Suppose I have 3 Fragments, BaseFragment, and first fragment and second fragment.

I have implemented onResume() of BaseFragment and written a code to set the width and height like -

public void onResume() {



    super.onResume();

    WindowManager.LayoutParams params = getDialog().getWindow().getAttributes();

    params.width = RelativeLayout.LayoutParams.MATCH_PARENT;

    params.height = RelativeLayout.LayoutParams.WRAP_CONTENT;

    params.gravity = Gravity.CENTER;

    getDialog().getWindow().setAttributes(params);



    Log.d("upisdk", "basedialogfragment onresume()");

}

I have a first fragment, in which I want to set the width to, for example, 90% of the total width. I have implemented onResume() here also -

@Override

public void onResume() {

    super.onResume();



    WindowManager.LayoutParams params = getDialog().getWindow().getAttributes();

    params.width = (getWidth(getContext()) / 100) * 90;

    params.height = RelativeLayout.LayoutParams.WRAP_CONTENT;

    params.gravity = Gravity.CENTER;

    getDialog().getWindow().setAttributes(params);



    Log.d("upisdk", "onresume called on Changeddialogfragment");



}

And in SecondFragment I want to set to 80% I did this just like the above Fragment.

My onResume() is getting called twice. Once for BaseFragment and the other time for FirstFragment.

is this possible to call only first fragment onResume and not the parent one?

is this possible to call only first fragment onResume and not the parent one?

No, it isn't possible. This is what I get when I override onResume() in a Fragment and delete the line with super.onResume();

java.lang.RuntimeException: Unable to resume activity {com.example.mytestapp/com.example.mytestapp.MainActivity}: android.support.v4.app.SuperNotCalledException: Fragment MyTestFragment{4037a6b #0 id=0x7f090035 fragment} did not call through to super.onResume()

[...]

Caused by: android.support.v4.app.SuperNotCalledException: Fragment
MyTestFragment{4037a6b #0 id=0x7f090035 fragment} did not call
through to super.onResume()

But you can introduce a field protected int percent = x; in BaseFragment and let it have a different value x for each Fragment.

You can set this value in any method which gets called before onResume() and does not have to call through to its superclass implementation, e.g. in onCreateView().

Or you introduce your own method and call it from e.g. onCreate()

For example for the parent class:

protected void setPercent(){

    percent = 100;

}



@Override

public void onCreate(@Nullable Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    setPercent();

}

Whereas in the first Fragment, you write

@Override

protected void setPercent(){

    percent = 90;

}

Then the child Fragments don't need to override onResume() and the parent class is able to set the LayoutParams correctly:

public void onResume() {

    super.onResume();

    WindowManager.LayoutParams params = getDialog().getWindow().getAttributes();

    params.width = (getWidth(getContext()) * percent / 100);

    params.height = RelativeLayout.LayoutParams.WRAP_CONTENT;

    params.gravity = Gravity.CENTER;

    getDialog().getWindow().setAttributes(params);

}
