设置TextView样式(粗体或斜体)

Question

如何TextView在Java中设置样式(粗体斜体)而不使用XML布局？

换句话说,我需要android:textStyle用Java 编写.

Answer 1

textView.setTypeface(null, Typeface.BOLD_ITALIC);
textView.setTypeface(null, Typeface.BOLD);
textView.setTypeface(null, Typeface.ITALIC);
textView.setTypeface(null, Typeface.NORMAL);

保留以前的字体

textView.setTypeface(textView.getTypeface(), Typeface.BOLD_ITALIC)

Answer 2

尝试将此设置TextView为粗体或斜体

textView.setTypeface(textView.getTypeface(), Typeface.BOLD);
textView.setTypeface(textView.getTypeface(), Typeface.ITALIC);
textView.setTypeface(textView.getTypeface(), Typeface.BOLD_ITALIC);

Answer 3

编程方式:

您可以使用setTypeface()以下方式编程:

textView.setTypeface(null, Typeface.NORMAL);      // for Normal Text
textView.setTypeface(null, Typeface.BOLD);        // for Bold only
textView.setTypeface(null, Typeface.ITALIC);      // for Italic
textView.setTypeface(null, Typeface.BOLD_ITALIC); // for Bold and Italic

XML:

您可以直接在XML文件中设置<TextView />:

android:textStyle="normal"
android:textStyle="normal|bold"
android:textStyle="normal|italic"
android:textStyle="bold"
android:textStyle="bold|italic"

Answer 4

您有两种选择:

选项1(仅适用于粗体,斜体和下划线):

String s = "<b>Bolded text</b>, <i>italic text</i>, even <u>underlined</u>!"
TextView tv = (TextView)findViewById(R.id.THE_TEXTVIEW_ID);
tv.setText(Html.fromHtml(s));

选项2:

使用Spannable ; 它更复杂,但您可以动态修改文本属性(不仅是粗体/斜体,还有颜色).

Answer 5

编程方式:

您可以使用setTypeface()方法以编程方式执行:

下面是默认字体的代码

textView.setTypeface(null, Typeface.NORMAL);      // for Normal Text
textView.setTypeface(null, Typeface.BOLD);        // for Bold only
textView.setTypeface(null, Typeface.ITALIC);      // for Italic
textView.setTypeface(null, Typeface.BOLD_ITALIC); // for Bold and Italic

如果要设置自定义字体:

textView.setTypeface(textView.getTypeface(), Typeface.NORMAL);      // for Normal Text
textView.setTypeface(textView.getTypeface(), Typeface.BOLD);        // for Bold only
textView.setTypeface(textView.getTypeface(), Typeface.ITALIC);      // for Italic
textView.setTypeface(textView.getTypeface(), Typeface.BOLD_ITALIC); // for Bold and Italic

XML:

您可以直接在XML文件中设置<TextView />如下:

android:textStyle="normal"
android:textStyle="normal|bold"
android:textStyle="normal|italic"
android:textStyle="bold"
android:textStyle="bold|italic"

或者您可以设置您的fav字体(来自资产).有关更多信息,请参阅链接

Answer 6

您可以使用下面给出的示例设置不同的字体 -

textView.setTypeface(textView.getTypeface(), Typeface.BOLD);
textView.setTypeface(textView.getTypeface(), Typeface.ITALIC);
textView.setTypeface(textView.getTypeface(), Typeface.BOLD_ITALIC);

或者如果您想设置不同的字体及其字样。将其添加到 asset 或 raw 文件夹中，然后像这样使用它

  Typeface face= Typeface.createFromAsset(getAssets(), "font/font.ttf");
  tv1.setTypeface(face);

  Typeface face1= Typeface.createFromAsset(getAssets(), "font/font1.ttf");
  tv2.setTypeface(face1);

Answer 7

TextView text = (TextView)findViewById(R.id.THE_TEXTVIEW_ID);

现在设置textview属性..

text.setTypeface(null, Typeface.BOLD);  //-- for only bold the text
text.setTypeface(null, Typeface.BOLD_ITALIC);  //-- for  bold & italic the text
text.setTypeface(null, Typeface.ITALIC);  // -- for  italic the text

Answer 8

尝试TextView 通过java代码设置你的风格

txt1.setTypeface(null,Typeface.BOLD_ITALIC);

Answer 9

只是如果你想使文字变粗.在文本视图属性的布局中写下此行

android:textStyle="bold"

Answer 10

TextView text = (TextView)findViewById(R.layout.textName);
text.setTypeface(null,Typeface.BOLD);

Answer 11

这将是

yourTextView.setTypeface(null,Typeface.DEFAULT_BOLD);

斜体应该可以替换Typeface.DEFAULT_BOLD为Typeface.DEFAULT_ITALC.

让我知道它是如何工作的.

Answer 12

textView.setTypeface(null, Typeface.BOLD_ITALIC);
textView.setTypeface(null, Typeface.BOLD);
textView.setTypeface(null, Typeface.ITALIC);
textView.setTypeface(null, Typeface.NORMAL);

保留之前的字体

textView.setTypeface(textView.getTypeface(), Typeface.BOLD_ITALIC)

Answer 13

尝试这个：

textView.setTypeface(textView.getTypeface(), Typeface.BOLD);
textView.setTypeface(textView.getTypeface(), Typeface.ITALIC);
textView.setTypeface(textView.getTypeface(), Typeface.BOLD_ITALIC);

Answer 14

使用textView.setTypeface(Typeface tf, int style);设置的样式属性TextView.有关详细信息,请参阅开发人员文档

Answer 15

试试这个:
