java - 如何将 fragment 中的非默认构造函数更改为默认构造函数？

Question

代码:

public PlacePickerFragment() {
    this(null);
}
public PlacePickerFragment(Bundle args) {
    super(GraphPlace.class, R.layout.com_facebook_placepickerfragment, args);
    setPlacePickerSettingsFromBundle(args);
}

您好，我想从上面的代码中删除弃用警告，有没有办法将其更改为默认构造函数？

Answer 1

创建 fragment 时，使用 setArgument():

Bundle args = new Bundle();
// Construct your bundle here
Fragment mFragment = new PlacePickerFragment();
mFragment.setArguments(args);
mFragment.initialize();

并使用 fragment 的默认构造函数。您可能需要在设置参数后调用 setPlacePickerSettingsFromBundle()，如下所示:

public PlacePickerFragment() {
    super(GraphPlace.class, R.layout.com_facebook_placepickerfragment, args);
}

public void initialize() {
    Bundle args = getArguments();
    setPlacePickerSettingsFromBundle(args);
}
