I have ToolbarCustom that has two items and an item can be clicked to open or close the layout. I am wondering how can I use the same item for opening and closing layout?
This my Code, but the variable openLayout is not defined:
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();
linearLayout = findViewById(R.id.show);
boolean openLayout=true;
if (id == R.id.action_categure) {
if (openLayout) {
linearLayout.setVisibility(View.VISIBLE);
openLayout=false;
} else {
linearLayout.setVisibility(View.GONE);
openLayout =true;
}
}
if (id==R.id.action_card){
return true;
}
return super.onOptionsItemSelected(item);
}
boolean firstTimeClick = true; //global variable
boolean secondTimeClick = false; //global variable
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();
linearLayout = findViewById(R.id.show);
if (id == R.id.action_categure) {
if (firstTimeClick) {
firstTimeClick = false;
secondTimeClick= true;
linearLayout.setVisibility(View.GONE);
} else if (secondTimeClick){
firstTimeClick= true;
secondTimeClick= false;
linearLayout.setVisibility(View.VISIBLE);
}
}
if (id==R.id.action_card){
return true;
}
return super.onOptionsItemSelected(item);
}
Is that what you want to achieve?Hope I helped you.

I have an acivity with appbar and a fullsecreen dialogfragment with appbar (that dialog is called from the activity).
I have set some action when the home button of the activity is pressed, and when the home button og the dialogfragment is pressed it shoud close the dialog.
I have notice that the two buttons have the same id (android.R.id.home). and aparently there is a conflict when the method "onOptionsItemSelected" is called because when I press the home button of the dialog it doesn't work, but if a remove the portion of the code on the activity (if id == android.R.id.home)
it works fine and the dialog dismiss.
What should I do?. is there way to prevent this conflict , maybe set a diferent id for the home button?
this is the method of the activity
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_logout) {
exitApp();
return true;
}
else if ((id == android.R.id.home) && searchActivated) {
drawer.setDrawerLockMode(DrawerLayout.LOCK_MODE_UNLOCKED);
toggle.syncState();
searchActivated=false;
reload_fragment_data();
return true;
}
else if ((id == android.R.id.home) && (!searchActivated))
{
drawer.openDrawer(GravityCompat.START); // OPEN DRAWER
return true;
}
return super.onOptionsItemSelected(item);
}
this is the method of the dialogfragment
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.action_next) {
pager.setCurrentItem(pager.getCurrentItem() + 1);
updateTitle();
return true;
} else if (id==R.id.action_previous)
{
pager.setCurrentItem(pager.getCurrentItem() - 1);
updateTitle();
return true;
}
else if (id == android.R.id.home) {
dismiss();
return true;
}
return super.onOptionsItemSelected(item);
}
You can apply and try this solution in activity.
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();
Fragment fragment = getFragmentManager().findFragmentById(R.id.fragment_container);
//noinspection SimplifiableIfStatement
if (id == R.id.action_logout) {
exitApp();
return true;
}
else if ((id == android.R.id.home) && searchActivated && !(fragment instanceof DialogFragmentClassName)) {
drawer.setDrawerLockMode(DrawerLayout.LOCK_MODE_UNLOCKED);
toggle.syncState();
searchActivated=false;
reload_fragment_data();
return true;
}
else if ((id == android.R.id.home) && (!searchActivated))
{
drawer.openDrawer(GravityCompat.START); // OPEN DRAWER
return true;
}
return super.onOptionsItemSelected(item);
}
am building a simple dialler to help me check my account balance but for some unknown reasons am getting some errors, i have a button on my xml which i have set its onclick element to sendMessage1 , but am getting error on my code with the phoneNum[1] telling me cannot reslove symbol phoneNum[1]. this is my code
/**Called when the user clicks the Send button */
public void sendMessage1(View view){
//example phoneNum[1] = "*556";
String encodedHarsh = Uri.encode("#");
startActivity(new Intent
("android.intent.action.DIAL",
Uri.parse("tel:"+ phoneNum[1]+ encodedHarsh)));
//Do something in response to button
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_mtn);
}
#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_mtn, 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);
}
You have to do it doing this :
String encodedHarsh = "*" + "556" + Uri.encode("#");
startActivity(new Intent("android.intent.action.CALL", Uri.parse("tel:" + encodedHarsh)));
Note, don't forget to add uses-permisions on manifest
how can I create a mainmenu in the actionbar and also an "options" menu that will open on hardware button click?
Like Whatsapp. There's an actionbar with avatar, name and and icon and if you press "menu" button, it will appear another menù with "Show contact, media, search" etc.
This is my actual code:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.calendar, 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_legend) {
// Open dialog
} else if(id == R.id.action_settings) {
startActivity(new Intent(this, SettingsActivity.class));
} else if(id == R.id.action_add) {
startActivity(new Intent(this, AddActivity.class));
}
return super.onOptionsItemSelected(item);
}
#Override
public boolean onKeyDown(int keycode, KeyEvent e) {
switch(keycode) {
case KeyEvent.KEYCODE_MENU:
// Here open the options menu
return true;
}
return super.onKeyDown(keycode, e);
}
When I created an activity it automatically added a back to main activity option in the action bar. It looks like those are the functions that do it:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.app_settings, 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);
}
Is there a way to make it go back using finish()? Right now it looks like it resets some values that are saved and I want to keep them. When I tried working with finish() it didn't do it but i'm not sure how to use it in the action bar.
This is simpler and it works perfect:
public class BackButtonExample extends Activity {
#SuppressLint("NewApi")
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.duahs);
ActionBar bar = getActionBar();
bar.setBackgroundDrawable(new ColorDrawable(Color.parseColor("#0B4C5F")));
bar.setDisplayHomeAsUpEnabled(true);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
this.finish();
return true;
default:
return super.onOptionsItemSelected(item);
}
}
}
Try this
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if(item.getItemId()==android.R.id.home {
finish();
return true; }
else{
return super.onOptionsItemSelected(item);
}
}
I added 3 menu items: Settings / About and Exit.
As you can see in the code, I made the Exit button to close the app, and I want that when I press the About button to open a new activity. How do I do that?
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.Toast;
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) {
return true;
} else if (id == R.id.Exit){
finish();
return true;
}
return super.onOptionsItemSelected(item);
}
}
if(id == R.id.action_masterz_yuris_about){
Intent openAboutActivityIntent = new Intent(this, MasterZYurisAboutActivity.class);
startActivity(openAboutActivityIntent);
}
try this code
#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;
} else if (id == R.id.Exit){
finish();
return true;
}else if (id == R.id.about){
Intent intent = new Intent(this, SecondActivity.class);
startActivity(intent);
return true;
}
return super.onOptionsItemSelected(item);
}
