窗口关闭后，如何在10秒内打开

Question

对话框在10秒后打开，不连续，我想在关闭后再等待10秒

如何制作

1. 首先在10秒内打开
2. 我在5秒钟后点击关闭按钮
3. 其次，5秒后再次打开
4. 关闭后我想要10秒钟重新开始

代码在这里

final Dialog dialog = new Dialog(this);
    final Handler h = new Handler();
    final int delay = 10000;

    h.postDelayed(new Runnable() {
        public void run() {
            //do something
            dialog.setContentView(R.layout.custom);
            dialog.setTitle("Title...");

            Button dialogButton = (Button) dialog.findViewById(R.id.dialogButtonOK);

            dialogButton.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    dialog.dismiss();

                }
            });

            dialog.show();
            h.postDelayed(this, delay);
        }
    }, delay);

在取消之前等待10秒

final Dialog dialog = new Dialog(this);
    final Handler h = new Handler();
    final int delay = 10000;

    h.postDelayed(new Runnable() {
        public void run() {
            //do something
            dialog.setContentView(R.layout.custom);
            dialog.setTitle("Title...");

            Button dialogButton = (Button) dialog.findViewById(R.id.dialogButtonOK);

            dialogButton.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                     h.postDelayed(new Runnable() {
                      public void run() {
                         //this method will execute with a delay of after 10 seconds
                         dialog.dismiss();
                      }, delay);
                }
            });

            dialog.show();
            h.postDelayed(this, delay);
        }
    }, delay);

首先为Handler声明一个全局变量，以便从Thread更新UI控件，如下所示

//time for 60 seconds

int time = 0;

Handler mHandler = new Handler();


 public void showDialog(){


    new Thread(new Runnable() {
        @Override
        public void run() {
            // TODO Auto-generated method stub
            while (true) {
                try {
                    Thread.sleep(10000);
                    mHandler.post(new Runnable() {

                        @Override
                        public void run() {


                            final Dialog dialog = new Dialog(this);
                            dialog.setContentView(R.layout.custom);
                            dialog.setTitle("Title...");

                            Button dialogButton = (Button) dialog.findViewById(R.id.dialogButtonOK);

                            dialogButton.setOnClickListener(new View.OnClickListener() {
                                @Override
                                public void onClick(View v) {
                                    dialog.dismiss();
                                 if(time<=60){
                                 time += 10;
                                 showDialog();

                                 }
                                }
                            });

                            dialog.show();

                        }
                    });
                } catch (Exception e) {
                    // TODO: handle exception
                }
            }
        }
    }).start();
}

我是这样做的，但应用程序已停止

public class MainActivity extends AppCompatActivity { Handler mHandler = new Handler();

 Dialog dialog = new Dialog(this);

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
}






public void showDialog(){

    new Thread(new Runnable() {
        @Override
        public void run() {
            // TODO Auto-generated method stub
            while (true) {
                try {
                    Thread.sleep(10000);
                    mHandler.post(new Runnable() {

                        @Override
                        public void run() {



                            dialog.setContentView(R.layout.custom);
                            dialog.setTitle("Title...");

                            Button dialogButton = (Button) dialog.findViewById(R.id.dialogButtonOK);

                            dialogButton.setOnClickListener(new View.OnClickListener() {
                                @Override
                                public void onClick(View v) {
                                    dialog.dismiss();
                                    showDialog();

                                }
                            });

                            dialog.show();

                        }
                    });
                } catch (Exception e) {
                    // TODO: handle exception
                }
            }
        }
    }).start();
}
}
