android - MapFragment inside ScrollView inside Fragment

android - MapFragment inside ScrollView inside Fragment - java

My goal is to let MapFragment handle touch event instead of ScrollView.
MapFragment is being added programmatically inside of ScrollView which is inside of Fragment.

mapFragment = new FragmentMap();
getChildFragmentManager().beginTransaction().add(R.id.fragment_map, mapFragment, TAG).commit();
getChildFragmentManager().executePendingTransactions();
FragmentMap looks like this:
public class FragmentMap extends SupportMapFragment {
private OnTouchListener mListener;
private boolean mTouchListener = false;
#Override
public View onCreateView(LayoutInflater layoutInflater, ViewGroup viewGroup, Bundle savedInstance) {
View layout = super.onCreateView(layoutInflater, viewGroup, savedInstance);
TouchableWrapper frameLayout = new TouchableWrapper(getActivity());
frameLayout.setBackgroundColor(getResources().getColor(android.R.color.transparent));
frameLayout.addView(layout);
setListener(new OnTouchListener() {
#Override
public void onTouch() {
//Prevents NullPointerException
}
});
return frameLayout;
}
public void setListener(OnTouchListener listener) {
mListener = listener;
}
public interface OnTouchListener {
public abstract void onTouch();
}
public boolean getTouch() {
return mTouchListener;
}
public class TouchableWrapper extends FrameLayout {
public TouchableWrapper(Context context) {
super(context);
}
#Override
public boolean dispatchTouchEvent(MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
mTouchListener = true;
break;
case MotionEvent.ACTION_UP:
mTouchListener = false;
break;
}
mListener.onTouch();
return super.dispatchTouchEvent(event);
}
}
}
I set listener on a map:
mapFragment.setListener(new FragmentMap.OnTouchListener() {
#Override
public void onTouch() {
scrollView.requestDisallowInterceptTouchEvent(true);
}
});
This is supposed to work when map fragment is declared in the XML layout but when I am adding it programmatically, it doesn't.

To enable or disable intercepting event in a parent view, you have Android's onInterceptTouchEvent(MotionEvent ev) method. But it is propagated from the top-down (i.e. the parent view returns true if it consumed the event, false otherwise) . So create a class extending the ScrollView, and override that method:
#Override
public boolean onInterceptTouchEvent(MotionEvent ev) {
if(checkCoordinateCross(ev, YOUR_TARGET_VIEW_ID)) {
return false;
}
return true;
}
private boolean checkCoordinateCross(MotionEvent ev, int resId) {
View target = findViewById(resId);
if(target == null) {
return false;
}
if(ev.getX() > target.getX() && ev.getX() < target.getX() + target.getWidth() && ev.getY() > target.getY() && ev.getY() < target.getY() + target.getHeight()) {
return true;
}
return false;
}
Note that YOUR_TARGET_VIEW_ID has to be the child of the ScrollView or findViewById(...) will return null.

Android: Button doesn't work, but code doesn't show any error

I'm trying to create a form to capture data, I need to access the camera to take pictures. My problem is when I try to call the camera with imagenButton, it's not working but the code doesn't show any error.
Here's my fragment to declare form:

}
#Override

ActivityCompat.requestPermissions(getActivity(), new String[]{WRITE_EXTERNAL_STORAGE,
Manifest.permission.CAMERA}, 1000);
}
btnGuardar.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {

}
});

Logcat message when button is pressed:
com.example.luvin.drawercero D/ViewRootImpl#6731d38[MainActivity]: ViewPostIme pointer 1
To complete my question, I have the permissions in the manifest. I already tried to call the camera in another way, tried creating the method in the MainActivity to create the OnClick event in the XML Layout, but nothing works.
If anyone knows how to solve this issue please help.
Thanks.

You forgot to add the on click listener to your photo button. This should solve your problem:
btnCamara = view.findViewById(R.id.tomarFoto);
btnCamera.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
tomarFoto(v);
}
});

Recycler's custom adapter methods are not called

i am using other layout elements and recyclerview in a layout and inflating cardview layout in oncreateViewHolder (custom adapter). Methods are only called when i just user recyclerview in a layout not with other layout elements.

Change inflated row in adapter on click

I have an adapter with buttons and text views. It represents friend requests.
TextView text would be : Do you want to accept X as your friend?
There are 2 buttons : one for accepting, one for declining. Pressing Decline, it would just remove the row from the ListView, while pressing accept will change the text into: X and Y are now friends.
My question is how can I get the position of the row and change it on button press and also save the View for next time I access it?
Adapter : At the moment I don't have proper data structure for the adapter, so for testing purposes, just using a String:
public class FriendRequestAdapter extends BaseAdapter {
String mName;
Context mContext;
public FriendRequestAdapter(String name, Context context) {
this.mName = name;
this.mContext = context;
}
#Override
public int getCount() {
return 1;
}
#Override
public Object getItem(int position) {
return null;
}
#Override
public long getItemId(int position) {
return 0;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
LayoutInflater mInflater = (LayoutInflater)
mContext.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
convertView = mInflater.inflate(R.layout.friend_request_layout, null);
}
TextView sender_name = (TextView) convertView.findViewById(R.id.wannabe_name);
if (mName.length() > 11) {
mName = mName.substring(0, 12);
}
sender_name.setText(mName);
ImageButton friend_request_accepted = (ImageButton) convertView.findViewById(R.id.accept_friend_request);
friend_request_accepted.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
new AsyncTask<Void, Void, Void>() {
#Override
protected Void doInBackground(Void... params) {
try {
new APIService().confirmInvite();
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
};
}
});
return convertView;
}

Custom ListView is not displayed

Following some tutorials, I managed to make a custom list.
But the whole screen is just a list
And now want to put the list below the form. And to make the whole screen make scroll along with the list (see the last item in the list, the form needs to rise)
The log (Toasty) says that the item was added, but nothing appears. I do not know if the problem is in how I add, or is the way I try to display

UPDATE
When I add an item in the list, nothing is shown. But after I click a TextEdit, and the virtual keyboard up, after typing some value, I close the keyboard, then the adapter.getView () is called and the list appears

I think I found your problem. Shouldn't the following code:
((ListView) findViewById(android.R.id.list)).setAdapter(listaAdapter);
Be:
((ListView) findViewById(R.id.list)).setAdapter(listaAdapter);
instead?
You are trying to find a default Android view, rather than the view that you have created, which means that you are not actually setting the adapter for your ListView.

I am not sure about that, but if you want the list to be scrollable with the activity, you should use ScrollView, and then check if you scroll the list or the view itself. Try it
You can also try to see with debugger if the item was actually added to the list. I hope you will find an error.

Found the solution
1) The adapter have 2 constructors, but just 1 with List<ItemVenda> itens, and it isn't called.
I fixed it.
2) To add an item on the list, I need to call adapter.add() and not adapter.getItens().add()`. I think this trigger others methods.
3) Finally, to take the scroll list, and apply the scroll across the screen, I need to increase the size of the list. Then I override the method adapter.add(), and calculate the new height of the list, and add android:scrollbars="none" on ListView
Thanks to all, especially to #Marek
