@Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_bottom_sheet); View bottomSheet = findViewById(R.id.bottom_sheet); behavior = BottomSheetBehavior.from(bottomSheet); behavior.setBottomSheetCallback(new BottomSheetBehavior.BottomSheetCallback() { @Override public void onStateChanged(@NonNull View bottomSheet, int newState) { //这里是bottomSheet状态的改变 } @Override public void onSlide(@NonNull View bottomSheet, float slideOffset) { //这里是拖拽中的回调，根据slideOffset可以做一些动画 } }); } behavior_hideable对应代码 behavior.setHideable(false);behavior_peekHeight对应代码 behavior.setPeekHeight(50); setBottomSheetCallback可以监听回调的状态,onStateChanged监听状态的改变,onSlide是拖拽的回调,onStateChanged可以监听到的回调一共有5种: STATE_HIDDEN: 隐藏状态。默认是false，可通过app:behavior_hideable属性设置。 STATE_COLLAPSED: 折叠关闭状态。可通过app:behavior_peekHeight来设置显示的高度,peekHeight默认是0。 STATE_DRAGGING: 被拖拽状态 STATE_SETTLING: 拖拽松开之后到达终点位置（collapsed or expanded）前的状态。 STATE_EXPANDED: 完全展开的状态。BottomSheets控件配合NestedScrollView、RecyclerView使用效果会更好,合理的使用让APP逼格满满。 我们需要在按钮按钮上添加对BottomSheets的显示和隐藏 12345if(behavior.getState() == BottomSheetBehavior.STATE_EXPANDED) { behavior.setState(BottomSheetBehavior.STATE_COLLAPSED);}else { behavior.setState(BottomSheetBehavior.STATE_EXPANDED);} 效果如图: design24.2.1的BottomSheets和23.2.0的BottomSheet有很大的区别,design23.2.0的包中如果你使用了BottomSheet,可以在屏幕外任何位置上拉即可拉出来布局,在24.2.1中没有了这个效果。 BottomSheetDialogBottomSheetDialog应该是最实用的控件,也是使用率非常高的控件。它可以替代大多数网格显示和列表展示的dialog和popupwindow，默认宽度撑满，并且在BottomSheetDialog 区域中向下滑动也让对话框消失。 首先写一个dialog展示的xml，dialog中xml可以不用被CoordinatorLayout包裹，但是还是推荐实用推荐的滑动控件NestedScrollView1234567891011121314151617181920212223242526272829<?xml version=\"1.0\" encoding=\"utf-8\"?><android.support.v4.widget.NestedScrollView xmlns:android=\"http://schemas.android.com/apk/res/android\" android:layout_width=\"match_parent\" android:layout_height=\"match_parent\"> <LinearLayout android:layout_width=\"match_parent\" android:layout_height=\"match_parent\" android:orientation=\"vertical\"> <TextView android:onClick=\"doclick\" android:layout_width=\"match_parent\" android:layout_height=\"100dp\" android:background=\"@color/colorPrimary\" android:gravity=\"center\" android:text=\"啦啦啦啦啦啦啦啦啦\" android:textColor=\"@color/white\" android:textSize=\"18sp\"/> <ImageView android:onClick=\"doclick\" android:layout_width=\"match_parent\" android:layout_height=\"wrap_content\" android:scaleType=\"centerCrop\" android:src=\"@drawable/banner\"/> </LinearLayout></android.support.v4.widget.NestedScrollView> 编写java代码1234BottomSheetDialog dialog = new BottomSheetDialog(this);View view = getLayoutInflater().inflate(R.layout.dialog_bottom_sheet, null);dialog.setContentView(view);dialog.show(); 只需要四行我们就可以展示BottomSheets效果的dialog,高度为你设置的behavior_peekHeight或者默认高度，宽度撑满。在很多情况底部显示dialog的时候，都可以考虑实用BottomSheetDialog来实现。效果如图: BottomSheetDialogFragmentBottomSheetDialogFragment可以帮助我们实现全屏的BottomSheet展示效果。新建一个类继承BottomSheetDialogFragment xml使用BottomSheetDialog的布局样式,我们直接看java代码 1234567891011121314151617181920212223242526public class FullSheetDialogFragment extends BottomSheetDialogFragment { private BottomSheetBehavior mBehavior; @Override public Dialog onCreateDialog(Bundle savedInstanceState) { BottomSheetDialog dialog = (BottomSheetDialog) super.onCreateDialog(savedInstanceState); View view = View.inflate(getContext(), R.layout.dialog_bottom_sheet, null); dialog.setContentView(view); mBehavior = BottomSheetBehavior.from((View) view.getParent()); return dialog; } @Override public void onStart() { super.onStart(); //默认全屏展开 mBehavior.setState(BottomSheetBehavior.STATE_EXPANDED); } public void doclick(View v) { //点击任意布局关闭 mBehavior.setState(BottomSheetBehavior.STATE_HIDDEN); }} 调用BottomSheetDialogFragment展示 1new FullSheetDialogFragment().show(getSupportFragmentManager(), \"dialog\"); BottomSheetDialogFragment的效果跟BottomSheetDialog差不多,根据情况选择。效果如图: BottomSheetDialog就介绍到此，如果有错误请指出，谢谢。 参考：泡在网上的日子BottomSheets的使用 个人网站 歌吟有梦 itdais.com 更多内容可以关注我的公众号：丁军伟Dev（或者搜索DingAndroid）","categories":[],"tags":[{"name":"Android","slug":"Android","permalink":"http://itdais.com/tags/Android/"},{"name":"Gradle","slug":"Gradle","permalink":"http://itdais.com/tags/Gradle/"}]},{"title":"Android Studio运行时候报packageOfficialDebug错误","slug":"Android Studio运行时候报packageOfficialDebug错误","date":"2016-10-10T16:00:00.000Z","updated":"2016-10-13T02:00:31.032Z","comments":true,"path":"2016/10/11/Android Studio运行时候报packageOfficialDebug错误/","link":"","permalink":"http://itdais.com/2016/10/11/Android Studio运行时候报packageOfficialDebug错误/","excerpt":"","text":"Android Studio运行时候报packageOfficialDebug错误报错信息为 Error:A problem was found with the configuration of task’:watch:packageOfficialDebug’.File ‘…\\build\\intermediates\\res\\resources-official-debug-stripped.ap_’ specified for property ‘resourceFile’ does not exist. 解决方法一:这个大多数原因是开启了混淆造成的,关闭Debug模式下的混淆开关后重新编译即可,代码如下: 1234567891011121314buildTypes { release { buildConfigField("boolean", "LOG_DEBUG", "false") minifyEnabled true shrinkResources true proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } debug { minifyEnabled false shrinkResources false buildConfigField("boolean", "LOG_DEBUG", "true") proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } } minifyEnabled即以前的runProguard,用来控制是否混淆。 shrinkResources为true时自动去掉多余资源。 注：Gradle2.0以上的版本minifyEnabled字段为true时已经包含了shrinkResources,在代码优化时会自动去掉多余资源，所以在打正式包时也不需要设置shrinkResources字段。 解决方法二:Android Studio2.0以上有了Instant Run功能,很多情况下运行报错都跟Instant Run有关进入File –> Setting(Ctrl+Alt+S)找到InstantRun功能,把InstantRun功能关闭","categories":[],"tags":[{"name":"Android","slug":"Android","permalink":"http://itdais.com/tags/Android/"},{"name":"Gradle","slug":"Gradle","permalink":"http://itdais.com/tags/Gradle/"}]},{"title":"AS运行时异常(一)","slug":"AS运行时异常(一)","date":"2016-09-25T13:01:00.000Z","updated":"2016-09-05T13:35:22.539Z","comments":true,"path":"2016/09/25/AS运行时异常(一)/","link":"","permalink":"http://itdais.com/2016/09/25/AS运行时异常(一)/","excerpt":"","text":"从Github上下载了一个demo ,但是Android Studio一直运行不成功,爆出了下面的错误1234Error:(1, 1) A problem occurred evaluating project ':app'.> Failed to apply plugin [id 'com.android.application'] > Gradle version 2.10 is required.
