I would like to programmatically set maxLength
property of TextView
as I don\'t want to hard code it in the layout. I can\'t see any set
best solution i found
textView.setText(text.substring(0,10));
For Kotlin and without resetting previous filters:
fun TextView.addFilter(filter: InputFilter) {
filters = if (filters.isNullOrEmpty()) {
arrayOf(filter)
} else {
filters.toMutableList()
.apply {
removeAll { it.javaClass == filter.javaClass }
add(filter)
}
.toTypedArray()
}
}
textView.addFilter(InputFilter.LengthFilter(10))
Easy way limit edit text character :
EditText ed=(EditText)findViewById(R.id.edittxt);
ed.setFilters(new InputFilter[]{new InputFilter.LengthFilter(15)});
Should be something like that. but never used it for textview, only edittext :
TextView tv = new TextView(this);
int maxLength = 10;
InputFilter[] fArray = new InputFilter[1];
fArray[0] = new InputFilter.LengthFilter(maxLength);
tv.setFilters(fArray);
I made a simple extension function for this one
/**
* maxLength extension function makes a filter that
* will constrain edits not to make the length of the text
* greater than the specified length.
*
* @param max
*/
fun EditText.maxLength(max: Int){
this.filters = arrayOf<InputFilter>(InputFilter.LengthFilter(max))
}
editText?.maxLength(10)
