我想在我的字符串 JsonObject 中获取值

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{"状态"："1"，"结果"："真"( 但是我不能做，如果"状态"意味着我无法在状态中获得"1"的值。

Answer 1

两个错误

1. 将整数和布尔值作为字符串获取
2. 将字符串与==进行比较

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

">

=="是引用比较。 因此，将"=="替换为等于((

status.equals("1")

Answer 3

我希望这对你有用。

通过使用字符串

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.
}
