问题
Hello there I am trying to implement a simple Android Bottom sheet and my used xml is as follow!
MY XML
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/main_content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<Button
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="Effects"
android:id="@+id/effects"
android:textStyle="italic"/>
<!--contains my layout for buttons, nested layout etc etc-->
</LinearLayout
<android.support.v4.widget.NestedScrollView
android:id="@+id/color_effects_bottom_sheet"
android:layout_width="match_parent"
android:layout_height="350dp"
android:clipToPadding="true"
app:behavior_hideable="true"
android:background="@android:color/holo_orange_light"
app:layout_behavior="android.support.design.widget.BottomSheetBehavior">
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="Please Set the Color Effects here!"
android:padding="16dp"
android:textSize="16sp"/>
</android.support.v4.widget.NestedScrollView>
The Code behind this XML is as Follow
Code Behind
public class MainActivity extends Activity {
//Variables for bottom sheets calls
private Button btn_effects;
private BottomSheetBehavior mBottomSheetBehavior;
private CoordinatorLayout coordinatorLayout;
////////////////////////////////////
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//locate coordinator layout
coordinatorLayout=(CoordinatorLayout)findViewById(R.id.main_content);
//locate bottom sheet
View color_bottomSheet = coordinatorLayout.findViewById( R.id.color_effects_bottom_sheet);
//View scene_bottomSheet = coordinatorLayout.findViewById( R.id.scenes_bottom_sheet);
//effects button
btn_effects=(Button)findViewById(R.id.effects);
//scenes button
btn_scenes=(Button)findViewById(R.id.scenes);
//settings button
btn_settings=(Button)findViewById(R.id.settings);
//bottom sheet behavior
mBottomSheetBehavior = BottomSheetBehavior.from(color_bottomSheet);
//effects button listener
btn_effects.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
mBottomSheetBehavior.setState(BottomSheetBehavior.STATE_EXPANDED);
}
});
}
}
The Problem
The problem is that when i try to run this code it crashes my App and throws this Exception all the time.
The Exception

Need
Basically I am trying to implement Bottom Sheets for the first time. I want to add multiple Bottom Sheets to learn how to use them in the Application.
My Activity is a Full Screen Activity with the following App Theme
android:theme="@android:style/Theme.DeviceDefault.NoActionBar.Fullscreen">
I want to use the Full Screen Activity and want to implement multiple Bottom Sheets on Button Click Listeners!
回答1:
As its stated in Your crashlog
Caused by: java.lang.IllegalArgumentException: You need to use a Theme.AppCompat theme (or descendant) with the design library change your app theme to one mentioned above
回答2:
Add below line to your app-gradle if using android studio:
compile 'com.android.support:design:23.4.0'
回答3:
<style name="Theme.AppCompat.Light.NoActionBar.FullScreen" parent="@style/Theme.AppCompat.Light">
<item name="windowNoTitle">true</item>
<item name="windowActionBar">false</item>
<item name="android:windowFullscreen">true</item>
<item name="android:windowContentOverlay">@null</item>
</style>
I have to set a Custom Style to use a full screen activity to use multiple Bottom Screen!
The Whole Code
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/main_content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<Button
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="Effects"
android:id="@+id/effects"
android:textStyle="italic"/>
<!--contains my layout for buttons, nested layout etc etc-->
</LinearLayout
<android.support.v4.widget.NestedScrollView
android:id="@+id/color_effects_bottom_sheet"
android:layout_width="match_parent"
android:layout_height="350dp"
android:clipToPadding="true"
app:behavior_hideable="true"
android:background="@android:color/holo_orange_light"
app:layout_behavior="android.support.design.widget.BottomSheetBehavior">
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="Please Set the Color Effects here!"
android:padding="16dp"
android:textSize="16sp"/>
</android.support.v4.widget.NestedScrollView>
<android.support.v4.widget.NestedScrollView
android:id="@+id/second_bottom_sheet"
android:layout_width="match_parent"
android:layout_height="350dp"
android:clipToPadding="true"
app:behavior_hideable="true"
android:background="@android:color/holo_orange_light"
app:layout_behavior="android.support.design.widget.BottomSheetBehavior">
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="Please Set the Scene Effects here!"
android:padding="16dp"
android:textSize="16sp"/>
</android.support.v4.widget.NestedScrollView>
</android.support.design.widget.CoordinatorLayout>
The thing is that one can invoke the second bottom sheet same as of the first bottom sheet.
My problem was to use full screen activity, and was using non AppCompat Theme and Activity. So I used a custom style themed activity and here it goes!
