Question

我想通过从JSON检索数据来创建列表项，但它失败了，日志聊天是：

无法找到从方法'android.graphics.drawable.RippleDrawable'引用的课程android.support.v7.widget.AppCompatImageHelper.hasOverlappingRendering
解析数据org.json.JSONException时出错：title`

这是我的JSON：

{
"berita": [
    {
        "id_berita": "1",
        "judul_berita": "abcdefgh",
        "gambar_berita": "media.jpg",
        "isi_berita": "arsgrdgrdgrdgrfdrffffffffffrvfsffsfsfsf"
    },
    {
        "id_berita": "2",
        "judul_berita": "ijklmnopqrst",
        "gambar_berita": "back.jpg",
        "isi_berita": "kbkjcbkjbcjkbckjanckjnakjcbjkabcjkabcjabcjhbcjdbcjdb"
    }
]

这是我的代码

protected Void doInBackground(Void... voids) {
        HttpHandler sh = new HttpHandler();
        String jsonStr = sh.makeServiceCall(url);
        Log.e(TAG, "Response from url : "+jsonStr);
        if(jsonStr != null){
            try{
                JSONObject jsonObject = new JSONObject(jsonStr);

                //getting node json array
                JSONArray berita = jsonObject.getJSONArray("berita");

                //looping semua berita
                for(int i = 0; i < berita.length(); i++){
                    JSONObject c = berita.getJSONObject(i);

                    String id_berita = c.getString("id_berita");
                    String judul_berita = c.getString("judul_berita");

                    HashMap<String, String> Berita = new HashMap<>();
                    Berita.put("id_berita", id_berita);
                    Berita.put("judul_berita", judul_berita);

                }
            }
            catch (final JSONException e){
                Log.e(TAG, "JSON parsing error : "+e.getMessage());
                runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        Toast.makeText(BeritaActivity.this, "JSON parsing error"+e.getMessage(), Toast.LENGTH_SHORT).show();
                    }
                });
            }

        }else {
            Log.e(TAG, "Tidak bisa mendapat JSON dari server");
            runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    Toast.makeText(BeritaActivity.this, "Tidak bisa mendapat JSON dari server", Toast.LENGTH_SHORT).show();
                }
            });
        }

        return null;
    }

    @Override
    protected void onPostExecute(Void aVoid) {
        super.onPostExecute(aVoid);
        if(pDialog.isShowing()){
            pDialog.dismiss();
        }
        ListAdapter adapter = new SimpleAdapter(
                BeritaActivity.this, beritaList,
                R.layout.list_item, new String[]{"judul_berita"},
                new int[]{R.id.judulBerita});
        lv.setAdapter(adapter);
    }
}
