Android 调用意图时出错

调用intent

startActivity（新intent（this，Advogado1.class））时出错

，如何正确调用此

intent

            AlertDialog.Builder alert = new AlertDialog.Builder(this);

            alert.setTitle("Atenção");
            alert.setMessage("Digite o Numero da OAB");

            // Set an EditText view to get user input
            final EditText input = new EditText(this);
            alert.setView(input);

            alert.setPositiveButton("Ok",
                    new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog,
                                int whichButton) {

                            int oab = Integer.parseInt(input.getText()
                                    .toString());
                            // Do something with value!

                            if (oab == 1) {

                                startActivity(new Intent(this, Advogado1.class));
                            }

                        }
                    });

            alert.setNegativeButton("Cancelar",
                    new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog,
                                int whichButton) {
                            // Canceled.
                        }
                    });

            alert.show();

呼吁,

startActivity(new Intent(this, Advogado1.class));

不应该使用“this”，它应该使用

startActivity(new Intent(NameOfYourActivity.this, Advogado1.class));

因为

此

引用了扩展

DialogInterface.OnClickListener

的匿名类，而不是您的

活动

类。意图需要调用方类作为活动的实例。
