AppBarLayout change offset programmatically

由 倾然丶 夕夏残阳落幕 提交于 2019-12-10 04:21:20
问题 How can I change the offset of the AppBarLayout programmatically? I want a certain offset to the AppBarLayout(partially expanded) when the Activity first loads, then the user could expand it more or collapse it. The current behaviour is that it's fully expanded when the Activity first loads. my.xml <android.support.design.widget.AppBarLayout android:id="@+id/app_bar_layout" android:layout_width="match_parent" android:layout_height="300dp" android:fitsSystemWindows="true" android:theme="@style

问题 As the title says, my FloatingActionButton has some weird lines coming out of it only on 4.4 or lower. On Lollipop it works fine. This is a picture of the issue: The play image doesn't have those lines in it. My xml: <android.support.design.widget.FloatingActionButton android:id="@+id/play" android:layout_width="48dp" android:layout_height="48dp" android:src="@drawable/ic_av_play_arrow" app:borderWidth="0dp" app:elevation="6dp" app:layout_anchor="@+id/image" app:layout_anchorGravity="center

(Collapsing)Toolbar title resets its position after Snackbar appearance

由 谁都会走 提交于 2019-12-09 18:14:01
问题 I have a layout with CollapsingToolbarLayout and CoordinatorLayout as root element. Whenever a Snackbar is shown in the activity the title of the toolbar resets its position to the default expanded title position of the CollapsingToolbar even if the toolbar is not (fully) expanded. The second picture shows that the title is fixed no matter if the toolbar expands or not. The result is the same when I call snackbar.show() in activity or fragment . My layout structure looks like this:

问题 As per Googles Material Guidelines: https://material.io/guidelines/components/text-fields.html#text-fields-layout TextInputLayout hint should be the same color as the Error message: However it is not like that and when I call setError("My error") only the underline and the error message show up in red. How can I change this behavior to account for Google's own guidelines? 回答1: here is how you can do it <android.support.design.widget.TextInputLayout android:padding="8dp" android:id="@+id

Icons in TabLayout

由 那年仲夏 提交于 2019-12-09 06:22:34
问题 I have a simple AppCompatActivity with one simple Toolbar (android.support.v7.widget.Toolbar), one Design-Library TabLayout and one ViewPager . Now I have in this case 4 fragments which are inside the viewpager and can be swiped from the sides. That works fine. But as soon as I use mTabLayout.setupWithViewPager(mViewPager); , the icons disappear but I can tab on the empty spaces which works fine. If I remove the line, the icons are visible again, the "swipe" works but if I tab to an icon,

Navigation Drawer statusbar

由 我怕爱的太早我们不能终老 提交于 2019-12-09 04:30:32
I'm having trouble making Navigation drawer over statusbar . I'm using new Design support library. In blogspot thay said: NavigationView takes care of the scrim protection of the status bar for you, ensuring that your NavigationView interacts with the status bar appropriately on API21+ devices. But it has no documentation so I'm very confused how to use Drawer to achieve desired effect. I tried inserting following attributes in my styles-v21: <item name="android:windowDrawsSystemBarBackgrounds">true</item> <item name="android:statusBarColor">@android:color/transparent</item> after this
