Modification on the accepted answer to clean out any existing capital letters and prevent the trailing space that the accepted answer leaves behind.

修改已接受的答案，以清除任何现有的大写字母，并防止已接受的答案留下的尾随空格。

public static String capitalize(@NonNull String input) {

    String[] words = input.toLowerCase().split(" ");
    StringBuilder builder = new StringBuilder();
    for (int i = 0; i < words.length; i++) {
        String word = words[i];

        if (i > 0 && word.length() > 0) {
            builder.append(" ");
        }

        String cap = word.substring(0, 1).toUpperCase() + word.substring(1);
        builder.append(cap);
    }
    return builder.toString();
}

you can use this method to do it programmatically

您可以使用此方法以编程方式执行此操作

public String wordFirstCap(String str)
{
    String[] words = str.trim().split(" ");
    StringBuilder ret = new StringBuilder();
    for(int i = 0; i < words.length; i++)
    {
        if(words[i].trim().length() > 0)
        {
            Log.e("words[i].trim",""+words[i].trim().charAt(0));
            ret.append(Character.toUpperCase(words[i].trim().charAt(0)));
            ret.append(words[i].trim().substring(1));
            if(i < words.length - 1) {
                ret.append(' ');
            }

Have a look at ACL WordUtils.

看看ACL worls。

WordUtils.capitalize("your string") == "Your String"

WordUtils。大写("your string") = "your string"

#8

android:inputType="textCapWords"

This will not work in TextView, which is valid for EditText only. so you have to do it manually.

这在TextView中不起作用，它只对EditText有效。所以你必须手动操作。

You can use capitalizeFully for make each word starts with capital.

你可以使用资本主义，让每个词都以资本开头。

#9

You can use

您可以使用

private String capitalize(final String line) {
   return Character.toUpperCase(line.charAt(0)) + line.substring(1);
}

Another approach is to use StringTokenizer class. The below method works for any number of words in a sentence or in the EditText view. I used this to capitalize the full names field in an app.

另一种方法是使用StringTokenizer类。下面的方法适用于句子或EditText视图中的任意数量的单词。我用它来大写应用程序中的全名字段。

public String capWordFirstLetter(String fullname)
{
    String fname = "";
    String s2;
    StringTokenizer tokenizer = new StringTokenizer(fullname);
    while (tokenizer.hasMoreTokens())
    {
        s2 = tokenizer.nextToken().toLowerCase();
        if (fname.length() == 0)
            fname += s2.substring(0, 1).toUpperCase() + s2.substring(1);
        else
            fname += " "+s2.substring(0, 1).toUpperCase() + s2.substring(1);
    }

    return fname;
}

You can try these attribute inside your XML tag given by:

您可以在XML标记中尝试以下属性:

To capitalize each word

利用每个单词

android:inputType="textCapWords"

To capitalize each word in start of each sentence:

在每个句子的开头用大写字母表示:

android:inputType="textCapSentences"

While this attribute is deprecated now:

虽然现在不赞成使用此属性:

android:capitalize    **// deprecated X**

#12

To capitalize each word in a sentence use the below attribute in xml of that paticular textView.

要将一个句子中的每个单词都大写，可以使用下面的属性，在这个patitextview的xml中。

android:inputType="textCapWords"

android:inputType = " textCapWords "
