Question

我正在使用 SpannableStringBuilder 在 TextView 中显示图像。但是，如果图像将停留在 TextView 中的行尾，它就会消失。如果我增加文本的大小，它将再次可见。我该如何解决？

这是我在 TextView 中添加图像的代码：

SpannableStringBuilder ssb = new SpannableStringBuilder();
ssb.setSpan(new ImageSpan(createClusterBitmap(idOfAyat)), ssb.length() - 1, ssb.length(), 0);
itemViewHolder.kuranArabic.setText(ssb);

商品的 XML 代码：

        <TextView
            android:id="@+id/kuranArabic"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_centerHorizontal="true"
            android:layout_margin="@dimen/_4sdp"
            android:fontFamily="@font/scheherazade"
            android:gravity="center_horizontal"
            android:textAlignment="center"
            android:textColor="?attr/color2"
            android:textSize="@dimen/_27sdp" />

我附上了两张图片。第一个是当停留在文本视图末尾时消失的图像。第二个出现在第一个位置时可见。

First Picture if StackOverflow's link doesn't work

Second Picture if StackOverflow's link doesn't work

附言我将不胜感激任何帮助。这是我的第一个问题，不要那么强烈地评判我。 :)

我通过向 Spannable String Builder 添加一个名为 Spannable.SPAN_EXCLUSIVE_EXCLUSIVE 的标志解决了我的问题。
