Question

try {
    answerField.setText("Unscrambling...This may take a minute");
    BufferedInputStream(getAssets().open("wordlist.txt"));
    BufferedInputStream[] textfile = new BufferedInputStream[28];
    for(int i = 0; i<28; i++){
        textfile[i] = new BufferedInputStream(getAssets().open(i+1+".txt"));
        }
    answerField.setText(Unscramble.go(tField.getText()+"", textfile));

My issue is with the line answerField.setText(“Unscrambling…This may take a minute”);

If the code is as-is, then this line will do nothing, but, if I take away the last line of the code answerField.setText(Unscramble.go(tField.getText()+””, textfile)); it works find and the TextView says “Unscrambling…this may take a minute”

The goal is for it to have that message until the program is done unscrambling, then it will have the results.

Any help would be really greatly appreciated, as I have no clue what I am doing or why this is happening.

Answer 1

The problem is that the UI does not update between the first call to setText and the second. One solution, as @AVD mentioned, is to use Toast.

The other solution, which I believe is recommended, is to use AsyncTask. The idea here would be to set your text to the “Unscrambling” message in onPreExecute, then run your main task in doInBackground, then finally set the text to the Unscramble.* string in onPostExecute.

The documentation link I provided above has a great AsyncTask code there, which can be manipulated to handle just about anything.
