Must scroll up to see upper layout items

Must scroll up to see upper layout items - android

When activity launches first thing you see is recylerview instead upper items !
The first elements are a cardview including an imageview then a cardview including a radiobutton group. For visiting these items, you must scroll up the screen !
No errors , How can i solve this problem?
NOTE : my problem solves when i don't use of nestedScrollView but in this condition , the final cardview(icluding imageview) does not appear
this is xml code

You need to add the descendantFocusability in the first layout under the android.support.v4.widget.NestedScrollView like:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:descendantFocusability="blocksDescendants" >

I guess this is the solution for your problem. Check this link:
RecycleView steals focus when inside a NestedScrollView

The problem was solved by clearing cache and increasing heap size of the application. Also decreased the size of the logo in the navigation drawer

viewpager scrollview not working android

I'm integrating ViewPager and ScrollView on android but it doesn't seem to work. The ViewPager scroll works just fine but the ScrollView does not work at all on all the solutions I've tried. Below is my MainActivity class and xml layout.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.navigation_drawer);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
hostDescription = (TextView) findViewById(R.id.host_description);
hostDescription.setTypeface(quickSandRegular);
hostDescription.setTextColor(Color.BLACK);
scrollView = (ScrollView) findViewById(R.id.scroll);
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
View header=navigationView.getHeaderView(0);
ViewPager viewPager = (ViewPager) findViewById(R.id.view_pager);
ImageAdapter adapter = new ImageAdapter();
viewPager.setAdapter(adapter);
// set navigation font
Menu m = navigationView.getMenu();
for (int i=0;i<m.size();i++) {
MenuItem mi = m.getItem(i);
// apply font to subment
SubMenu subMenu = mi.getSubMenu();
if (subMenu!=null && subMenu.size() >0 ) {
for (int j=0; j <subMenu.size();j++) {
MenuItem subMenuItem = subMenu.getItem(j);
applyFontToMenuItem(subMenuItem);
}
}
applyFontToMenuItem(mi);
}
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();
}
});
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.setDrawerListener(toggle);
toggle.syncState();

ImageAdapter
class ImageAdapter extends PagerAdapter {
#Override
public int getCount() {
return IMAGES.length;
}
#Override
public boolean isViewFromObject(View view, Object object) {
return view == ((ImageView) object);
}
#Override
public Object instantiateItem(ViewGroup container, int position) {
ImageView imageView = new ImageView(getApplicationContext());
imageView.setImageResource(IMAGES[position]);
((ViewPager) container).addView(imageView, 0);
return imageView;
}
#Override
public void destroyItem(ViewGroup container, int position, Object object) {
((ViewPager) container).removeView((ImageView) object);
}
}

You need to implement ViewPager.OnPageChangeListener and write your logic in onPageScrollStateChanged
#Override
public void onPageScrollStateChanged(int state) {
ScrollView.requestDisallowInterceptTouchEvent(!(!lastPage && state == ViewPager.SCROLL_STATE_IDLE));
}
You need to write logic to find if you are on last page or not which is simple.

Solved the problem by customizing layout_height of the ViewPager. Below is the code:
<android.support.v4.view.ViewPager
android:id="#+id/view_pager2"
android:layout_width="match_parent"
android:layout_height="300dp"
android:paddingLeft="20dp"
android:paddingRight="20dp"/>
ViewPager viewPager = (ViewPager) findViewById(R.id.view_pager);
ImageAdapter adapter = new ImageAdapter();
viewPager.setAdapter(adapter);
viewPager.setClipToPadding(false);
viewPager.setPadding(70, 0, 70, 0);
class ImageAdapter extends PagerAdapter {
#Override
public int getCount() {
return IMAGES.length;
}
#Override
public boolean isViewFromObject(View view, Object object) {
return view == ((ImageView) object);
}
#Override
public Object instantiateItem(ViewGroup container, int position) {
ImageView imageView = new ImageView(getApplicationContext());
imageView.setImageResource(IMAGES[position]);
((ViewPager) container).addView(imageView, 0);
return imageView;
}
#Override
public void destroyItem(ViewGroup container, int position, Object object) {
((ViewPager) container).removeView((ImageView) object);
}
#Override
public void setPrimaryItem(ViewGroup container, int position, Object object) {
setPrimaryItem((View) container, position, object);
// lastPage = IMAGES[position]==object;
}
}

Viewpager With tabLayout and PagerTabStrip

I Experimented a bit in viewPager.
One viewpager with different FragmentAdapter.
For now the code works perfectly but I don't know if its the right way to do that.
For my Activity is this.

So I'am wondering if my code will do some errors in the future use?
I mean, will it have out of memory problem since i am using only one viewpager for different adapters.
And for the tab with pagerTabStrip Am i doing it right implemeting it both?
Thanks.

So you are setting a new FragmentPagerAdapter on each TabHost, thus creating 3 new fragments at runtime when the user clicks another tab. This might cause confusion to the user and if the framgments load heavy resources, greater memory consumption and further user annoyance.

Why does my ListView not show any content?

I'm trying to create a NavigationDrawer layout in Android, the main panel is working properly, and the drawer is a ListView. I've tried replacing the ListView with a TextView, which works fine. So, here's my code to add String content to the ListView.
Here is the relevant code.
private ArrayList<String> drawerContentStrings = new ArrayList<>();
private DrawerLayout homeLayout;
private ListView navigationDrawer;
private GridLayout homeContent;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.home_layout);
//homeContent = (GridLayout) findViewById(R.id.home_content);
//drawerContentStrings = getResources().getStringArray(R.array.navigation_content_strings);
//homeLayout = (DrawerLayout) findViewById(R.id.home_layout);
navigationDrawer = (ListView) findViewById(R.id.navigation_drawer);
System.out.println(drawerContentStrings.get(0));
ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(this, R.layout.nav_panel_item, drawerContentStrings);
navigationDrawer.setAdapter(arrayAdapter);
}
Here is the code for nav_panel_item (in the layout folder)
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/text1"
android:layout_width="100dp"
android:layout_height="100dp"
android:textColor="#000"
/>
And here is the code for the actual DrawerLayout: (idk if this is even relevant)
<GridLayout
android:id="#+id/home_content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:columnCount="2"
android:orientation="horizontal"
android:rowCount="2">
<Button
android:id="#+id/button1"
android:layout_gravity="left|top"
android:text="Button" />
<Button
android:id="#+id/button2"
android:layout_gravity="left|top"
android:text="Button" />
<Button
android:id="#+id/button3"
android:layout_gravity="left|top"
android:text="Button" />
<Button
android:id="#+id/button4"
android:layout_gravity="left|top"
android:text="Button" />
</GridLayout>
<ListView android:id="#+id/navigation_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:divider="#android:color/transparent"
android:dividerHeight="0dp"
android:background="#aff"/>
So, how do I make this work? Because I have no idea. Thanks!

In strings.xml, create an array list:
<string-array name="drawer_options">
<item>Test</item>
<item>Test</item>
<item>Test</item>
</string-array>
Create a new layout file, called activity_drawer.xml :
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent">
</FrameLayout>
<ListView
android:id="#+id/nav_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#fff"
android:choiceMode="singleChoice" />
</android.support.v4.widget.DrawerLayout>
Create a new Activity, called BaseActivity; it will help you to create a NavigationDrawer.
public class BaseActivity extends ActionBarActivity implements AdapterView.OnItemClickListener {
private ListView drawerList;
private DrawerLayout drawerLayout;
private ActionBarDrawerToggle mDrawerToggle;
private String[] options;
private TextView titleActionBar;
protected FrameLayout content;
protected void onCreateDrawer(final int layoutResID) {
setContentView(R.layout.activity_drawer);
content = (FrameLayout) findViewById(R.id.content_frame);
getLayoutInflater().inflate(layoutResID, content, true);
setupActionBar();
options = getResources()
.getStringArray(R.array.drawer_options);
drawerLayout =
(DrawerLayout) findViewById(R.id.drawer_layout);
drawerList = (ListView) findViewById(R.id.nav_drawer);
drawerList.setAdapter(new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1, options));
drawerList.setOnItemClickListener(this);
setupDrawer();
}
private void setupActionBar() {
getSupportActionBar().setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM);
getSupportActionBar().setCustomView(R.layout.action_bar);
titleActionBar = (TextView) findViewById(R.id.title_action_bar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
}
private void setupDrawer() {
mDrawerToggle = new ActionBarDrawerToggle(this, drawerLayout, R.string.drawer_open, R.string.drawer_close) {
public void onDrawerClosed(View view) {
super.onDrawerClosed(view);
titleActionBar.setText("AppName");
invalidateOptionsMenu();
}
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
titleActionBar.setText("Options");
invalidateOptionsMenu();
}
};
mDrawerToggle.setDrawerIndicatorEnabled(true);
drawerLayout.setDrawerListener(mDrawerToggle);
}
//get the position of the clicked list item
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
switch (position) {
case 2:
//For example, I redirect users to LoginActivity when they click on position 2 //(in this case, last item)
startActivity(new Intent(getApplicationContext(), LoginActivity.class));
drawerLayout.closeDrawer(drawerList);
break;
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.home_menu, menu);
return super.onCreateOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (mDrawerToggle.onOptionsItemSelected(item)) {
return true;
}
return super.onOptionsItemSelected(item);
}
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
mDrawerToggle.syncState();
}
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
mDrawerToggle.onConfigurationChanged(newConfig);
}
}
In MainActivity:
public class HomeActivity extends BaseActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
super.onCreateDrawer(R.layout.home_activity);
}
}
home_activity.xml is a "normal" layout file. Example:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:id="#+id/home_activity"
android:weightSum="1">
<TextView
android:gravity="center"
android:text="Hello"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:layout_marginTop="10dp"
android:layout_marginBottom="10dp"
android:padding="10dp"
android:textSize="20dp"
android:textStyle="bold"/>
</LinearLayout>
</ScrollView>

I think it is because your set GridLayout height to match_parent which takes all the screen.
Change your GridLayout height to wrap_content and check.
<GridLayout
android:id="#+id/home_content"
android:layout_width="match_parent"
android:layout_height="match_parent" // <---- change here to wrap_content and see.
android:columnCount="2"
android:orientation="horizontal"
android:rowCount="2">

Develop Reference

The Android operating system is a mobile operating system that was developed by Google (GOOGL?) to be primarily used for touchscreen devices, cell phones, and tablets.

Must scroll up to see upper layout items - android

You need to add the descendantFocusability in the first layout under the android.support.v4.widget.NestedScrollView like: <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="vertical" android:descendantFocusability="blocksDescendants" >

I guess this is the solution for your problem. Check this link: RecycleView steals focus when inside a NestedScrollView
