    <p>I'm trying to write my own layout class. But I'm having trouble with the onLayout. If I extend LinearLayout and have it do onLayout and I call super.onMeasure() in my onMeasure, everything works. But it's not working extending ViewGroup. What's showing is the first left most child gets rendered correctly but the rest don't show up or are not the right size.</p> <pre><code>import android.content.Context; import android.content.res.TypedArray; import android.util.AttributeSet; import android.view.View; import android.view.ViewGroup; import android.view.ViewGroup.LayoutParams; class ManualPanel extends ViewGroup { private int totalDivs; private int[] sizesArr; public ManualPanel(final Context context) { this(context, null); } public ManualPanel(final Context context, final AttributeSet attrs) { super(context, attrs); final TypedArray a = context.obtainStyledAttributes(attrs, R.styleable.ManualPanel); final String[] sizeStr = a.getString(R.styleable.ManualPanel_sizes).split("/"); final String[] fracArr = sizeStr[0].split(","); a.recycle(); int sum = 0; sizesArr = new int[fracArr.length]; for (int i = 0; i &lt; sizesArr.length; i++) { sizesArr[i] = Integer.valueOf(fracArr[i]); sum += sizesArr[i]; } totalDivs = Math.max(sum, Integer.valueOf(sizeStr[1])); } @Override protected void onMeasure(final int widthMeasureSpec, final int heightMeasureSpec) { final int children = getChildCount(); final int totalWidth = MeasureSpec.getSize(widthMeasureSpec); final int totalHeight = MeasureSpec.getSize(heightMeasureSpec); totalDivs = Math.max(totalDivs, children); final int[] arr = IntArray.copyOf(sizesArr, children); final int width[] = new int[children]; int sum = 0; for (int i = 0; i &lt; children; i++) { width[i] = (arr[i] * totalWidth) / totalDivs; sum += width[i]; } for (int i = 0, diff = totalWidth - sum; diff &gt; 0; i = ++i % children) { width[i]++; diff--; } for (int i = 0; i &lt; children; i++) { final View view = getChildAt(i); final LayoutParams lp = view.getLayoutParams(); lp.width = width[i]; view.setLayoutParams(lp); view.measure(MeasureSpec.EXACTLY | lp.width, MeasureSpec.EXACTLY | totalHeight); // view.measure(MeasureSpec.AT_MOST | lp.width, MeasureSpec.AT_MOST | totalHeight); } setMeasuredDimension(totalWidth, totalHeight); } @Override protected void onLayout(boolean changed, int l, int t, int r, int b) { final int children = getChildCount(), height = getMeasuredHeight(); for (int i = 0; i &lt; children; i++) { final View view = getChildAt(i); if (view.getVisibility() != View.VISIBLE) continue; final int width = view.getMeasuredWidth(); view.layout(l, 0, left + width, height); l += width; } } } </code></pre>

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.
