gesturedetector

I have two containers in a stack and both containers have GestureDetector.The OnTap for the first container is working fine but it's not working with another container. The first container is the image and the second one is the green background aligned partially over the first container. new Stack( alignment: Alignment(0.0, 1.44), children: <Widget>[ GestureDetector( onTap: () => _openImage(context), child: Container( width: 340.0, foregroundDecoration: new BoxDecoration( color: Color.fromRGBO(155, 85, 250, 0.55)), height: 240.0, child: FadeInImage.assetNetwork( placeholder: 'assets/dimlight

My question is simple, where's the onUp event when implementing a GestureListener? I has a lot of events on the gesturedetector, and cannot just consume the onUp event of the listener, cause one of events are the onSingleTapConfirmed that needs it. adamwong246 Try using onFling() . Seems like a weird name but for me, it works as the onUp() method would logically work. Or try this method... @Override public boolean onTouchEvent(MotionEvent me) { Log.v("ADAM", "ontouch: " + me.getAction()); if(me.getAction() == 0){ Log.v("ADAM", "Down"); } else if (me.getAction() == 1) { Log.v("ADAM", "Up"); }

The challenge of attaching a GestureDetector to a ListPreference is 2-fold: Getting a handle to a ListPreference that's only defined in a preferences.xml (i.e. not instantiated in Java code). ListPreference is neither a View nor Activity subclass. Is it possible at all to attach a GestureDetector to a ListPreference ? If so, how would one go about this? Where would I write the code to instantiate GestureDetector and implement the listener? Unless I didn't quite catch the question correctly, the answer is probably simpler than you might think. The source code for ListPreferece teaches that it's

Good moorning : I have an ImageView in my Activity and I setted the OntOuchListner() to my ImageView, which means that I implemented that interface for my ImageView like this : public class mapActivity extends Activity { //-------------------------------------- private ImageView imageView; /** * Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); imageView = (ImageView) this.findViewById(R.id.imageView1); AddImageViewEvents(); } private void AddImageViewEvents() { imageView

Here is the code to display listview items and onclick listener action. ListView list = (ListView) findViewById(R.id.list); ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource( this, R.array.list, android.R.layout.simple_list_item_1); list.setAdapter(adapter); list.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(AdapterView<?> l, View v, int position, long id) { String sel = (String) adapterView .getItemAtPosition(position); Toast.makeText(MyExample.this, "Your selection: " + sel, Toast.LENGTH_SHORT).show(); if (sel.equals("Photos"){
