Task 1
Buat project baru dan masukkan ke dalam layout activity main

dan masukkan ke layout content_main

Lalu pada java MainActivity tulis seperti berikut
package com.example.android.appwithsettings;
import android.content.Intent;
import android.content.SharedPreferences;
import android.os.Bundle;
import android.support.design.widget.FloatingActionButton;
import android.support.design.widget.Snackbar;

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
FloatingActionButton fab = findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {

}

if (id == R.id.action_settings) {
Intent intent = new Intent(this,
SettingsActivity.class);
startActivity(intent);
return true;
}
return super.onOptionsItemSelected(item);
}
}
Kemudian Buat dan masukkan SettingActivity seperti dibawah ini
package com.example.android.appwithsettings;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
public class SettingsActivity extends AppCompatActivity {
public static final String
KEY_PREF_EXAMPLE_SWITCH = "example_switch";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getSupportFragmentManager().beginTransaction()
.replace(android.R.id.content,
new SettingsFragment()).commit();
}
}
Buat dan masukkan SettingFragment seperti dibawah
package com.example.android.appwithsettings;
import android.os.Bundle;
import android.support.v7.preference.PreferenceFragmentCompat;
public class SettingsFragment extends PreferenceFragmentCompat {
/**
* Called during onCreate(Bundle) to supply the preferences for this

*
* @param savedInstanceState If the fragment is being re-created from

* @param rootKey If non-null, this preference fragment
* should be rooted with this key.
*/
@Override
public void onCreatePreferences(Bundle savedInstanceState,
String rootKey) {
setPreferencesFromResource(R.xml.preferences, rootKey);
}
}
