基本警报对话框

    AlertDialog.Builder builder = new AlertDialog.Builder(context);
    //Set Title
    builder.setTitle("Reset...")
            //Set Message
            .setMessage("Are you sure?")
            //Set the icon of the dialog
            .setIcon(drawable)
            //Set the positive button, in this case, OK, which will dismiss the dialog and do everything in the onClick method
            .setPositiveButton(android.R.string.ok, new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialogInterface, int i) {
                    // Reset
                }
            });
    AlertDialog dialog = builder.create();
    //Now, any time you can call on:
    dialog.show();
    //So you can show the dialog.
