Question

我遇到了问题：

我创建片段，然后使用TranactionManager.replace（）

将其添加到活动中

public class Main extends RoboActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        getFragmentManager().beginTransaction().replace(R.id.root, new     BaseFragment()).commit();
    }
}


public class BaseFragment extends RoboFragment {
    @InjectView(R.id.text)
    TextView textView;
    @InjectView(R.id.viewWithViews)
    ViewWithViews viewWithViews;
    public BaseFragment() {
       // Required empty public constructor
    }
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
        return inflater.inflate(R.layout.fragment_base, container, false);
    }
    @Override
    public void onViewCreated(View view, Bundle savedInstanceState) {
       super.onViewCreated(view, savedInstanceState);
       //text view and viewWithViews injected there
    }
}

这一点都是好的FragmentView创建并注入了所有视图。

但接下来：

public class ViewWithViews extends LinearLayout implements View.OnClickListener {
    @InjectView(R.id.child_text)
    TextView textView;
    private View button;

    @Inject
    private SharedPreferences sharedPreferences;

    public ViewWithViews(Context context) {
       super(context);
       init();
       onFinishInflate();
    }

    private void init() {
        inflate(getContext(), R.layout.child_view, this);
    }

    public ViewWithViews(Context context, AttributeSet attrs) {
       super(context, attrs);
       init();
    }

    public ViewWithViews(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        init();
    }

    @Override
    protected void onFinishInflate() {
        super.onFinishInflate(); // sharedPreferences are injected!
        this.button = findViewById(R.id.button);
        this.button.setOnClickListener(this);
        RoboGuice.injectMembers(getContext(), this); //force injection
        //still no views injected there

    }

    @Override
    public void onClick(View view) {
        System.out.println(view); // all possible events are passed, manual click. "textView" is not injected
    }
}

ViewWithViews中没有注入任何视图！

但是，如果将Fragment直接放在MainActivity R.layout.activity_main中，则会执行所有视图注入！我有点失望。这是一个错误，还是我做错了？

Answer 1

在onFinishInflate电话中：

RoboGuice.getInjector(context).injectViewMembers(this);

injectMembers只调用guice Injected对象，而不是android视图。

Answer 2

getSupportFragmentManager （）。beginTransaction（）。replace（R.id.main_fragment，new ReaderFragment（），＆＃34; fragment＆＃34;）。commit（）;

自定义视图中的Roboguice View Injection。
