Question

 <ViewFlipper
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:measureAllChildren="false">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="100dp"/>
    </RelativeLayout>

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="200dp">
    </RelativeLayout>

</ViewFlipper>

我有鳍状肢。并且动画可以改变视图效果：

Animation slideDown = AnimationUtils.loadAnimation(getActivity(), android.R.anim.slide_in_left);
slideDown.setDuration(900);
Animation slideUp = AnimationUtils.loadAnimation(getActivity(), android.R.anim.slide_out_right);
slideUp.setDuration(300);

mReceiverFlipper.setInAnimation(slideDown);
mReceiverFlipper.setOutAnimation(slideUp);

我的问题是我无法垂直动画 flipperView 。由于两个孩子的视图有不同的高度。当我在childViews fipperView animation之间翻转，在没有parseFloat($("#size").val());的情况下调整身高。

那么，当他的尺寸发生变化时，我怎样才能为flipperView设置动画？

Answer 1

您可以使用android:animateLayoutChanges属性。

在ViewFlipper上添加属性<ViewFlipper android:animateLayoutChanges="true" ...并将其设置为true。（((ViewFlipper) findViewById(/* your viewflipper id here*/)).getLayoutTransition().enableTransitionType(LayoutTransition.CHANGING)）

然后在代码中，您需要添加以下行以启用动画：

findViewById<ViewFlipper>(/* your viewflipper id here*/).layoutTransition.enableTransitionType(LayoutTransition.CHANGING)

或在科特林：

public static void TextToWord(string pWordDoc, string pMergeField, string pValue)
{
    Object oMissing = System.Reflection.Missing.Value;
    Object oTrue = true;
    Object oFalse = false;
    Word.Application oWord = new Word.Application();
    Word.Document oWordDoc = new Word.Document();
    oWord.Visible = true;

    Object oTemplatePath = pWordDoc;**//Here instead of doc file or doc file path I have a blobpath**
  //Something like this    
    //Object oTemplatePath = "https://bviewstorage.blob.core.windows.net/909347fb-e9ed-4f0c-9ef9- 
    //347ad017f7f9/localsiteuploads/92f9e761-65e2-46f9-82a1-a05fa9e26cda/file-sample_100kB-53c5fb9c-931d- 
    //4f95-b2cb-48b3a38e6f29.doc";
    oWordDoc = oWord.Documents.Add(ref oTemplatePath, ref oMissing, ref oMissing, ref oMissing);
    foreach (Word.Field myMergeField in oWordDoc.Fields)
    {
        Word.Range rngFieldCode = myMergeField.Code;
        String fieldText = rngFieldCode.Text;
        if (fieldText.StartsWith(" MERGEFIELD"))
        {
            Int32 endMerge = fieldText.IndexOf("\\");
            Int32 fieldNameLength = fieldText.Length - endMerge;
            String fieldName = fieldText.Substring(11, endMerge - 11);
            fieldName = fieldName.Trim();
            if (fieldName == pMergeField)
            {
                myMergeField.Select();
                oWord.Selection.TypeText(pValue);
            }
        }
    }
