Color Android textview between ** and ~

[wumpz]

Thx. Could you be more specific, give a better example. However if you simply refer to the tags and how you could add some more markdown stuff you have to adapt the oldTag, newTag method calls. However this only works, if the Android textview supports some kind of css, html or markdown styling. So this should be sufficient regarding to (https://www.myandroidsolutions.com/2017/09/29/android-html-textview/#.Y-K2K3bMJaY).

DiffRowGenerator generator = DiffRowGenerator.create()
                .showInlineDiffs(true)
                .inlineDiffByWord(true)
                .oldTag(f -> "~")      //introduce markdown style for strikethrough
                .newTag(f -> "**")     //introduce markdown style for bold
                .build();

The oldTag, newTag methods are used to provide a Function<Boolean, String>. This function is called with true before the changed text and with false after it. So this should do it:

DiffRowGenerator generator = DiffRowGenerator.create()
                .showInlineDiffs(true)
                .inlineDiffByWord(true)
                .oldTag(f -> f?"<font color='red'>":"</font>")      //introduce html style for strikethrough
                .newTag(f -> f?"<font color='green'>":"</font>")     //introduce html style for bold
                .build();

Thank you sir for your reply..I really very greatful to you.. And it's working...

But one thing, Actually I am trying to make an app that can compare 2 text files.. But in my code

DiffRowGenerator generator = DiffRowGenerator.create()
.showInlineDiffs(true)
.inlineDiffByWord(true)
.oldTag(f -> f?"<font color='red'>":"</font>")
.newTag(f -> f?"<font color='green'>":"</font>")
.build();
List<DiffRow> rows = generator.generateDiffRows(
Arrays.asList(FileUtil.readFile("/storage/emulated/0/Engine.java")),
Arrays.asList(FileUtil.readFile("/storage/emulated/0/Engine (1).java")));
for (DiffRow row : rows) {
  textview1.setText(Html.fromHtml(row.getNewLine(), >Html.FROM_HTML_MODE_COMPACT));
  textview2.setText(Html.fromHtml(row.getOldLine(), >Html.FROM_HTML_MODE_COMPACT));
}

Here I defined all the requirements but I am confused, after text comparator why textview showing only the text line where the text is deleted or modified ... Just see my image , this portion is modified and it only showing in the textview. not my other text ....How to solve it ..Thanks ❤️

[wumpz]

generator.reportLinesUnchanged(true) delivers unchanged lines as well.

@wumpz

Sir giving same result..only one line even the if file have 3 line and 2nd and 3rd line have some text changes..but after text compare only showing the last line modification comparison not the 2nd line

[wumpz]

You overwrite the previous line within your for loop. setText replaces text and does not append. So no problem with the diff tool.

@wumpz sir explain more clearly sir I unable to understand...Sir I am new

progressDialog = new ProgressDialog(MainActivity.this);
progressDialog.setMessage("Processing...");
progressDialog.show();
final Handler mHandler = new Handler() {
public void handleMessage(Message msg) {
progressDialog.dismiss();
}
};
new Thread() {
public void run() {
Looper.prepare();
try {
DiffRowGenerator generator = DiffRowGenerator.create()
.showInlineDiffs(true)
.inlineDiffByWord(true)
.replaceOriginalLinefeedInChangesWithSpaces(false)
.reportLinesUnchanged(true)
.ignoreWhiteSpaces(false)
.oldTag(f -> f?"":"")
.newTag(f -> f?"":"")
.build();
List rows = generator.generateDiffRows(
Arrays.asList(textview1.getText().toString()),
Arrays.asList(textview2.getText().toString()));
for (DiffRow row : rows) {
textview1.setText(textview1.getText().toString() + Html.fromHtml(row.getNewLine(), Html.FROM_HTML_MODE_COMPACT));
textview2.setText(textview2.getText().toString() + Html.fromHtml(row.getOldLine(), Html.FROM_HTML_MODE_COMPACT));
}
} catch (Exception e) {
SketchwareUtil.showMessage(getApplicationContext(), e.toString());
}
mHandler.sendEmptyMessage(0);
Looper.loop();
} }.start();

I have set a loop here but not working...

There is 3 errors but it don't mentioning in comparison

Explain me with this code sir ....for which I can use it in my project thank you ♥️

[wumpz]

At first glance, you do not use your original DiffRowGenerator anymore. Why? It worked. Now you do not include any formatting tags into your found diffs

.oldTag(f -> f?"":"")
.newTag(f -> f?"":"")

What does this do? Nothing. So nothing is hilited in your text.
