Android Ratingbar Cannot render incorrectly above Lollipop in ViewPager

I made ratingbar inside a viewpager. When I slided the page, it's not problem, but when I not slide it, the ratingbar isnot showing and become black and blue. then when i let the app stay on like that in a minute, the app closed itself.
this is the code:
final int y =i;
nama[y] = new TextView(context);
nama[y].setLayoutParams(lhoriparams);
nama[y].setText(arrkonten.get(i)[0]);
rating[y] = new AppCompatRatingBar(context, null, android.R.attr.ratingBarStyleIndicator);
rating[y].setLayoutParams(ratingparams);
float f = Float.parseFloat(arrkonten.get(i)[1]);
rating[y].setRating(f);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
rating[y].setBackgroundTintList(ColorStateList.valueOf(Color.TRANSPARENT));
rating[y].setSecondaryProgressTintList(ColorStateList.valueOf(Color.TRANSPARENT));
rating[y].setProgressTintList(ColorStateList.valueOf(context.getResources().getColor(R.color.blue)));
rating[y].setElevation(10);
}
//rating[y].setStepSize(1/10);
rating[y].setNumStars(5);
rating[y].setIsIndicator(true);
linfo[i].addView(nama[y]);
linfo[i].addView(rating[y]);
please help me, Thx.

The last time I tried putting a RatingBar in my app, I had a lot of issues as well, I think it's device-related, on my device I would make it look ok, but then on some device if would appear similar to your screenshot.
I ended up creating a RatingBar on my own, it's quite easy actually, you create 2 pngs one for a selected star, and one for a not-selected star.
Then create something similar in a layout xml, like this:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:minWidth="100dp"
android:orientation="horizontal">
<ImageButton
android:id="#+id/one"
style="#style/RatingBar.Star"/>
<ImageButton
android:id="#+id/two"
style="#style/RatingBar.Star"/>
<ImageButton
android:id="#+id/three"
style="#style/RatingBar.Star"/>
<ImageButton
android:id="#+id/four"
style="#style/RatingBar.Star"/>
<ImageButton
android:id="#+id/five"
style="#style/RatingBar.Star"/>
</LinearLayout>
Where the style is:
<style name="RatingBar.Star" parent="EmptyParent">
<item name="android:layout_width">30dp</item>
<item name="android:layout_height">30dp</item>
<item name="android:layout_margin">10dp</item>
<item name="android:background">#drawable/star_not_selected</item>
<item name="android:scaleType">fitCenter</item>
<item name="android:onClick">onStarClicked</item>
</style>
Then you implement in your activity a method public void onStarClicked(View v) to catch clicks on stars on modify the background image from 0 to the clicked star.

I dont know what's wrong with the default RatingBar, but I have solved it, try use this library https://github.com/ome450901/SimpleRatingBar

MapFragment gets a dark overlay when used in DialogActivity

I'm trying to show a MapFragment of the Android Maps v2 API in an Activity with the #android:style/Theme.DeviceDefault.Light.Dialog.NoActionBar theme. This works fine. However, the map gets a dark overlay:
When I change the theme to #android:style/Theme.DeviceDefault.Light.NoActionBar, the map is shown as it should:
This is my xml layout file:
<?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="match_parent"
android:orientation="vertical" >
<fragment
android:id="#+id/mapfragment"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
class="com.google.android.gms.maps.MapFragment" />
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="HELLO"
android:textSize="#dimen/textsize_large" />
</LinearLayout>
What is happening here?

I got the same problem. After some research, I found two hacks :
Add this param for your theme in the styles.xml :
<item name="android:backgroundDimEnabled">false</item>
Bad part : it removes the black overlays behind the activity.
Set the z order on the top for the map object :
GoogleMapOptions googleMapsOptions = new GoogleMapOptions();
googleMapsOptions.zOrderOnTop( true );
MapFragment mapFragment = MapFragment.newInstance(googleMapsOptions);
Bad part : The map is above the Zoom control and MyLocation button.
Personnaly, I choose the first solution.
Hope this help !

For DialogFragment:
getDialog().getWindow().clearFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);

To add on to Audrel's solution, one can dynamically un-dim the dialog's window whenever the map is shown and dim it back when the map is gone (e.g. when your dialog has multiple pages, one of them is a map):
private float mDimAmount;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
WindowManager.LayoutParams params = getWindow().getAttributes();
mDimAmount = params.dimAmount; // remember original dim amount
...
}
private void undim() {
WindowManager.LayoutParams params = getWindow().getAttributes();
params.dimAmount = 0.0f;
getWindow().setAttributes(params);
}
private void dim() {
WindowManager.LayoutParams params = getWindow().getAttributes();
params.dimAmount = mDimAmount;
getWindow().setAttributes(params);
}
Still just another workaround rather than tackling the root cause...

Depending on what your purpose is for the map in the dialog, if you don't need any of the map controls, you can use liteMode in which just an image of the map is displayed with whatever location you load. It doesn't have this z-layer overlay problem.
You can add this to the MapView layout xml:
map:liteMode="true"
This worked for me, because I didn't want my map to be interactive anyway.
You can read the Google docs here: https://developers.google.com/maps/documentation/android-api/lite

Simply add this line to your style !
<item name="android:backgroundDimEnabled">false</item>
This is my style :
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/dark</item>
<item name="colorAccent">#color/colorAccent</item>
<item name="android:backgroundDimEnabled">false</item>
<item name="windowActionBar">false</item>
</style>

Dialog in full Screen

My question is i don't want to show transparent dialog in full screen
below is the code i used
dialog = new Dialog(this, R.style.CustomDialogTheme);
dialog.setContentView(R.layout.enterjoinseecode_dialog);
CustomDialog theme
<style name="CustomDialogTheme" parent="#android:style/Theme.Translucent.NoTitleBar">
<item name="android:windowIsTranslucent">true</item>
<item name="android:windowContentOverlay">#null</item>
<item name="android:windowIsFloating">true</item>
<item name="android:windowFullscreen">false</item>
</style>
Please some one helps me where i went wrong

Try this.Create your view for Dialog like below.
<RelativeLayout
android:layout_width="450dp"
android:layout_height="250dp"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:orientation="vertical" >
// Here you can add your component.
</RelativeLayout>
And set your dialog this view.
dialog = new Dialog(this, R.style.CustomDialogTheme);
dialog.setContentView(R.layout.enterjoinseecode_dialog);
That's it.Hope this will help you.

Create a activity with transparent background and for that particular activity define theme like this
<activity android:theme="#android:style/Theme.Dialog" />
And also if you want that activity to be exactly like dialog, then you can also use this
android:excludeFromRecents="true"
to remove it from the recent apps list.

some how with the following steps got the dialog with transparent effect with out full screen
No need of defining style "CustomDialogTheme" need to pass the theme argument for constructor as android.R.style.Theme_Translucent_NoTitleBar
and with in inflated xml just used background as android:background="#29000000" to make it transparent effect and layout_gravity property to position the dialog
if i use the above style CustomDialogTheme somehow its showing as a window instead of dialog because of that i applied direct theme to show that as dialog (not full screen)and to make it transparent effect with in xml i set the property background

How to display custom view in ActionBar?

I want to display custom search in actionbar (I'm using ActionBarSherlock for that).
I got that:
But I want make custom layout (edittext field) to occupy the entire available width.
I've implemented custom layout as suggested here.
There is my custom layout search.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
style="?attr/actionButtonStyle"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:layout_gravity="fill_horizontal"
android:focusable="true" >
<FrameLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical|fill_horizontal" >
<EditText
android:id="#+id/search_query"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="left|center"
android:background="#drawable/bg_search_edit_text"
android:imeOptions="actionSearch"
android:inputType="text" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="right|center_vertical"
android:src="#drawable/ic_search_arrow" />
</FrameLayout>
</LinearLayout>
And in MyActivity:
ActionBar actionBar = getSupportActionBar();
actionBar.setDisplayHomeAsUpEnabled(true);
actionBar.setDisplayShowCustomEnabled(true);
actionBar.setDisplayShowTitleEnabled(false);
actionBar.setIcon(R.drawable.ic_action_search);
LayoutInflater inflator = (LayoutInflater) this .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View v = inflator.inflate(R.layout.search, null);
actionBar.setCustomView(v);
How can I make custom layout to occupy all the available width of actionBar?
Help, please.

There is a trick for this. All you have to do is to use RelativeLayout instead of LinearLayout as the main container. It's important to have android:layout_gravity="fill_horizontal" set for it. That should do it.

I struggled with this myself, and tried Tomik's answer.
However, this didn't made the layout to full available width on start, only when you add something to the view.
You'll need to set the LayoutParams.FILL_PARENT when adding the view:
//I'm using actionbarsherlock, but it's the same.
LayoutParams layout = new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
getSupportActionBar().setCustomView(overlay, layout);
This way it completely fills the available space. (You may need to use Tomik's solution too).

This is how it worked for me (from above answers it was showing both default title and my custom view also).
ActionBar.LayoutParams layout = new ActionBar.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
// actionBar.setCustomView(view); //last view item must set to android:layout_alignParentRight="true" if few views are there
actionBar.setCustomView(view, layout); // layout param width=fill/match parent
actionBar.setDisplayShowCustomEnabled(true);//must other wise its not showing custom view.
What I noticed is that both setCustomView(view) and setCustomView(view,params) the view width=match/fill parent. setDisplayShowCustomEnabled (boolean showCustom)

The answers from Tomik and Peterdk work when you want your custom view to occupy the entire action bar, even hiding the native title.
But if you want your custom view to live side-by-side with the title (and fill all remaining space after the title is displayed), then may I refer you to the excellent answer from user Android-Developer here:
https://stackoverflow.com/a/16517395/614880
His code at bottom worked perfectly for me.

For example, you can define a layout file which contains a EditText element.
<?xml version="1.0" encoding="utf-8"?>
<EditText xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/searchfield"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:inputType="textFilter" >
</EditText>
you can do
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ActionBar actionBar = getActionBar();
// add the custom view to the action bar
actionBar.setCustomView(R.layout.actionbar_view);
EditText search = (EditText) actionBar.getCustomView().findViewById(R.id.searchfield);
search.setOnEditorActionListener(new OnEditorActionListener() {
#Override
public boolean onEditorAction(TextView v, int actionId,
KeyEvent event) {
Toast.makeText(MainActivity.this, "Search triggered",
Toast.LENGTH_LONG).show();
return false;
}
});
actionBar.setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM
| ActionBar.DISPLAY_SHOW_HOME);
}

There is an example in the launcher app of Android (that I've made a library out of it, here), inside the class that handles wallpapers-picking ("WallpaperPickerActivity") .
The example shows that you need to set a customized theme for this to work. Sadly, this worked for me only using the normal framework, and not the one of the support library.
Here're the themes:
styles.xml
<style name="Theme.WallpaperPicker" parent="Theme.WallpaperCropper">
<item name="android:windowBackground">#android:color/transparent</item>
<item name="android:colorBackgroundCacheHint">#null</item>
<item name="android:windowShowWallpaper">true</item>
</style>
<style name="Theme.WallpaperCropper" parent="#android:style/Theme.DeviceDefault">
<item name="android:actionBarStyle">#style/WallpaperCropperActionBar</item>
<item name="android:windowFullscreen">true</item>
<item name="android:windowActionBarOverlay">true</item>
</style>
<style name="WallpaperCropperActionBar" parent="#android:style/Widget.DeviceDefault.ActionBar">
<item name="android:displayOptions">showCustom</item>
<item name="android:background">#88000000</item>
</style>
value-v19/styles.xml
<style name="Theme.WallpaperCropper" parent="#android:style/Theme.DeviceDefault">
<item name="android:actionBarStyle">#style/WallpaperCropperActionBar</item>
<item name="android:windowFullscreen">true</item>
<item name="android:windowActionBarOverlay">true</item>
<item name="android:windowTranslucentNavigation">true</item>
</style>
<style name="Theme" parent="#android:style/Theme.DeviceDefault.Wallpaper.NoTitleBar">
<item name="android:windowTranslucentStatus">true</item>
<item name="android:windowTranslucentNavigation">true</item>
</style>
EDIT: there is a better way to do it, which works on the support library too. Just add this line of code instead of what I've written above:
getSupportActionBar().setDisplayShowCustomEnabled(true);

How can I get a Dialog style activity window to fill the screen?

I am using an activity with the dialog theme set, and I want it to be full screen. I tried all sorts of things, even going through the WindowManager to expand the window to full width and height manually, but nothing works.
Apparently, a dialog window (or an activity with the dialog theme) will only expand according to its contents, but even that doesn't always work. For instance, I show a progress bar circle which has width and height set to FILL_PARENT (so does its layout container), but still, the dialog wraps around the much smaller progress bar instead of filling the screen.
There must be a way of displaying something small inside a dialog window but have it expand to full screen size without its content resizing as well?

I found the solution:
In your activity which has the Theme.Dialog style set, do this:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.your_layout);
getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
}
It's important that you call Window.setLayout() after you call setContentView(), otherwise it won't work.

You may add this values to your style android:windowMinWidthMajor and android:windowMinWidthMinor
<style name="Theme_Dialog" parent="android:Theme.Holo.Dialog">
...
<item name="android:windowMinWidthMajor">97%</item>
<item name="android:windowMinWidthMinor">97%</item>
</style>

I just want to fill only 80% of the screen for that I did like this below
DisplayMetrics metrics = getResources().getDisplayMetrics();
int screenWidth = (int) (metrics.widthPixels * 0.80);
setContentView(R.layout.mylayout);
getWindow().setLayout(screenWidth, LayoutParams.WRAP_CONTENT); //set below the setContentview
it works only when I put the getwindow().setLayout... line below the setContentView(..)
thanks #Matthias

Wrap your dialog_custom_layout.xml into RelativeLayout instead of any other layout.That worked for me.

For Dialog
This may helpful for someone.
I want a dialog to take full width of screen. searched a lot but nothing found useful. Finally this worked for me:
mDialog.setContentView(R.layout.my_custom_dialog);
mDialog.getWindow().setBackgroundDrawable(null);
after adding this, my dialog appears in full width of screen.

This answer is a workaround for those who use "Theme.AppCompat.Dialog" or any other "Theme.AppCompat.Dialog" descendants like "Theme.AppCompat.Light.Dialog", "Theme.AppCompat.DayNight.Dialog", etc.
I myself has to use AppCompat dialog because i use AppCompatActivity as extends for all my activities. There will be a problem that make the dialog has padding on every sides(top, right, bottom and left) if we use the accepted answer.
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.your_layout);
getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
}
On your Activity's style, add these code
<style name="DialogActivityTheme" parent="Theme.AppCompat.Dialog">
<item name="windowNoTitle">true</item>
<item name="android:windowBackground">#null</item>
</style>
As you may notice, the problem that generate padding to our dialog is "android:windowBackground", so here i make the window background to null.

Set a minimum width at the top most layout.
android:minWidth="300dp"
For example:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android" android:minWidth="300dp">
<!-- Put remaining contents here -->
</LinearLayout>

Matthias' answer is mostly right but it's still not filling the entire screen as it has a small padding on each side (pointed out by #Holmes). In addition to his code, we could fix this by extending Theme.Dialog style and add some attributes like this.
<style name="MyDialog" parent="#android:style/Theme.Dialog">
<item name="android:windowBackground">#android:color/transparent</item>
<item name="android:windowNoTitle">true</item>
</style>
Then we simply declare Activity with theme set to MyDialog:
<activity
android:name=".FooActivity"
android:theme="#style/MyDialog" />

This would be helpful for someone like me. Create custom dialog style:
<style name="MyDialog" parent="Theme.AppCompat.Light.Dialog">
<item name="windowNoTitle">true</item>
<item name="android:windowFullscreen">true</item>
<item name="android:windowIsFloating">false</item>
</style>
In AndroidManifest.xml file set theme for wanted activity:
<activity
android:name=".CustomDialog"
...
android:theme="#style/MyDialog"/>
That is all, no need to call methods programaticaly.

In your manifest file where our activity is defined
<activity
android:name=".YourPopUpActivity"
android:theme="#android:style/Theme.Holo.Dialog" >
</activity>
without action bar
<activity android:name=".YourPopUpActivity"
android:theme="#android:style/Theme.Holo.Dialog.NoActionBar"/>
