Parsing JSON-formatted data in Android

Package Com.tony.json;

Import android.app.Activity;
Import Android.os.Bundle;
Import Android.view.View;
Import Android.widget.Button;

public class Jsonactivity extends Activity {
/* Called when the activity is first created. /

private String jsonData = "[{\"name\":\"zhangsan\",\"age\":22},{\"name\":\"lisi\",\"age\":23}]";  private Button jsonButton;  @Override  public void onCreate(Bundle savedInstanceState) {      super.onCreate(savedInstanceState);      setContentView(R.layout.main);      jsonButton = (Button) findViewById(R.id.json_button);      jsonButton.setOnClickListener(new View.OnClickListener() {          @Override          public void onClick(View v) {              JsonUtils jsonUtils = new JsonUtils();              jsonUtils.parseJson(jsonData);          }      });  }  

}

The main parsing of this class is the JSON array:

Java Code Collection Code
Package Com.tony.json;

Import java.io.IOException;
Import Java.io.StringReader;

Import Android.util.Log;

Import Com.google.gson.stream.JsonReader;

public class Jsonutils {
private static final String TAG = "Jsonutils";

public void parseJson(String jsonData){      JsonReader reader = new JsonReader(new StringReader(jsonData));      try {          reader.beginArray();    // 开始解析数组          while (reader.hasNext()) {              reader.beginObject();   // 开始解析对象              while (reader.hasNext()) {                  String tagName = reader.nextName(); // 得到键值对中的key                  if (tagName.equals("name")) {   // key为name时                      Log.i(TAG, "name--------->" + reader.nextString());  // 得到key中的内容                  }else if (tagName.equals("age")) {  // key为age时                      Log.i(TAG, "age--------->" + reader.nextInt());  // 得到key中的内容                  }              }              reader.endObject();          }          reader.endArray();      } catch (IOException e) {          e.printStackTrace();      }  }  

}
