I want to change actionbar icon size

Question

I tried to use this code

<item         android:id="@+id/male_button"         android:layout_width="46dp"         android:layout_height="56dp"         android:layout_gravity="right"         android:icon="@drawable/icon_male"         android:showAsAction="always"         android:title="i"/>     <item         android:id="@+id/female_button"         android:layout_width="46dp"         android:layout_height="56dp"         android:layout_gravity="right"         android:icon="@drawable/icon_female"         android:showAsAction="always"         android:title="i"/> 

and I changed android:layout_width="46dp" to android:layout_width="30dp" but I still have the same size the desired image is

and I now have this

How can I change the icons to be as the first picture ?

Answer 1

To reduce the space between actions icons, in your styles.xml you need to create a actionButtonStyle and referencing it your main theme (ex: "AppTheme").

1st step (put the two sentences):

<style name="AppTheme" parent="Theme.AppCompat.Light">   ...   <item name="android:actionButtonStyle">@style/myActionButtonStyle</item>   <item name="actionButtonStyle">@style/myActionButtonStyle</item>   ... </style> 

2nd step (the parameter "android:width" is the great secret):

<style name="myActionButtonStyle" parent="Widget.AppCompat.ActionButton">     <item name="android:minWidth">30dp</item>     <item name="android:maxWidth">48dp</item>     <item name="android:width">38dp</item> </style> 

enjoy it

Answer 2

private String[] tabnames; final int[] ICONS = new int[] {         R.drawable.a,         R.drawable.b,         R.drawable.c,} tabnames = getResources().getStringArray(R.array.tabnames); 

Those are the arrays made up here and in res/values/strings of your drawable names and your tab names

actionBar = getActionBar();     for (int i=0; i < tabnames.length; i++)     { 

Every time we get a tabname we add an icon for it

        Drawable dr = getResources().getDrawable(ICONS[i]);         Bitmap bitmap = ((BitmapDrawable) dr).getBitmap();         Drawable d = new BitmapDrawable(getResources(),          Bitmap.createScaledBitmap(bitmap, 50, 50, true)); 

Then we change get icon from array and make it a drawable with whatever size we want and add it to the actionbar.

    actionBar.addTab(actionBar.newTab().setText(tabnames[i])                              .setIcon(d)                              .setTabListener(this));     }
