This is definitely a noob question. I've followed the instructions here http://developer.android.com/guide/topics/ui/settings.html#Activity and when I click on settings, nothing happens.
Here's what I have in MainActivity.java:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
PreferenceManager.setDefaultValues(this, R.xml.preferences, false);
}
Then I have a new java file called PrefsActivity.java
public class PrefsActivity extends PreferenceActivity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.preferences);
} }
Then I have res/xml/preferences.xml
<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
<CheckBoxPreference
android:key="face_up"
android:title="#string/face_up"
android:summary="#string/face_up_desc"
android:defaultValue="false" />
</PreferenceScreen>
I am trying to make it compatible with minsdk 7 if possible. What am I missing?
You need to open your activity when you click on your settings button. If your using an action bar, use something like this:
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.menu_settings:
Intent intent = new Intent(this, SettingsActivity.class);
startActivity(intent);
return true;
}
return super.onOptionsItemSelected(item);
}
In your main Activity
// Ensure the right menu is setup
#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;
}
// Start your settings activity when a menu item is selected
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (item.getItemId() == R.id.action_settings) {
Intent settingsIntent = new Intent(this, PrefsActivity.class);
startActivity(settingsIntent);
}
return super.onOptionsItemSelected(item);
}

I want to navigate to another Activity when click on the option menu item 'settings' from the menu bar. Nothing actual happens.I have checked similar issues posted here, but i can understand why this is not working for option menu.
see the code below:
Can't go to a new activity from selected option from option menu
<item
android:id="#+id/mySettings"
android:title="#string/action_settings" />
<item
android:id="#+id/logout"
android:title="log out" />
code:
public class Dashboard extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_dashboard);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.app_bar_menu,menu);
return super.onCreateOptionsMenu(menu);
}
public void openConfigure(){
Intent intent = new Intent(this,Configure.class);
this.startActivity(intent);
}
public boolean onContextItemSelected(MenuItem item) {
switch (item.getItemId()){
case R.id.mySettings:
openConfigure();
break;
default:
return super.onOptionsItemSelected(item);
}
return true;
}
Use onOptionsItemSelected instead of onContextItemSelected cause you are using OptionMenu not ContextMenu.
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()){
case R.id.mySettings:
openConfigure();
break;
}
return super.onOptionsItemSelected(item);
}
to select an options menu item, you have to override onOptionItemSelected() :
try below code
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()){
case R.id.mySettings:
openConfigure();
break;
}
return true;
}
I want to open a menu from a OnClickListener
without using the method onCreateOptionsMenu
My code:
toolbar.setNavigationIcon(R.drawable.week); //your icon
toolbar.setNavigationOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v ) {
}
});
Thanks in advance!
I think you want to show/hide a menu item based on actions from users. To do that you must use onCreateOptionsMenu and whenever you want to show/hide the menu item, then call invalidateOptionsMenu (this method will call onCreateOptionsMenu again).
boolean mShowMenu = false;
#Override
public boolean onCreateOptionsMenu(Menu menu)
{
getMenuInflater().inflate(R.menu.your_menu, menu);
MenuItem item = menu.findItem(R.id.your_menu_item);
item.setVisible(showMenu);
return true;
}
And in your code, when you want to show menu item.
toolbar.setNavigationIcon(R.drawable.week); //your icon
toolbar.setNavigationOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v ) {
mShowMenu = true;
invalidateOptionsMenu();
}
});
And give it a try.
You should need to create menu Interface in xml File Like this
<item
android:id="#+id/settings"
android:title="Setting"
app:showAsAction="never" />
<item
android:id="#+id/my_activity"
android:title="My Activity"
app:showAsAction="always"
android:icon="#android:drawable/btn_radio"/>
After that in the Java code of a particular class You need to create the code like this;
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.my_activity) {
Intent intent1 = new Intent(this,MyActivity.class);
this.startActivity(intent1);
return true;
}
if (id == R.id.settings) {
Toast.makeText(this, "Setting", Toast.LENGTH_LONG).show();
return true;
}
return super.onOptionsItemSelected(item);
}
Hopefully this may resolve your problem
I'm a new one in Android. I have some problems with showing menu. I don't see three dots in right corner in my screen. Please, help me to understand my mistake. THANK YOU A LOT!
Activity:
public class MainActivity extends AppCompatActivity {
private EditText numb1;
private EditText numb2;
private Button btn_sum;
private Button btn_extr;
private Button btn_mult;
private Button btn_div;
private TextView result;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
/*some code*/
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch(item.getItemId()) {
case R.id.reset:
numb1.setText("");
numb2.setText("");
break;
case R.id.exit:
fileList();
break;
}
return super.onOptionsItemSelected(item);
}
}
xml:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item android:id="#+id/reset"
android:title="#string/reset"
app:showAsAction="never"/>
<item android:id="#+id/exit"
android:title="#string/exit"
app:showAsAction="never"/>
</menu>
Menu Items are not showing on Action Bar
Check this answer
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="#+id/action_settings"
android:orderInCategory="100"
android:showAsAction="ifRoom|withText"
android:title="#string/action_option1"/>
<item
android:id="#+id/action_settings34"
android:orderInCategory="100"
android:showAsAction="ifRoom|withText"
android:title="#string/action_option2"/>
<item
android:id="#+id/action_settings3"
android:orderInCategory="100"
android:showAsAction="ifRoom|withText"
android:title="#string/action_option3"/>
</menu>
Use this code in your activity, but you should have action bar in it.
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.your_menu, menu);
return true;
}
if you run your application on oldest version of samsung or other the three DOTS is not appear on ActionBar
so try to click on Option Key on mobile
The solution to appear Three DOTS
call this method in your application class' onCreate method
private void makeActionOverflowMenuShown() {
//devices with hardware menu button (e.g. Samsung Note) don't show action overflow menu
try {
ViewConfiguration config = ViewConfiguration.get(this);
Field menuKeyField = ViewConfiguration.class.getDeclaredField("sHasPermanentMenuKey");
if (menuKeyField != null) {
menuKeyField.setAccessible(true);
menuKeyField.setBoolean(config, false);
}
} catch (Exception e) {
Log.d(TAG, e.getLocalizedMessage());
}
}
i am also new to android i guess u wrote onCreateOptionsMenu(Menu menu) inside on create
try this
public class MainActivity extends AppCompatActivity {
private EditText numb1;
private EditText numb2;
private Button btn_sum;
private Button btn_extr;
private Button btn_mult;
private Button btn_div;
private TextView result;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
/*some code*/
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.reset:
numb1.setText("");
numb2.setText("");
break;
case R.id.exit:
fileList();
break;
}
return super.onOptionsItemSelected(item);
}
}
You have done the minor mistake while creating the option menu .you should call the onCreateOptionsMenu() and onOptionsItemSelected() method outside the onCreate(Bundle savedInstanceState) method. you may check the following example :
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch(item.getItemId()) {
case R.id.reset:
break;
case R.id.exit:
fileList();
break;
}
return super.onOptionsItemSelected(item);
} }
Help me to understand my mistake - Sure
The Main culprit is in your menu XML file app:showAsAction="never" this line replace this line with app:showAsAction="ifRoom"
here showAsAction is set to never means you tell that don't show my menu in action bar if you replace with "ifRoom" means you said show my all menu in action bar and if there is space for all my menus
App share button on action bar is not working after i upload the app update on the play store as it works on the testing devices and also works on emulator.. ?
thank you in advance .
Circled part is not working after uploading on play store

popup_menu.xml:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"

android:id="#+id/menu_item_share"
android:title=""
app:showAsAction="always"
app:actionProviderClass="android.support.v7.widget.ShareActionProvider"
/>
</menu>
I had this issue as well once and after some digging inside the Logcat of Play store ready APK, I found the problem; it might apply to you as well.
The Issue was NoClassDefFoundError exception on ShareActionProvider !
Solution is to add this rule to your ProGuard file such as proguard-rules.pro and that's it!
-keep class android.support.v7.widget.ShareActionProvider { *; }
I'm trying to start up a preference fragment from a MenuItem and I'm having some trouble. I followed a tutorial on how to make a listPreference and then adapted it to my project, but it crashes the app.
This is the item in which is the launch point for the intenet to the prefFrag:
<item
android:id="#+id/action_settings"
android:orderInCategory="100"
android:showAsAction="never"
android:title="#string/settings"
android:onClick="prefStartup"/>
Here is the code that launches the intent in the main activity:
public void prefStartup(MenuItem item){
Intent intentSetPref = new Intent(getApplicationContext(), PrefActivity.class);
startActivityForResult(intentSetPref, 0);
}
Here are the two classes that help display the fragment (straight from the tutorial):
public class PrefActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
PrefFragment prefFragment = new PrefFragment();
FragmentManager fragmentManager = getFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.replace(android.R.id.content, prefFragment);
fragmentTransaction.commit();
}
}
public class PrefFragment extends PreferenceFragment {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.preference);
}
}
I'm not really sure why it would be breaking if the stuff is straight from the tutorial. In the tutorial though they just launch it from a regular button rather than a MenuItem.
I followed the same tutorial as you not long ago and managed to stumble my way through the same problem.
Instead of using your prefStartup() try the following in your main activity.
//Method for creating options menu
#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;
}
//Method for handling options menu selection
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
// action with ID action_settings was selected
case R.id.action_settings:
Intent intentSetPref = new Intent(getApplicationContext(), PrefActivity.class);
startActivityForResult(intentSetPref, 0);
break;
default:
break;
}
return true;
}
You can remove the android:onClick="prefStartup" from your menu xml as well.
