Question

我的代码是：

public class GameScreen implements Screen {
    myGame myGame;
    SpriteBatch batch;
    Sprite sprite;
    Texture img;
    Texture imgDialogBoxGood;
    OrthographicCamera camera;

    private Stage stage;
    MainChar mainChar;

    public GameScreen(myGame myGame) {

        this.myGame = myGame;  
        camera = new OrthographicCamera();
        camera.setToOrtho(false, 480, 800);
         mainChar = new MainChar();

        batch = new SpriteBatch();
        stage = new Stage(); 
        stage.getViewport().setCamera(camera);
        stage.addActor(mainChar);
        batch.setProjectionMatrix(camera.combined);
    }

    @Override
    public void render(float delta) {
        Gdx.gl.glClearColor(1, 0, 0, 1);
        Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
        camera.update(); 
        batch.begin(); 
        stage .act(Gdx.graphics.getDeltaTime()); 
       stage.draw();
        batch.end();
    }

    @Override
    public void resize(int width, int height) { }

    @Override
    public void dispose() {
        stage.dispose();
        myGame.dispose();
    }
}

此代码来自androidhive，但我不知道如何解析json（my）。

那么，如何解析json？

试试这个：

    String url = "http://api.giphy.com/v1/gifs/search?q=funny+cat&api_key=dc6zaTOxFJmzC";
    StringRequest stringRequest = new StringRequest(url, new Response.Listener<String>() {
        @Override
        public void onResponse(String response) {
            try {
                JSONObject jsonObject = new JSONObject(response);
                JSONArray jsonArray = jsonObject.getJSONArray("data");
                for (int i = 0; i < jsonArray.length(); i++) {
                    JSONObject jo = jsonArray.getJSONObject(i);
                    // Do you fancy stuff
                    // Example: String gifUrl = jo.getString("url");
                }
            } catch (JSONException e) {
                e.printStackTrace();
            }
        }
    }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            // Anything you want
        }
    });
    RequestQueue requestQueue = Volley.newRequestQueue(getApplicationContext());
    requestQueue.add(stringRequest);

如何用Volley解析JSON？
