发送短信后,android活动自动移至同一活动

我创建了两个活动页面. MainActivity和进行的活动.我正在MainActivity页面中从用户那里获取数据,并且通过意图我正在发送以继续进行活动.

在我输入电话号码的页面上,然后单击发送按钮.它成功发送了消息,但此后我创建了开始活动以移至mainactivity页面.它正在移至主要活动,但几秒钟后会自动开始进行活动.

1.在mainActivity中我正在发送列表

public void Proceed(View view){
        if(planetsList.size()==0){

            Toast.makeText(MainActivity.this, "Please Add Product", Toast.LENGTH_SHORT).show();
            return;

        }
        Intent intent = new Intent(MainActivity.this, Proceed.class);
        intent.putExtra("list_product", planetsList);
        Log.e("gjdgfl",Integer.toString(planetsList.size()));
        startActivity(intent);

    }

2.在继续页面中,编码是

send.setonClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

                String no = mnumber.getText().toString();
                Float netTotal = 0.1f;

                ArrayList<Planet> myList = getIntent().getParcelableArrayListExtra("list_product");

                Log.e("hai1",Integer.toString(myList.size()));
                StringBuilder sb = new StringBuilder();
               for (Planet temp : myList) {
                    sb.append(temp.getName()).append(" ").append(temp.getPerkg()).append("*").append(temp.getTotkg()).append("=").append(temp.getTotamt()).append("\n");
                   netTotal += temp.getTotamt();
                }
                sb.append("Total Amount is -"+netTotal);
                System.out.println(sb.toString());
                System.out.println(no);
                String msg = sb.toString();

                Intent intent=new Intent(getApplicationContext(),Proceed.class);
                PendingIntent pi=PendingIntent.getActivity(getApplicationContext(), 0, intent,0);
                SmsManager sms=SmsManager.getDefault();
                sms.sendTextMessage(no, null, msg, pi,null);
                Toast.makeText(getApplicationContext(), "Message Sent successfully!", Toast.LENGTH_LONG).show();



                AlertDialog.Builder builder = new AlertDialog.Builder(Proceed.this);
                builder.setTitle("Confirmation");
                builder.setMessage("Message Sent Successfully")
                        .setCancelable(false)
                        .setPositiveButton("OK", new DialogInterface.OnClickListener() {
                            public void onClick(DialogInterface dialog, int id) {

                               Intent intent1 = new Intent(Proceed.this,MainActivity.class);
                                intent1.putExtra("exit_on_sent", true);
                                startActivity(intent1);

                            }
                        });
                AlertDialog alert = builder.create();
                alert.show();

}

解决方法:

将PendingIntent类更改为MainActivity,在发送短信后它将重定向到MainActivity.

Intent intent=new Intent(getApplicationContext(),MainActivity.class);
PendingIntent pi=PendingIntent.getActivity(getApplicationContext(), 0, intent,0);
SmsManager sms=SmsManager.getDefault();
