您好,我尝试制作动画有问题.

我使用这个库AndroidViewAnimations.

这是我的布局xml代码:

    <Button
         android:id="@+id/buttonDetails"
         style="@style/Button_Details"/>

    <LinearLayout
        android:id="@+id/linearLayoutDetails"
        android:visibility="gone"
        style="@style/LinearLayout_Details">

        <CheckBox
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="@string/checkbox_clmn_text"
            android:checked="true"/>
        <CheckBox
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="@string/checkbox_clme_text"
            android:checked="true"/>
        <CheckBox
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="@string/checkbox_clmn_text"
            android:checked="true"/>
        <CheckBox
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="@string/checkbox_clmn_text"
            android:checked="true"/>
        <CheckBox
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="@string/checkbox_clmn_text"
            android:checked="true"/>
        <CheckBox
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="@string/checkbox_clmn_text"
            android:checked="true"/>

    </LinearLayout>

在这里我的java代码:

// Declare Variables
@ViewById
LinearLayout linearLayoutDetails;

@Click
void buttonDetails() {
    // Checks Linear Layout Visibility
    if (linearLayoutDetails.getVisibility() == View.GONE) {
        // Sets linearLayoutDetails Visibility to VISIBLE
        linearLayoutDetails.setVisibility(View.VISIBLE);
        // Makes Appear Animation
        YoYo.with(Techniques.SlideInDown)
                .duration(700)
                .playOn(linearLayoutDetails);
    } else …
