我有 BottomSheetDialogFragment ，它需要在展开状态下打开，并且应该在向下滑动时跳过折叠状态。

问题是，我有时会遇到意想不到的行为

为什么我有时会看到这样的观点？

下面是我的代码，

@Override
    public int getTheme() {
        if (Build.VERSION.SDK_INT > 21) {
            return R.style.BottomSheetDialogTheme;
        } else {
            return super.getTheme();
        }
    }

    @NonNull
    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {

        BottomSheetDialog dialog = (BottomSheetDialog) super.onCreateDialog(savedInstanceState);

        dialog.setOnShowListener((DialogInterface.OnShowListener) dialog1 -> {
            BottomSheetDialog d = (BottomSheetDialog) dialog1;
            FrameLayout bottomSheet = (FrameLayout) d.findViewById(com.google.android.material.R.id.design_bottom_sheet);
            if (bottomSheet != null) {
                BottomSheetBehavior.from(bottomSheet).setState(BottomSheetBehavior.STATE_EXPANDED);
                BottomSheetBehavior.from(bottomSheet).setSkipCollapsed(true);
                BottomSheetBehavior.from(bottomSheet).setFitToContents(true);
                BottomSheetBehavior.from(bottomSheet).setPeekHeight(1000);
            }
        });

        return dialog;
    }

相同的风格/主题是

     <style name="BottomSheetDialogTheme" parent="BaseBottomSheetDialog">
            <item name="android:statusBarColor" tools:targetApi="lollipop">@android:color/transparent
            </item>
        </style>
        <!-- set the rounded drawable as …

这是我的build.gradle

apply plugin: 'com.android.application'

android {
compileSdkVersion 23
buildToolsVersion "23.0.2"

defaultConfig {
    applicationId "com.arefin.lasttrykinvay"
    minSdkVersion 15
    targetSdkVersion 23
    versionCode 1
    versionName "1.0"
    multiDexEnabled true
}
buildTypes {
    release {
        minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}
repositories {
    flatDir {
       dirs 'libs'
    }
}


dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile(name:'kinvey-android-2.10.5', ext:'aar')
    compile 'com.android.support:appcompat-v7:23.1.1'
    compile google-http-client-1.19.0.jar 
    compile google-http-client-android-1.19.0.jar
    compile google-http-client-gson-1.19.0.jar 
    compile google-http-client-jackson2-1.19.0.jar 
    compile gson-2.1.jar guava-18.0.jar 
    compile jackson-core-2.1.3.jar 
    compile java-api-core-2.10.1.jar 
    compile java-api-core-2.10.5.jar 
    compile kinvey-android-2.10.5.aar
    testCompile 'junit:junit:4.12'
}

这是错误
