Question

Hi im trying to set the value of a textview with .setText in a method that is run by a thread but it is being appended to the TextView instead. The parameter String f is a being send to the method in a for loop like this:

    for (int j = 0; j < 5; j++) {
        String[] string = array[j].split(":");
        String y= string[0];
        String x= string[1];
        determineSeat(y, something, x);
    }
}

private void determineSeat(String is, String cs, String f)
{
            TextView txtHand = null;
    String txt = null;

    if (iSeat < cSeat) {
        x = cSeat - iSeat;

        if (x == 1) {
            txtHand = (TextView) findViewById(R.id.txtHand8);
            txt = txtHand.getText().toString();
            txtHand.setText("");
            txtHand.setText(txt + ":"  + f);
        }
}

XML:

<TextView
    android:id="@+id/txtHand1"
    android:layout_width="73dp"
    android:layout_height="wrap_content"
    android:layout_above="@+id/textView1"
    android:layout_centerHorizontal="true"
    android:text=" " />

I want it to be cleared everytime i put something in the textview instead of being appended anyone knows what the problem is?

You are setting it to "txt + ":" + f". "txt" is defined as whatever was already in the textview. If you just want to have it set to "f" every time the method is called, do "txtHand.setText(f);" As is, you are asking it to take whatever is currently in the textview, and add a colon and "f."
