Handling empty EditText with toast


You are getting an error, because your findViewById(...) isn't bound to the correct this. It should be outside of the onClick listener.

Typically, I would do something like the following:

public class MainActivity extends
Activity {

private EditText sun;
private EditText mon;
private EditText tue;
private EditText wed;
private EditText thu;
private EditText fri;
private EditText sat;
private EditText wage;

@Override
protected void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    instantiateViews();
}

private void instantiateViews() {

    sun  = (EditText) findViewById(R.id.sun1);
    mon  = (EditText) findViewById(R.id.mon1);
    tue  = (EditText) findViewById(R.id.tue1);
    wed  = (EditText) findViewById(R.id.wed1);
    thu  = (EditText) findViewById(R.id.thu1);
    fri  = (EditText) findViewById(R.id.fri1);
    sat  = (EditText) findViewById(R.id.sat1);
    wage = (EditText) findViewById(R.id.wage);
}

//Write whatever other code you would here
}

Also, I recommend you use TextUtils.isEmpty over your current method to check that wage is empty.

the EditText is empty and the method always returns true?
Change your if statement as follows: if (et_topic.getText().toString().trim().equals("")) EditText#getText() returns an Editable object, which won't be equal to "".

Notification like Toast but with longer duration
From a quick search in SO, you can find the Toast durations: private static final int LONG_DELAY = 3500; // 3.5 seconds private static final int SHORT_DELAY = 2000; // 2 seconds Now you can display multiple Toasts one after the other to look like it has a longer duration: final String msg = "Some text"; Runnable delayedToast = new Runnable() { @Override public void run() { Toas

Need Solution : Message is not Showing Toast
Don't mix multiple Writers and OutputStreams or Readers and InputStreams on the same socket. It won't work. PrintWriter is buffered. If you write something and then expect a response you need to flush it after the write.

How to show toast according to user input?
Your app crashes on the line final int Me= Integer.parseInt(a);, since your EditText will be empty in the OnCreatemethod and an empty string cannot be parsed to an integer. You should catch the NumberFormatException You should get the text in the OnClickListener, because only then you have given the user the opportunity to enter a value in the EditText. So your code will be: sub.setOnClickList
