Set text in TextView using Html.fromHtml
提问by zaiff
I have to show a text in three parts, so i have used Html.fromHtml like this:
我必须分三部分显示文本，所以我使用了 Html.fromHtml 像这样：
txtvw.setText(Html.fromHtml("<p align=right> <b> "
+ "Hi!" + " </br> <font size=6>"
+ " How are you "+"</font> </br>"
+ "I am fine" + " </b> </p>"));
The HTML is correct but in device it's showing in one line.
HTML 是正确的，但在设备中它显示在一行中。
my xml declaration of textview is:
我的 textview xml 声明是：
<RelativeLayout
android:id="@+id/Home"
android:layout_width="fill_parent"
android:layout_height="60dp"
android:background="@drawable/transparentfooter"
android:layout_above="@+id/bottombar" >
<TextView
android:id="@+id/txt"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:textColor="@android:color/white"/>
</RelativeLayout>

The way you used the <br>tag is inappropriate. Use the following:
您使用<br>标签的方式不合适。使用以下内容：
txtvw.setText(Html.fromHtml("<p align=right> <b> "
+ "Hi!" + " <br/> <font size=6>"
+ " How are you "+"</font> <br/>"
+ "I am fine" + " </b> </p>"));

它应该是，<br/>而不是</br>我已经测试过这段代码，它按预期显示了 3 行。

Html.fromHtml(String source)
now Deprecated from Api-24.
现在已从 Api-24 弃用。
From Api-24 this method changed to
从 Api-24 开始，此方法更改为
Html.fromHtml(String source,int flags)
So we can use like below from Api 24
所以我们可以在 Api 24 中使用如下所示
txtvw.setText(Html.fromHtml("<p align=right> <b> "
+ "Hi!" + " <br/> <font size=6>"
+ " How are you "+"</font> <br/>"
+ "I am fine" + " </b> </p>"),Html.FROM_HTML_MODE_LEGACY);
