您可以为此使用AlertDialog，并使用它的Builder类构造一个AlertDialog。下面的例子使用默认的构造函数，它只接受Context，因为对话框将从传入的Context继承适当的主题，但是如果你想这样做，还有一个构造函数允许你指定一个特定的主题资源作为第二个参数。

new AlertDialog.Builder(context)
    .setTitle("Delete entry")
    .setMessage("Are you sure you want to delete this entry?")

    // Specifying a listener allows you to take an action before dismissing the dialog.
    // The dialog is automatically dismissed when a dialog button is clicked.
    .setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int which) { 
            // Continue with delete operation
        }
     })

    // A null listener allows the button to dismiss the dialog and take no further action.
    .setNegativeButton(android.R.string.no, null)
    .setIcon(android.R.drawable.ic_dialog_alert)
    .show();

David Hedlund发布的代码给了我错误:

无法添加窗口-空令牌无效

如果你得到同样的错误，请使用下面的代码。它的工作原理!

runOnUiThread(new Runnable() {
    @Override
    public void run() {

        if (!isFinishing()){
            new AlertDialog.Builder(YourActivity.this)
              .setTitle("Your Alert")
              .setMessage("Your Message")
              .setCancelable(false)
              .setPositiveButton("ok", new OnClickListener() {
                  @Override
                  public void onClick(DialogInterface dialog, int which) {
                      // Whatever...
                  }
              }).show();
        }
    }
});

试试Kotlin

AlertDialog.Builder(this)
            .setTitle("Title")
            .setPositiveButton("Yes"){ dialog, which ->

            }
            .setNegativeButton("No", null)
            .setMessage("Your given alert message...")
            .show()

new AlertDialog.Builder(context)
    .setTitle("title")
    .setMessage("message")
    .setPositiveButton(android.R.string.ok, null)
    .show();

    LayoutInflater inflater = LayoutInflater.from(HistoryActivity.this);
    final View vv = inflater.inflate(R.layout.dialog_processing_tts, null);
    final AlertDialog.Builder alert = new AlertDialog.Builder(
            HistoryActivity.this);
    alert.setTitle("Delete");
    alert.setView(vv);
    alert.setCancelable(false)
            .setPositiveButton("Delete", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    databaseHelperClass.deleteHistory(list.get(position).getID());
                    list.clear();
                    setAdapterForList();

                }
            })
            .setNegativeButton("Cancel",
                    new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog, int id) {
                            dialog.cancel();
                        }
                    });

    final AlertDialog dialog = alert.create();
    dialog.show();
