android-theme

The app I was working on so far was working fine until I added a couple of new activities and tried applied some changes to the theme. The following is my styles.xml file. I looked into other results and added a parent to AppTheme as I was getting an error regarding AppCompat earlier. I also made AppTheme parent of NoActionBar. One thing I noticed was when I apply AppBarOverlay to Register User Activity it crashes and when I apply other it doesn't. Main Activity is crashing regardless. <resources> <!-- Base application theme. --> <style name="AppTheme" parent="Theme.AppCompat.Light

I have a very strange problem with my app. After updating to the newest versions of Support libraries I get this error: java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.app/com.example.app.MainActivity}: java.lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity. This is where the exception is thrown: public class MainActivity extends AppCompatActivity { … @Override protected void onCreate(Bundle savedInstanceState) { getWindow().requestFeature(Window.FEATURE_ACTION_BAR_OVERLAY); super.onCreate(savedInstanceState);/

I've implemented a simple search dialog that performs a custom search of the data within my app (Via a custom provider) as according to the guidelines here: http://developer.android.com/guide/topics/search/search-dialog.html The problem is that the search bar's colors and size (exceeds the height of the action bar, etc) do not work within the design of my app. I know how to create a theme in my styles.xml file, but I do not know how to target the Android search dialog and suggestions listView. Does anyone know how I can do this? After 13 hours spent on the question, it turns out it's not

I have finished making my app. Now, I want to reset all my editTexts to have the layout width as fill parent instead of wrap content. android:layout_width="fill_parent" while currently all my editTexts are android:layout_width="wrap_content" Is there any way i can do this in a style xml file, instead of individually in each layout?
