How to disable/hide three-dot indicator(Option men

问题:

How to disable/hide three-dot indicator(Option menu indicator) on ICS handsets which does't have menu button. ?

I am running application as <uses-sdk android:minSdkVersion="5"/> in Manifest, code is compiled with 4.0. Three-dot indicator shows on every screen.

Example for preference activities i don't want show Three-dot indicator, since it does't have any menu options.

Adding android:targetSdkVersion="14" in manifest it works. However don't want hide/remove three dots button on all screens . Only in preference activities don't want to show this three dots button.

回答1:

Override onPrepareOptionsMenu() in the fragment of the preference with this:

@Override
public boolean onPrepareOptionsMenu(Menu menu) {
    MenuItem item= menu.findItem(R.id.menu_settings);
    item.setVisible(false);
    super.onPrepareOptionsMenu(menu);
    return true;
}

if you have more then one item set all the items visibility flag to false

and add the command setHasOptionsMenu(true); to the onCreate command

after you will set all the visibility of the items to false the menu will disappear

on activity, the only difference is the onPrepareOptionsMenu is boolean and you don't need to add the setHasOptionsMenu(true); command on the creation

I just deleted the method :

@Override
public boolean onCreateOptionsMenu(com.actionbarsherlock.view.Menu menu) {
    getSupportMenuInflater().inflate(R.menu.main, menu);
    return true;
}

then that three-dot-menu goes away (:

Hope it helps.

 @Override
 public boolean onCreateOptionsMenu(Menu menu) {
       return false;
 }

回答4:

There is no way to show/hide "three-dot" menu indicator for a single activity. You can hide this menu indicator only for entire app by specifying android:targetSdkVersion="14" (or above) in your manifest file.

However, this menu indicator is not showing on preferences activity if it extends from native android.preference.PreferenceActivity class. I have this scenario implemented in a few of my apps, and it works perfectly.

I assume you are using some custom preferences implementations which does not extends from PreferenceActivity. Android Dev Team suggests to always use PreferenceActivity for any preferences in your applications.

Way too late to the party here, I was trying to remove all my menu items and the 3-dots(option menu indicator), I did differently than the solution given here I am surprised that nobody had told it. There is a visibility tag that can be set to false and no changing of code in activity is required visibility=false does the trick

in res / menu /..

<item
    android:id="@+id/action_settings"
    android:orderInCategory="100"
    android:showAsAction="never"
    visibility=false
    android:title="@string/action_settings"/>

Following code worked for my app. Tried on Samsung Galaxy S4 (Android 4.3) and Nexus 4 (Android 4.2):

@Override
public boolean onPrepareOptionsMenu(Menu menu) {
    MenuItem item= menu.findItem(R.id.action_settings);
    item.setVisible(false);
    return true;
}

回答7:

override method and return false remember of not call super

 @Override
public boolean onCreateOptionsMenu(Menu menu) {
    return false;
}

回答8:

Remove this item in res / menu / main.xml

<item
    android:id="@+id/action_settings"
    android:orderInCategory="100"
    android:showAsAction="never"
    android:title="@string/action_settings"/>

In addition: do not add an item that has showAsAction="never"- this will avoid the dots from showing. If you have more items than can not be shown at once the dots will be there again (and they are items that are flagged ifRoom).

You can actually change the Android targetVersion thus forcing the 3-dot menu to either hide or show. You need to override onCreate of your Activity like this :

@Override
public void onCreate(Bundle savedInstanceState) {
    getApplicationInfo().targetSdkVersion = 10; // To enable the 3-dot menu call this code before super.OnCreate
    super.onCreate(savedInstanceState); 
}

@Override
public void onCreate(Bundle savedInstanceState) {
    getApplicationInfo().targetSdkVersion = 14; // To disable the 3-dot menu call this code before super.OnCreate
    super.onCreate(savedInstanceState); 
}

Tested on Android 4.x.x and Android 3.0

I just excluded the "onCreateOptionsMenu"-method:

@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_planos, menu);
    return true;
}

回答11:

Just want to improve @war_hero answer. If You wanna set the visibility on run time You can use oncreateoptions menu parameter like this

Menu overflow;

 @Override
public boolean onCreateOptionsMenu(Menu menu) {

    getMenuInflater().inflate(R.menu.mymenu, menu);
    this.overflow = menu;
    return super.onCreateOptionsMenu(menu);
}

and then make a function to show or hide any menu item according to the index. for e.g.

public void hideorShowMenuItems(boolean bool){
   overflow.getItem(1).setVisible(bool);
   overflow.getItem(2).setVisible(bool);
   overflow.getItem(3).setVisible(bool);
   overflow.getItem(4).setVisible(bool);
   overflow.getItem(5).setVisible(bool);
}

回答12:

Copy paste this code in main.xml in menu folder you just need to make the item android:visible="false"

    <?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/action_settings"
        android:orderInCategory="100"
        android:visible="false"
        android:title="@string/action_settings"
        app:showAsAction="never" />
</menu>

回答13:

for hiding 3 dots in actionbar/ toolbar

 public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.activity_dash_board_drawer, menu);
        return false;  //for visible 3 dots change to true, hiding false
    }

回答14:

Should be:

<item
    android:id="@+id/linearlayout_splash"
    android:orderInCategory="100"
    android:showAsAction="never"
    android:visible="false"
    android:title="@string/action_settings"/>

回答15:

If you simply want to hide the button, this solution is a bit of a hack but works across all versions of Android (using AppCompat) and doesn't affect your other menu items:

styles.xml

<style name="AppTheme" parent="Theme.AppCompat.Light">
    ...
    <item name="android:actionOverflowButtonStyle">@style/AppTheme.Overflow</item>
    <!-- If you're using AppCompat, instead use -->
    <item name="actionOverflowButtonStyle">@style/AppTheme.Overflow</item>
</style>

<style name="AppTheme" />
<style name="AppTheme.Overflow">
    <item name="android:src">@null</item>
</style>

If you want the Overflow button hidden only on some screens, you could make this an alternate theme (change AppTheme above to AppTheme.NoOverflow) that only certain activities use :

AndroidManifest.xml

<activity android:name=".NoOverflowActivity"
          android:theme="@style/AppTheme.NoOverflow" >

This effectively just makes the icon have no width and height. I rarely recommend opposing design guidelines but in my scenario we used dedicated hardware that did not properly report a menu button was present.

回答16:

If MainActivity is

public class MainActivity extends AppCompatActivity

In MainActivity Class, Remove the below 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.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();

    //noinspection SimplifiableIfStatement
    if (id == R.id.action_settings) {
        return true;
    }

    return super.onOptionsItemSelected(item);
}

回答17:

Do it like this.

@Override
public boolean onPrepareOptionsMenu(Menu menu) {
    // if nav drawer is opened, hide the action items
    boolean drawerOpen = mDrawerLayout.isDrawerOpen(leftDrawer);
    return (!drawerOpen);
}

I am checking if my navigation drawer is visible I will hide the menu and vice versa. You can use it according to you requirement. Hope this helps. Happy Coding. :)

回答18:

This is how I find a solution of mine. It maybe helpful.

@Override
public boolean onKeyDown(int keycode, KeyEvent event ) {
    //KEYCODE_MENU
 if(keycode == KeyEvent.KEYCODE_MENU){
 /* AlertDialog.Builder dialogBuilder 
  = new AlertDialog.Builder(this)
  .setMessage("Test")
  .setTitle("Menu dialog");
  dialogBuilder.create().show();*/
  return true;

//  finish();
 }
 return super.onKeyDown(keycode,event);  
}

回答19:

I just used

 @Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

Where R.menu.main is only an empty menu xml

<menu xmlns:android="http://schemas.android.com/apk/res/android" ></menu>
