# HashTagHelper
This is a library designed for highlighting hashtags ("#example") and catching click on them.
[](http://androidweekly.net/issues/issue-185)
[](https://android-arsenal.com/details/1/2953)
#Usage
Add this snippet to your project build.gradle file:
```
buildscript {
repositories {
jcenter()
}
}
```
Add this snippet to your module build.gradle file:
```
dependencies {
compile 'com.github.danylovolokh:hashtag-helper:1.1.0'
}
```
Getting click events and highligthing hashtags.
```
private HashTagHelper mTextHashTagHelper;
private TextView mHashTagText;
@Override
protected void onCreate(Bundle savedInstanceState) {
mHashTagText = (TextView) findViewById(R.id.text);
mTextHashTagHelper = HashTagHelper.Creator.create(getResources().getColor(R.color.colorPrimary), new HashTagHelper.OnHashTagClickListener() {
@Override
public void onHashTagClicked(String hashTag) {
}
});
// pass a TextView or any descendant of it (incliding EditText) here.
// Hash tags that are in the text will be hightlighed with a color passed to HasTagHelper
mTextHashTagHelper.handle(mHashTagText);
}
```
Highlighting without click events.
Just set "null" instead of HashTagHelper.OnHashTagClickListener;
```
mTextHashTagHelper = HashTagHelper.Creator.create(getResources().getColor(R.color.colorPrimary), null);
mTextHashTagHelper.handle(mHashTagText);
```
By default only digits and letters are valid symbols for hashtag
To add support of custom symbols like '_' or '-' you need to specify another parameter when creating HashTagHelper
```
char[] additionalSymbols = new char[]{
'_',
'$'
};
// If you set additional symbols not only letters and digits will be a valid symbols for hashtag
// Example: "hash_tag_with_underscore_and$dolar$sign$is$also$valid_hashtag"
mTextHashTagHelper = HashTagHelper.Creator.create(getResources().getColor(R.color.colorPrimary), null, additionalSymbols);
mTextHashTagHelper.handle(mHashTagText);
```
To get all hashtags from text.
```
// get all hashtags with "#", example: "#blueeyes"
List allHashTags = mTextHashTagHelper.getAllHashTags(true);
// get all hashtags without "#", example: "blueeyes"
List allHashTags = mTextHashTagHelper.getAllHashTags(false);
```
