This library is the implementation of filter-concept posted on MaterialUp.com.
It makes animation of FloatingActionButton to BottomSheetDialog easy to implement.
Gradle
Step 1. Add the jCenter repository to your project-level build.gradle file
allprojects { repositories { jcenter() } }Step 2. Add the dependency to your app-level build.gradle file:
dependencies { compile 'com.allattentionhere:fabulousfilter:0.0.5' }Create a Fragment that extends AAH_FabulousFragment:
public class MySampleFabFragment extends AAH_FabulousFragment { public static MySampleFabFragment newInstance() { MySampleFabFragment f = new MySampleFabFragment(); return f; } @Override public void setupDialog(Dialog dialog, int style) { View contentView = View.inflate(getContext(), R.layout.filter_sample_view, null); RelativeLayout rl_content = (RelativeLayout) contentView.findViewById(R.id.rl_content); LinearLayout ll_buttons = (LinearLayout) contentView.findViewById(R.id.ll_buttons); contentView.findViewById(R.id.btn_close).setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { closeFilter("closed"); } }); //params to set setAnimationDuration(600); //optional; default 500ms setPeekHeight(300); // optional; default 400dp setCallbacks((Callbacks) getActivity()); //optional; to get back result setAnimationListener((AnimationListener) getActivity()); //optional; to get animation callbacks setViewgroupStatic(ll_buttons); // optional; layout to stick at bottom on slide setViewPager(vp_types); //optional; if you use viewpager that has scrollview setViewMain(rl_content); //necessary; main bottomsheet view setMainContentView(contentView); // necessary; call at end before super super.setupDialog(dialog, style); //call super at last } } Create view for the fragment which has parent element AAH_FilterView:
<com.allattentionhere.fabulousfilter.AAH_FilterView xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <RelativeLayout android:id="@+id/rl_content" android:layout_width="match_parent" android:layout_height="match_parent" android:layout_alignParentBottom="true" android:background="@color/orange" android:visibility="invisible" tools:ignore="MissingPrefix" tools:visibility="visible"> <LinearLayout android:id="@+id/ll_buttons" android:layout_width="match_parent" android:layout_height="56dp" android:layout_alignParentBottom="true" android:background="@color/brown" android:orientation="horizontal" android:weightSum="2"> </LinearLayout> </RelativeLayout> </com.allattentionhere.fabulousfilter.AAH_FilterView> Start the fragment on click of FloatingActionButton as below:
fab.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { MySampleFabFragment dialogFrag = MySampleFabFragment.newInstance(); dialogFrag.setParentFab(fab); dialogFrag.show(getSupportFragmentManager(), dialogFrag.getTag()); } }); This parameter specifies the ViewGroup of the bottom sheet to be shown after animation ends. It can be any ViewGroup(LinearLayout/FrameLayout etc):
setViewMain(relativelayout_content); This parameter speicfies the inflated view for the dialog:
setMainContentView(contentDialogView); This paramter sets animation duration of translate and scale animation in milliseconds:
setAnimationDuration(600); // default 500ms This parameter sets the peek height of the bottom sheet in dp:
setPeekHeight(300); // default 400dp This paramter is used to get callback from AAH_FabulousFragment to the component that called it:
setCallbacks((Callbacks) getActivity()); To use it, implement the callback in the calling component(Activity/Fragment etc), example:
public class MainSampleActivity extends AppCompatActivity implements AAH_FabulousFragment.Callbacks { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main_sample); } @Override public void onResult(Object result) { Log.d("k9res", "onResult: " + result.toString()); if (result.toString().equalsIgnoreCase("swiped_down")) { //do something or nothing } else { //handle result } } } This parameter is used to get animation callbacks.
setAnimationListener((AnimationListener) getActivity()); To use it, implement the AnimationListener in the calling component(Activity/Fragment etc), example:
public class MainSampleActivity extends AppCompatActivity implements AAH_FabulousFragment.AnimationListener { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main_sample); } @Override public void onOpenAnimationStart() { //do something on open animation start } @Override public void onOpenAnimationEnd() { //do something on open animation end } @Override public void onCloseAnimationStart() { //do something on close animation start } @Override public void onCloseAnimationEnd() { //do something on close animation start } } This parameter is used to make view in Bottom Sheet static when user slides it. It can be any ViewGroup(LinearLayout/FrameLayout etc):
setViewgroupStatic(linearlayout_buttons); This parameter is used to support scrolling in ViewPager as BottomSheetDialog does not support multiple views with scroll:
setViewPager(viewPager);
