android 添加视频、图片、录音上传（一）

实现一个功能，上报信息，可以添加视频、图片、录音。调用系统相机，所以每次只能选择一张图片。

使用的图片处理方式

    //拍照        add_photo.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                if (commitId.equals("0")) {                    Toast.makeText(getApplicationContext(), "请先保存上面的信息", 0).show();                    return;                }else{                    Intent local = new Intent();                    local.setType("image/*");                    local.setAction(Intent.ACTION_GET_CONTENT);                    startActivityForResult(local, 11);                }            }        });        //录像        add_video.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                if (commitId.equals("0")) {                    Toast.makeText(getApplicationContext(), "请先保存上面的信息", 0).show();                    return;                }else{                    Intent intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);                        intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 0);                        startActivityForResult(intent, 10);                 }            }        });

拍照和视频的处理

@Override    protected void onActivityResult(int requestCode, int resultCode, Intent data) {        if(resultCode== Activity.RESULT_OK){                switch(requestCode) {            case 10:                Uri uriVideo = data.getData();                    Cursor cursors=this.getContentResolver().query(uriVideo, null, null, null, null);                    if (cursors.moveToNext()) {                            /* _data：文件的绝对路径 ，_display_name：文件名 */                        videoPath = cursors.getString(cursors.getColumnIndex("_data"));                            Toast.makeText(this, videoPath, Toast.LENGTH_SHORT).show();                         //保存视频路径                        imagelist.add(videoPath);                        setImageGrideValue();                   }                    break;            case 11:                Uri uri = data.getData();                Log.e(TAG, "uri = " + uri);                try {                    String[] pojo = { MediaStore.Images.Media.DATA };                    Cursor cursor = managedQuery(uri, pojo, null, null, null);                    if (cursor != null) {                        ContentResolver cr = this.getContentResolver();                        int colunm_index = cursor                                .getColumnIndexOrThrow(MediaStore.Images.Media.DATA);                        cursor.moveToFirst();                        String path = cursor.getString(colunm_index);                        /***                         * 这里加这样一个判断主要是为了第三方的软件选择，比如：使用第三方的文件管理器的话，你选择的文件就不一定是图片了，                         * 这样的话，我们判断文件的后缀名 如果是图片格式的话，那么才可以                         */                        if (path.endsWith("jpg") || path.endsWith("png")) {                            srcPath=path;                            //保存图片路径                            imagelist.add(srcPath);                            setImageGrideValue();                        } else {                            alert();                        }                    } else {                        alert();                    }                } catch (Exception e) {                    e.printStackTrace();                }                break;            default:                break;                }            }        super.onActivityResult(requestCode, resultCode, data);    }     private void alert() {            Dialog dialog = new AlertDialog.Builder(this).setTitle("提示")                    .setMessage("您选择的不是有效的图片")                    .setPositiveButton("确定", new DialogInterface.OnClickListener() {                        public void onClick(DialogInterface dialog, int which) {                            srcPath = null;                        }                    }).create();            dialog.show();        }

在页面显示添加的视频和照片列表（视频使用的是默认图片显示）
