Would like to know how to create a NavigationDrawer within a Fragment (in this case my HomeFragment) and NOT in an Activity. Have seen everything on how to create a NavigationDrawer within an Activity, such as MainActivity, but my goal for this project is to create a NavigationDrawer ONLY for the HomeFragment. Don't want any of the other fragments to contain it. The drawer_menu will contain Edit Profile, Settings, and Log Out. Below I have posted what I have done... Is there a better way to do it? Code seems to be a bit awkward.
Every video I have seen, every post has been about creating a NavigationDrawer in Activities, so I'm wondering what the code would look like for Fragment. I tried doing it just like you would for Activity, but it wouldn't work.
Below you guys have my HomeFragment.java and fragment_home.xml

It's not possible.
Because To implement the Navigation Drawer we first need to add android.support.v4.widget.DrawerLayout as the root of the activity layout.
For Toggle Option of Navigation Drawer, We Require ToolBar.
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(this, drawerLayout, toolbar,
R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawerLayout.addDrawerListener(toggle);
The ToolBar is not possible in the fragment.
For Better use, Make Navigation View in Activity inside the DrawerLayout.
I am using a custom adapter for my ListView which I already don't understand as much as I would like to. I can find information online on how to add a row to ListView but it doesn't integrate nicely into my code, I'm guessing because I'm using a custom adapter. I have my setOnClickListener() method for my button in my Main Activity and have been experimenting there but just cant figure it out I'm also not sure if my method is in the right place?
this is the mainActivity
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.app.Activity;
import android.view.View;
import android.widget.AdapterView;

public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final String[] Chores = {""};
ListAdapter MyAdapter = new CustomAdapter(this, Chores);
ListView listViewObject = (ListView)findViewById(R.id.customListView_ID);
listViewObject.setAdapter(MyAdapter);
listViewObject.setOnItemClickListener(
new AdapterView.OnItemClickListener(){
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id){
String ChoreString = String.valueOf(parent.getItemAtPosition(position));
}
}
);
// this is where I am trying to have button click add another row to my listView
final Button button = (Button) findViewById(R.id.button_ID);
button.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
//this is where I am stuck
}
});
}
}
here is my CustomAdapter class

First make your list into an ArrayList instead of String array.
private ArrayList<String> arrayList;
In the buttons onClick
arrayList.add("New Item");
((ArrayAdapter)MyAdapter).notifyDataSetChanged();
public void onClick(View v) {
String stringToAdd = ... //
MyAdapter.add(stringToAdd);
}
You will need to add final to the adapter declaration for this to work:
final ListAdapter MyAdapter = new CustomAdapter(this, Chores);
EDIT
To add more than one row at a time:
public void onClick(View v) {
String[] rowsToAdd = ... //
MyAdapter.addAll(rowsToAdd);
}
How can I add fragments for each tab in BottomBar in Android studio please a good example like list view or grid view for each tab..thanks
You need to implement SetOnTabSelectListerner.
bottomBar.setOnTabSelectListener(new OnTabSelectListener() {
#Override
public void onTabSelected(#IdRes int tabId) {
Fragment fragment = null;
Class fragmentClass = null;
switch (tabId) {
case R.id.tab_one:
fragmentClass = TabOneFragment.class;
break;
case R.id.tab_two:
fragmentClass = TabTwoFragment.class;
break;
case R.id.tab_three:
fragmentClass = TabThreeFragment.class;
break;
case R.id.tab_four:
fragmentClass = TabFourFragment.class;
break;
}
try {
fragment = (Fragment) fragmentClass.newInstance();
} catch (Exception e) {
e.printStackTrace();
}
FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager.beginTransaction().replace(R.id.flContent, fragment).commit();
}
});

<item>A Fragment represents a behavior or a portion of user interface in an Activity. You can combine multiple fragments in a single activity to build a multi-pane UI and reuse a fragment in multiple activities. You can think of a fragment as a modular section of an activity, which has its own lifecycle, receives its own input events, and which you can add or remove while the activity is running (sort of like a "sub activity" that you can reuse in different activities).</item>
<item>Activities are one of the fundamental building blocks of apps on the Android platform. They serve as the entry point for a user's interaction with an app, and are also central to how a user navigates within an app (as with the Back button) or between apps (as with the Recents button). </item>
<item>A Service is an application component that can perform long-running operations in the background, and it does not provide a user interface. Another application component can start a service, and it continues to run in the background even if the user switches to another application. Additionally, a component can bind to a service to interact with it and even perform interprocess communication (IPC). For example, a service can handle network transactions, play music, perform file I/O, or interact with a content provider, all from the background.</item>
<item>Content providers can help an application manage access to data stored by itself, stored by other apps, and provide a way to share data with other apps. They encapsulate the data, and provide mechanisms for defining data security. Content providers are the standard interface that connects data in one process with code running in another process. Implementing a content provider has many advantages. </item>

I use a FrameLayout as a custom list item. I have an onItemClickListener set up to the listView but my items each have a button within themselves, and while the button in them is clickable, the item itself is not and they're supposed to do different things. How do I make the item as well as the button within it both clickable?
Here's the code:
import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.ListAdapter;
import android.widget.ListView;
import android.widget.TextView;
import java.util.ArrayList;
public class ProjectCreateScreen extends ActionBarActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.secondary_layout1);
final TextView noProject = (TextView) findViewById(R.id.NOPROJECT);
Button btn = (Button) findViewById(R.id.addBtn);
final ArrayList<String> listItems=new ArrayList<String>();
final ListAdapter addAdapter = new ArrayAdapter<String>(this,
R.layout.list_item, R.id.listFrame, listItems);
final ListView lv = (ListView) findViewById(R.id.lv);
lv.setAdapter(addAdapter);
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
noProject.setVisibility(View.GONE);
lv.setVisibility(View.VISIBLE);
listItems.add("New Project");
((ArrayAdapter) addAdapter).notifyDataSetChanged();
}
});
lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Intent switchToEdit = new Intent(ProjectCreateScreen.this,
teamCreateScreen.class);
startActivity(switchToEdit);
}
});
}
#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();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
The custom listView item xml:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<TextView
android:id="#+id/listFrame"
android:layout_width="wrap_content"
android:layout_height="80dp"
android:textSize="20sp"
/>
<Button android:id="#+id/frameBtn"
android:layout_width="30dp"
android:layout_height="30dp"
android:layout_gravity="top|right"
/>
</FrameLayout>
The xml of the activity:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/rl">
<Button
android:layout_width="wrap_content"
android:layout_height="60dp"
android:text="#string/AddProject"
android:id="#+id/addBtn"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true" />
<TextView
android:layout_width="200dp"
android:layout_height="wrap_content"
android:text="#string/noProjectsNotice"
android:id="#+id/NOPROJECT"
android:gravity="center"
android:layout_centerVertical="true"
android:layout_centerHorizontal="true"
android:textSize="16sp"/>
<ListView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/addBtn"
android:id="#+id/lv"
android:visibility="invisible">
</ListView>
</RelativeLayout>
Add the following two attributes for any view you want to be clickable inside the listview:
android:focusable="false"
android:focusableInTouchMode="false"
That should solve most cases. If that is not enough, also add the following attribute to the root layout of your list view layout
android:descendantFocusability="blocksDescendants"
I would like to ask how to add a menu(three points with options like the actionBar has) to a grid view item? I need it to look similar to youtube's mobile application videos: they all have these three points with a couple of options inside of them. How can I achieve this?
Here's the code:
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.GridView;
import android.widget.ListAdapter;
import java.util.ArrayList;
public class teamTasks extends Activity{
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.team_individual_tasks);
Button btn3 = (Button) findViewById(R.id.addTasks);
final ArrayList<String> listItemsTasks=new ArrayList<String>();
final ListAdapter addAdapterTasks = new ArrayAdapter<String>(this, R.layout.custom_box,
R.id.customBox, listItemsTasks);
GridView gvtask = (GridView) findViewById(R.id.gvTasks);
gvtask.setAdapter(addAdapterTasks);
btn3.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
listItemsTasks.add("New Task");
}
});
gvtask.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
}
});
}
}
The layout:
<?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">
<Button
android:layout_width="60dp"
android:layout_height="60dp"
android:text="+"
android:textSize="20sp"
android:id="#+id/addTasks"/>
<GridView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/addTasks"
android:id="#+id/gvTasks"
android:numColumns="2">
</GridView>
</RelativeLayout>
Custom gridView item:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:layout_width="wrap_content"
android:layout_height="120dp"
android:id="#+id/customBox"/>
