Toolbar Widget Android

Looking for a new toolbar widget, Then check this tutorial which will let develop the latest going on toolbar. Toolbar widget has beed introduced by google in 5.0 and now we are seeing this in most of the google apps like gmail , playstore etc.

so how to go about it =>


Structure of my app is going to be like this as shown in image  :



Rest you can go your way, what ever you like ..

1.1 Constants.java

package com.constants;

Working with tabs in Android using Fragments

Hey Guys,

Today i worked on tabs using fragments. And Always try to keep things simple as a like that        way.
 So here we go...
 
Since we have seen alots of examples which maintain fragment stacks manually using hashmaps  and all . But i've read this from stackoverflow and other reference web sites about           
 fragmenttabhost so going to use this.
And thats how it works.
Base Classes :

 1. AppMainTabActivity.java
    
public class AppTabBSecondFragment extends BaseFragment {

Button mBackbtn;
View mView;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
mView = inflater.inflate(R.layout.app_tab_b_second_screen, container,
false);
initializeWidgets();
return mView;
}

private void initializeWidgets() {
mBackbtn = (Button) mView.findViewById(R.id.backbtn);

mBackbtn.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View v) {

mActivity.handleBackPress();

}
});
}

}

2. BaseFragment.java

import android.content.Intent;
import android.os.Bundle;
import android.support.v4.app.Fragment;

public class BaseFragment extends Fragment {
public AppMainTabActivity mActivity;

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

mActivity = (AppMainTabActivity) this.getActivity();
}

public boolean onBackPressed() {
return false;
}

public void onActivityResult(int requestCode, int resultCode, Intent data) {

}
}


Fragments which we are going to add in tabs and replace now 

1. AppTabAFirstFragment.java


public class AppTabAFirstFragment extends BaseFragment {
    private Button mGotoButton;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View view       =   inflater.inflate(R.layout.app_tab_a_first_screen, container, false);

        mGotoButton =   (Button) view.findViewById(R.id.id_next_tab_a_button);
        mGotoButton.setOnClickListener(listener);

        return view;
    }

    private OnClickListener listener        =   new View.OnClickListener(){
        @Override
        public void onClick(View v){
            /* Go to next fragment in navigation stack*/
            mActivity.mAddFragments(AppConstants.TAB_A, new AppTabASecondFragment(),true,true);
        }
    };
}


2. AppTabASecondFragment.java

public class AppTabASecondFragment extends BaseFragment {

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
        View view    =  inflater.inflate(R.layout.app_tab_a_second_screen, container, false);
        return view;
}

}

3. AppTabBFirstFragment.java

public class AppTabBFirstFragment extends BaseFragment {

    private Button mGotoButton;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View view       =   inflater.inflate(R.layout.app_tab_b_first_screen, container, false);

        mGotoButton =   (Button) view.findViewById(R.id.id_next_tab_b_button);
        mGotoButton.setOnClickListener(listener);

        return view;
    }

    private OnClickListener listener        =   new View.OnClickListener(){
        @Override
        public void onClick(View v){
            /* Go to next fragment in navigation stack*/
            mActivity.mAddFragments(AppConstants.TAB_B, new AppTabBSecondFragment(),true,true);
        }
    };
}


4. AppTabBSecondFragment.java

public class AppTabBSecondFragment extends BaseFragment {

Button mBackbtn;
View mView;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
mView = inflater.inflate(R.layout.app_tab_b_second_screen, container,
false);
initializeWidgets();
return mView;
}

private void initializeWidgets() {
mBackbtn = (Button) mView.findViewById(R.id.backbtn);

mBackbtn.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View v) {

mActivity.handleBackPress();

}
});
}

}

5. AppTabCFirstFragment.java

public class AppTabCFirstFragment extends BaseFragment {

    private Button mGotoButton;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View view       =   inflater.inflate(R.layout.app_tab_c_first_screen, container, false);

        mGotoButton =   (Button) view.findViewById(R.id.id_next_tab_C_button);
        mGotoButton.setOnClickListener(listener);

        return view;
    }

    private OnClickListener listener   =  new View.OnClickListener(){
        @Override
        public void onClick(View v){
            /* Go to next fragment in navigation stack*/
            mActivity.mAddFragments(AppConstants.TAB_C, new AppTabCSecondFragment(),true,true);
        }
    };
}


6. AppTabCSecondFragment.java

public class AppTabCSecondFragment extends BaseFragment {
Button mBackbtn;
View mView; 
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
mView = inflater.inflate(R.layout.app_tab_c_second_screen,
container, false);
initializeWidgets();
return mView;
}

private void initializeWidgets() {
mBackbtn=(Button)mView.findViewById(R.id.backbtn);
mBackbtn.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {

mActivity.handleBackPress();
}
});

}
}


Now interface that i used to handle backpress normally :

1. BackButtonCallback.java

public interface BackButtonCallback {

void handleBackPress();
}


Now the constants class for this ....


1. AppConstants.java

public class AppConstants {
public static final String TAB_A = "tab_a_identifier";
public static final String TAB_B = "tab_b_identifier";
public static final String TAB_C = "tab_c_identifier";

}


And finally the XML layouts :
