Question

我用这段代码在android中生成警告对话框。但是我想要左边的是按钮，右边没有按钮。我怎么能这样做？

public class App {

  public static void main(String[] args) {
    ThrdO to=new ThrdO();
    Thread t1=new Thread(to);

    ThredE te=new ThredE();
    Thread t2=new Thread(te);
    t1.start();


    t2.start();
 }

}

public class ThrdO implements Runnable{

  PrintCl pcl =new PrintCl();

  @Override
  public void run() {
    for(int i=0;i<10;i+=2)
    pcl.Even(i);    
  }
}


public class ThredE implements Runnable {

    PrintCl pcl =new PrintCl();

    @Override
    public void run() {
      for(int i=1;i<10;i+=2)
        try {
          pcl.odd(i);
        } catch (InterruptedException e) {
          // TODO Auto-generated catch block
          e.printStackTrace();
        }   
     }

public class PrintCl {
    public void Even(int n) {
      synchronized (this) {
        System.out.println(n);
        this.notifyAll();
        try {
            this.wait();
        } catch (InterruptedException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
      }         
    }

    public void odd(int n) throws InterruptedException {

        synchronized (this) {
          System.out.println(n);
          this.notifyAll();
          this.wait();  
        }
    }
}

您可以根据自己的意愿更改正面按钮中的文字，并在其中编写任何代码。

AlertDialog.Builder    builder = new    AlertDialog.Builder(
                            getApplicationContext());
                    builder.setCancelable(true);
                    builder.setTitle("Title");
                    builder.setInverseBackgroundForced(true);
                    builder.setPositiveButton("No",
                            new     DialogInterface.OnClickListener() {
                                @Override
                                public   void onClick(DialogInterface dialog,
                                        int which) {
                                    dialog.dismiss();
                                }
                            });
                    builder.setNegativeButton("Yes",
                            new DialogInterface.OnClickListener() {
                                @Override
                                public void onClick(DialogInterface dialog,
                                        int which) {
                                    dialog.dismiss();
                                }
                            });
                    AlertDialog alert = builder.create();
                    alert.show();

def receive = runRoute(routes) orElse {
  case CleanupFile(file) => Try(file.delete())
}
