Image Full Screen Blocked

[petitTrung]

Hi, thanks for your demo.

I have encountered another issue which happens only when i define a fullscreen image in CollapsingToolbarLayout.

Sometimes when i scroll up to see the content (RecyclerView) below the Image and then scroll down, the image is scrolled automatically until it fit to fullscreen. At that time, i can not re-scroll up anymore to see the the content below the Image.

You can refer to this Video : https://youtu.be/Qw-HLNj5ERU at the 00:25s when i keep trying scroll up (but no success) or at the end of this video.

For the FullScreen Image, layout_collapseMode was none or parallax
For AppBarLayout, the behavior was appbar_spring_behavior or appbar_fling_fix_behavior
Tested device : Nexus 5x, android 6.0.1

Could you fix this issue please.

Thanks.

Hi, you can try this in your activity_fling_app_bar_layout.xml (just replace The NestedScrollView by RecyclerView and define it in the holding activity)

and in your AppBarFlingFixActivity.java :

package loopeer.com.appbarlayout_spring_extension;

import android.os.Bundle;
import android.support.design.widget.FloatingActionButton;
import android.support.design.widget.Snackbar;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.LinearLayoutManager;
import android.support.v7.widget.RecyclerView;
import android.support.v7.widget.Toolbar;
import android.view.View;

import loopeer.com.appbarlayout_spring_extension.dummy.DummyContent;

public class AppBarFlingFixActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_fling_fix_app_bar_layout);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);

        FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
        fab.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
                        .setAction("Action", null).show();
            }
        });

        RecyclerView recyclerView = (RecyclerView) findViewById(R.id.recycler_view);
        recyclerView.setLayoutManager(new LinearLayoutManager(this));
        recyclerView.setAdapter(new MyItemRecyclerViewAdapter(DummyContent.ITEMS));
    }
}

Here is the Video : https://youtu.be/crLGtFr_CWY you can see at the 20s, 30s and 43s.
