I am currently working on a simple android application.
There is a login page, and as it is possible to login as a Driver or as a Passenger, there are different tabs in that page.
I have to use the same "email" and "password fields a, and the same login button. basically the only thing that change is the subtitle
I need to figure out which tab is active when the login button is pressed, in order to use the right login options and send the user to the right place.
Here are parts of the code:

The pageAdapter class
public class PageAdapter extends FragmentPagerAdapter {
private Context context;
public PageAdapter(FragmentManager fm, Context context) {
super(fm);
this.context=context;
}
public Fragment getItem(int pos) {
switch (pos) {
case 0:
return new LoginDriver();
case 1:
return new LoginPassenger();
}
return null;
}
public int getCount() {
return 2;
}
public CharSequence getPageTitle(int pos) {
switch (pos) {
case 0:
return context.getApplicationContext().getResources().getString(R.string.Driver);
case 1:
return context.getApplicationContext().getResources().getString(R.string.Passenger);
}
return null;
}
}
And from the LoginScreen class, I need to find out the current tab in this event
public void onConnexion(View view) {
android.content.Intent getNextScreen;
String mail = txtMail.getText().toString();
String pass = txtPass.getText().toString();
//Identification(this.)
getNextScreen = new android.content.Intent(this, Summary_Driver_Screen.class);
startActivity(getNextScreen);
}
Thank you very much for your help. I can give more details if needed.
getSelectedTabPosition() does exactly what you need: returning the current index of the selected tab.

#Override
public void onClick(View v) {
if(map.getMapType() == GoogleMap.MAP_TYPE_NORMAL || map.getMapType() == GoogleMap.MAP_TYPE_HYBRID){
map.setTrafficEnabled(true);
maptrafic.setImageResource(R.drawable.trafficmap_on);
}
else {
map.setTrafficEnabled(false);
maptrafic.setImageResource(R.drawable.trafficmap_off);
map.setMapType(GoogleMap.MAP_TYPE_NORMAL);
}
}

if you have any idea please don't ready only i need help. any idea are welcome.
if you need more details juste ask i am online 24/7 each second.
I've got a NestedScrollView inside of a ScrollView because I have an Activity with three hidden fragments that contain text, and when you click one of the fragments it opens to reveal the text. But the thing is that there is quite a bit of text so I'm using NestedScrollView so the reader can read all of it, and the first time it works fine (text doesn't overlap), and then second time when I close the fragment and re-open it the text starts overlapping...
So as mentioned, first time it doesn't happen, and then I close the fragment and reopen it and this happens:
So why is this happening and how can I fix it?

You are getting the fragment overlapped because there is a new fragment added each time.
You simply need to do a check if the fragment exits already then there is no need to add a new fragment. You can assign a 'tag' when adding fragment. Code as follows-
if (fragmentManager.findFragmentByTag("First Fragment") == null)
fragmentManager.beginTransaction().add(R.id.fragment, new FirstFragment(), "First Fragment").commit();
OR
Rather then using .add() method use .replace() to make sure fragment got replaced each time.
According to your Activity code, you need to choose the correct way, but make sure there is no fragment getting re-created without destroying previous one.
Happy Coding !!
You are adding two fragments on top of each other.
Instead of add use replace when executing the fragment transaction:
From:
getSupportFragmentManager().beginTransaction().add(R.id.container_privacy, new PrivacyFragment(), null).addToBackStack(null).commit();
if (mPrivacyContainer.getVisibility() == View.GONE) {
mPrivacyContainer.setVisibility(View.VISIBLE);
} else {
mPrivacyContainer.setVisibility(View.GONE);
}
To:
getSupportFragmentManager().beginTransaction().replace(R.id.container_privacy, new PrivacyFragment(), null).addToBackStack(null).commit();
if (mPrivacyContainer.getVisibility() == View.GONE) {
mPrivacyContainer.setVisibility(View.VISIBLE);
} else {
mPrivacyContainer.setVisibility(View.GONE);

I'm making a football league app, and i need to show the classification.
I'm trying to show a header that indicates what represents each field and a listview with the teams below.
I'm using a SimpleCursorAdapter to fill the list, but if the values have a different number of digits the list is misaligned. ¿How can i align it or at least add a 0 before the one-digit numbers with the adapter?
The soure code of the fragment and the xml:
ClassificacioFragment.java:
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
String[] from = { EquipsContract.EquipEntry.COLUMN_NAME_NOM,
EquipsContract.EquipEntry.COLUMN_NAME_VICTORIES, EquipsContract.EquipEntry.COLUMN_NAME_DERROTES,
EquipsContract.EquipEntry.COLUMN_NAME_EMPATS, EquipsContract.EquipEntry.COLUMN_NAME_PUNTS};
int[] to = {R.id.item_nom, R.id.item_victories, R.id.item_derrotes, R.id.item_empats, R.id.item_punts};
View rootview = inflater.inflate(R.layout.fragment_classificacio, container, false);
ListView listView = (ListView) rootview.findViewById(R.id.classificacio);
listView.invalidateViews();
SimpleCursorAdapter adapter = new SimpleCursorAdapter(rootview.getContext(), R.layout.equip_row,
DBHandler.getDbInstance(getContext()).cursorClassificacio(), from, to);
listView.setAdapter(adapter);
String size = Integer.toString(DBHandler.getDbInstance(getContext()).getAllEquips().size());
Toast toast = Toast.makeText(getContext(), size, Toast.LENGTH_LONG);
toast.show();
return rootview;
}

And this is the result:
thanks.
You can simplify your ListView Row to use LinearLayout with weight parameters. It's more efficient and prevents issues with TextView's floating width.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal"
android:weightSum="9">
<TextView
android:id="#+id/item_nom"
android:layout_width="0dp"
android:layout_height="?android:attr/listPreferredItemHeight"
android:gravity="center_vertical"
android:textSize="20sp"
android:padding="2dp"
android:layout_marginStart="10dp"
android:layout_weight="4"
android:text="F.C. Barcelona"/>
<TextView
android:layout_width="0dp"
android:layout_height="?android:attr/listPreferredItemHeight"
android:layout_weight="1"
android:id="#+id/item_victories"
android:textSize="15sp"
android:text="10"
android:gravity="center"/>
<TextView
android:layout_width="0dp"
android:layout_height="?android:attr/listPreferredItemHeight"
android:layout_weight="1"
android:id="#+id/item_derrotes"
android:textSize="15sp"
android:text="20"
android:gravity="center"/>
<TextView
android:layout_width="0dp"
android:layout_height="?android:attr/listPreferredItemHeight"
android:layout_weight="1"
android:id="#+id/item_empats"
android:textSize="15sp"
android:text="30"
android:gravity="center"/>
<TextView
android:layout_height="?android:attr/listPreferredItemHeight"
android:layout_width="0dp"
android:layout_weight="2"
android:id="#+id/item_punts"
android:textSize="18sp"
android:text="40"
android:gravity="center"/>
</LinearLayout>
At first all of your text in the TextView must be center aligned.
android:gravity="center"
Then, pogramatically you should find the largest TextView and set the width of each other TextView in that row.
Or you use TableLayout ;)
Create a function for appending 0 with numbers less than 10.
public String appendZero(int input) {
if (input >= 10) {
return String.valueOf(input);
} else {
return "0" + String.valueOf(input);
}
}
While setting the text, call like this :
item_victories.setText(appendZero(victory_count.get(position)));
Hope this one will works for you.
