If you use CodeView in an interesting project, I would like to know
Add CodeView to your project
Add CodeView from Maven Central
dependencies {
implementation 'io.github.amrdeveloper:codeview:1.2.1'
}
Or Add CodeView from Jitpack.IO
Add it to your root build.gradle
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}
Add the dependency
dependencies {
implementation 'com.github.AmrDeveloper:CodeView:1.2.1'
}
Documentation

Add CodeView on your xml
<com.amrdeveloper.codeview.CodeView
android:id="@+id/codeView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/darkGrey"
android:dropDownWidth="@dimen/dimen150dp"
android:dropDownHorizontalOffset="0dp"
android:dropDownSelector="@color/darkGrey"
android:gravity="top|start" />
Initialize CodeView
CodeView codeView = findViewById(R.id.codeview);
Clear all patterns from CodeView
codeView.resetSyntaxPatternList();
Add Patterns for your language, you can add any number of patterns
codeView.addSyntaxPattern(pattern, Color);
Or add all patterns as an Map Object
codeView.setSyntaxPatternsMap(syntaxPatterns);
Highlight the text depend on the new patterns
codeView.reHighlightSyntax();
Add error line with dynamic color to support error, hint, warn...etc
codeView.addErrorLine(lineNumber, color);
Clear all error lines
codeView.removeAllErrorLines();
Highlight the errors depend on the error lines
codeView.reHighlightErrors();
Add Custom AutoComplete Adapter
//Your language keywords
String[] languageKeywords = .....
//List item custom layout
int layoutId = .....
//TextView id on your custom layout to put suggestion on it
int viewId = .....
//Create ArrayAdapter object that contain all information
ArrayAdapter<String> adapter = new ArrayAdapter<>(context, layoutId, viewId, languageKeywords);
//Set the adapter on CodeView object
codeView.setAdapter(adapter);
Add Custom AutoComplete Adapter that support keywords and Snippets
List<Code> codes = new ArrayList<>();
codes.add(new Snippet(..., ..., ...));
codes.add(new Keyword(..., ..., ...));
//Your language keywords
String[] languageKeywords = .....
//List item custom layout
int layoutId = .....
//TextView id on your custom layout to put suggestion on it
int viewId = .....
CodeViewAdapter codeAdapter = new CodeViewAdapter(context, layoutId, viewId, codes);
codeView.setAdapter(codeAdapter);
Add Custom AutoComplete Tokenizer
codeView.setAutoCompleteTokenizer(tokenizer);
Set highlighter update delay
codeView.setUpdateDelayTime();
Enable/Disable highlight the code while the text is changing
codeView.setHighlightWhileTextChanging(enableHighlighter);
Enable/Disable line number
codeView.setEnableLineNumber(enableLineNumber);
Set line number text color
codeView.setLineNumberTextColor(Color.GREY);
Set line number text size
codeView.setLineNumberTextSize(size);
Set Tab length
codeView.setTabLength(4);
Enable/Disable Auto Indentation
codeView.setEnableAutoIndentation(enableIndentation);
Set Indentations Starts
codeView.setIndentationStarts(indentationStart);
Set Indentations Ends
codeView.setIndentationEnds(indentationEnds);
Change the matching highlighter color
codeView.setMatchingHighlightColor(color);
Get and save all the tokens that matching regex
List<Token> tokens = codeView.findMatches(regex);
Find and highlight the next matching token, returns null if not found
Token token = codeView.findNextMatch();
Find and highlight the previous matching token, returns null if not found
Token token = codeView.findPrevMatch();
Clear all matching highlighted token
