在TextView上设置Ellipsize可以减少一行显示的行(而不是仅限于最后一行)

Question

当我使用TextView与singleLine="true"和ellipsize="end"(我的前的TextView), 效果很好

但在另一个 TextView有超过1行(在我的情况下,在我的底部3行TextView), lines="3" and maxLines="3" and ellipsize="end", 不能正常工作.

当我没有放入ellipsize="end"tvDesc时,它显示3行,这没关系.这是代码:XML:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <ImageView
        android:id="@+id/imgv"
        android:layout_width="65dp"
        android:layout_height="80dp"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:src="@drawable/img1"
        android:scaleType="fitXY" />

    <TextView
        android:id="@+id/tvTitle"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_toRightOf="@+id/imgv"
        android:background="@android:color/white"
        android:textColor="@android:color/black"
        android:text="Title testing line number and ellipsize at end"
        android:maxLines="1"
        android:singleLine="true"
        android:ellipsize="end"    <---  WORKS WELL
        android:textAppearance="?android:attr/textAppearanceMedium" />

    <TextView
        android:id="@+id/tvDesc"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/tvTitle"
        android:layout_toRightOf="@+id/imgv"
        android:layout_alignBottom="@+id/imgv"
        android:layout_alignParentRight="true"
        android:textSize="14dp"
        android:lines="3"
        android:maxLines="3"
                       <----------  WITHOUT ellipsize

        android:text="I wanna this textview of having 3 lines and ellipsize at END and at this time I am Testing for it. This TextView shows 3 lines WITHOUT ellipsize property, but shows only 2 Lines when ELLIPSIZE property is setted"
        android:textAppearance="?android:attr/textAppearanceMedium" />

</RelativeLayout>

上面的代码显示了带有3行和No-Ellipsize的TextView tvDesc.这是图片:

但是,我想椭圆化,所以我使用以下代码:XML:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <ImageView
        android:id="@+id/imgv"
        android:layout_width="65dp"
        android:layout_height="80dp"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:src="@drawable/img1"
        android:scaleType="fitXY" />

    <TextView
        android:id="@+id/tvTitle"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_toRightOf="@+id/imgv"
        android:background="@android:color/white"
        android:textColor="@android:color/black"
        android:text="Title testing line number and ellipsize at end"
        android:maxLines="1"
        android:singleLine="true"
        android:ellipsize="end"
        android:textAppearance="?android:attr/textAppearanceMedium" />

    <TextView
        android:id="@+id/tvDesc"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/tvTitle"
        android:layout_toRightOf="@+id/imgv"
        android:layout_alignBottom="@+id/imgv"
        android:layout_alignParentRight="true"
        android:textSize="14dp"
        android:lines="3"
        android:maxLines="3"
        android:ellipsize="end"    <------  WITH  ELLIPSIZE

        android:text="I wanna this textview of having 3 lines and ellipsize at END and at this time I am Testing for it. This TextView shows 3 lines WITHOUT ellipsize property, but shows only 2 Lines when ELLIPSIZE property is setted"
        android:textAppearance="?android:attr/textAppearanceMedium" />

</RelativeLayout>

其中只显示了2行和Ellipsize的TextView tvDesc,

这不是正确的dezired UI,如下所示:

我想在带有ellipsize的TextView tvDesc中使用3行

谁能帮我.？

Answer 1

这是迄今为止我发现并且目前正在部署中使用的最简单的解决方案.如果您需要任何其他帮助,请告诉我们!

哦,记得删除android:ellipsizeXML 中的标记,因为您将使用底部代码在3行结束时自动进行椭圆化处理.

TextView snippet;
snippet.setText("loren ipsum dolor loren ipsum dolor loren ipsum dolor loren ipsum dolor loren ipsum dolor loren ipsum dolor loren ipsum dolor loren ipsum dolor loren ipsum dolor loren ipsum dolor loren ipsum dolor loren ipsum dolor loren ipsum dolor loren ipsum dolor ")
ViewTreeObserver vto = this.snippet.getViewTreeObserver();
vto.addOnGlobalLayoutListener(new OnGlobalLayoutListener() {

    @Override
    public void onGlobalLayout() {
        ViewTreeObserver obs = snippet.getViewTreeObserver();
        obs.removeGlobalOnLayoutListener(this);
        if (snippet.getLineCount() > 3) {
            int lineEndIndex = snippet.getLayout().getLineEnd(2);
            String text = snippet.getText().subSequence(0, lineEndIndex - 3) + "...";
            snippet.setText(text);
        }
    }
});

只是设置android:maxLines和android:ellipsize.

<TextView
        android:id="@+id/tv_dua"
        android:ellipsize="end"
        android:maxLines="3"
        android:text="long text"
        android:textAppearance="?android:attr/textAppearanceMedium" />
