JSON数据的解析
例子：

public class ParseJsonActivity extends Activity{
private String jsonData="[{\"name\":\"michael\",\"age\":20},{\"name\":\"mike\",\"age\":22}]";
private Button button;
public void onCreate(Bundle saveInstanceState){
super.onCreate(saveInstanceState);
setContentView(R.layout.main);
button=(Button)findViewById();
button.setOnClickListener(new ButtonListener());
}
private class ButtonListener implements OnClickListener{
public void onClick(View v){
JsonUtils jsonUtils=new JsonUtils();
jsonUtils.parseJson(jsonData);
}
}
}


public class JsonUtils{
public void parseJson(String jsonData){
try{
JsonReader reader = new JsonReader(new StringReader(jsonData));
reader.beginArray();
while(reader.hasNext()){
reader.beginObject();
while(reader.hasNext()){
String tagName=reader.nextName();
if(tagName.equals("name")){
System.out.println("name--->"+reader.nextString());
}else if(tagName.equals("age")){
System.out.println("age--->"+reader.nextInt());
}
}
reader.endObject();
}
reader.endObject();
}catch(Exception e){
e.printStackTrace();
}
}
}
