Handle SettingsActivity onBackpressed() the same way as top bar back button

I have a SettingsActivity that has an "up" button included on the top bar. My AettingsActivity also has headers, that load proper settings fragments. By default, when I press the top bar "up" button, it closes the visible fragment and returns to headers, and closes activity if pressed on header view. Howeer, my phone "back" button works different - it just closes the activity. How ca i make "up" arrow and back button work the same way to keep my app consistent? Should I add onBackPressed to my activity, and if so, what should I put there?
My SettingsActivity:
public class SettingsActivity extends AppCompatPreferenceActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setupActionBar();
}
private void setupActionBar() {
ActionBar actionBar = getSupportActionBar();
if (actionBar != null) {
actionBar.setDisplayHomeAsUpEnabled(true);
}
}
#Override
public boolean onMenuItemSelected(int featureId, MenuItem item) {
int id = item.getItemId();
if (id == android.R.id.home) {
if (!super.onMenuItemSelected(featureId, item)) {
NavUtils.navigateUpFromSameTask(this);
}
return true;
}
return super.onMenuItemSelected(featureId, item);
}
#Override
public void onBuildHeaders(List<Header> target) {
loadHeadersFromResource(R.xml.pref_headers, target);
}
protected boolean isValidFragment(String fragmentName) {
return PreferenceFragment.class.getName().equals(fragmentName)
|| NewsPreferenceFragment.class.getName().equals(fragmentName)
|| OtherPreferenceFragment.class.getName().equals(fragmentName);
}
public static class NewsPreferenceFragment extends PreferenceFragment {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.pref_news);
setHasOptionsMenu(true);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == android.R.id.home) {
startActivity(new Intent(getActivity(), SettingsActivity.class));
return true;
}
return super.onOptionsItemSelected(item);
}
}
public static class OtherPreferenceFragment extends PreferenceFragment {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.pref_other);
setHasOptionsMenu(true);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == android.R.id.home) {
startActivity(new Intent(getActivity(), SettingsActivity.class));
return true;
}
return super.onOptionsItemSelected(item);
}
}
}
This is a default code generated from Android Studio when creating new SettingsActivity, just with some changes made to suit my app

You just need to override onBackPressed() method:
#Override
public void onBackPressed() {
NavUtils.navigateUpFromSameTask(this);
}

Navigation Drawer not opening when using android support library v23.4.0

Hello everyone I'm developing an app that uses old navigation drawer approach. When I update 'com.android.support:appcompat-v7:23.1.1' to 'com.android.support:appcompat-v7:23.4.0' my navigation drawer not opening.
I debugged code and look for deprecated items but could not find any error code or message. Everything works perfectly but navigation drawer is not opening. Here is my code. Thanks in advance.

The Drawer is locked.
Change
mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED);
to
mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_UNLOCKED);

Here is the late solution that I find with myself. drawerOpenCloseControl is boolean flag. I am controlling true or false. And then open and close manually.
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
if(drawerOpenCloseControl){
mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_OPEN);
drawerOpenCloseControl = false;
}
else{
mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED);
drawerOpenCloseControl = true;
}
break;
}
return super.onOptionsItemSelected(item);

Here, everything looks normal. But there is no the rest of the code. Maybe you create an activity every second.
I would recommend you to write in support of the admob and clarify the issues. Maybe you're lucky and they will unblock you.

Error On Null Pointer But Still Unsolved on Android Studio

i am a newbie for Android Programming.
Here i have some problem when i want to make an activity (call Category_Setting) that showing list view, but when i switch from main activity to Category_Setting the error report in Android Studio gimme some error like this
java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.ever_ncn.cashflow/com.example.ever_ncn.cashflow.CategorySetting}: java.lang.NullPointerException: Attempt to invoke virtual method 'void android.widget.Button.setOnClickListener(android.view.View$OnClickListener)' on a null object reference

And this is Category_Setting.java (where i get this error)
public class CategorySetting extends Activity {
private SQLiteDatabase db;
private CursorAdapter currAdapter;
private static Button BtnIAddCateg;
private static Button BtnICancelCateg;
private static final String TAG = CategorySetting.class.getSimpleName();

ListView listView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
onButtonClickButtonListener();
//reload();
}
public void reload(){
listView = (ListView) findViewById(R.id.listViewCateg);
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Log.d(TAG, "clicked on item: " + position);
}
}
);
}
#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_category_setting, menu);
return true;
}
public void onButtonClickButtonListener(){
BtnIAddCateg = (Button)findViewById(R.id.btnAddNewCateg);
BtnIAddCateg.setOnClickListener(
new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intentAddCateg = new Intent ("com.example.ever_ncn.cashflow.AddCategory");
startActivity(intentAddCateg);
}
}
);
BtnICancelCateg = (Button)findViewById(R.id.btnCancelCateg);
BtnICancelCateg.setOnClickListener(
new View.OnClickListener() {
#Override
public void onClick(View v) {
finish();
}
}
);
}
#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();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}

In this method in Category_Setting.java:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
onButtonClickButtonListener();
//reload();
}
you forgot to load the layout. You should add some code like you used in the MainActivity:
setContentView(R.layout.activity_main);
Right now, the layout is not loaded at all, so
BtnINewTrans = (Button)findViewById(R.id.btnNewTrans);
will return null.

onManagerConnected status returning value 2 [Market error]

OpenCVLoader.initAsync(OpenCVLoader.OPENCV_VERSION_2_4_10, this, mLoaderCallback);
}
}
The status value is getting set to 2, even though the OpenCV manager is installed on the phone. Need help in resolving the issue.When prompted to install opencv manager, it returns package installation failed

Well I figured it out myself. This was because the version code in initAsnyc was set to OPENCV_VERSION_2_4_10 whereas the openCV manager version was 2.4.9. So changed the version in initAsync to OPENCV_VERSION_2_4_9.
