android - 一段时间后，自动关闭窗口弹出。怎么做

我正试图自动关闭我的膨胀弹出窗口后，一些秒与一些时间计数器。我不知道怎么用计数计时器（5秒）。

  LayoutInflater inflater = (LayoutInflater)screen.getSystemService(screen.LAYOUT_INFLATER_SERVICE);
                    layout =  inflater.inflate(R.layout.log_viewer,null);

                    AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
                    builder.setCancelable(true);
                    builder.setView(layout);

                    AlertDialog alertDialog = builder.create();
                    alertDialog.show();

                    Button btn0= (Button)layout.findViewById(R.id.btn0);
                    Button btn1= (Button)layout.findViewById(R.id.btn1);
                    Button btn2= (Button)layout.findViewById(R.id.btn2);
                    btn0.setOnClickListener(new OnClickListener() {

                        @Override
                        public void onClick(View v) {

                            Intent i =new Intent(Main_Activity.this,Act.class);
                            startActivity(i);
                            overridePendingTransition(R.anim.animation,R.anim.animation2);
                        }
                    });
                    btn1.setOnClickListener(new OnClickListener() {

                        @Override
                        public void onClick(View v) {

                            Intent i =new Intent(Main_Activity.this,Activity2.class);
                            startActivity(i);
                            overridePendingTransition(R.anim.animation,R.anim.animation2);
                        }
                    });
                    btn2.setOnClickListener(new OnClickListener() {

                        @Override
                        public void onClick(View v) {

                            Intent i =new Intent(Main_Activity.this,Activity1.class);
                            startActivity(i);
                            overridePendingTransition(R.anim.animation,R.anim.animation2);
                        }
                    });


                    WindowManager.LayoutParams lp = new WindowManager.LayoutParams();
                    Window window = alertDialog.getWindow();
                    lp.copyFrom(window.getAttributes());

                    lp.width = WindowManager.LayoutParams.MATCH_PARENT;
                    lp.height = WindowManager.LayoutParams.WRAP_CONTENT;
                    window.setAttributes(lp);

最佳答案

您是否考虑在自定义布局中使用Toast？请参见Android上的Toast documentation。
以开发者网站为例。
或者您可以使用Handler

Handler handler = new Handler();
handler.postDelayed(new Runnable() {

    @Override
    public void run() {
        // close your dialog
        alertDialog.dismiss();
    }

}, 10000); // 10,000 ms delay
