Can't inject view into custom class using RoboGuice
I started using RoboGuice in my project. I can easily inject views inside fragments and actions, but I have some problems with cusom views. I was getting a null ptr exception every time.
As per RoboGuice example, I did the same with my custom class:
TestActivity
@ContentView(R.layout.test_layout)
public class TestActivity extends RoboActivity {
@InjectView(R.id.testView_1) TestView testView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
}
TestView
public class TestView extends LinearLayout {
@InjectView(R.id.log_in_tab) View logInTab;
public TestView(Context context) {
super(context);
initView();
}
public TestView(Context context, AttributeSet attrs) {
super(context, attrs);
initView();
}
public TestView(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
initView();
}
@Override
public void onFinishInflate() {
super.onFinishInflate();
if (logInTab == null)
Toast.makeText(getContext(), "Still NULL", Toast.LENGTH_LONG).show();
else
Toast.makeText(getContext(), "Ok", Toast.LENGTH_LONG).show();
}
public void initView() {
inflate(getContext(), R.layout.login_view, this);
RoboGuice.injectMembers(getContext(), this);
}
}
The xml login is in pastebin here.
Testing scheme
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<view
android:layout_width="wrap_content"
android:layout_height="wrap_content"
class="hu.illion.kwindoo.view.test.TestView"
android:id="@+id/testView_1"/>
</LinearLayout>
Toast always says it is null. logInTab
Please help if you can.

I don't know why there are no code examples in it, but when I have to inject custom views, I use addViewMembers.
Hope this work for you:
public void initView() {
inflate(getContext(), R.layout.login_view, this);
RoboGuice.injectMembers(getContext(), this);
RoboGuice.getInjector(getContext()).injectViewMembers(this);
}
