AlertDialog无法解析或不是字段

Question

I'm getting the following errors,i did exactly(afaik) as a guy in a tutorial but i still get the errors : "cannot make a static reference to the non static method show() from the type dialog" at " AlertDialog.show();" "AlertDialog cannot be resolved or is not a field" at "AlertDialog.alertDialog = dialogBuilder.create();"

Here's my code :

public Button paginanoua;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    paginanoua = (Button) findViewById(R.id.paginanoua);

    paginanoua.setOnClickListener(this);

}

public void onClick(View view) {
    ShowDialog();
}

private void ShowDialog() {

    AlertDialog.Builder dialogBuilder = new AlertDialog.Builder(this);
    dialogBuilder.setTitle("Pagina noua..");
    dialogBuilder.setMessage("Sigur doriti o pagina noua?");
    dialogBuilder.setPositiveButton("Da",
            new DialogInterface.OnClickListener() {

                public void onClick(DialogInterface dialog, int which) {

                    Toast.makeText(getApplicationContext(),
                            "Am inceput o lista noua", Toast.LENGTH_SHORT)
                            .show();
                }

            });
    dialogBuilder.setNegativeButton("Nu",
            new DialogInterface.OnClickListener() {

                @Override
                public void onClick(DialogInterface dialog, int which) {

                    Toast.makeText(getApplicationContext(),
                            "Ramanem la lista curenta", Toast.LENGTH_SHORT)
                            .show();
                }
            });
    AlertDialog.alertDialog = dialogBuilder.create();
    AlertDialog.show();
}

What did i do wrong ?

Answer 1

You didn't declare a name to your variable.

Change it with :

AlertDialog alertDialog = dialogBuilder.create();
alertDialog.show();

Answer 2

Try this

Replace

   AlertDialog.alertDialog = dialogBuilder.create();
   AlertDialog.show();  

By this

   AlertDialog alertDialog = dialogBuilder.create();
   alertDialog.show();

or just as suggested by @blackbelt

   dialogBuilder.show();
