java - 如何在textview中设置文本并将其格式化为代码？ (Android Java)

Question

所以问题是这样。我正在编写应用程序，并且想在TextView中显示“ java代码”的一部分，因此当我在TextView中设置Text时，它看起来像一个简单的文本。

是否可以显示带有所有标签颜色的代码之类的“代码”等？

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

import br.tiagohm.codeview.Language;
import br.tiagohm.codeview.Theme;
import io.github.kbiakov.codeview.CodeView;


/**
 * A simple {@link Fragment} subclass.
 */
public class FragmentActivityTop extends Fragment implements br.tiagohm.codeview.CodeView.OnHighlightListener {
    CodeView mCodeView;
int tag=0;
    public FragmentActivityTop() {
        // Required empty public constructor
    }


    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        //CodeProcessor.init(getContext());
        View v =inflater.inflate(R.layout.activity_fragment_top, container, false);

        //CodeView codeView = (CodeView) v.findViewById(R.id.code_viewjava);

        String code = "   @Override\n" +
                "    public View onCreateView(LayoutInflater inflater, ViewGroup container,\n" +
                "                             Bundle savedInstanceState) {\n" +
                "        // Inflate the layout for this fragment\n" +
                "        View v = inflater.inflate(R.layout.fragment_xml, container, false);\n" +
                "\n" +
                "        WebView webView = (WebView)v.findViewById(R.id.webfragxml);";


        mCodeView = (CodeView)v.findViewById(R.id.codeView);

        mCodeView.setOnHighlightListener(this)
                .setOnHighlightListener(this)
                .setTheme(Theme.AGATE)
                .setCode(code)
                .setLanguage(Language.JAVA)
                .setWrapLine(true)
                .setFontSize(14)
                .setZoomEnabled(true)
                .setShowLineNumber(true)
                .setStartLineNumber(9000)
                .apply();

        return v;
    }


    @Override
    public void onStartCodeHighlight() {

    }

    @Override
    public void onFinishCodeHighlight() {

    }

    @Override
    public void onLanguageDetected(Language language, int i) {

    }

    @Override
    public void onFontSizeChanged(int i) {

    }

    @Override
    public void onLineClicked(int i, String s) {

    }
}

这是我尝试执行的片段代码：
mCodeView.setOnHighlightListener（this）

setOnHightkightListener绘制为红色。

Answer 1

您可以使用this library启用代码突出显示。
