I found the answer in this link:Status Bar Color not changing with Relative Layout as root element So it turns out we need remove the <item name=”android:statusBarColor”>@android:color/transparent</item> in styles.xml(v21). And it works just fine for me.
It looks like a margin/padding problem, try to set the cardUseCompatPadding attribute to true. E.g.: <android.support.v7.widget.CardView xmlns:android=”http://schemas.android.com/apk/res/android” xmlns:card_view=”http://schemas.android.com/apk/res-auto” android:layout_width=”match_parent” android:layout_height=”match_parent” android:layout_margin=”6dp” card_view:cardUseCompatPadding=”true” card_view:cardElevation=”4dp” card_view:cardCornerRadius=”3dp”> Explanation from Android doc : CardView adds additional padding to draw shadows on platforms before L. This may cause Cards to have different sizes between L and before L. If you … Read more
popupTheme Specifies the theme to use when inflating popup menus. By default, uses the same theme as the Toolbar itself. theme It is simply the theme of Toolbar.
Android M New in Android 6.0, Spinner now has the android:popupTheme parameter which allows you to set the theme used for the popup (dropdown). You can use it as so: <Spinner android:layout_height=”wrap_content” android:layout_width=”match_parent” android:popupTheme=”@android:style/ThemeOverlay.Material.Light” /> That will work on devices running API level 23+, but not on devices running a lower version of Android.

The recommended way to style the Toolbar for a Light.DarkActionBar clone would be to use Theme.AppCompat.Light.DarkActionbar as parent/app theme and add the following attributes to the style to hide the default ActionBar: <style name=”AppTheme” parent=”Theme.AppCompat.Light.DarkActionBar”> <item name=”windowActionBar”>false</item> <item name=”windowNoTitle”>true</item> </style> Then use the following as your Toolbar: <android.support.design.widget.AppBarLayout android:layout_width=”match_parent” android:layout_height=”wrap_content” android:theme=”@style/ThemeOverlay.AppCompat.Dark.ActionBar”> <android.support.v7.widget.Toolbar android:id=”@+id/toolbar” android:layout_width=”match_parent” android:layout_height=”?attr/actionBarSize” … Read more
After the new Support library v22.1, you can use something similar to this: @Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.menu_home, menu); Drawable drawable = menu.findItem(R.id.action_clear).getIcon(); drawable = DrawableCompat.wrap(drawable); DrawableCompat.setTint(drawable, ContextCompat.getColor(this,R.color.textColorPrimary)); menu.findItem(R.id.action_clear).setIcon(drawable); return true; }
As previous responses highlighted, it is bug. I recommend not to disable the specific lint warning project-wide, but for that method only. Annotate your method as follows: @SuppressLint(“RestrictedApi”) @Override public void setupDialog(Dialog dialog, int style) { super.setupDialog(dialog, style); //your code here }
Unless you try to extend the Android CardView class, you cannot customize that attribute from XML. Nonetheless, there is a way of obtaining that effect. Place a CardView inside another CardView and apply a transparent background to your outer CardView and remove its corner radius (“cornerRadios = 0dp”). Your inner CardView will have a cornerRadius … Read more
Finally I find the solution: instead of using android:colorControlHighlight directly in theme SelectableItemBackground, I should write another style: <style name=”SelectableItemTheme”> <item name=”colorControlHighlight”>@color/ripple_color</item> </style> Then: <style name=”SelectableItemBackground”> <item name=”android:theme”>@style/SelectableItemTheme</item> <item name=”android:background”>?attr/selectableItemBackground</item> </style> Finally add style=”@style/SelectableItemBackground” to View in layout.xml. UPDATED ON 2016/8/26 After N’s release, I found that sometimes we cannot use this method to set … Read more
