My problem is this, I have an Activity that calls methods from a common Java class to perform operations.
Now I've come up with the need for one of these methods to be AlertDialog , I've researched in several places and can not find a solution, can anyone help?
Create a method in your separate class with the following parameters:
public static void showAlert(Context context, String title, String message){
AlertDialog alertDialog = new AlertDialog.Builder(context).create();
alertDialog.setTitle(title);
alertDialog.setMessage(message);
alertDialog.setButton(AlertDialog.BUTTON_NEUTRAL, "OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
});
alertDialog.show();
}
Then to call it, do the following:
SuaClasseOndeEstaoMetodo.showAlert(this, "Erro", "A imagem não pode ser carregada");
Create a class:
public class Message {
public static void Alert(Context context, String Mensagem) {
AlertDialog.Builder alertDialog = new AlertDialog.Builder(context);
//ADICIONANDO UM TITULO A NOSSA MENSAGEM DE ALERTA
alertDialog.setTitle(R.string.app_name); //ou alertDialog.setTitle("Nome do app");
//MENSAGEM A SER EXIBIDA
alertDialog.setMessage(Mensagem);
//CRIA UM BOTÃO COM O TEXTO OK SEM AÇÃO
alertDialog.setPositiveButton("OK", null);
//MOSTRA A MENSAGEM NA TELA
alertDialog.show();
}
}
And to "call" Alert use:
Message.Alert(this, this.getString(R.string.save));
//ou Message.Alert(this, "Mensagem Desejada");
Note: If you use strings , in values \ strings.xml add:
<string name="save">Salvo com Sucesso!</string>
<string name="app_name">Nome do App</string>
