我目前正在开发一款Android应用,我使用的是FloatingActionButton。我想使用快速拨号进行多项操作,按照谷歌在Android设计上的this页面中所描述的那样旋转/跳出操作按钮,或者可以在早期版本的Keep应用程序中看到(抱歉,但我只能发布一个链接)。我正在使用Android设计支持库专门版本23.1.1(com.android.support:design:23.1.1)。我已经使用Google进行了搜索并查看了FloatingActionButton的参考资料,但无法找到有关快速拨号的任何内容。
我想知道是否有办法使用默认的FloatingActionButton轻松实现这一点,或者我是否必须手动编程所有过渡/动画?
此外,我希望按钮旁边有小标签,如果可能的话,描述动作。
提前谢谢!

我在这里加上我的2美分,因为这是我在Googling之后登陆的地方。
我希望帮助像我这样的人来得太晚。
首先,解决方案来自here,所以不是我的。我只是尝试过它很好用。所以我想我会在一个帖子中与你分享,而不是从那里挖掘代码。
该解决方案使用com.android.support:design:25.3.1
库,因此请务必将其添加到build.gradle,并且需要API 21以上版本。
坏消息是,它由几个小动作组成:5个动画师,5个绘图加上图标和布局,当然还有代码,好消息是它可以正常工作,高度可定制,不会不需要在MainActivity之外进行任何编码。
一些注意事项:
结果如下:
所以,成分:

fab.xml
。所有工厂都在这里宣布。在前3 android:src
上将ImageButtons
替换为您自己的图标。
<?xml version="1.0" encoding="utf-8"?>
<merge xmlns:android="http://schemas.android.com/apk/res/android">
<RelativeLayout
android:id="@+id/fab_container"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="@dimen/activity_vertical_margin"
android:layout_marginEnd="@dimen/activity_horizontal_margin"
android:clipChildren="false" >
<!-- Please note that the @id are defined the first time they're referenced from top to bottom -->
<ImageButton
android:id="@+id/fab_action_3"
style="@style/FloatingActionButton.Mini"
android:src="@drawable/ic_volume_up_white_24dp"
android:layout_above="@+id/fab_action_2"
android:layout_alignEnd="@+id/fab"
android:contentDescription="@null"
android:backgroundTint="@color/sa_gray"
android:width="24dp"
android:height="24dp"
android:onClick="fabAction3" />
<ImageButton
android:id="@id/fab_action_2"

android:src="@drawable/ic_credit_card_white_24dp"

android:onClick="fabAction1" />
<ImageButton
android:id="@id/fab"
style="@style/FloatingActionButton"
android:src="@mipmap/ic_add_w"
android:layout_alignParentEnd="true"
android:layout_alignParentBottom="true"
android:contentDescription="@null"
android:visibility="visible"
android:layout_marginTop="8dp" />
</RelativeLayout>
</merge>
最后。
a)一些声明:
private static final String TAG = "Floating Action Button";
private static final String TRANSLATION_Y = "translationY";
private ImageButton fab;
private boolean expanded = false;
private View fabAction1;
private View fabAction2;
private View fabAction3;
private float offset1;
private float offset2;
private float offset3;
b)删除MainActivity
onCreate
上的常用晶圆厂代码:
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
.setAction("Action", null).show();
}
});
并将其替换为:
final ViewGroup fabContainer = (ViewGroup) findViewById(R.id.fab_container);
fab = (ImageButton) findViewById(R.id.fab);
fabAction1 = findViewById(R.id.fab_action_1);
// insert onClickListener here
fabAction2 = findViewById(R.id.fab_action_2);
// insert onClickListener here
fabAction3 = findViewById(R.id.fab_action_3);
// insert onClickListener here
fab.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
expanded = !expanded;
if (expanded) {
expandFab();
} else {
collapseFab();
}
}
});
fabContainer.getViewTreeObserver().addOnPreDrawListener(new ViewTreeObserver.OnPreDrawListener() {
@Override
public boolean onPreDraw() {
fabContainer.getViewTreeObserver().removeOnPreDrawListener(this);
offset1 = fab.getY() - fabAction1.getY();
fabAction1.setTranslationY(offset1);
offset2 = fab.getY() - fabAction2.getY();
fabAction2.setTranslationY(offset2);
offset3 = fab.getY() - fabAction3.getY();
fabAction3.setTranslationY(offset3);
return true;
}
});
c)在MainActivity
上添加支持函数(主要是动画代码和3个小型工厂的onClick
方法):
private void collapseFab() {
fab.setImageResource(R.drawable.animated_minus);
AnimatorSet animatorSet = new AnimatorSet();
animatorSet.playTogether(createCollapseAnimator(fabAction1, offset1),
createCollapseAnimator(fabAction2, offset2),
createCollapseAnimator(fabAction3, offset3));
animatorSet.start();
animateFab();
}
private void expandFab() {
fab.setImageResource(R.drawable.animated_plus);
AnimatorSet animatorSet = new AnimatorSet();
animatorSet.playTogether(createExpandAnimator(fabAction1, offset1),
createExpandAnimator(fabAction2, offset2),
createExpandAnimator(fabAction3, offset3));
animatorSet.start();
animateFab();
}
private Animator createCollapseAnimator(View view, float offset) {
return ObjectAnimator.ofFloat(view, TRANSLATION_Y, 0, offset)
.setDuration(getResources().getInteger(android.R.integer.config_mediumAnimTime));
}
private Animator createExpandAnimator(View view, float offset) {
return ObjectAnimator.ofFloat(view, TRANSLATION_Y, offset, 0)
.setDuration(getResources().getInteger(android.R.integer.config_mediumAnimTime));
}
private void animateFab() {
Drawable drawable = fab.getDrawable();
if (drawable instanceof Animatable) {
((Animatable) drawable).start();
}
}
public void fabAction1(View view) {
Log.d(TAG, "Action 1");
Toast.makeText(this, "Go shopping!", Toast.LENGTH_SHORT).show();
}
public void fabAction2(View view) {
Log.d(TAG, "Action 2");
Toast.makeText(this, "Gimme money!", Toast.LENGTH_SHORT).show();
}
public void fabAction3(View view) {
Log.d(TAG, "Action 3");
Toast.makeText(this, "Turn it up!", Toast.LENGTH_SHORT).show();
}
d)引用res/layout/activity_main.xml
删除fab声明:
<android.support.design.widget.FloatingActionButton
android:id="@+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:layout_margin="@dimen/fab_margin"
app:srcCompat="@android:drawable/ic_dialog_email" />
替换为:
<include layout="@layout/fab" />
最后的说明:
onClick
代码并替换为
onClickListener
。那些应该在评论中说出来
// insert onClickListener here
。只记得删除
onClick
文件中每个工厂的fab.xml
属性并删除
MainActivity
中的最后3个函数(fabAction1
,fabAction2
和fabAction3
)。我希望这可以帮助某人并抱歉留言。
答案 1 :(得分:1)
我想知道是否有办法使用默认的FloatingActionButton
轻松实现此目的
设计库中的FAB没有此功能。你需要寻找第三方FAB(在android-arsenal上有一些可供选择)
