如何在文本视图中设置文本并将其格式化为代码?(Android Java)

Question

所以问题是这样的。我正在编写应用程序，我想在TextView中显示部分"java代码"，所以当我在TextView中将Text设置为一个简单的文本时。

是否可以显示所有标签颜色等类似"代码"的代码？

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 = "   @Overriden" +
"    public View onCreateView(LayoutInflater inflater, ViewGroup container,n" +
"                             Bundle savedInstanceState) {n" +
"        // Inflate the layout for this fragmentn" +
"        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) {
}
}

这是我尝试执行此操作时的片段代码：mCodeView.setOnHighlightListener(此)

setOnHightkightListener油漆为红色。

Answer 1

您可以使用此库来启用代码高亮显示。

Answer 2

您可以使用CodeView库并设置所需语言的配置，然后只需使用setText，它将用您想要的任何颜色高亮显示，您可以在运行时更改主题。

Answer 3

是的，可以使用html。您可以使用Html.fromHtml()来设置类似java代码和颜色的文本。
