Android Parsing JSON

1. Parse the live JSON response from http://beer.androidph.com/beerws. See App Engine Generating JSON.

2. Use the code from Android Networking Tutorial

3. JSON Parser Code

JSONArray parseArray = new JSONArray(message);
for (int i = 0; i < jo =" parseArray.getJSONObject(i);

4. Modify nextscreen.xml of the source code from #2.

5. Modify NextScreen.java from source code in #2 or Android Networking Tutorial

public class NextScreen extends Activity implements OnClickListener {
 private Button btnBack;

 private ViewGroup.LayoutParams layoutName;
 private ViewGroup.LayoutParams layoutAddress;
 private ViewGroup.LayoutParams layoutPrice;
 private ViewGroup.LayoutParams layoutLastCallTime;
 private ViewGroup.LayoutParams layoutLocation;

 private String message;
 private LinearLayout linearLayout;
 private LinearLayout linearInnerLayout;

 @Override
 public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.nextscreen);
  initComponents();
 }

 public void initComponents() {

  linearLayout = (LinearLayout) findViewById(R.id.linearLayout);
  linearInnerLayout = (LinearLayout) linearLayout.getChildAt(0);

  layoutName = ((TextView) linearInnerLayout.getChildAt(0))
    .getLayoutParams();
  layoutAddress = ((TextView) linearInnerLayout.getChildAt(1))
    .getLayoutParams();
  layoutPrice = ((TextView) linearInnerLayout.getChildAt(2))
    .getLayoutParams();
  layoutLastCallTime = ((TextView) linearInnerLayout.getChildAt(3))
    .getLayoutParams();
  layoutLocation = ((TextView) linearInnerLayout.getChildAt(4))
    .getLayoutParams();

  message = getIntent().getStringExtra(NetworkConnection.NC_RESPONSE);
  
  LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(
    LinearLayout.LayoutParams.FILL_PARENT,
    LinearLayout.LayoutParams.WRAP_CONTENT);
  
  try {
   JSONArray parseArray = new JSONArray(message);
   for (int i = 0; i < parseArray.length(); i++) {
    JSONObject jo = parseArray.getJSONObject(i);
    
    LinearLayout newRow = new LinearLayout(this);
    newRow.setLayoutParams(linearInnerLayout.getLayoutParams());
    
    String name = jo.getString("name") + " | ";
    TextView curTvName = new TextView(this);
    curTvName.setText(name);
    curTvName.setLayoutParams(layoutName);
    
    String address = jo.getString("address") + " | ";
    TextView curTvAddress = new TextView(this);
    curTvAddress.setText(address);
    curTvAddress.setLayoutParams(layoutAddress);
    
    String price = jo.getString("price") + " | ";
    TextView curTvPrice = new TextView(this);
    curTvPrice.setText(price);
    curTvPrice.setLayoutParams(layoutPrice);
    
    String lastCallTime = jo.getString("lastCallTimeString") + " | ";
    TextView curTvLastCallTime = new TextView(this);
    curTvLastCallTime.setText(lastCallTime);
    curTvLastCallTime.setLayoutParams(layoutLastCallTime);
    
    String location = jo.getString("latitude") + "," + jo.getString("longitude");
    TextView curTvLocation = new TextView(this);
    curTvLocation.setText(location);
    curTvLocation.setLayoutParams(layoutLocation);
    
    newRow.addView(curTvName);
    newRow.addView(curTvAddress);
    newRow.addView(curTvPrice);
    newRow.addView(curTvLastCallTime);
    newRow.addView(curTvLocation);
    
    linearLayout.addView(newRow, new LinearLayout.LayoutParams(
      LinearLayout.LayoutParams.FILL_PARENT,
      LinearLayout.LayoutParams.WRAP_CONTENT));
   }
  } catch (JSONException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  }
 }

 @Override
 public void onClick(View v) {
  if (v == btnBack) {
   finish();
  }
 }
}
