Java – Android simulate key press

androidjavakeykeypresssimulate

How can I programmatically simulate a key press on a Droid? I would like to mimic a manual key press (appearing on the droid that someone is pressing a key but it is being done programmatically).

There are solutions out there involving IWindowManager, but that isn't an option anymore in the new SDK.

You can use instrumentation, ie following code called from onCreate of your activity will cause menu to be opened and closed multiple times:

    new Thread(new Runnable() {         
        @Override
        public void run() {
            try {
            Instrumentation inst = new Instrumentation();
            for ( int i = 0; i < 10; ++i ) {
                inst.sendKeyDownUpSync(KeyEvent.KEYCODE_MENU);
                Thread.sleep(2000);
                inst.sendKeyDownUpSync(KeyEvent.KEYCODE_BACK);
                Thread.sleep(2000);
            }
            }
            catch(InterruptedException e){
            }
        }   
    }).start();

...but I am not sure if this is what you are after

Java – Sort a Map by values

Here's a generic-friendly version:

public class MapUtil {
    public static <K, V extends Comparable<? super V>> Map<K, V> sortByValue(Map<K, V> map) {
        List<Entry<K, V>> list = new ArrayList<>(map.entrySet());
        list.sort(Entry.comparingByValue());

        Map<K, V> result = new LinkedHashMap<>();
        for (Entry<K, V> entry : list) {
            result.put(entry.getKey(), entry.getValue());
        }

        return result;
    }
}
