Creating multiple button counters in ListView in TabActivity

Creating multiple button counters in ListView in TabActivity - android

I'm trying to make an app to keep score during a game of golf. To do this I have 18 tabs in a tab activity (one for each hole) and then in each tab I have a ListView with a list of players, their score for the hole, and a plus and minus button.
I need to make it so that hitting the plus button in a row increases that players score for that hole but I'm having trouble figuring out where and how to do an OnClickListener and how to handle the indexing for the player and the hole.
I'm very new to Android Studio so any help is greatly appreciated!

Dynamic Fragment with CardView in a RecycleViewAdapter

I am totally new in the world of Android development and have some trouble to understand how a RecycleViewAdapter works with a CardView when the CardView is a Fragment. I was trying to understand the example on https://github.com/firebase/quickstart-android/blob/master/database/README.md but since they are using a lot of stuff which is related to Firebase I tried to port this to my own example.
I want to have a list which contains several cards just like this:
However, the user should be able to add and remove different cards. At the beginning the view should be empty and if the user press the floating button on the right corner
a new card should be created.
I've just ported the way I thought it should work. Unfortunately, when I press the button nothing is happening (of course the Hello World is printed).
Thanks for you help.
Here is the code of my MainActivity:
package com.example.dynamicfragment;
import android.app.FragmentManager;
import android.app.FragmentTransaction;
import android.os.Bundle;
import android.support.design.widget.FloatingActionButton;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
public class MainActivity extends AppCompatActivity
{
private FragmentManager fragmentManager;
private FragmentTransaction fragmentTransaction;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
fragmentManager = getFragmentManager();
fragmentTransaction = fragmentManager.beginTransaction();
Toolbar toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
FloatingActionButton fab = findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
System.out.println("Hello World");
fragmentTransaction.add(new CardListFragment(), "CardListFragment");
}
});
fragmentTransaction.commit();
}
#Override
public boolean onCreateOptionsMenu(Menu menu)
{
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item)
{
int id = item.getItemId();
if (id == R.id.action_settings)
{
return true;
}
return super.onOptionsItemSelected(item);
}
}
This is the class who extend the CardListFragment:

#Christoph M. The Fragment Transaction if you want to applu on ui u need to give a FrameLayout Id.
Create a FrameLayout with one id in your main class then attach your fragment to id value
like this below
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_activity);
FirstFragment fragment = new FirstFragment();
FragmentTransaction transaction =
getSupportFragmentManager().beginTransaction();
transaction.replace(R.id.frame_layout, fragment);
transaction.addToBackStack(ConstantVariables.FirstFragment);
transaction.commit();
}
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<FrameLayout
android:id="#+id/frame_layout"
android:layout_width="match_parent"
android:layout_height="match_parent" />

I've solved this by wrapping my button inside a LinearLayout.
Probable cause of the issue: It seems Button has higher z-index rendering when it comes to android and thus not wrapping it inside another layout renders the button higher than all other fragments.
<LinearLayout
android:id="#+id/register_btn_wrapper"
android:orientation="vertical"
android:layout_below="#+id/splash_logo_img"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<Button
android:id="#+id/register_btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/register"
android:textSize="#dimen/text_big"
android:paddingLeft="#dimen/btn_padding"
android:paddingStart="#dimen/btn_padding"
android:paddingRight="#dimen/btn_padding"
android:paddingEnd="#dimen/btn_padding"
android:layout_gravity="center"
android:background="#color/app_color" />
</LinearLayout>
Hope this helps.

When you bind your view in fragment it is always a better approach to bind it in the method
onViewCreated()
When you bind your view in onCreateView() you will face rendering issues.
So bind your view in onViewCreated() method and the problem should be solved
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.name_of_layout,container,false);
}
public void onViewCreated(View view, #Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
//bind your view here
}

In the onCreateView of the fragment try adding this line
View view = inflater.inflate(R.layout.fragment_name, container, false);
view.setBackgroundColor(Color.WHITE);
I had a similar issue and fixed it using the above lines. Also, don't forget to add android:clickable="true" to your fragment_layout.xml parent layout.

I couldn't find the reason for this issue though but here is a small workaround:
Update the below layouts and try:
Activity xml :
Added a Framelayout:
<FrameLayout
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<include layout="#layout/content_main"/>
</FrameLayout>
And in MainActivity: Used Framelayout container
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
CreateReportFragment fragment = CreateReportFragment.newInstance();
FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
transaction.replace(**R.id.container**, fragment, "CreateFragment");
transaction.addToBackStack("CreateBackStack");
transaction.commit();
}
});
In Content.xml Added android:layout_marginTop
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/content_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
android:layout_marginTop="?attr/actionBarSize"
tools:context="com.example.deep_kulshreshtha.toddsyndrome.MainActivity"
tools:showIn="#layout/activity_main">
In fragment_create_report.xml added android:layout_marginTop
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="?attr/actionBarSize"
android:background="#android:color/white">

I'm not sure if you still need help with this. But basically the fragment and the activity have to be in different layouts.
This is the general structure for it: (you don't have to use the specific layouts I user below)
<RelativeLayout>
<LinearLayout id="#+id/all_code_relevant_to_activity"></LinearLayout>
<LinearLayout
android:id="#+id/fragment_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
</LinearLayout>
</RelativeLayout>
Basically you want to have your fragment separate from the rest of the code. So basically you could make a <FrameLayout> around your code in Activity.xml and then add your fragment layout by itself inside the <FrameLayout> but outside <android.support.design.widget.CoordinatorLayout>. Or make two sub layouts the split them apart

It's so wired to show only SUBMIT button on the top of page. I want to suggest you to add fragment instead of replace. please let me know the result after this.
FragmentTransaction fragmentTransaction = activity.getSupportFragmentManager().beginTransaction();
fragmentTransaction.add(R.id.content_main, fragment, "SearchFragment");
fragmentTransaction.addToBackStack("SearchFragment");
fragmentTransaction.commitAllowingStateLoss();

In your activity xml, add one more element, FrameLayout to host the fragment, like below
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/content_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
tools:context="com.example.deep_kulshreshtha.toddsyndrome.MainActivity"
tools:showIn="#layout/activity_main">
<TextView
android:id="#+id/headline"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:textSize="32dp"
android:fontFamily="cursive"
android:text="#string/todd_syndrome" />
<!-- <android.support.design.widget.TextInputLayout
android:id="#+id/layout_last_name"
android:layout_below="#id/headline"
android:layout_centerHorizontal="true"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.design.widget.TextInputEditText
android:id="#+id/lastNameEditText"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="#string/edit_text_hint" />
</android.support.design.widget.TextInputLayout>-->
<EditText
android:id="#+id/editText"
android:layout_below="#id/headline"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="#string/edit_text_hint"/>
<Button
android:id="#+id/submitButton"
android:layout_centerHorizontal="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/submit"
android:layout_below="#id/editText"
android:onClick="viewPatientReport"/>
<!-- new layout to host fragment -->
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/fragment_holder"/>
</RelativeLayout>
and add your Fragment to that FrameLayout using.

set button property android:translationZ="-3dp" it will work.

What helped me is to add android:translationZ="10dp" to the layout that above the Buttons

fragment doesn't inflate right

I got a fragment that get the data in runtime and I think that what cause the problem, but I'm not sure.
it show the button twice and I cant scroll. if i'm writing false insted of true in View v = inflater.inflate(R.layout.fragment_book_view, container, true);
it shows only the button.
the fragment load in runtime in to FrameLayout at the activity, that layout suppose to contain diffrent fragment each time.
my fragment code:

Try to change
return inflater.inflate(R.layout.fragment_book_view, container, false) ;
to
return v;

change the first line third parameter to false,and as Lauren.Liuling said neen to change the last line to return v;.
