android EditText - finished typing event

Question

I want to catch an event when the user finishes editing EditText.

How can it be done?

Answer 1

I had the same problem when trying to implement 'now typing' on chat app. try to extend EditText as follows:

public class TypingEditText extends EditText implements TextWatcher {

private static final int TypingInterval = 2000;


public interface OnTypingChanged {
    public void onTyping(EditText view, boolean isTyping);
}
private OnTypingChanged t;
private Handler handler;
{
    handler = new Handler();
}
public TypingEditText(Context context, AttributeSet attrs, int defStyleAttr) {
    super(context, attrs, defStyleAttr);
    this.addTextChangedListener(this);
}

public TypingEditText(Context context, AttributeSet attrs) {
    super(context, attrs);
    this.addTextChangedListener(this);
}

public TypingEditText(Context context) {
    super(context);
    this.addTextChangedListener(this);
}

public void setOnTypingChanged(OnTypingChanged t) {
    this.t = t;
}

@Override
public void afterTextChanged(Editable s) {
    if(t != null){
        t.onTyping(this, true);
        handler.removeCallbacks(notifier);
        handler.postDelayed(notifier, TypingInterval);
    }

}

private Runnable notifier = new Runnable() {

    @Override
    public void run() {
        if(t != null)
            t.onTyping(TypingEditText.this, false);
    }
};

@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) { }


@Override
public void onTextChanged(CharSequence text, int start, int lengthBefore, int lengthAfter) { }

}
