[待解决问题]

 求源码:手机端仿qq的拍照和照片预览功能,求大神指点,我已经实现了拍照功能,但是批量显示,和预览功能不知道用什么控件了,初学安卓菜鸟,求大神指点

代码如下:

/**
 * 利用照相机拍照
 * @author Administrator
 *
 */
public class CameraAcitivity extends Activity{

    SurfaceView sView;
    SurfaceHolder surfaceHolder;
    int screenWidth, screenHeight;
    // 定义系统所用的照相机
    Camera camera;
    //是否在浏览中
    boolean isPreview = false;
    private static final int TAKE_PICTURE = 1;  
    
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.take_pic);
        Button btn = (Button) this.findViewById(R.id.btn_take_pic);
        btn.setOnClickListener(new View.OnClickListener() {
            
            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); //调用摄像头拍照  
                startActivityForResult(intent, TAKE_PICTURE);  
            }
        });
    
    }

    @Override  
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {  
      String filename = "";  
      try {  
        if (resultCode == Activity.RESULT_OK && requestCode == TAKE_PICTURE) {  
          Bundle bundle = data.getExtras();  
          Bitmap bmp = (Bitmap)bundle.get("data");  
          filename = saveImage(bmp);  
      //此处不知道该如何展示多次拍照保存的图片 ImageView show
= (ImageView) findViewById(R.id.show); show.setImageBitmap(bmp); } } catch (Exception err) { err.printStackTrace(); Log.e("Exception", err.getLocalizedMessage()); } } public String saveImage(Bitmap bmp) throws Exception { File file = new File(buildFileName()); // file.createNewFile(); FileOutputStream oStream = new FileOutputStream(file); bmp.compress(Bitmap.CompressFormat.JPEG, 100, oStream); //100是照片质量,0-100,越大越好 oStream.flush(); oStream.close(); return file.getPath(); } public String buildFileName(){ Date now = new Date(); SimpleDateFormat formater = new SimpleDateFormat("yyMMdd_HHmmss"); String newPath = ""; newPath = newPath.replace("/mnt/sdcard", ""); String SDCARD = Environment.getExternalStorageDirectory() + "/"; String basePath = SDCARD + "dier/photo/"; File dir = new File(basePath); dir.mkdirs(); return basePath+formater.format(now) + ".jpg"; } }
