Question

当我通过put extra发送字符串时，带下划线的字词不会加下划线

<string name="s_hello_txt">\n{ <u>hello all</u> }\n</string>

MainActivity按钮代码

public void c_hello(View v){
    Intent hello= new Intent(MainActivity.this,
            MainTextActivity.class);
    intent_collection_e3tiraf.putExtra("key",getResources().getString(R.string.s_hello_txt));
    startActivity(hello);
    finish();
}

MainActivityText onCreate Code

textview = (TextView) findViewById(R.id.id_text_txt);
    Intent n = getIntent();
    String mrng = n.getStringExtra("key");
    textview.setText(mrng);

如果我将带有直接字符串的文本放在下划线

例如，如果我放入MainActivityText（activity_maintext.xml）的布局

<TextView
    android:id="@+id/id_dailyprayers_txt"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="@string/s_hello_txt"
    android:textSize="30sp" />

MainActivityText中的textview显示文本（hello all）带下划线

任何帮助!!!!

Answer 1

只要字符串仍然具有下划线html，您就应该能够使用Html.fromHtml方法来设置字符串的样式。

textview.setText(Html.fromHtml(mrng));

Answer 2

实际上，字符串getResource().getString(R.string.s_hello_txt)没有加下划线。在strings.xml中添加html源代码的最佳方法是使用<![CDATA[html source code]]>。这是一个例子：

<string name="s_hello_txt"><![CDATA[<u>Text</u>]]></string>

然后使用Html.fromHtml(mrng)显示带下划线的字符串
