I'm setting up a bottom navigation for my app. I want to set/customize the actions for the menus but I'm facing an issue in the code. It can not find the id 'bottomNavView_bar' of the bottomnavigationview. I'm getting the error "Can't resolve symbol 'bottomNavView_bar'"
Here is my activity_main.xml

Select tools>-android>-SDK manager
and download the SDK build tools, SDK platform and Google API's( the Google API stores packages such as "import android.view.Menu" etc.) for the target SDK version of your project(20 as shown in your screenshot). if you are not sure which items you have to download, you can select all of them. (will take more time to download of course).
Restart the IDE

I just included an options menu in my app, but in one of my activities it seems to create a white empty space- can anyone tell me why??
It work in other activities in the same app, but not this single activity.
I Hope anyone can help :-)
public class GifsActivity extends OptionsMenu {
private Toolbar toolbar;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_gifs);
toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
ImageView gifImageView = (ImageView) findViewById(R.id.iv_gif);
Glide.with(this)
.load("http://i.imgur.com/Vth6CBz.gif")
.asBitmap()
.placeholder(R.drawable.ic_cloud_off_red)
.error(R.drawable.ic_cloud_off_red)
.into(gifImageView);
}
}

Remove android:gravity="center_vertical" from your layout. Then your layout will be as below:
<?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"

android:layout_width="match_parent"/>
<ImageView
android:layout_below="#id/include"
android:id="#+id/iv_gif"
android:layout_width="match_parent"

Please comment if you have any doubts.
Do not use android.R.layout.simple_list_item_1 and create you own layout file. This android.R.layout.simple_list_item_1 layout file has a simple text view but the text color is something related to white that's why you cant see it. Now you have to create a new layout file which contain only text view and set text color and pass it to your adapter
Try this.
<ListView
android:background="#drawable/alphabit_bg"
android:id="#+id/alphabitorder"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="2"
android:scrollbars="none"/>
<ListView
android:id="#+id/itemcontent"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="8"/>
</LinearLayout>
So, I want to build an app that has only one activity and will use multiple fragments. I have a log in activity, and after I make the log in I go to my maintactivity that has a fragment and a view-pager so I can swipe through some fragments(this fragments will be like a day of a calendar). My navigation drawer will be used to open other fragments, no the same as the ones mentioned before. My issues are, after I apply the view-pager, my button to open the drawer doesn't work and my fragments doesn't change when I click in the navigation drawer items, is keeps the fragment on top (I open it with the slide movement, since the button doesn't work). Here is my code:

You don't have to write your own code for this.
here is a nice library for your problem with all required things.

I tried various solution to get toolbar title but none of them worked. like using and others. What went wrong with my code. can you advice. I m getting menu and their options but Title of toolbar no luck.
getSupportActionBar().setDisplayShowTitleEnabled(true);
getSupportActionBar().setTitle("Hello");
Below is my style.xml code:
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">

You can set title to toolbar for reference no need to get toolbar of support.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
toolbar.setTitle("Hello");
setSupportActionBar(toolbar);
}

This is my first android app and I'm trying to add the Actionbar at the top but i cant seem to get it to work. All I get is a Blank blue bar across the top with no title and no overflow menu. To create this i used the instructions found here http://developer.android.com/training/appbar/index.html but even following the instructions to a T it doesn't seem to work. Even though I am not getting a compile error i was wondering if i was doing something wrong?
MainActivity.java
package com.caseybowman.studdybuddy;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.RelativeLayout;
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar myToolbar = (Toolbar) findViewById(R.id.my_toolbar);
setSupportActionBar(myToolbar);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
RelativeLayout main_view = (RelativeLayout) findViewById(R.id.Semesters);
switch(item.getItemId()){
case R.id.add:
//do something
return true;
case R.id.edit:
return true;
case R.id.settings:
return true;
default:
return super.onOptionsItemSelected(item);
}
}
}

Try to add this code
getSupportActionBar().setTitle("Your Title");
Or you can customize your toolbar by defining one TextView inside the toolbar and assign your title like this.
<android.support.v7.widget.Toolbar
android:id="#+id/my_toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
android:elevation="4dp"
android:theme="#style/ThemeOverlay.AppCompat.ActionBar"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Your Title"/>
</android.support.v7.widget.Toolbar>
Try this
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/main_content"

<android.support.design.widget.AppBarLayout
