Android app that downloads sfx and changes theme

This modifies the theme for that view and any child views, which is useful for altering theme color palettes in a specific portion of your interface.

The previous examples show how to apply a theme such as Theme. AppCompat that's supplied by the Android Support Library. But you'll usually want to customize the theme to fit your app's brand.

The best way to do so is to extend these styles from the support library and override some of the attributes, as described in the next section. Android provides a variety of ways to set attributes throughout your Android app.

For example, you can set attributes directly in a layout, you can apply a style to a view, you can apply a theme to a layout, and you can even set attributes programmatically. When choosing how to style your app, be mindful of Android's style hierarchy. In general, you should use themes and styles as much as possible for consistency. If you've specified the same attributes in multiple places, the list below determines which attributes are ultimately applied.

The list is ordered from highest precedence to lowest:. Figure 2. Styling from a span overrides styling from a textAppearance. For example, if you apply a theme to your app, along with a style to an individual View , the style attributes would override any matching theme attributes for that View. Note, however, that any theme attributes that aren't overridden by the style are still used. One limitation with styles is that you can apply only one style to a View.

Note, however, that if you define any text attributes directly on the View or in a style, those values would override the TextAppearance values. TextAppearance supports a subset of styling attributes that TextView offers. For the full attribute list, see TextAppearance. TextAppearance works at the character level and not the paragraph level, so attributes that affect the entire layout are not supported. When you create a project with Android Studio, it applies a material design theme to your app by default, as defined in your project's styles.

This AppTheme style extends a theme from the support library and includes overrides for color attributes that are used by key UI elements, such as the app bar and the floating action button if used. So you can quickly customize your app's color design by updating the provided colors. For example, your styles. So that's the file you should edit to change the colors. But before you start changing these colors, preview your colors with the Material Color Tool.

This tool helps you pick colors from the material palette and preview how they'll look in an app. And then you can override whatever other styles you want. For example, you can change the activity background color as follows:. For a list of attributes you can use in your theme, see the table of attributes at R. And when adding styles for the views in your layout, you can also find attributes by looking at the "XML attributes" table in the view class references.

For example, all views support XML attributes from the base View class. Most attributes are applied to specific types of views, and some apply to all views.

However, some theme attributes listed at R. Theme apply to the activity window, not the views in the layout. For example, windowBackground changes the window background and windowEnterTransition defines a transition animation to use when the activity starts for details, see Start an Activity with an Animation.

The Android Support Library also provides other attributes you can use to customize your theme extended from Theme. AppCompat such as the colorPrimary attribute shown above. These are best viewed in the library's attrs. That's used only for attributes from the Android framework.

There are also different themes available from the support library that you might want to extend instead of the ones shown above. The best place to see the available themes is the library's themes. If a new version of Android adds theme attributes that you want to use, you can add them to your theme while still being compatible with old versions. All you need is another styles. For example:. As such, you can avoid duplicating styles by beginning with a "base" theme and then extending it in your version-specific styles.

For example, to declare window transitions for Android 5. Now you can apply AppTheme in your manifest file and the system selects the styles available for each system version.

For more information about using alternative resources for different devices, read Providing Resources. Every widget in the framework and support library has a default style. For example, when you style your app using a theme from the support library, an instance of Button is styled using the Widget.

Button style. If you'd like to apply a different widget style to a button, then you can do so with the style attribute in your layout file. For example, the following applies the library's borderless button style:. And if you want to apply this style to all buttons, you can declare it in your theme's buttonStyle as follows:. You can also extend widget styles, just like extending any other style , and then apply your custom widget style in your layout or in your theme.

Thanks for your patience as I try to understand this. By "parent activity" I assume you mean the activity that started using startActivity the activity whose theme I want changed. No, by parent activity I mean some BaseActivity that all other activities in your app can extend.

OK so I guess this code would be in the constructor of the BaseActivity , so that it happens before the onCreate of the subclass activities? Show 1 more comment. Monty Monty 3, 8 8 gold badges 32 32 silver badges 60 60 bronze badges. This for when you want to user to select a theme at run time. No need to set in manifest — Monty. This works. I coupled it with a sharedpreferences config so the theme change is persistent. I was under the impression that one just has to call setTheme before calling setContentView — Someone Somewhere.

Save something, maybe an integer , using shared preferences. Then the next time you launch the app, you load the saved value and apply the appropriate theme.

In this answer, that is the switch position inside onCreate. Basically, it's the exact same thing as this answer, but I also saved a value which I check when the app launches and apply the necessary theme. At the time, I used shared prefs since that project used it a lot. Some projects have a database for settings, so you can also use that.

Even Firebase is fine, if you save settings in the cloud for example. Show 2 more comments. I had a similar problem and I solved in this way..

I edited it and removed the downvote. Instead of getApplication. BlackTheme ; use setTheme R. BlackTheme ; My code: in onCreate method: super.

I have a theme application which has PinkTheme styles. I have received theme Object of the theme package and try to setTheme of the preference application.

But its not working. Please help me that: how to set theme from others application to my current application programmatically. If you want to change settings in one application from another, then probably the easiest way to do it is to put a theme ID into an intent and send that intent to your MainActivity or to an IntentService where the receiving app can process the data. For example when the intent arrives, you can process it like you do a click event in your "onClick" logic.

Then in your activity, use getIntent. You would need to use the application's resources to load the theme. Here is an example where the package "com. See here for a working project on GitHub. This can lead to problems because all layouts, drawables, strings, etc. Therefore, you should avoid using a theme from another package and instead copy the resources and theme to your own project. How are we doing?
