I'm using a `DialogFragment' to display alert dialog. My requirement is to have a same theme for all the dialog fragment's in the appllicaiton across different versions of Android starting from 2.3. But I'm unable to apply theme. My code is
<style name="Dialog" parent="#android:style/Theme.Dialog">
<item name="android:windowTitleStyle">#style/MyOwnDialogTitle</item>
</style>
<style name="MyOwnDialogTitle" parent="android:Widget.TextView">
<item name="android:background">#android:color/darker_gray</item>
<item name="android:drawableRight">#android:drawable/ic_menu_add</item>
</style>
public class MyDialogFragment extends DialogFragment{
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
Context context = new ContextThemeWrapper(getActivity(), R.style.Dialog);
AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setTitle("Title");
builder.setMessage("Message");
builder.setPositiveButton("Ok", null);
return builder.create();
}
}
My output on 2.3 emulator is like
Please Help me out.
Thanks,
Sha.
Replace <style name="MyOwnDialogTitle" parent="android:Widget.TextView">
by
<style name="MyOwnDialogTitle" parent="#android:style/Widget.TextView">

Update 1 : After many attempts it's seems a general Issue after update IDE to version 3.1.2, till now there's only one solution which #mtak suggested although it is similar to the top menu options in the preview
Remove the line
tools:showIn="navigation_view"
from activity_main_drawer.xml and rebuild.
This solved the same problem for me.
Don't know why!!!
Problem solved in AS 3.1.3(8 June 2018) and reappeared again (16 June 2018)!!!
New temporary workaround:
Cut the line tools:showIn="navigation_view" from the menu file.
Close the menu file.
Reopen it and paste the line.
Go to design and see the menu as it should be.
If you close the menu file and reopen it the problem comes back!
Still no preview in Text.
You can try the following:
Run Build then try to see the preview again
Close the current layout,open another then reopen again
Because you extend AppCompatActivity, you need to make sure that in your styles.xml your AppTheme is a descendant of AppCompat
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
</style>
That worked for me while the accepted answer for not that helping.
I have found the solution. Remove these two tool lines and close/reopen:
xmlns:tools = "http://schemas.android.com/tools"
tools:showIn = "navigation_view"
Actually this problem is because you have extended your activity with AppComactActivity and your theme parent is not the Theme.AppCompat use this theme as your default in manifest.xml under application tag. your style should look like as
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
</style>
rebuilduing the project worked for me
Yeah as you can see above I get the mentioned Error. But I'm 100% sure the Activity's theme doesn't have an Action Bar. I'm trying to get de Toolbar working but every time I open the Activity the App crashes.

As you can see I set the AppTheme to NoActionBar and still get this Error:
This Activity already has an action bar supplied by the window decor. Do not request Window.FEATURE_SUPPORT_ACTION_BAR and set windowActionBar to false in your theme to use a Toolbar instead.
Does somebody know the answer?

I want to add toolbar in my android app but I am getting this error in my StudentDashboardActivity.java at run time after pushing my app on git. I could not find what's the problem behind of it.

Please tell me, how can I resolve this error?
Try to change style.xml to below given code
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<!-- Customize your theme here. -->
<item name="android:windowActionBar">false</item>
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
</style>
<style name="AppTheme.NoActionBar">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>
Declare the app Theme with windowActionBar as false in style.xml
<item name="windowActionBar">false</item>
if you have used any app support library for the theme need to include below line also
<item name="windowNoTitle">true</item>
I am using this code in styles.xml but my button background does not change.
Where i am doing wrong?
<style name="MyCustomTheme" parent="#android:style/Theme.Holo.Light">
<item name="android:actionBarStyle">#style/MyActionBar</item>
</style>
<style name="MyActionBar" parent="#android:style/Widget.Holo.Light.ActionBar">
<item name="android:homeAsUpIndicator">#drawable/actionbar_buttonbg</item>
<item name="android:background">#drawable/actionbar_bg</item>
</style>
Unfortunately you can not add a background to homeAsUpIndicator via styles.xml.
However you can do it programatically:
public void setHomeAsUpBackgroundResource(int resource) {
View abView = findViewById(R.id.action_bar);
if (abView != null && abView instanceof ViewGroup) {
ViewGroup vgAb = (ViewGroup) abView;
if (vgAb.getChildCount() > 0) {
View child = vgAb.getChildAt(0);
if (child != null && child instanceof ImageButton)
child.setBackgroundResource(resource);
}
}
}
It is hacky: it relies on two assumptions: this button is the first child of the action bar and is an instance of ImageButton.
Hi try use in style properties actionBarItemBackground good luck
<style name="MyActionBar" parent="#android:style/Widget.Holo.Light.ActionBar">
<item name="android:homeAsUpIndicator">#drawable/actionbar_buttonbg</item>
<item name="android:background">#drawable/actionbar_bg</item>
<item name="actionBarItemBackground">#color/backGroundHomeAsUp</item>
<item name="android:actionBarItemBackground">#color/backGroundHomeAsUp</item>
</style>
I am using themes in my android app to control which styles are applied to each element based on the currently selected theme in the manifest.
Within any one theme (of which there may be many) there are a number of styles which I would like to switch between at runtime. For example, i have a style which defines how text should normally look, and another style to define how that same piece of text should look when a code is entered incorrectly.
I cannot reference the #style directly since this is determined by the theme.
I have produced a sample app to illustrate my problem (note that the snippets below ommit some bits and pieces that aren't relevant)
Attrs.xml: (My custom resource references so my layouts don't reference styles directly)
<resources>
<attr name="theme_style_one" format="reference" />
<attr name="theme_style_two" format="reference" />
</resources>
Themes.xml: (Selects the appropriate style to apply based on the theme)
<resources xmlns:android="http://schemas.android.com/apk/res/android">
<style name="ThemeOne" parent="android:Theme">
<item name="theme_style_one">#style/blue</item>
<item name="theme_style_two">#style/red</item>
</style>
<style name="ThemeTwo" parent="android:Theme">
<item name="theme_style_one">#style/green</item>
<item name="theme_style_two">#style/red</item>
</style>
</resources>
Styles.xml (The styles themselves)
<resources xmlns:android="http://schemas.android.com/apk/res/android">
<style name="blue">
<item name="android:textColor">#color/color_blue</item>
</style>
<style name="red">
<item name="android:textColor">#color/color_red</item>
</style>
<style name="green">
<item name="android:textColor">#color/color_green</item>
</style>
</resources>
Colors.xml (Just some colours)
<resources>
<color name="color_blue">#0000FF</color>
<color name="color_green">#00FF00</color>
<color name="color_red">#FF0000</color>
</resources>
activity_main layout:
<TextView
android:id="#+id/txt_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:text="#string/hello_world"
style="?theme_style_one" />
activity_main's onCreate:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
TextView textView = (TextView)findViewById(R.id.txt_text);
textView.setTextAppearance(this, R.attr.theme_style_two);
}
What I would like to achieve is to change the TextView's style to "theme_style_two" programatically. The "SetTextAppearance" command has no effect. I cannot reference the #style/blue directly in this command, because if I changed the theme in the manifest an incorrect style would be applied.
Any help would be much appreciated!
