Hi everyone I am currently developing an android app, I am having some confusions in the code, I have a main activity in which I store some array values.
I have two xml files(one mainactivity.xml and other the other one is listview.xml)
In main activity.xml there are four switches, when I click any particular switch it should take me to the listview.xml, with a corresponding array displayed on list view by list view adapter. The code is as follows
public class MainActivity extends ActionBarActivity {
ListView l;
Button chem = (Button) findViewById(R.id.button4);
public String[] contentc = {
"Abundance",
"Anxiety",
"Bruxism",
"Discipline",
"Drug Addiction"
};
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
l= (ListView) findViewById(R.id.listview);
final ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, R.layout.list_element, contentp);
chem.setOnClickListener(new OnClickListener() {
public void onClick(View v)
{
//DO SOMETHING! {RUN SOME FUNCTION ... DO CHECKS... ETC}
setContentView(R.layout.list);
l.setAdapter(adapter);
}
});
}
#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);
}
}
Intent intent = new Intent(activity2.this, activity1.class);
intent.putExtra("message", message);
startActivity(intent);
In activity1, in onCreate(), you can get the String message by retrieving a Bundle (which contains all the messages sent by the calling activity) and call getString() on it :
Bundle bundle = getIntent().getExtras();
String message = bundle.getString("message")

I have created a ListView and create A ,B and C in the list
now , i want when the user click A ,it led the user to a new activity called D. when he clicks B, led him to new Activity called E,Clicks C and go to Activity F.
what should I do to accomplish that?
here is my code
public class MainActivity extends Activity implements
OnItemClickListener{
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ListView support_device_list=(ListView)
findViewById(R.id.support_device_list);
support_device_list.setOnItemClickListener(this);
}
#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);
}
--------------------------------------------------------------------------------The new code
is it Like that?
public class MainActivity extends Activity implements
OnItemClickListener{
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ListView support_device_list=(ListView)
ListView list = (ListView) findViewById(R.id.listview);

I read some question regarding this but all the answers are about fragments and there is question similar to this one but the answer is incomplete, I want to reuse a set of layout or codes into multiple activities, i created a baseActivity that extends into Activity with the code below.
I also read that you need to put the code in the onCreateOptionMenu but it is still not working. (the code in baseacitivty xml is working, and homepage xml is working but does not show the navigation_layout)
public class BaseActivity extends Activity {
private ImageButton ibButtonHome;

Base activity to extend the navigation drawer in other activities you can follow this link , described well. it is well tested i followed the same :)
http://androiddeveloperdemo.blogspot.in/2014/08/android-navigation-drawer-with-multiple.html
You can get the same action bar in other activities by declaring in AndroidManifest.xml like this
<activity
android:name=".SettingsActivity"
android:label="#string/activity_title"
android:theme="#style/AppTheme" />
For different menu options define a xml file under menu folder in android studio and inflate that file in
onCreateOptionsMenu(Menu) overridden method of your activty
I have a first activity ("Home"), with two buttons: one is called About and leads to activity About and the second is named List and leads to the activity List.
Manifest.xml should be fine, but I get a load of tiny petty errors I can't fix up by myself, regrettably.
Home.class is the following
Public class Home extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home);
Button AboutButton = (Button)findViewById(R.id.About);
AboutButton.setOnClickListener(new View.OnClickListener()){
#Override
public void onClick(View view); {
Intent openAbout = new Intent(Home.this, About.class);
startActivity(openAbout);
}
}
Button ListButton = (Button)findViewById(R.id.List);
ListButton.setOnClickListener(new View.onClickListener());{
#Override
public void onClick(View view); {
Intent openList = new Intent(Home.this, List.class);
startActivity(openList);
}
}
}
#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_home, 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();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
while About.class is like this
public class About extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_about);
Button ReturnButton = (Button)findViewById(R.id.Return);
ReturnButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent returnhome = new Intent(About.this, Home.class);
startActivity(returnhome);
}
public void onClick(View view); {
Intent returnhome = new Intent(About.this, Home.class);
startActivity(returnhome);
}
}
}
#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_about, 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();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
and List is like this:
public class List extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_list);
Button ReturnButton = (Button)findViewById(R.id.Return);
ReturnButton.setOnClickListener(new View.OnClickListener()){
#Override
public void onClick(View view) {
Intent returnhome = new Intent(About.this, Home.class);
startActivity(returnhome);
}
}
}
#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_list, 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();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
I get lot of red light bulbs, saying, for instance that ")" or ";" is expected or (worse) onClickListener cannot be resolved
Last but not least: I copied this code online and I was wondering why after "View" there is a "view"; what does it mean?
I copied your code and I see fails everywhere... let me explain you what's going on ...
HOME CLASS
1.- You have to remove the ")"
2.- You don't have to ";" when you call onClick()
3.- When you are don on your onClick() NOW you have to close it, you missed the ");"
AboutButton.setOnClickListener(new View.OnClickListener()){ //<-- Just remove one
#Override
public void onClick(View view); { //<-- Remove this ";"
Intent openAbout = new Intent(Home.this, About.class);
startActivity(openAbout);
}
}//Here goes ");"
4.- The ListButton has the same issues so just fix it as you will fix the first one.
ABOUT CLASS
1.-On this case you have the setOnClickListener() ok, BUT why you have two onClick(View view)? It's not necessary just remove one of them.
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_about);
Button ReturnButton = (Button) findViewById(R.id.Return);
ReturnButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent returnhome = new Intent(About.this, Home.class);
startActivity(returnhome);
}
});
}
LIST CLASS
1.-Well in your List class you have made the same error as the first one... Your onClickListener() it's wrong.
2.-Once again you included an unnecessary ")" on new View.OnClickListener() just remove it,
3.-Another fail that I'm seeing is that you are trying to make an Intent but you are refering that you are on About.this and you are NOT. You are on List class so you have ot put List.this because the first parameter refers :
A Context as its first parameter (this is used because the Activity class is a subclass of Context)
More information about Intents
4.- You need to close again the setOnClickListener()
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_list);
Button ReturnButton = (Button)findViewById(R.id.Return);
ReturnButton.setOnClickListener(new View.OnClickListener()){ //<-- remove one ")"
#Override
public void onClick(View view) {
Intent returnhome = new Intent(About.this, Home.class); //<-- Remove About.this and put List.this
startActivity(returnhome);
}
}//<-- Close the setOnClickListener() with ");"
}
It's okay guy, this is your first question and I'll answer it, but NOW as I've made the favor to take my time and explain to you what was wrong on your code take your time to :
How do I as a question on StackOverflow
Learn some Android basics
And the most IMPORTANT THING
DO NOT COPY PASTE AN INTERNET CODE if you don't know the basics, I mean you can copy paste the code, but you'll face with this problem every time you do this, so first of all read the tutorial, make an examples, and you'll improve every day.
I have an activity which has an edit text which becomes visible when a button is clicked. I fill the edit text up and click another button. On clicking this button the edit text content must be sent to another activity.The first activity takes the edit text and queries a list of data from my Parse database and shows it in a ListView in the Second Activity.But whenever i click the first button(after entering the string) the app crashes.This is the first activity
public class MainActivity extends ActionBarActivity {
String name;
EditText search;
Button g;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
setUpSpinners();
Parse.initialize(this, "AAh5US7zhbYyFBexsv07cjo34ZZiB7KNe9SuTv7e",
"eKUG1pYaV50hVyDC9d4qZc4qf1dCtOTqnX92eGJV");
PushService.setDefaultPushCallback(this, MainActivity.class);
ParseInstallation.getCurrentInstallation();
search = (EditText) findViewById(R.id.search);
g = (Button) findViewById(R.id.Go);
}
#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);
}
public void byName(View v) {
search.setVisibility(View.VISIBLE);
search.requestFocus();
g.setVisibility(View.VISIBLE);
}
public void Go(View v) {
name = search.getText().toString();
final Intent i;
i = new Intent(MainActivity.this, ResterauntList1.class);
i.putExtra("restrauntName", name);
startActivity(i);
}
}
In the above byName is the onClick for making the EditText visible, and Go is the onClick for getting my EditText string and passing it to the next activity. The second activity is below
public class ResterauntList1 extends Activity {
String rValue;
ArrayAdapter<String> adapter;
ProgressDialog mProgressDialog;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_resteraunt_list1);
Bundle bdl = getIntent().getExtras();
rValue = bdl.getString("restrauntName");
setContentView(R.layout.activity_resteraunt_list);
populateList(rValue, "name");
}
private void populateList(final String Value, final String Key) {
ParseQueryAdapter.QueryFactory<ParseObject> factory = new ParseQueryAdapter.QueryFactory<ParseObject>() {
#Override
#SuppressWarnings({ "unchecked", "rawtypes" })
public ParseQuery create() {
ParseQuery query = new ParseQuery("resdb");
query.whereEqualTo(Key, Value);
return query;
}
};
ParseQueryAdapter<ParseObject> adapter = new ParseQueryAdapter<ParseObject>(
this, factory);
adapter.setTextKey("name");
adapter.addOnQueryLoadListener(new OnQueryLoadListener<ParseObject>() {
#Override
public void onLoading() {
mProgressDialog = new ProgressDialog(ResterauntList1.this);
mProgressDialog.setTitle("Searching for " + Value);
mProgressDialog.setMessage("Loading...");
mProgressDialog.setIndeterminate(false);
mProgressDialog.show();
}
#Override
public void onLoaded(List<ParseObject> objects, Exception e) {
mProgressDialog.dismiss();
}
});
final ListView listView = (ListView) findViewById(R.id.restListView1);
listView.setAdapter(adapter);
listView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
ParseObject object = (ParseObject) listView
.getItemAtPosition(position);
String Id = object.getObjectId();
Intent i = new Intent(getApplicationContext(),
SingleRestraunt.class);
i.putExtra("restId", Id);
startActivity(i);
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.resteraunt_list1, 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);
}
}
The error as stated above occurs when I click the Go button.The error is
09-02 14:58:46.443: E/AndroidRuntime(3061): Process: com.example.gastronomaapp, PID: 3061
09-02 14:58:46.443: E/AndroidRuntime(3061): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.gastronomaapp/com.example.gastronomaapp.ResterauntList1}: java.lang.NullPointerException
Any idea where I am making a mistake? The funniest thing almost the same code has worked in another part of my app. absolutely clueless whats wrong.
Bundle bdl = getIntent().getExtras();
rValue = bdl.getString("restrauntName");
change to
rValue = getIntent().getStringExtra("restrauntName");
You put the string directly on the intent, not packaged in a bundle.
How can I remove a item from a ListActivity from a button on another Activity, the thing is,
I have this ListActivity:
public class ListaEventos extends ListActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Override
protected void onResume() {
super.onRestart();
republicar();
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.lista_eventos, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.criar_evento:
Intent criar = new Intent(this, CriarEvento.class);
startActivity(criar);
return true;
default:
return super.onOptionsItemSelected(item);
}
}
public void republicar() {
List<DadosEvento> eventos = MySingleton.getInstance().getEventos();
setListAdapter(new ArrayAdapter<DadosEvento>(this, android.R.layout.simple_list_item_1, eventos));
}
#Override
public void onListItemClick(ListView listView, View view, int position, long id) {
DadosEvento clickNumber = MySingleton.getInstance().getEventos().get(position);
Intent intent = new Intent(this, ExibirEvento.class);
Bundle exibirEvento = new Bundle();
exibirEvento.putString("exibirNome", clickNumber.getNome());
exibirEvento.putString("exibirData", clickNumber.getData());
exibirEvento.putString("exibirEnd", clickNumber.getEndereco());
exibirEvento.putString("exibirTel", clickNumber.getTel());
intent.putExtras(exibirEvento);
startActivity(intent);
}
}
Other Activity:
public class ExibirEvento extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_exibir_evento);
Intent intent = getIntent();
Bundle exibirEvento = intent.getExtras();
String exibirNome = exibirEvento.getString("exibirNome");
String exibirData = exibirEvento.getString("exibirData");
String exibirEnd = exibirEvento.getString("exibirEnd");
String exibirTel = exibirEvento.getString("exibirTel");
TextView exibir_nome = (TextView) findViewById(R.id.exibirevento_edittext_nome);
exibir_nome.setText(exibirNome);
TextView exibir_data = (TextView) findViewById(R.id.exibirevento_edittext_data);
exibir_data.setText(exibirData);
TextView exibir_end = (TextView) findViewById(R.id.exibirevento_edittext_end);
exibir_end.setText(exibirEnd);
TextView exibir_tel = (TextView) findViewById(R.id.exibirevento_edittext_tel);
exibir_tel.setText(exibirTel);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.exibir_evento, menu);
return true;
}
public void sairExibicao(View v) {
finish();
}
}
Now, on the ExibirEvento is where it shows me the infos about the Party, and there I need a button that removes that item from the List.
Well there are several scenarios that you can follow.
Use startActivityForResult instead of startActivity and then override the onActivityResult method and catch a proper requestCode and result (e. g. RESULT_OK) and delete current item and notifyDataChanged the adapter
Use singelton class, create newInstance, set values, and then refere to it from ExibirEvento
Use the database, and take advantage of ContentProvider and Loader, and pass only the ID of the entry to ExibirEvento
I think that the 3 option is the best way to go for.
