 How can I programmatically press/release a button? I was playing with
the button.dispatchTouchEvent(motionEvent); but failed to
programmatically generate  the MotionEvent to be passed to the
dispatchTouchEvent

 I found the way to generate the MotionEvent, and it's
MotionEvent.obtain

 i , i have a qustion about onTouch event, I have a layout that
consist of 2 elements, a WebView and on top of it a TextView and then
a custom view, that expand all over the screen and is transparent.
With these i want to carch touch events and delegate to the correct
widget either TextView or WebView depending on the touch event
position (MoseEvent).

[code]
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/
android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent">

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/
android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">

<TextView
android:id="@+id/label"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Type here:"/>

<WebView android:id="@+id/webview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_below="@id/label"/>

</RelativeLayout>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/
android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">

<com.frame.TransparentPanel android:id="@+id/transparent_panel"
android:layout_width="fill_parent"
android:layout_height="fill_parent"/>

</LinearLayout>

</FrameLayout>
[/code]


[code]
public class TransparentPanel extends LinearLayout
{
private Paint innerPaint, borderPaint ;
private List<PointF> pointsToDraw = new ArrayList<PointF>();
private WebView webview;
private Paint touchPaint;

public TransparentPanel(Context context, AttributeSet attrs) {
super(context, attrs);
init();
}

public TransparentPanel(Context context) {
super(context);
init();
}

private void init() {
touchPaint = new Paint();
touchPaint.setARGB(255, 0, 0, 255);
touchPaint .setAntiAlias(true);
touchPaint .setStyle(Style.STROKE);
touchPaint .setStrokeWidth(2);

innerPaint = new Paint();
innerPaint.setARGB(0, 100, 75, 75); //gray
innerPaint.setAntiAlias(true);

borderPaint = new Paint();
borderPaint.setARGB(255, 255, 255, 255);
borderPaint.setAntiAlias(true);
borderPaint.setStyle(Style.STROKE);
borderPaint.setStrokeWidth(2);
}

public void setInnerPaint(Paint innerPaint) {
this.innerPaint = innerPaint;
}

public void setBorderPaint(Paint borderPaint) {
this.borderPaint = borderPaint;
}

@Override
public boolean onTouchEvent(MotionEvent

2. Google Voice integration?

Will Android ever read your already existing contacts info and allows
you to call them using Google Voice just by clicking their name?  All
that "just dial G.V., press 2, press (*) for 4.2 seconds, enter your
social security number backwards, and finally the number you want to
call (which you may not have in your head since it's stored as a
contact)"-- YOWCH.  The only reason I'd like this ability is to be
able to be able to start a call on my cell phone then transfer the
call to my home or work phone when I arrive.  Slickist would be if
it's in the development plans for Android so that you can enter your
G.V. number (if you have one), and it just automatically makes calls
through G.V.
