本文实例为大家分享了使用CoordinatorLayout实现底部弹出菜单的具体代码,供大家参考,具体内容如下
第一步:添加依赖:
代码语言:javascript复制compile "com.android.support:design:${project.properties.get("support")}"
第二步:布局引用:
代码语言:javascript复制<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#04827c"
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
//页面布局
</RelativeLayout
<include //引入菜单布局
android:id="@ id/au_bottom_sheet"
layout="@layout/view_audio_list"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:focusable="true"
app:behavior_hideable="true"
app:behavior_peekHeight="0dp"
app:layout_behavior="@string/bottom_sheet_behavior" /
</android.support.design.widget.CoordinatorLayout
第三步:使用:
代码语言:javascript复制//找到BottomSheetBehavior
BottomSheetBehavior behavior = BottomSheetBehavior.from(findViewById(R.id.au_bottom_sheet));
//设置弹出高度
behavior.setPeekHeight(WindowHeight / 2);
//默认隐藏
behavior.setState(BottomSheetBehavior.STATE_HIDDEN);
//添加消失监听
behavior.setBottomSheetCallback(bottomSheetCallback);
添加菜单消失监听:
代码语言:javascript复制 //状态监听,通过这个监听菜单是否消失
private BottomSheetBehavior.BottomSheetCallback bottomSheetCallback = new BottomSheetBehavior.BottomSheetCallback() {
@Override
public void onStateChanged(@NonNull View bottomSheet, int newState) {
if (newState == BottomSheetBehavior.STATE_HIDDEN) {
if (!isBehaviorShowing(behavior)) {
//菜单已经消失
}
}
}
@Override
public void onSlide(@NonNull View bottomSheet, float slideOffset) {
//滑动监听
}
};
判断是否可见:
代码语言:javascript复制 private Boolean isBehaviorShowing(BottomSheetBehavior behavior) {
return behavior.getState() == BottomSheetBehavior.STATE_COLLAPSED
|| behavior.getState() == BottomSheetBehavior.STATE_EXPANDED
|| behavior.getState() == BottomSheetBehavior.STATE_SETTLING;
}
收回菜单:
代码语言:javascript复制behavior.setState(BottomSheetBehavior.STATE_HIDDEN);
弹出菜单:
代码语言:javascript复制 behavior.setState(BottomSheetBehavior.STATE_COLLAPSED);
以上就是本文的全部内容,希望对大家的学习有所帮助。
