如何指定相同的活动而不是第二个活动 [英] how to intent the same activity instead of second activity

问题描述

我想要进行相同的活动，例如MainActivity-> MainActivity而不是MainActivity-> SecondActivity

I want to intent same activity such as MainActivity->MainActivity instead of MainActivity->SecondActivity

这是我的代码，但是它不起作用，它将停止我的应用程序，以及如何对其进行修复

Her is my code, but it doesn't work, it will stop my app, how to fix it

 public class AddasMessage extends AsyncTask<AddMessage,Long,JSONArray>
{
    ProgressDialog dialog = new ProgressDialog(FriendDetailsActivity.this);

        dialog.setMessage("Adding...");
        dialog.show();
    }
    @Override
    protected JSONArray doInBackground(AddMessage... params) {

        // it is executed on Background thread

        return params[0].AddtobeMessage();


    }

    @Override
    protected void onPostExecute(JSONArray jsonArray) {
        Log.i("Main activity", String.valueOf(jsonArray));
        dialog.dismiss();

        Intent intent = new Intent(getBaseContext(), FriendDetailsActivity.class);
       intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        startActivity(intent);
        Context context = getApplicationContext();
        CharSequence text = "You are success to send the message!";
        int duration = Toast.LENGTH_SHORT;

        Toast toast = Toast.makeText(context, text, duration);
       toast.show();



    }



}

推荐答案

我认为您想刷新我们的活动，请尝试

I think you want to refresh our activity, try this

finish();
startActivity(getIntent());

或尝试

Intent intent = getIntent();
    finish();
    startActivity(intent);
