 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

You are still using ADT 0.8 which is not compatible with Android 1.5 SDK.
Please install ADT 0.9

2. ADT Layout Editor -- What do warning triangles mean?

This is very much a work in progress, and unfortunately it's not
really documented at this time.

The triangle icon (which is a warning icon) means that you have
requested a particular value for a resource qualifier but no layout
file matching it was found and a default file is used..

For example:
- Edit res/layout/main.xml
- In the top bar above the preview display it should say "Current
config: default"

- Set orientation to landscape => ADT will look for a res/layout-land/main.xml.

- if Found => ADT will switch the edited file to this file (and will
now display "Current config: landscape").
- if not found => a warning icon next to landscape is displayed.
default layout file is still edited.
