Java – Is my code too repetitive?

I

was developing my word adventure game and wondered if there was an easier way to write duplicate code blocks, such as the one I had below.

In this block, the user is presented with N, E, S, W for North, East, South, and West. So I wrote each listener separately and included a try/catch block in each listener. But the whole block of code now does look like a duplicate.

Here is the code block:

btnNorth.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            tvIntro.setText("You go north");
            String testString = "nothing";
            try {
                testString = Encounter.EncounterGeneratorText();
            } catch (Exception e) {
                    e.printStackTrace();
                }
            testString = Encounter.EncounterGeneratorText();
            tvIntro.setText(testString);
            try {
                Thread.sleep(500);
            } catch (InterruptedException e) {
                 TODO Auto-generated catch block
                e.printStackTrace();
            }
            tvIntro.setText(testString);            
        }
    });

btnEast.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            tvIntro.setText("You go east");
            String testString = "nothing";
            try {
                testString = Encounter.EncounterGeneratorText();
            } catch (Exception e) {
                    e.printStackTrace();
                }
            testString = Encounter.EncounterGeneratorText();
            tvIntro.setText(testString);
            try {
                Thread.sleep(500);
            } catch (InterruptedException e) {
                 TODO Auto-generated catch block
                e.printStackTrace();
            }
            tvIntro.setText(testString);
        }
    });

btnSouth.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            tvIntro.setText("You go south");
            String testString = "nothing";
            try {
                testString = Encounter.EncounterGeneratorText();
            } catch (Exception e) {
                    e.printStackTrace();
                }
            testString = Encounter.EncounterGeneratorText();
            tvIntro.setText(testString);
            try {
                Thread.sleep(500);
            } catch (InterruptedException e) {
                 TODO Auto-generated catch block
                e.printStackTrace();
            }
            tvIntro.setText(testString);
        }
    });

btnWest.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            tvIntro.setText("you go west");
            String testString = "nothing";
            try {
                testString = Encounter.EncounterGeneratorText();
            } catch (Exception e) {
                    e.printStackTrace();
                }
            testString = Encounter.EncounterGeneratorText();
            tvIntro.setText(testString);
            try {
                Thread.sleep(500);
            } catch (InterruptedException e) {
                 TODO Auto-generated catch block
                e.printStackTrace();
            }
            tvIntro.setText(testString);
        };
    });

You can create an OnClickListener that all buttons will use, in which you will detect which button was clicked and perform direction-specific tasks in the switch statement.

Like this:

private OnClickListener DirectionClickListner = new OnClickListener() {
    public void onClick(View v) {
        switch (v.getId()) {
        case R.id.north:
            Set your strings for North
            break;
        case R.id.west:
            Set your strings for West
            break;
        case R.id.east:
            Set your strings for East
            break;
        case R.id.south:
            Set your strings for South
            break;
        }
    }
};
