I have a handler that is a TextWatcher
and i dont know how to get the View
that has changed text.
Here is my handler:
TextWatcher handler = new TextWatcher() {
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
// TODO Auto-generated method stub
}
@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
oldText = s.toString();
}
@Override
public void afterTextChanged(Editable s) {
//v.setText("afterTextChanged");
}
};
Note the commented part, that is what i want, to get the View
from the EditText
that has triggered the event, to change the text after the text was changed.
How i can reach this .setText()
method inside the afterTextChanged event? (Like onClick event that view is v
)
TextWatcher handler = new TextWatcher() { @Override public void onTextChanged(CharSequence s, int start, int before, int count) { // TODO Auto-generated method stub } @Override public void beforeTextChanged(CharSequence s, int start, int count, int after) { oldText = s.
Android EditText with TextWatcher (Searching data from ListView) Android EditText is a subclass of TextView. EditText is used for entering and modifying text. While using EditText width, we must specify its input type in inputType property of EditText which configures the keyboard according to input.
Android Dependency Injection using Dagger with Kotlin This example demonstrates how to use the TextWatcher class in kotlin. Step 1 − Create a new project in Android Studio, go to File ⇒New Project and fill all required details to create a new project. Step 2 − Add the following code to res/layout/activity_main. xml.
TextWatcher is a useful class provided by the Android Developer API. It can be used to watch a input text field and you can instantly update data on other views. It can be useful for counting the number of characters entered in the text field instantly and measuring password strength on entering etc.
public static class MyTextWatcher implements TextWatcher {
private EditText mEditText;
public MyTextWatcher(EditText editText) {
mEditText = editText;
}
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
oldText = mEditText.toString();
}
....
}
Add it with:
mFirstEditText.addTextChangedListener(new MyTextWatcher(mFirstEditText));
