                public Line() {
                }

                public Line(ArrayList<String> words, float spacing) {
                        this.words = words;
                        this.spacing = spacing;
                }

                public void setSpacing(float spacing) {
                        this.spacing = spacing;
                }

                public float getSpacing() {

                public void addWord(String s) {

                public ArrayList<String> getWords() {
                        return words;
                }
        }
}

将上面的类添加到你的src文件夹中，并使用这个示例代码添加到你的布局中:

JustifiedTextView jtv= new JustifiedTextView(getApplicationContext(), "Lorem ipsum dolor sit amet... ");
LinearLayout place = (LinearLayout) findViewById(R.id.book_profile_content);
place.addView(jtv);

为了在android中证明文本，我使用了WebView

    setContentView(R.layout.main);

    WebView view = new WebView(this);
    view.setVerticalScrollBarEnabled(false);

    ((LinearLayout)findViewById(R.id.inset_web_view)).addView(view);

    view.loadData(getString(R.string.hello), "text/html; charset=utf-8", "utf-8");

和html。

<string name="hello">
<![CDATA[
<html>
 <head></head>
 <body style="text-align:justify;color:gray;background-color:black;">
  Lorem ipsum dolor sit amet, consectetur 
  adipiscing elit. Nunc pellentesque, urna
  nec hendrerit pellentesque, risus massa
 </body>
</html>
]]>
</string>

我还不能上传图片来证明它，但“它对我有用”。

@CommonsWare的答案是正确的。Android 8.0+确实支持“完全论证”(或简单的“论证”，因为它有时被含糊地提到)。

Android还支持“左/右文本对齐”。请参阅维基百科关于区分理由的文章。许多人认为“对齐”的概念包括完全对齐以及左/右文本对齐，这是他们在想要进行左/右文本对齐时最终搜索的内容。这个答案解释了如何实现左/右文本对齐。

可以实现左/右文本对齐(而不是问题所询问的完全对齐)。为了演示，我将使用一个基本的2列表单(标签在左列，文本字段在右列)作为示例。在本例中，左列标签中的文本将右对齐，因此它们将与右列中的文本字段齐平。

在XML布局中，你可以得到的TextView元素本身(左列)对齐到右边，通过添加以下属性在所有的TextView:

<TextView
   ...
   android:layout_gravity="center_vertical|end">
   ...
</TextView>

但是，如果文本换行到多行，文本仍将在TextView内保持左对齐。添加以下属性使实际文本在TextView内右对齐(不规则左对齐):

<TextView
   ...
   android:gravity="end">
   ...
</TextView>

重力属性指定如何对齐TextView内的文本layout_gravity指定如何对齐/布局TextView元素本身。

Simplay我们可以使用android: justify mode ="inter_word"

 <TextView
 android:justificationMode="inter_word"
 android:id="@+id/messageTv"
 android:layout_width="match_parent"
 android:layout_height="wrap_content"
 android:layout_margin="@dimen/text_margin"
 android:paddingTop="15sp"
 android:textAppearance="@style/TextAppearance.Material3.TitleMedium" />

XML布局:声明WebView而不是TextView

<WebView
 android:id="@+id/textContent"
 android:layout_width="fill_parent"
 android:layout_height="wrap_content" />

Java代码:设置文本数据到WebView

WebView view = (WebView) findViewById(R.id.textContent);
String text;
text = "<html><body><p align=\"justify\">";
text+= "This is the text will be justified when displayed!!!";
text+= "</p></body></html>";
view.loadData(text, "text/html", "utf-8");

这也许能解决你的问题。 它完全为我工作。

Android目前还不支持完全的理由。我们可以使用Webview和证明HTML而不是使用textview。它工作得很好。如果你们不清楚，可以问我:)
