    <p>I'm new to Android programming and to stack overflow, and I need to slow down the animation speed of a SlidingDrawer in my app.</p> <p>I've already subclassed SlidingDrawer like this:</p> <pre><code>import android.content.Context; import android.util.AttributeSet; import android.view.View; import android.widget.SlidingDrawer; public class WrappingSlidingDrawer extends SlidingDrawer { public WrappingSlidingDrawer(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); int orientation = attrs.getAttributeIntValue("android", "orientation", ORIENTATION_VERTICAL); mTopOffset = attrs.getAttributeIntValue("android", "topOffset", 0); mVertical = (orientation == SlidingDrawer.ORIENTATION_VERTICAL); } public WrappingSlidingDrawer(Context context, AttributeSet attrs) { super(context, attrs); int orientation = attrs.getAttributeIntValue("android", "orientation", ORIENTATION_VERTICAL); mTopOffset = attrs.getAttributeIntValue("android", "topOffset", 0); mVertical = (orientation == SlidingDrawer.ORIENTATION_VERTICAL); } @Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { int widthSpecMode = MeasureSpec.getMode(widthMeasureSpec); int widthSpecSize = MeasureSpec.getSize(widthMeasureSpec); int heightSpecMode = MeasureSpec.getMode(heightMeasureSpec); int heightSpecSize = MeasureSpec.getSize(heightMeasureSpec); if (widthSpecMode == MeasureSpec.UNSPECIFIED || heightSpecMode == MeasureSpec.UNSPECIFIED) { throw new RuntimeException("SlidingDrawer cannot have UNSPECIFIED dimensions"); } final View handle = getHandle(); final View content = getContent(); measureChild(handle, widthMeasureSpec, heightMeasureSpec); if (mVertical) { int height = heightSpecSize - handle.getMeasuredHeight() - mTopOffset; content.measure(widthMeasureSpec, MeasureSpec.makeMeasureSpec(height, heightSpecMode)); heightSpecSize = handle.getMeasuredHeight() + mTopOffset + content.getMeasuredHeight(); widthSpecSize = content.getMeasuredWidth(); if (handle.getMeasuredWidth() &gt; widthSpecSize) widthSpecSize = handle.getMeasuredWidth(); } else { int width = widthSpecSize - handle.getMeasuredWidth() - mTopOffset; getContent().measure(MeasureSpec.makeMeasureSpec(width, widthSpecMode), heightMeasureSpec); widthSpecSize = handle.getMeasuredWidth() + mTopOffset + content.getMeasuredWidth(); heightSpecSize = content.getMeasuredHeight(); if (handle.getMeasuredHeight() &gt; heightSpecSize) heightSpecSize = handle.getMeasuredHeight(); } setMeasuredDimension(widthSpecSize, heightSpecSize); } private boolean mVertical; private int mTopOffset; </code></pre> <p>}</p> <p>I found this link: <a href="http://groups.google.com/group/android-developers/browse_thread/thread/a7d0102811474bfe" rel="nofollow">How to change animation velocity on SlidingDrawer</a>, and it says that I can find an alternative implementation, or copy the source and modify it. </p> <p>I created SlidingDrawer.java in my own project and pasted the code from <a href="http://www.java2s.com/Open-Source/Android/android-core/platform-frameworks-base/android/widget/SlidingDrawer.java.htm" rel="nofollow">here</a>, but there are errors. There are several lines that reference R.styleable.SlidingDrawer, e.g.</p> <pre><code>TypedArray a = context.obtainStyledAttributes(attrs, R.styleable.SlidingDrawer, defStyle, 0); </code></pre> <p>which Eclipse can't resolve.</p> <p>There are also four member variables (mTop, mBottom, mLeft, mRight) which Eclipse can't resolve.</p> <p>How do I make Eclipse find these resources/variables? I will then be able to edit some variables to result in a slower animation, right?</p>

    1. COhey can you please provide the final custom class, and how you add it into xml, because it is giving me error "InflateException".

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
