Alert Dialog Two Buttons

问题:

Hello all i have a simple problem i have a alertDialog and i want it to show two buttons i have searched here but it seems the options before don't work anymore and are deprecated.

Anyone know the new way of doing this you can see my code below that doesn't work.

  Button share = (Button) findViewById(R.id.btn_share);
    share.setOnClickListener(new OnClickListener() {   
        public void onClick(View v) {
           // call some other methods before that I guess...
             AlertDialog alertDialog = new AlertDialog.Builder(PasswActivity.this).create(); //Read Update
             alertDialog.setTitle("Uprgade");
             alertDialog.setMessage("Upgrade Text Here");

             alertDialog.setButton("Upgrade", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int which) {

             });
                 alertDialog.setButton("Cancel", new DialogInterface.OnClickListener()    {
                public void onClick(DialogInterface dialog, int which) {

             });



             alertDialog.show();  //<-- See This!


    }
    });

    AlertDialog.Builder builder = new AlertDialog.Builder(activity);

    if (title != null) builder.setTitle(title);

    builder.setMessage(message);

builder.setMessage("Are you sure you want to exit?")
   .setCancelable(false)
   .setPositiveButton("Yes", new DialogInterface.OnClickListener() {
       public void onClick(DialogInterface dialog, int id) {
            MyActivity.this.finish();
       }
   })
   .setNegativeButton("No", new DialogInterface.OnClickListener() {

This should do the trick for you:

Button share = (Button) findViewById(R.id.btn_share);
share.setOnClickListener(new OnClickListener() {   
  public void onClick(View v) {
    // call some other methods before that I guess...
    AlertDialog alertDialog = new AlertDialog.Builder(PasswActivity.this).create(); //Read Update
    alertDialog.setTitle("Uprgade");
    alertDialog.setMessage("Upgrade Text Here");
    alertDialog.setButton( Dialog.BUTTON_POSITIVE, "Upgrade", new DialogInterface.OnClickListener() {
       public void onClick(DialogInterface dialog, int which) {

       });

    alertDialog.setButton( Dialog.BUTTON_NEGATIVE, "Cancel", new DialogInterface.OnClickListener()    {
      public void onClick(DialogInterface dialog, int which) {

      });

    alertDialog.show();  //<-- See This!
  }
});
