); } @Override protected void onDraw(Canvas c){ c.save(); int tH = visibleTitleHeight(); if(tH&gt;0) { // clip so that it doesn't clear background under title bar int sx = getScrollX(), sy = getScrollY(); c.clipRect(sx, sy+tH, sx+getWidth(), sy+getHeight()); } c.translate(0, titleHeight); super.onDraw(c); c.restore(); } } </code></pre> <p>Usage: put your title bar view hierarchy inside of &lt;WebView&gt; element in layout xml. WebView inherits ViewGroup, so it can contain children, despite of ADT plugin complaining that it can't. Example:</p> <pre><code>&lt;com.test.TitleWebView android:id="@+id/webView" android:layout_width="match_parent" android:layout_height="match_parent" android:layerType="software" &gt; &lt;LinearLayout android:id="@+id/title_bar" android:layout_width="wrap_content" android:layout_height="wrap_content" android:background="#400" &gt; &lt;Button android:id="@+id/button2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Button" /&gt; &lt;Button android:id="@+id/button3" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Button" /&gt; &lt;Button android:id="@+id/button5" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Button" /&gt; &lt;/LinearLayout&gt; &lt;/com.test.TitleWebView&gt; </code></pre> <p>Note usage of layerType="software", WebView in hardware on API 11+ isn't properly animated and drawn when it has hw layer.</p> <p>Scrolling works perfectly, as well as clicks on title bar, clicks on web, selecting text in web, etc.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
