java - 在Android中完成count_downtimer后显示自定义对话框消息

我正在为有趣的游戏实现倒数计时器。一分钟结束后，我想显示自定义对话框。我尝试过，当运行该应用程序时，它可以正常运行，但出现致命异常之类的异常。我尝试了很多，每次都会得到例外。

这是我的活动中倒数计时器的代码。

new CountDownTimer(60*1*1000, 1000)
        {

            @Override
            public void onTick(long millisUntilFinished)
            {
                textView_TimerValue.setText("seconds remaining : "
                        + millisUntilFinished / 1000);
            }

       @Override
       public void onFinish()
            {

           textView_TimerValue.setText("TIME IS OVER");
            //tell the Dialog to use the dialog.xml as it's layout description
                dialog = new Dialog(Gsk_Demo.this);

                dialog.setContentView(R.layout.dialogbox_);

                TextView txt = (TextView) dialog.findViewById(R.id.textV);
                txt.setText("Your Time Is Over.Click Next.");

                Button dialogButton1 = (Button) dialog.findViewById(R.id.buttonDialog_Next);

                dialogButton1.setOnClickListener(new OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        Intent i=new Intent(Gsk_Demo.this , Code_Demo.class);
                        startActivity(i);

                    }
                });

                dialog.show();
            }
        }.start();

这是我的Log cat堆栈跟踪。

最佳答案

试试这个希望这对你有用

final Dialog dialog = new Dialog(context);
                dialog.setContentView(R.layout.camgaldialog);
                dialog.setTitle("Complete action using");
                Button dialogcam = (Button) dialog.findViewById(R.id.Bcam);
                dialogcam.setOnClickListener(new OnClickListener() {

                    @Override
                    public void onClick(View view0) {
                        // TODO Auto-generated method stub
                        Intent i = new Intent(
                                android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
                        startActivityForResult(i, 0);
                        dialog.dismiss();
                    }

                });
                dialog.show();
                break;
