Question

我试图使用[CDATA []]＆gt;正确的，因为我想在我的活动中包含URLS，但它没有显示在我的应用程序上，我不明白为什么。

谁能告诉我我做错了什么？我是否还需要在.java文件中添加内容？

表示输出的图片

string.xml

 <string name="about_body"><![CDATA[

public class MyAbout extends BaseActivity {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.my_about);

    FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);

        public void onClick(View view) {

        }
    });


    //Set nav drawer selected to second item in list
    mNavigationView.getMenu().getItem(4).setChecked(true);

}

((TextView) findViewById(R.id.about_body)).setText(Html.fromHtml(getString(R.string.about_body)));

Answer 1

将线性布局更改为相对布局内的

 public static class Reduce extends Reducer<Text,Text,NullWritable,Text>{

    public void reduce(NullWritable key, Iterable<Text> values, Context context) throws IOException, InterruptedException{

        try{                    
            for(Text val : values){

                context.write(key, new Text(val.toString()));
            }
        }catch(JSONException e){
            e.printStackTrace();
        }
    }
}

之后在活动 onCreate

中设置文字

<LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">

        <TextView
            android:id="@+id/title_about"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginBottom="8dp"
            android:layout_marginLeft="16dp"
            android:layout_marginRight="16dp"
            android:layout_marginTop="8dp"
            android:drawableLeft="@mipmap/ic_launcher"
            android:drawablePadding="8dp"
            android:gravity="center_vertical"
            android:textSize="24sp" />

        <ScrollView
            android:layout_width="match_parent"
            android:layout_height="0dp"
            android:layout_weight="1">

            <TextView
                android:id="@+id/about_body"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:padding="16dp"
                android:text="@string/about_body"
                android:textSize="14sp" />


        </ScrollView>

    </LinearLayout>

<强> EDITED

((TextView) findViewById(R.id.about_body)).setText(Html.fromHtml(getString(R.string.about_body)));

Answer 2

是的，你必须给文本属性提供String引用。使用+ id，您可以在R文件中创建新ID。

您可以直接获得该html文本代码，也可以看到以下链接，您可以从中获得想法

Android TextView supported Html Tags

第二件事就是你错过了一些关闭的标签，看看锚标签你没有把它放在那里

Answer 3

您正在使用字符串的ID，但您需要使用实际字符串，即@ string / about_body而不是@ + id / about_body。其余的看起来是正确的。

如何正确使用CDATA？
