Could any one tell me, how to add Spinner to action bar in Fragment ?
I solved that issue by using below steps
Step - 1
Create xml file in Layout folder(Consider Layout name is spinnerwound.xml)
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="fill_parent"
android:background="#F79D27"
android:orientation="vertical">
<Spinner
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/spin"/>
</LinearLayout>
Step - 2
In Fragment Write like this
((ActionBarActivity)getActivity()).getSupportActionBar().setDisplayHomeAsUpEnabled(true);
((ActionBarActivity)getActivity()).getSupportActionBar().setDisplayShowCustomEnabled(true);
LayoutInflater inflator = (LayoutInflater) getActivity().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View vi = inflator.inflate(R.layout.spinnerwound, null);
Spinner s = (Spinner) vi.findViewById(R.id.spin);
spinnerlist = new ArrayList<String>();
spinnerlist.add(Item1);
spinnerlist.add(Item2);
spinneradapter = new ArrayAdapter<String>(getActivity(),android.R.layout.simple_dropdown_item_1line, spinnerlist);
s.setAdapter(spinneradapter);
((ActionBarActivity)getActivity()).getSupportActionBar().setCustomView(vi);
spinneradapter.notifyDataSetChanged();
s.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
//Do what ever you want
}

here are the java and xml files of the map fragment that i used
[maps app pic][1]
[1]: https://i.stack.imgur.com/xaBIR.png
I have a RecyclerView in MainActivity that shows a list of CardViews and that is working properly. A click on the CardView finishes the RecyclerView Activity and launches a Detail Activity that shows the clicked on CardView in a new RecyclerView list. The Detail Activity is used only to show that single CardView in a RecyclerView (I do this so I can use RecyclerView's ItemTouchHelper.SimpleCallback code on the CardView for easy left swipe for the user).
Here is the problem: I hit the left caret on the Detail Activity's Toolbar to return to the MainActivity. Then a click on the exact same CardView brings the user back to the Detail Activity. But this time only the background View (a border) is showing. The view of the CardView and its database data is completely missing.
The error appears to happen randomly. I can click to go from the MainActivity to the Detail Activity back and forth 5 times successfully and then on the sixth try, no CardView will show in the Detail Activity. Or I'll click two times successfully and then the third time, the CardView in the Detail Activity will not show. Note the left caret click in Detail Activity uses onBackPressed() so the Detail Activity finishes. So I don't think there should be any backstack issues. I also tried to adjust the xml height for the CardView to match_parent rather than wrap_content but no luck. The Detail Activity's ViewModel to Repository to Dao returns a List wrapped in LiveData. Perhaps there is an observer problem with the ViewModel, but I thought the observer gets removed/destroyed when the Detail Activity is destroyed? What am I missing here?

So if the data does not change then going back to the same DetailActivity will not refresh the View. The answer was to re-use the LiveData (rather than re-loading the LiveData again from the database) if the data has not changed. See the Android Developers Architecture Components guide for ViewModel, "Implement a ViewModel" section for the "loadUsers()" example that solved my problem: https://developer.android.com/topic/libraries/architecture/viewmodel.
I am new to Android Learning. I am trying to make a customAdapter that will display an image and a text in every row. In my Main_Activity, I have following code:`
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
String [] foods= {"Biryani","Matar Qeema","Chicken"};
ListAdapter faizisAdapter= new CustomAdapter(this,foods);
ListView faizisListView= (ListView)findViewById(R.id.faizisListView);
faizisListView.setAdapter(faizisAdapter);
faizisListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
String food= String.valueOf(parent.getItemAtPosition(position));
Toast.makeText(MainActivity.this,food,Toast.LENGTH_LONG).show();
}
});
}
}
Here is my CustomAdapter:
class CustomAdapter extends ArrayAdapter<String>{
CustomAdapter(Context context, String []foods)
{
super(context,R.layout.custom_row, foods);
}
public View getView(int position, #Nullable View convertView, #NonNull
ViewGroup parent) {
LayoutInflater faisizInflater = LayoutInflater.from(getContext());
View faizisView = faisizInflater.inflate(R.layout.custom_row, parent,
false);
String food = getItem(position);
TextView _foodsDisplay = (TextView)
faizisView.findViewById(R.id._foodDisplay);
ImageView _imageDisplay = (ImageView)
faizisView.findViewById(R.id._imageDisplay);
_imageDisplay.setImageResource(R.drawable.zaheer8423);
_foodsDisplay.setText(food);
return faizisView;
}
}
My Main_Activity_XML_FILE is:
<?xml version="1.0" encoding="utf-8"?>

/>
<TextView

android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</android.support.constraint.ConstraintLayout>
I haved saved image file in app/src/main/res/drawable/zaheer8423.jpg. I have connected my android device with android studio externally. When I run the app It opens and suddenly closes.
I have seen ways that use bitmap but I could not use them effectively, because I have very little knowledge about them.
Please help me here.
Looks like your Image size is big,You might need to scale down image something like this.
// Decode with inSampleSize
BitmapFactory.Options option = new BitmapFactory.Options();
option.inSampleSize = scale;
//You need to calculate appropriate sample size
Bitmap bitmap =
BitmapFactory.decodeResource(getContext().getResources(),R.drawable.zaheer8423,option);
imageDisplay.setImageBitmap(bitmap);
As its adapter you need to manage caching the bitmap and creating bitmap should be done in worker thread (Non Main thread i.e. UI Thread ) to avoid ANRs.
I'm sorry if this has been already answered but it's been a while and I'm still searching. Since the FAB has a behaviour class you can assign to it which will work with scrolling inside a coordinator layout, I was wondering if it was possible to include behaviour to make the FAB automatically get placed above an adview when it is visible similar to how it reacts to a snack bar. Thank you in advance.
Work Around!
I figured out a work around as I was just playing around some time back, even forgot about the question. Instead of putting my adview inside a container with the rest of my views I simply had to wrap the coordinator view in a Relative layout and set the coordinator layout above the adview ID. I'm sure this might not be the best way to do it.
So what I ended up having is this: NB My adview is set to visibility gone by default and I only set the visibility when the adrequest is complete
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"

</android.support.design.widget.AppBarLayout>
<include layout="#layout/content_main" />

android:layout_alignParentBottom="true"
android:visibility="gone"
app:adSize="SMART_BANNER"
app:adUnitId="#string/banner_ad_unit_id"
/>
</RelativeLayout>
The utils.FabBehavior_Main is the relative package class that contains the behaviour properties for the view, utils being the package. So in your own application you could have the name space com.myapp.utils.ScrollAwareFab which would have be like this:
public class ScrollAwareFab extends FloatingActionButton.Behavior {
public ScrollAwareFab(Context context, AttributeSet attrs) {
super();
}
#Override
public boolean onStartNestedScroll(CoordinatorLayout coordinatorLayout,
FloatingActionButton child, View directTargetChild, View target, int nestedScrollAxes) {
return nestedScrollAxes == ViewCompat.SCROLL_AXIS_VERTICAL ||
super.onStartNestedScroll(coordinatorLayout, child, directTargetChild, target,
nestedScrollAxes);
}
#Override
public void onNestedScroll(CoordinatorLayout coordinatorLayout, FloatingActionButton child,
View target, int dxConsumed, int dyConsumed, int dxUnconsumed, int dyUnconsumed) {
super.onNestedScroll(coordinatorLayout, child, target, dxConsumed, dyConsumed, dxUnconsumed,
dyUnconsumed);
if (dyConsumed > 0 && child.getVisibility() == View.VISIBLE) {
child.hide(new FloatingActionButton.OnVisibilityChangedListener() {
/**
* Called when a FloatingActionButton has been hidden
*
* #param fab the FloatingActionButton that was hidden.
*/
#Override
public void onHidden(FloatingActionButton fab) {
super.onShown(fab);
fab.setVisibility(View.INVISIBLE);
}
});
} else if (dyConsumed < 0 && child.getVisibility() != View.VISIBLE) {
child.show();
}
}
}
I'm painfully new to android and I've run into a wall.
I'm trying get a linear layout to function more like a button, with different actions for press and long press - The reason being so I can have 2 differently formatted text labels on each "button". Something along the lines of:
-------------------------
| 2nd | <- Label for long press (regular/smaller type)
| = | <- Label for regular press (bold/larger type)
-------------------------
The posts I've found explain how to receive a regular click on a linear layout (I use the onClick attribute in the layout XML). But I've had no luck with long press. I've tried to define a new onLongClick attribute for xml as described in Aleksander Gralak's answer here: Long press definition at XML layout, like android:onClick does . But had no such luck - it looks like it was intended for a text view, I tried changing it to linear layout but failed miserably.
Here is the object in question: Main.xml
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center"
android:clickable="true"
android:focusable="true"
android:background="#drawable/darkgrey_button"
android:onClick="equals" android:longClickable="true" android:id="equalsbutton"
android:focusableInTouchMode="false">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="2nd"
android:id="#+id/textView"
android:duplicateParentState="true"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text=" = "
android:id="#+id/textView1"
android:duplicateParentState="true"/>
</LinearLayout>
And Main.java
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
public void equals(View view) {
Context context = getApplicationContext();
CharSequence text = "Hello toast!";
int duration = Toast.LENGTH_SHORT;
Toast toast = Toast.makeText(context, text, duration);
toast.show();
}
Add an id to your layout.
<LinearLayout
android:id="#+id/my_button_layout"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
… >
In your Main.java
Get a reference to your LinearLayout and set a OnLongClickListener.
LinearLayout buttonLayout = (LinearLayout) findViewById(R.id.my_button_layout);
…
buttonLayout.setOnLongClickListener(new OnLongClickListener() {
#Override
public boolean onLongClick(View v) {
Toast.makeText(Main.this, "Long click!", Toast.LENGTH_SHORT).show();
return true;
}
});
