android – 具有确定/取消按钮的AlertDialog

String msg = "Connessione lenta o non funzionante";
            AlertDialog alertDialog;
            alertDialog = new AlertDialog.builder(HomePage.this).create();
            alertDialog.settitle("Timeout connessione");
            alertDialog.setmessage(msg);
            alertDialog.show();

您可以使用AlertDialog.builder.setPositiveButton和AlertDialog.builder.setNegativeButton,两者都不被弃用( see the documentation)：

new AlertDialog.builder(HomePage.this)
        .settitle("Timeout connessione")
        .setmessage("Connessione lenta o non funzionante")
        .setNegativeButton(android.R.String.cancel,null) // dismisses by default
        .setPositiveButton(android.R.String.ok,new OnClickListener() {
            @Override public void onClick(DialogInterface dialog,int which) {
                // do the ackNowledged action,beware,this is run on UI thread
            }
        })
        .create()
        .show();
