android-ui

I have a strange problem with an AlphaAnimation . It is supposed to run repeatedly when an AsyncTask handler is called. However, the first time the handler is called in the Activity , the animation won't start unless I touch the screen or if the UI is updated (by pressing the phone's menu button for example). The strange part is that once the animation has run at least once, it will start without problem if the handler is called again. Here's what the code looks like: // AsyncTask handler public void onNetworkEvent() { this.runOnUiThread(new Runnable() { @Override public void run() {

I have a problem with the Android MediaPlayer when changing the dataSource of the player. According the specification of the MediaPlayer ( http://developer.android.com/reference/android/media/MediaPlayer.html ) I have to reset the player when changing the dataSource . This works fine, but as soon as the channelChanged method is called twice in quick succession the MediaPlayer.reset freezes the UI. I profile the code as seen here: public void channelChanged(String streamingUrl) { long m1 = System.currentTimeMillis(); mMediaPlayer.reset(); long m2 = System.currentTimeMillis(); try { mMediaPlayer

So I wanted to have a TextView with a cool border around it. I couldn't find any standard way of doing it, so I came up with this: @drawable/custom_bg_1: A blue rounded shape <?xml version="1.0" encoding="UTF-8"?> <shape xmlns:android="http://schemas.android.com/apk/res/android"> <solid android:color="#439CC8"/> <corners android:radius="3dp" /> <padding android:left="10dp" android:top="10dp" android:right="10dp" android:bottom="10dp" /> </shape> @drawable/custom_bg_2: A white rounded shape <?xml version="1.0" encoding="UTF-8"?> <shape xmlns:android="http://schemas.android.com/apk/res/android">

getActionView() for action bar was introduced in API 11 , If I want backward compatibility what is the alternative for getActionView() ? e.g. public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.action_bar_menu, menu); final MenuItem item = menu.findItem(R.id.menuitem); item.getActionView() //Works from API level 11 return true; } For backwards compatibility you can use either ActionBarCompat or ActionBarScherlock . In both cases you can use the method getActionView(). You have to be sure that the import, in the first case is from the compatibility library ( android

I would like to know how to style the drop down popup of the Android 4.0 SearchView ? I'm using the Theme.Sherlock.Light.DarkActionBar , but I don't know how to style the drop down search into a white background and a black text? For some reason theming using the "searchAutoCompleteTextView" wasn't working for me either. So I solved it using the following code when setting up my SearchView: Note: This is all done with the android v7 support/AppCompat library public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.search_menu, menu); MenuItem searchItem = menu.findItem

This is the Android equivalent of this iOS question. Trying to create a view that contains a MapView at about 20% of the screen (under an ActionBar...) and the rest of the screen is a ScrollView that when scrolling down, overlaps on top of the MapView and hides it. In short like FourSquare's Android app. Any ideas? I've made an implementation based on AndroidSlidingUpPanel (many thanks to this project).
