    <p>I am working on a project which is aboot drawing roads and displaying some informations about the roads. The issue is that I am using so many geopoints( 5.000-10.000 +) and drawing line points to points and showing the roads with different colors, <strong>so the map is too slow.</strong> I did some configurations about my application but still too slow. Do you have any idea about solving my problem and being the performance better?</p> <p>Here is the my code.</p> <pre><code>for (int t = 0; t &lt; roads.size(); t++) { for (int i = 0; i &lt; roads.get(t).size() - 1; i++) { //bounds up-bottom-right-left to draw roads if (boundBox[0] &gt;= roads.get(t).get(i) .getLatitudeE6() &amp;&amp; boundBox[1] &gt;= roads.get(t).get(i) .getLongitudeE6() &amp;&amp; boundBox[2] &lt;= roads.get(t).get(i) .getLatitudeE6() &amp;&amp; boundBox[3] &lt;= roads.get(t).get(i) .getLongitudeE6()) { MyOverlay mOverlay = new MyOverlay(); mOverlay.setColor(Color.GREEN); mOverlay.setWidth(4); mOverlay.setPair(roads.get(t).get(i), roads.get(t).get(i + 1)); mapOverlays.add(mOverlay); } } } </code></pre> <hr> <pre><code> class MyOverlay extends Overlay { GeoPoint gp1 = new GeoPoint(0, 0); GeoPoint gp2 = new GeoPoint(0, 0); int colr=0,width=0; public MyOverlay() { } public void draw(Canvas canvas, MapView mapv, boolean shadow) { super.draw(canvas, mapv, false); Paint mPaint = new Paint(); mPaint.setDither(true); mPaint.setColor(colr); mPaint.setStyle(Paint.Style.FILL_AND_STROKE); mPaint.setStrokeJoin(Paint.Join.ROUND); mPaint.setStrokeCap(Paint.Cap.ROUND); mPaint.setStrokeWidth(width); Point p1 = new Point(); Point p2 = new Point(); Path path = new Path(); Projection projection = mapv.getProjection(); projection.toPixels(gp1, p1); projection.toPixels(gp2, p2); path.moveTo((float) p2.x, (float) p2.y); path.lineTo((float) p1.x, (float) p1.y); // canvas.drawBitmap(markerBitmap, point.x, point.y, null); canvas.drawPath(path, mPaint); //canvas.drawBitmap(bitmap, src, dst, paint); } public void setPair(GeoPoint gpone, GeoPoint gptwo) { gp1 = gpone; gp2 = gptwo; } public void setColor(int clr) { colr=clr; } public void setWidth(int w) { width=w; } } </code></pre> <p>Is there anyone to solve my issue ?</p>

    1. COsome coding of how you are implementing these 5000-10000+ will be useful, because maybe you are not implementing it in efficient way

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.
