Can I find out why my listview custom adapter looks like this?
Picture
Codes:
MainActivity.java
public class MainActivity extends AppCompatActivity { CurrencyRatesDetails crd = new CurrencyRatesDetails(); TextView inputCurrTV, convertedAmtTV; ListView currencyLV; EditText inputAmtET; ArrayAdapter<String> adapter; String[] currNameArr = crd.getNames(); String[] currCodeArr = crd.getCodes(); String[] currRateArr = crd.getRates(); Context context; int index = 0; //String[] rateCurrArr = {"AUD", "BGN", "BRL", "CAD", "CHF", "CNY"}; //double[] rateArr = {0.944, 1.2824, 2.2842, 0.96158, 0.70946, 4.8624} Menu myMenu = null; double rate, amtInput, finalConversion; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); context = this; inputAmtET = (EditText) findViewById(R.id.inputAmtET); convertedAmtTV = (TextView) findViewById(R.id.convertedAmtTV); inputCurrTV = (TextView) findViewById(R.id.inputCurrTV); currencyLV = (ListView) findViewById(R.id.currencyLV); //Resources myRes = this.getResources(); //currArr = myRes.getStringArray(R.array.currencyList); //adapter = ArrayAdapter.createFromResource(this, R.array.currencyList, android.R.layout.simple_selectable_list_item); //adapter = new ArrayAdapter<String>(this, android.R.layout.simple_selectable_list_item, currNameArr); //currencyLV.setAdapter(adapter); currencyLV.setAdapter(new CustomAdapterLV(this, currNameArr, currCodeArr, currRateArr)); currencyLV.setOnItemClickListener(new AdapterView.OnItemClickListener() { @Override public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) { inputCurrTV.setText(currCodeArr[i]); index = i; //Getting rate based on selected currency code //rate = rateArr[i]; } }); } public boolean onCreateOptionsMenu(Menu menu) { super.onCreateOptionsMenu(menu); this.myMenu = menu; addMenuItems(menu); getMenuInflater().inflate(R.menu.mainmenu, menu); return true; } private void addMenuItems(Menu menu) { int index = 200; menu.add(index, index, index, "Settings"); menu.add(index, index + 1, index + 1, "Add Custom Rate"); menu.add(index, index + 2, index + 2, "Load Default Rates"); } public boolean onOptionsItemSelected(MenuItem item) { //getOrder() to get Menu Item at this specific orderId if (item.getOrder() == 123) { amtInput = Double.parseDouble(inputAmtET.getText().toString()); //finalConversion = amtInput / rate; finalConversion = crd.conversion(amtInput, index); //Formatting converted value to 2d.p String finalValue = String.format("%.2f", finalConversion); convertedAmtTV.setText(finalValue); } else if (item.getItemId() == 201) { Intent myIntent = new Intent(MainActivity.this, CustomXchangeRate.class); startActivity(myIntent); } return true; }

Custom LV adapter Class.java
public class CustomAdapterLV extends BaseAdapter{ String[] resultNames; String[] resultCodes; String[] resultRates; Context context; private static LayoutInflater inflater = null; public CustomAdapterLV(MainActivity mainActivity, String[] names, String[]codes, String[] rates) { resultNames = names; resultCodes = codes; resultRates = rates; context = mainActivity; inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); } @Override public int getCount() { return resultNames.length; } @Override public Object getItem(int position) { return position; } @Override public long getItemId(int position) { return position; } public class ViewHolder{ TextView tvName; TextView tvCode; TextView tvRate; } @Override public View getView(final int position, View convertView, ViewGroup parent) { ViewHolder vh = new ViewHolder(); View rowView; rowView = inflater.inflate(R.layout.activity_custom_lvadapter, null); vh.tvName = (TextView) rowView.findViewById(R.id.currencyNameTV); vh.tvCode = (TextView) rowView.findViewById(R.id.currencyCodeTV); vh.tvRate = (TextView) rowView.findViewById(R.id.currencyRateTV); vh.tvName.setText(resultNames[position]); vh.tvCode.setText(resultCodes[position]); vh.tvRate.setText(resultRates[position]); return rowView; }
currNameArr, currCodeArr, currRateArr are hardcoded in another class, may not add it.
Thanks guys..
