java.util.logging.Handler
is the wrong class to import. You want to make sure you import android.os.Handler
Handler sendEmptyMessage() cannot resolve
Question
I have problem with handler. After create i want to send message to handler, but method sendEmptyMessage() cannot resolve. Handler must to update custom list adapter.
There is my code:
private Handler mHandler;
mHandler = new Handler() {
@Override
public void close() {}
@Override
public void flush() {}
@Override
public void publish(LogRecord record) {}
public void handleMessage(Message m)
{
catalogAdapter.notifyDataSetChanged();
}
};
mHandler.sendEmptyMessage(0);
Solution
OTHER TIPS
I don't see why you cannot resolve the sendEmptyMessage method. Maybe you have got a wrong import, check that.
On a side note, you just need to post a message to you handler as so :
new Handler(Looper.getMainLooper()).post(
new Runnable() {
@Override
public void run() {
catalogAdapter.notifyDataSetChanged();
}
});
Or even maybe create a background Thread.
As Massimo stated, your import should be :
import android.os.Handler;
mHandler.sendEmptyMessage(0);
is wrong, because there is no method:
public void handleMessage(int m);
Must be:
mHandler.sendEmptyMessage(null);
