安卓:在创建和显示AlertDialog之前获取资源ID？

<string name="alert_dialog_message">This is a sample alert dialog.</string>

int messageResourceId = getResources().getIdentifier("alert_dialog_message", "string", getPackageName());

AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setMessage(messageResourceId)
        .setTitle("Alert Dialog")
        .setPositiveButton("OK", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int id) {
                // 点击确定按钮的操作
            }
        })
        .setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int id) {
                // 点击取消按钮的操作
            }
        });
AlertDialog dialog = builder.create();
dialog.show();
