Question

    try {
        JSONObject jobj = new JSONObject(response);
        String status = jobj.getString("status");
        String error = jobj.getString("result");

        if(status == "1"){
            builder.setTitle("Server Message");
            builder.setMessage("Please validate your ID in registered email.");

        }else if(status == "0")
        {
            builder.setTitle("Server Message");
            builder.setMessage(error);
        }else{
            builder.setTitle("Server Message");
            builder.setMessage(response);
        }

    } catch (JSONException e) {
        e.printStackTrace();
    }

    builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            Intent mainIntent = new Intent(RegisterActivity.this, LoginActivity.class);
            startActivity(mainIntent);
        }
    });

    AlertDialog alertDialog = builder.create();
    alertDialog.show();
}

我的回答是{＆＃34;状态＆＃34;：＆＃34; 1＆＃34;，＆＃34;结果＆＃34;：＆＃34; true＆＃34;）但是我无法做到＆＃34; status＆＃34;意味着我无法获得＆＃34; 1＆＃34;在状态内。

Answer 1

两个错误

将整数和布尔值作为字符串
将字符串与==

这样做

int status = jobj.getInt("status");
Boolean error = jobj.getBoolean("result");

if(status == 1){
    builder.setTitle("Server Message");
    builder.setMessage("Please validate your ID in registered email.");
}else if(status == 0) 
{
    ...
    ...

Answer 2

我希望这对你有用。

使用String

 String status = jobj.getString("status");
    String error = jobj.getString("result");

   if(status.equalsIgnoreCase("1")){
      builder.setTitle("Server Message");
     builder.setMessage("Please validate your ID in registered email.");

    }else if(status.equalsIgnoreCase("0")){
        // your other code.
}

Answer 3

＆＃34; ==＆＃34;是参考比较。所以，替换＆＃34; ==＆＃34;等于（）

status.equals("1")

我想在String JsonObject中获取值
