     capturedImageButton.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) {

       startActivityForResult(photoCaptureIntent, requestCode); 
      } 
     }); 
    } 

    @Override 
    protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
     super.onActivityResult(requestCode, resultCode, data); 
     if(this.requestCode == requestCode && resultCode == RESULT_OK){ 
      Bitmap bitmap = (Bitmap)data.getExtras().get("data"); 

      String partFilename = currentDateFormat(); 
      storeCameraPhotoInSDCard(bitmap, partFilename); 


     } 
    } 

    private String currentDateFormat(){ 
     SimpleDateFormat dateFormat = new SimpleDateFormat("yyyyMMdd_HH_mm_ss"); 
     String currentTimeStamp = dateFormat.format(new Date());

    } 

    private void storeCameraPhotoInSDCard(Bitmap bitmap, String currentDate){ 
     File outputFile = new File(Environment.getExternalStorageDirectory(), "photo_" + currentDate + ".jpg"); 
     try { 
      FileOutputStream fileOutputStream = new FileOutputStream(outputFile); 
      bitmap.compress(Bitmap.CompressFormat.JPEG, 100, fileOutputStream); 
      fileOutputStream.flush(); 
      fileOutputStream.close(); 
     } catch (FileNotFoundException e) { 
      e.printStackTrace(); 
     } catch (IOException e) { 
      e.printStackTrace(); 
     }

您应该实现一个使用线程的可运行接口。这样，您可以调用OnClick方法的函数，然后调用Thread.sleep（timeinmilliseconds），然后再次根据需要调用onClick方法中的函数。

下面是如何使用线程的例子：
