片段中的操作栏-平板电脑和手机

Question

I am creating an App where I am using Fragments so as to attain UI flexibility.

In the Phone Portrait and Landscape mode the Fragmnets Appears like this :

In Tablets Portrait and Landscape Mode it Appears like this :

My main concern is ACTION BAR. I want to hide action bar only in case of SMARTPHONE in LANDSCAPE mode where FRAGMENT B appears Full Screen. I want to display the Action Bar in all other cases as I have shown in the Images.

I have searched whole stack overflow but did not find any solution. Can any one help me? Thanks in advance.

Answer 1

To solve this, there are 2 things you need to do:

1. Check if your device is a smartphone or tablet.

Create a new resources folder called values-sw600dp inside your res folder. (This only works for Android versions before 3.2, for previous versions create a values-xlarge folder)

Then here we create a file and set the following value:

<resources>
    <bool name="isTablet">true</bool>
</resources>

Then, in the standard value file (as res/values/), you set such boolean to false:

false

Now you can check if you are running in a tablet size device:

boolean tabletSize = getResources().getBoolean(R.bool.isTablet);
if (tabletSize) {
// do a
} else {
// do b
}

2. In case of being a smartphone, check orientation and hide action bar.

In your onCreateView method in your fragmentB after checking if you are using a smartphone or tablet (using your-new-resource-file.xml) we have to check the orientation. If the orientation is LANDSCAPE, then we hide the actionbar.

 boolean tabletSize = getResources().getBoolean(R.bool.isTablet);
if (!tabletSize) 
{
  //Lets check orientation
  if(getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE)
  {
      getActivity().getActionBar().hide(); //getSupportActionBar().hide() if using appcompat
  }
}

Hope it helps

I have used this codes to check if we are in SMARTPHONE or TABLET :

// Function to check if we are inside Phone or Tablet
public static boolean isTablet(Context context) {

    Boolean tablet = (context.getResources().getConfiguration().screenLayout & Configuration.SCREENLAYOUT_SIZE_MASK) >= Configuration.SCREENLAYOUT_SIZE_LARGE;

    return tablet;

    /* Returns TRUE if we are in TABLET
     * 
     * Returns FALSE if we in PHONE
     * 
     * 
     * */
}

Then after if i am inside the phone : I have used following code to check my screen orientation:

if(getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE)
{
  getActivity().getActionBar().hide(); //getSupportActionBar().hide() if using appcompat Library
}else{
  getActivity().getActionBar().show(); 
}
