拍照上传图片与从相册中选择图片上传
来源：互联网 发布：安卓手机检测软件 知乎 编辑：程序博客网 时间：2024/04/30 15:05
手机拍照与上传图片是APP中很常用的功能。
我们先写个布局，然后代码实现。
MediaStore.ACTION_IMAGE_CAPTURE); //调用相机intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY,1);1布局
<RelativeLayout android:layout_width="match_parent" android:layout_height="wrap_content" > <include android:id="@+id/title" layout="@layout/title" /> </RelativeLayout> <LinearLayout style="@style/common_linearlayout" android:layout_width="match_parent" android:layout_height="0dp" android:layout_weight="1" android:orientation="vertical" > <ImageView android:id="@+id/load_ic" android:layout_marginTop="20dp" android:layout_width="match_parent" android:layout_height="280dp" android:scaleType="fitCenter" android:src="@drawable/takephoto" /> <FrameLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:background="#fff" android:paddingBottom="17dp" android:paddingTop="16dp" android:visibility="gone" > <RelativeLayout android:layout_width="match_parent" android:layout_height="wrap_content" > <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentRight="true" android:text="示意图" android:textColor="#fa5655" android:textSize="24sp" android:visibility="gone" /> </RelativeLayout> </FrameLayout> <TextView android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginBottom="25dp" android:layout_marginLeft="15dp" android:layout_marginTop="10dp" android:text="" android:textSize="13sp" /> <Button android:id="@+id/upload" style="@style/common_button_red" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginBottom="20dp" android:text="上传照片" /> </LinearLayout>2，拍照
//拍完照后，照片要保存的路径。String tempImg = Environment.getExternalStorageDirectory() + "/appName/"+ "temp.jpg"; private void findView() { context = this; mUpload = (Button) findViewById(R.id.upload); mloadiv = (ImageView) findViewById(R.id.load_ic); //picName 是个照片文件路径，判断这个 mloadiv 这个位置有没有照片，有的话，直接设置到这。 if (Util.isEmpty(picName) || picName.equals("")) { } else { Bitmap bitmap5 = BitmapUtil.getSmallBitmap(picName, true); mloadiv.setImageDrawable(new BitmapDrawable(getResources(), bitmap5)); } // 点击按钮出现dialog,选择（拍照，从相册选，取消） mUpload.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { if (uptimes >= 8) { MyToast.showToast(context, "您上传次数过多"); return; } if (dialog == null) { dialog = new AlertDialog.Builder(context).setItems( new String[]{"拍照", "从手机相册选择", "取消"}, //Dialog 中的监听器 new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { if (which == 0) { Intent intent = new Intent( MediaStore.ACTION_IMAGE_CAPTURE); intent.putExtra( MediaStore.EXTRA_VIDEO_QUALITY, 1); File out = new File(tempImg); Uri uri = Uri.fromFile(out); // 获取拍照后未压缩的原图片，并保存在uri路径中 intent.putExtra( MediaStore.EXTRA_OUTPUT, uri); // intentPhote.putExtra(MediaStore.Images.Media.ORIENTATION, // 180); startActivityForResult(intent, Config.requestCode_1); } else if (which == 1) { Intent local = new Intent(Intent.ACTION_PICK, null); local.setDataAndType(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, "image/*"); startActivityForResult(local, Config.requestCode_4); } else if (which == 2) { dialog.dismiss(); } } }).create(); } if (!dialog.isShowing()) { dialog.show(); } } }); }3，处理图片

/** * 上传图片 */ private void PicsUpload() { mDialog.show(); //开启线程上传照片 new Thread(new Runnable() { @Override public void run() { if (!isFinishing()) { try { dialog.dismiss(); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } // TODO Auto-generated method stub if (fileName1 != null) {// int imgid = DownAndUploadPic.uploadImage(flag,fileName1,// mLoginEntity.getSessionId()); int imgid = DownAndUploadPic.uploadImage(fileName1); attachmentId = imgid + ""; if (Config.isUpPicTo9999) { //上傳到9999网站 //返回图片id attachmentId9999 = DownAndUploadPicTo9999.uploadImage(fileName1); Logout.e("YCW", "attachmentId=" + attachmentId + "\nattachmentId9999=" + attachmentId9999); if (imgid != 0 && !"".equals(attachmentId9999)) { Message message = handler.obtainMessage(0); message.sendToTarget(); } else { imgid = 100; Message message = handler.obtainMessage(1); message.sendToTarget(); } } else { ////上傳到另一个网站 Logout.e("YCW", "attachmentId=" + attachmentId); if (imgid != 0) { Message message = handler.obtainMessage(0); message.sendToTarget(); } else { imgid = 100; Message message = handler.obtainMessage(1); message.sendToTarget(); } } } } } }).start(); }5 上传成功或者失败之后怎么办
private Handler handler = new Handler() { @Override public void handleMessage(Message msg) { // TODO Auto-generated method stub if(mDialog.isShowing()){ mDialog.dismiss(); } super.handleMessage(msg); switch (msg.what) { case 0: MyToast.showToast(context, "上传成功"); uptimes++; Intent intentPic = new Intent(); intentPic.putExtra("picUrl", fileName1); intentPic.putExtra("attachmentId", attachmentId); intentPic.putExtra("attachmentId9999", attachmentId9999); setResult(RESULT_OK, intentPic); finish(); break; case 1: MyToast.showToast(context, "上传失败"); break; } } };7 存储缩放的图片
