androidandroid-fragments
When I'm showing one fragment (which is full screen with #77000000 background) over another fragment (let's call it main), my main fragment still reacts to clicks (we can click a button even if we don't see it).
Question: how to prevent clicks on first (main) fragment?
EDIT
Unfortunately, I can't just hide main fragment, because I'm using transparent background on second fragment (so, user can see what located behind).
Thanks to Code Shogun, whose code I adapted to my situation.
Let your activity implementOnClickListener as usual:
public class SelectFilterActivity extends Activity implements OnClickListener {
private static final int SWIPE_MIN_DISTANCE = 120;
private static final int SWIPE_MAX_OFF_PATH = 250;
private static final int SWIPE_THRESHOLD_VELOCITY = 200;
private GestureDetector gestureDetector;
View.OnTouchListener gestureListener;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
/* ... */
// Gesture detection
gestureDetector = new GestureDetector(this, new MyGestureDetector());
gestureListener = new View.OnTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
return gestureDetector.onTouchEvent(event);
}
};
}
class MyGestureDetector extends SimpleOnGestureListener {
@Override
public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
try {
if (Math.abs(e1.getY() - e2.getY()) > SWIPE_MAX_OFF_PATH)
return false;
// right to left swipe
if(e1.getX() - e2.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) {
Toast.makeText(SelectFilterActivity.this, "Left Swipe", Toast.LENGTH_SHORT).show();
} else if (e2.getX() - e1.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) {
Toast.makeText(SelectFilterActivity.this, "Right Swipe", Toast.LENGTH_SHORT).show();
}
} catch (Exception e) {
// nothing
}
return false;
}
@Override
public boolean onDown(MotionEvent e) {
return true;
}
}
}
Attach your gesture listener to all the views you add to the main layout;
// Do this for each view added to the grid
imageView.setOnClickListener(SelectFilterActivity.this);
imageView.setOnTouchListener(gestureListener);
Watch in awe as your overridden methods are hit, both the onClick(View v) of the activity and the onFling of the gesture listener.
public void onClick(View v) {
Filter f = (Filter) v.getTag();
FilterFullscreenActivity.show(this, input, f);
}
The post 'fling' dance is optional but encouraged.
See forum post Any way to view Android screen remotely without root? - Post #9.
adb tcpip 5555. This makes the device to start listening for connections on port 5555;adb shell netcfg or adb shell ifconfig with 6.0 and higher;adb connect <DEVICE_IP_ADDRESS>:5555. This connects to the server we set up on the device on step 2;To switch the server back to the USB mode, run adb usb, which will put the server on your phone back to the USB mode. If you have more than one device, you can specify the device with the -s option: adb -s <DEVICE_IP_ADDRESS>:5555 usb.
No root required!
To find the IP address of the device: run adb shell and then netcfg. You'll see it there.
To find the IP address while using OSX run the command adb shell ip route.
WARNING: leaving the option enabled is dangerous, anyone in your network can connect to your device in debug, even if you are in data network. Do it only when connected to a trusted Wi-Fi and remember to disconnect it when done!
@Sergei suggested that line 2 should be modified, commenting: "-d option needed to connect to the USB device when the other connection persists (for example, emulator connected or other Wi-Fi device)".
This information may prove valuable to future readers, but I rolled-back to the original version that had received 178 upvotes.
On some device you can do the same thing even if you do not have an USB cable:
It should show the IP addressadb connect <DEVICE_IP_ADDRESS>:5555Using Android Studio there is a plugin allowing you to connect USB Debugging without the need of using any ADB command from a terminal.

Set
clickableproperty on the second fragment's view to true. The view will catch the event so that it will not be passed to the main fragment. So if the second fragment's view is a layout, this would be the code:
