请尝试此代码....
弹出对话框的类
if (condition) {
showAlertDialog(Activityname.this, "Internet Connection",
"You have internet connection", true);
} else {
showAlertDialog(Activityname.this, "No Internet Connection",
"You don't have internet connection.", false);
}
showdailog 的方法声明
public void showAlertDialog(Context context, String title, String message, Boolean status) {
AlertDialog alertDialog = new AlertDialog.Builder(context).create();
// Setting Dialog Title
alertDialog.setTitle(title);
// Setting Dialog Message
alertDialog.setMessage(message);
// Setting alert dialog icon
alertDialog.setIcon((status) ? R.drawable.success : R.drawable.fail);
// Setting OK Button
alertDialog.setButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
}
});
// Showing Alert Message
alertDialog.show();
}
}
