Android 2种图片(相册--拍照)的上传方式
Android 2种图片(相册–拍照)的上传方式
一 .拍照得到的图片上传
- 开始拍照的 ShootActivity
public class ShootActivity extends Activity implements View.OnClickListener {
private ImageView iv; //用于显示拍摄后的照片
private static final int PHOTO_REQUEST_TAKEPHOTO = 1;// 拍照
// 创建一个以当前时间为名称的文件
File tempFile = new File(Environment.getExternalStorageDirectory(), getPhotoFileName());
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_shoot);
btn = (Button) findViewById(R.id.btn);
iv = (ImageView) findViewById(R.id.iv);
btn.setOnClickListener(this);
}
@Override
public void onClick(View v) {
if (v.getId() == R.id.btn) {
System.out.println("点了拍照存储路径" + tempFile);
// 拍摄后的图像存储的决定位置 "/storage/emulated/0/QQ/RecentChat/dengziqi.jpg"
// 调用系统的拍照功能
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
// 指定调用相机拍照后照片的储存路径
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(tempFile));
startActivityForResult(intent, PHOTO_REQUEST_TAKEPHOTO);
}
}
//得到返回的数据
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
switch (requestCode) {
case PHOTO_REQUEST_TAKEPHOTO:
if (data != null)
setPicToView(data);
break;
}
super.onActivityResult(requestCode, resultCode, data);
}
//将图片显示到imageView中
private void setPicToView(Intent picdata) {
Bundle bundle = picdata.getExtras();
if (bundle != null) {
Bitmap photo = bundle.getParcelable("data");
Drawable drawable = new BitmapDrawable(photo);
iv.setBackgroundDrawable(drawable);
}
}
// 使用系统当前日期加以调整作为照片的名称
private String getPhotoFileName() {
Date date = new Date(System.currentTimeMillis());
SimpleDateFormat dateFromat = new SimpleDateFormat("'IMG'_yyyyMMdd_HHmmss");
return dateFromat.format(date) + ".jpg";
}
}2.为imageview设置绝对路径的图片(与上述代码无关,仅仅为了测试使用绝对路径显示图片)
iv = (ImageView) findViewById(R.id.iv);
BitmapFactory bf = new BitmapFactory();
final Bitmap bitmap = bf.decodeFile("/storage/emulated/0/QQ/RecentChat/dengziqi.jpg");
BitmapDrawable drawable = new BitmapDrawable(bitmap);
iv.setBackground(drawable);3.上传图片:
当我们拍摄完图片后,我们可以将生成的图片路径 –tempFile 存在一个集合中, 当上传是使用xutils或afinal等框架使用
RequestParams params = new RequestParams();
params.addBodyParameter("file", new File(tempFile));
HttpUtils http = new HttpUtils();
http.send(HttpRequest.HttpMethod.POST,
"uploadUrl....", //上传的地址
params,
new RequestCallBack<String>() {
@Override
public void onStart() {
}
@Override
public void onLoading(long total, long current, boolean isUploading) {
}
@Override
public void onSuccess(ResponseInfo<String> responseInfo) {
//上传成功
}
@Override
public void onFailure(HttpException error, String msg) {
//上传失败
}
});
二 .在图库中选择图片上传
1,选择图库的activity
public class PictureActivity extends Activity {
List<Drawable> ｍlist;//存储图片的集合
myAdapter myAdapter;
GridView mgridView;
private static final int PHOTO_REQUEST_GALLERY = 1;// 从相册中选择
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.photo_diaplay);
act = this;
ｍlist = new ArrayList<>();
initView();
}
// 初始化
private void initView() {
top_view = findViewById(R.id.topbar);
iv_updown = (ImageView) findViewById(R.id.iv_updown);
mgridView = (GridView) findViewById(R.id.gridView);
myAdapter = new myAdapter();
mgridView.setAdapter(myAdapter);
iv_updown = (Button) findViewById(R.id.iv_updown);
iv_updown.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//开启图库
Intent intent = new Intent(Intent.ACTION_PICK, null);
intent.setDataAndType(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, "image/*");
startActivityForResult(intent, PHOTO_REQUEST_GALLERY);
}
});
}
@Override
protected void onResume() {
super.onResume();
myAdapter.notifyDataSetChanged();
}
/** * 得到返回的数据 * @param requestCode * @param resultCode * @param data */
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
switch (requestCode) {
case PHOTO_REQUEST_GALLERY:
if (data != null) {
final Uri data1 = data.getData();
if (!TextUtils.isEmpty(data1.getAuthority())) {
//通过内容提供者 查询选择图片
Cursor cursor = getContentResolver().query(
data1,
new String[]{MediaStore.Images.Media.DATA},
null,
null,
null);
//返回 没找到选择图片
if (null == cursor) {
return;
}
//光标移动至开头 获取图片路径
cursor.moveToFirst();
String pathImage = cursor.getString(cursor
.getColumnIndex(MediaStore.Images.Media.DATA));
System.out.println("获取图片绝对路径 " + pathImage);
}
}
break;
}
//将进行剪裁后的图片显示到UI界面上
private void setPicToView(Intent picdata) {
Bundle bundle = picdata.getExtras();
if (bundle != null) {
Bitmap photo = bundle.getParcelable("data");
Drawable drawable = new BitmapDrawable(photo);
// iv.setBackgroundDrawable(drawable);
ｍlist.add(drawable);
}
}
}
//填充 GridView 的 adapter
class myAdapter extends BaseAdapter {
public myAdapter() {
}
@Override
public int getCount() {
return ｍlist.size();
}
@Override
public Object getItem(int position) {
return null;
}
@Override
public long getItemId(int position) {
return 0;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ImageView mimageView;
if (convertView == null) {
mimageView = new ImageView(act);
mimageView.setLayoutParams(new GridView.LayoutParams(150, 150));//设置ImageView对象布局
mimageView.setPadding(8, 8, 8, 8);//设置间距
} else {
mimageView = (ImageView) convertView;
}
mimageView.setBackground(ｍlist.get(position));
return mimageView;
}
}2.得到图片的路径后,上传图片:
当我们选择完图片后,我们可以将对应的图片路径 –pathImage 存在一个集合中, 当上传是使用xutils或afinal等框架使用
RequestParams params = new RequestParams();
params.addBodyParameter("file", new File(pathImage));
HttpUtils http = new HttpUtils();
http.send(HttpRequest.HttpMethod.POST,
"uploadUrl....", //上传的地址
params,
new RequestCallBack<String>() {
@Override
public void onStart() {
}
@Override
public void onLoading(long total, long current, boolean isUploading) {
}
@Override
public void onSuccess(ResponseInfo<String> responseInfo) {
//上传成功
}
@Override
public void onFailure(HttpException error, String msg) {
//上传失败
}
});
结束语:代码没有完全写出来.只是把最核心的代码码了出来.
