Sunshine Project Exercise
Sunshine Project
https://github.com/udacity/ud851-Sunshine
Toys Project
https://github.com/udacity/ud851-Exercises

Flow
1. Impot.ExerciseProject();
2. Shift*2 (TODO);
3. for (i=0; i<TODO.size();i++){TODO.execute();}
4. while (!Succed){try();}
5. Import.NextExerciseProject

LESSON 1
Make Sunshine Project

Add an ID
@ sebagai pembeda bahwa itu bukan String, tapi untuk
mencari/menambahkan isi di dalam Resource
+ sebagai tanda bahwa untuk menambahkan id baru, bukan
untuk mencari
tv_tv_names : nama id dalam bentuk Snake Case

Make array of String
1. Create New JavaClass “ToyBox.java”
2. public static String[] getToyNames() {
return new String[] {
"Tazos",
“...........”
};
}
3. Panggil dalam MainActivity
String[] toyNames = ToyBox.getToyNames();

Show dummy Data
for (String toyName : toyNames) {
mToysListTextView.append(toyName + "nnn");
}
--------------- or ---------------
for (int i = 0; i<toyNames.lenght; i++) {
mToysListTextView.append(toyNames[i] + "nnn");
}

Make dummy Data
teks.SetText(“Halo”);
teks.SetText(“Akhirat”);
Output :
“Akhirat”
teks.append(“Halo”);
teks.append(“Akhirat”);
Output :
“HaloAkhirat”

Exercise 1.3 - Add Scrolling View

NOW IS YOUR
TIME...
>>Create Layout Sunshine Project

Logging
Log.d(“string key”,”string isi”);
Log.e --> Error
Log.w --> Warning
Log.e --> Info
Log.d --> Debug
Log.v --> Verbose

T02.02-Exercise-AddMenu
- Buat resource “Menu”
- Add MenuItem
- Override onCreateOptionMenu kemudian inflate MenuItem
- Override onOptionItemSelected untuk EventHandling

https://medium.com/@ocittwo/recyclerview-dan-adapternya-ce6332a0833

RecyclerView vs ListView
+ ViewHolder Pattern
+ LayoutManager (Linear, Grid, Staggered)
+ Item animators and item decorators
+ More explicit click listeners

RecyclerView
Source :
LinearLayoutManager GridLayoutManager StaggeredLayoutManager

T03.01-
Exercise-RecyclerViewLayout
1. Add Dependency in build.gradle(Module:app) >sync now
compile 'com.android.support:recyclerview-v7:25.3.1'
2. Add RecyclerView in xml with ID

T03.02-
Exercise-ViewHolder
3. Add item_list.xml design
4. Add Adapter.java
Make ViewHolder Class extends RecyclerView.ViewHolder

RecyclerView
Source :

T03.03-
Exercise-RecyclerViewAdapter
4. Add Adapter.java
- Make ViewHolder Class extends RecyclerView.ViewHolder
- Make Adapter Class Extends
RecylerView.Adapter<RecyclerView.ViewHolder>
- Implement method
- onCreateViewHolder > untuk inflate layout_item
- onBindViewHolder > untuk proses tiap-tiap komponen
- getItemCount > jumlah list data

T03.04-Exercise-
WiringUpRecyclerView
3. Add item_list.xml design
4. Add Adapter.java then setAdapter
5. Add LayoutManager then setLayoutManager

T03.07-Exercise-
RecyclerViewClickHandling
1. Make ListItemClickListener
2. Implement OnClickListener in ViewHolder

My Way
1. Tambahkan pada Constructor Adapter
(int[] data, Context context)
2. Sehingga saat manggil Adapter jadi Adapter(dataAngka,this);
3. holder.cardview.setOnClickLister

LESSON 9
Create Content Provider

1. Create ContentProvider Class
public class FilmContentProvider extends ContentProvider {
MovieDbHelper dbHelper;

Context context = getContext();
dbHelper = new MovieDbHelper(context);
return true;
}
.
.

2. Android Manifest
<application>
.
.
.
.
<provider
android:name=".data.MovieContentProvider"
android:authorities="id.co.imastudio.popmov"

3. DefineURI
ALL FILM
content://id.co.imastudio.recyclerview/listfilm
FILM WITH ID
content://id.co.imastudio.recyclerview/listfilm/#

Final Project
- Grid Layout
- Sort by Popular , Top Rated, and Favorit
- Detail Screen (title, release date, movie poster, vote average,
and plot synopsis, trailer, and review)
- Mark it as a Favorite.
- Networking in background thread
- Content provider to save Favorit offline

Final Project
save app state and restores it via
onSaveInstanceState/onRestoreInstanceState.
