我试图将所有图标居中，我已经使用以下代码禁用了移位模式：

/**
 * This is done to remove the shift animation introduced by Android on the bottom navigation view
 * /sf/answers/2918332301/
 */
@SuppressLint("RestrictedApi")
public static void disableShiftMode(BottomNavigationView view) {
    BottomNavigationMenuView menuView = (BottomNavigationMenuView) view.getChildAt(0);
    try {
        Field shiftingMode = menuView.getClass().getDeclaredField("mShiftingMode");
        shiftingMode.setAccessible(true);
        shiftingMode.setBoolean(menuView, false);
        shiftingMode.setAccessible(false);
        for (int i = 0; i < menuView.getChildCount(); i++) {
            BottomNavigationItemView item = (BottomNavigationItemView) menuView.getChildAt(i);
            //noinspection RestrictedApi
            item.setShiftingMode(false);
            item.setPadding(0,15,0,0);
            // set once again checked value, so view will be updated
            //noinspection RestrictedApi
            item.setChecked(item.getItemData().isChecked());
        } …

这是我的build.gradle档案:

...
dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:22.0.0'
    compile 'com.android.support:cardview-v7:21.0.+'
    ...
}

在我添加之前:

compile 'com.android.support:design:22.2.0'

现在当我构建或重建我的项目时(我已经同步gradle了几次)我得到了这个错误:

我建立了一个基于Scrolling Activity(由android studio建议的预建活动)的项目,并面临一个奇怪的问题.请考虑以下情形:

我点击fab按钮转到另一个fragment但是当片段改变时,fab按钮不会消失!

谁能知道如何解决这个问题？

这是我Scrolling Activity添加到我的XML frameLayout:

        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

content_scrolling.xml :

所以我有一个应用程序,用户可以通过选择一组颜色来选择颜色RadioButtons,我已经使用ButtonTintXML属性为按钮着色,但显然这仅适用于API > 21/.

所以我的问题是,

如何更改RadioButtonsKitKat(API 19)及以下的颜色？

我已经从其他堆栈溢出问题中测试了一些方法,但到目前为止还没有一个有效.

我有NavigationView多个组,这是基于我需要隐藏和显示组的一些条件.我怎么能做到这一点.

我的示例NavigationView菜单

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">

 <group android:checkableBehavior="single"
        android:id="@+id/grp_employee"
        >

        <item
            android:id="@+id/help"
            android:checked="false"
            android:icon="@drawable/ic_help"
            android:title="@string/app_name" />

.......
</group>

<group android:checkableBehavior="single"
        android:id="@+id/grp_admin"
        >

        <item
            android:id="@+id/admin_help"
            android:checked="false"
            android:icon="@drawable/ic_help"
            android:title="@string/app_name" />

.......
</group>

<group> ... </group>

</menu>

这是我的NavigationView文件.我只想一次只显示一个组视图隐藏所有其他组.

我在我的一个应用布局中使用TextInputLayout.我的应用程序在Lollipop(5.1)及更高版本的用户设备上崩溃.以下是错误

我在每个支持设计小部件上都出错。像recyclerview，协调器布局等。每次，我添加一个正在显示的支持设计小部件。

java.lang.ClassNotFoundException: android.view.View$OnUnhandledKeyEventListener

在布局问题部分。我正在使用api 28.0.0-rc01，gradle 4.4 android 3.1.4。这是我的build.gradle（app）文件

    apply plugin: 'com.android.application'

    compileSdkVersion 28

    android:orientation="vertical">

    <android.support.design.widget.AppBarLayout
        android:layout_width="match_parent" …

我正在使用android支持设计小部件BottomNavigationView来制作我的底部导航项。这是工作的结果：

它有2个问题，第一个问题是没有在项目下显示标题，第二个问题是我要填充项目，我不想在导航上有可用空间，我只想让它们填充空间并在项目之间划分空间。

这是我的菜单代码：

    <?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">
    <item
        android:id="@+id/action_item1"
        android:icon="@drawable/phone"
        app:showAsAction="ifRoom"
        android:title="??????" />

    <item
        android:id="@+id/action_item2"
        android:icon="@mipmap/ic_history"
        app:showAsAction="ifRoom"
        android:title="????? ????" />

    <item
        android:id="@+id/action_item3"
        android:icon="@drawable/sabad"
        app:showAsAction="ifRoom"
        android:title="??? ????" />

    <item
        android:id="@+id/action_item4"
        android:icon="@drawable/market2"
        app:showAsAction="ifRoom"
        android:title="???????" />

</menu>

这是xml代码：

` <RelativeLayout
        android:id="@+id/activity_main"
        xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        xmlns:tools="http://schemas.android.com/tools"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        tools:context="com.truiton.bottomnavigation.MainActivity">

        <FrameLayout
            android:id="@+id/frame_layout"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_above="@+id/navigation"
            android:animateLayoutChanges="true">

        </FrameLayout>

        <android.support.design.widget.BottomNavigationView
            android:id="@+id/navigation"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_alignParentBottom="true"
            android:background="@color/colorPrimary"
            app:itemIconTint="#fff"
            app:itemTextColor="#F2F2F4"
            app:menu="@menu/bottom_navigation_items"/>
    </RelativeLayout>`

我该如何解决这个问题？

我在设计支持库中的BottomNavigationView遇到问题。我在activity_main.xml中使用它：

<android.support.design.widget.BottomNavigationView
        android:id="@+id/navigation"
        app:itemIconSize="16dp"
        app:labelVisibilityMode="labeled"
        app:itemTextColor="@color/white"
        app:itemIconTint="@color/white"
        app:itemBackground="@color/medium_purple"
        app:menu="@menu/main"
        android:layout_alignParentBottom="true"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"/>

膨胀该xml时，应用程序崩溃。异常的完整堆栈跟踪如下：
