Question

我正在尝试制作一个程序，显示多个带有图片的标题。我查看了stackoverflow，并且无法获得任何适合我的建议。我的所有错误都在私有的无效ShowJSON

        textViewResult.setText(title);//+"\nImagine :\t"+ image);
        //int id = >getResources().getIdentifier("http://192.168.1.254/2015/380panel/uploads/images>/sm/"+ image, null, null);
        //ImageView1.setImageURI(id);
        >Picasso.with(this).load("http://192.168.1.254/2015/380panel/uploads/images/sm/+ image).into(ImageView1);

    }

我的错误是：

Cannot resolve constructor JSONobject(java.lang.Integer)

它在JSONObject jsonObject = new JSONObject(response);

行

Answer 1

将showJson（整数响应）更改为

showJson(String response){
String title="";
String image = "";
try {
    JSONArray jarray=new JSONArray(response);
    for( int i= 0;i<jarray.length();i++){
    JSONObject jsonObject = jarray.getJSONObject(i);
    JSONArray result = jsonObject.getJSONArray(ConfigRec.JSON_ARRAY);
    JSONObject androidData = result.getJSONObject(0);
    title = androidData.getString(ConfigRec.KEY_TITLE);
    image = androidData.getString(ConfigRec.KEY_IMAGE);
}} catch (JSONException e) {
    e.printStackTrace();
}
    textViewResult.setText(title);//+"\nImagine :\t"+ image);
    //int id = >getResources().getIdentifier("http://192.168.1.254/2015/380panel/uploads/images>/sm/"+ image, null, null);
    //ImageView1.setImageURI(id);
    >Picasso.with(this).load("http://192.168.1.254/2015/380panel/uploads/images/sm/+ image).into(ImageView1);

}
