How can i setup a base drawer for all activities

I have read a lot of answers here but could not manage to do it. I want all of my activities to have a drawer. Inside the drawer i have a ListView which contains all of the activities that the drawer should open. This is the implementation of the drawer:
public abstract class DrawerActivity extends BaseActivity {
private DrawerLayout drawerLayout;
private ListView drawerList;
private ActionBarDrawerToggle drawerToggle;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.base_drawer_layout);
drawerLayout = findViewById(R.id.drawer_layout);
drawerList = findViewById(R.id.left_drawer);
final ArrayList<String> elements = new ArrayList<>();
elements.add("My tasks");
elements.add("Issues");
drawerList.setAdapter(new ArrayAdapter<>(this, android.R.layout.simple_list_item_1, elements));
drawerList.setOnItemClickListener(createOnDrawerItemClickListener());
// enable ActionBar app icon to behave as action to toggle nav drawer
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
// ActionBarDrawerToggle ties together the the proper interactions
// between the sliding drawer and the action bar app icon
drawerToggle = new ActionBarDrawerToggle(
this, /* host Activity */
drawerLayout, /* DrawerLayout object */
R.string.drawer_open, /* "open drawer" description for accessibility */
R.string.drawer_close /* "close drawer" description for accessibility */
) {
public void onDrawerClosed(View view)
{
getSupportActionBar().setTitle("TITLE");
invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
public void onDrawerOpened(View drawerView)
{
getSupportActionBar().setTitle("Title");
invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
};
drawerLayout.addDrawerListener(drawerToggle);
}
/**
* When using the ActionBarDrawerToggle, you must call it during
* onPostCreate() and onConfigurationChanged()...
*/
#Override
protected void onPostCreate(Bundle savedInstanceState)
{
super.onPostCreate(savedInstanceState);
// Sync the toggle state after onRestoreInstanceState has occurred.
drawerToggle.syncState();
}
#Override
public void onConfigurationChanged(Configuration newConfig)
{
super.onConfigurationChanged(newConfig);
// Pass any configuration change to the drawer toggles
drawerToggle.onConfigurationChanged(newConfig);
}
#Override
public boolean onOptionsItemSelected(MenuItem item)
{
if (drawerToggle.onOptionsItemSelected(item))
return true;
return super.onOptionsItemSelected(item);
}
protected abstract DrawerItemClickListener createOnDrawerItemClickListener();
protected ListView drawerList()
{
return drawerList;
}
protected DrawerLayout drawerLayout()
{
return drawerLayout;
}
}
This is the drawer layout xml file
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- The main content view -->
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<!-- The navigation drawer -->
<ListView
android:id="#+id/left_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:divider="#android:color/transparent"
android:dividerHeight="0dp"
android:background="#274"/>
</android.support.v4.widget.DrawerLayout>
Lets say i have currently two activities, My Tasks and Issues and both of them extend DrawerActivity. If i am in the Issues activity, how can i open the My Tasks activity through that drawer?
All activities that extend DrawerActivity implements createOnDrawerItemClickListener() which inside creates a new fragment with the layout of the the activity that implements DrawerActivity, which i'm pretty sure is wrong.
Example implementation:
#Override
protected DrawerItemClickListener createOnDrawerItemClickListener()
{
return new DrawerItemClickListener(position ->
{
FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction().replace(R.id.content_frame, new TaskFragment()).commit();
drawerList().setItemChecked(position, true);
drawerLayout().closeDrawer(drawerList());
});
}
And the DrawerItemClickListener:
public class DrawerItemClickListener implements ListView.OnItemClickListener {
private FragmentStrategy fragmentStrategy;
public DrawerItemClickListener(final FragmentStrategy fragmentStrategy)
{
this.fragmentStrategy = fragmentStrategy;
}
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id)
{
fragmentStrategy.showFragment(position);
}
public interface FragmentStrategy {
void showFragment(final int position);
}
}
How can i make this work?

In your case adding fragment will be the best solution.
create a fragment BlankFragment.java
public class BlankFragment extends Fragment {
public BlankFragment() {
// Required empty public constructor
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
return inflater.inflate(R.layout.fragment_blank, container, false);
}
}
and create fragment_black.xml
<FrameLayout 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"
tools:context="com.above_inc.shyam.drawer.BlankFragment">
<!-- TODO: Update blank fragment layout -->
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="#string/hello_blank_fragment" />
</FrameLayout>
now replace your method
public boolean onNavigationItemSelected(MenuItem item) {
// Handle navigation view item clicks here.
int id = item.getItemId();
Fragment fragment = null;
if (id == R.id.nav_camera) {
// Handle the camera action
fragment = new BlankFragment();
} else if (id == R.id.nav_gallery) {
} else if (id == R.id.nav_slideshow) {
} else if (id == R.id.nav_manage) {
} else if (id == R.id.nav_share) {
} else if (id == R.id.nav_send) {
}
if (fragment != null) {
FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager.beginTransaction()
.replace(R.id.frame_container, fragment).commit();
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
add below code in your content_main.xml
<?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: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.above_inc.shyam.drawer.MainActivity"
tools:showIn="#layout/app_bar_main">
<FrameLayout
android:id="#+id/frame_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
</RelativeLayout>
you can also add more fragment to other options same as camera in above code

problems with With Fragments and ViewPager

have view pager with 3section . want inside this pagers put fragment . and i use this example : http://www.truiton.com/2015/06/android-tabs-example-fragments-viewpager/
Main Activity :
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tab_layout);
tabLayout.addTab(tabLayout.newTab().setText("Tab 1"));
tabLayout.addTab(tabLayout.newTab().setText("Tab 2"));
tabLayout.addTab(tabLayout.newTab().setText("Tab 3"));
tabLayout.setTabGravity(TabLayout.GRAVITY_FILL);
final ViewPager viewPager = (ViewPager) findViewById(R.id.pager);
final PagerAdapter adapter = new PagerAdapter
(getSupportFragmentManager(), tabLayout.getTabCount());
viewPager.setAdapter(adapter);
viewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
tabLayout.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
#Override
public void onTabSelected(TabLayout.Tab tab) {
viewPager.setCurrentItem(tab.getPosition());
}
#Override
public void onTabUnselected(TabLayout.Tab tab) {
}
#Override
public void onTabReselected(TabLayout.Tab tab) {
}
});
}
#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);
}
}
XML:
<RelativeLayout
android:id="#+id/main_layout"
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:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:background="?attr/colorPrimary"
android:elevation="6dp"
android:minHeight="?attr/actionBarSize"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"/>
<android.support.design.widget.TabLayout
android:id="#+id/tab_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/toolbar"
android:background="?attr/colorPrimary"
android:elevation="6dp"
android:minHeight="?attr/actionBarSize"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"/>
<android.support.v4.view.ViewPager
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="fill_parent"
android:layout_below="#id/tab_layout"/>
</RelativeLayout>
TabFragment1 :
public class TabFragment1 extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.tab_fragment_1, container, false);
}
}
XML:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:id="#+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:text="Tab 1"
android:textAppearance="?android:attr/textAppearanceLarge"/>
</LinearLayout>
and 2more fragment class like this .
PagerAdapter :
public class PagerAdapter extends FragmentStatePagerAdapter {
int mNumOfTabs;
public PagerAdapter(FragmentManager fm, int NumOfTabs) {
super(fm);
this.mNumOfTabs = NumOfTabs;
}
#Override
public Fragment getItem(int position) {
switch (position) {
case 0:
TabFragment1 tab1 = new TabFragment1();
return tab1;
case 1:
TabFragment2 tab2 = new TabFragment2();
return tab2;
case 2:
TabFragment3 tab3 = new TabFragment3();
return tab3;
default:
return null;
}
}
#Override
public int getCount() {
return mNumOfTabs;
}
}
so i have error in pageradapter in line :
super(fm);
and this line : public Fragment getItem(int position) {
and another error in Main activity in line :
final PagerAdapter adapter = new PagerAdapter
(getSupportFragmentManager(), tabLayout.getTabCount());

You have to import the fragments from support.v4 library, you have to replace the imports for android.support.v4 like this.
import android.app.Fragment; > import android.support.v4.app.Fragment;
import android.app.FragmentManager; >importandroid.support.v4.app.FragmentManager;
import android.app.FragmentStatePagerAdapter; > import android.support.v4.app.FragmentStatePagerAdapter;

You need to create Custom ViewPager Class this way .
public class CustomViewPager extends ViewPager {
private boolean swipeable = false;
public CustomViewPager(Context context) {
super(context);
}
public CustomViewPager(Context context, AttributeSet attrs) {
super(context, attrs);
}
// Call this method in your motion events when you want to disable or enable
// It should work as desired.
public void setSwipeable(boolean swipeable) {
this.swipeable = swipeable;
}
#Override
public boolean onInterceptTouchEvent(MotionEvent arg0) {
return (this.swipeable) ? super.onInterceptTouchEvent(arg0) : false;
}
Now
CustomViewPager ViewPagerObj = (CustomViewPager)findViewById(R.id.container);
ViewPagerObj.setSwipeable(false);
You should add this in your XML
<Your_packagename.CustomViewPager
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />

The accepted answer does not work for me. Beginners can just use this kotlin file instead of the accepted answer java file.
class CustomViewPager: ViewPager {
private var swipeable = false
constructor(context: Context) : super(context)
constructor(context:Context, attrs: AttributeSet) : super(context, attrs)
fun setSwipeable(swipeable:Boolean) {
this.swipeable = swipeable
}
override fun onInterceptTouchEvent(arg0: MotionEvent):Boolean {
return if ((this.swipeable)) super.onInterceptTouchEvent(arg0) else false
}
override fun onTouchEvent(event:MotionEvent):Boolean {
return if (this.swipeable) super.onTouchEvent(event) else false
}
}

How to use Navigation Drawer without duplicate code?

I have created a Navigation Drawer following a tutorial, but now I have a problem. How can I use it in multiple activities without duplicating the code?
I tried extending the main activity, but I found some problems with Toolbar. There's some other way?
Thanks, this is my code.

Create a baseactivity with your drawer inside and then extend base activity to all activities in which you want drawer.
And instead of calling setcontentview() in oncreate inheriting activities use layout inflator

How to Display Navigation Drawer in all activities?

Here is part of real code from my project. #Bind is from awesome Butterknife library. AbstractToolbarActivity it's a sub class of the AppCompatActivity that follows the same logic (avoiding duplicating code of initializing toolbars)

Swipe Function control by ViewPager .Your Viewpager layout_height is 0dp in here That's why have problem .
So basically set this way
android:layout_width="match_parent"
android:layout_height="wrap_content"
