Sie auf diese CodeView library beziehen könnte, die CodeView ‚s-Typ ist ein WebView aber es könnte die gleiche Funktion implementieren. Und man konnte mit ihm direkt per Download von nuget Paket:
die Ansicht auf Ihrem Layout hinzufügen:
<br.tiagohm.codeview.CodeView
android:id="@+id/codeView"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
app:cv_font_size="14"
app:cv_highlight_line_number="36"
app:cv_show_line_number="true"
app:cv_start_line_number="0"
app:cv_wrap_line="true"
app:cv_zoom_enable="true">
</br.tiagohm.codeview.CodeView>
Wenn es verwenden:
public class CodeViewActivity : AppCompatActivity, CodeView.IOnHighlightListener
{
CodeView mCodeView;
private ProgressDialog mProgressDialog;
private int themePos = 0;
protected override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
SetContentView(Resource.Layout.codeView);
mCodeView = FindViewById<CodeView>(Resource.Id.codeView);
mCodeView.SetOnHighlightListener(this)
.SetOnHighlightListener(this)
.SetTheme(Br.Tiagohm.Theme.ArduinoLight)
.SetCode(JAVA_CODE)
.SetLanguage(Language.Auto)
.SetWrapLine(true)
.SetFontSize(14)
.SetZoomEnabled(true)
.SetShowLineNumber(true)
.SetStartLineNumber(1)
.Apply();
mCodeView.SetTheme(Br.Tiagohm.Theme.All.ElementAt(1)).Apply();
}
private void setHighlightTheme(int pos)
{
mCodeView.SetTheme(Br.Tiagohm.Theme.All.ElementAt(pos)).Apply();
Toast.MakeText(this, Br.Tiagohm.Theme.All.ElementAt(pos).Name, ToastLength.Short).Show();
}
public void OnFinishCodeHighlight()
{
if (mProgressDialog != null)
{
mProgressDialog.Dismiss();
}
Toast.MakeText(this, "line count: " + mCodeView.LineCount, ToastLength.Short).Show();
}
public void OnFontSizeChanged(int sizeInPx)
{
Log.Debug("TAG", "font-size: " + sizeInPx + "px");
}
public void OnLanguageDetected(Language language, int relevance)
{
Toast.MakeText(this, "language: " + language + " relevance: " + relevance, ToastLength.Short).Show();
}
public void OnLineClicked(int lineNumber, string content)
{
Toast.MakeText(this, "line: " + lineNumber + " html: " + content, ToastLength.Short).Show();
}
public void OnStartCodeHighlight()
{
mProgressDialog = ProgressDialog.Show(this, null, "Carregando...", true);
