Contoh Aplikasi Android Settings atau Preference dengan Eclipse ADT – Page 2

Kita tambahkan class “SettingsActivity” di package “com.wijaksana.android.settings” dengan extend ke “android.preference.PreferenceActivity” dan implements ke “SharedPreferences.OnSharedPreferenceChangeListener”, berikut scriptnya:

public class SettingsActivity extends PreferenceActivity implements SharedPreferences.OnSharedPreferenceChangeListener {
	private SharedPreferences sharedPreferences;

	@SuppressWarnings("deprecation")
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		addPreferencesFromResource(R.xml.preference);

	}	
	
	@SuppressWarnings("deprecation")
	@Override
	protected void onResume() {
		super.onResume();
		
		sharedPreferences = getPreferenceManager().getSharedPreferences();
		sharedPreferences.registerOnSharedPreferenceChangeListener(this);
		
		PreferenceScreen preferenceScreen = getPreferenceScreen();
		for (int i = 0; i < preferenceScreen.getPreferenceCount(); i++) {
			setSummary(getPreferenceScreen().getPreference(i));
		}
	}
	
	@Override
	protected void onPause() {
		sharedPreferences.unregisterOnSharedPreferenceChangeListener(this);
		super.onPause();
	}

	@SuppressWarnings("deprecation")
	@Override
	public void onSharedPreferenceChanged(
			SharedPreferences paramSharedPreferences, String key) {
		Preference pref = getPreferenceScreen().findPreference(key);
		setSummary(pref);
	}

	private void setSummary(Preference preference) {
		if (preference instanceof MyEditTextPreference) {
			preference.setSummary(((MyEditTextPreference) preference).getText().toString());
		}
	}
}

public class SettingsActivity extends PreferenceActivity implements SharedPreferences.OnSharedPreferenceChangeListener {

private SharedPreferences sharedPreferences;

@SuppressWarnings("deprecation")

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

addPreferencesFromResource(R.xml.preference);

}

@SuppressWarnings("deprecation")

@Override

protected void onResume() {

super.onResume();

sharedPreferences = getPreferenceManager().getSharedPreferences();

sharedPreferences.registerOnSharedPreferenceChangeListener(this);

PreferenceScreen preferenceScreen = getPreferenceScreen();

for (int i = 0; i < preferenceScreen.getPreferenceCount(); i++) {

setSummary(getPreferenceScreen().getPreference(i));

}

@Override

protected void onPause() {

sharedPreferences.unregisterOnSharedPreferenceChangeListener(this);

super.onPause();

}

@SuppressWarnings("deprecation")

@Override

public void onSharedPreferenceChanged(

SharedPreferences paramSharedPreferences, String key) {

Preference pref = getPreferenceScreen().findPreference(key);

setSummary(pref);

}

private void setSummary(Preference preference) {

if (preference instanceof MyEditTextPreference) {

preference.setSummary(((MyEditTextPreference) preference).getText().toString());

}

Buka class “MainActivity” lalu tambahkan script menjadi seperti dibawah ini:

public class MainActivity extends ActionBarActivity {

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
	}

	@Override
	public boolean onCreateOptionsMenu(Menu menu) {
		// Inflate the menu; this adds items to the action bar if it is present.
		getMenuInflater().inflate(R.menu.main, menu);
		return true;
	}

	@Override
	public boolean onOptionsItemSelected(MenuItem item) {
		// Handle action bar item clicks here. The action bar will
		// automatically handle clicks on the Home/Up button, so long
		// as you specify a parent activity in AndroidManifest.xml.
		int id = item.getItemId();
		if (id == R.id.action_settings) {
			Intent modifySettings=new Intent(MainActivity.this, SettingsActivity.class);
			startActivity(modifySettings);
			
			return true;
		}
		return super.onOptionsItemSelected(item);
	}
}

public class MainActivity extends ActionBarActivity {

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

}

@Override

public boolean onCreateOptionsMenu(Menu menu) {

// Inflate the menu; this adds items to the action bar if it is present.

getMenuInflater().inflate(R.menu.main, menu);

return true;

}

@Override

public boolean onOptionsItemSelected(MenuItem item) {

// Handle action bar item clicks here. The action bar will

// automatically handle clicks on the Home/Up button, so long

// as you specify a parent activity in AndroidManifest.xml.

int id = item.getItemId();

if (id == R.id.action_settings) {

Intent modifySettings=new Intent(MainActivity.this, SettingsActivity.class);

startActivity(modifySettings);

return true;

}

return super.onOptionsItemSelected(item);

}

Buka file “AndroidManifest.xml” daftarkan activity “SettingsActivity” seperti terlihat dibawah ini:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.wijaksana.android.settings"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="21" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity
            android:name=".SettingsActivity" >
        </activity>
    </application>

</manifest>

<?xml version="1.0" encoding="utf-8"?>

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

package="com.wijaksana.android.settings"

android:versionCode="1"

android:versionName="1.0" >

<uses-sdk

android:minSdkVersion="8"

android:targetSdkVersion="21" />

<application

android:allowBackup="true"

android:icon="@drawable/ic_launcher"

android:label="@string/app_name"

android:theme="@style/AppTheme" >

<activity

android:name=".MainActivity"

android:label="@string/app_name" >

<intent-filter>

</intent-filter>

</activity>

<activity

android:name=".SettingsActivity" >

</activity>

</application>

</manifest>
