Constructor Detail

DeviceSelectorDialog

public DeviceSelectorDialog()

Method Detail

newInstance

public static DeviceSelectorDialog newInstance(MediaBrowserCompat mediaBrowser)

Creates a new DeviceSelectorDialog. This is the only way a DeviceSelectorDialog should be created. If creation is not done through this method the DeviceSelectorDialog will be unable to communicate with the MoppyMediaService and will be effectively useless.

Parameters:

mediaBrowser - the MediaBrowserCompat used to communicate with the MoppyMediaService

Returns:

the created DeviceSelectorDialog

onCreate

public void onCreate(@Nullable
                     Bundle savedInstanceState)

Triggered when this DeviceSelectorDialog is created.

Overrides:

onCreate in class DialogFragment

Parameters:

savedInstanceState - If the fragment is being re-created from a previous saved state, this is the state.

See Also:

onCreateDialog(Bundle)

onCreateDialog

public Dialog onCreateDialog(Bundle savedInstanceState)

Triggered when the contained dialog is created. If the dialog was recreated due to a configuration change (e.g. device rotation, mouse plugged in) then this will be called without onCreate(Bundle), otherwise this will be called subsequently to onCreate.

Overrides:

onCreateDialog in class DialogFragment

Parameters:

savedInstanceState - The last saved instance state of the Fragment, or null if this is a freshly created Fragment.

Returns:

Return a new Dialog instance to be displayed by the Fragment.

onStart

public void onStart()

Triggered whenever this DeviceSelectorDialog comes into the foreground from a hidden state (e.g. app minimized, device locked), including when this DeviceSelectorDialog first gets created.

Overrides:

onStart in class DialogFragment

onDestroyView

public void onDestroyView()

Triggered when the contained dialog is destroyed. If the dialog was destroyed due to a configuration change (e.g. device rotation, mouse plugged in) then Fragment.onDestroy() will not be called, but if the dialog was destroyed due to dismissal then onDestroy will be called.

Overrides:

onDestroyView in class DialogFragment

onUsbPermissionIntent

public void onUsbPermissionIntent(Intent intent)

Handles device connection when permission had to be requested first. MUST be called when a MainActivity.ACTION_USB_PERMISSION broadcast is handled by MainActivity's BroadcastReceiver.

Parameters:

intent - the intent associated with the ACTION_USB_PERMISSION broadcast

onDeviceConnectionStateChanged

public void onDeviceConnectionStateChanged()

Updates this DeviceSelectorDialog's available device lists if it is showing, otherwise waits for the next time this DeviceSelectorDialog is shown to refresh. Should be called when either UsbManager.ACTION_USB_DEVICE_ATTACHED or UsbManager.ACTION_USB_DEVICE_DETACHED occurs.

onItemSelected

public void onItemSelected(AdapterView<?> parent,
                           View view,
                           int position,
                           long id)

Triggered when an item in either of the Spinners has been selected.

Specified by:

onItemSelected in interface AdapterView.OnItemSelectedListener

onNothingSelected

public void onNothingSelected(AdapterView<?> parent)

Triggered when the selection disappears from this view. The selection can disappear for instance when touch is activated or when the adapter becomes empty.

Specified by:

onNothingSelected in interface AdapterView.OnItemSelectedListener

onCheckedChanged

public void onCheckedChanged(CompoundButton buttonView,
                             boolean isChecked)

Triggered when the checked state of a CheckBox changes.

Specified by:

onCheckedChanged in interface CompoundButton.OnCheckedChangeListener

updateDevices

public void updateDevices()

Updates the list of available devices in this DeviceSelectorDialog.

getMediaBrowser

public MediaBrowserCompat getMediaBrowser()

Retrieves the MediaBrowserCompat this DeviceSelectorDialog uses to manage devices.

Returns:

the MediaBrowserCompat used to communicate with the MoppyMediaService
