    <p>I am a college student working on a final project for android development.</p> <p>My project is a simple game of snake where the user can use the accelerometer, or buttons.</p> <p>The way my game view works is I create a grid dynamically, on my "SnakeView" which extends view like such:</p> <pre><code>/** * This is where we paint the grid and the game. */ @Override public void onDraw(Canvas canvas){ super.onDraw(canvas); if(created){ canvas.drawBitmap(mBitmap, 0, 0, mPaintScreen); mBitmap.eraseColor(Color.WHITE); for(int i = 0 ; i &lt; xlength; i++){ for(int j = 0; j &lt; ylength; j++){ int x = i * rectWidth; int y = j * rectHeight; Point p = new Point(i,j); if(snake.contains(p)){ mBitmapCanvas.drawRect(x,y, x + rectWidth, y + rectHeight, mSnakePaint); }else if(walls.contains(p)){ mBitmapCanvas.drawRect(x,y, x + rectWidth, y + rectHeight, mWallPaint); }else if (growBerries.contains(p)){ mBitmapCanvas.drawRect(x,y, x + rectWidth, y + rectHeight, mGrowBerryPaint); } } } } } </code></pre> <p>Basically I have an arraylist that contains the snake and my berries. If the point on the plain is in either arraylist, I paint the rectangle a different color. Otherwise I keep the plane white.</p> <p>For setting rectWidth and height I go in the onSizeChanged method.</p> <pre><code>@Override public void onSizeChanged(int w, int h, int oldW, int oldH){ mBitmap = Bitmap.createBitmap(getWidth(), getHeight(),Bitmap.Config.ARGB_8888); mBitmapCanvas = new Canvas(mBitmap); mBitmap.eraseColor(Color.WHITE); width = w; height = h; rectWidth = width / (xlength-1); rectHeight = height / (ylength-1); invalidate(); } </code></pre> <p>now the issue is the blocks do not format to the correct size accross different devices. I have tested this on the nexus 7 tablet (not sure dimensions but its much larger), and my phone which is a pantech flex. (roughly 4 inches)</p> <p><a href="http://i45.tinypic.com/34r7lsy.png" rel="nofollow noreferrer">myimage http://i45.tinypic.com/34r7lsy.png</a> <a href="http://i46.tinypic.com/fl98hi.png" rel="nofollow noreferrer">myimage2 http://i46.tinypic.com/fl98hi.png</a></p> <p>As you can see, the one on the right, the outer border i created doesn't match up to the screen width. I was wondering why this could be.</p> <p>I definitely know the borders are hugging my grid, it is just that the grid is not spread out to fit the whole width.</p> <p>This should work and the sizes should fit according to screen size. My only guess is that the int w and int h, are rounded off, and they do not protray the actual width and height. xlength and ylength are the number of blocks I want in the x and y direction.</p> <p>I noticed that if I adjust the amount of rectangles, it may fit on one device, but not the other, I just want it to fit perfectly on both!</p>

    1. COWhere do you get all the dimensions from? (xlength, ylength, etc.)

    3. COI suspect you get the dimensions and perform your calculation incorrectly in some way. To make any use of it, you will need to show that piece of code, or better yet: Start by painting the screen without these rects, and see in which part of your calculations the mistakes start happening.

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.
