    <p>What you need to do is store the lines inside an arraylist and then read the arraylist onDraw(). try this code for your View Class:</p> <pre><code>import android.content.Context; import android.graphics.Canvas; import android.graphics.Color; import android.graphics.Paint; import android.util.AttributeSet; import android.view.MotionEvent; import android.view.View; import java.util.ArrayList; class Line { float startX, startY, stopX, stopY, float joinX, joinY = 0; public Line(float startX, float startY, float stopX, float stopY) { this.startX = startX; this.startY = startY; this.stopX = stopX; this.stopY = stopY; } public Line(float startX, float startY) { // for convenience this(startX, startY, startX, startY); } } public class DrawView extends View { Paint paint = new Paint(); ArrayList&lt;Line&gt; lines = new ArrayList&lt;Line&gt;(); public DrawView(Context context, AttributeSet attrs) { super(context, attrs); paint.setAntiAlias(true); paint.setStrokeWidth(6f); paint.setColor(Color.BLACK); paint.setStyle(Paint.Style.STROKE); paint.setStrokeJoin(Paint.Join.ROUND); } @Override protected void onDraw(Canvas canvas) { for (Line l : lines) { canvas.drawLine(l.startX, l.startY, l.stopX, l.stopY, paint); } } @Override public boolean onTouchEvent(MotionEvent event) { if (event.getAction() == MotionEvent.ACTION_DOWN) { if (joinX &lt;= 0 || joinY &lt;= 0) lines.add(new Line(event.getX(), event.getY())); else lines.add(new Line(joinX, joinY); return true; } else if ((event.getAction() == MotionEvent.ACTION_MOVE) &amp;&amp; lines.size() &gt; 0) { Line current = lines.get(lines.size() - 1); current.stopX = event.getX(); current.stopY = event.getY(); Invalidate(); return true; } else if ((event.getAction() == MotionEvent.ACTION_UP) &amp;&amp; lines.size() &gt; 0 { Line current = lines.get(lines.size() - 1); current.stopX = event.getX(); current.stopY = event.getY(); joinX = event.getX(); joinY = event.getY(); Invalidate(); return true; } else { return false; } } } </code></pre>

    2. COI have updated the code. Basically what you want to do is get the stopX and stopY of your line and use them for your startX and startY of your next line. I have included an extra line to check it the line is the first line drawn.

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.
