I am new to android, I am trying to open URL image on my main screen. My problem is that I am using navigation drawer also on my main page. Everything works fine only my main image which is coming from database is going slightly upwards, whereas the example which I copied in that the image is looking perfectly.
I don't know why my image is going upwards. The image should render like this :
My image is rendering like this:

I tried doing debugging but then also no use, it's so weird problem.
The problem occur for main_content xml . your image is cut off when you use it in you main_activity xml . Use this trick it will work . Simple put margin above your main_content xml

You have to include a custom action bar in your layout.
Please follow this link. It is explained very nicely with the code snaps and in depth. :)
In MainAcitivity you should extends Activity no an AppCompatActivity. AppCompatActivity show a bar

I have a problem within my code that seems to me as it is working but only in the given situation where On_Click Events within fragments are firing when using tab and enter key but not mouse click. I am using the emulator through android studio SDK23 for the emulater. When I test it on my phone sdk26 it does not allow the tap to click anything within the fragment. I feel like I may be missing something very simple.
Here is my Activity:

Ultimately I fixed my own problem. Which was started by choosing Navigation Activity when first starting my project.
I removed
<include layout="#layout/nav_menu_main" />
from my activity_main.xml then restructured it whith the xml from nav_menu_main, using DrawerLayout as the Parent and CoordinatorLayout from activity_main.xml as the child.
I consulted this stack Overflow which lead me to my fix.

I'm using default Navigation Drawer in Android Studio, and I added two fragments for first two button in navigation drawer. Everything works fine and I can switch between these fragments from drawer menu.
But I want to have a simple button in first fragment that clicking on it take me to second fragment. Clicking on such button opens second fragment but it seems to overlap whole screen and disappear the navigation view.

I've not changed other Java or XML codes.
Add a public method to MainActivity, cast getActivity() to MainActivity in your fragment, and then you can invoke the method. You can also use interface, refer Communicating with Other Fragments

In onNavigationItemSelected method do not create the DrawerLayout again. Simply call the closeDrawer.
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout); --> remove this line of code
drawer.closeDrawer(GravityCompat.START);
UPDATE
In your onCreate method change this line of code
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
to
drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
and add this line of code
DrawerLayout drawer
below this line of code
ViewPager mViewPager;
and remove the indicated line of code in onNavigationItemSelected method
if (id == R.id.home) {
fragmentManager.beginTransaction().replace(R.id.content_frame,new HomeFragment()).commit();
} else if (id == R.id.announcement) {
fragmentManager.beginTransaction().replace(R.id.content_frame,new AnnouncementFragment()).commit();
update above code as below :
if (id == R.id.home) {
fragmentManager.beginTransaction().replace(R.id.content_frame,new HomeFragment()).addToBackStack(null).commit();
} else if (id == R.id.announcement) {
fragmentManager.beginTransaction().replace(R.id.content_frame,new AnnouncementFragment()).addToBackStack(null).commit();
I've created a new Android Studio Project and my MainActivity is a Navigation Drawer Activity.
So, I can't show up fragments. I've read many post on internet and here too.

I open navigation drawer, select menu "Podcast".
PodcastsFragment should be shown, but it still showing activity.

Make the drawer's list in Your activity and add setOnItemClickListener().When the user selects an item in the drawer's list, the system calls onItemClick() on the OnItemClickListener given to setOnItemClickListener().
What you do in the onItemClick() method depends on how you've implemented your app structure. In the following example, selecting each item in the list inserts a different Fragment into the main content view (the FrameLayout element identified by the R.id.content_frame ID):
for more delail please read these articles youtube and github example
Latest - If you use Navigation Architecture Component, then you don't have to manually connect your fragments to your drawer MenuItem. The system will automatically tie you MenuItem to specific fragment If the id of the MenuItem in your menu/xyz_menu.xml matches the id of the destination in navigation/xyz_nav.xml, the NavController can then navigate to that destination.
Follow the correct steps mentioned in the official documentation : https://developer.android.com/guide/navigation/navigation-ui#Tie-navdrawer
Note :
They have a sample app linked to the same article which you can refer.
To get this is effect, do not implement onNavigationItemSelected otherwise it will override the system let you handle the navigation.
I created a menu with 5 items in a navigation drawer, the 5 items represent 5 different fragments, each time an item gets clicked it should show the related fragment.
Another click on a different item, fragment should be replaced and so on.
I created 5 seperate classes for the fragments.
When i start the app and click an item the very first time, the related fragment gets shown but after i click another item in the menu nothing happens (the fragment gets not replaced), i also get no errors and the app does not crash.
I don`t know where the problem is hopefully somebody can help, here is my code:

Example of 1 class (in this case Android):
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
public class Fragment_Android extends Fragment {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View fragandroid = inflater.inflate(R.layout.layout_android, null);
return fragandroid;
}
#Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
}
}
Example of 1 fragment xml (Android fragment):
<?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">
<TextView
android:id="#+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Android"
android:textAppearance="?android:attr/textAppearanceLarge"
android:layout_centerVertical="true"
android:layout_centerHorizontal="true" />
</RelativeLayout>
My main activity xml:
<LinearLayout 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:orientation="vertical"
tools:context="android.kadas.org.teka.MainActivity">
<include
android:id="#+id/my_toolbar"
layout="#layout/app_bar" />
<android.support.v4.widget.DrawerLayout
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<FrameLayout
android:id="#+id/fragment_container"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<fragment
android:id="#+id/fragment_navigation_drawer"
android:name="android.kadas.org.teka.NavigationDrawerFragment"
android:layout_width="#dimen/nav_drawer_width"
android:layout_height="match_parent"
android:layout_gravity="start"
app:layout="#layout/fragment_navigation_drawer"
tools:layout="#layout/fragment_navigation_drawer" />
</android.support.v4.widget.DrawerLayout>
</LinearLayout>
In the click listener you are actually replacing the entire layout of the activity with the desired fragment.
In your main activity's xml add the following layout, inside the RelativeLayout:
<FrameLayout
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent" />
Change your
fragtrans.replace(R.id.drawer_layout, fragmentX);
statements to
fragtrans.replace(R.id.container, fragmentX);
Finally solved due to the big help of Alexandru Rosianu.
The code has been amended with the correct one.
