    <p>I coded a threaded surfaceview. It works but does not seem to refresh well. What I mean by not refresh well is EX: If I move a bitmap position it continues to be drawn at is last location + is new one.</p> <p>Here is my code: </p> <pre><code>public GameView(Context context) { super(context); holder=getHolder(); currentScreen=new TestScreen(); currentScreen.Load(this.getResources()); } protected void Resume() { isRunning=true; renderThread=new Thread(this); renderThread.start(); } public void run() { while(isRunning) { gametime=lasttime-System.nanoTime(); lasttime=System.nanoTime(); if(!holder.getSurface().isValid()) continue; if(!(currentScreen==null)) { currentScreen.Update(gametime); Canvas cv=holder.lockCanvas(); currentScreen.Draw(cv, gametime); holder.unlockCanvasAndPost(cv); } } } public void pause() { isRunning=false; while(true) { try { renderThread.join(); } catch (InterruptedException e) { } break; } renderThread=null; } </code></pre> <p>}</p> <p>The Screen class code:</p> <p>{</p> <pre><code>public void Load(Resources resources) { square=BitmapFactory.decodeResource(resources, R.drawable.square); x=y=0; super.Load(resources); } @Override public void Update(long gametime) { x++; super.Update(gametime); } @Override public void Draw(Canvas cv, long gametime) { cv.drawBitmap(square, x, y, null); super.Draw(cv, gametime); } </code></pre> <p>}</p> <p>I tried without the Screen class method but it does the same thing. Am I missing some line to clear the screen?</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.

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).
