如何根据String的大小自动调整TextView高度？

I want to know how to automatically adjust the size of the TextView according to the length of the String. I am getting some data from another Intent as a String and storing it in a TextView. If I leave it small, the whole text won't fit and only half of it is displayed. If I leave a big space for the TextView it does not look nice on the screen.

我想知道如何根据String的长度自动调整TextView的大小。我从另一个Intent获取一些数据作为String并将其存储在TextView中。如果我把它留小，整个文本将不适合，只显示一半。如果我为TextView留下一个很大的空间，它在屏幕上看起来不太好看。

The solution I found online was using extends TextView and using this method gives errors in my class and I have to change a lot of functions because of this

我在网上找到的解决方案是使用扩展TextView并使用此方法在我的课程中出错，我必须更改很多功能因为这个

2 个解决方案

#1

Use a multi-line TextView and set layout_height to wrap_content:

使用多行TextView并将layout_height设置为wrap_content：

<TextView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:singleLine="false"/>

Note: If you set layout_width to wrap_content it won't work properly. If you don't want the TextView to take up the entire width of the parent view then either:

注意：如果将layout_width设置为wrap_content，它将无法正常工作。如果您不希望TextView占用父视图的整个宽度，则：

Set it to a fixed width in XML, or
将其设置为XML中的固定宽度，或
Set the width programmatically, or
以编程方式设置宽度，或
Set layout_alignLeft/layout_alignRight etc in a RelativeLayout
在RelativeLayout中设置layout_alignLeft / layout_alignRight等
Set the layout_width to 0dp and use a layout_weight in a LinearLayout
将layout_width设置为0dp并在LinearLayout中使用layout_weight

If you are using xml file, just do this,

如果您使用的是xml文件，请执行此操作，

<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:singleLine="false"/>

And if you want to do dynamically do like this,

如果你想动态做这样的事，

TextView textView= new TextView(activity);
LinearLayout.LayoutParams param = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
textView.setLayoutParams(param);
