I am currently building for a minimum SDK of 10, so I have to use the android-support-v7-appcompat library to implement ActionBar. I have setup the ActionBar, but I want to now add a ListActivity, however this requires extending my class and Java doesn't have multiple inheritance. What should I do?
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 items for use in the action bar
MenuInflater inflater = getMenuInflater();
getSupportActionBar().setIcon(R.drawable.ic_action_search);
getSupportActionBar().setDisplayShowHomeEnabled(false);
getSupportActionBar().setDisplayShowTitleEnabled(false);
inflater.inflate(R.menu.main_activity_actions, menu);
return super.onCreateOptionsMenu(menu);
}
}
ListActivity hasn't been ported to AppCompat. Probably because you should consider it 'deprecated', and instead use a ListFragment.
Fragments will work with a ActionBarActivity, just make sure they are fragments from the support library.
Have a read through this link about fragments.
For your use case, I would just define the fragment in xml.
The easiest way to do this is to use a ListFragment inside of the ActionBarActivity. I did it like this:
public class MyActivity extends ActionBarActivity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
MyFragment fragment = new MyFragment();
getSupportFragmentManager().beginTransaction().replace(android.R.id.content, fragment).commit();
}
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home: {
finish();
break;
}
default: {
break;
}
}
return true;
}
public static class MyFragment extends ListFragment {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
...
}
public void onListItemClick(ListView listView, View view, int position, long id) {
...
}
}
}
This way you don't even need an xml for it, and it works well.

I am new to Android.
I am trying to refer a View by Id from a separate class than MainActivity.
Note: My app has single activity.
Main Activity:
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState)//Activity Oncreate callback
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) //Oncreate Options_menu callback
{
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main_menu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch(item.getItemId()) {
case R.id.option1:
//Here am calling a method from another class
SecondClass secondClassObject=new SecondClass();
secondClassObject.method1();
}
return true;
}
Second Class:
public class SecondClass {
public void method1(){
TextView tv1 = (TextView)findViewById(R.id.textView);
tv1.setText("");
}
}
How to refer to the textView by ID in the SecondClass? How to set the context as MainActivity in this SecondClass?
Add an Activity parameter for your method
public void method1(Activity act){
TextView tv1 = (TextView)act.findViewById(R.id.textView);
tv1.setText("");
}
From your activity define an Activity variable Activity act; so as to use it across other functions .Assign a value of your Activity to the variable act=this; and finaly use it on the function you want.
public class MainActivity extends AppCompatActivity {
Activity act;
#Override
protected void onCreate(Bundle savedInstanceState)//Activity Oncreate callback
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
act=this;
}
#Override
public boolean onCreateOptionsMenu(Menu menu) //Oncreate Options_menu callback
{
act=this;
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main_menu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch(item.getItemId()) {
case R.id.option1:
//Here am calling a method from another class
//SecondClass secondClassObject=new SecondClass();
//secondClassObject.method1();
SecondClass secondClassObject=new SecondClass();
secondClassObject.method1(act);
}
return true;
}
you can also pass the parent layout view
public void method1(View act){
TextView tv1 = (TextView)act.findViewById(R.id.textView);
tv1.setText("");
}
And call it like so
SecondClass secondClassObject=new SecondClass();
secondClassObject.method1(findViewById(R.id.your_parent_layout));
Avoid using passing Activity method if its not absolutely necessary to avoid possibilities of memory leaks.
I'm working on the android self study Sunshine app and I'm having trouble getting extra menu entries in the action bar.
The most likely reason I've found, is that the OnCreate method of my frame class is not being called and thus the menu is not being inflated.
Here's my MainActivity code:
public class MainActivity extends ActionBarActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Log.d("MainActivity","OnCreate Started 1");
if (savedInstanceState == null) {
Log.d("MainActivity","OnCreate Started 2");
ForecastFragment MyFragment = new ForecastFragment();
if (MyFragment == null){
Log.d("MainActivity","OnCreate Started 3");
}
else{
getSupportFragmentManager().beginTransaction()
.add(R.id.container, MyFragment)
.commit();}
}
}
Here is now the code of my ForecastFragment class:
public class ForecastFragment extends Fragment {
public ForecastFragment() {
}
//#Override
protected void OnCreate(Bundle savedInstanceState){
Log.d("Forecastfragment","OnCreate Started");
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
}
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
// Inflate the menu; this adds items to the action bar if it is present.
inflater.inflate(R.menu.forecastfragment, menu);
}
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_refresh) {
FetchWeatherTask WeatherTask = new FetchWeatherTask();
WeatherTask.execute();
return true;
}
return super.onOptionsItemSelected(item);
}
When I run the app, I don't see the logging that the OnCreate method of the ForecastFragment class is being called.
Any ideas?
This is not the exact inherited onCreate method of Fragment
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Log.i(TAG, "onCreate()");
}
it should be onCreate not OnCreate
When trying to make an android app, I encountered the error:
No enclosing instance of the type MainActivity is accessible in scope on the line
Toast.makeText(MainActivity.this, "Swag", Toast.LENGTH_SHORT).show();
This is my MainActivity.java:
public class MainActivity extends ActionBarActivity {
static Button btn;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
if (savedInstanceState == null) {
getSupportFragmentManager().beginTransaction()
.add(R.id.container, new PlaceholderFragment()).commit();
}
}
#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) {
return true;
}
return super.onOptionsItemSelected(item);
}
/**
* A placeholder fragment containing a simple view.
*/
public static class PlaceholderFragment extends Fragment implements View.OnClickListener {
public PlaceholderFragment() {
}
#Override
public void onClick(View v) {
Toast.makeText(MainActivity.this, "Swag", Toast.LENGTH_SHORT).show();
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_main, container,false);
btn=(Button) rootView.findViewById(R.id.test_button);
btn.setOnClickListener(this);
return rootView;
}
}
}
You must use getActivity() inside the fragment.
Be careful, if you are doing some background job, or any other async task when it return, getActivity() may be null. So every time you use it check for null.
Further information on fragments, you can use this.
I need to extend Two classes from a Single Class.My class Wants to extend Both ListActivity & MainActivity.

EDIT
I need to Extend it.Because the MainActivity has the navigation drawer.Now ConnectionEditActivity
doesn't shows the navigationDrawer nor the ActionBar .But i need to show the ActionBar
Any Suggestions ??
In Java you can't extend multiple classes, and for a good reason. Take for example what you are trying to accomplish by extending MainActivity and ListActivity. In your new class, when you call:
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
...
}
Which onCreate() are you overriding? The one from ListActivity, or the one from MainActivity?
What the link you posted is saying is that instead of inheriting from another object, you compose your new object of the one you are trying to use. For example:
public class NewClass extends OldClass1 {
private OldClass2 mOldClass2 = new OldClass2();
#Override
public methodFromOldClass1() {
}
public methodFromOldClass2() {
mOldClass2.methodFromOldClass2();
}
}
The problem with this approach is that the methods from MainActivity and ListActivity are still going to have the same name, which although you can work around, it will become a headache quickly.
So the problem is a result of how you designed your class hierarchy. You will need to think about what functions you need from MainActivity, and what functions from ListActivity and choose how to reimplement your objects.
My Suggestion, since ListActivity only makes it slightly easier to work with lists (not that much easier) you can just skip it and implement the code related to the list on your own, and that way you can just extend MainActivity
You need to start by identifying what parts of MainActivity you need to inherit from, and what do you need from ListActivity.
Then, you have various possibilities:
Trivially, not extending ListActivity. Extending ListActivity only provides you with utility methods to work with the ListView, but you can totally have a ListView in an Activity without it being a ListActivity.
Create a utility class that contains extracted methods you need from MainActivity and call these methods from both your new class and MainActivity.
Modify MainActivity so that it extends ListActivity. After all it does contain a ListView (you'd loose the ActionBar thing, though).
New to ActionBar and Fragments but familiar with Android in general.
I have been following a few tutorial. So far I have the following:
3 Fragments that I want to navigate between (each has an overriden onCreateView() and loads a simple view)
A custom TabListener for the ActionBar (I believe the problem is there, see bottom of post for code)
A hosting Activity in which this is all performed
The Activity code:
public class Activity_Home extends Activity
{
ActionBar actionBar;
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home);
actionBar = getActionBar(); // Get reference to ActionBar
// Add some navigation tabs...
// 1. Enable ActionBar navigation tabs
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
actionBar.setDisplayShowTitleEnabled(false);
// 2. Add the tabs
Tab programTab = actionBar.newTab();
Tab settingsTab = actionBar.newTab();
Tab historyTab = actionBar.newTab();
programTab.setText("Program")
.setTabListener(new TabListener<Fragment_Program>(
this, R.id.fragmentParent, Fragment_Program.class));
settingsTab.setText("Settings")
.setTabListener(new TabListener<Fragment_Settings>(
this, R.id.fragmentParent, Fragment_Settings.class));
historyTab.setText("History")
.setTabListener(new TabListener<Fragment_History>(
this, R.id.fragmentParent, Fragment_History.class));
actionBar.addTab(programTab);
actionBar.addTab(settingsTab);
actionBar.addTab(historyTab);
}
}
My Fragments:
public class Fragment_Program extends Fragment
{
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState)
{
return inflater.inflate(R.layout.fragment_program, null);
}
}
..
public class Fragment_History extends Fragment
{
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState)
{
return inflater.inflate(R.layout.fragment_history, null);
}
}
..
public class Fragment_Settings extends Fragment
{
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState)
{
return inflater.inflate(R.layout.fragment_settings, null);
}
}
Lastly, my TabListener which has been pretty much based on the official Google example. The fragmentContainer (int) is the XML resource ID of the LinearLayout in the Activities layout that is the direct parent of all of these Fragments.
public class TabListener <T extends Fragment> implements ActionBar.TabListener
{
private Fragment fragment;
private int fragmentContainer;
private final Activity activity;
private final Class<T> fragmentClass;
/** Constructor used each time a new tab is created.
* #param activity The host Activity, used to instantiate the fragment
* #param tag The identifier tag for the fragment
* #param fragmentClass The fragment's Class, used to instantiate the fragment
*/
public TabListener(Activity activity, int fragmentContainer, Class<T> fragmentClass)
{
this.activity = activity;
this.fragmentContainer = fragmentContainer;
this.fragmentClass = fragmentClass;
}
#Override
public void onTabReselected(Tab arg0, FragmentTransaction arg1)
{
// User selected the already selected tab. Usually do nothing.
}
#Override
public void onTabSelected(Tab tab, FragmentTransaction ft)
{
// Check if the fragment is already intialized
if (fragment == null)
{
// If not, instatiate and add it to the Activity
fragment = Fragment.instantiate(activity, fragmentClass.getName());
ft.add(fragmentContainer, fragment);
}
else
{
ft.attach(fragment);
}
}
#Override
public void onTabUnselected(Tab tab, FragmentTransaction ft)
{
if (fragment != null)
{
// Detach the fragment, because another one is being attached
ft.detach(fragment);
}
}
}
So the app loads, the tabs are there, I can select them but they don't seem to be linked to each other and I am not really sure how to proceed.
Any suggestions would be great!
Cheers
BONUS QUESTION: The ActionBar is also below the existing ActionBar.. goal was to replace it, not make another one underneath.. again any suggestions would be great!
Fixed it!
I changed my approach from using the Fragment Container ID (which did make and does still make more sense to me..) with String tags as per this example Good complete Fragment and ActionBar example and the official Google example.
I imagine that you want the tabs to be connected in a way that you can swipe between tabs, in order to accomplish this, you should consider a ViewPager.
Here's the XML by the way:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:orientation="vertical">
<android.support.v4.view.ViewPager
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"/>
</LinearLayout>
Here's some sample code you can use:
public class MyTabActivity extends FragmentActivity implements ActionBar.TabListener, ViewPager.OnPageChangeListener {
//What item on the pager is being displayed
private int mCurPagerItem = 0;
//This will be set to the pageer to handle navigation
private SectionsPagerAdapter mSectionsPagerAdapter;
private ViewPager mViewPager;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home);
final ActionBar mActionBar = getActionBar();
mActionBar.setDisplayShowHomeEnabled(false);
mActionBar.setDisplayShowTitleEnabled(false);
mActionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
//add the tabs
mActionBar.addTab(mActionBar.newTab().setIcon(R.drawable.your_icon).setTabListener(this));
mActionBar.addTab(mActionBar.newTab().setIcon(R.drawable.your_icon2).setTabListener(this));
mActionBar.addTab(mActionBar.newTab().setIcon(R.drawable.your_icon3).setTabListener(this));
mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());
mViewPager = (ViewPager) findViewById(R.id.pager);
mViewPager.setAdapter(mSectionsPagerAdapter);
mViewPager.setOnPageChangeListener(this);
}
public class SectionsPagerAdapter extends FragmentPagerAdapter {
public SectionsPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int position) {
switch (position) {
case 0:
Fragment one = new Fragment_Program();
return one ;
case 1:
Fragment two = new Fragment_Settings();
return two ;
case 2:
Fragment three = new Fragment_History();
return three ;
default:
break;
}
return null;
}
#Override
public int getCount() {
return 3;
}
#Override
public CharSequence getPageTitle(int position) {
switch (position) {
case 0:
return getString(R.string.title_one);
case 1:
return getString(R.string.title_two);
case 2:
return getString(R.string.title_three);
}
return null;
}
}
#Override
public void onPageScrollStateChanged(int arg0) {}
#Override
public void onPageScrolled(int arg0, float arg1, int arg2) {}
#Override
public void onPageSelected(int arg0) {
//When a Page is selected, make that the current navigation item
getActionBar().setSelectedNavigationItem(arg0);
}
#Override
public void onTabReselected(Tab tab, FragmentTransaction ft) {
//Back to top maybe?
}
#Override
public void onTabSelected(Tab tab, FragmentTransaction ft) {
//get the position
final int pos = tab.getPosition();
//Tell the viewpager to scroll to that page
mViewPager.setCurrentItem(pos);
mCurPagerItem = pos;
}
#Override
public void onTabUnselected(Tab tab, FragmentTransaction ft) {
}
To answer your bonus question, on your Manifest, try adding the following line withing the specified activity tag:
android:uiOptions="splitActionBarWhenNarrow"
