Android XML：當TextView包含另一個TextView時使用ellipsize嗎？

Question

如設計中所示，我需要一個TextView，當它遇到另一個TextView時它會變橢圓（現在暫時忘記小箭頭圖像）。 擴展按鈕在底部，而容器的最大高度是固定的。

我正在發布暫時無法使用的代碼，因為TextViews重疊了。 請提出更改建議。

 <?xml version="1.0" encoding="utf-8"?> <RelativeLayout 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:id="@+id/expandable" tools:context="akshay.expandableview.MainActivity" android:layout_width="208dp" android:layout_height="wrap_content" android:maxHeight="204dp" android:background="#abcdef" android:padding="8dp"> <TextView android:id="@+id/content" android:layout_width="wrap_content" android:layout_height="wrap_content" android:textSize="16dp" android:lineSpacingMultiplier="1.2" android:textColor="#000" android:ellipsize="end" android:maxLines="8" android:text="It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like)."/> <TextView android:id="@+id/expand_btn" android:layout_width="70dp" android:layout_height="20dp" android:background="#fedcba" android:layout_alignBottom="@+id/content" android:layout_alignParentRight="true" android:text="Expand" android:gravity="center"/> </RelativeLayout>

您可以檢查TextView是否為橢圓形：

boolean isElipsized = false;
Layout layout = textview1.getLayout();
if(layout != null) {
    int lines = layout.getLineCount();
    if(lines > 0) {
        int ellipsisCount = layout.getEllipsisCount(lines-1);
        if (ellipsisCount > 0) {
            isElipsized = true;
        } 
    } 
}

if(isElipsized) {
    //show the "show more" view
}

要將一個TextView環繞另一個，可以使用以下問題
