Android-Fragment 切換屬性動畫

getSupportFragmentManager()->能支持早期的設備, 所使用的是視圖動畫,不支持屬性動畫

getFragmentManager()->只能新的設備,只能支持屬性動畫,不支持視圖動畫

模擬3D切換效果例子:
MainActivity

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

    if (savedInstanceState == null) {
//添加MainFragment
getFragmentManager().beginTransaction().addToBackStack(null).add(R.id.fragment_container, new MainFragment()).commit();
}

}


public void onBackPressed() {

if (getFragmentManager().getBackStackEntryCount() > 0) {
getFragmentManager().popBackStack();
} else {
super.onBackPressed();
}
}

MainFragment

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

    View root = inflater.inflate(R.layout.fragment_main, null);

root.findViewById(R.id.btnGoNextPage).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
            getFragmentManager().beginTransaction()
                    .addToBackStack(null)
                    .setCustomAnimations(R.animator.enter, R.animator.exit, R.animator.pop_enter, R.animator.pop_exit)
                    .replace(R.id.fragment_container, new AnotherFragment())
                    .commit();
}
    });

    return root;
}

AnotherFragment

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

    View root = inflater.inflate(R.layout.fragment_another, null);

root.findViewById(R.id.btnGoBack).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
            getFragmentManager().popBackStack();
}
    });

    return root;
}
