I am creating a custom spinner at runtime. after running the application the spinner style has successfully changed, but there are no more drop down when I click on the spinner. Any help would be appreciated.
Code in styles.xml
<style name="MyMaterialTheme.Base" parent="Theme.AppCompat.Light.NoActionBar">
<item name="android:windowNoTitle">true</item>
<item name="windowActionBar">false</item>
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
<item name="#attr/spinner_style">#style/spinner_style</item>
</style>
<style name="spinner_style" parent="#android:style/Theme.Holo.Light">
<item name="android:background">#drawable/gradiant_spinner</item>
<item name="android:layout_marginLeft">10dp</item>
<item name="android:layout_marginRight">10dp</item>
<item name="android:layout_marginBottom">10dp</item>
<item name="android:paddingLeft">8dp</item>
<item name="android:paddingTop">5dp</item>
<item name="android:paddingBottom">5dp</item>
<item name="android:popupBackground">#DFFFFFFF</item>
</style>
in attr.xml
<?xml version="1.0" encoding="utf-8"?>
<resources> <attr name="spinner_style" format="reference"/></resources>
in MyCustomSpinner:
public class MyCustomSpinner extends Spinner
{
public MyCustomSpinner(Context context) {
super(context, null, R.attr.spinner_style);
}
}
in Activity:
final MyCustomSpinner spinner = new MyCustomSpinner(context); //INITIALIZE THE SPINNER
spinner.setAdapter(new ArrayAdapter<String>(context, android.R.layout.simple_spinner_dropdown_item, lookupValues));
Try this:
final MyCustomSpinner spinner = new MyCustomSpinner(context);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(context, android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter, lookupValues));
adapter.notifyDataSetChanged();
if it don't work try to the keyword "final" before MyCustomSpinner spinner = ..

I want to make my Contextual Action Bar show a close icon other than the back arrow, but I'm not succeeding.
To do this, I have changed the actionModeCloseDrawable property in my styles.xml file: <item name="actionModeCloseDrawable">#drawable/ic_baseline_close_24</item>, but it is not working, as you can see in the image below:
This is my code at styles.xml:

How it's not working?
If I try this:
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (item.getItemId() == R.id.item_voz) {
if (mActionMode == null) {
//mActionMode = getActivity().startActionMode(mActionModeCallback);
mActionMode = ((AppCompatActivity)getActivity()).startSupportActionMode((androidx.appcompat.view.ActionMode.Callback) mActionModeCallback);
}
getActivity().invalidateOptionsMenu();
return true;
}
I'm having this error:
java.lang.ClassCastException:

This is my callback:

// ...
}

}
How about using a Toolbar? androidx.appcompat.widget.Toolbar has this method:
public void setNavigationIcon(#DrawableRes int resId)
Maybe activity.actionBar.setHomeAsUpIndicator(R.id.back)

create this in BaseActivity and call in onCreate method
public void updateTheme()
{
if (Utility.getTheme(getApplicationContext()))
{
setTheme(R.style.darkTheme);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
}
else
{
setTheme(R.style.lightTheme);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
}
}
Utility.java
public static void setTheme(Context context, boolean theme)
{
SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(context);
prefs.edit().putBoolean(context.getString(R.string.prefs_theme_key), theme).apply();
}
public static Boolean getTheme(Context context)
{
SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(context);
return prefs.getBoolean(context.getString(R.string.prefs_theme_key), false);
}
and in any Activity use any component to change theme, in this case Switch
Switch darkModeSwitch = findViewById(R.id.darkModeSwitch);
darkModeSwitch.setChecked(Utility.getTheme(this));
darkModeSwitch.setOnCheckedChangeListener((compoundButton, checked) ->
{
Utility.setTheme(getApplicationContext(), checked);
});

Please help me with it.
After reading comments, you need a contextual menu.
Inherit your PopupMenu from Widget.PopupMenu.
<style name="AppTheme.PopupMenu" parent="#android:style/Widget.PopupMenu">
<item name="android:popupBackground">#color/yourcolor</item>
</style>
I would suggest wrap your toolbar in AppBarLayout and in AppBarLayout theme set your menu style.
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/app_bar"
android:theme="#style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="#style/AppTheme.PopupOverlay"/>
</android.support.design.widget.AppBarLayout>
Here are styles.
<style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Light">
<!-- text color for toolbar and popup menu-->
<item name="android:textColorPrimary">#color/colorAccent</item>
<item name="popupMenuStyle">#style/AppTheme.PopupMenu</item>
<item name="android:popupMenuStyle">#style/AppTheme.PopupMenu</item>
</style>
<style name="AppTheme.PopupOverlay" parent="ThemeOverlay.AppCompat.Dark" />
<style name="AppTheme.PopupMenu" parent="#android:style/Widget.PopupMenu">
<!-- background color of popup menu-->
<item name="android:popupBackground">#color/colorBlack</item>
</style>
Finally, create your popup menu with AppBarLayout context.
AppBarLayout bar= (AppBarLayout) findViewById(R.id.app_bar);
PopupMenu p = new PopupMenu(bar.getContext(), findViewById(item.getItemId()));

When my button disabled i need remove text shadow effect and when button enable I need add this effect again.
selector_btn.xml
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:drawable="#drawable/btn_disabled"
android:state_enabled="false" />
<item
android:drawable="#drawable/btn_pressed"
android:state_pressed="true" />
<item
android:drawable="#drawable/btn_default" />
styles.xml
<style name="TextShadow">
<item name="android:textColor">#ffffffff</item>
<item name="android:shadowColor">#0D67B9</item>
<item name="android:shadowRadius">2.0</item>
<item name="android:shadowDy">-2.0</item>
</style>
<style name="BigButton" parent="TextShadow">
<item name="android:background">#drawable/selector_btn</item>
</style>
You have make 2 defferent styles for enable and disable condition and apply it to textview when it disable or vise versa ...
<style name="TextShadow_disable">
<item name="android:textColor">#ffffffff</item>
<item name="android:shadowColor">#0D67B9</item>
<item name="android:shadowRadius">0</item>
<item name="android:shadowDy">0</item>
</style>
<style name="TextShadow_enable">
<item name="android:textColor">#ffffffff</item>
<item name="android:shadowColor">#0D67B9</item>
<item name="android:shadowRadius">2.0</item>
<item name="android:shadowDy">-2.0</item>
</style>
textstyle = (TextView) findViewById(R.id.mytext);
textstyle.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
getTextStyle();
}
});
write down this method to check enable disable;
public void getTextStyle() {
if(textstyle.isEnabled()){
textstyle.setTextAppearance(this, R.style.TextShadow_enable);
}
else{
textstyle.setTextAppearance(this, R.style.TextShadow_disable);
}
}
I read many topics, but I didn't find answer of my problem. I'm trying to use android.R.style.Theme_Translucent_NoTitleBar or xml styles with
<style name="CustomDialogTheme" parent="#android:style/Theme.Dialog">
<item name="android:windowBackground">#color/transparent_white</item>
<item name="android:windowIsFloating">false</item>
<item name="android:windowNoTitle">true</item>
</style>
Even I have added
dialog.getWindow().setBackgroundDrawableResource(R.drawable.pixel);
where pixel is transparent drawable, but with no luck. I always have white border.
My code is below:
Dialog dialog = new Dialog(this,
android.R.style.Theme_Translucent_NoTitleBar);
dialog.getWindow().setBackgroundDrawableResource(R.drawable.pixel);
AlertDialog.Builder builder = new AlertDialog.Builder(this);
ListView modeList = new ListView(this);
String[] stringArray = new String[] { "aaa", "bbb" };
ArrayAdapter<String> modeAdapter = new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1, android.R.id.text1,
stringArray);
modeList.setAdapter(modeAdapter);
builder.setView(modeList);
dialog = builder.create();

The white border of a dialog is a 9patch image
and your background picture has to be an 9patch picture.
http://developer.android.com/guide/developing/tools/draw9patch.html
You can draw it yourself and make any border you like there.
you create your dialog like that
public AboutDialog(Context context) {
super(context,R.style.Theme_Dialog);
.......
and your style e.g.
<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="Theme" parent="android:Theme">
</style>
<style name="Theme.Dialog" parent="Theme">
<item name="android:layout_width">wrap_content</item>
<item name="android:layout_height">wrap_content</item>
<item name="android:windowIsFloating">true</item>
<item name="android:windowNoTitle">true</item>
<item name="android:windowContentOverlay">#null</item>
<item name="android:windowBackground">#drawable/bg</item> <------- your 9patch background picture
</style>
hope this helps abit
