android - 警报对话框两个按钮

Question

大家好，我有一个简单的问题，我有一个 alertDialog，我希望它显示我在这里搜索过的两个按钮，但似乎之前的选项不再起作用并且已被弃用。

任何人都知道执行此操作的新方法，您可以在下面看到我的代码不起作用。

  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!


    }
    });

Adding Buttons

AlertDialog.Builder builder = new AlertDialog.Builder(this);
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() {
       public void onClick(DialogInterface dialog, int id) {
            dialog.cancel();
       }
   });
AlertDialog alert = builder.create();
alert.show();
