Is it possible to create and dispatch custom events in android? The only examples i have seen extend existing events. I want to be able to dispatch an event anywhere that I deem necessary.

I'd like to create an app that allow you to filter incoming call to various answering message with :
"this number is not available" for black listed phone numbers
A formal message for strangers
A informative message about what your doing for friends
I don't know I you can get automatically a call, play a recorded message then wait for the answer and record it. Or maybe there is just a way to interact with the actual answering system so I just have to plug in.

I thought I knew how to catch list selection events in Android and then I regained consciousness. In my situation, I have a ListView that I populate with a custom view, all of the same class (let's call it the NewsChannel() class). NewsChannel consists of a LinearLayout of ImageViews and TextViews. When the list is displayed, the user may select a NewsChannel item in the list; I want to find out which list item was selected. Also, I registered an onClickListener to one of the TextViews and that works fine: when the text is clicked on, an activity is launched which is looking for the position of the NewsChannel item in the list. So, here's what my code looks like:
1. Registering the onClickListener in the ListActivity:
public class NewsListActivity extends ListActivity {...
public void onCreate(Bundle icicle) { super.onCreate(icicle);
setContentView(R.layout.news_list_format); ListView lv = getListView();
lv.setOnItemClickListener(new OnItemClickListener()
{ public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// When clicked, show a toast with the TextView text item_index = position;
Toast.makeText(getApplicationContext(), "item clicked = " + position,
Toast.LENGTH_SHORT).show(); }}); ...
2. The layout for the ListView associated with NewsListActivity:
<?xml version="1.0" encoding="UTF-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/ android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent" android:background="@drawable/wpaper_tile" >
<ListView android:id="@id/android:list" android:layout_width="fill_parent"
android:layout_height="fill_parent" android:layout_alignParentTop="true"
android:dividerHeight="15dp" android:divider="@android:color/transparent"
android:cacheColorHint="@android:color/transparent" android:scrollbars="none" />
<FrameLayout android:layout_width="fill_parent" android:layout_height="55dp"
android:layout_centerHorizontal="true" android:layout_alignParentBottom="true"
android:background="#88000000"/>
<ImageView android:layout_width="fill_parent"
android:layout_height="wrap_content" android:layout_centerHorizontal="true"
android:layout_alignParentBottom="true" android:src="@drawable/phonetop_bg" /> </RelativeLayout>
3. The NewsChannel layout:
<?xml version="1.0" encoding="UTF-8"?> <RelativeLayout xmlns:
android="http://schemas.android.com/apk/res/ android"
android:layout_width="fill_parent" android:layout_height="wrap_content">
<include layout="@layout/news_heading_format"
android:id="@+id/news_heading_header"/>
<ImageView android:id="@+id/news_channel_image" android:layout_width="88dp"
android:layout_height="66dp" android:layout_alignParentLeft="true"
android:layout_below="@id/news_heading_header" android:padding="10dp" />
<TextView android:id="@+id/news_channel_text" android:lines="4"
android:inputType="textMultiLine" android:layout_toRightOf="@id/news_channel_image"
android:layout_below="@id/news_heading_header" android:layout_width="fill_parent"
android:layout_height="wrap_content"/> </RelativeLayout>
When I run the app, the ItemClickListener is never called. However, if NewsChannel were of a simpler type, say, a single ImageView or TextView embedded in the layout, the callback does get called. Any idea what I'm doing wrong? My whole goal is simply to let the activity launched by NewsChannel (not shown) to find out which instance of NewsChannel it was launched from.
I have an activity defined as:

Does anybody have any idea why I get often(but not always) error during the on touch event? Handling touch events is freezed for few seconds(this appears only immediately after application start). Then Error screen appears (choose wait of close). When I choose wait after few seconds screen is starting to process events. I'm using surfaceView with thread for painting. In logcat I get something like : "No window to dispatch pointer action 1".

I had an idea to use Android in the public space to report public works and other problems that need repairs. Android provides a great tool to document and locate problems. Google APIs like Maps and Appengine can link these reports to help direct efforts to make the public space a better place to live. Unfortunately I'm a Java rookie and so lack the skills to even start the coding at this point. How to get this open source application started.
I found event handler: dispatchTouchEvent(MotionEvent) works differently between G1 & emulator when finger is holding on touch screen.
I have a class inherited from RelativeLayout and override public boolean dispatchTouchEvent(MotionEvent event) method. After I touch & hold on the touch screen, in emulator I got MotionEvent.ACTION_DOWN event only. But in G1, I got MotionEvent.ACTION_DOWN first and then MotionEvent.ACTION_MOVE continuously, even if I try my best to hold still my finger tip.
I wonder if this is because there is pressure field in the MotionEvent. Because the blood pressure on finger tip changes continuously with heart beat, so no matter how still my finger is, the pressure value still changes. But I wonder if all kinds of touch screen have pressure factor in their touch event? Will all touch screen driver emit touch event continuously when finger is holding on the screen?

View 2 Replies View RelatedI know how to create and apply styles and themes thanks to http://developer.android.com/guide/topics/ui/themes.html. However, this method only works for our own activity or application. I'd like to create themes that could dress the whole system (i.e. all activities). Of course, I'd like to select one of these theme by programing. If I could customize the status bar as well, it would be perfect. I didn't find out documentation about that.
