什么是Gson?
Gson 是Google解析Json的一个开源框架,同类的框架还有fastJson、JackJson等等。
怎么实例化?
Gson gson = new Gson();或者Gson gson = new GsonBuilder().create();
把要解析的文件复制到assets
如果乱码看一下你的txt编码格式是否是UTF-8的
TypeToken是gson提供的数据类型转换器
my
package com.example.wangye.androidgj_class9;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.util.Log;
import com.google.gson.Gson;
import java.io.ByteArrayOutputStream;
import java.io.InputStream;
public class MainActivity extends AppCompatActivity {
Gson gson;
String json;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
gson = new Gson();
getDataByAssets();
News news = gson.fromJson(json,News.class);
for (int i = 0; i < news.getResult().size(); i++) {
Log.d("title",news.getResult().get(i).getTitle());
}
}
public void getDataByAssets(){
try {
//可以此方法来加载assets里面的data.txt获得输入流
//然后通过ByteArrayOutputStream的字节输出流.tostring返回Json的代码格式
InputStream is = getAssets().open("data.txt");
ByteArrayOutputStream bs = new ByteArrayOutputStream();
byte buffer[] = new byte[512];
int length = -1;
while( ( length = is.read(buffer) ) != -1){
bs.write(buffer,0,length);
bs.flush();
}
is.close();
bs.close();
json = bs.toString();
} catch (Exception e) {
e.printStackTrace();
}
}
}
想下载一个GsonFormat的插件

然后可以按快捷键Alt+s跳出框,输入Json的数据

生成数据要建一个Bean类
