如何避免覆盖Android中的背页？

Question

录制多个音频语音并添加一个按钮，以便在录制后返回上一个活动。但经过多次录制并尝试返回上一页，该页面不会直接切换到上一页。如果我录制4个音频语音并尝试转到上一个点击按钮，他将4次显示同一页面并显示4个记录，再次单击显示3，再次单击显示2和最后1然后转到上一个。如何解决这个问题。有人能帮我吗。

这是我的记录活动代码

  imageRecord = (ImageView) findViewById(R.id.image_Record);
        imageRecord.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                clickCount += 1;
                Log.e("clickCount ", " click !!! " + clickCount);

                if (clickCount == 1)
                {
                    btnSaveRecord.setEnabled(false);
                    btnCancelRecord.setEnabled(false);
                    myAudioRecorder = new MediaRecorder();


                    if (vesselId == null) {

                        SimpleDateFormat s = new SimpleDateFormat("ddMMyyyyhhmmss");
                        newAudioFile = 0 + "_" + s.format(new Date()) + ".mp3";
                        Log.e(" newAudioFile ", " = " + newAudioFile);
                        outputFile = baseDir + "/classnkk_audio/" + newAudioFile;

                        } catch (IllegalStateException e) {

                } else if (clickCount == 2)
                {

                Intent i = new Intent(ItemDetail_Record.this, 
                 AllPost_ItemDetails.class);
                //i.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
                finish();

               uploadrecord(strUploadActivityObjectId);
            }
        });
    }

这是我的另一项活动

imgView_BackToAllPost.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    Intent i = new Intent(AllPost_ItemDetails.this , CustomActionActivity.class);
                    finish();
                    startActivity(i);
                }
            });

    imgButn_AudioRecord.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    Intent i = new Intent(AllPost_ItemDetails.this, ItemDetail_Record.class);
                    i.putExtra("DetailView_ActivityId", strActivityId);
                    startActivityForResult(i, 1234);
                }
            });
