调用主活动中的碎片

Question

我为每个类别设置了不同的片段集，并希望在从抽屉中选择时显示它们

private static final String ARG_POSITION = "position";
private int position;
private LinearLayout layout;
private TextView icon;
public static WizardUniversalFragment newInstance(int position) {
WizardUniversalFragment f = new WizardUniversalFragment();
Bundle b = new Bundle();
b.putInt(ARG_POSITION, position);
f.setArguments(b);
return f;
}

我该如何解决这个问题？

Answer 1

您根据每个片段的位置调用它们。

根据你的代码，我已经理解了你的立场声明参数使用它来调用每个Fragment

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
position = getArguments().getInt(your_pos);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_wizard_universal,
container, false);
layout = (LinearLayout) rootView
.findViewById(R.id.Your_fragment);
icon = (TextView) rootView
.findViewById(R.id.Your_fragment_icon);
if (position == 0) {
layout.setBackgroundColor(ContextCompat.getColor(getContext(),
R.color.#));
layout.invalidate();
icon.setText(R.string.#);
} 
ViewCompat.setElevation(rootView, 50);
return rootView;
}

设置它，你就可以去了
