1.拍照后制定位置存儲(chǔ)

Intent getImageByCamera = new Intent("android.media.action.IMAGE_CAPTURE");
capturePath = Constant.IMGPATH + File.separator + System.currentTimeMillis() + ".jpg";
getImageByCamera.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(new File(capturePath))); 

startActivityForResult(getImageByCamera, 1);

2.調(diào)用系統(tǒng)播放器

Photo photo = list.get(i);
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.parse(photo.path), "video/mp4");
startActivity(intent);

3.調(diào)用系統(tǒng)圖庫(kù)顯示圖片

Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.parse("file://" +item.getPath), "image/*");
startActivity(intent);

4.調(diào)用系統(tǒng)相冊(cè)選擇圖片

//調(diào)用相冊(cè)
 //4.0版本之前利用系統(tǒng)相冊(cè)選擇照片調(diào)用這個(gè)方法就可以，4.0之后調(diào)用之后會(huì)左邊會(huì)增加一個(gè)抽屜顯示最近內(nèi)容什么的，此時(shí)返回的uri并不能直接查詢出數(shù)據(jù)
Intent local = new Intent();
local.setType("image/*");
local.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(local, 7);
//兩個(gè)版本的uri對(duì)比

content://com.android.providers.media.documents/document/image%3A228455（4.0之后）
content://com.android.providers.media.documents/document/228455（4.0）

//4.0之后的版本調(diào)用這個(gè)方法，同時(shí)兼容4.0

 ntent local1 = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
local1.setType("image/*");
startActivityForResult(local1, 7);

  @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
            super.onActivityResult(requestCode, resultCode, data);
            Uri uri = data.getData();  
            img.setImageURI(uri);  
            ContentResolver cr = this.getContentResolver();  
            Cursor c = cr.query(uri, null, null, null, null);  
            c.moveToFirst();  
            //這是獲取的圖片保存在sdcard中的位置  
            srcPath = c.getString(c.getColumnIndex("_data"));  
            System.out.println(srcPath+"----------保存路徑2");  
    }

5.調(diào)用媒體庫(kù)選擇視頻

Intent local = new Intent();
       local.setType("video/*;image/*");
       local.setAction(Intent.ACTION_GET_CONTENT);
       startActivityForResult(local, 8);

@Override  
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {  
        // 選取圖片的返回值  
        if (requestCode == 1) {  
            //  
            if (resultCode == RESULT_OK) {  
                Uri uri = data.getData();  
                Cursor cursor = getContentResolver().query(uri,     null, null,  null, null);  
                cursor.moveToFirst();  
                // String imgNo = cursor.getString(0); // 圖片編號(hào)  
                String v_path = cursor.getString(1); // 圖片文件路徑  
                String v_size = cursor.getString(2); // 圖片大小  
                String v_name = cursor.getString(3); // 圖片文件名  
                LogUtil.e("v_path="+v_path);  
                LogUtil.e("v_size="+v_size);  
                LogUtil.e("v_name="+v_name);  
            }  
        }  
        super.onActivityResult(requestCode, resultCode, data);  
    }
